Surface Irrigation Design
This course was originally developed for the United States Department of Agriculture. It contains nearly 20 video lecture presentations with accompanying slides in English, Arabic, and French, an online textbook, homework assignments, and downloadable surface irrigation simulation software also developed by Dr. Walker. This course highlights design and evaluation of surface irrigation systems, field measurements for evaluating and improving uniformity and efficiency, simulation of surface system
Information theory explores the fundamental limits of the representation and transmission of information. We will focus on the definition and implications of (information) entropy, the source coding theorem, and the channel coding theorem. These concepts provide a vital background for researchers in the areas of data compression, signal processing, controls, and pattern recognition.
Changes in Ecosystems - by StudyJams
Ecosystems are constantly going through gradual changes. Sometimes those changes are natural, and sometimes they are caused by humans. Learn more about changes in an ecosystem with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
Photonic Dipole Contours of Ferrofluid Hele-Shaw Cell (Basic Video)
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. "15 sets of sequenced red, yellow, and green LED’s around the

"Quantum Optical Communication, Fall 2008"
" This course is offered to graduate students and covers topics in five major areas of quantum optical communication: quantum optics, single-mode and two-mode quantum systems, multi-mode quantum systems, nonlinear optics, and quantum systems theory. Specific topics include the following: Dirac notation quantum mechanics; harmonic oscillator quantization; number states, coherent states, and squeezed states; P-representation and classical fields; direct, homodyne, and heterodyne detection; linear
Do Materials Get Tired? Fatigue
This video explains how the strength of a material can be measured in the laboratory and used to design structures, like bikes, airplanes, and even chairs. We see a controlled lab experiment that applies precise force to a paper clip until it breaks.

The Human Body by StudyJams
The human body is an incredible, complex system built with different cells. Similar cells get together to form tissue, like muscle tissue. All of these tissues form the organisms that keep everything running smoothly in the body. Learn more about the human body with this slide show from StudyJams. Vibrant images are set to music with information written under each photo. A short, self-checking quiz is also included in this link.
