Analysis Power of Computers Essay -- Computer Technology

Keywords- Family Similarity Recognition, Facial Feature Extraction, Face Detection, PCA, Image Database. I. INTRODUCTION Over the last thirty years or so, face recognition is an active research area in computer vision and one of the most successful applications of image analysis and understanding. Different algorithms have been proposed by researchers for solving this problem and many of them are considered as the state of the art. Nowadays, the face recognition problem is not only important in the research area, but it is vital in the commercial applications. A general statement of the face recognition problem can be formulated as follows: Given still or video images of a scene, identify or verify one or more persons in the scene using a stored database of faces. Due to this definition well-known algorithms such as PCA [24], ICA [1], LDA [28], EBGM [27], B... ... middle of paper ... ...e considered for it. For example, humans use terms such as "entire face of person A is similar to person B" or "eyes and eyebrows of person A are similar to person B" or "profile view of person A is similar to person B" to express the similarity criteria between people. With respect to these observations, three features are utilized in the proposed method include: "The Whole Face", "The Facial Features’ Perimeter" and "The Ratio between Facial Features". These features are selected from the frontal and side view images. The facial features’ perimeter includes forehead, eyebrows and eyes, nose, mouth, chin and cheek. The ratios between facial features’ point can be calculated from the distances that are evident in Figure 1. Utilizing ratio instead of distances between the facial features' point eliminates the dependency to the image scale. These ratios are as follow:

Assessing reliability and credibility of CAM resources Essay

Assessing reliability and credibility of CAM resources - Essay Example With this context, the paper explains the applicability of acupuncture, as a CAM therapy in medical science. The paper duly assesses the reliability and credibility of this practice thereto. Additionally, the paper analyses the credibility of the sources that provide detailed information about the disease online. Acupuncture is one of the oldest forms of treatment under the Chinese traditional medicine practices. The process of medication trails pricking of needles at specific positions of the body, which effectively alters flow of energy into healthier arrays controlling and refreshing the neuron system in a human body. Acupuncture is often argued as effective in curing approximately 40 different types of diseases. Based on these grounds, acupuncture has been recognized as one of the widely effective CAM therapies. The procedure of acupuncture includes the stimulation of therapeutic methods that helps in developing manual therapeutic systems. The process involves stimulation of the body through various processes to relieve the patients from a series of diseases (Tait et al., 2002). It is in this context that the CAM practitioners are compared with the conventional medical doctors. For practicing CAM through acupuncture, practitioner recognition depends on proper accreditation from the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM). Medical doctors who have a valid medical license can avail a certification from the American Academy of Medical Acupuncture. The person availing for a certification of acupuncture completes the necessary curriculum requirements and a tutorial requirement for the apprentice (NCCAOM, 2014). The American Academy of Medical Acupuncture (AAMA) and the NCCAOM are the regulatory bodies that have been verifying the operations of practitioners when practicing acupuncture

Principles of Macroecomomics - Essay Example 295). Figure 1. Disposable income and MPC Source: Miles and Scott (2005, p. 295) It can be found in all textbooks in macroeconomics that the MPC is related with the Keynesian income multiplier. Following Mankiw (2009, p. 373-374), the Keynesian multiplier process begins when government spends. For example, let us say that government spends ?20 billion (as mentioned earlier, Mankiw’s discussion used dollars not pounds). If the MPC is ? or 0.75 then the ?20 billion spent by government is received by society as factor payments of ?15 billion wherein, in turn, 75% of the ?15 billion are spent by those who received the payments. In turn, the factors who received the payment of 75% of the ?15 billion will spend ? of their income or 75% of 75% of ?15 billion and the chain goes on continuously. According to Mankiw (2009, p. 373), the process continually repeats and goes on indefinitely resulting into a total spending illustrated by Table 1. Table 1. MPC and multiplier resulting from i nitial government spending of ?20 billion Source: Mankiw (2009, p. 373) Based on the above, from the Keynesian perspective, government spending multiplies or increases income received by society based on the marginal propensity to consume (Mankiw 2009, p. 373-374). Based on Mankiw (2009, p. 374), the multiplier based on the MPC can be derived as: . The foregoing is equal to the following (Mankiw 2009, p. 274): . Economists are concerned with the MPC because the MPC is intimately related with the Keynesian income multiplier. It follows from the multiplier = 1/(1-MPC) that the higher MPC or the marginal propensity to consume, the higher the multiplier is. A low MPC implies a low Keynesian multiplier. As implied by our earlier discussion, Baumol and Blinder (2009, p. 160) discussion is similar but Baumol and Blinder’s take-off point for the concept of the marginal propensity to consume is disposable income rather than plain income. Disposable income refers to that part of income left after taking out taxes and the transfers payments received are added (Baumol and Blinder 2009, p. 157). Based on Baumol and Binder (2009, p. 157), at the macro level, disposable income or DI is: DI = GDP - Taxes + Transfer payments = GDP - (Taxes – Transfer payments) = Y - T. Miles and Scott (2005, p. 298) provides an interesting illustration of the Keynesian multiplier based on the modelling of the Keynesian perspective through the consumption function. In Figure 2 below, the 45 degree line is the level where spending equals income while PEo is the initial level of spending by consumers, government, and investors. A rise in government spending leads aggregate spending to PE1 such that following the Keynesian perspective, an increase in income from Yo to Y1 results. Figure 2. Marginal propensity to consume and multiplier Source: Miles and Scott (2005, p. 298) Miles and Scott (2005, p. 298) preferred, however, to say that â€Å"the multiplier shows how much demand rises once all agents have adjusted to an event that generates a change in some component of demand.† Following, this interpretation, it is important to study the MPC because initial spending by government or an increase in spending by any one or the consumer, government, or business can increase aggregate spending â€Å"once all agents have adjusted† to the initial increase in spending by any or all of the economic agents. Miles and Scott (2005, p. 299) even pointed out that â€Å"the larger is the propensity to con

Compare and contrast the immigration history of two ethnic groups Research Paper

Compare and contrast the immigration history of two ethnic groups. What factors motivated immigration and what challenges greete - Research Paper Example In this essay we are going to compare and contrast the immigration history of two Asian communities to America, which are Chinese and Japanese. These immigrations took place when America was described as ‘New World’ and ‘Land of opportunities’. However it was definitely an uphill task for these two communities to find home in America. Fighting the disparities these communities have settled themselves well in America only to be a significant section of the community and American society. Reasons for immigration Because of opium wars and end anarchical rule of Qing dynasty China lost its identity as an independent nation and was reduced to a semi-feudal colony of European powers. This drove the masses in rural and central China to look for new opportunities in order to earn money and a stable life. Chinese were not averse to hard labor but wanted good results for the hard work put in. During this time the California Gold Rush on the west coast of America had b egun. The mining of precious metal required labor which was proving to be expensive with the available white labor. Hence initially America welcomed the influx of Chinese labor on the west coast. In fact it is noted that American supervisors and companies were initially skeptical of these thin immigrants who physically did not look strong and sturdy at all. However over a period of time Chinese labor proved that they were strong and capable of handling the strenuous physical work. Companies who initially opposed the idea of recruiting Chinese immigrants later asked for more immigrants to join the work force, thus bringing in more population from China. The railroad construction which followed the mining business again proved to be a major work opportunity to Chinese people to come to America. Other businesses such as agriculture, laundry, fisheries also benefitted from the influx of Chinese people to America. Japanese economy’s transition to modern economy was not smooth. Jap anese were struggling to keep their heads above the water and float. Large scale unemployment, bankruptcies and civil disorders forced Japanese population to leave their roots behind and look for opportunities elsewhere. Hawaiian sugar industry which was booming attracted Japanese to the state. Like Chinese immigrants, Japanese were also looked upon with skepticism by Americans (Harold et al 65). Hence Chinese settled on the west coast Japanese started with the Hawaii islands. Looking at the reasons of both ethnic groups there are a lot similarities observed. Both groups left country of origin because of political and social unrest and moved for better opportunities in terms of money, societal conditions and better future. Angel Island The gateway to America for Asians was Angel Island located in San Francisco bay. Angel Island was used to deport and detain people coming from China, Japan, India, Thailand, Philippines and all other countries from Asia and South East Asia. Ellis Isla nd which was used as an immigration office for European population was faster in process (Werner 27). There were not many questions asked to the immigrants at Ellis Island and the maximum waiting period was hours to a day. While on Angel Island the conditions were exactly opposite. The detaining period could range from two days to two years. The conditions were deplorable and people staying at Angel Island were reduced to despair and depression. Chinese immigrants

This essay discusses that as a direct result of advances in Information and Communication Technology (ICT) through the internet, citizens have developed a whole new set of expectations regarding the methods and processes used in interacting with their respective governments. Following in the footsteps of the revolution in consumer purchasing that E-commerce established, e government (electronic government) has been stated by studies such as those by Dodd as the new wave of the future in public sector interaction between citizens and government offices for the next generation. e government can be described as the implementation of digital processes and technologies in order to increase efficiency, reliability and coverage of internal and external government services and information sharing to citizens while at the same time implementing a concept known as "lean governance" wherein wasteful spending, processes and methods of operation are in effect eliminated as a direct result of util izing e government procedures and systems. It is based on these perceived benefits that a large number of developed and developing countries around the world have begun to allocate resources towards e government programs and initiatives. In fact, as seen in the article "From e government to Connected Governance" a survey conducted by the United Nations in 2010 showed that 189 out of 192 member states were actually pushing through with a significant amount of e government initiatives.

Web Content Outlier Mining Through Using Web Datasets Research Paper

Web Content Outlier Mining Through Using Web Datasets - Research Paper Example The amount of knowledge sought by an individual is always very specific. Search of specific knowledge from the huge databases and data warehouses has become an essential need. Knowledge seekers while surfing web content on internet, come across large amount of information which is irrelevant to the subject of search and it is generally referred as web content outlier. This research investigates different methods of extracting outliers from web contents. Using web contents as data sets, it is aimed to find an algorithm which extract and mine varying contents of web documents of same category. Structure of HTML is used in this paper with various available techniques to model for mining web content outliers. Web content outlier’s mining using web datasets and finding outlier in them. In this modern time, the information is overloaded with huge databases, data warehouses and websites. The growth of internet and uploading and storing of information in bulk on websites is exponentia l. Accessibility of information is also made very easy for common man through internet and web-browser technology. The structure of web is global, dynamic, and enormous which has made it necessary to have tools for automated tracking and efficient analyzing of web data. This necessity of automated tools has started the development of systems for mining web contents. Extracting data is also referred as knowledge discovery in datasets. The process of discovering patterns which are interesting and useful and the procedures for analyzing and establishing their relationships are described as data mining. Most of the algorithms used today in data mining technology find patterns that are frequent and eliminate those which are rare. These rare patterns are described as noise, nuisance or outliers. (Data mining, 2011) The process of mining data involves three key steps of computation. First step is the process of model-learning. Second step is the model evaluation and the third step is the u se of the model. To clearly understand this division, it is necessary to classify data. (Data mining, 2011) The first step in data mining is the model learning. It is the process in which unique attributes are found about a group of data. The attributes classify the group and based on it an algorithm is built which defines the class of the group and establishes its relationship. Dataset with their attributes known are used to test this algorithm, generally called classifier. Results produced by the classifier assist in determining minimum requirements for accepting data of the known class. It gives the amount of accuracy of the model and if the accuracy is acceptable, the model is used to determine the similarity of each document or data in a dataset. (Data mining, 2011) The second step in data mining is the model evaluation. Techniques used for evaluating the model depend largely on the known attributes of data and knowledge types. The objectives of data users determine the tasks f or data mining and types of analysis. These tasks include Exploratory Data Analysis (EDA), Descriptive Modeling, Predictive Modeling, Discovering Patterns and Rules, and Retrieval by Content. Outliers are generally found through anomaly detection, which is to find instances of data that are unusual and unfit to the established pattern. (Data mining, 2011) Exploratory Data Analysis (EDA) show small data sets interactively and visually in the form of a pie chart or coxcomb plot. Descriptive Modeling is the technique that shows overall data distribution such as density estimation, cluster analysis and segmentation, and dependency modeling. Predictive Modeling uses variables having known values to predict the value of a single unknown variable. Classification

BUS DB4 opening of a presentation is crucial Essay

BUS DB4 opening of a presentation is crucial - Essay Example Objectives should be established from the start.Bring out your personality in the presentation. Make it your own, do not imitate others. When you believe in a topic or concept it is easier to present and also to live by. Maintaining a good balance and keep it interactive will get your opening message across effectively. AIDS presentation: opening was not effective and why Non effective way of opening and presentation: 1. The audience is seated and waiting as the speaker comes rushing in a total frenzy. 2. Does not apologies for being late. 3. Takes at least 10 minutes to get organized. 4. After introducing himself he says "Today you are going to learn all you need to know to protect yourself against HIV infection" a. For the first 15 minutes he waffled on and on, giving statistics and showing overheads about the distribution of the spread of HIV. 5. Then in a "goofy" voice said that condoms should be burned as it just promotes promiscuity. 6. Upon closing he opened the floor for questions, but only answered 4 questions and then said "OK that is it; I hope you all have an HIV free life. Remember true love waits!!" Reasons why Opening and Presentation was ineffective 1. Not prepared 2. Had not done research as to who his audience was going to be relevant to them. 3. Had no idea on how to address teenagers. 4. Had no interaction with the audience. 5. His Opening was only Statistics. 6. He gave information that was totally misleading. 7. There was minimal room for questions. 8. It was more a one-sided opinionated sermon Reference(s) Mary Munter, COPYRIGHT 1998 Meeting Technology: From Low-Tech to High-Tech. Contributors: - author....For example, an Aids presentation to a group of Teenagers, it is essential to touch on basic topics such as self-esteem, peer pressure, social myths, etc. Beginning immediately with statistics and charts you will immediately lose their attention. This can be observed in their body language, i.e. fidgeting, drawing, no eye contact, etc. If you open the presentation with an introduction, statement, story or an interactive game, you will retain the audience throughout the presentation. An interactive game can be used to demonstrate how the HIV virus is spreads instead of just verbally giving facts. High-Tech. Contributors: - author. Journal Title: Business Communication Quarterly.
