These methodsinclude bang-bang control, fuzzy logic control, neural network control, PID adaptive control,robust control, hybrid control, predictive control, and feed-forward control. 3 Because of thisversatility, both the DC Motor and inverted pendulum systems will be used as the basis for the kitbeing developed

Hands-on laboratories that feature realmeasurements could allow students to probe the dynamics of realistic systems, therebystrengthening their conceptual understanding2, 7, 8. However, the prohibitive cost of equipmentand shortage of laboratory space limits these options.Our project aims to overcome these challenges by utilizing a new, highly portable andinexpensive technology, which we call interactive-Newton (i-Newton). The i-Newton can engagestudents in the experiential learning of dynamics outside the confines of the traditional lecture-based teaching methods.The objectives of the project we describe in this paper are to: 1. Investigate whether i-Newton has an effect on students’ conceptual

The sophomore-level coursein signal processing is required of all engineering majors and provides a foundation in themathematical modeling and analysis of signals and of linear time-invariant systems. Thelaboratory component of the course utilizes applications of signal processing to motivate thebreadth of the field which includes filters, AM modulation, and Nyquist sampling theory. In thisstudy, both the TMS320C6713 DSK development board with its 225MHz processor and thenewer Beagleboard-xM with its 1 GHz processer provide students with a real-time,programmable signal-processing hardware platform that enhances the learning experience.

The results from this quick review, as summarized in Table I, indicatethat, in both sources, more efforts on time-domain methods were reported than those onfrequency-domain methods, confirming the discrepancy between the existing efforts in the time-and frequency domain. Moreover, few publications returned from these two searches directlyaddressed the abovementioned concern [1-9].TABLE I Time

Some variation has been made to the goals but the overall scope of theproject has not changed. The goals are: to develop a meaningful three-phase system for sophomore engineering students who have only introductory knowledge of three-phase power to improve student knowledge concerning the basics of those systems to give the students increased confidence in applying the knowledge obtained to work at

The current lab activities have evolved from those thatwere developed in the late 1980s and partially outlined in a paper by Kaminski (1) in 2001.In reviewing the literature on the topic of fluids lab activities it becomes apparent that manyengineering programs bundle fluids labs with thermodynamics labs and sometimes also includeother topics often as a single lab class far removed from the original lecture section (2). Whilethese topics do have significant interactions there is a limit to the number of topics that can beexplored by bundling them into one lab class. In the

A long-term design project that integrates knowledge from multiple courses strengthens student knowledge retention. 2. A large-scale design project requiring tools from many courses improves student problem-solving and design skills.By integrating five semesters of the mechanical engineering curriculum into a cohesive whole,this project has the potential to transform the way undergraduate education is delivered. Beforeand after testing is being conducted to assess: a) Change in retention between courses and b)Change in student problem-solving and design skills.The centerpiece of the hybrid powertrain is
similarities in syntax. While teaching MATLAB as an introduction toprogramming is not new7, direct interfacing between MATLAB and hardware still remains non-trivial. For example, using MATLAB to operate an Arduino microcontroller requires Simulink,which adds another layer of complexity. By design, ECE 103 avoids overly theoretical computerscience topics to focus on practical techniques that would be of value to electrical engineers.

Visualization of three-dimensionalstructures and crystallographic directions by first year engineering students often poses achallenge as textbooks and other learning materials can utilize only two dimensional depictions.This tutorial activity allows students to build crystal structures, and to examine and comparethem.In the past, other researchers had conducted a similar activity to support student learning.Published in 1952, Hatch, R.A., et.al [1] used hollow plastic balls for crystal structureconstruction in order to facilitate x-ray crystallography and crystal chemistry teaching.

Linear Circuits had alaboratory component that met bi-weekly, Electronics 1 had a weekly laboratory, and Signalsand Systems had no laboratory at all. The first and third courses were assigned 3 credit hours, thesecond 4 credit hours. In this scenario, the students viewed each course as its own entity andfrequently did not make the connections between the concepts in each. Electronics 1 wouldrequire a massive review of basic circuit concepts, and students did not see how Signals andSystems was anything other than a straight mathematics course, with no relevance to workingwith real devices.All electrical and computer engineering students study

In theprocess, students must identify testable and quantifiable attributes of the product, repeatcontrolled measurements, and build confidence in their outcomes. At the end, the teams mustweigh results to recommend a superior brand. While the project is designed to be student-driven,there are several milestones to guide their progress. These milestones are elaborated below usingan example of ‘superglue’ as a product of choice by a typical student team (See Fig. 1). Theinstructor

Capstone teams are particularly valuable fordeveloping equipment for labs that are small, for elective courses, and for courses that need a Page 26.1414.3hands on component without having a physical lab space.

The freshman design course (CE 195) with 50 students (about eight groups of six) addressed a preliminary design of a pipeline network (Figure 3 and 4) that crossed an active fault line. They studied the impact of a rupture of this fault on the pipeline. They participated in the preparation and testing of a four-point pipe bending tests. The junior structural laboratory course (CE 382) with eighteen students (about four in a group) analyzed the laboratory pipe test arrangement (Figure 5) using SAP2000 software with the pipe element as a structural element.

Critical Operations curriculum. The goal ofthe curriculum is to provide industry with a workforce that has the electrical, mechanical, andinformation technology skills necessary to support critical operations in the healthcare, datacenter, automated manufacturing, and energy sectors. [1] One goal of the work is thedevelopment of remote automation exercises that would enable geographically distributedstudents access to valuable electromechanical and programming lab experiences. [2,3] Anothergoal is to introduce them to remote troubleshooting, where their initial corrective or investigativeactions would be taken from a remote control station instead of in proximity to the actual setup.[4,5]The electromechanical systems chosen for these exercises
described here was designed to eliminateoutdated or overly canned experiments, while choosing robust equipment that the students couldinteract with in a much more open-ended way.Measurement and Analysis is a required course for junior level mechanical engineers. Theoverall purpose of the course is to teach students how to design experiments, how to measurecommon engineering variables, and how to use and select sensors. The experiment in question isdesigned to teach students how to measure strain. Students are asked to investigate the effect ofdifferent numbers of strain gauges on the output of a Wheatstone bridge circuit, and observe therelationship between physical location on the object and location in the circuit.

The initial focus ofdelivering lab education to satellite campuses is the junior thermal fluids lab on measurementtechniques. There are three styles of laboratory experiments throughout engineering education: hands-on,simulation, and remote (or virtual) labs.1-7 Hands-on experiments allow student to physicallymanipulate components and gather data. Simulations use computer software to emulate the resultsgathered in a real laboratory setting. Simulations can be successfully used to explain and reinforcephysical concepts, but limit the capability for true experimentation. Remote labs use the positivefeatures of both hands-on and simulation
layers and separate them from the platform. Figure 1 shows an example ofcatastrophic failure where parts of the extruder were engulfed in plastic. In this case, the 3Dprinter was left unattended overnight since the time predicted by the 3D-printing program tocreate a part was about 9 hours. As the first few layers were deposited, they separated from theprinting platform and adhered to the printing nozzle of the extruder. Then, the nozzle and someportions of the extruder were encapsulated as more plastic was extruded. To remove the plasticbuild-up, a student used a heat gun to re-melt the plastic and release the extruder. However, inthe process, a plastic extruder holder was partially melted as well and had to be replaced. Figure1a shows the
