Display BoardFigure 1 shows the General Interface and Display Board (GIDB). This board attaches directly tothe pin connections on the TLCS-900H EVB via connectors on its underside, and thus interfacesto all of its functionality. An external power source is utilized for this board to provide adequatecurrent to drive all circuits and components. An LM7805 voltage regulator provides 5-voltpower as defaults for all drivers. The central feature of the GIDB is that it has two 16-pinsockets that are used to connect the Signal Conditioning Board and the High-Current DriverBoard. Circuits from these connectors pass through the GIDB to the pin connectors on theTLCS-900H EVB, thus completing the interface to the entire system

parameters in Callender-Van Dusen equation. Since the uncertainty of temperature and resistance measurementsduring calibration determines the accuracy of the temperature measurements usingplatinum detector, it is necessary to assess the calibration errors. A simulation package isdeveloped that applies different levels of errors into measurements used for parameterestimation. The goal is to study the influence of calibration uncertainty on thetemperature detector’s readings. The next challenge is a practical realization of thecalibration process. A simple experiment is proposed and the least square fit is used toestimate the parameters.1. IntroductionElectrical resistivity of metals and semiconductors increases when they are heated.

The initial survey revealed that students had a relatively high interest in taking thecourse despite thinking that it would be more difficult and have a heavier workload than theaverage UM engineering course. After completion of the project, students found the designmodules to be productive and generally enjoyed doing them. The highest average rating(4.0/5.0) was attributed to enjoying working in a group. Overall, the modular design project wasan effective way to promote the design process, elucidate relationships between fundamentalprocesses and practical applications, balance students’ workload throughout the semester andfoster a cooperative learning environment.1 Introduction“Dynamics of Environmental Systems” is a senior

Students are required to use themanufacturer’s data sheet to analyze the requirements to set the frequency, amplitude andwaveform shape of the output. Using the generator to drive a speaker provides the opportunityto examine the effect of the 600Ω output impedance on a 4Ω or 8Ω speaker.

The program’s structureThe four-year program totals one hundred and twenty course credits. As shown in Figure 1, theprogram consists of five units: mathematics (13 credits), computer science (8 credits),engineering science (67 credits), complementary studies (15 credits), and design workshops (17credits). The engineering science unit includes 57 mandatory and 10 elective credits. Thesecourses cover the traditional disciplines of mechanics and electricity. Since the program offersthe fundamentals of mechanical and electrical engineering, elective courses are limited to 10credits. Thus, by a suitable choice of five optional
