thecreation/adaptation of such measurement methods as needed in a research or an industrialenvironment.Numerous optical techniques are available for both quantitative and qualitative measurements.Many use sophisticated and expensive setups that include imaging components. A set of precisetechniques are based on a combination of inexpensive diode lasers, mirrors, and prisms. It is onadapting these techniques to laboratory experiments that this team will focus on.The following figures display the components of a preliminary design for creation and testing ofan apparatus for measurement of the angle of twist of bars by application of torque. A mirrorattached to the free end of the bar reflects the laser beam back on a scale before and after

their design. Thefinal section was a reflective analysis in which each team discussed the process of designing andtesting their improvements; specifically what worked well and what did not. This section alsoincluded proposed future improvements for their design. Ideally, the students would recognizethat many of the irreversibilites in their design presented an opportunity for potentialimprovement. Finally, this included a comparison with other sources of conversion technologiesin terms of capital costs, fuel costs, and efficiency while including proper citations. Acomparison with current technologies demonstrated that the efficiency of the student designswere roughly 1000-10,000 times less than modern engines and power plants, thus adding

There was a good deal of variation across institutions in students’ responses to theselearning outcomes. These may reflect the variation in course composition of the students, Page 22.883.10characteristics of the instructors, variation in implementation of the shake tables, developmentsover time in the technology, etc. While a larger sample and a more thorough data collectioneffort necessary to estimate associations between all possible variables were beyond the scope ofthis study, we are able to partition the variance into within

Theysoldered resistors on their Mudduino board to interface with an IR reflectance sensor and aphototransistor. They attached a connector to their battery pack, stacked the battery and boardon the chassis, and bolted the whole robot together, as shown in Figure 4. In Lab 6, studentslearned to control the robot in C. They developed their own library of motor control functions.They learned to read the sensors, and programmed the robot to drive toward a light, stopping if itwere about to dive off the lab bench. They attempted to drive in

The first one wasthat the corresponding measured object had to be flat and with a relatively rough surface. If theobject subject to measurement had a smooth surface, it would be harder for the mouse to Page 22.766.11function normally knowing that the reflection of the emitted light from the mouse will beinfluenced and will affect its tracking performance.Another issue that threatened this VI’s performance was the maximum length it could measure.It is known that the mouse can move a maximum distance equal to

that contains a thermistor, a few resistors, andan operational amplifier. In general, the bridge circuit is used to detect small changes in theresistance of any of the resistors, which is reflected as a change in the output voltage. Thestudents are asked to derive the expression of the output voltage, Vo, as a function of the inputvoltage and the Wheatstone bridge resistive network, which contains the thermistor. The studentsare encouraged to refine their expression into the fewest terms possible to make MATLABprogramming and downstream design much easier to handle. The students are then required towrite a MATLAB script to simulate the thermistor and the Wheatstone bridge circuit. They are touse the thermistor formula (Equation 1) and the Vo(T

Page 22.1072.9The first statement was intended to test whether the students felt that the MEA was a less valu-able assignment than a more traditional assignment without the simulated client. 52% of therespondents disagreed or strongly disagreed with the first statement and 20% agreed; because thestatement is written so as to reflect negatively on the MEA, this response suggests a preferenceby the students for the MEA rather than a more traditional cookbook approach. 65% of therespondents agreed or strongly agreed with the second statement, while 23% disagreed, nonestrongly. Taken together, the results of the two survey questions indicate that most studentsrecognized the need for the use of good communication skills in the MEA assignment
