Compression Techniques essays

Compression Techniques essays This research describes an image representation technique that entails progressive refinement of user specified regions of interest (ROI) of large images. Progressive refinement of original quality can be accomplished in theory. However, due to heavy burden on storage resources for our applications, we restrict the refinement to about 25% of the original data resolution. Wavelet decomposition with Vector Quantization (VQ) of the high frequency components and JPEG/DCT compression of low frequency component is used as representation framework. Our software will reconstruct the region selected by the user from its wavelet decomposition at desired resolution. Further refinement from the first preview can be obtained progressively by transmitting high frequency coefficients from low resolution to high resolution, which are compressed by variant of Vector Quantization called Model Based Vector Quantization. The user will have an option of progressive build up of the ROIs until full resolution stored or terminate the transmission at any time during the progressive refinement. The entire architecture of the program is based on object oriented programming using C++. A multiresolution decomposition into wavelet coefficients provides the most useful image representation or image browsing. Image decomposition is done recursively into wavelet coefficients using the technique [2] shown in Figure 1. The given image is decomposed into low and high frequency bands along the rows and columns. The high frequency subbands are first scalar quantized and the low frequency band, LL subband of the highest-level decomposition is compressed using JPEG/DCT technique. The scalar quantization is heavier for higher resolutions and reduced successively for low resolution high frequency components. The coefficients are then further compressed by a variant of Vector ...

Boston Consulting Group Bcg Matrix Marketing Essay

Boston Consulting Group Bcg Matrix Marketing Essay BCG is a four celled matrix developed by BCG, USA. It is the most renowned corporate portfolio analysis tool. It provides a graphic representation for an organization to examine different businesses in it’s portfolio on the basis of their related market share and industry growth rates. It is a two dimensional analysis on management of SBU’s (Strategic Business Units). In other words, it is a comparative analysis of business potential and the evaluation of environment. According to this matrix, business could be classified as high or low according to their industry growth rate and relative market share. Relative Market Share = SBU Sales this year leading competitors sales this year. Market Growth Rate = Industry sales this year – Industry Sales last year. The analysis requires that both measures be calculated for each SBU. The dimension of business strength, relative market share, will measure comparative advantage indicated by market dominance. The key theory un derlying this is existence of an experience curve and that market share is achieved due to overall cost leadership. BCG matrix has four cells, with the horizontal axis representing relative market share and the vertical axis denoting market growth rate. The mid-point of relative market share is set at 1.0. if all the SBU’s are in same industry, the average growth rate of the industry is used. While, if all the SBU’s are located in different industries, then the mid-point is set at the growth rate for the economy. Resources are allocated to the business units according to their situation on the grid. The four cells of this matrix have been called as stars, cash cows, question marks and dogs. Each of these cells represents a particular type of business. BCG Matrix   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   10 x  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  1 x  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  0.1 x Figure: BCG Matrix Stars- Stars represent business units having large market share in a fast growing industry. They may generate cash but because of fast growing market, stars require huge investments to maintain their lead. Net cash flow is usually modest. SBU’s located in this cell are attractive as they are located in a robust industry and these business units are highly competitive in the industry. If successful, a star will become a cash cow when the industry matures. Cash Cows- Cash Cows represents business units having a large market share in a mature, slow growing industry. Cash cows require little investment and generate cash that can be utilized for investment in other business units. These SBU’s are the corporation’s key source of cash, and are specifically the core business. They are the base of an organization. These businesses usually follow stability strategies. When cash cows loose their appeal and move towards deterioration, then a retrenchment policy may be pursued. Question Marks- Question marks represent business units having low relative market share and located in a high growth industry. They require huge amount of cash to maintain or gain market share. They require attention to determine if the venture can be viable. Question marks are generally new goods and services which have a good commercial prospective. There is no specific strategy which can be adopted. If the firm thinks it has dominant market share, then it can adopt expansion strategy, else retrenchment strategy can be adopted. Most businesses start as question marks as the company tries to enter a high growth market in which there is already a market-share. If ignored, then question marks may become dogs, while if huge investment is made, then they have potential of becoming stars.

South Africa and the end of Apartheid (CASE) Module3 Essay

South Africa and the end of Apartheid (CASE) Module3 - Essay Example In this case, the whites, who had financial influence retorted to discrimination in that, some neighborhoods were out of bound to blacks. This meant that the nation was separated into two, black and poor versus white and rich. In this case, the nation could not function as a democracy as the whites, how took all the power did not allow African leaders to claim any form of leadership position. Additionally, the country’s economic situation was deteriorating for the blacks as all important resources were acquired by the whites who had invested in manufacturing companies. With reflection to the resources that have been reviewed and taught for this module, it is seen that South Africa compares with other nations such as German and Korea. However, while there is East and West Germany as well as North and South Korea, South Africa is similar to these nations as it has suffered period of political and social divide (History of Apartheid in South Africa, 2011). On the other hand, the situation in South Africa is different from the situations portrayed in Germany and Korea. While Germany and Korea have distinct boundaries that separate different political regimes, communist and democratic, South Africa is a solid nation which suffered from racial discrimination. With reference to British influence on the country, various executions of black people were a common trend within the nation. However, while Korean Peninsula, under contest between North and South Korea remains subject to conflict, South Africa has entered a democratic system of governance that has unified the conflicting sides (Knight, 2006). The German unification applied the concept of two-nations-one people while the Korean applies the one-nation-two-regimes. In this case, Germany has been able to sideline her political and physical differences for the sake of national and regional development. On the other hand, Korea unification has separated North and South Korea

How do old design techniques differs from the new technological ones Essay

How do old design techniques differs from the new technological ones - Essay Example Are these new methods better in quality as compared to the preceding old methods? This paper will aim at trying to answer the question concerning the quality of the old methods in design as compared to the current design methods, which have a computer-precise technological aspect. Although new technology such as CAD can deliver highly precise designs and measurements, older design methods and practices which could not depend on computer technology had some meaningful value worth preserving. One of the earliest design practices in general is a period of apprenticeship. This form of on-the-job training can be referred to as a system steeped in antiquity. For instance, the practice is mentioned in Hammurabi’s code of ancient Babylon written around 4,000 years ago: ‘A craftsman often adopted a son to learn the craft. He profited by the sons labour. If he failed to teach his son the craft, that son could prosecute him and get the contract annulled. This was a form of apprenticeship, and it is not clear that the apprentice had any filial relation’ (Horne, 1915) at this time in history. The greatest asset for a designer was the technical knowledge the apprentice could learn from his master. This method can be said of great quality as compared to the new technological design methods because the knowledge obtained in such methods of design were practical and provided contextual knowledge which is hard to get in a classroom. Compared to the ancient methods of apprenticeship instruction for great works such as the pyramids or ancient temples, design instruction practices moved away from this tradition and became largely theoretical, employing the practical element very limitedly. For instance, during the medieval period of the fifth to the fifteenth centuries AD, great cathedrals were designed throughout Western Europe by inexact measurements, probably the correlation between sets of dividers, one small, the other large. At this point in

Chinese Labor and Employment Law Essay Example for Free

Chinese Labor and Employment Law Essay In November 2001, China became a fully admitted member of the World Trade Organization and in n in international trade. China has not only become a major export power, but also an attractive investment target for world trade and investment continues to increase, its labor environment will likely attract more ? 2 1980. At least 130 million of these are migrant workers who move from relatively poor rural areas to urban and industrial centers to work. Many of these migrant workers remit portions of their earnings back to family members in their hometown. Until recently, China has typically had an oversupply of unskilled labor and a shortage of skilled and professional workers. However, in the past several years, some companies in the major industrial hubs have begun to complain about labor shortages. As a result, many companies now raise wages 10 percent or more annually to retain workers, while others have closed their doors and moved to poorer inland areas or countries with cheaper labor. Interestingly, salaries for new university graduates have stagnated university system. While university graduates start their careers with wages comparable to a factory worker, their salaries typically rise much more quickly than those factory workers. How have 35 years. Prior to the early 1980s, nearly all jobs were allocated to citizens through an administrative bureau. Employees could not choose their employer or terminate their employment. Further, regulations set an expectation that the employee would work for the same employer for her or his whole working life. Companies in this era could only terminate employees for gross misconduct. This type of labor market and social safety net was called the Iron Rice Bowl because the employer guaranteed job security and benefits to employees In other words, the benefits could not be taken away 3 In 1983, the government introduced a contract system that attempted to address the low productivity of the labor market by replacing the Iron Rice Bowl with short-term labor contracts. At first, state-owned companies resisted this trend and the government succeeded only in minimal reforms. In 1992, the N required all trade unions to be affiliated with the All-China Federation of Trade Unions (ACFTU). This effectively brought labor unions under greater control of the government. The Labor Law of 1994 liberalized the labor market. The labor law, when combined with economic reforms, resulted in more than 40 million lost jobs in government and state-owned enterprises. As a result of the reforms, the government shuttered inefficient businesses and the formerly economically dominant northeast turned into a rustbelt. Meanwhile, Chinese entrepreneurs and Hong Kong investors transformed the formerly weak southeast province of Guangdong into the largest center of manufacturing in the world. In 2008, the government introduced a Labor Contract Law that rolled back some of the laissez-faire approaches to the workforce that the government introduced in the 1990s. This new law abolished the system of at-will employment for most full-time employees and required employers to provide employees with written contracts. Since 2008, the government has also revisited its policy of tight control over the All-China Federation of Trade Unions (ACFTU). While all unions must still be approved by and affiliated with ACFTU, it appears that the government is allowing the ACFTU greater authority to advocate for the rights of workers than it did just a few years ago. That said, the government continues to imprison workers who advocate for the formation of independent trade unions. W A G ES Does China have a minimum wage? 4 Yes. There are two standards of minimum wage: monthly and hourly. Minimum wages are set at the provincial and municipal level. The government prohibits employers from reaching an agreement with employees for wages that fall below the local minimum wage standard regardless of whether the employee is still in her or his probation period or internship. A probationary period occurs at the beginning of an employment relationship and allows employers to terminate employees without severance pay up to a maximum of six months, but usually just two months. The probation period allows the employer to make sure the employee is a good fit with the employer before being locked into the full term of the employment contract. Provincial and municipal governments frequently adjust statutory minimum wages. For example, many municipalities have raised their minimum wages twice in the past year alone. Ho It depends on the locality. -time employees is RMB 1,120/month, or roughly $165. However, in the poorer inland city of Chongqing, the minimum wage is RMB 870/month, or roughly $130. Of course, purchasing wages. The relative cost of living in China is lower than in many developed countries, but even when wages are adjusted for relative prices they remain much lower than in highly developed countries. How much do factory workers earn? It depends on the locality, industry, skill level, and a host of other factors. However, several sources keep broad indices of costs for general factory labor across many regions. Although the indices are only rough estimates, they are helpful in gauging wage differentials across the country. For example, a skilled manufacturing employee in Beijing can be hired for 5 RMB 3,000/month, or roughly $445. A similar worker in the poorer inland municipality of Chongqing can be hired for RMB 1,900/month, or roughly $280. To illustrate how important geographic location is in determining wage rates, the average employee salary in Beijing is nearly three times higher than in the poor inland province of Jiangxi. Do Chinese workers get overtime? T , an employer must pay overtime compensation to any employee who works more than 40 hours per week. As a general rule, an employer cannot require overtime of more than one hour per day, or three hours per day under special circumstances, and no more than 36 hours per month. As in many other countries, white collar workers like managers and sales staff are often exempt from the overtime pay rules. The following payment schedule illustrates the overtime pay requirements. E xtended Wor king Hours Typical working day Rest day (min. one per week) (i. e. , weekend) National holiday M inimum O vertime Pay (percent of regular wages) 150 percent 200 percent 300 percent Many migrant workers desperate to earn quick money agree with the employer to work beyond the maximum overtime requirements so they can send extra money home to their families. This type of overtime work is frequently found in industrial hubs and is a contributing cause of recent labor strikes because employees who agree to these arrangements place downward price pressure on wages and upward pressure on hours. Employers are also able to maneuver around overtime regulations by applying to the local labor authorities and asking for approval to use an alternative system of working hours. What are the wage levels for workers who are paid piece-rate? 6 Piece-rate is a compensation system where the employer pays the employee for each unit produced or action performed, not on the basis of time. Piece-rate wages are still a feature of to address the exploitation of employees through piece rates. For example, workers were exploited when employers paid workers at piece-rate, but then fined them for quality defects, tardiness, or no reason at all. These penalties effectively left workers with wages far below what the employer promised the workers during the hiring process. The first principle of piece-rate wages is that employers cannot set a work quota so high that it prevents an employee from completing the work within an eight-hour day or an average 40-hour week.

Immigrants and Assimilation into American Society Essay -- Immigration

Immigrants and Assimilation into American Society Several years ago, America was taught to be a 'melting pot,' a place where immigrants of different cultures or races form an integrated society, but now America is more of a 'salad bowl' where instead of forming an incorporated entity the people who make up the bowl are unwilling to unite as one. America started as an immigrant nation and has continued to be so. People all over the world come to America for several reasons. Most people come to America voluntarily, but very few come unwillingly. For whatever reasons they may have for coming they all have to face exposure to American society. When exposed to this 'new' society they choose whether to assimilate or not. Assimilation in any society is complex. Since assimilation is not simple, people will have negative experiences when assimilating into American society. In American society, learning to speak English properly is a crucial factor in assimilation. People who have decided to come to America have found it rather difficult to assimilate into American society for several reasons. One reason being that learning a new language is or can be considerably difficult depending on your age. This is so because the act of learning a new language such as English, is much more difficult for an elderly person than for one who has not reached adolescence. According to Grognet, for elderly people there are several factors that affect their willingness to learn. Among those factors are, physical health, mental health, cultural expectations, attitude, motivation and finally the ability to acquire the correct diction, and to suitable articulation (Grognet 296-297). For a person who has not reached the prepubescent age, it is... ...accomplished the assimilation into one race, it consists of people sharing a similar identity. In the words of Richard Rodriguez, ?We are gathered together-but as individuals?we stand together, alone,? thus people will assimilate but as individual ?Americans?. Bibliography: 1.
