The shapememory effect and superelasticity property of NiTi fascinate people, but actually requiresignificant materials knowledge to fully understand the phenomena. A laboratory dealing withphase transformations was thus developed to capitalize on the allure of NiTi for a junior/seniorlevel

The students participate on workshops applying scientific and engineeringconcepts, as well as on hands-on experiments in a laboratory environment.One of the most popular workshops in EXITE! is the construction of an electronicdoorbell for the girls’ bedrooms. Girls at this age begin to ask for respect from theirparents when they want to go into their rooms, and most of girls see the doorbell as themean to manage this need. This motivates the participants to be interested in theworkshop.The construction of the electronic doorbell introduces the participants the basics conceptsof electricity, circuits, types of

Students must use an on-campus computer laboratory to access the software. One teaching assistantis assigned to an ECF laboratory, on a weekly basis. Students are required to submit their completedassignments electronically, to a specified folder within the ECF network.Conclusion The use of enhanced visual aids in lectures as well as a computer laboratory has enriched thelearning of the students. The VRML computer models used here can illustrate a mechanical conceptwithin minutes, that would otherwise require the disassembly of a physical device, which isgenerally impractical during a lecture.

The methods include teamwork, class/group discussion, peertutoring/teaching, and problem solving skills. In each activity, students can be a learner or can bea teacher, to lead or to be led. It creates interaction between teacher and students. The hands-onlaboratory courses reinforce the basic concepts that the students have learned from the lectures.To enhance the students’ laboratory experiences, computer-based design software has been usedin the measurement and the design process.

Throughout the history of the gas turbine one of the most interestingfeatures has been the theoretical ability for them to use a variety of fuels. Some earlyauthors even anticipated performance independent of fuel type. In the extreme, Tickell [2]reports applications for piston engines using used cooking oil ’straight’, after a startupperiod with conventional fuel. Commercial airplane engines do not have the liberty of using compounded vegetablefuels, due mainly to their auxiliary equipment, temperatures and pressures, standards andguaranteed performance, Mattingly [5].

Thus the SUCCEED Coalition embarked on a set of experiments in 1992 toexplore different approaches to integrate the freshman year.Coupling subject integration in the first year with an introduction to engineering was ideally suitedfor the Coalition’s program given the large resources required to conduct large-scale experiments,the availability of a multiple-campus laboratory to determine robustness, the extended period offunding, and the visibility of this NSF program. The approaches to integration studied by thecoalitions required building teams of faculty from multiple disciplines and assessment experts toevaluate the program impact and designing and

A variety of standard and non-standard codes are also provided so that the usercan tailor the code to operate most new machine tools.The significance of this project is that the generality and modularity of the post-processor lendsitself to utilization in similar laboratories at other educational facilities.Introduction and Problem StatementA CNC code

The “manager” (instructor) also explained howvital the success of this project was to the company. Students were encouraged to find allnecessary information at the initial meeting (typical of situations they may face after graduation)since “designers” could only contact the “customer” with their “manager’s” agreement after themeeting.
