3.2 What does a processor look like? So what do these devices that are manufactured in such vast quantities look like? Processors are manufactured as integrated circuits. Essentially they are circuits, around the size of a fingernail, which contain many millions of electronic components manufactured as one very complex circuit. Figure 4(a) shows how a processor manufactured as an integrated circuit is packaged so it can be used as a component in an electronic circuit. The pins of the package are connected to the integrated circu
TALAT Lecture 2101.02: The product development process
This lecture provides a brief introduction to the product development process and systematic design. It aims at generating interest in and a common understanding of the product development process; telling about the basic principles and terminology used in connection with systematic design in order to facilitate the use of the four product design examples presented in this course (see TALAT lectures 2102.01 - .04). The lecture is recommended for those situations, where a brief, general backgrou
1.2 The growth of the legal system The legal system plays a significant and growing role in society as our lives become governed by an increasing number of laws. As our society has become more sophisticated, a greater number of laws have been required. This in turn has resulted in our legal system becoming increasingly more complex. Changes in technology, the way in which we live and the types of relationships we have are all reflected by the law. Society expects the law to reflect its ideas, values and culture, so the law has
3.4 Further exercises (a) Find the angle between each of the pairs of vectors: (3, 1) and (1, −2); i + 2j and −3i + j − 2k. 10.1 Introduction For a variety of reasons, not least the very wide dynamic range of human hearing, the decibel (symbol dB) is often used as a unit for the amplitude of sound waves. The decibel is also used in other contexts, such as specifying the amplification of amplifiers or the degree to which a signal is affected by noise. In the context of sound, the use of the decibel as a unit captures something of the subjective impression of the way loudness changes with amplitude. The decibel unit has Pakistan mob kills woman and girls, over "blasphemous" Facebook post Epidemiology and Biostatistics Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Internet Scout Project Average, Median from the course Introduction to Statistics Average, Median

This course teaches the basic skills needed to critique the medical literature by providing a fundamental understanding of epidemiology and biostatistics. One highlight of the course is the Small Group Session. The small group format provides one with an excellent opportunity to closely interact with a faculty member by enhancing the concepts taught in the lectures and clarifying questions concerning the lecture material.
A recent USGS open file report entitled Ranking of the World's Oil and Gas Provinces by Known Petroleum Volumes groups the worlds 937 geologic provinces into eight regions by known petroleum volumes of field. This site succintly describes the ranking methods used and results of the study. Perhaps not surprisingly, the Middle East and North Africa was found to contain nearly twice as many billions of barrels of oil than any other area. The researchers hope that the rankings will "facilitate studi
The National Snow and Ice Data Center (NSIDC) has released online ice thickness and surface elevation data for the Ross Ice Sheet of Western Antarctica. This data is a result of the Corridor aerogeophysics of the Southeastern Ross Transect Zone (CASERTZ) experiments of the 1990s. According to NSDIC, "the CASERTZ geophysical surveys were aimed at understanding geological controls on ice streams of the West Antarctic Ice Sheet, ultimately to help assess the potential for ice sheet collapse."

Part of the National Center for Education Statistics' Classroom feature, Create a Graph is a simple, visual program in which kids can create a custom bar, area, line or pie graph. Clicking on the graph type from the menu leads to a brief overview about that type of graph, what sorts of data it is useful for, and links to the data entry page. On the data entry page, kids can enter up to 15 data values, type titles, select graph size and colors (12 to choose from), designate .png or .jpeg file typ
The Plymouth State Weather Center offers the latest observations and forecasts for the United States and Southern Canada. By simply selecting a state, individuals can find data on the temperature, wind direction and speed, cloud cover, and other weather information for stations throughout the selected region. The website provides a state forecast as well. The map on the homepage allows users to observe the overall weather patterns throughout the continental United States and Southern Canada.
Presented by the National Earthquake Information Center of the US Geological Survey, the Largest Earthquakes in the US Web site gives visitors information on the location, date, time, and magnitude of the 15 largest earthquakes in the United States and the 15 largest in the contiguous United States. Each link contains a description of the event and the resulting damage, and several, such as the 1964 Prince William Sound, Alaska quake, include isoseismal maps, seismograms, and damage photos of th
Engaging in social issues in today's society requires an understanding of numerical data, statistics, and mathematical assumptions that underlie discussions about the federal budget, the spread of disease and other issues. However, the mathematics and the social issues are often considered in isolation and leave many Americans "ill-prepared to make informed decisions." The Thinking with Data Project is a new initiative of the National Science Foundation, SRI International, Kent State University

From Natural Resources Canada comes the National Earthquake Hazards Program Web site. Those interested in earthquakes in general or specifically about physical science topics in Canada will appreciate the many informational offerings on the site. Readers can learn about historical earthquakes in Canada and how frequent they are, find out how earthquake hazards are evaluated, how to survive an earthquake, earthquake research in Canada, and much more. The Products and Publications link contains se
Antarctic monthly mean sea surface temperature and pressure data are accessible online from the Carbon Dioxide Information Analysis Center (CDIAC) of Oak Ridge, TN. Compiled by the Climatic Research Unit of the University of East Anglia, UK, this data is an update of temperature. and pressure data collected between 1957-1990 from 29 stations over Antarctica. CDIAC's Web page of this climatic research project displays a map of sampling localities and a table of contents, guiding readers to figure
The latest Energy Outlook report was released in late December by the Department of Energy, looking at key factors of change over the last year and offers projections of change to 2020. The report contains specific information on energy issues, prices, use, production, and more, including graphs and tables (when applicable) that relate to the nation as well as specific regions.
This course covers population and variables; Standard measures of location, spread and association; Normal approximation; Regression. Probability and sampling: Binomial distribution. Interval estimation; Some standard significance tests.
