Ph iodintics Case EssayIntroductionThe aim of this thesis is to give a systematic description of nighwhat aspects of face morphophonemic. The thesis falls into 2 chaptersThe maiden chapter, which is an introduction, presents a short sketch of the title, the problem, the purpose of the chew over,phonological governs. The second chapter is devoted to some of the basic concepts required in the study of morphophonemic. It starts with various definitions of morpheme, allomorph.The thesis ends with some conclusions, a list of bibliography. Morphophonemic Analysis designates the analytic procedures whereby paradigms with phonological alternations argon reduced to central representations and phonological convenings. The edge morphophonemic compend has a now obscure origin. In the 1940s and 1950s, m any phonologists counterfeited with a conjecture in which (roughly) all neutralizing rules were assumed to apply sooner all allophonic rules. This in effect divided the phonology into two components a neutralizing component, whose units were called morphophonemes, and a non-neutralizing component, which dealt with phonemes and allophones. This bifurcated-phonology theory is widely considered untenable today, butmorphophonemics remains a useful term for characterizing the study of neutralizing phonological rules as they apply in paradigms.When we conduct morphophonemic analysis, we seek to ramp up a connection mingled with entropy and theory. The theory in question is that morphemes are stored in the lexicon in an invariant phonemic habitus, are strung together by morphological and syntactic rules, and are indeed converted to their surface forms by a sequence of phonological rules (often neutralizing), applied in a particular decree. The purpose of morphophonemic analysis is to let out a set of underlying forms and enjoin rules that are consistent with the selective information and the payoff is that seemingly complex patterns are often reduced to si mplicity.Morphophonemic analysis whitethorn be contrasted with phonemic analysis. Phonemic analysis is a more limited form of phonological analysis that seeks only to discover the non-neutralizing (allophonic) rules of the phonology. In phonemic analysis, only the distribution and similarity of the phones is examined. Therefore, the data need not be grouped in paradigms, but need only comprise a sufficiently large and representative set of speech. Like phonemic analysis, morphophonemic analysis can be pursued with a systematic method.The main purpose of my work consists in making exact definition of a phoneme and allophone and be able to distinguish them. To understand what is morphophonemic? Problems of my work are morphophonemic and morphophonological rules, types of morphophonological changes, relation between phonology and morphophonology, closing off forms, rule ordering, morphophonology and orthography.Morphophonology (also morphophonemics, morphonology) is a branch of lingui stics which studies the interaction between morphological and phonological or phonetic processes. Its chief focus is the start changes that larn place in morphemes (minimal meaningful units) when they combine to form words. Morphophonological analysis often involves an attempt to give a series of formal rules that successfully previse the regular sound changes occurring in the morphemes of a given phraseology. Such a series of rulesconverts a theoretical underlying representation into a surface form that is actually heard. The units of which the underlying representations of morphemes are composed are sometimes called morphophonemes. The surface form puddled by the morphophonological rules whitethorn consist of phonemes (which are then compositors case to universal phonological rules to produce speech sounds or phones), or else the morphophonological analysis may bypass the phoneme stage and produce the phones itself. Morphophonemes and morphophonological rulesWhen morphemes combine, they influence each others sound structure (whether examine at a phonetic or phonemic level), resulting in antithetical variant pronunciations for the same morpheme. Morphophonology attempts to analyze these processes. A languages morphophonological structure is slackly described with a series of rules which, ideally, can predict every morphophonological alternation that final payments place in the language. An example of a morphophonological alternation in incline is provided by the plural morpheme, written as -s or -es. Its pronunciation alternates between s, z, and z, as in cats, dogs, and horses respectively. A purely phonological analysis would most likely assign to these three endings the phonemic representations /s/, /z/, /z/.On a morphophonological level, however, they may all be considered to be forms of the underlying object //z//, which is a morphophoneme. The different forms it takes are dependent on the segment at the end of the morpheme to which it attach es these dependencies are described by morphophonological rules. (The behaviour of the slope past tense ending -ed is similar it can be pronounced t, d or d, as in hoped, bobbed and added.) Note that the plural suffix -s can also influence the form taken by the preceding morpheme, as in the case of the words leaf and knife, which end with f in the singular, but pay off v in the plural (leaves, knives).On a morphophonological level these morphemes may be canvass as ending in a morphophoneme //F//, which becomes voiced when a voiced consonant (in this case the //z// of the plural ending) is attached to it. This rule may be written imageically as /F/ - voice / __ voice. In the International Phonetic Alphabet, pipes ( ) are often used to indicate a morphophonemic quite a than phonemic representation. another(prenominal) common convention is double slashes (// //), asabove, implying that the transcription is more phonemic than simply phonemic. Other conventions sometimes seen are double pipes ( ) and curling brackets ( ). Types of morphophonological changesInflected and agglutinating languages may own extremely complicated systems of morphophonemics. Examples of complex morphophonological systems entangle 1. Sandhi, the phenomenon behind the English examples of plural and past tense above, is found in to the highest degree all languages to some degree. Even Mandarin, which is sometimes said to display no morphology, nonetheless displays tone sandhi, a morphophonemic alternation. 2. Consonant gradation, found in some Uralic languages such as Finnish, Estonian, Northern Smi, and Nganasan. 3. Vowel harmony, which occurs in varying degrees in languages all around the world, notably Turkic languages. 3. Ablaut, found in English and other Germanic languages. Ablaut is the phenomenon wherein stem vowels change form depending on context, as in English sing, sang, sung. Relation between phonology and morphophonologyUntil the 1950s, many phonologists assumed that neutralizing rules generally applied before allophonic rules. Thus phonological analysis was split into two parts a morphophonological part, where neutralizing rules were comeed to derive phonemes from morphophonemes and a purely phonological part, where phones were derived from the phonemes. Since the 1960s (in particular with the work of the generative school, such as Chomsky and Halles The Sound Pattern of English) many linguists have moved away from making such a split, instead regarding the surface phones as being derived from the underlying morphophonemes (which may be referred to apply various spoken communication) through a single system of (morpho)phonological rules.The purpose of both phonemic and morphophonemic analysis is to produce simpler underlying descriptions for what appear on the surface to be complicated patterns. In purely phonemic analysis the data is just a set of words in a language, while for the purposes of morphophonemic analysis the words must be consi dered in grammatical paradigms to take account of the underlying morphemes. It is postulated that morphemes are recorded in the speakers lexicon in an invariant (morphophonemic) form, which, in a given environment, is converted by rules into a surface form. The psychoanalyst attemptsto present as completely as possible a system of underlying units (morphophonemes) and a series of rules that act on them, so as to produce surface forms consistent with the linguistic data.Isolation formsThe isolation form of a morpheme is the form in which that morpheme appears in isolation (when not subject to the effects of any other morpheme). In the case of a bound morpheme, such as the English past tense ending -ed, it will generally not be possible to identify an isolation form, since such a morpheme does not occur in isolation. It is often reasonable to assume that the isolation form of a morpheme provides its underlying representation. For example, in some American English, plant is pronounced plnt, while planting is pln, where the morpheme plant- appears in the form pln. Here the underlying form can be assumed to be //plnt//, corresponding to the isolation form, since rules can be set up to derive the reduced form pln from this (while it would be difficult or insufferable to set up rules that would derive the isolation form plnt from an underlying //pln//).This is not always the case, however sometimes the isolation form itself is subject to neutralisation that does not apply to some other instances of the morpheme. For example, the French word petit (small) is pronounced in isolation without the final t sound, although in certain derived forms (such as the feminine petite) the t is heard. If the isolation form were adopted as the underlying form, the information that there is a final t would be lost, and it would be hard to explain the appearance of the t in the inflected forms.Rule orderingMorphophonological rules are generally considered to apply in a set order. Thi s means that the application of one rule may sometimes either prevent or enable the application of another rule provided the rules are appropriately ordered. If the ordering of two rules is such that the application of the first rule can have the effect of making it possible to apply the second, then the rules are said to be in feeding order. For example, if a language has an apocope rule (A) which deletes a final vowel, and a cluster reduction rule (CR) that reduces a final consonant cluster, then the rules are in feeding order if A precedes CR, since the application of A can enable application of CR (for example, a word ending /-rpa/ is not itself subjectto CR, since the consonant cluster is not final, but if A is applied to it first, leaving /-rp/, then CR can apply). Here rule A is said to feed rule CR. If the rules are ordered such as to avoid possible feeding (in this case, if CR applies before A) then they are said to be in counter-feeding order. On the other hand, if rules a re ordered such that the application of the first rule can have the effect of preventing application of the second, then the rules are said to be in bleed order.For example, if a language has an epenthesis rule (E) that inserts a /w/ before certain vowels, and a vowel deletion rule (D) that deletes one of two consecutive vowels, then the rules are in bleeding order if E precedes D, since the application of E can prevent application of D (for example, a word containing /-iu-/ would be subject to D, but if E is applied to it first, leaving /-iwu-/, then D can no eagle-eyeder apply). Here rule E is said to bleed rule D. If the rules are ordered such as to avoid possible bleeding (in this case, if D applies before E) then they are said to be in counter-bleeding order. The terminology of feeding and bleeding is also applied to other linguistic rules, such as those of historical sound changes.Morphophonology and orthographyThe principle behind alphabetic make-up systems is that the let ters (graphemes) represent phonemes. However in many orthographies based on such systems the correspondences between graphemes and phonemes are not exact, and it is sometimes the case that certain spellings unwrap represent a words morphophonological structure rather than the purely phonological. An example of this is that the English plural morpheme is written -s regardless of whether it is pronounced as /s/ or /z/ we write cats and dogs, not dogz. The above example involves active morphology (inflection), and morphophonemic spellings are common in this context in many languages. Another type of spelling that can be described as morphophonemic is the kind that reflects the etymology of words. Such spellings are particularly common in English examples include science /sa/ vs. unconscious //, prejudice /pr/ vs. prequel /pri/, sign /san/ signature /sn/, nation /ne/ vs. nationalism /n/, and special /sp/ vs. species /spi/.Conclusions match to this chapterMorphophonology (also morphoph onemics, morphonology) is a branch of linguistics which studies 1. The phonological structure of morphemes.2. The combinatory phonic modifications of morphemes which happen when they are combined. 3. The alternative series which serve a morphological function. Examples of a morphophonological alternatives in English include these distinctions Plurals -es and -s, as in bus, buses, vs. bun, buns. Plural of -f is -ves, as in leaf, leaves.Different pronunciations for the past tense marker -ed.English, having lost its inflection, does not have much morphophonology. Inflected and agglutinating languages may have extremely complicated systems, e.g., consonant gradation. A morphophonemic rule has the form of a phonological rule, but is curtail to a particular morphological environment. Morphophonemic rules are sensitive to their environment, unlike phonological rules. Whenever morphological information is required to specify the environment for an allophonic rule, the rule is morphophonemi c. The prefix /in-/ has the allomorphs il and ir/in-/ + responsible irresponsible/in-/ + logical illogicalTherefore, there must be a morphophonemic rule which determines the allomorphs il and ir of the prefix /in-/. The purpose of both phonemic and morphophonemic analysis is to produce simpler underlying descriptions for what appear on the surface to be complicated patterns. When morphemes are clustered or grouped in words than changes in the phonological structures of these words occur. Such changes are called morphophonemic changes. Assuming that we allow phonological rules to apply in sequence, we can cycle through them using the output of the first rule as the input to the second. For many cases in the data set, at most one phonological rule introduces a geomorphologic change. But in roll, tail, or comb we see a single derivation that involves both rules. Furthermore, such cases are not rare in English. whatever word that begins with a voiceless stop and contains a vowel that precedes a voiced consonant will require the application of both rules. We use cog as an illustrative exampleAllophoneCentral to the concept of the phoneme is the idea that it may be pronounced in many different ways. In English (BBC pronunciation) we take it for granted that the r sounds in ray and tray are the same sound (i.e. the same phoneme), but in reality the two sounds are very different the r in ray is voiced and non-fricative, while the r sound in tray is voiceless and fricative. In phonemic transcription we use the same symbol r for both, but we know that the allophones of r include the voiced nonfricative sound and the voiceless fricative one . In theory a phoneme can have an infinite number of allophones, but in practice for descriptive purposes we tend to concentrate on a small number that occur most regularly.PhonemeThis is the thoroughgoing unit of phonology, which has been defined and used in many different ways. Virtually all theories of phonology hold that spok en language can be disordered down into a string of sound units (phonemes), and that each language has a small, relatively fixed set of these phonemes. Most phonemes can be put into groups for example, in English we can identify a group of plosive phonemes p, t, k, b, d a group of voiceless fricatives f, , s, , h, and so on. An important question in phoneme theory is how the analyst can establish what the phonemes of a language are. The most widely accepted view is that phonemes are contrastive and one must find cases where the fight between two words is dependent on the difference between two phonemes for example, we can prove that the difference between pin and pan depends on the vowel and that i and are different phonemes.Pairs of words that differ in just one phoneme are known as minimal pairs. We can establish the same fact about p and b by citing pin and bin. Of course, you can only start doing commutation tests like this when you have a provisional list of possible phonemes to test, so some basic phonetic analysis must precede this stage. Other fundamental concepts used in phonemic analysis of this sort are complementary distribution, free variation, distinctive feature and allophone. Different analyses of a language are possible in the case of English some phonologists claim that there are only six vowel phonemes, others that there are twenty or more (it depends on whether you count diphthongs and long vowels as single phonemes or as combinations of two phonemes). It used to be said that learning thepronunciation of a language depended on learning the somebody phonemes of the language, but this building-block view of pronunciation is looked on nowadays as an unhelpful oversimplification.PhonemicsWhen the importance of the phoneme became widely accepted, in the 1930s and 40s, many attempts were made to develop scientific ways of establishing the phonemes of a language and listing each phonemes allophones this was known as phonemics. Nowadays little im portance is given to this type of analysis, and it is considered a minor branch of phonology, except for the practical purpose of devising writing systems for previously unwritten languages.ConclusionAn allophone is a phonetic variant of a phoneme in a particular language.A phoneme is the smallest contrastive unit in the sound system of a language.A phone is one of many possible sounds in the languages of the world.Phonemics a branch of linguistic analysis involving the study of phonemes, the structure of a language in terms of phonemes.General conclusionMorphophonemics, in linguistics, study of the relationship between morphology and phonology. Morphophonemics involves an investigation of the phonological variations within morphemes, usually marking different grammatical functions e.g., the vowel changes in sleep and slept, bind and bound, useless and vanity, and the consonant alternations in knife and knives, loaf and loaves.The ways in which the morphemes of a language are vario usly represented by phonemic shapes can be regarded as a kind of code. This code is the morphophonemic system of the language. The morphophonemics of English is never so simple. There are always many instances of two or more morphemes represented by the same phonemic shape, and there are always cases in which a single morpheme is represented now by one phonemic shape, now by another. Therefore the morphophonemics of English is never trivial.Literature1. Hayes, Bruce (2009). Morphophonemic Analysis Introductory Phonology,pp. 161185. Blackwell. 2. R. Jakobson, C. G. Fant, and M.

AP Dashanchurna EssayOperating since 1912, Ayurvedia Pharmacy is one of the oldest operating pharmacies in Bangladesh. Despite its long life, it has failed to agnise its mark as one of the prominent companies in this country. It has a range of over 100 products but only four of these are prominent. Even among these four, just about are faltering and losing ground to new entrants. AP Dashanchurna (white toothpowder) is one of these products.AP Dashanchurna has been around for a very long time, but it gained popularity after the current owners took over the partnership from the giving medication in the year 1979. It gained the epitome of popularity in the years 1990-95 when this name was a household name. Regretfully, AP Dashanchurna has non been able to hold on to its glory. AP Dashanchurna is now a losing concern. The comp both has held onto this product simply because it has been one of the flagship brands of the company for a long time.The problem with AP Dashanchurna is that it has failed to capitalize on its long life and fame. In the meantime, products like Magic Toothpowder, Colgate Toothpowder, Shakti Majan etc fork up gained significant foothold in the market. These companies take a more structured approach to identifying the target market and have significantly better marketing communication. AP Dashanshurna has failed because it has not balanced its marketing communication with the target market and hence lost customers. It also failed to make use of its chief strength, the herbal makeup of the products.AP Dashanchurna is launching a new movement in an effort to rejuvenate the product. They are bringing changes in the packaging, going for television commercials and newspaper advertisements. They do not undertake any activities to find out consumer insights, and marketing communications are based only on gut feeling of the marketers.A set of recommendations have been proposed for AP Dashanchurna. Our recommended marketing campaign is focuse d on its relevant target market and its perception in the market. The whole marketing mix has been renovated and a new marketing mix has been suggested for AP Dashanchurna.

Muscular Dystrophy Disease

Muscular Dystrophy DiseaseMuscular DystrophyMuscular muscular dystrophy is when you pee thin and weak muscles. You usually fall frequently and you manoeuvre very strange. You have difficulty getting up and you cant sit up straight. It usually propels boys (r bely girls). People with Muscular Dystrophy have incorrect or missing information in their genes.The symptoms of sizable dystrophy are when you have poor balance and you cant walk straight. Sometimes you can have a curve on your spine kind of like scoliosis. You tend to walk on your toes because you cant put your feet flat. You cant even climb stairs. If the Childs heart and breathing muscles get weak, they could die before reaching the age 20 from heart failure or pneumonia.In 1830 Sir Charles Bells discovered that Muscular Dystrophy is an x-linked genetic indisposition that causes children to have progressive muscle serviceless(prenominal)ness most boys inherit this mutation from their mothers. People are born with th is problem. Its not contagious and you cant catch it from soul else who has it. Some people develop this disease when they are adults. But usually, the signs of a child having potent dystrophy appear around the ages three to five.There are m both different type of muscular dystrophies. Such as, Duchenne muscular dystrophy, Becker dystrophy, Emery- Dreifuss Muscular dystrophy, Myotonic muscular dystrophy, Limb- Gridle dystrophy, Facioscapulohumeral muscular dystrophy, Congenital dystrophy, Oculopharyngeal muscular dystrophy and Distal muscular dystrophy. Duchenne Dystrophy occurs 2 out of every 10,000 young men. It is the most perfect(a) disease out of all of the muscular dystrophies. It occurs mostly in young boys that affects children today. The signs and symptoms of muscular dystrophy may include sudden falls, Large calf muscles, difficulty getting up when lying or sitting down, difficulty running or jumping, weak leg muscles, and Mild mental retardation, in some cases .Becke r muscular dystrophy is fruityer than Duchene. It affects older boys and young men, but it progresses slower than others. The signs and the symptoms of Becker dystrophy are sympathetic to Duchenne except that Becker usually appears between the ages 12 to 16. But the latest it can appear is around the ages 25 to 30. This disease can also cause severe heart problems.Emery-Dreifuss dystrophy can appear in your early childhood or teenage years and it can only affect males. It causes muscle weakness and wasting in the lifts, upper arms, and lower legs. There can also be life threatening heart problems to the carriers. Such as the mothers, the sisters and the daughters. Muscle cut down (contractures) occur early in this disease. It can weaken your chest and pelvic muscles that means that when you breathe, it is hard to inhale oxygen because your muscles dont let you move your chest. This progresses slowly, but it causes less muscle weakness than other muscular dystrophies.Myotonic mus cular dystrophy is the most common in adults. It affects both men and women and it can appear from any time from early childhood to adulthood. In some rare cases it can appear in newborns. This symptom can get worse in coldness temperatures. It not only affects your whole body but it affects your nervous system (the brain). Which means it is going to affect your hormones and how you do simple things. Because your brain is like the dictation center, a linguistic rule person can go through puberty and do simple things like picking up a phone. But when you have these diseases, you cant grow and you cant do certain things because your brain has a dysfunction.Limb-gridle can appear in the early teens and early adulthood and it can affect males and females. Limb-girdle causes progressive weakness that begins in the hips and moves to the shoulders, arms, and legs. In 20 years, walking can be almost impossible. Sufferers are able to live there late adulthood.Facioscapulohumeral affects t he face, shoulder blade, and the upper arm bone. This form of muscular dystrophy appears in the teens to early adulthood and affects males and females. You can have short periods and rapid deterioration. The percentage is very mild for you to be completely disabled. About 50% of the people that suffer from this disease can walk their whole lives they can usually live a normal life span.People with Congenital muscular dystrophy are born with problem and it can affect either male or female. The doctors can find out if the baby has muscular dystrophy in the first few months of the Childs life or at birth. Along with severe and early contractures. You can very much have seizures when you get older.Oculopharyngeal muscular dystrophy can appear in men and women in there 40s, 50s and 60s. It causes weakness in the eye and face muscles, which may lead to difficulty swallowing and sometimes choking. Weakness in pelvic and shoulder muscles may occur later.Distal dystrophy is one of the rare forms of muscular dystrophy that affects both men and women. It causes muscle weakness in the forearm, hands, lower legs, and feet. Generally, distal dystrophy is less severe and it progresses very slowly than others.Muscular dystrophy is dominating trait. And the expectancy of muscular dystrophy ranges from 2-40 years old. The overall frequency of all LGMD (limb-gridle) syndromes has been estimated to be 5-70 per 1 million populations in several countries. But muscular dystrophy is most common in Brazil.There is no cure for muscular dystrophy but doctors and scientists are working hard to find one. Some are even trying to fix the defective genes that lead to muscular dystrophy so they go forth make the right proteins. Others are trying to make chemicals that will act like these proteins in the body.Things that will help Muscular DystrophyCertain exercises such as physical therapy can help them with stiffening muscles adept the joints.Some times teens use special braces to ensur e flexible joints and tendons. Surgery is some times used to reduce pain.Medication can help sometimes.People with heart problems are very important that heart specialists monitor their heart.

Pentium Memory Management Unit Computer Science Essay

Pentium Memory Management Unit Computer Science EssayThe chief(prenominal) aim of the research paper is to collapse Pentium Memory Management Unit. Here, certain key features associated with a fund management building block analogous section, summon, their protection, lay aside associated with MMU in form of adaptation look diversion buffer, how to optimize small master(prenominal)frame computers transaction after implementing those features etc. have been discussed. Some problems and their respective solutions related to Pentium memory management unit argon also covered. Also, the current and afterlife research work d unitary in the field of memory management is covered too. The chief(prenominal) challenge is to get accustomed with the Pentium memory management unit and analyze the crucial factors related.IntroductionA hardware comp 1nt liable in handling divergent penetrati mavins to memory passed by mainframe is know as memory management unit (MMU), which is a lso termed as summonboyd memory management unit (PMMU). The main functions of MMU bum be categorized as follows-1 interlingual rendition of practical(prenominal) holloes to animal(prenominal) extensiones which is also kn feature as virtual memory management (VMM).Memory protection amass ControlBus Arbitration swan switchingThe memory organisation for Pentium micro helpor is 4G bytes in size just as in 80386DX and 80486 micro bringors. Pentium commits a 64-bit entropy bus to hook memory organized in eight banks that each contains 512M bytes of information.Most microprocessors including Pentium also supports virtual memory concept with the help of memory management unit. Virtual memory is utilize to manage the mental imagery of physiologic memory. It gives an practise the illusion of a very large amount of memory, typically much larger than what is effectively acquirable. It supports the execution of processes partially resident in memory. Only the most recently sub programd portions of a processs talk space actually occupy physical memory-the rest of the channelise space is stored on plough until needed. The Intel Pentium microprocessor supports both division and componentation with paging.A nonher important feature supported by Pentium processors is the memory protection. This tool helps in limiting coming to certain divides or scalawags mean(a)d on prerogative take aims and thus protect life-sustaining data if kept in a franchise level with highest priority from different attacks.Intels Pentium processor also supports cache, translation look aside buffers, (TLBs), and a store buffer for temporary on-chip (and external) storage of book of instructions and data.A nonher major issue resolved by MMU is the fragmentation of memory. Some condemnations, the size of largest contiguous dislodge memory is much smaller than the total available memory because of the fragmentation issue. With virtual memory, a contiguous crease of virtua l addresses can be mapped to several non-contiguous blocks of physical memory. 1This research paper basically revolves around different functions associated with a memory management unit of Pentium processors. This includes features like virtual memory management, memory protection, and cache control and so on. Pentiums memory management unit has some problems associated with it and some benefits as well which will be covered in detail in the later part. The above mentioned features help in solving major performance issues and has given a boom to the microprocessor world. write upIn some early microprocessor designs, memory management was performed by a separate integrated circuit such as the VLSI VI475 or the Motorola 68851 used with the Motorola 68020 mainframe computer in the Macintosh II or the Z8015 used with the Zilog Z80 family of processors. Later microprocessors such as the Motorola 68030 and the ZILOG Z280 placed the MMU together with the mainframe computer on the simil ar integrated circuit, as did the Intel 80286 and later x86 microprocessors.The origin memory management unit came into existence with the release of 80286 microprocessor chip in 1982. For the first time, 80286 offered on-chip memory management which makes it sui circuit card for multitasking operations. On many a nonher(prenominal) machines, cache access time limits the quantify cycle rate and in turn it affects more than the average memory access time. thitherfore, to achieve fast access times, fitting the cache on chip was very important and this on-chip memory management paved the way.The major functionalities associated with a memory management are divideation and paging. air division unit was found first and foremost on 8086 processor which had only one purpose of serving as a gateway for 1MB physical address space. To allow easy porting from old applications to the refreshing environment, it was decided by Intel to keep the partitioning unit alive under protect-mode. Protected mode does not have fixed sized memory blocks in memory, but instead, the size and location of each segment is set in an associated data structure called a Segment variant. All memory references are accessed relative to the base address of their corresponding segment so as to allow relocation of program modules jolly easy and also avoid direct system to perform code fix-ups when it loads applications into memory. 2 With paging enabled, the processor adds an extra level of indirection to the memory translation process. kinda of serving as a physical address, an application-generated address is used by the processor to index one of its look-up tables. The corresponding entry in the table contains the actual physical address which is sent to the processor address bus. Through the use of paging, operating systems can create distinct address spaces for each running application thus simplifying memory access and preventing potential conflicts.Virtual-memory allows applicatio ns to allocate more memory than is physically available. This is done by keeping memory varlets partially in pound up and partially on disk. When a program tries to access an on-disk page, anExceptionis generated and the operating system reloads the page to allow the disruptioning application resume its execution. 2The Pentium 4 was Intels final enterprisingness in the realm of single-core CPUs. The Pentium 4 had an on-die cache memory of 8 to 16 KB. The Pentium 4 memory cache is a memory location on the CPU used to store instructions to be processed. The Pentium 4 on-die memory cache is an extremely fast memory location which stored and decoded instructions known as microcode that were about to be executed by the CPU. 3By todays standards, the Pentium 4 cache size is very lacking in capacity. This lack of cache memory kernel the CPU mustiness make more calls to force back for operating instructions. These calls to RAM are performance reducing, as the latency involved in trans ferring data from RAM is much higher than from the on-die cache. Often overlooked, the cache size of any CPU is of vast importance to predicting the performance of acomputerprocessor. While the Pentium 4s level one cache was very limited by todays standards, it was at the time of its release more than adequate for the majority of computer applications. 4Likely Pentium Pros most noticeable appendage was its on-package L2 cache, which ranged from 256 KB at introduction to 1 MB in 1997. Intel placed the L2 die(s) separately in the package which still allowed it to run at the same measure speed as the CPU core. Additionally, unlike most m oppositeboard-based cache schemes that shared the main system bus with the CPU, the Pentium Pros cache had its own back-side bus. Because of this, the CPU could read main memory and cache concurrently, greatly reducing a traditional bottleneck. The cache was also non-blocking, meaning that the processor could issue more than one cache request at a ti me (up to 4), reducing cache-miss penalties. These properties combined to produce an L2 cache that was immensely prompt than the motherboard-based caches of older processors. This cache alone gave the CPU an advantage in input/output performance over older x86 CPUs. In multiprocessor configurations, Pentium Pros integrated cache skyrocketed performance in comparison to architectures which had each CPU sharing a central cache. 4However, this far faster L2 cache did come with some complications. The processor and the cache were on separate dies in the same package and connected almost by a full-speed bus. The two or three dies had to be bonded together early in the production process, before testing was possible. This meant that a single, tiny error in either die made it necessary to discard the entire assembly. 5Technical Aspects of Pentiums Memory Management UnitVirtual Memory Management in PentiumThe memory management unit in Pentium is upward compatible with the 80386 and 80486 microprocessors. The one-dimensional address space for Pentium microprocessor is 4G bytes that means from 0 to (232 1).MMU translates the Virtual Address to Physical address in bantam than a single clock cycle for a HIT and also it minimizes the cache fetch time for a MISS. CPU generates legitimate address which are given to segmentation unit which produces business organisationar address which are then given to paging unit and thus paging unit generates physical address in main memory. Hence, paging and segmentation units are sub forms of MMUs. regard 3.1 Logical to Physical Address Translation in PentiumPentium can run in both modes i.e. real or protected. Real mode does not allow multi-tasking as there is no protection for one process to interfere with another whereas in protected mode, each process runs in a separate code segment. Segments have different fringe benefit levels preventing the lower privilege process (such as an application) to run a higher privilege one (e. g. Operating system). Pentium running in Protected mode supports both segmentation and segmentation with paging.Segmentation PentiumThis process helps in dividing programs into logical blocks and then placing them in different memory eye sockets. This makes it possible to regulate access to critical sections of the application and help determine bugs during the development process. It includes several features like to define the exact location and size of each segment in memory and set a specific privilege level to a segment which protects its content from unauthorized access. 6Segment registers are now calledsegment selectorsbecause they do not map directly to a physical address but prime to an entry of the descriptor table.Pentium CPU has six 16 bit segment registers called SELECTORS. The logical address consists of 16 bit of segment size and 32 bit number 1 printing. The beneath figure shows a multi-segment model which uses the full capabilities of the segmentation mechanis m to provide hardware enforced protection of code, data structures, and programs and tasks. This is supported by IA-32 architecture. Here, each program is given its own table of segment descriptors and its own segments. look 3.1.1.1 Multi-Dimensional ModelWhen the processor needs to translate a memory location SEGMENT OFFSET to its corresponding physical address , it takes the following steps 7Step 1 look the start of the descriptor table (GDTR register)The below figure shows CPU selectors provide index (pointer) to Segment Descriptors stored in RAM in the form of memory structures called Descriptor Tables. Then, that address is combined with the kickoff to locate a specific linear address.Figure 3.1.1.2 Selector to Descriptor and then to finally linear address in Pentium MMUStep 2 Find the Segmententry of the table this is the segment descriptor corresponding to the segment.There are two types of Descriptor tables Global Descriptor Table and Local Descriptor table.Global Descript or Table It consists of segment definitions that apply to all programs like the code belonging to operating system segments created by OS before CPU switched to protected mode.Local Descriptor Table These tables are unique to an application.This figure visits the entry of the segment table and then a segment descriptor is elect corresponding to the segment. 7Figure 3.1.1.3 Global and Local Descriptor TablePentium has a 32 bit base address which allows segments to begin at any location in its 4G bytes of memory. The below figure shows the format of a descriptor of a Pentium processor 7Figure 3.1.1.4 Pentium Descriptor changeStep 3 Find the base physical address of the segmentStep 4 Compute = + OFFSET 7Paging UnitPaging is an address translation from linear to physical address. The linear address is divided into fixed length pages and similarly the physical address space is divided into same fixed length frames. Within their respective address spaces pages and frames are number ed sequentially. The pages that have no frames assigned to them are stored on the disk. When the CPU needs to run the code on any non-assigned page, it generates a page fault exception, upon which the operating system reassigns a currently non-used frame to that page and copies the code from that page on the disk to the newly assigned RAM frame. 9Pentium MMU uses the two-level page table to translate a virtual address to a physical address. The page directory contains 1024 32-bit page directory entries (PDEs), each of which points to one of 1024 level-2 page tables. Each page table contains 1024 32-bit page table entries (PTEs), each of which points to a page in physical memory or on disk. The page directory base register (PDBR) points to the beginning of the page directory.Figure 3.1.2.1 Pentium multi-level page table 8For 4KB pages, Pentium uses a two level paging scheme in which division of the 32 bit linear address asFigure 3.1.2.2 Division of 32 bit linear addressThe below figu re shows the complete address translation process in Pentium i.e. from CPUs virtual address to main memorys physical address.Figure 3.1.2.3 Summary of Pentium address translation 8The size of a paging table is dynamic and can become large in a system that contains large memory. In Pentium, due to the 4M byte paging feature, there is just a single page directory and no page tables. Basically, this mechanism helps operating system to create VIRTUAL (faked) address space by swapping code between disk and RAM. This procedure is known as virtual memory support. 9 The paging mechanism in Pentium functions with 4K byte memory pages or with a new extension available to the Pentium with 4M byte memory pages. The 20-bit VPN is partitioned into two 10-bit chunks. VPN1 indexes a PDE in the page directory pointed at by the PDBR. The address in the PDE points to the base of some page table that is indexed by VPN2. The PPN in the PTE indexed by VPN2 is concatenated with the VPO to form the physica l address. 8Figure 3.1.2.4 Pentium knave table Translation 8Segmentation with Paging PentiumPentium supports both pure segmentation and segmentation with paging. To select a segment, program loads a selector for that segment into one of six segment registers. For e.g. CS register is a selector for code segment and DS register is a selector for data segment. Selector can specify whether segment table is Local to the process or Global to the machine. Format of a selector used in Pentium is as followsCBb4JPGfoo4-43.jpgFigure 3.1.3.1 Selector FormatThe steps required to achieve this methodology are as follows-Step 1 Use the Selector to convert the 32 bit virtual offset address to a 32 bit linear address.Step 2 Convert the 32 bit linear address to a physical address using a two-stage page table.Figure 3.1.3.2 mapping of a linear address onto a physical address 9The below figures shows the complete process of segmentation along with paging which is one of the important functionalities of Pentiums memory management unit. 9Figure 3.1.3.3 Segmentation with pagingSome modern processors allow usage of both, segmentation and paging alone or in a combination (Motorola 8030 and later, Intel 80386, 80486, and Pentium) the OS designers have a choice which is cgiven in the below table. 9SegmentationPagingNoNoSmall (embedded) systems,low overhead, high performanceNoYesLinear address spaceBSD UNIX, Windows NTYesNoBetter controlled protection and sharing.ST can be kept on chip predictableaccess times (Intel 8086)YesYesControlled protection/sharingBetter memory management.UNIX Sys. V, OS/2.Figure 3.1.3.4 Usage of segmentation and paging in different processorsIntel 80386, 486 and Pentium support the following MM scheme which is used in IBM OS/2. The diagram is shown belowFigure 3.1.3.5 Intels Memory Management scheme implemented in IBM OS/23.1.4 Optimizing Address Translation in Pentium processorsThe main goal of memory management for address translation is to have all translat ions in less than a single clock cycle for a HIT and minimize cache fetch time for a MISS. On page fault, the page must be fetched from disk and it takes millions of clock cycles which are handled by OS code. To minimize page fault rate, two methods used are-1. Smart replacement algorithms To slim down page fault rate, the most preferred replacement algorithm is least-recently used (LRU). In this, a reference bit is set to 1 in page table entry to each page and is periodically cleared to 0 by OS. A page with reference bit equal to 0 has not been used recently. 102. Fast translation using Translation Look aside Buffer Address translation would appear to require extra memory references i.e. one to access the Page table entry and then the other for actual memory access. But access to page tables has good locality and thus use a fast cache of PTEs indoors the CPU called a Translation Look-aside Buffer (TLB) where the typical rate in Pentium is 16-512 PTEs, 0.5-1 cycle for hit, 10-100 cycles for miss, 0.01%-1% miss rate. 11Page size4KB -64 KBHit Time50-100 CPU clock cyclesMiss PenaltyAccess timeTransfer time106 107 clock cycles0.8 x 106 -0.8 x 107 clock cycles0.2 x 106 -0.2 x 107 clock cyclesMiss rate0.00001% 0.001%Virtual addressspace sizeGB -16 x 1018 byteFigure 3.1.4.1 TLB ratesUsing the below mentioned two methods, TLB misses are handled (hardware or software)The page is in memory, but its physical address is missing. A new TLB entry must be created.The page is not in memory and the control is transferred to the operating system to deal with a page fault where it is handled by causing exception ( kick downstairs) using EPC and Cause register. There are two ways of handling them-Instruction page faultStore the narrate of the processLook up the page table to find the disk address of the referenced pageChoose a physical page to replaceStart a read from disk for the referenced pageExecute another process until the read completesRestart the instruction which ca used the fault 12Data access page faultOccurs in the middle of an instruction.MIPS instructions are restartable prevent the instruction from completing and restart it from the beginning.More complex machines give waying instructions (saving the state of CPU)3. The other method used to reduce the HIT time is to avoid address translation during indexing. The CPU uses virtual addresses that must be mapped to a physical address. A cache that indexes by virtual addresses is called a virtual cache, as opposed to a physical cache. A virtual cache reduces hit time since a translation from a virtual address to a physical address is not necessary on hits. Also, address translation can be done in parallel with cache access, so penalties for misses are reduced as well.Although some difficulties are associated with Virtual cache technique i.e. process switches require cache persecute. In virtual caches, different processes share the same virtual addresses even though they map to different phys ical addresses. When a process is swapped out, the cache must be purged of all entries to make sure that the new process gets the conciliate data. 13Different solutions to overcome this problem are-PID tags Increase the width of the cache address tags to include a process ID (instead of purging the cache.) The current process PID is specified by a register. If the PID does not match, it is not a hit even if the address matches.Anti-aliasing hardware A hardware solution called anti-aliasing guarantees every cache block a unique physical address. Every virtual address maps to the same location in the cache.Page coloring This software technique forces aliases to share some address bits. Therefore, the virtual address and physical address match over these bits.Using the page offset An alternative to get the best of both virtual and physical caches. If we use the page offset to index the cache, then we can overlap the virtual address translation process with the time required to read th e tags. Note that the page offset is unaffected by address translation. However, this restriction forces the cache size to be smaller than the page size.Pipelined cache access Another method to improve cache is to divide cache access into stages. This will lead to the following final givePentium 1 clock cycle per hitPentium II and III 2 clock cycles per hitPentium 4 4 clock cycles per hitIt helps in allowing faster clock, while still producing one cache hit per clock. But the problem is that it has higher branch penalty, higher load delay. 13Trace caches A trace cache is a specialized instruction cache containing instruction traces that is, sequences of instructions that are likely to be executed. It is found on Pentium 4 (NetBurst microarchitecture). It is used instead of formal instruction cache. Cache blocks contain micro-operations, rather than raw memory and contain branches and continue at branch target, thus incorporating branch prediction. Cache hit requires correct branc h prediction. The major advantage is that it makes sure instructions are available to supply the pipeline, by avoiding cache misses that result from branches and the disadvantage is that the cache whitethorn stand up the same instruction several times and it has more complex control. 13System Memory Management ModeThe system memory management mode (SMM) is on the same level as protected mode, real mode and virtual mode, but it is provided to function as a manager. The SMM is not intended to be used as an application or a system level feature. It is intended for high-level system functions such as power management and security, which most Pentiums use during operation, but that are controlled by the operating system.Access to the SMM is accomplished via a new external hardware interrupt applied to the SMI pin on the Pentium. When the SMM interrupt is activated, the processor begins executing system-level software in an area of memory called the system management RAM, or SMMRAM, call ed the SMM state dump place down. The SMI interrupt disables all other interrupts that are normally handled by user applications and the operating system. A return from the SMM interrupt is accomplished with a new instruction called RSM. RSM returns from the memory management mode interrupt and returns to the interrupted program at the point of the interruption.SMM allows the Pentium to treat the memory system as a flat 4G byte system, instead of being able to address the first 1M of memory. SMM helps in executing the software initially stored at a memory location 38000H. SMM also stores the state of the Pentium in what is called a dump record. The dump record is stored at memory locations 3FFA8H through 3FFFFH. The dump record allows a Pentium based system to enter a sleep mode and reactivate at the point of program interruption. This requires that the SMMRAM be powered during the sleep period. The Halt auto restart and I/O trap restarts are used when the SMM mode is exited by the RSM instruction. These data allow the RSM instruction to return to the halt state or return to the interrupt I/O instruction. If neither a halt nor an I/O operation is in effect upon entering the SMM mode, the RSM instruction reloads the state of the machine from the state dump and returns to the point of interruption. 14Memory protection in PentiumIn protected mode, the Intel 64 and IA-32 architectures provide a protection mechanism that operates at both the segment level and the page level. This protection mechanism provides the ability to limit access to certain segments or pages based on privilege levels. The Pentium 4 also supports four protection levels, with level 0 being the most privileged and level 3 the least.Segment and page protection is incorporated in localizing and detecting design problems and bugs. It can also be implemented into end-products to offer added robustness to operating systems, utilities software, and applications software. This protection mechanism is used to verify certain protection checks before actual memory cycle gets started such as Limit checks, type checks, privilege level checks, restriction of addressable domains and so on.The figure shows how these levels of privilege are interpreted as rings of protection. Here, the center (reserved for the most privileged code, data, and stacks) is used for the segments containing the critical software, usually the kernel of an operating system. Outer rings are used for less critical software. At each instant, a running program is at a certain level, indicated by a 2-bit field in its PSW (Program Status Word). Each segment also belongs to a certain level.Figure 3.3.1 Protection on Pentium IIMemory protection implemented by associating protection bit with each frame valid-invalid bit attached to each entry in the page tableValid indicates that the associated page is in the process logical address space, and is thus a legal page.Invalid indicates that the page is not in the process lo gical address space.As long as a program restricts itself to using segments at its own level, everything works fine. Attempts to access data at a higher level are permitted. Attempts to access data at a lower level are illegal and cause traps.3.4 Cache in Pentium ProcessorsCache control is one of the most common techniques for improving performance in computer systems (both hardware and software) is to utilize caching for much accessed information. This lowers the average cost of accessing the information, providing greater performance for the overall system. This applies in processor design, and in the Intel Pentium 4 Processor architecture, caching is a critical component of the systems performance.The Pentium 4 Processor Architecture includes multiple types and levels of cachingLevel 3 Cache This type of caching is only available on some versions of the Pentium 4 Processor (notably the Pentium 4 Xeon processors). This provides a large on-processor tertiary memory storage area t hat the processor uses for keeping information nearby. Thus, the contents of the Level 3 cache are faster to access.Level 2 Cache this type of cache is available in all versions of the Pentium 4 Processor. It is normally smaller than the Level 3 cache and is used for caching both data and code that is being used by the processor.Level 1 Cache this type of cache is used only for caching data. It is smaller than the Level 2 Cache and generally is used for the most frequently accessed information for the processor.Trace Cache this type of cache is used only for caching decoded instructions. Specifically, the processor has already broken down the normal processor instructions into micro operations and it is these micro ops that are cached by the P4 in the Trace Cache.Translation Look aside Buffer (TLB) this type of cache is used for storing virtual-to-physical memory translation information. It is an associative cache and consists of an instruction TLB and data TLB.Store Buffer thi s type of cache is used for taking arbitrary write operations and caching them so they may be written back to memory without blocking the current processor operations. This decreases contention between the processor and other parts of the system that are accessing main memory. There are 24 entries in the Pentium 4.Write Combining Buffer this is similar to the Store Buffer, except that it is specifically optimized for burst write operations to a memory region. Thus, multiple write operations can be combined into a single write back operation. There are 6 entries in the Pentium 4.The disadvantage of caching is handling the situation when the original copy is modified, thus making the cached information incorrect (or stale). A significant amount of the work done within the processor is ensuring the consistency of the cache, both for physical memory as well as for the TLBs. In the Pentium 4, physical memory caching remains coherent because the processor uses the MESI protocol. MESI def ines the state of each unique cached piece of memory, called a cache line. In the Pentium 4, a cache line is 64 bytes. Thus, with the MESI protocol, each cache line is in one of four statesModified the cache line is have by this processor and there are modifications to that cache line stored within the processor cache. No other part of the system may access the main memory for that cache line as this will obtain stale information.Exclusive the cache line is owned by this processor. No other part of the system may access the main memory for that cache line.Shared the cache line is owned by this processor. Other parts of the system may acquire shared access to the cache line and may read that particular cache line. no(prenominal) of the shared owners may modify the cache line.Invalid the cache line is in an indeterminate state for this processor. Other parts of the system may own this cache line, or it is possible that no other part of the system owns the cache line. This proces sor may not access the memory and it is not cached. 15 occurrent Problems and Solution associated with themWhen you run multiple programs (especially MS-DOS-based programs) on a Windows-based computer that has insufficient system memory (RAM) and contains an Intel Pentium Pro or Pentium II processor, information in memory may become unavailable or damaged, leading to unpredictable results. For example, copy and compare operations may not work consistently.This behavior is an indirect result of certain performance optimizations in the Intel Pentium Pro and Pentium II processors. These optimizations affect how the Windows 95 Virtual Machine Manager (VMM) performs certain memory operations, such as find out which sections of memory are not in use and can be safely freed. As a result, the Virtual Machine Manager may free the wrong pages in memory, leading to the symptoms described earlier. This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. 16There is a little problem with sharing in

We signify to make enough profit to generate a significant return for our investors and to finance continued growth and continued development in quality products. We will also maintain a friendly, fair, and creative work environment, which respects diversity, new ideas and hard work.1.3 Keys to SuccessThe main keys to the success of the Company areSecure Supply- shove for supply of post-consumer bottles and post-industrial manufacturing waste for PET raw material feed stock.Marketing Contractual arrangements for the sale of virtually all initial takings.Management Strong higher-ranking management with extensive, broad-based, industry-specific experience.1.4 Potential RisksUnavailable or scarce raw material feed stock for issueReplay is confident that it has secured good availability of low cost post-consumer PET bottles (feed stock) derived from post-consumer beverage bottles from California based recycling collectors, and has back up sources identified.Technology plighted may be unreliable or unprovenReplay will use a proven, patented technology that was highly-developed by one of its principals for the cleaning and recycling phase. The jutting division will employ commercially proven technology the industry is employing unique recycled PET technology which is used by prominent eastern U.S. manufacturers of PET extrusions.There may non be a market for the Companys productsThe Industry-wide experience of the Management Team has allowed them to identify markets for the Companys products. Their expertise and reputations have allowed them to obtain commitments for virtually all of the planned initial production.The topical anestheticization principle may not be near enough to marketsThe markets that have been identified are earlier in the western U.S., which will provide a clear-cut advantage to the Company because of freight costs and delivery timing.The Company may not be able to attract top managementThe Company has assembled a world class management team with proven ability and direct experience in the Companys market segments.Company may not meet environmental standardsThis environmentally-favorable venture provides for the development of technically feasible and economically viable solutions to PET plastic beverage bottle recycling, as well as environmentally aware in-house re-use practices which filter and ret urn roughly all of the process water to the production lines.The Company may not be able to sell all of its production capabilityThrough the Senior Managements industry-wide contacts, the Company has identified potential customers and received commitments for all of the production potential of the initial facility.Company SummaryThe Company will capitalize on the opportunities in the recycled resin and packaging markets through two main divisions a Recycling Division and a Packaging Division.Recycling DivisionUsing a patented process, the Company will create a PET cleaning and refining plant located in the western United States we have chosen this region because all 16 major North American PET recycling plants are currently located in the eastern United States or Canada, despite western states favorable recycling attitudes among consumers. Its initial annual capacity will be 46 million pounds and it will utilize bottle feed stock from California, Oregon and Washington States, which collect over 200,000,000 pounds per year. The Company will become totally vertically integrated, and use all or almost all of its recycled material in its Packaging Division. Any surplus material produced will be sold to outside companies.Packaging DivisionWe will create a plant (actual facilities to be shared with the Recycling Division) to manufacture extruded plastic roll stock tack or high-strength strapping, employing state-of-the-art technology developed to utilize recycled PET resin.The extruded opinion poll will be primarily sold to thermoformers who will convert it into high visibility packaging, as well as laminators and fabricators. The strapping will be sold to commercial users for use as package or pallet strapping.The Company currently has commitments from customers to purchase all of the initial production capacity. Excess flake will be sold to outside customers.2.1 Company OwnershipReplay Plastics is owned by the initial founders, B. Braddock, S. McGuire and C. S mith, who are the proposed three executives of the in operation(p) entity. The plan was conceived and developed by these individuals, with the intent to apply their extensive experience and contacts in the industry to building a successful profitable corporation.2.1.1 Potential divergenceOur COO, Mr. Sam McGuire, the inventor and patent holder of the recycling process to be used by the Company, is a principal in Company A of Chicago, IL. For some years, Company has designed, manufactured and assembled plastic recycling equipment, and has given us quotes on meeting our needs in this area.After a thorough investigation, Replay has found that Company A is able to source or supply the required equipment at considerably lower cost than any other company from which a quote was available. Mr. McGuire has disclosed that Company A has included a smaller than normal margin in their quote on goods they will manufacture, to cover overhead, adventure and profit which might result in a small benefit to him. They have agreed to source all of the equipment possible with no added margin.Replay has reason that the savings available outweigh any other consideration and that we will purchase the cleaning and refining equipment from Company A.2.2 fasten on-up SummaryOur start-up expenses are budgeted at $210,000, which is for the most part for on-site geldor services during facility preparation. $50,000 has been set aside for legal and accounting, $25,000 for special consulting that may be required during start up and $50,000 each for local engineering and lab equipment and supplies. $30,000 has been set aside as a contingency for the start up period.Our largest Start-up Requirement is the building of the recycling and extrusion facility. Its final value at completion is listed below as a long-term asset of $3,620,000 (excluding expensed items like consultants and engineering listed above). Aside from the building itself, we need $25,000 in machinery and fixtures, $500,000 of inventory (plastic bottle feed stock) and cash to cover us through the initial year.Start-up FundingStart-up Expenses to Fund $210,000Start-up Assets to Fund $4,790,000Total Funding Required $5,000,000AssetsNon-cash Assets from Start-up $4,145,000 hard cash Requirements from Start-up $645,000Additional Cash Raised $0Cash Balance on Starting Date $645,000Total Assets $4,790,000Liabilities and CapitalLiabilitiesCurrent Borrowing $0Long-term Liabilities $800,000Accounts Payable (Outstanding Bills) $0Other Current Liabilities (interest-free) $0Total Liabilities $800,000CapitalPlanned InvestmentFounders $1,500,000Investor $2,700,000Additional Investment Requirement $0Total Planned Investment $4,200,000passing at Start-up (Start-up Expenses) ($210,000)Total Capital $3,990,000Total Capital and Liabilities $4,790,000Total Funding $5,000,000Start-upRequirementsStart-up ExpensesLegal Accounting $50,000Stationery etc. $5,000Consultants $25,000Lab Equipment $50,000Local Engineering $50,000M isc Start up $30,000Other $0Total Start-up Expenses $210,000Start-up AssetsCash Required $645,000Start-up Inventory $500,000Other Current Assets $25,000Long-term Assets $3,620,000Total Assets $4,790,000Total Requirements $5,000,000ProductsReplay Plastics will utilize two processes in the same facility to produceCleaned and recycled plastic PET flake (RPET), recovered from post-consumer beverage bottles and manufacturing waste produced by its sheet customersExtruded roll stock sheet PET.Extruded PET high-strength strapping for securing large packages or pallet loads each using 100% RPET produced in-house3.1 Product DescriptionRoll stock sheet will be sold to custom thermoformers primarily to be used to produce high-visibility packaging. It will also be sold to manufacturers of laminates and fabricated plastic products. gritty strength PET packaging strapping is used to secure packages or pallets in such industries as lumber milling and corrugated and other write up production.Both p roducts will be extruded from post-consumer polyethylene terephthalate (PET) bottles. The recycling programs in California, Washington and Oregon collect in excess of 200,000,000 pounds of PET bottles per annum. Replay initial capacity will be 46,000,000 pounds.Using a patented process, Replay will clean and refine the PET material from the post-consumer bottle stock and post-industrial manufacturing waste. The PET flake resin produced will be extruded into roll stock sheet or high-strength strapping.Although the Company expects to convert all of its bottle feed stock into extruded products, any surplus flake will be sold to outside manufacturers.3.2 Competitive ComparisonWhile quality and delivery are important factors to our potential clients, price is most often the determining factor in a buying decision. Good-quality packaging products manufactured from recycled (less expensive) resins, as close as practical to the end customers operations, will be most competitive and achieve a significant market share. These factors have helped to determine the business parameters of Replay Plastics.3.3 SourcingIn excess of 200,000,000 pounds of post-consumer PET beverage bottles are collected and available as feed stock for manufacturers who can re-process this material into commercial products. The Company has excellent relations with the firms and associations that collect and distribute these materials and has been assured that its requirements will be available for the foreseeable future.The Company has entered negotiations with a California based source of post-consumer bottles and is confident that sufficient volumes are available on a contract basis from this source to satisfy its requirements. In addition, the Company intends to purchase production waste from its sheet customers and blend it into its feed stock.Currently, the majority of the post-consumer PET bottles collected in California, Oregon and Washington are exported to China. The Chinese have absorbed the amounts surplus to the use in North America. Their interest has kept the industry in the attitude of being able to maintain a steady price range for this bottle stock. A significant percentage of all sales of such bottle stock are managed by Plastics Recycling Corporation of California (PRCC), an industry funded marketing agency which operates samely to a co-operative. They accept bids from potential buyers on behalf of the firms which act as consolidators, which accumulate stocks from the smaller, individual bottle-recycling depots. Some amount of the available stocks are regularly bought by recyclers in eastern North America who focus on the carpet manufacturers who use RPET resin in their process, but the high cost of transport from the western U.S. makes eastern sources more desirable.Replay has a good race with Company B, one of the larger consolidators in California. Company B has indicated a desire to contract to supply Replay with all of its raw material needs. They favour to deal with a local consumer such as Replay, rather than the uncertainty and extra preparation requirements of the export market.There are other sources of post-consumer feed stock known to Replay, and we are confident that we will have sufficient materials available for our production needs.3.4 TechnologySam McGuire, a key member of our Management team, is one of the original innovators of cleaning and refining technology for post-consumer PET, and we will be utilizing his patented process in our recycling facility. Sam has worked in the establishment and operation of facilities employing similar technologies over the last several years.On the manufacturing side, Management has been an integral part of the advancement of industry practices over the last twenty years or so, and includes in their knowledge base most, if not all, of the state-of-the-art available equipment and manufacturing techniques.Market Analysis SummaryStrong demand for recycled plastics is working in th e industrys favor. Major users of plastic packaging, simply responding to consumer desires, have begun incorporating at least some recycled plastic content in their products as part of the growing interest in recycling. Recycled resin demand is on the rise as prices for the two major recycled resins, PET and HDPE, continue to hold value or appreciate against their virgin counterparts.In volume, PET is currently the number one recycled resin. Supply of recycled PET is in excess of 800 million pounds per year. This figure is expected to grow, reaching over 1 billion pounds during the next few years. The plastics industry has developed new markets and applications for recycled resins from both post-consumer and post-industrial sources.PET leads the recycled recovered resins as the most visible and valuable, and its use is increasing. Of the total 3.7 billion pounds of PET consumed in 1997, just 16% was from recycled sources. Of the more than 90 billion pounds of plastics produced annu ally in the United States, less than 5% is from recycled sources. Plastics, after aluminium, represent the second highest value material in the waste stream and have the highest projected growth rate.Markets and uses for recycled plastics are rapidly expanding. Plastic containers are being collected at the curb for recycling in nearly 500 communities, representing more than 4 million households. U.S. demand for recycled plastic will continue to expand and new markets will develop as technologies permit the competent segregation and reprocessing of high-purity resins. Improved quality of resins, environmental issues and higher prices for virgin resin will contribute to growth.Packaging is expected to be the largest market segment for recycled plastics, with sheet and lumber following. Surveys indicate that Americans are increasingly willing to collect and separate discarded packages, foregoing a degree of convenience to make products more disposable, and veritable(a)tide paying a premium for a recycled item.Increasingly, communities are refusing to consider incineration until every effort is made first to recycle public sentiment is strongly in favor of products that can be recycled or are made of recycled materials. In recent years, the household recycling rate of PET bottles has more than doubled to 30% of all PET soft drink bottles sold. In fact, PETs recycling rate is the fastest growing among all beverage containers. The future of PET recycling is even brighter than it has been in the past. PET intrinsic scrap value is second only to aluminium among container materials. The plastics industry has launched a research and development program aimed at increasing PET recycling. According to the U.S. Environmental Protection Agency (EPA), plastic soft drink bottles account for approximately 2% of the solid waste discarded in America. The EPA has set a national goal to recycle 25% of the municipal solid waste stream and the industry is committed to achieving i ts share of that important goal.The recycling industry intends to accelerate the rate of plastic recycling as part of its commitment to develop solutions to the solid waste problem. Industry analysts have projected that 50% of all PET containers will be recycled by the year 2007. More plastics will be recycled annually than any other recyclable material. Replay believes a significant answer to Americas waste problem lies in creating high value, recycled thermoformable sheet and other extruded products for the packaging market.Although more than 200 million pounds of PET post-consumer materials are collected in the western United States each year, there is presently no local cleaning and refining facility converting the bottles into resins suitable for re-manufacturing. Originally, recycled PET (RPET) was used primarily in the carpet fiber industry, which is located along the eastern seaboard. The early development of the RPET industry was therefore focused in the eastern USA, with e astern states adopting the first bottle deposit laws that resulted in collection of post-consumer bottles that can be recycled. Recently, California, Oregon and Washington have adopted bottle deposit programs, and accumulation of recyclable materials in those states has begun. With all of the cleaning and recycling plants and the majority of consumers traditionally located in the eastern part of the country, development of consumers of recycled flake and down-line products, such as film and sheet, has been purblind to develop in the West. A strong demand for post-consumer bottles from Asia has prevented the buildup of inventories and reduced the pressure for the collection industry to find or develop western markets.There is currently no independent extrusion plant of recycled polyterephthalate (PET) sheet in the western United States or Canada that services the roll stock requirements of major custom and proprietorship formers. With the development of the recycling industry for P ET starting in the eastern part of the country, and the preponderance of consumers of sheet there as well, development of independent extrusion facilities using RPET has been slow to develop. It appears that in order to attract such companies, local sources of RPET would have to available. While there are customers in the West for the products, contracting a supply and shipping it from the East makes the venture unattractive.Our founders recognize that an opportunity exists and propose a vertically integrated conversion facility that will employ state-of-the-art technologies to produce extruded sheet and high strength strapping from 100% recycled PET post-consumer bottle stock, cleaned and refined in our own facility.4.1 Target Market Segment schemaThe Company has chosen its target markets because recycled PET (RPET) is in high demand as flake resin by converters, as roll stock sheet used to produce high visibility packaging and as high strength strapping for the lumber industry. S ales are price-sensitive, so that proximity to markets and feed stock source provide a competitive edge. Replay Plastics identified an opportunity to take advantage of both circumstances in the western United States.

Robert Frost :: essays research papers

Robert Frost, perhaps the greatest American poet of the twentieth century, has brought himself great credit entry. Many critics require tried to find a faulty office to his writing, but they have had a difficult time because his writing "romanticizes the rural simplicity that he loved while probing into the mysteries of the universe (Estep 2)." Three areas of censure covered are a speakers decision in choosing, a poetry broken down into three sections, and Frosts use of metaphors and style in his writing. Born in San Francisco, but raised in New England, many of Robert Frosts poems are representations of his experiences in the northeastern parts of America. He was ruined in college never earning his degree, and for several geezerhood he supported his family by tending to a farm his grandfather bought for him. In his spare time, Frost would read and write anything and everything. Discouraged by his unsuccessful life as a poet, he packed up his bags and moved to England . He continued writing and published his first two books of poetry, which would gain him the recognition in America he had been in search of (ExpLit 1). One of Frosts most famous poems is "The Road Not Taken." This poem is about someone who comes to a tell in a path. One path is well beaten and treaded, while the early(a) is less traveled and more difficult. Is the traveler happy with the decision he has made to take the road less traveled? Many critics think he may have had second thoughts. Magills Survey of American Literature states that on that point are many contradictions throughout the poem, "He seems to contradict his own judgment. The poet appears to imply that the decision is based on evidence that is, or comes close to being an allusion" (Magill 64).The odour of the stanza and the title of the poem suggest that the traveler may be regretting his choice because by making a choice to do one thing you have to give up the opportunity to do another (Magill 74). "I kept the first for another day I shall be telling this with a sigh." Discovering Authors Modules agrees with other critics. "Is he truly happy with his choice?" The traveler doesnt ever directly say he was happy with his choice, so is he satisfied? In the poem it states, "and that has made all the difference," but has it made all the difference in a positive way (DAM 2).

Television and Media - Relationship between Society and the Media :: Exploratory Essays Research Papers

The Relationship between Society and the Media As Americans we take pride in our liberating government. But, it is essential to ask how much we, the general public, cognise about our democracy. Because of the representative structure of our government, it is in our best interest to remain as knowledgeable as possible about political affairs so that we can play an active role in our democracy by voting for candidates and issues. The media, which includes print, telecasting, and the internet, is our primary link to political events and issues. (For the purposes of this essay only print and television will be considered.) Therefore, in order to assess the success of our democracy it is necessary to assess the soundness of our media. We are lucky enough to have a media, in theory, free from government influences because of our rights to freedom of press and freedom of speech, but we are still subject to the medias interpretation and presentation of politics, as is the insecurity when depending on any source for information. So, we must address how the media informs us how successful it is at doing so and how we should respond to it.This essay will show, unfortunately, that our democracy is not as healthy as it potentially could be because of television and prints inadequate coverage of politics and the publics resultant frustration and overleap of knowledge. The reason this occurs is not because the media is trying to restrict our role in the government, but because it has other agendas to consider, such as producing maximum profits. Also, the media can take its obligatory role, much referred to as the fourth estate, to an extreme. John McManus, a former newspaper reporter and current professor at Santa Clara University researching the social responsibility of news media, specifically uses this line in his book Market-Driven Journalism Let the Citizen Beware? to explain the medias ideal role as the fourth branch of the government. The media is meant to partic ipate in our system of rules of checks and balances and check the government to ensure that it does not withhold too much power from the people. However, this can pose a problem if the media tries too hard to occur a check on the government and ends up transcending its role as the fourth estate and becoming cynical of the government. These market-driven characteristics and overzealous tendencies are conveyed in the medias choice and presentation of language.
