-existing simulation programs or, in the case of Operating Systems, to modify thekernel of an existing operating system. I have found that, given the lack of a strong ComputerScience background among our students, a better approach to this problem is to have the studentswrite simple simulations themselves. This technique provides a more intimate understanding ofthe processes they model while simultaneously giving the students valuable programmingpractice.In this paper, I will examine one such problem from my Operating Systems course – modelingprocess scheduling algorithms. Computers are time-sharing devices: only one process canactually be using the CPU at any given instant. The procedure for selecting which process to runand for how long can have

To this end the authors have developed aninteractive and user-friendly environment referred to as SCEFMAS (Simulation and ControlEnvironment of Flexible Manipulator Systems) 10. As an on-going development process, theSCEFMAS environment is enhanced by the addition of intelligent modelling, a new menu drivenuser interface with GUI based facility, and the

One of the methods ofreducing this short fall is to use simple animated virtual models, which demonstrate basicstructural design concepts that can be used to enhance the students understanding. Theinteractive computer aided learning (Haque 2001) allows students to proceed at their own pace,motivated by a curiosity about “what happens” interactivity and “the need to know” the design/analysis principles.McManus, and Segner (1991), are of the view that visualization will take many forms in theconstruction industry.

I decided thatinteractive software simulations of the chemical reactors my students studied could help themlearn by supplementing the static material in their textbook.The goal was a laboratory, in software, filled with chemical reactors which the students couldoperate. A variety of reactors with different features and complexities would be present toillustrate different concepts. Since there are several outstanding texts in the field of chemicalreaction engineering, the focus was to provide the experimental apparatus and data collectionmethods rather than complete pedagogical

moststudents who complete the course are not be able to create a reasonably designed new object-orient application. The reason is that design is a constructive task which requires someexperience, whereas assignments in a first course are oriented to coding very specific assignedtasks. Of course, by necessity, the first step of learning focuses on programming rather than ondesign.Should engineering students be advised to take a second computing course? I recommend thisfor the following reason: There is a “language” (in part a visual notation) and methodology forspecifying the requirements and design of software systems. If engineers need to create theirown programs they should know how to program; but, if engineers ever need to interact withsoftware

Inteaching the concept of the rotating magnetic field, computer assisted teaching and animationtools in both MatLab and MathCad are used. Through the computer simulation and animation,and analysis of MatLab or Mathcad code, the rotating magnetic field concepts can be proved,introduced, and demonstrated very easily and quickly.

The advantage here is that complex algorithmic programming can be donevisually on the internet using J-DSP and then executed in MATLAB. Conversely MATLABprograms can be mapped to flowchart-like diagrams and run in J-DSP. Although Simulink doesthe latter as well, the J-DSP tool runs on any platform requiring only a Java-enabled browser.Moreover the Java software integrates seamlessly with web content and animations supportinginternet courses. The MATLAB scripts are generated with a new interpreter that has beendeveloped for J-DSP. This interpreter encodes all simulation parameters in a script that containsthe equivalent

One way can show the actual motion of the spacecraft body; another way is that thesimulation can show spacecraft motion as seen through spacecraft telemetry (e.g., angular ratesas transmitted by on-board gyroscopes). The tool that I have used to do this is Matlab. I haveused a simulation that shows how the coordinate axes change as a result of applying a set ofEuler Angles. I use Matlab simulations of tri-inertial spacecraft behavior and have used this tocompare to the approximate behavior derived in class. I have used simulations to illustrate

After the game, the students work on the car steering subsystem, speed subsystem, systemintegration, and then enhancements. There are scheduled lab check off dates and procedures foreach subsystem. Diligent students have little trouble completing the tasks on time, but othersmay miss one or two deadlines. These students then have to use the open shop hours to catch up.They don’t suffer a grade penalty unless they fall so far behind that they miss due dates for labreports.The completed

often avoid creativesolutions that might prove embarrassing in a public load test. Designs rarely result from asystematic process. Students derive structural concepts from photos or from vague notions ofwhat bridges ought to look like. Designs, if they are developed at all, are seldom informed bymath or science. Even the design criterion—maximum strength-to-weight ratio—is unrealistic.Actual bridges are designed to carry code-specified loads safely, at minimum cost. Actualbridges are never designed to maximize strength-to-weight ratio.These inadequacies led us to use computer simulation in lieu of a physical model-buildingproject. This decision is consistent with the work of Harmon and Chung, who havedemonstrated that simulation can be used to
