Teaching behavioral modeling and simulation techniques for power electronics courses / Abramovitz, A. in IEEE transactions on education, Vol. 54 N° 4 (Novembre 2011) 

Public ISBD [article]  in IEEE transactions on education > Vol. 54 N° 4 (Novembre 2011) . - pp. 523 - 530 Titre : Teaching behavioral modeling and simulation techniques for power electronics courses Type de document : texte imprimé Auteurs : Abramovitz, A., Auteur Année de publication : 2013 Article en page(s) : pp. 523 - 530 Note générale : Education Langues : Anglais (eng) Mots-clés : Feedback  Feedback  circuits  Power  factor  Simulation  Switch-mode  power  conversion Résumé : This paper suggests a pedagogical approach to teaching the subject of behavioral modeling of switch-mode power electronics systems through simulation by general-purpose electronic circuit simulators. The methodology is oriented toward electrical engineering (EE) students at the undergraduate level, enrolled in courses such as “Power Electronics,” “Industrial Electronics,” or the like. The proposed approach is demonstrated by simulation example of a realistic active power factor corrector (APFC) system. The paper discusses the derivation of PSPICE/ORCAD-compatible behavioral models, their software implementation, and fast time domain, frequency domain, and stability analysis simulation techniques suitable for virtual study of complex nonlinear feedback systems. Some “tricks of the trade” are also suggested. The paper can be helpful to instructors of a “Virtual Power Electronics Laboratory” course wanting to conduct a software experiment on a PFC system.

The aims of this study were to explore the effectiveness of second-year undergraduate computing students in carrying out a systematic literature review and to identify the elements of the process that the students found most difficult. A multicase case study of students carrying out an assignment to perform a systematic literature review (SLR) was undertaken. Students worked in groups and were studying across a range of computing programs. Data was collected from three sources: student grades, the comments made by the teaching staff on the submitted reports, and a debriefing questionnaire. All of the groups successfully completed the assignment. Results on which parts of the process were the most difficult were mixed, although much of the evidence suggests that the students found the conduct phase more problematic than the planning phase. It can be concluded that undergraduates can do SLRs, but the task is clearly quite challenging and time-consuming. SLRs are well suited to being undertaken by groups.

Cybertech is not only a well-known robotic contest in Spain due to the Robotaurus bullfighting, but is also a whole academic activity spanning theory, laboratory practical lessons, seminars, tutoring, and a spectacular contest in which robots, developed by the students, compete. It is an open activity, for all students and grades, requiring knowledge of various subjects such as mechanics, microcontrollers, control, and electronics. The experience acquired has shown how this novel educational approach can boost the motivation of students, who in a real applied project effectively learn not only the particular subject matter, but also skills in teamwork, oral presentations, budget management, and so on. This is considered the flagship of innovation in education at UPM. This paper describes the evolution of Cybertech over the past 10 years, summarizes the educational experience, and provides some statistics and results as well as a perspective for future editions of the competition.

Education has not remained unaware of this trend, and several educational solutions based on cloud technologies are already in place, especially for software as a service cloud. However, an evaluation of the educational potential of infrastructure and platform clouds has not been explored yet. An evaluation of which type of cloud would be the most beneficial for students to learn, depending on the technical knowledge required for its usage, is missing. Here, the first systematic evaluation of different types of cloud technologies in an advanced course on network overlays with 84 students and four professors is presented. This evaluation tries to answer the question whether cloud technologies (and which specific type of cloud) can be useful in educational scenarios for computer science students by focusing students in the actual tasks at hand. This study demonstrates that platform clouds are valued by both students and professors to achieve the course objectives and that clouds offer a significant improvement over the previous situation in labs where much effort was devoted to setting up the software necessary for course activities. These results most strongly apply to courses in which students interact with resources that are non-self-contained (e.g., network nodes, databases, mechanical equipment, or the cloud itself), but could also apply to other science disciplines that involve programming or performing virtual experiments.

Step-by-step design of an FPGA-based digital compensator for DC/DC converters oriented to an introductory course / Zumel, P. in IEEE transactions on education, Vol. 54 N° 4 (Novembre 2011) 

Public ISBD [article]  in IEEE transactions on education > Vol. 54 N° 4 (Novembre 2011) . - pp. 599 - 609 Titre : Step-by-step design of an FPGA-based digital compensator for DC/DC converters oriented to an introductory course Type de document : texte imprimé Auteurs : Zumel, P., Auteur ; Fernandez, C., Auteur ; Sanz, M., Auteur Année de publication : 2013 Article en page(s) : pp. 599 - 609 Note générale : education Langues : Français (fre) Mots-clés : digital  control;  educational;  field-programmable  gate  array  (FPGA);  power  electronics Résumé : In this paper, a short introductory course to introduce field-programmable gate array (FPGA)-based digital control of dc/dc switching power converters is presented. Digital control based on specific hardware has been at the leading edge of low-medium power dc/dc switching converters in recent years. Besides industry's interest in this topic, from the educational point of view, digital control is a multidisciplinary subject that is very attractive to include in various programs of study. The course presented here covers the calculation and implementation procedure for a linear compensator based on an FPGA for a dc/dc converter.

Digital control based on specific hardware has been at the leading edge of low-medium power dc/dc switching converters in recent years. Besides industry's interest in this topic, from the educational point of view, digital control is a multidisciplinary subject that is very attractive to include in various programs of study. The course presented here covers the calculation and implementation procedure for a linear compensator based on an FPGA for a dc/dc converter. The approach taken is structured in a step-by-step design flow combining theoretical justifications, use of CAD tools, and lab experience. The course can be adapted to students' various backgrounds and time schedules. En ligne : http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5688206&sortType%3Das [...]

Trajectories of electrical engineering and computer engineering students by race and gender / Lord, Susan M. in IEEE transactions on education, Vol. 54 N° 4 (Novembre 2011)

Computer engineering (CpE) has a similar curriculum, but different demographics and student outcomes. Using a dataset from universities in the U.S. that includes over 70 000 students who majored in engineering, this paper describes the out comes for students matriculating in and migrating into EE and CpE so as to inform the decision making of faculty, department heads, and deans. Although men consistently outnumber women in EE and CpE, the rates of matriculation and six-year graduation vary by race and gender. EE is the most popular choice for Asian and Black students (males and females) at matriculation, but while Asians graduate at high rates, Blacks (particularly males) are not retained. Retention is higher in EE than in CpE despite the similarity of the curricula. Graduation rates are lower than expected for women of all races in CpE and for Hispanic women in EE. By the third semester, some students of all races and genders have left their matriculation major, but others have migrated in from other majors, compensating for some of this loss. CpE students are more likely than EE students to switch to another major. Trajectories of EE and CpE students are racialized and distinct. CpE loses more students and attracts fewer students than EE. These findings il lustrate the importance of disaggregating by engineering major as well as race and gender to improve recruitment and retention overall.

A cochlear implant signal processing lab / Bhatti, P. T. in IEEE transactions on education, Vol. 54 N° 4 (Novembre 2011) 

Public ISBD [article]  in IEEE transactions on education > Vol. 54 N° 4 (Novembre 2011) . - pp. 628 - 636 Titre : A cochlear implant signal processing lab : exploration of a problem-based learning exercise Type de document : texte imprimé Auteurs : Bhatti, P.

Centered in a real-world application, a cochlear implant, the exercise challenged students to demonstrate a working software-based signal processor. Partnering in groups of two or three, second-year electrical and computer engineering and biomedical engineering students used MATLAB graphical user interface programs, complemented with their own original MATLAB code, to design filters suitable for achieving a filter bank decomposition of an audio signal. Rather than using the envelope-detected output for direct electrical stimulation of auditory nerve fibers as in an implant, the students reconstructed the signal by modulating sinusoids to yield an acoustic simulation. To appreciate the impact of filter order on sound intelligibility, students were asked to reconstruct signals using 4-16 filter channels for both speech and music and to examine the results critically. The lab served as a substrate upon which to solidify fundamental signal processing concepts such as the distinction between time and frequency domains, constructing and interpreting spectrograms, sampling, spectral decomposition, filtering, and reconstruction. In the spirit of PBL, the students examined engineering tradeoffs and discussed implementations when they were asked to consider realizing a significantly higher channel count (128-channel) device. To determine how the laboratory exercise impacted student learning and comprehension, as well as the level of student engagement achieved with this compelling application, an anonymous online survey was administered at the end of the course. The survey outcomes, as well as the components of the lab, are discussed in the context of PBL pedagogy.

Unfortunately, little is known about how students learn the fundamental concepts in computing. To investigate student conceptions and misconceptions about digital logic concepts, the authors conducted a qualitative interview-based study. In the interviews, students verbalized their thinking while they solved digital logic problems. The interviews were analyzed to identify students' misconceptions. This paper presents five classes of students' misconceptions and methodological weaknesses concerning medium-scale integrated (MSI) circuits. These misconceptions were used to create a multiple-choice conceptual assessment, called a concept inventory, that is being used to test for the prevalence of the misconceptions discovered through the interviews. Although the misconceptions documented in the paper are primarily intended for the construction of the concept inventory, they can also point to potential ways to improve instruction.

As an in-class example, students in a solid-state electronics course used the Web site interface to make real-time transistor measurements. Recommendations are made on how to best integrate the interface into electronics classes based on the student assignment responses. The present interface is flexible and could be expanded to many other devices and instruments. The source code has been openly posted online.

Teaching discrete and programmable logic design techniques using a single laboratory board / Debiec, P. in IEEE transactions on education, Vol. 54 N° 4 (Novembre 2011)

From the pedagogical point of view, two problems arise in these laboratories. First, students have some difficulties in understanding the link between discrete and programmable design techniques. Second, using only a single PLD, students are not automatically forced to learn modular design skills, which is one of the required learning outcomes in electrical engineering (EE) curricula. To overcome these problems, an innovative laboratory is proposed in this paper. Each training board contains four complex PLDs (CPLDs) and peripherals. In the initial sessions, students implement designs in which CPLDs are programmed as standard SSI/MSI chips and interconnected to construct the target circuit. Then, an active learning technique is used: Students form groups of any size and can set themselves more complex problems and choose their design approach. The proposed laboratory was set up at the Technical University of Lodz, Lodz, Poland, and the first classes were given in the 2008-2009 academic year. The instructors' insights and design reports and feedback from students were gathered and analyzed. The results showed the effectiveness of the novel approach. Students were deeply involved in solving self-imposed problems. They learned “engineering imagination,” modular design, and teamwork skills. Some groups went far beyond the requirements set by the instructor. However, an additional conclusion is that the “standard” approach should not be completely eliminated.

It includes a set of features not found in other educational environments. This set of features is the result of an original combination of design requirements for T&D-Bench: that the framework should provide modeling capabilities similar to that of Architecture Description Languages (popular in embedded systems design), and that it should have the simulation capabilities found only in educational simulators. This paper highlights the main features and the latest achievements of the framework and of its didactic and research simulators. The results of a new didactic strategy, supported by the simulators, are presented and discussed. The design of a new architectural feature for embedded processors, using a research simulator, is introduced, and it is shown how to employ such a research work as an educational module to teach the complexities involved in embedded systems design.

This paper highlights the main features and the latest achievements of the framework and of its didactic and research simulators. The results of a new didactic strategy, supported by the simulators, are presented and discussed. The design of a new architectural feature for embedded processors, using a research simulator, is introduced, and it is shown how to employ such a research work as an educational module to teach the complexities involved in embedded systems design.
