How Do Satellites Work?
This 5:57 uses narration and graphics to help show how communications satellites work. The video does an excellent job of showing how these impact cell phones and television and other media.
Robust source-seeking hybrid controllers for nonholonomic vehicles (experiment)
This video shows an experiment involving a mobile robot, an IR-camera vision system, and a wireless network. The robot queries the vision system for position information. The robot uses this position information to simulate a potential function in its environment. The hybrid controller uses these measurements in a coordination of vehicle steering and an optimization algorithm to drive the vehicle to the minimum of the function (shown as a blue 'x').
Stability of response characteristics of a Delphi panel: application of bootstrap data expansion
Background Delphi surveys with panels of experts in a particular area of interest have been widely utilized in the fields of clinical medicine, nursing practice, medical education and health care services. Despite this wide applicability of the Delphi methodology, there is no clear identification of what constitutes a sufficient number of Delphi survey participants to ensure stability of results. Methods The study analyzed the response characteristics from the first round of a Delphi survey con
Learning to describe, classify, and differentiate similar animals
In nature, many animals look very similar. It is important to be able to describe animals and differentiate them from other animals. Consider several rodents.
Ferns, poison oak, and an unknown hairy plant on the forest floor
Poison oak and the unknown hairy plant are similar, not in appearance, but because they both have characteristics that deter predators. The three leaflets of poison oak distinguish the plant as poisonous. The hair on hairy plants, on the other hand, is unattractive to insects for food.
Do Materials Get Tired? Creep
This video explains that materials will deform slowly or “creep” under the right conditions, when constant force is applied. “Strain” is illustrated with rubber bands and we learn that engineers can calculate creep strain as a function of time.

Seeing and Feeling Sound Vibrations
Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use this knowledge to discuss how engineers study sound waves to help people who cannot hear or talk.
Corn for Fuel?!
In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of

Program 6: Radix-2, DIT, One Butterfly FFT
This is a Fortran code for a simple Decimation-in-Time, Radix-2, one butterfly Cooley-Tukey FFT preceeded by a bit-reversing scrambler.
ART 319-01, Roman Art and Architecture, Spring 2006
This course will survey the main periods and works of Roman art and architecture, employing a variety of interpretative strategies to the works. The goal of this study is to gain a better understanding of what motivated Roman artistic production and how the ancient Romans interpreted and used those works.,This syllabus was submitted to the Rhodes College Office of Academic Affairs by the course instructor.
In this unit, you will be hearing and reading about the issues faced by people living in poverty in Britain in 2000. This is intended to give you an understanding of what poverty is like from the perspective of the people themselves, both in terms of the experience of living on a very low income, and some of the effects this has had on their lives. One of the biggest problems facing people living on a very low income is how to afford adequate heating.
