In the mid-80’s theDepartment of Industrial Engineering (IE) joined the course so that project teams werecomposed of both ME and IE students, but the relative sizes of the Departments (annualgraduations rates of about 60 BSME and 10 to15 BSIE) and the nature of the projects(mostly ME in nature with only a few in IE) prevented an interdisciplinary experience forall design teams.

The plan, which is directed at closing educational gaps withinTexas, as well as between Texas and other states, has four goals: to close the gaps in studentparticipation, student success, excellence, and research. The plan includes strategies for reachingeach of the goals and an annual performance measuring system. One outcome of this plan was ademonstrated need for engineering education and an outcome of this was the creation of the non-profit membership organization known as the Texas Engineering and Technical Consortium(TETC).

Thefield of Electrical Engineering is a very challenging subject for most students, and isoften perceived as too difficult. It was also observed that the retention rate was very poorfor these students in their freshman and sophomore years. With the help of IEEEOfficers and graduate as well as undergraduate students, the IEEE mentoring office wascreated. The IEEE mentoring office provides help to engineering students with theircourse work, lab work and career planning.

The objective of such exposure throughout the curriculum is to catchthe interest of students at an early stage, and thus encourage them to pursue those career paths. The project uses web-based modules to address its goals at two levels. One is to increaseinterest in science and engineering at the lower level courses for majors and non-majors. Theother is to improve retention by offering support for upper level courses. While some modulesare course specific, others are deliberately planned to be independent, allowing for maximumflexibility. All modules are available over the Internet.

As it stood, the problem statement was pretty muchopen-ended and was thus expected to generate different apparatus designs. There was, however,one important constraint on the design. It had to be explained with equations and principleslearned during class and during class only. In other words, if some students came up with amechanism that worked but they did not understand how its mechanics worked, this would nottranslate into a good project grade for them. This was clearly stated to them before they startedwork on their projects.Before putting together their projects, student groups met with the instructors to discuss theirproject plans. They

Under such a plan the studentwould have degree in mathematics from TWU and a degree in engineering from theselected university.

as an effective self-directed tool for open learning via the web. IntroductionIn the design of reinforced concrete structure, formwork design plays a crucial role. It is veryimportant for a designer to consider economy while planning the formwork for the reinforcedconcrete structure. Efficient and economical use of the material of which the forms are built is anintegral part of the design process. The forms for a concrete structure may cost more than theconcrete or the reinforcing steel; and, in some instances, they may cost more than the concreteand the reinforcing steel together (Peurifoy, 1976). The cost of formwork is significant, generallyamounting to anywhere from 40% to 60% of the cost of a

Several generalized plasticity models have been developed for metalsand soils to account for plastic deformations and to capture hysteretic effects. We wouldlike to mention here works by Mroz [5-7] where he and his colleagues described behaviorof metals under cyclic loads.In the present work we plan to apply a similar approach to analyze load history effectsand memory rules for the contact of two bodies with axisymmetric profiles Ar α based onthe solution by Jäger [8-10].

Accurate predictors of student performance early in the semestermay be used to induce positive reinforcement on the student. The main question guiding thisstudy is the following: can student final performance be accurately predicted based on tests ofprevious chunks of material?
