Preparing students to actively participate in the learning process, be moreresponsible for their own learning and to become lifelong learners [9] were the main goals of theproject. Since students who are capable of self-learning are better prepared to become lifelonglearners, the teams were provided limited supervision and guidelines. To guarantee success, theirwork was assessed three times during the semester

Development of a Renewable Energy Course in Electronic Engineering Technology (EET) ProgramIntroductionEnergy plays an indispensable role in modern society. We all depend on a constant and reliablesupply of energy - for our homes, businesses and for transport. But have you ever thought aboutthe source of the energy you use? The majority of the US's electricity comes from burning fossilfuels (e.g. coal, oil and gas). With limited resource of fossil fuel on earth and thus prospect ofdepletion, the world has to turn to other alternative sources to provide our energy needs in asustainable way. It is also of a great concern that fossil fuels are a major contributor to climatechange. [1]In tackling these issues, President Obama came

It is easy to misinterpret cataloginformation on fans since they often rate fans by their maximum flow rate and/or maximumpressure output. These specifications do not actually have much value for selecting a fan for a Page 15.37.2particular application. In fact, neither of these values will ever be realized in a real application Figure 1 – Operating Point of a Fan Figure 2 – Operating Point of a Motorbecause the maximum flow rate requires zero back pressure and the maximum pressurerequires zero flow.
