Details of classes, methods and functions will be presented in the full paper. Thepaper presents examples of Buck, Boost, BuckBoost, and other converter topologies. This methodology is generalenough to generate waveforms in several DC-DC converters and inverters.1. INTRODUCTIONThe steady state operation of power converter is fairly complex and require clear understanding of circuitconfiguration which may not necessarily be constant over a period of time. Analysis and Spice simulation are twowell-known methods of obtaining the time-domain waveforms of voltages and currents in different parts of

Capstone projects are oftenmultidisciplinary 4, further replicating the types of projects students will experience in industry.Capstone projects can be defined as project-based learning. Project-based learning brings skillsand knowledge together to solve an ill-defined or poorly formed project 5. This is epitome of thecapstone experience. Students generally have their capstone

right in Figure 1-1, the only graded items for the course werefourteen labs constituting 40% of the overall grade and two exams weighted at 30% each.Of the students spoken to, most felt that the graded content and associated weights shouldbe revised because the labs that constitute only 40% of the grade required too much time.Additional comments were that although exams were graded in a generous way, the examquestions were quite a bit more in depth even though time was spent in class going overpotential test questions in the days preceding an exam. Students felt they often did notknow what information the instructor was seeking on the test questions. One studentsuggested graded homework assignments might help students understand the

Most people would agree that technological change has had a significant influenceon the way we teach and learn in past couple decades. Distance Education, Distance Learning orHybrid Learning has become a more demanding practice in academia as indicated in research.Accordingly, 29.7% of all graduate and undergraduate students have taken at least one distanceeducation course.

The inventory planning subsystem is concerned with buildingorders for the suppliers and dispatching materials to the customer wherein material handling ismore involved with transferring the goods inside the warehouse. There are different functionslike labeling, breaking bulk, light assembly, order entry and fulfillment, packaging, pick andpack, and transportation arrangement necessary to carry out material handling activities 2. Allthese operations are cost intensive; the most expensive is the pick and pack process whichgenerally constitutes about 50%-75% of the total warehousing
