Learning digital test and diagnostics via Internet
An environment targeted to e-learning is presented for teaching design and test of electronic systems. The environment consists of a set of Java applets, and of web based access to the hardware equipments, which can be used in the classroom, for learning at home, in laboratory research and training, or for carrying out testing of students during exams. The tools support university courses on digital electronics, computer hardware, testing and design for testability to learn by hands-on exercises how to design digital systems, how to make them testable, how to build self-testing systems, how to generate test patterns, how to analyze the quality of tests, and how to localize faults in hardware. The tasks chosen for hands-on training represent simultaneously research problems, which allow to fostering in students critical thinking, problem solving skills and creativity
Genuine lab experiences for students in resource constrained environments: The RealLab with integrated intelligent assessment.
Laboratory activities are indispensable for developing engineering skills. Computer Aided Learning (CAL) tools can be used to enhance laboratory learning in various ways, the latest approach being the virtual laboratory technique that emulates traditional laboratory processes. This new approach makes it possible to give students complete and genuine laboratory experiences in situations constrained by limited resources in the provision of laboratory facilities and infrastructure and/or where there is need for laboratory education, for large classes, with only one laboratory stand. This may especially be the case in countries in transition. Most existing virtual laboratories are not available for purchase. Where they are, they may not be cost friendly for resource constrained environments. Also, most do not integrate any form of assessment structure. In this paper, we present a very cost friendly virtual laboratory solution for genuine laboratory experiences in resource constrained environments, with integrated intelligent assessment
Designing experiments using digital fabrication in structural dynamics
In engineering, traditional approaches aimed at teaching concepts of dynamics to engineering students include the study of a dense yet sequential theoretical development of proofs and exercises. Structural dynamics are seldom taught experimentally in laboratories since these facilities should be provided with expensive equipment such as wave generators, data-acquisition systems, and heavily wired deployments with sensors. In this paper, the design of an experimental experience in the classroom based upon digital fabrication and modeling tools related to structural dynamics is presented. In particular, all experimental deployments are conceived with low-cost, open-source equipment. The hardware includes Arduino-based open-source electronics whereas the software is based upon object-oriented open-source codes for the development of physical simulations. The set of experiments and the physical simulations are reproducible and scalable in classroom-based environments.Peer ReviewedPostprint (author's final draft
Improving the Power Electronics Laboratory teaching/learning process: an interactive web tool
European Higher Education Area; Power Electronics Laboratory; educational methods
Resumen: The forthcoming European Higher Education Area implies an important change in the teaching/learning process: it is necessary to get students more involved as well as to promote their independence and active participation. To achieve this objective, the new teaching methodologies aimed at more effective and appropriate learning for professional practice involve the use of audiovisual, computer and multimedia tools on the part of lecturers. Therefore, a web tool, based on a content management system, has been developed for the teaching in Power Electronics Laboratory. Moreover, the use of these multimedia tools makes possible to promote the students independence. Finally, the use of this web tool results in a very significant increase in the motivation students.Universidad de MĂĄlaga. Campus de Excelencia Internacional AndalucĂa Tech
A course on digital electronics based on solving design-oriented exercises by means of a PBL strategy
Recently, new syllabuses are being implemented accordingly to the European Higher Education Area (EHEA) in Spain.
This paper describes the methodology and assessment strategy applied in the subject ââDigital Circuits and Systemsââ (CSD)
in the third semester course in the Telecommunications Engineering degree at the Castelldefels School of Telecommunications
and Aerospace Engineering (EETAC) of the Universitat Polite`cnica de Catalunya (UPC). The courseâs main learning
objective is that students be able to analyse and design simple combinational and sequential circuits by means of hardware
description languages for programmable devices and program applications using microcontrollers and C language.
Small groups of two or three students work in cooperation using PBL techniques to solve design-oriented assignments,
while instructors act more as mediators than lecturers in order to facilitate project development and knowledge acquisition.
The experience we describe corresponds to the spring term of 2011, a period in which this methodology was applied to 46
students.
This work compares statistically the influence of the studentsâ background on their academic performance in our subject.
A significant correlation has been detected between test marks and the final grade, based on continuous assessment.
Studentsâ opinions have been obtained by means of a survey at the end of the course. Although the high workload and
involvement, because this methodology requires constancy and commitment from the students, most of them have positive
opinions on the development of the subject, due to the fact that they realise that they have put into practice several
competences or cross-curricular skills, while acquiring the course content, and furthermore, most of them have passed the
course, even with higher grades than the ones from other subjects in the same semester.Peer ReviewedPostprint (published version
Electronics and control technology
Until recently, there was no requirement to learn electronics and control technology in the New Zealand school curriculum. Apart from isolated pockets of teaching based on the enthusiasm of individual teachers, there is very little direct learning of electronics in New Zealand primary or secondary schools. The learning of electronics is located in tertiary vocational training programmes. Thus, few school students learn about electronics and few school teachers have experience in teaching it.
Lack of experience with electronics (other than using its products) has contributed to a commonly held view of electronics as out of the control and intellectual grasp of the average person; the domain of the engineer, programmer and enthusiast with his or her special aptitude. This need not be true, but teachers' and parents' lack of experience with electronics is in danger of denying young learners access to the mainstream of modern technology
Advanced Testing Chain Supporting the Validation of Smart Grid Systems and Technologies
New testing and development procedures and methods are needed to address
topics like power system stability, operation and control in the context of
grid integration of rapidly developing smart grid technologies. In this
context, individual testing of units and components has to be reconsidered and
appropriate testing procedures and methods need to be described and
implemented. This paper addresses these needs by proposing a holistic and
enhanced testing methodology that integrates simulation/software- and
hardware-based testing infrastructure. This approach presents the advantage of
a testing environment, which is very close to f i eld testing, includes the
grid dynamic behavior feedback and is risks-free for the power system, for the
equipment under test and for the personnel executing the tests. Furthermore,
this paper gives an overview of successful implementation of the proposed
testing approach within different testing infrastructure available at the
premises of different research institutes in Europe.Comment: 2018 IEEE Workshop on Complexity in Engineering (COMPENG
A new Slow Control and Run Initialization Byte-wise Environment (SCRIBE) for the quality control of mass-produced CMS GEM detectors
The CMS collaboration aims at improving the muon trigger and tracking
performance at the HL-LHC by installing new Gas Electron Multiplier (GEM)
chambers in the endcaps of the CMS experiment. Construction and commissioning
of GEM chambers for the first muon endcap stations is ramping up in several
laboratories using common quality control protocols. The SCRIBE framework is a
scalable and cross-platform webbased application for the RD51 Scalable Readout
System (SRS) that controls data acquisition and analyzes data in near real
time. It has been developed mainly to simplify and standardize measurements of
the GEM chamber response uniformities with x-rays across all production sites.
SCRIBE works with zero suppression of raw SRS pulse height data. This has
increased acquisition rates to 5 kHz for a CMS GEM chamber with 3072 strips and
allows strip-by-strip response comparisons with a few hours of data taking.
SCRIBE also manages parallel data reconstruction to provide near real-time
feedback on the chamber response to the user. Preliminary results on the
response performance of the first mass-produced CMS GEM chambers commissioned
with SCRIBE are presented
