Xcan be found by matrix inversion (X = A–1B). Eq. (7) is solved once to compute a dc bias-pointsolution. In dc sweep analysis, the value of one independent source in B is stepped through auser-defined range and the solution is computed at each step.Figure 11 defines currents and voltages in branches containing capacitance or inductance.

rudimentary understandingof discrete signals. Since these are computer simulations, one would need to remember thatsimulations of analog processes are valid when the results of the processes all fall within theNyquist rate determined by the original chosen sampling frequency. The discussiondevelopment in section III gave an example of a process that would result in frequencies beyondthe Nyquist rate. The concept of sampling frequency gets interesting and potentially confusingwhen we simulate the sampling of analog signals where we can talk about two samplingfrequencies: the sampling frequency of the entire simulation and the sampling frequency atwhich we retain samples from the simulated signal. I refer to the former as ‘simulation clockfrequency

The author wrote elementary tutorials forthe first two lab/project periods to help students gain basic proficiency in using DYMOLA. Theobjective of Lab 1 is to use DYMOLA to create a model, solve the ODE, and plot the results. Theobjective of Lab 2 is to use MATLAB to import and plot results from DYMOLA simulations. Both

IntroductionCurrently colleges and universities are faced with an ever-increasing demand to optimize theircurriculum and increase the content of their courses due to the rapid change of technology and itsattendant introduction of new material into the curriculum1. It has become obvious within highereducational institutions that the sole reliance of faculty on traditional “chalk and talk”approaches is just not as effective as other more interactive methods 2. Hence engineeringeducators are now making use of an increasing number of computer simulation packages to aidthem in attaining their

A few weeks later they were asked to respond to a web-based surveyvery similar to the one described for the EMgt-475 class. Thirty four out of the 35 studentsenrolled answered the questionnaire. They were asked to determine and record their Myers-Briggs personality type, whether they were undergraduate or graduate students, their homedepartment, work experience, current GPA and grade expectations.

By witnessing physiologic variability in the laboratory, they come to understand that physiology simulators can never fully replace live animal experimentation. • Euthanasia: In general, while students do not regard the laboratory rats as pets, they do express significant concern, and some sadness, when their first animal is euthanized in Lab #2. Before injecting a euthanizing agent for the first time, I work intensely with each individual laboratory group to address the need for euthanasia and how the agent will work.

With the advent of high-speedInternet communications an alternative approach to providing hands-on experiences hasbecome possible – remote operation of real equipment. Such remote operationexperiences are fully learn-by-doing with nearly all the positive and negative aspects oftrue hands-on laboratory work.This past year the process control class at Washington State University was taught usingboth of these approaches.

Since some students are clearly giftedin visual arts, I have allowed students to choose an animation as one of their peer-reviewedassignments. The best of their animations can then be incorporated into future lectures.Peer review can be used for research papers. Though I have not yet assigned this in acomputer-architecture course, in my operating-systems course, I had each student select aresearch topic from a set that included topics like “Scheduling in Windows NT,” “Deadlockhandling in Unix or a particular flavor of Unix,” and “Virtual memory in

In symbolic simulation, the initial state of a processor is represented withvariables, while the next state is computed as a function of these variables, based on the descrip-tion of the processor. In the sequence of three projects, symbolic simulation is done according to the inductive cor-rectness criterion in Figure 4, which checks the safety property of a single-issue pipelined proces-sor—if the processors does something during one step of operation, then it does it correctly.Specifically, if the implementation makes one step starting from an arbitrary initial state QImpl

-agent robot group is shown to demonstrate extremely efficient navigationalpatterns based upon a control scheme that incorporates the concept of Occam’s Razor. Thefundamental idea upon which this approach is based is that a multi-robot team can cooperate todetermine the shortest path through an unknown environment given only a very simple set ofrules. In addition, the approach being presented in this paper can be successfully implementedusing very simple sensors. The idea was implemented with two robots. In simulation, groupsconsisting of over sixty agents were tested, and it was shown that a near optimal (shortest) pathemerges through the environment without mapping the environment.

The naming conventioncriterion was used because the lab is equipped with SLC 500 PLCs. We saw no reason toteach one naming/numbering convention for the simulation software and another for theactual SLC500 hardware. (2)The software should cost less than $50. This would allowthe students to purchase the software and run the simulation problems on their ownpersonal computers outside of the scheduled laboratory time.

This freshman course emphasizes the development of a 3-Dgeometric computer model and application of this digital database to all phases of the designprocess. The students make freehand sketches, build computer models, mate assemblies of parts,perform various analyses, create kinematics simulations, build rapid prototypes, and generatefinal design drawings. An assessment of student outcomes in the course was conducted in theFall 2002 semester using a series of self-reported learning surveys.
