This paper briefly describes the course, presents the experiments, andshows how students were exposed to a wide range of concepts and applications.Diagrams are shown and described, as necessary.I. IntroductionCourses that teach microprocessors and microcontrollers are found in most engineeringand engineering technology curricula. Typically, two or more courses are used to coverthe various aspects of microprocessors and microcontrollers [1-7]. In the ControlSystems Engineering Technology program at Texas A&M University-Corpus Christi(A&M-CC), however, the curriculum has only one course devoted to this area. Our goalis to introduce students to the practical aspects of microprocessors and

In theElectronics Engineering Technology program at BYU students complete an experiment in thedesign and test of transistor amplifiers at frequencies above 1 GHz. The objective of theexperiment is to give students the background they need to be familiar with the problems andmethods of high frequency circuits they will encounter in industry.

The only solution can be the engineer’s inherent andperhaps continuously trained confidence and self-awareness (the goal of moral autonomyas cited by Messrs. Martin and Schinzinger, ref.1) to derive a solution to the problemeven as the deficiency of the engineering solution is uncovered. The ethical engineermust be thus understanding of his/her potential for error but more strongly aware ofhis/her competence to resolve these errors either individually or with the qualifiedassistance of others.The most striking example of this empowerment is the story of the structural engineer,Mr. William LeMessurier as told in

Thus, in additionto the necessity of dissipating the latent heat of fusion, solidification of an alloy involves theredistribution of solute as well. Therefore, the solidification of an alloy involves both heat transferand mass transfer, and it is important to understand their roles in the solidification of a fusionweld.Solidification MechanicsIn the production of a fusion weld, a molten weld pool is established and, through control of theprocess variables, is made to travel at a constant rate without significantly changing its shape.Figure 1 is a schematic representation of an elliptical weld pool with a

This simultaneous increase in fatigue and strength properties of microalloysteels makes them potential materials for various engineering applications.1.

is an outstanding opportunity to reinforce basic knowledge that the studentshave acquired from Statics through our senior-level course, Machine Design. Starting atthe most basic level, Statics, students are reminded that unless they satisfy theequilibrium equations their model will not work. Beam-type models can be used tovividly illustrate stress distributions in beams whether under torsion or bending. Thestudents can model stress concentrations, Figure 1, and calculate their own stressconcentration factor.

In order to increase this low rate of success, institutions must look fornovel methods to encourage students to persist in their pursuit of a degree. One method thatengages students academically and socially is the undergraduate research experience.Undergraduate research activities are known to promote goal setting and planning beyondgraduation, thus affecting student retention.2The affinity group model, being implemented at the University of Texas at El Paso’s Departmentof Electrical and Computer Engineering, is more far-reaching than the usual research group.
