developed in Working Model. When a complete mechanism made up of several links andjoints is considered, Gruebler’s equation for determining the degrees of freedom of a mechanismis introduced. 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

contains many components that are necessary for data acquisition. A typicalboard has 8 analog input data channels that are multiplexed and applied to theinstrumentation amplifier. 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.

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

The lab describedin this paper introduces a concept for studying the impact of dispersed resources in electricutilities. While some new experiments are outlined, there are several others that can be createdwith some thought. The setup cost of the lab is somewhat high given that PV and wind powersystem capital cost can be rather high. An alternative is to simulate the characteristics of theseresources by hardware.5.

To resist change in favor of therelative comfort of the status quo is certainly a strategy to be avoided. Those who profitfrom the various agents of change are those who can accurately predict the implicationsof technological, business, or social changes. Unfortunately, these implications are oftendifficult to foresee.
