Hsieh1 described a need tobetter understand how engineers develop expertise in automated system integration and to designhigh quality educational curricula that will equip students with the necessary skill sets.Education in system integration and robotic workcell design is typically accomplished via acapstone course or senior design project2. In this type of instruction, students are expected tolearn by doing, and learning outcomes may vary depending on the type and difficulty of theselected projects. Another approach is to create an interdisciplinary course, such as

The system uses a typical vapor compression Page 11.461.2cycle with R-134a as the refrigerant. For the compressor, a Seltec TM-08 unit was used. Thiscompressor is commonly used in automotive applications. It is powered by a 3 hp three-phaseelectric motor that is operated by a frequency controller. Trunion bearings support the motor,which is connected to a load cell for measuring the torque applied to the compressor. Heatrejection is accomplished through a coaxial condenser manufactured by Edwards Engineering.Cold water from the

However,young women are not choosing technical careers at the same rate as young men. Forengineering, it has been around 20% for several years. Numerous programs designed between1993 and 2003 to increase the woman enrichment in engineering did not make any fundamentalchange. There is no discovery of any convincing explanation or one to two useful remedies. If itis not the lack of programs, websites, goodwill, research, or budget that failing us, it must besome thing else.

It is a three-credit hourclass with three 1-hour lectures per week. This paper describes the development of a web-basesolver for compressible flows using Java programming language. The main goal of the solver isto provide students with a software tool that can be used in the compressible flow course.

thrust of this project is to provide students with an additional tool to understand andvisualize mathematically complex concepts covered in a typical engineering mechanics-Staticscourse, which will enhance their learning and understanding of this subject. This tool will also beavailable for all subsequent courses that need Statics background. Inadequate knowledge ofStatics, negatively influence the learning and teaching of these subjects as considerable timemust be devoted to review the Statics part. Courses like Strength of Materials, Machine Design,and structural design are examples of subjects that depend primarily in excelling Statics.

Several measures ofsatisfaction from the teaching evaluations are shown in Table 2. The rating of the“Textbook/supplementary material” increased in the experimental sections, even though the sametextbook was used, as did that of “laboratory assignments/projects.” There is no actuallaboratory for the course, so the responses in the experimental section are believed to relate tothe spreadsheet exercises.

Projections on workforce needs in the next decade suggest a need to tap all available resources and the most obvious untapped resource for U.S. engineering is the underrepresented groups – including women and minorities. Women and minorities do not see engineering as an opportunity for themselves because the “face” of engineering does not look like them and, furthermore, they have little first-hand knowledge of what the engineering profession is all about. Because leaders are often the most visible role models to the world for the university or company, diverse leaders are needed as role models to attract girls, young women and underrepresented men to engineering.

Typically, their design projects (with students workingin groups of three) involve designing a machine to perform a particular task. Through thesynthesis stage of developing the machine’s layout and configuration, followed by force analysisand kinematic analysis, students often just try to get “something that works.” During advisingsessions, they are encouraged to look at a graphical analysis approach to check their results.Many times this can be an epiphany to the students when they visually
