Although no attempt is made to cover a plethoraof environmental legislation to define “acceptable” emissions, the important aspect taught to thestudents is that whether zero material waste and zero energy processes could be developed whichare inherently safe and environmentally benign.Course presentationBoth undergraduate and graduate students in chemical engineering and chemistry take the courseas an elective in their programs. The course presentation consists of three lectures per week.

prototype of the future TexasInstruments TLV5651, 10-bit, 125 MHz communications DAC. This high-speed DAC will beused in cellular telephone base stations to assist in reducing saturation of base station circuitsduring peak periods. The THS5651IDW DAC has a diagonal pattern for its segmented currentarray. The author made a study of this pattern to determine if there were major problem areasassociated with using a diagonal pattern to overcome output differences in adjacent current cells.Texas Instruments provided 36 THS5651IDW DACs and the use of their laboratory facility.LabView® software was used for instrument control and data acquisition. MATLAB softwarewas used for calculations and plotting data. Calculations were made for all 36 DACs

It was obvious that a detailed discussion of all 12 courses was not possible eachyear. Thus only selected courses are reviewed each year, although all courses arereviewed on a set cycle. Because of their importance in the curriculum both semesters ofthe unit operations laboratory and both semesters of the design class are reviewed eachyear.

We have developed a graduate course on microstructural characterization, analysis,and modeling that is based on concepts of stochastic microstructures and uses model systemsbased on spatial geometry concepts of point processes, packings, and tessellations. Using discreteconstituents such as discs, we develop the fundamental ideas of spatial geometry and imagealgebra more transparently to aid student comprehension. Once these principles are covered, weextend them to more complex structures such as multiphase materials.IntroductionThis paper discusses our experiences with a 3-semester-hour (2 lecture and 2 laboratory hours)course taught to graduate students in the Department of Mechanical Engineering at NC A

The students were required to deliver the following items:1. A Gantt chart detailing the time table of activities: This should be turned in within 5 days after it is assigned to the students. Subsequently the students are expected to submit a progress report based on the proposed time line.2.

The linear actuator control system will also be used in an electivecontrol class (ME 475) in the Fall 2002 semester. In this class, students will take a much morecomprehensive look at the controller. Both frequency domain and time domain (root locus)approaches will be used to design PID controllers. Comparing theoretical results to actualexperimental results should improve student understanding of controls.AcknowledgementsMuch of the equipment and facilities used to develop this linear actuator control system weremade available by the Electro-mechanical Systems Laboratory (EMSyL) at The University

on a weighted percentage of points scored in exams, homework,and other graded assignments2. However, if a course has ten learning objectives that receiveequal point weighting, a student can theoretically score 90% of points without demonstrating anycompetence in one of the learning objectives. Competency testing3 provides direct evidence ofthe accomplishment of learning objectives, but typically only on a pass/fail basis for eachlearning objective. Our goal was to develop a grading system that would allow us to assigngrades based on demonstrated mastery of learning objectives. Since the successful completionof many laboratory experiments and exam questions require the attainment of several learningobjectives, it is difficult to determine the

It is desirable for the students to learn these communication skills in thecontext of their specific disciplines; therefore, the trend has been towards integration of writingexercises through design and laboratory reports in the engineering courses in addition to theircourses in the humanities component. Although much emphasis has been placed on theintegration of both written reports and oral presentations into the core engineering curriculum,little has been said or done concerning the use of graphics as a communication medium.
