pollution rests on four basic assumptions [2]:1. Air is in the public domain. Such an assumption is necessary if air pollution is to be treated as a public problem, of concern not only to those who discharge the pollution but also those who may suffer as a result.2. Air pollution is an inevitable concomitant of modern life. There is a conflict between man’s economic and biologic concerns; in the past, this conflict was recognized only after air pollution disasters. We need a systematic development of policies and programs to conserve the atmosphere for its most essential biological function.1. Scientific knowledge can be applied to the shaping of public policy. Information about the sources and effects of air pollution is far from

IntroductionThe school of engineering at Grand Valley State University (GVSU) had it’s first graduates in1988. Since then, the school has continued to grow and now has students in electrical, computer,mechanical and manufacturing engineering. The faculty and curriculum are not departmentalizedby program as is found in most programs. As a result, it is quite easy to offer courses and projectsthat have multidisciplinary content.The engineering program at GVSU is practical in nature. This includes mandatory co-op employ-ment and a two semester capstone project. The

e-mail:rizkalla@engr.iupui.eduAbstractIn 1995, we received a NSF ILI grant to develop a one-credit laboratory component for our three-credit lecture course on electronic manufacturing aspects of printed circuit boards [1-3]. In thispaper, we describe how we have been able to increase the utilization of the equipment from itsoriginal intended use. We do this by developing two additional one-credit laboratory courses fortwo lecture courses using the laboratory that was set up with the grant. The two new laboratorycomponents will give students experience in the electronic manufacturing aspects of applicationspecific integrated circuit (ASIC) design for digital signal processing (DSP) and computerengineering applications.

In order accomplish our learningobjectives, we chose a combination of tools to help us describe these phenomena.As a comparative example of the strength of animation, we show the sinusoid and phasorrelationship. Starting with a MATLAB program, we provide a static description of a sinusoid asa complex vector in the phase domain. We describe the sinusoid generally as v(t) = A sin(2πft+φ)and its corresponding vector as A∠φ. Setting 2πft equal to θ , we display these graphically infigure 1.

Atypical laboratory apparatus is shown in Figure 1 Figure 1 A typical consolidation apparatusThe apparatus consists of a loading frame and a cell. The cell comprised a ring to confine the soilsample, a reservoir to prevent drying out of the sample, porous stones for drainage of the porewater, a ring cap to hold the ring in position, and a loading cap to transmit load from the loadingframe to the soil.

It was decided to dedicate a complete wall within aclassroom for this purpose. As the map developed, an additional wall was added to contain mapsfor each of the four upper-division discipline-specific elective paths in our curriculum.The overall arrangement of the map is shown in Figure 1.

To address this concern a Nusselt number classificationsystem has been developed.There are examples of heat transfer classification systems that have appeared in the literature.One of the first of these is a convection coefficient classification by Lauer [1]. In this system,convection coefficients are classified and cataloged according to twenty two different geometries(e.g., Single Flat Vertical Surface-Vertical, Inside of Tubular Surface-Horizontal Tube, andGranular Solids), followed by six different thermal conditions (e.g., Cool Wall-Warm Gas, CoolWall-Condensing Vapors, and Warm Wall-Cool Liquid), and finally by flow

Programs ofintervention aimed at identifying and treating these potential dropouts have grown dramatically.II.

Students may lack the basic academic skills necessary to be successful in a college program. 2. Students may have received poor advising during their initial semester and

The reaction force could be simply measured with a load cell. We also could estimate thereaction force experimentally by measuring the static-pressure distribution on the wall. Allforces, theoretical and experimental, should be the same. The static pressure P1 on the wall in thearea of the jet impingement would be higher than outside this area, say P2 on the opposite side ofthe wall. What would be the pressure P3? According to Bernoulli’s equation we would expectthis pressure to be lower than P2. The question arises how pressure P3 contributes
