The analysis is done with PowerWorld and is supplemented with MatLab calculations.The students were provided information concerning a small (seven bus, two generator) powersystem. They were required to assemble all of the information into tables, both in actual valuesas well as in per unit on a common base, before beginning the analysis. Since the system wassmall, students could manually calculate Ybus and Zbus values and compare them to thePowerWorld results. Any discrepancies had to be resolved in order to get the

problem. Ingeneral, there is at least the potential that these fluids could contaminate the pumpedwater or otherwise enter the environment. Furthermore, they can be expensive, and arerarely available where ‘appropriate technology’ is needed.Two separate student-designed pumps are presented that seek to overcome theselimitations. They were developed as part of 2-semester ‘Capstone’ design project classes.In one, air separates a small charge of working fluid from well water, reducing thepotential for contamination. The other pump is designed to boil water at lowertemperatures than might otherwise be necessary, by use of an inverted water column, andis useful when water need only be lifted a few meters. An alternative to this design is alsosuggested

Senior students involved inthis project have shown excellent progress by developing their technical and teamwork/socialskills as part of the Senior Design I and II core courses and have been successfully completingtheir course requirements.I. Introduction and Problem DefinitionWorldwide, the need for electrical power has increased exponentially. Energy needs versusclimate change relation has been a subject of a significant debate in the world. Recent scientificevidence indicates that global warming is underway 1. Observed changes show that despite largevariations from year to year, the global mean temperature has risen significantly in the lastcentury 1. Expected future increases in global average temperatures may have adverse

-cost Solar Tracking Photo-Voltaic (PV) Module and Wind Turbine Combination SystemI. IntroductionThis paper describes the design of a low cost, 0.9kW solar tracking photo-voltaic (PV) arraysystem as part of an undergraduate senior project. The solar tracking system is interfaced with a1kW wind turbine, a deep cycle battery storage system, a charge controller and an inverter. Solartracking is realized through “field” programmable complex digital circuit and alternatively with alow cost solar radiation sensing transducer consisting of green light emitting diodes (LED).Actuation of the panel tilt for azimuth tracking and rotation of the panel for solar tracking areoperated with a gear motor-based control system for adjusting the PV mount

It is a design intensive course that significantly utilizes projects to facilitate thestudents’ learning. It has become a very successful course with one of the largest enrollments foran elective course in the mechanical engineering program. The authors decided to use thislearning model for a new course in alternative energy systems with an emphasis on design.A new course with a design emphasis was welcome, as the mechanical engineering

Ten students were involved inthis project. Their mathematics background varied with three students just being transferred fromcommunity college and taking technical calculus concurrently with Power Systems 1 course.Several students did not take programming course yet.

Distributed generation is considered to be thenew and more suitable approach to providing solutions for socio-economic energy problemsthat have taken on considerable importance as we move into the new millennium. Theenhanced efficiency, environmental friendliness, flexibility and scalability of the emergingtechnologies involved in distributed generation have put these systems at the forefront toprovide power generation for the future8-10. Overall, the potential efficiency of anyconfigurations of hybrid power systems has been estimated to be about 80% by a generalizedmodel13.1.2 Course DescriptionThe courses consist of lectures, fundamental design exercises, a mid-term exam in the eighthweek, and a design project due during the final exam week (the

there.The course instructor felt that the project, supported by lectures in two-dimensional heat transfer,enabled the students to better visualize the two-dimensional temperature distribution. Thisopinion was supported by classroom discussions and project grades. The students had clearlydeveloped a deeper understanding of temperature gradients and the resulting conductive heattransfer in a two-dimensional solid. In order to determine how the students viewed the value ofthis project they were surveyed. Thirty one of the 32 students taking the class completed thesurvey. The survey, with the tabulated results, is as follows:Question 1.The problem enhanced my understanding of steady conduction heat transfer (heat flux) in a two-dimensional

medicine and you rarely hear: “I liked biology.” rather, the more common response is: “I wanted to help people.” Contrast this with an engineer's most common response: “I liked math and science” and it is easy to see why many young people don't see a future in a profession perceived as isolating and lacking in social relevance. Indeed, in engineering disciplines where social relevance is manifest, such as environmental or biomedical, women are well-represented.Mikic and Grasso30 also note: “the view of engineering as a profession in service to humanity isbecoming more widespread and thus is the inclusion of socially relevant design projectsthroughout the curriculum.” In their project where students design toys to teach children
