The motivation for increasing laboratory participation is detailed in this paper, and theimpact of these changes is discussed. Course and departmental goals and objectives, and relatedABET accreditation criteria are discussed, and the effectiveness of these efforts is assessed. Theaccommodation of undergraduate design-build-fly teams is discussed, and the potential for suchcompetitions to provide a more complete laboratory experience is assessed.BackgroundThe use of computational tools like Mathcad1 and programming environments such asMATLAB2 and LabVIEW3 have made it increasingly easy to program complex solutions toanalytical problems. However, the use of such
Session 1626 Design Experience in a Laboratory Environment Nagy N. Bengiamin Electrical Engineering Department University of North Dakota Grand Forks, NDAbstract - This paper addresses enhancing engineering design education via hands-on and open-ended laboratoryexperience. Design is considered in its broader context of problem solving attributes. A unique laboratory hasbeen developed, in the Electrical Engineering Department at the University of
Design Engineering and the Blended Learning Unit at the University of Hertfordshire, UK. Page 12.1568.1© American Society for Engineering Education, 2007 Using technology to support engineering laboratory studiesAbstractLearning requires activities that facilitate exploration, personal (first-hand) experience as wellas provide opportunities for students to develop and re-conceptualise their growingknowledge. Laboratory studies present an ideal opportunity for such personal action andreflection whilst also bringing some of the classroom activity to life. Although carefullyconsidered laboratory studies have the potential
energy systems. A design project isincorporated into this laboratory course. Currently, experiments performed in this laboratoryinclude a Jet Engine, Road Load Simulation, PEM Fuel Cell Performance, Centrifugal Pump,Fan Laws, Compressible Flow, Pipe Flow and Flow Meters, Lift and Drag, Heat Exchanger,and Cylinder Convection. Among other things, the students learn how jet engines work; howaircraft wings produce lift; how a fuel cell works; how supersonic velocities are produced; howto use a dynamometer to predict the gas mileage of a car; how to match pumps and fans to pipingsystems and ducts and how to cool hot objects effectively. They also learn to apply thefundamental principles of thermodynamics, fluid mechanics and heat transfer in an

Although not independently measured, the student self-reported confidence in the topics explored indicates improved learning as part of the modules.ConclusionsAn inexpensive experiment was created that combines bending modules with attached straingages and a Wheatstone bridge circuit connected to an oscilloscope. It was designed such thatwhen the bending module was deflected, a change of voltage would appear on the oscilloscopeand the macrostrain could be calculated and visualized. 12Students in circuits laboratory tested this module in the Fall of 2016 and Spring semester of 2017and the educational methodology was a success. Students, especially

They then apply Ackermann's formula to obtain the state feedbackgains to place the closed loop poles at locations suggested by the professor. Third, we present astate feedback control experiment based on a two degree of freedom mass-spring system withrigid body mode. Control of this device is analogous to control through a flexible manipulator,except that the system is simplified to one-dimensional motion.

, they cannot alwaysaccount for all the details that must be considered in designing and analyzing a physical systemin an interdisciplinary, team-oriented environment. The need to control real hardware, and notjust simulations, is known to all who design and build real control systems. Experimentation iswidely accepted as an important part of control-system education1. Arzen, et al.2 describe thedevelopment of a control laboratory using real, rather than simulated processes. Their articlepresents the approach that the Department of Automatic Control at Lund Institute of Technologyuses to maintain a high level of practical laboratory experiments. They claim that real-timesystems help the students understand the theoretical material and they also
Digital Audio Editor. Page 11.797.42.2 Laboratory ExercisesStudents entered Signals and Systems with a basic knowledge of MATLAB and a fundamentalunderstanding of test and measurement equipment. However, they had no experience withSIMULINK programming or with the DSP hardware used in the laboratory. As this courseprovided an introduction to signal processing and system design, they also had no priorknowledge of these topics.Four laboratory exercises were developed for the pilot offering in the Fall of 2005 and aredescribed in the following sections. The exercises included Digital Audio Effects, a Dual-ToneMulti-Frequency System, a Voice Scrambler
theoreticalmodels to experimental data, and to develop an approach to analyzing and designing complexengineering systems. The second goals are laboratory-specific: to introduce methods ofmeasurement and instrumentation, to collect, organize, analyze, and interpret data, and todevelop an approach to engineering experimentation. Woven into these goals is the objective ofpromoting teamwork, communication skills (written and oral), and at the same time achievinglearning objectives like those of Bloom’s Taxonomy1. The difficulty of attaining such a diverse set of objectives can lead to some goals beingunderemphasized – often, ironically, the laboratory-specific goals. Frequently, the complexity ofan experiment, and the sheer amount of data collected
