Take a constant speedconveyor belt industrial application as an example: A DC motor can be used to configure asystem that can meet the specification. To achieve the objective of the speed control, either aPulse Width Modulated full bridge DC to DC converter [1] or a controlled rectifier circuit can beused to drive the DC motor. By choosing different circuits, students need to understand whatother peripherals associated with the chosen circuits are needed in order to make the whole Page 4.423.1system work.

Preparation could be accomplished in a spring and asummer. For Criteria 2000, however, some non-traditional expectations have been added whichmake the preparation for a visit a bit more demanding. That preparation may now require severalyears and should be considered to be a continuous process. Preparation for the visit falls into seven broad categories:1.

Following the outline of the selected book proved to be very frustrating, so a differentstrategy was adopted that would encourage students to use books, proceedings, journals and otherdocuments available on campus. To assure a steady flow of information, students were requestedto make a weekly reports on their findings and the instructor presented the summaries of thesereports in class followed by weekly short quizzes (see Table 1.).During the first weeks of the course students were allowed to choose freely the topics using theexcellent examples

However, their skills are often underutilizedand unrecognized by faculty. We strongly suggest that you consider including them in yourresearch projects for a number of reasons:1. Typically young students are very knowledgeable about computers. You can initially involve them in your research by letting them develop or maintain the research group’s web page. Web page maintenance will expose the undergraduate students to your research as well as the other students in your research group. As a result, the student may decide to get more involved

In product design, QFD relates the product performance requirements ofthe customer with technical design characteristics through a matrix generally known as the“house of quality.” This “house of quality” maps “whats” (product / customer specifications) to“hows” (technological features) and develops a quantitative measure of priority for eachtechnical characteristic based on its impact on the customer requirements. Based on this abilityto identify relationships, QFD is an attractive decision tool for application to the problem ofcareer development.

rectifiers operate.[1]Nonetheless, seeing such a circuit in operation often helps the student understand how it works.Complicated or unfamiliar instrumentation can slow the learning down, but a working circuit withsimple visual impact can dramatically enhance understanding. In this paper, a simple demonstration using a working rectifier helps introduce the circuit'soperation to the student. The circuit is intended as introductory, with flashing lights to illustrateimportant points. The circuit is portable and construction is well within the capability of anundergraduate electrical engineering program, requiring just a small piece of circuit board and asimple function generator.
