During normal operation these devices can implement thedesired functionality of the system while during testing they can be configured to supportspecific test requirements. These devices can be used as test generator for other neighboringcomponent(s) or response collector from them. These responses can be analyzed to identifyfaults in the system. As such, the dual use of reconfigurable devices can be an interestingacademic material at

On the computer, students work with simulations of simple mechanisms and get todetermine their degrees of freedom by applying Gruebler’s equation. This is then related to actualmechanisms that the students have encountered in their video tour of the CAT facility. This isimportant in helping the students make the connection between the theoretical concepts beingdiscussed and their practical applications. Specific mechanisms of particular practical interest arethen discussed and Grashof s criteria for classifying mechanisms are introduced. Figure 2

The A/D converter digitizes the analog input data. Theonboard FIFO (First In First Out) memory provides a temporary storage of data inbuffered data acquisition applications. There are also two D/A converters that convertdigital data to analog form and pass it to the analog output ports for use by externaldevices.The DAQ board used in this application is MIO-16E-10. This is a multipurpose I/O dataacquisition board with 16 analog input ports and two analog output ports. Its settlingtime of 10 µ s determines its maximum sampling rate of 100 kHz.

If these questions are carefully considered and the requirement clearlyarticulated, then the outcome will be portfolios which work for their intended purposes.Rationale and ResultsI began using portfolios 4 years ago after attending a workshop on authentic assessment whichdescribed how portfolio assessment could be implemented in a math/science curriculum. Mymain purpose was to provide a structure for reflection. I had the disturbing feeling that somestudents truly did not understand why they received a poor grade at the end of a semester.

People also are growing older in record numbers and thoseaging into disability represent an ever-increasing proportion of the population.

The course, taught by NU faculty and a few outside specialists, rapidly grew in sizeand expanded to various locations.In the late 80’s, the first Professional Engineering course, Mechanical Engineering, was offered.The course was organized to run for 12 weeks for 2 ½ hours each session. The course topicsmatched those covered in the exam specification. The first session covered overview andstrategy. Subsequent sessions addressed the subject areas. Each session covers major theories, asubject review, and sample problems to

A shockwavemoving upward at speeds of approximately 1.1x108 m/s forms at the leading edge(furthest from earth) of the downward moving charge and it is this shockwavewhich we perceive as lightning. Although there are return strokes starting fromthe cloud and traveling downward, most return strokes travel upward. The highspeed of the shockwave and amount of visible light given off and the persistenceof human vision make it nearly impossible to determine which direction theshockwave is moving without using cameras or other equipment3.Lightning is

As electrical engineering expanded, the need forall students to study all subjects within electrical engineering was debated. A feeling developedthat a large portion of the students would never need or use some of the more traditional material.It ceased to be relevant to the students' careers. Pressure was applied to cut some of these moremature topics. Energy conversion lost out.Since the late 1970's we have experienced rapid changes within the energy conversion field withthe advent of power electronics and wide spread use of permanent magnets.

The sixaccelerometers are used to sense rotation as well as translation in each of the three spatialaxes. The accelerometer provides a digital waveform of variable pulse density suitablefor input to a pulse counter. The signal generated by each accelerometer is fed into acounter that is multiplexed onto a single bus via tri-state outputs.

still very high5. The mostcommon metrics used for student retention are the freshman retention rate and graduation ratesfor a freshman class after five years. The graduation rate for underrepresented minority students,namely African Americans, Hispanics and Native Americans, is much lower than that of non-minorities. The average graduate rate of underrepresented minority students for the freshmanclasses that entered a sample of 112 institutions between 1986 and 1989 was 35.0 percent (alldisciplines). ASU was not included in this sample because graduation rates are very sensitive toan influx of transfer students and ASU has a high percentage of transfer students. This rate hasremained the same as for students graduating in the 1980’s. However
