Differences Between Linear Block And Convolutional Codes Computer Science Essay

Differences Between Linear Block And Convolutional Codes Computer Science Essay Generally the coding theory is the detailed analysis of the properties of the codes and their suitable quality for the identified application. Codes are mainly used in cryptography, error correction , data compression and now a days it is also used for the network coding.this coding generally involves with the linear block codes, convolutional codes, turbo codes respectively. LINEAR BLOCK CODES: In coding theory, the linear block code generally referred as a error correcting code for which the obtained resultant codeword is the linear combination of any two codewords. In simple words, the linear block code possesss the linearity property that is the sum of any two codewords is also a codeword. These linear block codes are divided in to the block odes and convolutional codes, eventhough turbo codes is the combination of these two types. More efficient encoding and decodig algorithms are provided by the linear codes when compared with the other codes. (http:// en.wikipedia.org/wiki/linear codes). CONVOLUTIONAL CODES The main principle involved in the convolutional code is the weighted sum of the various input message symbols is the resultant codeword symbol. This resemblance the convolution used in the LTI systems where we find the output of a syatem by knowing the impulse response and the respective input. So hence the output of a convolutional encoder can be obtained by the convolution of the input bits with the states of the convolution encoder registers.(http://en.wikipedia.org/wiki/convolutional codes). TURBO CODES In 1993, turbo codes are developed which are the class of high performance forward error correction codes and they are also the first practical codes to come nearer to the chgannel capacity for the code rate at which reliable communication is still possible while a specific identified noise level is given. Berrou glavieux and thitimajshima introduced these turbo codes in 1993 in their paper named near Shannon limit error correcting and decoding : turbo codes. Once after the introduction of these parallel turbo codes many other types are discovered which mainly includes repeat accumulate codes, serial versions. Even the conventional FEC systems are also been applied by the iterative turbo decoding methods. (http://en.wikipedia.org/wiki/turbo ) 2. CORE OF THE PAPER 1. PRINCIPLES OF THE LINEAR BLOCK CODES A block code of length n and codewors is said to be a linear(n, k) code if and only if the k dimensional subspace of the vector space is formed by all the codewords of all the n- tuples over GF(2). A linear code of length n and rank K is the linear subspace C with dimension K of the vector space where is the finite field consisting of the q elements. Such tytpe of a code with parameter q is called a q ary code. The code is said to be as binary code or ternary code if and only if q =2 or q=3 respectively. Linear block codes are briefly described by their symbol alphabets (example: binary, ternary) and with parameters (n,m, ) where n is the codeword length in symbols. m is the total number of source symbols which are used for encoding. is the codes minimum hamming distance. Linear block codes are of many types they are: Cyclic codes Repetition codes Parity codes Polynomial codes Reed Solomon codes Algebraic geometric codes Reed muller codes Perfect codes. A. GENERATOR MATRIX AND PARITY CHECK MATRIX Since the linear codes could be considered as a linear subspace C of , so any codeword C can be represented as a linear combination of a set of basis vectors such that , C= ++.= mG Where G is the generator matrix and m is the message. B. THEORITICAL CONCEPTS: As linear subspace of , the span of the minimal set of codewords can be represented by the entire code word C. These obtained codewords are collected and combined in the rows of the matrix G known as generator matrix for the code C. Theoretically, it is the standard form of is given as G=(/A), where is the kk identity matrix and A is k(n-k) matrix. A check matrix is defined as the matrix which represents the linear function H: whose kernel is C. The generating matrix G in standard form, G=(/A), with C as a code then H=(/) is a check matrix for C. C .HAMMING CODES Hamming codes are the first codes developed for the purpose of the error correction. These are widely used in digital communication systems. For any positive integer r>=2, there exists a [-r-1,3] hamming code. Example: given the following generator matrix and parity check matrix, the linear block code is [7,4,3] hamming code. G= , D. HADAMARD CODE Hadamard codes is capable of correcting many errors and is a [, r,] linear code. Hadamard code has minimum distance and therefore can correct -1 errors. Example  : The linear block code with the following generator matrix is a [8,3,4]2 Hadamard code: E..MERITS: Linear codes are the very prominent calss of the error correcting codes. It generally includes the simple description, easy procedure for encoding, nice properties, conceptually easy decoding. If C is a linear code then the minimum distance d(c) is easy to compute. Linear codes possesss simple specifications. To specify the (n,k) linear code it is sufficient to list K linearly independent codewords where as for the non linear code words generally we have to represent with all the code words. The most important linear block codes are: Hamming codes, cyclic codes, reed Solomon codes, BCH codes, LDPC codes, turbo codes respectively. F. DEMERITS: The main drawback of the hamming code is that it has the fixed hamming distance and also it is very difficult to implement coders for large block. The detection of two error bits and ability to correct the single errored bit can be obtained from the fixed hamming distance.if we choose a code which generally allows the implementor to select the desired hamming distance will be useful or beneficial. Hammer coder practical largest possible allows for codewords of nearly 31bits only. G. APPLICATIONS (1) These linear block properties are used in many applications. Trellis shaping is generated by using the syndrome coset uniqueness property of linear block codes. (2) these are also used in sensor networks for distributed sourcecoding. (3)by using these codes phase shift can be easily corrected and detected and also multiple signals can be easily sent from onechannel. (4) some other applications include mobile phone systems which are used in CDMA.

Thomas(1991) elements of information theory john wiley and sons). 2.PRINCIPLES OF CONVOLUTIONAL CODES Convolutional codes comes under a category of error correction codes in which an n bit symbol consists of each m bit information symbol to be encoded where coderate is m/n (n>=m) and the transformation acts as a function of the last K information symbols, here the constraint lenghht of the code is denoted by K. A. .Convolutional encoder To encode data convolutinoally, we begin with K memory reegisters holding one input bit each. Until other value specified , the 0 is the initial value af all memory registers. The encoder includes n-modulo 2 adders( it can be put effort with single Boolean XOR gate ) and n generator polynomials- each adder has one of them. The left most register is feded with the an input bit m. By using those existing values in the remaining registers and the respective generatot polynomials the n bits are the encoder outputs. By bit shifting all register values to their right and have to wait for its next input input bit. The encoder continues output until all registers have returned to the zero state if there are no remaining input bits. The below figure shows the rate 1/3 of the encoder with k value (constraint length) of 3. And also the generator polynomials are =(1,1,1), =(0,1,1) and =(1,0,1) The calculation of the output bits are as follows n1 = m1 + m0 + m-1 n2 = m0 + m-1 n3 = m1 + m-1. Img.1. Rate 1/3 non-recursive, non-systematic convolutional encoder with constraint length 3. B. RECURSIVE AND NON RECURSIVE CODES The above figure shows the encoder where as the below one shows the recursive one respectively, Rate 1/2 recursive, systematic convolutional encoder with constraint length 4. It can be easily observed that the input which is encoded is included in the output sequence also. These codes are generally called as systematic. The another type of codes are generally called as non systematic codes. Generally the systematic codes are always recursive codes where as the non systematic codes are always non recursive codes. The name convolutional encoder came for it because it carry out a convolution of the input stream with the encoders impulse responses. = Where x is an input sequence, is an output sequence from output j and which is the impulse response of the output j. The discrete lineaqr time invariant system is also called as a convolutional encoder. The own transfer function itself describes the output of an encoder. The transfer function is connected by the impulse response through z transform. + (Z)= +, (Z)=1+. The second order transfer functions are: (z)= We Define m by Where for any rational functional, we define it as Where m is the maximum polynomial degrees of the . And the constraint length is defined as . C.TRELLIS DIAGRAM A convolutional encoder is also referred as finite state machine. An encoder with n binary cells produce states. Just imagine the encoder which is shown in figure 1 has 1 in left memory cell(m0) in right one. We will refer such a stete as 10. By considering input bit the encoder at the next turn can convert either to 11 state or 01 state or 01 state. from the below figure we get rhe idea of decoding if the received sequence doesnot suit this graph then it errors can be obtained and we should select closest correct sequence. All transitions which are possible are shown as below: The red line is the path of the trellis. The lines their indicate transitions where the dotted lines are 1 input and the proper lines rae 0 input. The path here represents an actual encoded sequence. One of the path is shown in red colour as an example. The figure provides an idea about the decoding. D.FREE DISTANCE AND THE ERROR DISTANCE The minimum distance between the different encoded sequences is called as the free distance. The number of errors that can be corrected by code is given as correcting capability. It is given as correcting capability. It is given as, F. DECODING CONVOLUTIONAL CODES Decoding the convolutional codes can be done by several algorithms . thye vviterbi algorithm is universally used for relatively small values of K as it is highly parallelizable and it also provides maximum likelihood performance. By using SIMD instruction set the viterbi decoders are easy to implement the software on cpu and also in VLSI hardware. Fano algorithm is the best one among the several sequential decoding algorithms through which the longer constraint lenght codes re more practically decoded. Unlike viterbi decoding sequential decoding is not have maximum probability but there will be the slight incresase in the complexity with their constraint lengfht. Giving the chance to us the long , short constraint Length codes. In early 1970s these codes are used in the pionner program in Jupiter and Saturn but made it shorter, these viterbi decoded codes, often connecyed with large reed Solomon error correction codes which generally steeps the complete bit error rate curve and it also produces the very low residual undetected error rates. These both sequential and viterbi decoding algorithm gives the hard decisions..The codeword which is most likely formed by the bits.by using the soft output viterbi algorithm an appropriate confidence measure can be added to each bit in use with the BCJR algorithm the maximum a posterior(MAP ) Soft decisions can be obtained. G. POPULAR CONVOLUTIONAL CODES The viterbi decoded convolutiona;l codes is used for the voyagev program which has a constraint length of K=7, and also rate=1/2. The more powerful codes are produced by the longer constraint lengths but the viterbi algorithm complexity increases exponentially with respect to the constraint lengths , controlling these more powerful codes to deep space machines where the extra performance increases decoder complexity. Cassine probe, mars path finder, mars exploration rover to Saturn use of K=15 AND RATE OF 1/6, 2DB Bbetter than the simplex k=7, code at a rate of 256* in decoding complexity iss performed by this code. H. MERITS To correct the errors in noisy channels these convolutional codes are frequently used. These convolutional codes perform well on very bad conditions also. These convolutional codes are generally used often in satellite communications, mobile telephony and also in voice band modems. Convolutional codes generally gives good results in lower noise environments. Convolutional codes are also used in the voice band modems( v.,32, v.17, v.34) and also in the GSM mobile phones. I. DEMERITS Even though the convolutional encoder has the simplest procedure, decoding of it is very complex task. Convolutional codes cannot provide more protection against noise. J. APPLICATIONS Convolutional codes are used in the number of the applications which aims to achieve reliable data transfer, including radio, mobile communications, digital video communications, satellite communications. By using hard decision code, these codes are implemented in concatenation( example: reed Solomon). These are more efficient. (references: tutorial on convolutional coding and decoding, the online text book: IT, inference and leaving algorithms by david J.C.Mackay). 3. PRINCIPLES OF TURBO CODES By using the block code with convolutional code and also withthe longer constraint length and large block length it is theortically possible to approach the Shannon limit. But this approach became impractical due to the processing power required to decode. By using the recursive coders and iterative soft decoders the turbo codes overcome this drawback. The main aim of the recursive coder is to make the convolutional codes with shorter constraint lengths which appears as a large constraint length of a block codes and iterative soft decoder efficiently improves the estimation of the obtained message. The below shown figure generally gives the encoder for implementation which describes a clasiical encoder which provides the general design of the turbo codes. The 3 bits of the subblock can be sended by using this encoder implementation. The m-bit block of payload data is in the first subblock. The n/2 parity bits for a well known permutation includes in the 3rd subblock which is once aga in computed with the RSC code. The total number of bits in the code are . Interleaver is a device which generally carry outb the permutation of the payload data. This turbo code encoder includes two RSC codes (identical) , , as shown in the figure. By using the concatenation scheme these are connected to each othere which is reffered as parallel concatenation. Here M acts as a memory register. The input bits are forced to appear in different sequences by the dealy line and interleaver. The input sequence appears at both outputs after completion of first iteration [, , ] because of the encoders systematic nature. = = DECODER The serial connection of two elementary decoders is said to be a decoder. Generally decoder only operates on the lower speed( ) , thus it is planned for the encoder and is for encoder. The produces delays and also hold a soft decision. Where as produces delay respectively. The error bursts which are coming from the output are scattered by the interleaver whicvh is installed between between the two decoders. Here DI refers to demultiplexing and insertion module here it acts as a switch, it generally redirects input bits to once and to at another. It feeds both , inputs with padding bits( zeroes) in off state. While considering a memory less AWGN channel and assumption is made that at the iteration, the decoder receives a pair of random variables. =(-1)+, =2(-1)+ . Here is a bit from output of encoder and , are independent noise components consists of same produces a soft decision ie; ) = and pass it to the . generally referred as logarithm of likelihood ratio. The posterior probability (APP) of bit data is defined as which shows the probability of explaining a received bit as i. But where as produces a hard decision which is a decoded bit. Viterbi algorithm is unappropiate to calculate APP, it is not used in a BCJR algorithm is used but where as for viterbi algorithm is an appropriate one. MERITS Up to now, we know so many practical error correction methods but turbo codes and low density parity check codes come very close to approach the Shannon limit , which is the theoretical limit of maximum transfer reate of information over a noisy channel. Turbo codes increases data rate with out increasing the transmitted power, or to transmit at a certain data rate they are used to decrease the amount of the power. It generally produces the best performance results pof the throughput and latency. DEMERITS Its main disadavantage is the complexity of the relative high decoding. It also has relatively high latency, which is not suitable for some applications. It is also not verymuch useful for the satellites why because the latency is produced by the transmission distance due to the limited speed of the light. These algorithms are complex in nature. APPLICATIONS 3G and 4G mobile telephony standards uses turbo codes widely. Examples: HSPA and LTE . Used in media FLO and QUALCOMM Turbo codes are also useful in NASA missions such as mars re connaissance orbiter which is another option to RS- viterbi codes. IEEE802.16 generally uses the block turbo coding and CTC(WIMAX) a wireless metropolitan standard. Turbo codes are used in the designs of the digital communication systems and also in detection, demodulation. Turbo codes in the field of the error correcting codes represents a significant development. The cable transmission, short distance communications or data storage are the future applications of the turbo codes. (references: Berrou, claude; glavieux, alian , punva, near Shannon limit error- correcting, Berrou, claude, the ten years old turbo codes are entering in to the service, france). 4. CRITICAL COMPARISION LINEAR BLOCK CODES AND CONVOLUTIONAL CODES: Convolutional codes have a regular, natural, trellis structure which are useful in the implementation of the viterbi algorithm. Where as the linear block codes have a natural but it has minimal trellis structure. In both convolutional codes and linear block codes, the estimation of viterbi algorithm can be done by number of trellis edge symbol per encoded bit. Generally convolutional codes does not provide more protection against noise than the linear block codes. Convolutional codes offers greater simplicity of implementation over a linear block codes in many cases. Convolutional codes may not have minimal trellis representation but where as the linear block codes has the minimal trellis structure. The main differences between the linear block codes and convolutional codes is that a system which is using the block codes will transmits the k data bits and then transmits the n-k reductant bits. Where as the system which uses the convolutionla codes produces n coded bits from k data bits and the codeword need not contain unaltered k data bits. The main difference between the convolutional encoder and the block encoder is that the block code related not only to the current , but also on the previous (u) number of fixed information blocks ,, That is given as, =++.. With out the memory a linear block code is merely a convolutional code. The theory of the linear block codes seems to be degenerate of the theory of the convolutional codes, the usual approach of the convolutional codes is to note the small and fixed values of n and k and also the varying values of . TURBO CODES V/S CONVOLUTIONAL CODES: There are some differences between the behaviour of turbo codes and the convolutional codes. As we know that the performance of the convolutional codes imcreases with the increasing constraint length( code complexity). This is not for the turbo codes where the best codes of the turbo codes have the small constraint lengths . With decreasing code rate the performance of the convolutional codes doesnot improve significantly. Where as for the turbo codes even for the lower coding rates it achieves a very significant coding gain. While seeing from the implementation point of view, soft output encoders and recursive decoders are essential in turbo code schemes, where as they are not that much essential in convolutional codes excluding the concatenated configuration. Criteria Convolutional codes turbo codes Larger constraint length good bad Lower coding rate indifferent good Larger free distance good indifferent Soft output decoders indiffernt good Recursive encoders Indifferent good Both the linear block codes and convolutional codes are most frequently used type codes in the practice of enginnering for the designing of the most useful codes. TURBO VS LINEAR BLOCK CODES: The turbo codes are the hybrid model of the both the linear block codes and the convolutional codes respectively. The linear block codes used in the turbo codes instead of the convolutional codes to form a turbo product code(TPC). Two hamming codes are concatenated serially with the absence of an interleaver in between them. They can perfoem well in low SNR and can be formed by any block code. The convolutional codes used in the turbo codes usually forms a parallel concatenated convolutional code(PCCC) which have the small constraint length. They are systematic. 5. SIMULATION RESULTS The simulation results of linear block codes are as follows : The dual adaptive importance sampling (DAIS) technique evaluates the word and bit error rates of linear block codes down to extreme low values. (reference: Slin and D. Costello, error correction coding : fundamentals and applications). T,he simulation of the convolutional codes are as follows: Simulations with two recursive , equal convolutional codes with an interleaver whose length is 400 and k=50, this generally provides manufacturer interoperability, because this technique achieves the improvements which is over 3.5 dB respectively over the trellis codification modulation. (reference:Concatened trellis/reed Solomon coding in DMT systems- Kschischarg). The simulation results of the turbo codes are as follows: At a rate of R=1/2 the simulation results of the turbo codes are obtained. Here length of the data block is 400 bits( assumption) and also a MAP decoder used in the simulation. From the results it is observed that for the first few iterations yield the most significant improvements in BER for any given value of . After that the results appear to converge on to a BER for each value of . ( reference: Andersen JD and zyablov vv, interleaver design for turbo coding). 6. CONCLUSION So, hence in this research paper we have discussed the principles, applications, merits and demerits of the linear block codes, convolutional codes, turbo codes respectively. We also discussed the main differences between the block codes, convolutional codes, turbo codes and presented their respective simulation results. Personally, by doing this research i learned a lot on this coding theory and also came to know the importance of these codes in the present world. The future applications of these codes are to provide the substantial improvements in communication for the satellites. 7.

Cocaine :: essays research papers

Cocaine is a drug extracted from the leaves of the coca plant. It is a potent brain stimulant and one of the most powerfully addictive drugs. Cocaine is distributed on the street in two main forms: cocaine hydrochloride is a white crystalline powder that can be snorted or dissolved in water and injected; and "crack" is cocaine hydrochloride that has been processed with ammonia or sodium bicarbonate (baking soda) and water into a freebase cocaine. These chips, chunks, or rocks can be smoked. Cocaine may be used occasionally, daily, or in a variety of compulsive, repeated-use "binges". Regardless of how it is used, cocaine is highly addictive. Crack cocaine and injected cocaine reach the brain quickly and bring an intense and immediate high. Snorted cocaine produces a high more slowly. Cocaine can produce a surge in energy, a feeling of intense pleasure, and increased confidence. The effects of powder cocaine last about 20 minutes, while the effects of "crack" last about 12 minutes. Heavy use of cocaine may produce hallucinations, paranoia, aggression, insomnia, and depression. Cocaine's effects are short lived, and once the drug leaves the brain, the user experiences a "coke crash" that includes depression, irritability, and fatigue. Many people ask is cocaine addictive? Yes. Cocaine can take over your life and cause you to lose interest in everything else. Studies in monkeys have shown that animals will work very hard (press a bar over 10,000 times) for a single injection of cocaine, choose cocaine over food and water, and take cocaine even when this behavior is punished. Animals must have their access to cocaine limited in order not to take toxic or even lethal doses. People addicted to cocaine behave similarly. They will go to great lengths to get cocaine and continue to take it even when it hurts their school or job performance and their relationships with loved ones. Do users develop a tolerance to crack or cocaine? Yes. Users may find they need more and more of the drug to get high. What are the effects of cocaine use? Cocaine stimulates the central nervous system. It acts on the "pleasure centers" of the brain, producing heightened pleasure and increased confidence. Other immediate effects include dilated pupils and elevated blood pressure, heart rate, respiratory rate, and body temperature. The pleasurable effects of powder cocaine last about 20 minutes. Occasional use can cause a stuffy or runny nose, and chronic use can ulcerate the mucous membrane of the nose. Injecting cocaine with contaminated equipment can cause AIDS, hepatitis, and other diseases. Preparation of freebase cocaine, which involves the use of volatile solvents, can result in death or injury from fire or explosion.

A Comparison Between Adolf Hitler and Benito Mussolini Essay -- Nation

A Comparison Between Adolf Hitler and Benito Mussolini There is no doubt that Adolf Hitler and Benito Mussolini shared many similar characteristics. They shared movements that were typical of National Socialism: they adopted a radical nationalism, militaristic hierarchies, violence, the cult of charismatic leadership, contempt for individual liberties and civil rights, an anti-democratic and anti-socialist orientation, and a refusal to socialize industries. Hitler and Mussolini looked upon the new form of government, which was Totalitarianism. This form of government means there is only one leader to make decisions and thus they killed or jailed all opponents. Mussolini and Hitler used this form of government after World War One to make their countries into world powers. Perhaps the most obvious similarity would be the path they took to power. In parliament Hitler and Mussolini gathered small groups of followers they would use to bully voters, Hitler’s SS and SA and Mussolini’s Brown Shirts. The point of these behind these parties was that they both expressed what voters wanted to hear. They spoke of greater job opportunities and rejuvenation of their countries. Hitler and Mussolini used violent propaganda to increase social struggle everywhere in their countries. The polarization of the society produced by this violent behavior benefited the fascist parties. Both leaders used their political strength to impose conditions on their people. Both Hitler and Mussolini were finally given the opportunity to form a government and carried out their election promises. Their ruling of power came about to be so similar because of their similar roads to power. Here we see some differences in the way Hitler and Mussolini actually came to power. Mussolini encountered many forms of resistance and had to co-exist with other competitors for power, such as the Italian monarchy and rivals even inside his own party. Hitler proved very strong right from the beginning and he brought his plans very nearly to completion, controlling the party and the country much more thoroughly than Mussolini could. The goals of these two leaders were also very alike because of their fascist ideas. The keystone of the fascist political system was the leader: every person and every group, every lobby, lay beneath him on the same level. The Italian and German fascist movements tr... ...m agreement on religion. In Italy the Catholic Church exercised a strong influence on the people. In Italy the strong presence of Catholic religion and organizations influenced Mussolini’s policies concerning women. Although the fascist ideology intended to abolish class struggle by establishing a new corporative society, its ideas about the role of women in such a society remained very conservative. Hitler had similar beliefs about the role of women in a Nazi society but he never tried to force them to stay home, indeed, he supported their participation in industrial production. Hitler’s rule was cold and calculating, his only joys were the tramping of military boots in Nazi parades and the huge applause at Nazi rallies. On the other hand Mussolini tried to appear o his people as a â€Å"superman†. It is true that the Italian dictatorship was more conservative in its application than that of Hitler’s reign of terror. But, both the fascist ideas and rulings of these two leaders proved to have some similarities worth mentioning. Both leaders left their countries with an economic and social debt to the Allies, which is still strong in the minds of many older members of the community.

Annotated Bibliography Essay

1.) How do we choose which laws are just and which ones are not? – Unjust laws are those that intentionally prohibit the person’s civil liberties, according to the articles. 2.) What laws do you see that would fit the model for what king would call unjust? – Thanks to Dr. King and other people who have impacted the past of civil rights problems I don’t see many examples of unjust laws. The use of Marijuana is encouraged to be used in some religions, although in this country it is illegal. Think of some unjust things you have witnessed and failed to act on. 1.) Had you acted on it alone, would your involvement have changed anything? – No, I would have been out numbered and possibly put myself and my children in harms way. 2.) What if we all reacted too swiftly and jointly to matter of injustice? – If most individuals would react too swiftly in a situation they would make irrational decisions and not take the time to think the situation through. 3.) How does the act of exercising of our first amendment rights, especially when we work together, help to shape the world we live in? – The problem is too many people expect other people to fix their problems, so it may be difficult to encourage many of them to use their first amendment rights. If we could get to a point of a group of people working together then yes I do feel that we would be able to decide on a reasonable, legal conclusion. 4.) How did the Occupy Wall Street Movement (OWS) use civil disobedience to  further its cause? – They worked together and came up with their solution which wouldn’t cause any more situations or violence and hostility. 5.) Considering the outcomes associated with the OWS Movement, could we claim that the days of effective civil disobedience are over? – No, in my opinion most large events that have large outcomes tend to occur at least once again in the future with double the power. Annotated bibliography Essay The violence portrayed in the media tends to make the public more aggressive and susceptible to violence by the simple factor of imitation. Moreover, due to the amount of violence exposure, the public ends up having a falsified idea of the world in which they live. Media violence has always been an emerging topic. We live in a world in which media is present in our everyday lives; whether we are watching the news, or watching a film, listening to a song, or even playing a video game. Many studies have showed a clear correlation between the amount of violence exposure and the aggressive and violent behaviour reflected in a certain individual. Moreover, after being constantly exposed to violent contents, the public ends up believing the world is a cruel and unsecure place. This topic is therefore very interesting to pursue and study in order to have a better understanding of it. The research I will follow will help show whether the media is in fact affecting the users’ minds and behaviors. Before taking on the topic I picked, I decided to go to the library to find relevant sources discussing violence in the media. I was sure to find credible and accurate sources from the AUD database, as all the articles are peer-reviewed. Moreover, as I am a media student in the school of communications and information studies, I am currently reading a book available at the library, entitled â€Å"Media, Culture and Society† by author Paul Hodkinson. It was interesting to find a section discussing television violence. There was also an interesting experiment led by Albert Bandura in order to study the behavioral effect that media violence has on the population. These sources would be extremely beneficial and useful to my research paper. Moreover, I was impressed by the great number of journal articles discussing this specific topic, and they were easy to find on the AUD database entitled Expanded Academic ASAP. I also managed to find many online sources on search engines such as Google. However, it was hard to evaluate the reliability and credibility of the sources as some important information were missing, such as the author’s name, and the date the article was published. Therefore, I chose to include only a few specific electronic sources, the ones that seemed most accurate to me. Finally, I thought it would be interesting to do a short survey consisting of questions such as the amount of TV consumed daily, the video games played, the most violent movie ever watched, if they were ever in a fight. However, my survey cannot be part of my paper as the people I  targeted were classmates, and were in majority highly educated and media literate; therefore, the media they consumed is not believed to make them more aggressive.

Meeting Scene Romeo and Juliet VS Gnomeo and Juliet Essay

The famous play Romeo and Juliet, written by William Shakespeare, is the tale of two star-crossed lovers. Romeo, the only heir of Montague, falls in love with Juliet, the heiress of Capulet, but their love is forbidden due to a rivalry between houses resulting in a double suicide. Two adaptations of William Shakespeare’s Romeo and Juliet are Asbury’s Gnomeo and Juliet (2011), portrayed as humorous through various film techniques, and Luhrmann’s Romeo and Juliet (1996), portrayed as a tragedy through similar film techniques. This will be shown through the use of film techniques like language, camera angles and mise-en-scene. Fristly, language features are used by both Luhrmann’s version of Romeo and Juliet and Asbury’s version of Gnomeo and Juliet. In Luhrmann’s Romeo and Juliet language features such as similes are being used in the meeting scene. Romeo is comparing Juliet to a saint and himself to a pilgrim. He is saying that as it’s a long last, when he finally found the object of his reverence. Romeo takes her hands, and offered to kiss away and damage he might of has caused or may have been committed in the process. This is evident when Romeo states, â€Å"If I profane with my unworthiest hand this holy shrine, the gentle sin is this: My lips, two blushing pilgrims, ready to stand to smooth that rough touch with a tender kiss.† Luhrmann’s version of Romeo and Juliet uses language to creates the feel of Romeo and Juliet falling in love with each other before they find out who they really are. The heartbreak and knowing that both parents won’t allow them together is tragic. In Asbury’s Gnomeo and Juliet play on words are used all throughout the film. In the meeting scene Gnomeo and Juliet are mucking around with each other as they both want the flower. As Juliet gets the flower from Gnomeo she states, â€Å"Who’s your Gnomeo now?† This used for when Juliet steals the Orchid from Gnomeo as they are play around with each other. This leads to Juliet flirting with Gnomeo as she develops feelings for him this creates a feel of happiness and cheerful between the character and the audience. The different language features that have been used in both films shows that the two have both constructed two different versions of William Shakespeare Romeo and Juliet. Secondly, the use of camera angles are used in Luhrmann’s Romeo and Juliet to show the tragic and emotion effect the film has on the audience. In Asbury’s Gnomeo  and Juliet the camera angle creates a romantic and humorous. This is shown in Luhrmann’s version through the low angle when Romeo and Juliet meet and realise who they actually are. The low angle is for Romeo when he runs after Juliet to see where she is going then finds her with her mother Mrs Capulet. The camera angle captures the Romeo’s facial expression, his confusion that his one true love is his family emery and now Romeo doesn’t understand why someone so prefect in his eyes could be his family worst emery of them all. In the Asbury’s version of Gnomeo and Juliet the camera angles are used to show that the film is humorous. The camera angle that has been used in the meeting scene Gnomeo and Juliet is an eye level angle; this is shown when Gnomeo and Juliet climbing up the glasshouse and when they both reach for the Orchid. The purpose behind using eye level angle is used to create the scene romantic when they touch for the first time. The camera angle is used to make the audience think that the two are in love and they are meant to be together forever right then and here. Camera angles are used in Luhrmann’s Romeo and Juliet to show the tragedy. The camera angles are used in Asbury’s Gnomeo and Juliet to show the humorous through the camera angles as Gnomeo and Juliet. In addition, the use of mise-en-scene things such as props, costumes, lighting, facial expressions and placement are used throughout both films. Luhrmann’s version of Romeo and Juliet the costumes played a big part in the meeting scene. In the scene Romeo is dressed up as a knight and Juliet is dressed up as an angel. Romeo see’s Juliet for what she really is, an angel in his eyes.

Health Consciousness Among Urban Population - 4315 Words

Market Research Project Report On: â€Å"Health Consciousness Among Urban Population† EXECUTIVE SUMMARY Our health is one of our most important asset and without health nothing else that we do would matter. Health consciousness is not just about watching out our weight but also being healthy by way of eating healthy foods and exercising to avoid illness and lead a joyful and stressful life. This project tries to understand if people today are really health conscious, whether they realize the importance of health eating and exercising. Also the project focuses on which physical activities do people prefer the most, if people have knowledge of â€Å"a balanced diet regime†, and what is their daily routine of physical activity. The†¦show more content†¦It is therefore important that when exercising, the effort must exceed that of one’s’ normal daily activities. Why the decrease in physical activity? Many people are not getting enough exercise for a variety of reasons. Not everyone knows how much exercise is enough for a start, and so they may think that theyve done enough because they go for a long walk a couple of times a week. Other people have a better idea of what they should be doing to keep fit, but just cannot find the time. It is particularly difficult for those who work full-time and have other commitments, such as family, which demand much of their time. Then, there are those who simply cannot be bothered to exercise. They could probably find the time if they wanted, but they dont want to, and so they dont. In the past, it seems that people were more active than they are today. The types of jobs that people did were different, often being more physically demanding. Plus, fewer people owned cars and so they had to either walk or cycle everywhere. Exercise was something people did without necessarily having to think about it. They just got out on their bike or walked, whereas now exercise is viewed as somewhat of an inconvenience that you have to get dressed up for and take time out of your day to do. That is why so many people join a gym – because they think joining it will give themShow MoreRelatedRunning Head : Greening Of Cities Are Amazing And Wonderful Place For People1716 Words   |  7 PagesCity Cities are amazing and wonderful place for people.

slavery and the plantation Essay - 2087 Words

slavery and the plantation During the era of slavery in the United States, not all blacks were slaves. There were a many number of free blacks, consisting of those had been freed or those in fact that were never slave. Nor did all slave work on plantations. There were nearly five hundred thousand that worked in the cities as domestic, skilled artisans and factory hands (Green, 13). But they were exceptions to the general rule. Most blacks in America were slaves on plantation-sized units in the seven states of the South. And with the invent of the cotton gin by Eli Whitney, more slaves were needed to work the ever-growing cotton game (Frazier, 14). The size of the plantations varied with the wealth of the planters. There were†¦show more content†¦In most cases, however, slaves were expected to cook the evening meal in their cabins. The food, which was issued once a week, was generally coarse and lacking in variety. The usual allocation was a peck of corn and three o f four pounds of bacon or salt pork. They were also given milk, potatoes, peas and beans, molasses, and fish. Fractional amounts, usually one-half, were allotted to each child in the family. Most slaves supplemented this meager fare by trapping coons and opossums in the fields or by stealing corn from the masters corncribs and chickens from his chicken coops. Slaves made a distinction between taking and stealing. It was considered right to take anything that belonged to white folk but it was wrong to steal the property of other slaves (Olmsted 69-72). While the diet provided to the slave kept them alive and functioning, it lacked many important nutrients, and diet-related diseases plagued slave communities. The diseases and other inflictions that befell slave include hernia, pneumonia, and lockjaw. Because of the lack of proper sanitation, slaves also suffered from dysentery and cholera more severely than the whites (Berkin, 266-267). Twice a year the slave was issued a clothes ration.
