DistributedProcessing is a graduate-level course. It studies theoretical foundation and provides hands-onexperience in the area of distributed and parallel computing. In addition to the theoretical studies,the students are offered a sequence of laboratory projects with the state-of-the-art technologies.These new laboratory-oriented courses have attracted many students and received goodfeedback. The projects in these courses are shown to be effective in helping students understandthe concepts and theories of those subjects.1.

measurements, signalconditioning, and signal processing. The measured mechanical properties through lab exercisesinclude temperature, pressure, strain, and frequency of dynamic systems.Since the outputs of the sensors/transducers used for the lab exercises are voltages, a digitalmultimeter or an oscilloscope is utilized as a readout device. Then, students convert the basic labexercises to computer-based data acquisition systems using their own LabVIEW programs tomeasure and calibrate the sensor/transducer outputs. LabVIEW is short for LABoratory VirtualInstrument Engineering Workbench. LabVIEW programs are called virtual instruments (VIs)and a VI has three main parts: (1) the front panel for the interactive user interface, (2) the blockdiagram as

alongwith end caps and 4 inch plastic hemispheres. The pipe pieces range in random lengths formabout 40 centimeters to 1 meter. Weights of the different parts are determined, the caps are gluedonto the pipes, and the hemispheres are taped onto the caps. The purpose of the hemispheres is tostreamline the flow of water around the blunt PVC end caps. Students then calculate the amountof iron necessary to create neutral buoyancy of their subs. The weights of iron are toe-wrappedbelow the center of buoyancy of each sub to provide balanced weights and stability.A trip to the LSU in Shreveport swimming pool follows where each sub is placed in the pool at adepth that is one half the total depth of the pool. The subs are released and the time is measuredfor

We accomplish this goal bydesigning activities to help them develop an understanding of how people learn.We use this approach for specific reasons. First, this method is an effective one for accomplishing ourpurpose: that of linking student learning to faculty development. Second, it sends a message to professorsthat we believe they need to hear: their efforts to improve student learning are valued.In the remainder of this paper we describe: 1) the approach we use (background, mission,implementation) and 2) specific examples of how faculty have used their experience in our program topromote improved student learning opportunities in the College of

IntroductionElectromechanical watt-hour meters have been under continuous development since 1888, whenOliver Shallenberger and Thomas Duncan built a working model1. As a result of thisdevelopment, modern meters, such as the three-wire single-phase model shown in Figure 1, aremasterpieces of engineering design. These meters:• Operate with a registration error of less than 0.5 % over a load range of 0.5 to 100 percent of maximum load.• Maintain high reliability while withstanding direct

Finally, they perform another set of computersimulations to verify the effectiveness of the new tools they have learned.II. Course StructureThis three-credit course is composed of the seven modules shown in Table 1. The first fourmodules are considered to be Part 1: Kinematics. The remaining modules (Modules 5 - 7) areconsidered to be Part 2: Dynamics. As kinematics is the basis for dynamics, it is essential for acandidate to have a full understanding of Part 1 contents before proceeding into Part 2.Table 1: Modular structure of the kinematics course Module Title of Module Major Topics

Limited data from class 1 (Spring 1998)were used to develop a more comprehensive anonymous survey for class 2 (Spring 1999).The approach taken in this class is depicted in Figure 1. Full-time lecturing has been replaced byassigned pre-lecture reading and augmentation of notes through the Aerospace Digital Library(ADL).6 Instead, lectures are based on questions from the pre-assigned reading or explanationsof traditionally difficult material.

The majority of the workshop was taught or presented by USMA faculty, andits content was primarily based on the USMA educational training program for new civilengineering faculty. These facts, combined with the author’s experiences at other teachingworkshops and during his first year of university teaching, produced some (admittedly cynical)preconceived expectations of the ETW. The author’s main concerns with respect to the ETWincluded: 1) whether the “ExCEEd model” for teaching (used effectively by the military at anundergraduate academy) could be transferred to the world of “civilian” students

Remaining to be explored is the nature and value of the constant.

The tedium of iterative calculations is placed on the algorithms, allowing thestudents to concentrate on the parameters appropriate to their specific design application.I. IntroductionThe design of a mechanical component typically involves an iterative approach to determine anappropriate set of parameters that satisfy the requirements and constraints associated with thespecific design problem. For example, in the design of an extension or compression spring for aparticular application, the engineer must select the following parameters: 1. Type of spring to be designed 2. The material to be used to fabricate the spring 3. One
