Unfortunately, the trends aresimilar for engineering students and the numbers are even higher than the college-wideaverages. Between 1964 and 1992 the number of engineering students who self-reportedcheating in college increased from 58% to 74%.6,7 In terms of the extent to whichstudents admit to cheating, engineering students are second only to business students, asshown in Table 1.Table 1: 1992 Levels of Cheating Among Students of Various Disciplines in College6 Discipline Percent who self

The methodof introduction was to create an optional part of a sophomore-level course in which the studentswould have exposure to various aspects of mechatronics. Custom program elements weredesigned and fabricated including the VT Project Box (Fig. 1), the PIC Visual Development(PVD) Software (Fig. 2), and various sensors and actuators.

The theory and real-time principlesare presented in short lecture modules like the one shown below, while the laboratory exercises areperformed using a DSP development board attached to the student’s local computer. The use of aphysical development board allows more realistic laboratory exercises to be performed than woulda network-based simulation tool. Student interaction, instructor feedback, and course organizationare provided through the web interface. The student interaction and hands-on aspects of the coursemore closely approximate a university experience rather than a typical asynchronous web-basedtraining course.1.

In addition, there is aseparate window for high-resolution graphics and video, and another window for real-timeaccess to an interactive discussion forum. For the laboratory portion of the course, streamingvideo of actual demonstrations of laboratory procedures is used. In addition, for each type oftest, a “rock breaking simulator” has been developed that allows students to collect their ownunique data set, with subsequent data analysis and report writing.The online geomechanics course will debut in 2001 and will be part of the Arizona Tri-University Master of Engineering program (University of Arizona, Arizona State University,Northern Arizona University)1.

These measurement techniques will be implemented in theform of embedded systems.

Engineering Kinetics Class. In addition Iwill explain the key goals and how well they were met. I found that the key to the success of thiseffort was providing the students with a long list of possible example projects and their pointvalue. The resulting projects are sometimes just the necessary work to fulfill a requirement butmany times they show great creativity and insight.I. IntroductionI began using open beginning projects in our senior course in equilibrium and kinetics for severalreasons. My goals were: (1) to encourage students curiosity, (2) to recognize the diversity of ourstudents desires and interests, (3) to encourage, particularly our top students, to address morechallenging problems, (4) to allow these seniors to order their own work

This project was concerned with the manufacture of model concrete to construct 1:12 scale models.2. Project 2: behavior of steel connections for low-rise building frames under seismic loads. This project investigated the use of 1:2 scale models to investigate a novel technique to enhance the energy dissipating capability of semi-rigid connections used in low rise buildings.3. Project 3: testing and evaluation of modern aseismic systems utilizing small-scale models.

so. We have used Geometric Programming in this paper based on our experience of this technique in design and manufacturing problems. Other attribute of this technique is its ability to predict the proportions of various cost terms even before the design is attempted. However, we want to test the applicability of other similar nonlinear programming techniques to the optimal design problems based on life cycle costs and compare accuracy and other pertinent evaluation parameters later. LCC is divided in to two main categories, 1) acquisition cost and 2) support cost. The acquisition costs are the costs associated with the design and build of the product.

IntroductionIn microwave and optical waveguides, phase velocities are infinite at the cutoff frequency andare always greater than the velocity of light in the dielectric in the guide, where group velocity iszero at cutoff and is always less than the velocity of light in the dielectric in the guide. As thefrequency increases far beyond cutoff, phase and group velocities both approach the velocity oflight in the dielectric in metallic and dielectric guides. These phase velocities are described asfast waves. In traveling wave tubes, slow wave structures create phase velocities with velocitiesalong the axis of the structure much less than the velocity of light. In slow wave structures suchas

(2) If so, could this enhanced motivation be linked to increased studentunderstanding in physics?

The device uses the Serial Peripheral Interface (SPI) tointerrogate one or more controllers and cycle the contents of the LCD display. The display unitis configured as an SPI master (one who can initiate the transfer of information).Multiple slave devices can be connected to a single SPI. Thus, one can easily have one deviceper display, one display for many devices, or a mixture of the two.

In 1998-1999 there was a major increase in students interested in participating in the MIEprogram. One of the reasons has been the student awareness that the REU coordinatorprovides for the students. Visiting student’s classrooms and disseminating informationhas been a very successful mechanism. In summer and fall semesters, the number ofstudents applying ranged from forty-two to eighty students.
