Wavelets are mathematical functions

AbstractionRipples are mathematical maps that cut up informations into different frequence constituents, and so analyze each constituent with a declaration matched to its graduated table. They have advantages over traditional Fourier methods in analysing physical state of affairss where the signal contains discontinuities and crisp spikes. Ripples were developed independently in the Fieldss of mathematics, quantum natural philosophies, electrical technology, and seismal geology. Interchanges between these Fieldss during the last 10 old ages have led to many new ripple applications such as image compaction, turbulency, human vision, radio detection and ranging, and temblor anticipation. This paper introduces ripples to the interested proficient individual outside of the digital signal processing field. I describe the history of ripples get downing with Fourier, compare ripple transforms with Fourier transforms, province belongingss and other particular facets of ripples, and Coating with some interesting applications such as image compaction, musical tones, and de-noising noisy informations.1. IntroductionA ripple is a wave-like oscillation with amplitude that starts out at zero, additions, and so decreases back to nothing. It can typically be visualized as a â€Å" brief oscillation † like one might see recorded Seismograph Or bosom proctor. Generally, ripples are purposefully crafted to hold specific belongingss that make them utile for signal processing. Ripples can be combined, utilizing a â€Å" displacement, multiply and amount † technique called whirl, with parts of an unknown signal to pull out information from the unknown signal. Wavelets provide an alternate attack to traditional signal processing techniques such as Fourier analysis for interrupting a signal up into its component parts. The drive drift behind ripple analysis is their belongings of being localised in clip ( infinite ) every bit good as graduated table ( frequence ) . This provides a time-scale map of a signal, enabling the extraction of characteristics that vary in clip. This makes wavelets an ideal tool for analyzing signals of a transient or non-stationary nature.2. HistoryThe development of ripples can be linked to several separate trains of idea, get downing with Haar ‘s work in the early twentieth century. Note worthy parts to wavelet theory can be attributed to Zweig ‘s find of the uninterrupted ripple transform in 1975 ( originally called the cochlear transform and discovered while analyzing the reaction of the ear to sound ) , Pierre Goupillaud, Grossmann and Morlet ‘s preparation of what is now known as the CWT ( 1982 ) , Jan-Olov Str & A ; ouml ; mberg ‘s early work on distinct ripples ( 1983 ) , Daubechies ‘ extraneous ripples with compact support ( 1988 ) , Mallat ‘s multiresolution model ( 1989 ) , Nathalie Delprat ‘s time-frequency reading of the CWT ( 1991 ) , Newland ‘s Harmonic ripple transform ( 1993 ) and many others since.First ripple ( Haar ripple ) by Alfred Haar ( 1909 )Since the 1970s: George Zweig, Jean Morlet, Alex GrossmannSince the 1980s: Yves Meyer, St & A ; eacute ; phane Mallat, Ingrid Daubechies, Ronald Coifman, Victor Wickerhauser3. WAVELET THEORYWavelet theory is applicable to several topics. All ripple transforms may b e considered signifiers of time-frequency representation for continuous-time ( parallel ) signals and so are related to harmonic analysis. Almost all practically utile distinct ripple transforms use discrete-time filter Bankss. These filter Bankss are called the ripple and scaling coefficients in ripples nomenclature. These filter Bankss may incorporate either finite impulse response ( FIR ) or infinite impulse response ( IIR ) filters. The ripples organizing a uninterrupted ripple transform ( CWT ) are capable to the uncertainness rule of Fourier analysis respective trying theory: Given a signal with some event in it, one can non delegate at the same time an exact clip and frequence response graduated table to that event. The merchandise of the uncertainnesss of clip and frequence response graduated table has a lower edge. Therefore, in the scale gm of a uninterrupted ripple transform of this signal, such an event marks an full part in the time-scale plane, alternatively of merely one point. Besides, distinct ripple bases may be considered in the context of other signifiers of the uncertainness rule. Wavelet transforms are loosely divided into three categories: uninterrupted, distinct and multiresolution-based. Above shown diagram shows all CWT ( Continuous Wavelet ) , DWT ( Discrete Wavelet ) . These all varies with the clip and degree and all graphs obtained are above shown.4. WAVELET TRANSFORMSThere are a big figure of ripple transforms each suited for different applications. For a full list see list of wavelet-related transforms but the common 1s are listed below:Continuous ripple transform ( CWT )Discrete ripple transform ( DWT )Fast ripple transform ( FWT )Raising strategyWavelet package decomposition ( WPD )Stationary ripple transform ( SWT )5. WAVELET PACKETSThe ripple transform is really a subset of a far more various transform, the ripple package transform. Wavelet packages are peculiar additive combinations of ripples. They form bases which retain many of the perpendicularity, smoothness, and localisation belongingss of their parent ripples. The coefficients in the additive combinations are computed by a recursive algorithm doing each freshly computed ripple package coefficient s equence the root of its ain analysis tree.6. WAVELETS IN MATLABWavelet Toolbox package extends the MATLAB proficient calculating environment with graphical tools and command-line maps for developing wavelet-based algorithms for the analysis, synthesis, denoising, and compaction of signals and images. Wavelet analysis provides more precise information about signal informations than other signal analysis techniques, such as Fourier. The Wavelet Toolbox supports the synergistic geographic expedition of ripple belongingss and applications. It is utile for address and sound processing, image and picture processing, biomedical imagination, and 1-D and 2-D applications in communications and geophysical sciences.7. WAVELETS VS FOURIER TRANSFORMEach and every thing in this universe comparable to it has some similarities and unsimilarities with that same is the instance with the ripples and Fourier transform. Ripples can be compared with the Fourier transform on the footing of their similarit ies and unsimilarities which are explained as follows. Assorted sorts of similarities and unsimilarities of ripples and Fourier transform are as follows.7.1 SIMILARITIES BETWEEN FOURIER AND WAVELET TRANSFORMSThe fast Fourier transform ( FFT ) and the distinct ripple transform ( DWT ) are both additive operations that generate a information construction that containssegments of assorted lengths, normally make fulling and transforming it into a different informations vector of length. The mathematical belongingss of the matrices involved in the transforms are similar as good. The reverse transform matrix for both the FFT and the DWT is the transpose of the original. As a consequence, both transforms can be viewed as a rotary motion in map infinite to a different sphere. For the FFT, this new sphere contains footing maps that are sines and cosines. For the ripple transform, this new sphere contains more complicated footing maps called ripples, female parent ripples, or analysing ripple s. Both transforms have another similarity. The basic maps are localized in frequence, doing mathematical tools such as power spectra ( how much power is contained in a frequence interval ) and scale gms ( to be defined subsequently ) utile at picking out frequences and ciphering power distributions.7.2 DISSIMILARITIES BETWEEN FOURIER AND WAVELET TRANSFORMSThe most interesting unsimilarity between these two sorts of transforms is that single ripple maps arelocalized in space.Fourier sine and cosine maps are non. This localisation characteristic, along with ripples ‘ localisation of frequence, makes many maps and operators utilizing ripples â€Å" thin † when transformed into the ripple sphere. This spareness, in bend, consequences in a figure of utile applications such as informations compaction, observing characteristics in images, and taking noise from clip series. One manner to see the time-frequency declaration differences between the Fourier transform and the rippl e transform is to look at the footing map coverage of the time-frequency plane. The square moving ridge window truncates the sine or cosine map to suit a window of a peculiar breadth. Because a individual window is used for all frequences in the WFT, the declaration of the analysis is the same at all locations in the time-frequency plane.8. WAVELET APPLICATIONSThere are assorted sorts of applications in the field of ripples which are as follows can be explained as followsComputer and Human VisionFBI Fingerprint CompressionDenoising Noisy DataMusical Tones8.1 COMPUTER AND HUMAN VISIONIn the early 1980s, David Marr began work at MIT ‘s Artificial Intelligence Laboratory on unreal vision for automatons. He is an expert on the human ocular system and his end was to larn why the first efforts to build a automaton capable of understanding its milieus were unsuccessful. Marr believed that it was of import to set up scientific foundations for vision, and that while making so ; one mus t restrict the range of probe by excepting everything that depends on preparation, civilization, and so on, and concentrate on the mechanical or nonvoluntary facets of vision. This low-level vision is the portion that enables us to animate the 3-dimensional organisation of the physical universe around us from the excitements that stimulate the retina. He so developed working algorithmic solutions to reply each of these inquiries. Marr ‘s theory was that image processing in the human ocular system has a complicated hierarchal construction that involves several beds of processing. At each treating degree, the retinal system provides a ocular representation that scales increasingly in a geometrical mode. His statements hinged on the sensing of strength alterations. He theorized that strength alterations occur at different graduated tables in an image, so that their optimum sensing requires the usage of operators of different sizes. He besides theorized that sudden strength altera tions produce a extremum or trough in the first derived function of the image. These two hypotheses require that a vision filter have two features: it should be a differential operator, and it should be capable of being tuned to move at any coveted graduated table. Marr ‘s operator was a ripple that today is referred to as a â€Å" Marr ripple. †8.2 FBI FINGERPRINT COMPRESSIONBetween 1924 and today, the US Federal Bureau of Investigation has collected about 30 million sets of fingerprints. The archive consists chiefly of inked feelings on paper cards. Facsimile scans of the feelings are distributed among jurisprudence enforcement bureaus, but the digitisation quality is frequently low. Because a figure of legal powers are experimenting with digital storage of the prints, mutual exclusivenesss between informations formats have late become a job. This job led to a demand in the condemnable justness community for a digitisation and a compaction criterion. In 1993, the FBI ‘s Criminal Justice Information Services Division developed criterions for fingerprint digitisation and compaction in cooperation with the National Institute of Standards and Technology, Los Alamos National Laboratory, commercial sellers, and condemnable justness communities. Let ‘s set the informations storage job in position. Fingerprint images are digitized at a declaration of 500 pels per inch with 256 degrees of gray-scale information per pel. A individual fingerprint is about 700,000 pels and demands about 0.6 Mbytes to hive away. A brace of custodies, so, requires about 6 Mbytes of storage. So digitising the FBI ‘s current archive would ensue in approximately 200 TBs of informations. ( Notice that at today ‘s monetary values of about $ 900 per Gbyte for hard-disk storage, the cost of hive awaying these uncompressed images would be about 200 million dollars. ) Obviously, informations compaction is of import to convey these Numberss down.8.3 DENOISING NO ISY DATAIn diverse Fieldss from planetal scientific discipline to molecular spectrometry, scientists are faced with the job of retrieving a true signal from uncomplete, indirect or noisy informations. Can wavelets assist work out this job? The reply is surely â€Å" yes, † through a technique called ripple shrinking and thresholding methods that David Donoho has worked on for several old ages. The technique works in the undermentioned manner. When you decompose a information set utilizing ripples, you use filters that act as averaging filters and others that produce inside informations. Some of the ensuing ripple coefficients correspond to inside informations in the information set. If the inside informations are little, they might be omitted without well impacting the chief characteristics of the information set. The thought of thresholding, so, is to put to zero all coefficients that are less than a peculiar threshold. These coefficients are used in an reverse ripple transm utation to retrace the information set. Figure 6 is a brace of â€Å" before † and â€Å" after † illustrations of a atomic magnetic resonance ( NMR ) signal. The signal is transformed, threshold and inverse-transformed. The technique is a important measure frontward in managing noisy informations because the denoising is carried out without smoothing out the crisp constructions. The consequence is cleaned-up signal that still shows of import inside informations. Fig.8.3.1 displays an image created by Donoho of Ingrid Daubechies ( an active research worker in ripple analysis and the discoverer of smooth orthonormal ripples of compact support ) , and so several close-up images of her oculus: an original, an image with noise added, and eventually denoised image. To denoise the image, Donoho:transformed the image to the ripple sphere utilizing Coiflets with three disappearing minutes,applied a threshold at two standard divergences, andInverse-transformed the image to the signal sphere.8.4 MUSICAL TONESVictor Wickerhauser has suggested that ripple packages could be utile in sound synthesis. His thought is that a individual ripple package generator could replace a big figure of oscillators. Through experimentation, a instrumentalist could find combinations of moving ridge packages that produce particularly interesting sounds. Wickerhauser feels that sound synthesis is a natural usage of ripples. Say one wishes to come close the sound of a musical instrument. A sample of the notes produced by the instrument could be decomposed into its ripple package coefficients. Reproducing the note would so necessitate recharging those coefficients into a ripple package generator and playing back the consequence. Transient features such as onslaught and decay- approximately, the strength fluctuations of how the sound starts and ends- could be controlled individually ( for illustration, with envelope generators ) , or by utilizing longer wave packages and encoding those belongingss every bit good into each note. Any of these procedures could be controlled in existent clip, for illustration, by a keyboard. Notice that the musical instrument could merely every bit good be a human voice, and the notes words or phonemes. A wavelet-packet-based music synthesist could hive away many complex sounds expeditiously becauseripple package coefficients, like ripple coefficients, are largely really little for digital samples of smooth signals ; andDiscarding coefficients below a predetermined cutoff introduces merely little mistakes when we are compacting the information for smooth signals.Similarly, a wave packet-based address synthesist could be used to retrace extremely tight address signals. Figure 8.4.1 illustrates a ripple musical tone or toneburst.9. ADVANTAGES OF WAVELET TRANSFORMATIONAdvantages of ripple transmutation are as follows which are discussed below.Space and Time Efficiency ( Low Complexity of DWT ) .Generality & A ; Adaptability ( Different Basis and Wavelet Functions ) .Multiresolution Properties ( Hierarchical Representation & A ; Manipulation ) .Adaptability of the Transformation ( Different Basis Functions let different Properties of the Transformation )Transformation is Hierarchical ( Multiresolution – Properties )Transformation is Loss-FreeEfficiency of the Transformation ( Linear Time and Space Complexity for Orthogonal Wavelets )Generalization of the Transformation ( Generalization of other Transformations )CONCLUSION AND FUTURE SCOPEMost of basic ripple theory has been done. The mathematics has been worked out in tormenting item and ripple theory is now in the polish phase. The refinement phase involves generalisations and extensions of ripples, such as widening ripple package techniques. The hereafter of ripples lies in the as-yet chartless district ofapplications.Wavelet techniques have non been exhaustively worked out in applications such as practical information analysis, where for illustration discretely sampled time-series informations might necessitate to be analyzed. Such applications offer exciting avenues for geographic expedition.

Review of Six Modern Plagues

Title: Six Modern Plagues and How We Are Causing Them Apollo Casco College of DuPage Abstract This paper is a review of the book â€Å"Six Modern Plagues and How We Are Causing Them†. Discussing about the causative agents of each plague and how we increased the severity of each; Mad Cow Disease (Bovine spongiform encephalopathy), Human Immunodeficiency Virus/ Acquired Immune Deficiency Syndrome (HIV/AIDS), Salmonella, Lyme Disease, Hantavirus, and West Nile Virus. Millions of people have died because of these diseases that can easily transfer from person to person or from animal to person, by eating half cooked meat, or simply a mosquito bite.Keywords: mad cow disease, hiv/aids, salmonella, Lyme disease, Hantavirus, west Nile virus Six Modern Plagues and How We Are Causing Them Bovine spongiform encephalopathy, the technical name for mad cow disease, first struck in a cattle farm in England in 1984. The infected cow started acting strangely. As the disease progresses, the cow developed head tremors and became unsteady, then became violent. The veterinarian who is trying to diagnose what is happening with the cows concluded that the disease is attacking the brain. Further study of the brain of the infected animal revealed a sponge like appearance of the brain.It took sixteen (16) years before the authorities in agriculture pointed out what is causing the disease into the cattle. â€Å"Rendering†, recycling of animal parts that usually go to waste was turned into high protein feed for herbivores like the cows, sheep, and goats. This process was stopped on year 2000. Disregarding the dietary boundaries of animals caused bad effects on the animals itself and into humans as well by consuming their meat. Centers for Disease and Prevention alarmed the public in 1981 about the emergence of an agent capable of suppressing the immune response on humans; a new virus.Because the virus attacks the immune system, they named it â€Å"acquired immunodeficiency s yndrome†. The AIDS virus, human immunodeficiency virus (HIV) was first found on the blood of a person from Congo who is a part of malaria research; the year was 1959, and this is currently the earliest documented case of HIV-1 infection. While working at Pasteur Institute in Paris, two French virologists, Francoise Barre-Sinoussi and Luc Montagnier, identified the human immunodeficiency virus (HIV) that causes AIDS in 1983 (Abbott, Allison, & Geoff Brumfiel, 2008).HIV attacks the immune system by destroying CD4 positive (CD4+) T cells, a type of white blood cell that is vital to fighting off infection. The destruction of these cells leaves people infected with HIV vulnerable to other infections, diseases, and other complications (DOH, 2008). A Pan troglodyte troglodytes is a subspecies of chimpanzee was the primary host of human immunodeficiency virus (HIV). Transfer of bodily fluids from handling of meats of infected animals gave rise to AIDS. From the persons who prepare the meats to be sold to the market got themselves infected through cuts on their skin with blood of the infected animals.The disease will further widen its network through sex from an infected person. Salmonella typhimurium DT104, is a deadly strain that haunted people and livestock agriculture for three (3) years. Salmonella typhimurium bacteria became resistant to antibiotics because of human actions. Farm owners abused the use of antibiotics. Rather than keeping their animals clean, they find it cheaper to use antibiotics to protect them from infection due to crowded and dirty living conditions in the farm. Antibiotics are added into their diet to make them grow a little faster.Newborn calves are given antibiotics to prevent infection. They are weaned immediately after birth deprived of milk from their mother that is rich and full of antibodies. Through the phenomenon known as natural selection, each generation of the bacteria grows more resistant with the continuous exposure to dru gs. Antibiotic Fluoroquinolone worked to treat the bacteria. As most of people know that a bulls-eye rash appears when somebody had a Lyme disease. From the past, the telltale story about the bulls-eye rash was used by physicians as the main diagnostic criteria rendering a negative diagnosis.The truth is, the bulls-eye rash formation only occurs in 9% of cases (Internet, story) Deforestation decreases the population of keystone species, causing the increase of population of deer that carries the tick that causes Lyme disease. Mouse and chipmunks are also carriers of the tick. Because of radical changes people have made to the landscape, the ecological balance tipped on one side. Muscle pain, stiffness of the spine, lost of appetite, agitated, fever, shivering, are the symptoms of the disease.If detected early, a three week course of antibiotic will fix the problem. To the Navajos, Hantavirus Pulmonary Syndrome (HPS) is nothing new. A disease usually fatal infection that causes victi ms to drown on their own fluids. The disease coincides with the phenomenon known as El Nino. Strong rains make the population of mouse to increase. The mouse’s urine is the source of infection. References Last, F. M. , Last, F.

Sense and Stylistic Analysis

Sense and stylistic analysis â€Å"The Escape† I would like to consider sense and stylistic peculiarities of the text that I have recently read. The title of the story is â€Å"The Escape†, it was written by Somerset Maugham. First of all, some facts from the author’s biography. William Somerset Maugham is one of the best known English writers of the 20th century. He was born in 1874 in Paris. He received a medical degree; however he never practised medicine, but all his life he had a great desire to write.The first novel â€Å"Liza of Lambeth† he wrote at the age of 23, but it had no success. For about 10 years he wrote manifold plays and novels and starved. But he did not give up. In 1907 he produced in London a comedy of manners â€Å"Lady Frederic† which finally brought him luck. Soon afterwards Maugham became internationally celebrated. So he became independent and began to travel. He came to know Europe, the United States, China, Spain, the So uth Seas. Some of his another famous works are â€Å"Cakes and Ale†, â€Å"Moon and Sixpence†, â€Å"Ashenden†, â€Å"Don Fernando† etc.He died in 1965 at the age of 91. Now let’s return to the story â€Å"The Escape†. It relates to the relationships between men and women. The main characters of the story are the narrator, his friend Roger Charing and a woman Ruth Barlow. The plot of the story is quite simple, but interesting at the same time. At the beginning of the text the narrator proposes a thesis that â€Å"if a woman once made up her mind to marry a man nothing but instant flight could save him†. But he says that not every man could manage to escape.And here the narrator tells us a short story, settled in one complex sentence, which has something in common with the following and the main story of the text. One narrator’s friend, having realized that a woman wanted to merry him, decided for a flight. He took ship. The aut hor uses here parenthesis â€Å"with a toothbrush for all his luggage, so conscious was he of his danger and the necessity for immediate action† in order to emphasize that a man was ready for everything to escape this marriage.Then he spent a year travelling around the world, but the first person he saw when he returned was that woman he tried to flee. The irony runs through the narration, supported by such words and phrases: â€Å"instant flight†, â€Å"inevitable loom†, â€Å"menacingly†, â€Å"thinking himself safe†. So, this short story serves as the introduction to the one following below. Then the narrator says that he knew only one man who managed to extricate himself in such situation. His name was Roger Charing. He was no longer a young man, but strong and hefty, and had plenty of money.He possessed a common sense and worldy wisdom, and was prudent. But when he fell in love with Ruth Barlow, â€Å"he went down like a row of ninepins†; this simile used by the author adds to the satirical tone of the narration. Mrs. Barlow was twice a widow, and now she made up her mind to marry Roger. She was very unfortunate person, sufferings followed her; this fact is underlined in the following sentence constructed in the form of parallel construction: â€Å"If she married a husband he beat her; if she employed a broker he cheated her; if she engaged a cook she drank†.Besides, Ruth Barlow had pretty, pathetic appearance and splendid dark eyes which were always ready to fill with tears. The author uses such epithets describing her as â€Å"splendid dark eyes†, â€Å"the most moving eyes†, â€Å"poor dear†, â€Å"helpless little thing†, â€Å"lovely eyes†, â€Å"pathetic†, â€Å"unfortunate†, â€Å"rotten time†. It was not surprising that she touched the strings of Roger’s heart, and he wanted to do something for her, to protect her, to save her from the ha zards of life. And when he decided to merry her and commit such a good action, he was very proud of himself.Here we must admit that everything was not so ambiguous. At first sight we should sorry for this poor woman, be in sympathy with her, and admire Roger’s kind heart. However, we feel that all the mentioned above stylistic devices make a humorous, ironical effect, and we understand that everything is not so sweet and sincere in this story as it seems at first sight. Further on the narrator characterizes Ruth already from another side; the author uses the epithets â€Å"stupid† and â€Å"scheming† and the simile â€Å"as hard as nails†, so that we see her false nature and the narrator’s negative attitude to her.Indeed, this woman was not so helpless, defenseless and poor, but rather cunning and artful; she used her pathetic appearance and various tricks in order to achieve her purposes, to arose Roger’s compassion and in the long run to m arry him. The author gives us to comprehend that Ruth just wanted to seem helpless and poor, but indeed she was not. As for Roger, he, on a sudden, fell out of love. The phrase â€Å"on a sudden† supposes that this was not a deep, sincere feeling, but just a shallow, surface passion.Now Roger realized what the sort of woman he had to deal with. Of course, he already did not want to merry her. But it was awkward for a man to jilt a woman and in order not to get a bad reputation he needed Ruth to release him by herself. That is why he thought over one scheme. He said Ruth nothing about that change in his feelings. He remained attentive to all her wishes, he took her to dine at restaurants, he sent her flowers, he was sympathetic and charming. And they arranged to marry as soon as they found a house that suited them. Then the house-hunting began.They examined a great number of houses, but Roger always found a fault that made a house unsuitable. He said he couldn’t bear to ask his dear Ruth to live in any but the perfect house. The narrator says: â€Å"Sometimes they were too large and sometimes they were too small, sometimes they were too far from the centre of things and sometimes they were too close; sometimes they were too expensive and sometimes they wanted too many repairs; sometimes they were too stuffy and sometimes they were too airy; sometimes they were too dark and sometimes they were too bleak†.The author deliberately uses parallel constructions to emphasize the duration of the similar actions. The author ironically depicts how long they were looking for a suitable house, how many houses they examined and inspected, and how tiresome and tiring was this business. It was obvious that Roget was trying Ruth’s patience and was waiting for her to be the first to break their relations. Of course, Ruth guessed his plan and finally lost her patience. Ruth’s letter to Roger is the climax of the story, because all the events pre ceding this one have been tensing the atmosphere.Her letter, where she informed Roger she was going to merry another man, was the final point in their relationships. So Roger reached his aim. As for me, I sympathize with none of them. I think they make a pair: Ruth had a scheme to marry him, Roger had a scheme to escape. They lied to each other, they tricked each other. I think the main idea the author wanted to bring to us is the importance of being honest. He reminds that one should stay honest to a person, even if one has fallen out of love with. But the relations based on trickery and scheming are doomed from the beginning.

Virtue Essay Example | Topics and Well Written Essays - 1750 words

Virtue - Essay Example However, the systems of virtue I most identify with in Iliad are the heroism that foregrounds the warriors’ courage and strong determination to fight the enemy and restore order and justice in their territories. Moreover, this system of virtue is also found in Beowulf and Jeffrey Chaucer’s Canterbury Tales. This critic elaborates on the issue of virtue: â€Å"Aristotle’s picture of a virtuous person is one who does the right action resulting from his own inclination; if one’s inclination is pushing in the direction opposite that of doing the right thing, it would be a sign of lacking moral virtue or the presence of weakness of will† (Yan). Aristotle’s focus on the willingness to do good actions demonstrates that this aspect represents an important part of virtue that is also based on moral standards. Homer’s Iliad portrays throughout the whole poem different forms of virtues that reflect the cultural realities of the Greek. However, th e virtue I most identify with in the text represents the warriors’ courage and strong determination to fight in order to defend their nation despite the difficult conditions they face. Their high understanding of their duty and the sacrifices they make while facing ferocious enemies, hostile environment and weather and even sometimes angry gods explain their virtuous nature. This critic observes: â€Å"The warriors in the Iliad display a kind of morality, despite its dissimilarities to some modern notions of morality. Their behaviour is guided by the heroic code of glory and shame. Simplistically stated, a warrior’s worth is defined by his ability to fight in battle, in which victory brings fame and glory and defeat brings dishonour and shame† (Yan). Indeed, heroism constitutes a true virtue in the Greek society which Homer successfully depicts in the poem as both Trojans and Achaeans fight for their honor. This statement exposes Achilles’ talent as a sol dier and the fate he reserves his enemies: â€Å"Sing, O goddess, the anger of Achilles son of Peleus, that brought countless ills upon the Achaeans. Many a brave soul did it send hurrying down to Hades, and many a hero did it yield a prey to dogs and vultures, for so were the counsels of Jove fulfilled from the day on which the son of Atreus, king of men, and great Achilles, first fell out with one another† (Homer 1). This recognition of his skills as a warrior reflects a deep understanding of his duty and a strong determination to win and overcome his enemies. Besides, another example of heroism depicted in Iliad constitutes Achilles’ decision to resume war after the brutal killing of his friend Patroclus. Even though Achilles has a deep understanding of his duty, the argument he had with Agamemnon led him to stop fighting in order to express his anger and disagreement. However, his warrior spirit takes over any frustration he had when he lost his friend. He, therefo re, regains immediately his fierceness and determination to exterminate the Trojan army. This new motivation led to the killing of many of his opponents including, the brave Hector. The narrator describes: â€Å"Achilles came up to him as it were Mars himself, plumed lord of battle. From his right shoulder he brandished his terrible spear of Pelian ash, and the bronze gleamed around him like flashing fire or the rays of the rising sun. Fear fell upon Hector as he beheld him, and he dared not stay longer where he

The female respondents topped the list with the highest percent (39.3%) of separated/widowed/divorced while the male respondents led in the percentage of the married/common law couples. Only 0.2% of the male respondents reported to have been divorced. At the same time, the percent of male and female single respondents was reported to be 34% and 28.5% respectively. The respondents’ income ranged from below $15,000 to over $65,000 with majority of the respondents (32.6%) being in the income bracket of $55,000-$64,999. Only 5.7% of the respondents interviewed reported to earn below $15,000. In summary, 62.8% of the respondents interviewed said to earn an annual income of $45,000 and above. The P-value for the Chi-Square test is 0.0000.05 (significance level), leading us to fail rejecting the null hypothesis. The results for this analysis therefore show that there is no association between taking Delta and the marital status of the respondent. The P-value for the Chi-Square test is 0.000
