A supplementary board that monitors “six inputs—twothermometer calibration voltages, three single ended DC voltages, and one temperaturedependent differential voltage—and displays them one at a time on a three and one-half digitdisplay” was introduced by Aubrey and Brelage in 1995.4 It functions as a temperature andvoltage monitor for the rest of ALFRED. Hundreds of students have developed theirtroubleshooting skills to the point where they are able to locate and repair multiple faults at thecomponent level in a complex electronic system.

Variable Figure 1. The “Helicopter”1 First, we derive the math model for the students, mainly sophomores that haven’t had anaerodynamics course yet. Then, using the three design variables listed above, and the mathmodel, we find values of the design parameters which maximize the descent time. The studentsin the class at Virginia Tech used the solver in Excel to find the optimum values of the designparameters. Next, we built the optimum design found in Excel and tested it. Working around the optimum as a baseline, we used design of experiments theory todevelop a matrix of designs for the experimental development program. Each team built thematrix of designs and then tested them. They then used the results

In addition, Cal Poly students have received the California GeotechnicalEngineers Association (CGEA) annual Outstanding Graduating Senior Award four of the pasteight years (1990, 1991, 1992, and 1995).Undergraduate CEEN students are required to take one course and one laboratory in basicgeotechnical analysis. A student interested in geotechnical engineering may then choose fromeight geotechnical engineering electives offered by the department (Table 1). Shallow and deepfoundation design, slope stability analysis, geotechnical earthquake engineering, and earthpressure theory are among the topics covered in the elective courses.

However, by the mid-1980s the ever-increasing availability, the user-friendliness, and the utility of engineering applications software portended a shift in theengineering workplace to less programming and more reliance on commercial software elements.In the 1990s that trend has continued, and, paraphrasing Baker (1) at the University of Tennessee,the days of amateur programming in the engineering workplace are over.

Though there has been some utilization of3-dimensional (3-D) modeling software since the early 1990’s 1, 2, the technology was still beingused primarily as a vehicle for the static documentation of individual parts.

The motivationfor this paper stems from the thorough conviction that chemical reactivity together withinfluencing factors serve as the basis for a substance to be considered a potential hazard. Hazardis defined as a chemical or physical condition that has the potential for causing damage to people,property, or the environment [ 1 ]. The nature and state of a substance have a direct bearing onits reactivity. Other factors that promote chemical reactivity include, buoyancy effects, heat andmass transport, wind velocity, weather condition, pressure, temperature, catalysis, and chemicalcompatibility during storage and transportation.
