Internet Scout Project
A great offering from the nonprofit technical and educational organization Water Environment Federation is the Be in the Know...Get With the Flow activity. Using Flash technology, users get to experience an interactive and graphically interesting Web site that shows how water moves from homes and businesses to water treatment facilities and finally back to rivers and lakes. When various parts of the system are clicked, a new page is brought up that contains an animation such as the sewer system
Quelle est la nature des expériences vécues par les étudiants en Travaux Pratiques : analyse de d
Le but de cet article est de faire le lien entre les expériences vécues par des étudiants durant les TP et les activités conçues et décrites par lenseignant. Nous tentons donc de déduire la nature des expériences dapprentissage vécues par les étudiants en TP, à partir du discours des enseignants sur ce quils font et ce quils demandent aux étudiants de faire. Nous introduisons un cadre théorique que nous utilisons pour caractériser des Travaux Pratiques : selon leurs buts et
Self-directed learning in simulation-based discovery environments
SIMQUEST1 is an authoring system for designing and creating simulation-based learn-ing environments. The special character of SIMQUEST learning environments is that they include cognitive support for learners which means that they provide learners with support in the discovery process. In SIMQUEST learning environments we try to find the balance between direct guidance of the learning process and sufficient free-dom for learners to regulate the learning process themselves. In this article we de-
Students' adaptation to a new situation:
the design of an experimental procedure
Different studies (Arce and Betancourt, 1997; Séré, 2002) emphasize the importance of the task of experimental procedure design in a learning context. However, the required design is a difficult task for students (Séré and Beney, 1997). Consequently, students are hardly ever allowed to design their own experiment. The study by Tiberghien et al. (2001) showed that to learn how to plan an investigation in order to address a specific question or problem was the least frequent process object
Adaptive FIR Filtering
In this laboratory, students implement a real-time adaptive FIR filter, investigate the convergence of the least mean squares (LMS) algorithm, and apply the adaptive filter to the problems of system identification and echo cancellation.
Adaptive Filtering: LMS Algorithm
This module introduces adaptive filters through the example of system identification using the LMS algorithm. The adaptive filter adjusts its coefficients to minimize the mean-square error between its output and that of an unknown system.
Directory of Open Access Journals
Directory of Open Access Journals. This service covers free, full text, quality controlled scientific and scholarly journals. We aim to cover all subjects and languages. There are now 1964 journals in the directory. Currently 482 journals are searchable at article level. As of today 81975 articles are included in the DOAJ service. The aim of the Directory of Open Access Journals is to increase the visibility and ease of use of open access scientific and scholarly journals thereby promoting thei
3.2 - Clock System on the ez430
Describes how the clock system works on the ez430.
Introduction to Synchronous Digital Systems - Part II Fall 2007
Machine Structures - Fall 2007. The CS61 series is an introduction to computer science, with particular emphasis on software and on machines from a programmer's point of view. The first two courses considered programming at a high level of abstraction, introducing a range of programming paradigms and common techniques. This course, the last in the series, concentrates on machines and how they carry out the programs you write. The main topics of CS61C involve the low-level system software and th
African Americans and the United States judicial system
Harvard law professor Alan Dershowitz comments on the inability for Black Americans to receive fair treatment in the United States judicial system.
Dr. Carol Miller - Academic Spotlight
Dr. Carol Miller, distinguished professor of business law, was recently selected as the recipient of the Women's Justice Legal Scholar award. The award is presented by the Missouri Lawyer's Weekly Media. The Legal Scholar award is awarded to women faculty members or administrators who have fulfilled the women's justice ideals through their own work with the justice system through their research or scholarship, or through teaching and inspiring others. The award recognizes women across Missouri

Parts of a Corn Seedling
This illustrated guide to a corn seedling (Zea mays, Monocotyledon) is designed to help students recognize and learn the plant's individual parts. Along with an explanation of monocotyledon embryos, it includes a short description of the root system and coleoptile.
This site features Flash animations that illustrate how the Global Positioning System (GPS) works. The animations depict how GPS signals are derived, compare geostationary and polar orbits, and explain satellites, ground control, and user segments, which comprise the three main GPS components. These resources are suitable for use in lectures, labs, or other teaching activities.
This animation shows how velocity and position of an aircraft are resolved in a 3-D Cartesian coordinate system.
American Visionaries: Thomas Moran
features paintings and sketches of the noted American landscape painter. Moran's pencil and watercolor field sketches and paintings captured the grandeur and documented the extraordinary terrain and natural features of the Yellowstone region. His artwork was presented to members of Congress by park proponents and helped inspire Congress to establish the National Park System in 1916.
Allegheny Portage Railroad: Developing Transportation Technology
shows the innovative transportation system used in the 1820s-1840s to tow railroad cars up and down the steep slopes of the Allegheny Mountains.
Can Public Health Researchers and Agencies Reconcile the Push From Funding Bodies and the Pull From
Responding to growing impatience with the limited application of research findings to health practices and policies, both funding bodies and communities are demanding that research show greater sensitivity to communities’ perceptions, needs, and unique circumstances. One way to assure this is to employ participatory research—to engage communities at least in formulating research questions and interpreting and applying research findings and possibly also in selecting methods and analyzing dat
Enhancing Physics Knowledge for Teaching – Maxwell’s Equations
In this session we’re going to look at how electricity and magnetism can be unified into a system of equations, named after James Clerk Maxwell, the Scottish physicist who first proposed them. Then we’ll see how this leads to an understanding of the nature of electromagnetic radiation.
Lessons from Hurricane Katrina: Can We Save California's Delta?
Lessons from Hurricane Katrina: Can we save California's Delta? Raymond B. Seed, Professor of GeoEngineering, Department of Civil & Environmental Engineering The catastrophic flooding of New Orleans during hurricane Katrina was the single most costly failure of an engineered system in history. It was also a social and cultural tragedy of unprecedented peacetime proportions for the United States. After the disaster, a team of leading experts from across the country examined the engineering and
