That will be in the z direction here and representthe thickness of the aquifer. It must also be recognized that this aquifer has no boundaries in thehorizontal plane. Therefore, the flow rate computed from this flow net needs to be adjusted torepresent flow for a unit length in a direction perpendicular to flow direction. The followingexample will help clarify these points.V. EXAMPLE RESULTS From Figure 3, a convenient portion of the flow net is selected. This section is marked inthick lines.

The radar pulseis directed into the concrete member, and patterns created by the reflected waves are observed. Thespeed of pulse in concrete is about 38 to 64 x10 -9 mm/s, as compared to approximately 305 x10-9mm/s in air. Penetration depth ranges from 0.5 to 30 m depending on antenna frequency andbandwidth. Usually, frequencies of 0.1 to 1 GHz are selected depending on the penetration depth andresolution desired. The most difficult aspect of the inspection with radar imaging techniques is theinterpretation of radar signals. The signature of concrete delamination often assumes the shape ofa depression on

these observations, a quarter-long team project was introduced, where groups ofapproximately 10 students manufacture a working Stirling engine, as shown in Fig. 1.Hands-on labs where students produce working mechanical devices are far from new. Since the late1950’s however, many of these labs have been replaced with analytical work and exercises inengineering science [1,2]. Dejong [1] reminds us that it was the Grinter Report [3] that sent engineeringeducation in a much more theoretical and science based direction. Although these changes inengineering curricula led to many improvements, practice-based courses in the areas of design andmanufacturing have suffered.In the past several years, many authors have reported their efforts to

the more complex functions (voltage-controlled oscillators andfilters) necessary for a fully functional system are usually provided for the project due tothe complexity of these circuits for students at this level.INTRODUCTIONWhen I was assigned to teach the introductory circuit analysis course (ECE 202), I wasinformed that I would have to provide an “honors component” for those students taking itas an honors course, ECE H202. (There is insufficient demand to offer a stand-alonehonors course, so ECE H202 is taught as an “add-on” course, with the honors studentsattending a standard section.) I decided to adapt the work I was involved with during thelate 1970’s in electronic music synthesis as a project for ECE H202.HISTORYIn the mid-1960’s
