, and by other authors1-4. For example, the supplemental material to the textbook byMunson, Young and Okiishi4 includes a video of water draining from three holes in a two litersoda bottle. Libii1, and Libii and Faseyitan2 describe a tank-draining experiment where the drain Page 15.161.2orifice is at the bottom of the tank. Saleta et al. use a configuration similar to that in Figure 1,below3. The experiment we have developed uses a digital camera to measure the jet trajectory(like Saleta et al.) and a pressure transducer to measure the fluid height (like Libii andFaseyitan). Our version of the tank draining exercise is unique in that the

One of the distinguishing elements of education is the labexperience [3]. There is a growing interest in using the Internet to provide students withremote access physical laboratory apparatus [1, 2, 5, 6]. However, the adoption of theInternet to deliver to deliver and implement laboratory experiences has been sloweddown by concerns about quality of instruction [3, 4]. Engineering educators face newchallenges to design effective learning experiences for the next generation of engineers,using the emerging technologies [2, 6]. The problem for the Circuits and Instrumentationcourse at Michigan Tech was that it had a significant

The introduction of SMT/PCB facilities has had a significant impact across theentire undergraduate curriculum, from sophomore year core courses through senior designprojects, and has improved the overall educational experience and outcomes.IntroductionRecent curriculum redesign in the Department of Electrical and Computer Engineering at DukeUniversity funded by the National Science Foundation has focused on real-world problems as ameans for the successful training of modern engineers. The redesigned curriculum provides ourstudents with more opportunities for hands-on experiences in applying theory to practicalapplications.1 Project-based learning is a central driver in this process which has been shownthrough prior work to motivate

forboosting the confidence and creativity of freshman students while introducing them to theengineering disciplines. The core philosophy behind the LWTL concept is to create a learningenvironment that empowers students with a “can do” attitude. One of the essential ingredients tothis environment is transitioning students from their previous learning mode to a more self-reliant mode of study. The LWTL curriculum encourages this transition through the use of acommercially available “lab” and real-world projects.The LWTL curriculum was motivated through a combination of the following factors: 1. Our college vision of “being the best college in the world at integrating engineering and science in research and education” 2. A noticeable change in

systemcontinually. Given a simulated industrial problem with a set of reference information,students design their systems to solve this problem. To reach this goal, we compared ourrequirements with Kolb's learning cycle1: concrete experience (experiencing), reflectiveobservation (examining), abstract conceptualization (explaining), and active experimentation(applying).Therefore, we designed a learning environment that requires students to use all of the styles.At the beginning, students read the given problem and search the related references. Beforedeveloping OBD implementation, students read the manufacturer datasheets and instrumentdescriptions from this course. They should complete a term report including: (1) aspecification that describes the

integrateddevelopment environment (IDE). Students can develop their embedded control applications inassembly, C, or C++ in CodeWarrior IDE. The microcontroller and CodeWarrior IDE arecovered in a number of references[1], [2], [7], [8], [11], [15] and [16]. The microcontroller and CodeWarriorIDE are available as a kit offered by Freescale Semiconductors. Individual modules are alsoavailable from other vendors. The kit contains a project board for flashing the microcontrollerand for electronic circuit prototyping. The kits were first used in our linear control systemscourse in fall 2006.The rest of this paper is organized as follows: Section II covers briefly the pedagogical approachfor the course. Section III briefly describes the embedded control courseware

beincluded in final implementations.A. Synchronized-Counter SynthesisOne of the synthesized source configurations is based on three synchronized four-bit up/downcounters. The basic plan for this configuration, as shown in the block diagram of Figure 1, wasto: • Create three appropriately phase-separated stepped-triangle waveforms, • Wave shape each triangle waveform into a stepped-sinusoid, and • Power amplify and low-pass filter each stepped sinusoid. Figure 1 Block diagram for synchronized counter low-voltage three-phase sourceFour-bit up/down counting was chosen for two basic reasons: • there are thirty counts (a number divisible by three) in each cycle of a four-bit up/down count cycle (0–15–0): achieving 120º phase

A recent report from the National Academy of Sciences, Risingabove the Gathering Storm, noted the declining numbers of American students pursuing STEMcareers, and the urgent need to reverse this trend, if a subsequent drop in U.S. economicdevelopment is to be averted.1 Additionally, a report by the Academic Competitiveness Councildetails goals and metrics for encouraging more American students to study STEM careers.2The NIST Summer Institute for Middle School Science Teachers evolved from an idea of Dr.HratchSemerjian, former NIST Chief Scientist, who wanted to support local educators by sharingNIST resources as a means to encourage more students to pursue

arecomputer programs, outdoor model testing, and indoor model testing, and then concludes with adiscussion of the implementation of laboratory-oriented design in undergraduate education.1. IntroductionDesign of daylighting systems in buildings is an energy saving strategy. When commercialbuildings rely more on natural light instead of electric light, they do not only save light energy,but also reduce the cost of air conditioning. That is mainly why daylight always occupies a highpriority on the list of energy conservation measures (ECMs) for commercial buildings. For thesame reason, integration of daylighting systems earns credit points for the LEED (Leadership inEnergy and Environmental Design) rating system1 and other similar rating systems of

- Objectives of the Experiment and the ProjectThe following major objectives were set at the inception of the project:1. To develop an experiment and project for a complete review and a better understanding of thestatistical parameters that may heavily influence the engineering/design decision making process.2. To create an opportunity for collaborative research and design efforts between undergraduateengineering student(s) and faculty.3. To design, produce, test, and optimize a cost-effective, reproducible apparatus withoutstanding features.4. To make all information necessary for fabrication of the apparatus and conducting theexperiment and the project available to engineering programs nationwide
