In this paper, a model STEM program called Engineering Heroes: Qatar Special Investigators (QSI), aimed to familiarize young students with science and engineering in real life applications, is presented. The program theme is about forensic science and technology, which included science and engineering activities with hands-on projects to challenge students’ science and critical thinking skills. Throughout the program, students learned about forensic science as an application of science, engineering and technology to collect, preserve, and analyze evidence to be used in the course of a legal investigation. Participants learned the history of forensic analysis and how it evolved into today’s specialized career field. Forensic specialists include backgrounds in chemistry, physics, biology, toxicology, chemical and electrical engineering. Topics included in the program were a study of toxicology and chemical analysis, assays to determine drug contents, fingerprint development, environmental contamination, chromatography in forgery, presumptive vs. confirmatory testing, scanning electron microscopy, infrared analysis, and evidence handling techniques. The details of the program are presented, including the contents, preparation, materials used, case studies, and final crime scene investigation, which featured the learning outcomes.

The Grove City College (GCC) European Study Center (ESC) is a program that allows mechanical and electrical engineering students to study abroad in the junior and senior year fall semester, respectively, and graduate in four years. The ESC is activity partners with a local institution called Oniris, which specializes in food science engineering, and veterinary science (an affiliate with the French Ministry of Agriculture). Electrical engineering students that participate in the program carry out their yearlong capstone design project (Senior Experience in Electrical Design (SEED)) in partnership with Oniris. For the 2016–2017 academic year, participating electrical engineering students completed a project titled Ultra-Low-Cost Flexible Sensor Array, or “Low-Cost Array” (LCA), designed for commercial tunnel-style ovens. The LCA features low cost ($200), flexible programmability, and ease of use (based on the widely available Arduino). The purpose of the project was to develop a low-cost data-logger to operate inside tunnel-style ovens to record temperature from thermocouples (and other analog signals, i.e. heat flux) for thirty minutes in an environment up to 250 °C. This study evaluates the LCA compared to other data-logging systems, and its performance in high temperature environments by a series of experiments. In addition, an idea of its commercialization potential was explored by interviewing industrialists and academics on-site. Experimental results showed that: (1) data logged from the system were close to values recorded by current systems used for both temperature and heat flux measurements, and (2) the system performed well at 240 °C for thirty minutes (maximum temperature of oven). In addition, the interviews revealed that although most interest was in a tunnel-style oven data-logger, it seems feasible to incorporate changes to satisfy needs for other markets, especially those of a general-purpose data-logger.

Developing countries are mostly reliant on external technologies and this augments the need for systems engineering capability in these economies. It is therefore imperative that systems engineering as theory and practice is included in undergraduate engineering curricula to strengthen the internal technological capability of a country’s developing engineers. In South Africa, the quality of undergraduate engineering programs is governed by the Engineering Council of South Africa (affiliated under the Washington Accord); and the exit level outcomes of the programs are predetermined explicitly per module. Systems engineering was introduced to an undergraduate electrical engineering program offered in the Faculty of Engineering and the Built Environment at the University of Johannesburg; and a framework developed to ensure that the program still meets the requisite ECSA exit level outcomes and therefore international standards. This paper presents the design and implementation of the framework, as well as the challenges that students are exposed to when faced with real-world systems engineering practice. Students were grouped into independent product development teams using a software support tool which promotes diversity and skill-level targets for each team. The independent team structure required the use and application of the systems engineering process and supported the development of management and communication skills. Furthermore, the framework allowed assessment of the performance of each product development team towards achieving the overall project objectives. One of the accreditation requirements of undergraduate engineering programs is peer assessment and this was achieved by the process. The paper closes by presenting the results of the stated framework implementation in an undergraduate electrical engineering program offered in the Faculty of Engineering and the Built Environment at the University of Johannesburg.

The 3rd year Electrical Engineering Design Studio (EEDS) course is a project-based learning (PBL) course that gives students hands-on experience with putting electrical engineering principles into practice. It is an electro-mechanical project which provides a particular challenge since electrical engineering students often lack mechanical design skills. It is found here that learning outcomes are improved by a 2-stage formative assessment and time optimization strategy that allows students to extract as much value as possible out of the limited time they have to devote to this exercise. It consists of an innovative assessment strategy that includes formal, informal and self-assessments, and an innovative budgeting, lecture scheduling, parts distribution, and order queueing system. The impact on efficiency is shown through an end-of-term student survey and a subjective evaluation of their work, in comparison to the previous year.

The EcoCAR 3 competition is the latest iteration of the Advanced Vehicle Technology Competitions sponsored by General Motors (GM) and the Department of Energy (DOE). The competition involves 16 universities from the US and Canada and requires the teams to design, develop, and implement a hybrid Chevrolet Camaro from the platform of GM’s choosing. The Colorado State University (CSU) team is a unique participant in this competition because it implements the program as a subset of the Mechanical Engineering and Electrical Engineering senior capstone courses. The advantages of this arrangement are that EcoCAR 3 can leverage course deliverables to achieve EcoCAR 3 objectives, and that students can receive credit for their efforts in support of the EcoCAR 3 program. The challenges with this approach center around having two sets of deliverables (competition and academic) on overlapping timelines with shared resources. These challenges must be resolved through project management activities to successfully meet all of the deadlines and requirements of each program.

The University of Connecticut Department of Mechanical Engineering has developed an industry recognized Senior Design Capstone course. The course provides fourth-year students the opportunity for a “major design experience in which they apply the principles of engineering, basic sciences, and mathematics to model, analyze, design, and realize physical systems, components or processes, and it prepares students to work professionally” [1]. The course is taught by a class instructor and is supported by the faculty of the Mechanical Engineering department at UConn. In the 2013–2014 academic year there were over 40 projects in the course. This paper presents the issues and challenges that students faced when working on a project for Koffee Karousel’s coin-operated K-Cup vending machine. Work on the project began with the problem statement, and was followed by the generation of possible solutions (accepting the most promising ones) and finally, choosing the ideal solution. The subsequent steps involved preliminary and detailed design, structural analysis, creating a 3D CAD representation, generating drawings, and producing a prototype. The prototype was then tested to verify its capabilities. The example of switching from a coin-operated design, with its limited potential use, to an electronically operated solution is described in this paper. The objective of this senior design project was to implement a credit card reader onto the original Koffee Karousel design. To accomplish this goal, a redesign of the Koffee-Karousel’s coin mechanism was required. An electrical engineering team of four students worked independently on the credit card and display setup, while a mechanical team worked on a lever mechanism and gears activated by the validation of a credit card. The implementation of this new mechanism included designing a replacement face, a couple of brackets for electrical hardware, and several new parts, including an actuator and a mini-stepper motor. In addition, students designed the new cam that would interface with stepper motor. Some parts were accepted from the current design of the lever and ejector. The new design still allows the customer to choose which K-Cup flavor they want by hand by operating a rotating knob at the top of the carousel, but no longer requires the user to trigger the ejector mechanism manually. Students tested the new mechanism to ensure it was not only efficient, but also worked properly. The stresses on each individual part were calculated for the first design iteration to ensure the new design would not yield or fail over time due to fatigue. The project and its challenges are described in this paper, as well as the students’ contributions to the design of the Karousel mechanisms, switching it from a purely mechanical to a mechatronik solution.

Increasing demands on the productivity of complex systems, such as machine tools and their steadily growing technological importance will require the application of new methods in the product development process. This paper shows that the analysis of the simulation results from the simulation based mechatronic model of a complex system followed by a procedure that allows a better understanding of the dynamic behavior and interactions of the components. Mechatronics is a design philosophy, which is an integrating approach to engineering design. Through a mechanism of simulating interdisciplinary ideas and techniques, mechatronics provides ideal conditions to raise the synergy, thereby providing a catalytic effect for the new solutions to technically complex situations. This paper shows how the mechatronic products can exhibit performance characteristics that were previously difficult to achieve without the synergistic combination. The paper further examines an approach used in modeling, simulation and optimization of dynamic machine tools and adopts it for general optimized design of mechatronics instrumentation and portable products. By considering the machine tool as a complete mechatronic system, which can be broken down into subsystems, forms the fundamental basis for the procedure. Starting from this point of view it is necessary to establish appropriate simulation models, which are capable of representing the relevant properties of the subsystems and the dynamic interactions between the machine components. Many real-world systems can be modeled by the mass-spring-damper system and hence considering one such system, namely Mechatronics Technology Demonstrator (MTD) is discussed here. MTD is a portable low cost, technology demonstrator, developed and refined by the authors. It is suitable for studying the key elements of mechatronic systems including; mechanical system dynamics, sensors, actuators, computer interfacing, and application development. An important characteristic of mechatronic devices and systems is their built-in intelligence that results through a combination of precision, mechanical and electrical engineering, and real time programming integrated to the design process. The synergy can be generated by the right combination of parameters, that is, the final product can be better than just the sum of its parts. The paper highlights design optimization of several mechatronic products using the procedures derived by the use of mass spring damper based mechatronic system. The paper shows step by step development of a mechatronic product and the use of embedded software for portability of hand held equipment. A LabVIEW based platform was used as a control tool to control the MTD, perform data acquisition, post-processing, and optimization. In addition to the use of LabVIEW software, the use of embedded control system has been proposed for real-time control and optimization of the mass-spring-damper system. Integrating embedded control system with the mass-spring-damper system makes the MTD a multi-concepts Mechatronics platform. This allows interface with external sensors and actuators with closed-loop control and real-time monitoring of the physical system. This teaches students the skill set required for embedded control: design control algorithms (model-based embedded control software development, signal processing, communications), Computer Software (real-time computation, multitasking, interrupts), Computer hardware (interfacing, peripherals, memory constraints), and System Performance Optimization. This approach of deriving a mathematical model of system to be controlled, developing simulation model of the system, and using embedded control for rapid prototyping and optimization, will practically speed product development and improve productivity of complex systems.

Often when people who are not in the field hear about electronic packaging, they immediately presume that it is exclusive to electrical engineering; however, electronic packaging has opportunities for many different Science, Technology, Engineering, and Mathematics (STEM) areas. Many projects in micro- and nanotechnology are interdisciplinary in nature, and thus, a broad background of various disciplines is needed to conduct research and development in these areas. At the Georgia Institute of Technology, an initiative called the Meindl Legacy project has been created to use crowd funding to help graduate students in the nanotechnology area to create “teachable moments.” The intention of the teachable moment is to broaden the research to younger audiences, so that they are inspired to take the necessary background classes needed to pursue a STEM career path. The use of crowd-funding allows for industry partners and the general public to become involved with research that is currently ongoing at the Georgia Institute of Technology and to educate K-12 students. The “teachable moment” outlined in this paper was created to demonstrate how different materials’ coefficients of thermal expansion can affect the interfaces and potentially lead to cracking damage in an electronic package.

Vanderbilt University introduced a new course in the 2012 Fall Semester: Cyber-physical vehicle modeling, design and development . This course focused on the design, development, fabrication, verification, and validation of a scale vehicle in the virtual and the physical domains to meet a set of realistic and challenging design requirements for the Defense Advanced Research Projects Agency’s Model-Based Amphibious Racing Challenge. The students built a series of models in software and hardware to guide the design choices for the 1/5th scale amphibious vehicle. The culmination of this course was a competition against teams from other universities in January 2013 that compared the vehicle’s actual performance with student-created simulation models. This was an elective course outside the traditional capstone design curriculum and consisted of a team of juniors and seniors across the disciplines of mechanical engineering, electrical engineering, computer engineering, computer science, and physics. The students received robust training “to be an engineer” with many activities that can’t be included in a typical classroom environment: hands-on experience designing, modeling, and building a complete vehicle; simultaneously solving several open ended, rigid deadline challenges; and navigating complex team dynamics in a full end-to-end project. Additionally, the students gained experience using modern engineering modeling tools from the Defense Advanced Research Projects Agency’s META tool suite under development for the Fast, Adaptable, Next-Generation Ground Vehicle program. The META tool suite is a set of free, open source tools for compositional design synthesis at multiple levels of abstraction, design trade space exploration, metrics assessment, and probabilistic verification of system correctness. This work details the course activities and summarizes the lessons learned from a pedagogy perspective.

Engineering education has the objective of not only presenting the scientific principles, i.e., engineering science, but also of teaching students how to apply these to real problems. Therefore, hands-on laboratories have been an integral part of the engineering curriculum since its inception [1–3]. This presentation will demonstrate the use of a novel low-cost experimental apparatus for use in a typical undergraduate course in control systems taught to mechanical engineering students, i.e. students with limited exposure to electrical engineering. A simple to use, low cost system has been designed that provides a platform for experimentation in areas from basic open loop control, to frequency domain and digital control systems. This paper presents the design of the system, and demonstrates the ability of MATLAB tools such as Simulink Real Time Windows Target to illustrate implementation of various aspects of control design. The system setup consists of a DC micro-motor attached to a carbon fiber rod. The angular displacement is measured with an analog potentiometer, which acts as the pivot point for the carbon fiber rod. The DC micro-motor is powered by a low cost, custom circuit board, whos H-bridge allows the motor rotate in either forward or reverse directions. Attached to the micro-motor is a small propeller, providing thrust force to rotate the pendulum about its potentiometer. The circuit board communicates to the host computer using the USB protocol, utilizing usbser.sys to create a virtual COM port. MATLAB uses the serial port object to read and write from the control board. The control board is powered through two USB ports, requiring no external power adaptor or extra cabling. This paper shows the use of feedback linearization to arrive at a system where classical linear control design methods can be used. The project was tested in a classical control systems design class offered to senior-level mechanical engineering students. Student feedback and survey data on the effectiveness of the module is also presented.

Recent engineering education research has suggested that most engineering curricula does not promote attainment of many characteristics desired in practicing engineers [1][2]. One such characteristic is effective communication with workers in other disciplines. A method to attain improved communication is simulation of workplace situations in the educational environment [3][4]. In an effort to improve communication between trades and to foster a higher appreciation for the other field, a project simulating the working relationship between engineers and machinists was implemented via a joint semester project coupling a Computer Numerical Control (CNC) machining course and an engineering design course. A significant body of knowledge exists regarding multidisciplinary education for engineering students. Nearly all of the multidisciplinary projects involve one discipline of engineering working with another engineering discipline (i.e. mechanical engineering students working with electrical engineering students). The multidisciplinary work between different disciplines of engineering students has documented benefits; however, the two groups of students are on a similar communication level. By coupling junior and senior level bachelor degree-seeking engineering students with students primarily pursuing a 1 year CNC machining certificate, many communication barriers are encountered that are not seen in typical university multidisciplinary projects. The students from the engineering class were tasked with designing a simple assembly that performs a specified function. The engineering student was responsible for generating a complete set of manufacturing prints. Each engineering student was matched with a group of two or three CNC machining students, who were responsible for manufacturing the parts designed by the engineering student. This type of collaboration closely simulates the design engineer working with the manufacturing shop floor employee in determining how a part is best produced and taking the project to completion by manufacturing and assembly of that part. Data collection methods included student surveys and instructor observations. Primary student outcomes appeared to be; 1) an appreciation for the importance of communication and, 2) greater understanding of the complete process needed to produce a product. The primary difficulties the students encountered were due to communication issues and project management breakdowns. Efforts to address these issues and other lessons learned will be discussed.

Students working toward a baccalaureate degree in Mechanical/Electrical Engineering Technology at the University of Cincinnati are required to complete a “Design, Build, and Test” senior capstone design project. Some of these capstone design projects are done in collaboration with industries to meet their needs. One of the projects during 2009–2010 academic year is to meet the needs of the packaging industry. The student team will design and recommend a specialized End of Arm Tool for palletizing applications. They will build a scaled model and the industrial sponsor may build the full product at the later date. A team of three students from Mechanical Engineering Technology at the University of Cincinnati are working on this project, which gives them an opportunity to showcase the knowledge and skills learned in their coursework and during the co-op (cooperative) experience, as well as to develop the additional skills needed to be successful in a team oriented business world. This team is working on a technically complex project from concept-to-design, build, test, and then to have the possibility of their product being used in commercial applications. This paper will give a description of the MET senior capstone design course sequence at University of Cincinnati and the list of pre-requisites for the capstone design sequence. It will also describe the design of 2009–2010 End of Arm Tool (EOAT) project and the plans for building a scaled model. Included too, is a description of how Industry-University Collaboration can improve student learning.

Electrical Engineering is one of the leading fields in the professional working world. Every day a novel idea is being adapted into the program to insure the progression of the students and to increase the possibility of the learning experience. Active Teaching methods are today’s leading approach in educational enhancement. We at Taibah University have successfully ran a course (GE 102: Introduction to Engineering Design) via the method of active teaching approach. Adopting these methods on Electric Circuit 1, Digital Design 1, Electronics 1, Signals and Systems, and Power System Analysis 1 courses at the second year program studies will advances the students learning capabilities. For those students who successfully complete these courses will advance into the third year at the program. To assure a 100% retention rate, we promote a gate in association with the vocational college to accept those students who would fail the completion of this year in a smooth manor with their program and graduate from the vocational college.

The capstone course in Mechanical engineering at North Carolina A&T State University (NCA&TSU) is divided into two semesters. Team design projects begin in the fall semester and continued during the following spring semester. North Carolina State University, we, like virtually all other engineering programs, require a capstone course involving a major design project. This year a team of four mechanical engineering students and two electrical engineering students has decided to design and build a fuel efficient hydrogen fuel cell vehicle to compete in the 2009 Shell Eco-Marathon. The competition is designed to provide engineering students with a real life design experience. The objective of the competition is to encourage innovation and foster the development of sustainable mobility. Participants can design a vehicle for the Prototype Group or the Urban Concept Group. The Prototype Group allows maximum technical creativity, while imposing minimum design restrictions. The Urban Concept Group is closer to actual road going vehicles and addresses current transportation requirements. Both groups must meet the design criteria and meet safety standards provided by the 2009 Shell Eco-Marathon Official Rules. Participants must also select from a list of Shell approved energy sources to power their vehicles. The list includes both traditional fuels and alternative fuels. The main objective of the competition is maximum fuel efficiency. This year NCA&T Shell Eco-Marathon team has decided to enter the Prototype Group and has selected Hydrogen as the energy source. Our team placed in the third place in the hydrogen fuel cell prototype group. The completion of the Shell Eco-Marathon design project will serves as a valuable learning experience, while demonstrating the technical abilities of the students.

The domain of Electrical Computer-Aided Design and Engineering (ECAD/ECAE) has been subject to major and rapid change over the past couple of years. Electrical Engineering Computer-Aided Design (CAD) tools developed in the early to mid-1990s no longer meet future requirements. Consequently, a new generation of Electrical Engineering CAD systems has been under development for about a decade now. An overview of advances in this field is presented in the introductory part of this paper. This overview also sets the context and provides background information for the main topic, MCAD-ECAD-integration, to be addressed in the remainder of this paper. Many complex engineered systems encompass mechanical as well as electrical engineering components. Unfortunately, contemporary CAE environments do not provide a sufficient degree of integration in order to allow for multi-disciplinary product modeling and bi-directional information flow (i.e. automated design modifications on either side) between mechanical and electrical CAD domains. Overcoming this barrier of systems integration would release a tremendous efficiency potential with regard to the efficient development of multidisciplinary product platforms and configurations. An overview of the state-of-the-art in MCAD-ECAD integration is presented. In addition, associated research questions are postulated and potential future research perspectives discussed.

An undergraduate team consisting of mechanical and electrical engineering students at the University of North Dakota developed an electro-optical and un-cooled thermal infrared digital imaging remote sensing payload for an Unmanned Aerial Vehicle (UAV). The first iteration of the payload design began in the fall of 2005 and the inaugural flight tests took place at Camp Ripley, Minnesota, a National Guard facility, in the fall of 2006 with a corporate partner. The second iteration design with increased performance in object tracking and data processing is expected to fly in the summer of 2007. Payload development for integration into a UAV is a process that is not currently well defined by industrial practices or regulated by government. These processes are a significant part of the research being conducted in order to define the “best practices.” The emerging field of UAVs generates tremendous interest and serves to attract quality students into the research. As with many emerging technologies there are many new exciting developments, however, the fundamentals taught in core courses are still critical to the process and serve as the basis of the system. In this manner, the program stimulates innovative design while maintaining a solid connection to undergraduate courses and illustrates the importance of advanced courses. The payload development was guided by off-the-shelf components and software using a systems engineering methodology throughout the project. Many of the design and payload flight constraints were based on external factors, such as difficulties with access to airspace, weather-related delays, and ITAR restrictions on hardware. Overall, the research project continues to be a tremendous experiential learning activity for mechanical and electrical engineering students, as well as for the faculty members. The process has been extremely successful in enhancing the expertise in systems engineering and design in the students and developing the UAV payload design knowledge base and necessary infrastructure at the university.

This paper discusses the design, analysis and implementation of a faculty evaluation system to be used in both departments of Electrical Engineering Technology and Manufacturing Engineering Technologies and Supervision at Purdue University Calumet. The System, based on a faculty member’s continuous improvement plan, builds on the Management-by-Objectives approach, which reflects the Human Resource practice of performance plans and evaluations in corporate America. This new system, being outcome based, asks faculty to set goals and objectives with some degree of flexibility and is in line with the accreditation requirement changes of Accreditation Board for Engineering and Technology (ABET).

A unique course in the theory, testing and manufacturing of fuel cells has been developed at Arizona State University in the College of Technology and Applied Sciences. The course is designed for the engineering technology graduate students, but is also accessible to advanced undergraduates. The interdisciplinary nature of the course necessitates a team-teaching approach, and faculty with backgrounds in electrochemistry, electrical engineering and mechanical engineering deliver portions of the course. The course includes a theoretical portion, but also contains a comprehensive practical portion in which the students build a membrane electrode assembly and assemble, test and characterize this assembly as a single stage proton exchange membrane fuel cell. Feedback from the students indicates a great deal of excitement over the course, and has resulted in several students deciding to concentrate their graduate work in the fuel cell area. The paper describes the first course offering in the spring of 2003.

In the Mechanical Engineering Technology (MET) program at Indiana University - Purdue University Indianapolis (IUPUI), all bachelor degree students are required to take a course in Instrumentation. This course includes material on measuring and controlling mechanical parameters such as temperature, pressure and flow. Students are taught the basis of feedback control systems, primarily proportional-integral-derivative (PID) control. The MET approach is physical, rather than the mathematical approach favored by electrical engineering technology. Such a pedagogical method relies on laboratory equipment and experiments whereby the features of PID control may be properly demonstrated. As an example, the student observes how different PID settings affect the fan speed in the control of air flow through a duct. Through the support of an ILI grant from the National Science Foundation, the MET program was able to purchase six Air Process Control Trainers to be used with personal computers supplied by the MET department. These units are used to control air speed and temperature in forced air flow through an instrumented duct. This paper will describe the equipment, the experimental procedure utilized, and the results, with a summary of the benefits to the students.

This paper is concerned with the development of a fully dynamic automotive suspension model in Virtual Test Bed (VTB), a dynamic system simulation environment developed by the University of South Carolina Department of Electrical Engineering for modeling multi-technical dynamic systems. VTB is normally used to prototype large scale electrical systems, but as shown in this paper, it can also be used to accurately simulate dynamic mechanical devices. Mathematical equations governing vehicle dynamic motion were developed and converted into C++ code. This code was then converted into a VTB model using Microsoft C++. A model of a full car passive suspension system was developed in VTB around this model, in which all dimensions, spring and damper constants, and vehicle path can be changed easily, without recoding the model itself. The model was then compared to a previously validated model created in Matlab Simulink. The results of this comparison, as well as validation with experimental data from a quarter-car suspension system, showed that VTB is a valid platform for modeling dynamic mechanical systems, and could be used to model active vehicle suspension as well.
