simultaneous engineering,a focus which echoes long-standing themes in product development practices.1’lz Nevertheless, presentingthese ideas in undergraduate engineering education calls for a departure from the usual content and pedagogicalapproaches. The goal of this paper is to describe the development of a new course in concurrent engineering.Teaching concepts in product development benefits greatly from a hands-on approach. We have attempted toestablish this goal in three ways: by developing and using a number of laboratories and demonstrations, byinviting speakers from industry who can make classroom lessons concrete, and by using cases as the basis forclass discussion. This paper includes a discussion of the curriculum, of existing

result, we have decided to provide thedesign team a pre-fabricated mobile robot platform made by AK Peters Corporation[1]. The platform includesthe robot body, wheels, two motors and gear boxes1. We believe this will help them avoid spending too muchtime designing and revising the robot body. Fig. 1 shows a sketch of the robot the design team is currentlyworking on. A caster wheel is attached at the back of the platform to provide stability of the robot system. Theactual senior design project took place during the Spring/96 semester. As a final project of another lab class,however, the project team had completed the initial part of the senior project. Since the goal of this project is to create a mobile robot with navigational

Credit Hours Reduction In Florida over the past several years, the legislature, Board of Regents, and universities have worked ona variety of programs to improve the efficiency and accountability of university education. The most recentmeasurement shows that an average student in Florida’s public universities take, about 24 credit hours beyondthose required of a final degree. 1 A reasonable balance between the student’s need for education exploration and the state’s need forgreater access for all its citizens to higher education gives the student extra hours up to 10VO of those requiredfor their degree at the state’s expense. The cost of “excess” hours beyond 10% will become the responsibility ofstudents and universities. In

In the 1995 class of 24 students, we created four teams of six students each, meetingduring two different lab times (three hours per week). Ideally, the teams should have a maximum of fourstudents4, however limitations in laboratory facilities required us to limit the number of teams. In the 1996class, we limited class size to 20 students, comprising five-member teams. The smaller team size is definitelymore tractable in the laboratory setting. The teams are assembled to be as heterogeneous as possible, from thepoint of view of diversity in knowledge and work experience. Name, Academic Major Address, Phone Number

The sine wave test consists of displaying a sinusoid from a function generator on an FFTSpectrum Analyzer. Results are verified by observing the same signal on an oscilloscope and comparingthe frequencies and amplitudes reported by the function generator, analyzer and scope. In generalthis simple verification is not possible with complicated signals. The computer-based FFT analysis simulates a situation where data are stored on disk or tapeand are later fed to a computer program for Fourier analysis.

The analysis performed was fairlystraight-forward: the mean of each question was computed on a five-point scale (with "5" → "strongly agree"and "1" → "strongly disagree"), and from equally weighted arithmetic averages of several of these means, threecomposite scores were computed: (1) an "instructor" score, (2) a "course" score, and (3) a "facilities" score.Associated with each composite score was a "percentile".

This is especially true in theaerospace field. Hoist et. al.

Sincefasteners overwhelmed the weight of the other structural members, the weight of the fasteners wassubtracted from the total weight to determine the truss structures’ weight for all efficiency calculations.
