12.642.9principles etc., (b) videos on different major engineering projects of modern times, (c) field tripsto engineering industries, (d) application oriented problem solving on basic and intermediatemathematics as well as Statics, Electrical Circuits etc. and (e) laboratory experiments.During the fall 2006 semester, for the first time, students were asked to fill out a surveyquestionnaire in order to get a feedback about this new format of the course. The class consistedof only 10 students. There were 12 questions in all, 6 were about the course itself and 6 were onthe lab experiments. Results from these questions were shown in the following table. Table 1. Responses from the survey questions from fall 2006 semester Q 1) Which was most enjoyable

N and P channel depletion and enhancement MOSFETTo provide the students with an enhanced hands-on experience of the electronic componentsstudied in their lectures, a set of 12 learning oriented, pre-defined labs are incorporated in a twohour lab course. These labs cover the following topics

Silicone oil Laser Internal cylindrical enclosure (water) Figure 3. PIV experimental set-up for vertical jet flow characterization. PIV images and its corresponding 2D velocity field are shown in figure 4, as afunction of enclosure disk height, H. As can be seen in figure 4(c), the fluid exits thepipe and initially forms a jet-type structure as it enters the enclosure. The flow rate insidethe pipe is measured using a flowmeter, Q = 2 l/min, which corresponds to a mean jet Page

components of the laboratory apparatus. A blower draws air through a ductconstructed from acrylic tubing of two diameters. The inlet end of the duct is open to thelaboratory, and has diameter d1 and length L1. A longer section of tubing with diameter d2 > d1connects the inlet section to the blower. The transition from d1 to d2 is abrupt. Page 12.1562.8 Inclined manometer Velocity Blast ∆p probe gate Q
