Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title '' Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limpopo
Limpopo is the northernmost province of South Africa. It is named after the Limpopo River, which forms the province's western and northern borders. The capital and largest city in the province is Polokwane, while the provincial legislature is situated in Lebowakgomo. The province is made up of 3 former homelands of Lebowa, Gazankulu and Venda and the former parts of the Transvaal province. The Limpopo province was established as one of the new nine provinces after South Africa's first democratic election on the 27th of April 1994. The province's name was first "Northern Transvaal", later changed to "Northern Province" on the 28th of June 1995, together with two other provinces. The name was later changed again in 2002 to the Limpopo province. Limpopo is made up of 3 main ethnic groups namely; Pedi people, Tsonga and Venda people. Traditional leaders and chiefs still form a strong backbone of the province's political landscape. Established in terms of the Limpopo House of Tra ...

Computer Scientist
A computer scientist is a person who is trained in the academic study of computer science. Computer scientists typically work on the theoretical side of computation, as opposed to the hardware side on which computer engineers mainly focus (although there is overlap). Although computer scientists can also focus their work and research on specific areas (such as algorithm and data structure development and design, software engineering, information theory, database theory, computational complexity theory, numerical analysis, programming language theory, computer graphics, and computer vision), their foundation is the theoretical study of computing from which these other fields derive. A primary goal of computer scientists is to develop or validate models, often mathematical, to describe the properties of computational systems ( processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discoverin ...

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a thorough petition, review, and election process. The academy's quarterly journal, '' Dædalus'', is published by MIT Press on behalf of the academy. The academy also conducts multidisciplinary public policy research. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commerc ...

Order Of Mapungubwe
The Order of Mapungubwe is South Africa's highest honour. It was instituted on 6 December 2002, and is granted by the President of South Africa, for achievements in the international arena which have served South Africa's interests. The order originally had three classes, and was enlarged to four in 2004: * Platinum (OMP), for exceptional and unique achievements * Gold (OMG), for exceptional achievements * Silver (OMS), for excellent achievements * Bronze (OMB), for outstanding achievements. The order is named after Mapungubwe, an ancient African nation which existed a thousand years ago in what is now the northern part of the Limpopo province. The first recipient of the order (in the Platinum class) was the late former president Nelson Mandela. Design The badge is a horizontal oval above an inverted trapezium. Inside the oval frame is depicted a golden rhinoceros with the sun rising above Mapungubwe Hill in the background. The convex upper edge of the trapezium is decorated wit ...

Finite Element Updating
Finite element model updating is the process of ensuring that finite element analysis results in models that better reflect the measured data than the initial models. It is part of verification and validation of numerical models. The process The process is conducted by first choosing the domain in which data is presented. The domains used include time domain, frequency domain, modal domain, and time-frequency domain. The second step is to determine which parts of the initial models are thought to have been modeled incorrectly. The third task is to formulate a function which has the parameters that are expected to be design variables, and which represents the distance between the ''measured'' data and the finite element model ''predicted'' data. The fourth step is to implement the optimization method to identify parameters that minimize this function. In most cases, a gradient-based optimization strategy will be used. For nonlinear analysis, more specific methods like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis Turning Point
The Lewis turning point is a situation in economic development where surplus rural labor is fully absorbed into the manufacturing sector. This typically causes agricultural and unskilled industrial real wages to rise. The term is named after economist W. Arthur Lewis. Shortly after the Lewis point, an economy requires balanced growth policies. Typically, reaching the Lewis turning point causes an increase in the wage bill and the functional distribution favoring labor. However, in some cases such as in Japan from 1870 to 1920, agricultural labor productivity increased significantly and produced a labor surplus, dampening the rise in real wages. According to a study by Zhang and Yang, China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ... reached the Lewis point in 2010; cheap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efficient Market Hypothesis
The efficient-market hypothesis (EMH) is a hypothesis in financial economics that states that asset prices reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information. Because the EMH is formulated in terms of risk adjustment, it only makes testable predictions when coupled with a particular model of risk. As a result, research in financial economics since at least the 1990s has focused on market anomalies, that is, deviations from specific models of risk. The idea that financial market returns are difficult to predict goes back to Bachelier, Mandelbrot, and Samuelson, but is closely associated with Eugene Fama, in part due to his influential 1970 review of the theoretical and empirical research. The EMH provides the basic logic for modern risk-based theories of asset prices, and frameworks such as consumption-based asset pricing and inte ...
