VLs then offer a viable wayfor an institution to expose its students to far more laboratory experiment by sharing resourcesand equipments of other local or foreign institutions.The role that VLs can play in addressing the weak experimentation component of education in Page 13.426.2developing countries has only recently become a research problem of interest. Consequently,very few VL architectures are designed or optimized for the low bandwidth environments thatcharacterize educational institutions in countries like Nigeria. One of the few VL

This lab allows students to make theconnection between the concepts of first order modeling in the control system classroomlectures2 and ultimately, apply them in the laboratory to the real world systems.Students in this lab demonstrate achievement of numerous a-k ABET criteria. The followingABET outcomes can be assessed in this lab:a. “An ability to apply knowledge of mathematics, science, and engineering.”b. “An ability to design and conduct experiments as well as interpret data.”d. “An ability to function on multidisciplinary teams.”e. “An ability to identify, formulate, and solve engineering problems.”g. “An ability to communicate effectively,” by preparing a formal report.k. “ An ability

Performanceon the other criteria was roughly similar in the two sets of courses, suggesting that both theprevious projects and the new Grand-Challenge projects significantly contributed to students’understanding and ability to apply course material.We emphasize, however, that this particular set of outcomes would be unlikely to capturepositive contributions results of the changes made to the laboratory projects. In other words, thefive criteria to which the MOs and LOs are mapped – a) apply knowledge of science,mathematics, and engineering, b) design and conduct experiments and analyze and interpretdata, c) design a system, component, or process to meet desired

Thesound system is still a work in progress, driving micro speakers requires special attention tofiltering out low frequencies. Perceived audio will be low if this is not done.Pedagogical ContextHandheld gaming consoles comprise multiple systems. For this reason, it is recommended that thisproject be split into various experiments and teaching opportunities. For example, this projectcould supplement a related course, or extracurricular activity. The design and components are fordemonstration and are completely subjective. It is encouraged to personalize and or deviate fromthe demonstrated design in order to foster

When assignments contain words such as calculate, design,or draw students tend to have approving body language while the assignment is being handedout. Replace one of those words with format, write, or present, and body language often changesto indifference, concern, or overall lack of interest/approval.Laboratories are an opportunity to interface what are often less desirable activities (e.g. writingand presenting) with physical experiments and calculations. Laboratories can also be anexcellent venue to maximize active learning opportunities, as it is well known that activelearning can be beneficial to students. As such

This knowledge and experiencewill result in a well-educated graduate with practical hands-on experience designing,configuring, and troubleshooting industrial control systems, with an obvious benefit toemployers of these graduates.Newly Equipped Industrial Control and Automation LaboratoryGenerous gift of Nucor provided to Michigan Tech made it possible to equip the new IndustrialControl and Automation Laboratory with state-of-the-art Programmable Logic Controllers andMechatronics stations integrated with FANUC robots. The authors conducted significantresearch on the type of equipment, as well as vendors producing this equipment to ensure thatnewly
students are exposed to normally-open, normally-closed contact types, relays and ladder diagrams. Therefore, we designed and built custom pieces of hardware and mailed them to each remote site. This is the only experiment that does not require remote control and programming of hardware over the Internet. Students explore the contacttypes with the built-in multimeter and wire the board to implement the control logic.

also allowsfor the majority of class time to be used on the exercises themselves, rather than in the lab setupas with some laboratories that rely on complex equipment. Because toys are used in the labs, theease and timeliness with which lab configurations can be changed has provided the opportunityfor professors to cover multiple experiments in a single class period. This also allows thestudents to rapidly change lab configurations when trying to solve a problem.Dynamics Course LayoutThe topics covered in lecture portion of this course are based on the text book Dynamics:Analysis and Design of Systems in Motion, 2nd Edition.10 The subjects that are covered in thiscourse are as follows: ● Motion of translating bodies ● Inertial Response of

University CourseVillanova University has a two-semester senior track elective in the high frequency systems areathat is a follow up to the required second semester junior year electromagnetics class. This classuses the textbook 'Microwave Engineering' by David Pozar (4th ed) [2]. Both courses have asignificant laboratory component where the students learn to design, fabricate and test variousactive and passive microwave circuits including matching networks, filters, amplifiers, andmixers. The Cadence Microwave Office suite of tools is used under their university program [3]for the CAD portion of the design flow, and, for the first time in the 2020/2021 academic year,the students were provided a nanoVNA as part of their laboratory kit.Because of the

The objectsbeing tested are simple shapes and offer limited opportunity for creative experimentation. Wewish to enhance this experience by offering our students the opportunity to design and testoriginal aerodynamic models, such as automobile body shapes. This has motivated aninvestigation of alternative methods for rapidly producing wind tunnel models of originaldesigns. Two fundamentally different approaches are considered: (1) molding/casting of modelsstarting from a rough physical prototype and (2) creation of functional physical models from adigital image.Molding

This means thesoftware is reliable and that some damping was present in the resonator. The damping could bedue to the viscosity of air or the fabrication techniques used. We wanted to investigate thismatter further. In the fall of 2009 each student team was asked to design three resonators torespond at 1000 Hz, for consistency and comparison with the earlier results, using differentmetals. The students learned to use SpectraPlus as part of the laboratory activity. They wereable to obtain several time domain data and generate the frequency response and 3-D surfaceplots. Each team submitted a

The students were required to read andcomprehend the proposed physical model and experiment procedure outlined in the originalpaper. They then had to adapt it to the available equipment in our university laboratory. Oncethe teams had collected data, they were to analyze and compare it with the physical modelingof the observed phenomenon. Finally, they were to create a self-explanatory videopresentation, limited to 10 minutes, where the student teams explained the physicalphenomenon, the modeling, the experiment conducted, and the analysis and conclusionsdrawn. The PBL approach allows students to have a better understanding of importantphysical theories

design basis for developmentof Interactive Virtual Laboratories in thermodynamics. Thermodynamics is a difficult subject forchemical and biological engineering students to master. One reason for the difficulty is thediverse and challenging set of threshold concepts that they must coherently synthesize and beable to apply in a diverse range of contexts. Based on our experience and from reports in theliterature, we have identified a set of threshold concepts we propose are critical for mastery ofthermodynamics. To help students better learn these concepts, we have been developingInteractive Virtual Laboratories. This paper describes the development and initial investigationof two such laboratories.

This is particularly important as it is common inengineering practice.This paper describes a laboratory exercise in which students measure the performancecharacteristics of small water pumps. The principal measurements are the variation of head rise(as manifested in the pumping height of water) and the corresponding volume flow rate whileoperating at a fixed rotating speed. Experiments based on this apparatus can be employed in avariety of courses and with students at various levels. The author developed this experimentwhile teaching a graduate level course on
