Internet Scout Project
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
Royal Botanical Gardens-Orchid Society: Growing Orchids
Hosted by the Orchid Society of Royal Botanical Gardens in Canada, this website features an introduction to growing orchids by Tony Capon of the Kingston Orchid Society. Accompanied by small, but beautiful images of orchids the article includes sections on Light, Water, Fertilizer, Temperature, and more. This site provides links to a nice site on the Native Orchids of Canada, and to information about the Orchid Society of Royal Botanical Gardens. A page of relevant links is offered as well.
Internet Scout Project
The Natural Resources Conservation Service provides an array of materials to assist people with their understanding of soils. Through an online presentation, users can learn ten key points about soil characteristics and their importance. Teachers and students can find many fun activities including soil erosion and particle size demonstrations and soil songs. The website provides a great introduction to soil formation and classification. Those contemplating a career in soil science can discover t

Mathematics for Computer Science
A basic introduction to Calculus and Linear Algebra. The goal is to make students mathematically literate in preparation for studying a scientific/engineering discipline. The first week covers differential calculus: graphing functions, limits, derivatives, and applying differentiation to real-world problems, such as maximization and rates of change. The second week covers integral calculus: sums, integration, areas under curves and computing volumes. This is not meant to be a comprehensive calcu
Database Management Systems
A more formal approach to Relational Database Management Systems, compared the way they were covered during Web Applications. Database systems are discussed from the physical layer of B-trees and file servers to the abstract layer of relational design. Also includes alternative and generic approaches to database design and database management system including relational, object-relational, and object-oriented systems, SQL standards, algebraic query languages, integrity constraints, triggers, fun
Science in Focus: Force in Motion: Workshop 6: "Force Against Force"
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the force of gravity. A magnet placed in a cup on one side of a pan-balance is stuck to a stationary magnet beneath the cup. When enough washers are placed on the opposite side of the balance, the magnets will separate. Graphical analysis shows some unexpect
RobertNiles.com: Statistics Every Writer Should Know
Robert Niles, a journalist and producer for the LA Times, created this site to help other writers learn the basics of statistics. He explains many key concepts that are essential to report accurate, meaningful numbers and facts. After starting with the fundamentals of mean, median, and percent, Niles goes on to describe more advanced topics like normal distribution, margin of error, and data analysis. For each section, an example or two are provided to demonstrate proper usage of the techniques.
Science in Focus: Force and Motion: Workshop 8. Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force constant or stretchiness of the spring. Lecture demonstrations using student volunteers help to illustrate that even rigid objects be
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
Vers une nouvelle interface de lecture pour des forums de discussion dédiés à des élaborations c
Dans le cadre de l'apprentissage collaboratif assisté par ordinateur (ACAO ou CSCL), les forums de discussion occupent une place centrale. Si de multiples recherches leur sont consacrées, elles se centrent pour l'essentiel soit sur des méthodes d'analyse a posteriori du contenu, de la dynamique des échanges et des réseaux sociaux, soit sur le calcul d'indices de participation, éventuellement présentés aux participants en cours d'activité. Suite à un symposium de recherche, organisé à
Logic and Proofs is an introduction to modern symbolic logic. It provides a rigorous presentation of the syntax and semantics of sentential and predicate logic. However, the distinctive emphasis is on strategic argumentation. Students learn effective strategies for constructing natural deduction proofs. This learning is supported by the Carnegie Proof Lab: it provides a sophisticated interface, in which students can give arguments by strategically guided forward and backward steps.
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C
Doris Chase: Artist in Motion
In this 1991 program, the late Doris Chase discusses her work as a painter, sculpter, and video artist. Chase is best remembered as a pioneer in using computer imaging to manipulate video images to create dreamlike, colorful works. Examples of her work, including the acclaimed "Circles II" and snippets from the "By Herself: Table for One" series are shown, with artist commentary.
TALAT Lecture 3207: Solidification Defects in Castings
This lecture provides an introduction to the causes and remedies of the main solidification defects in castings. The students should be able to diagnose the major defects in castings and propose methods of preventing them. Basic knowledge of physics and foundry practice is assumed.
TALAT Lecture 3202: The Liquid Metal
This lecture provides an introduction to factors affecting the quality of molten aluminium. Basic knowledge of foundry practice is assumed. The student should be able to appreciate the differences between good and bad melting practices in a foundry.
Risk Management for Enterprises and Individuals
This book is intended for the Risk Management and Insurance course where Risk Management is emphasized. When we think of large risks, we often think in terms of natural hazards such as hurricanes, earthquakes or tornadoes Perhaps man-made disasters come to mind such as the terrorist attacks in the U.S. on September 11, 2001. Typically we have overlooked financial crises, such as the credit crisis of 2008. However, these types of man-made disasters have the potential to devastate the global mark

This lecture is an introduction to aluminium alloys, fabrication methods and properties. It provides information about the classification of aluminium alloys, new alloys and composites; shaping processes, processing chains and component shapes; microstructure and the interaction between microstructure and properties. It promotes understanding of the fact that the correct choice of materials demands knowledge of alloys, shaping processes and microstructure and the interaction among them. The lect
