Student Laboratory

This paper discusses the problem of transferring knowledge to students of an undergraduate electrical measurement course, and also describes the design of a Web-based measurement laboratory and experimental setup of Web-based experiments at the Faculty of Electrical Engineering and Computing (FER) in Zagreb, Croatia. The suggested design offers the possibility of teaching or presenting high-precision experiments using expensive or sensitive equipment that is unavailable in sufficient quantities to serve large numbers of students.

Student laboratories have always played a key role in the engineering education at Stevens Institute of Technology (SIT). Recently, SIT has designed and implemented several innovative Web-based tools for engineering laboratory education and evaluated their learning effectiveness in pilot deployments in various engineering courses. These Web-based tools include both remotely operated experiments based on actual experimental devices as well as virtual experiments representing software simulations. These tools facilitate the development of learning environments, which - possibly in conjunction with traditional hands-on experiments - allow the expansion of the scope of the students' laboratory experience well beyond the confines of what would be feasible in the context of traditional laboratories. This becomes possible because of the scalability of resources that are shared through the Web and the flexibility of software simulations in varying the characteristic parameters of the experimental system under investigation. Further educational benefits of the proposed laboratory approach are that asynchronous learning modes are supported and discovery-based self-learning, of the students is promoted. This paper will present the details of the approach taken at SIT in integrating these Web-based tools into a comprehensive student laboratory experience. As an example for the implementation of such Web-based experiments, an Industrial-Emulator/Servo-Trainer System will be described, which is used at SIT in a junior-level course on mechanisms and machine dynamics.

With the rapid increase in the volume of e-commerce, the security of web-based transactions is of increasing concern. A widespread but dangerously incorrect belief among web users is that all security issues are taken care of when a website uses HTTPS (secure HTTP). While HTTPS does provide security, websites are often developed and deployed in ways that make them and their users vulnerable to hackers. In this article we explore some of these vulnerabilities. We first introduce the key ideas and then provide several experiential learning exercises so that readers can understand the challenges and possible solutions to them in a hands-on manner.

Student Inquiry

We describe our efforts at the University of Oregon to use Web-based Instructional Technology (IT) supplemented with interactive Java virtual experiments to change the standard pedagogy associated with large, introductory undergraduate classes in physics and astronomy. We begin by examining some of the problems associated with the standard pedagogy in these classes and how these problems motivated our development of networked courseware. Although we identify and describe five empirical positive outcomes associated with IT, we conclude that the use of HTML-based course material and assignments does not substantially alter the standard pedagogy as this medium alone is not conducive to interactive exercises. To build interactivity into our courseware, we have undertaken a vigorous effort of creating Java-based experiments which are grounded in physical reality and duplicate the kinds of experiments that are done in the physical lab. In so doing, we build experimentation into a curriculum for large lecture-based classes in which the standard pedagogy and resource constraints normally preclude lab sections. The main goal is to create a networked environment where the student can easily retrieve the notes and the demonstrations that were done in class as well as to engage in experiments that are designed to illustrate basic principles. In so doing, we hope to move to a more learner-centered environment which is driven by student inquiry. Five specific Java experiments are described here and each is accompanied by a snapshot of the experimental apparatus and controls. An appendix contains the relevant URLs of the experiments, courseware, and animation described herein.

Long Term Preservation

In this applied thesis project, a sample booklet of various expired silver gelatin papers is created. Specific information on the use of expired photographic papers by contemporary photographers is discussed as well as insights from collection caretakers (collection managers/archivists/conservators) on the possible implications that printing with expired silver gelatin papers may have for the long-term preservation of photographic works. The major contribution of this thesis is to create and gain a better understanding of tools that can be used in the characterisation and identification of expired silver gelatin papers. It is also to demonstrate that a tactile tool such as the sample booklet can assist in identifying various deterioration events. I feel that it is important to have a hands-on source that can be used independently or collectively with other sources such as web-based visual identification tools. The booklet will be useful as an educational tool for students, collection care takers, as well as professionals in the photographic field.

Standard Value

An electric motor that is used continuously will experience a decline in performance and even be damaged, maintenance and repair of electric motors must be done based on standards so that all existing specifications can be met and repairs deserve to be accepted. Where in this case motor repair is done by overhauling, where overhaul is a comprehensive repair or maintenance activity by repairing or replacing parts of electric motors that are damaged. Based on visual data and electrical measurements the decrease in the value of the polarization index (PI) of the induction motor is caused by dirty and moist winding conditions. Overhaul is done in 8 stages, namely; planning, dismantling, electrical measurement, mechanical measurement, electrical action, mechanical action, assembling and no load test running. After overhauling, the result shows that the value of the polarization index (PI) increased by 1.4 from 1.8 to 3.2, which is above the standard value set by IEEE 43.ABSTRAK:Suatu motor listrik yang digunakan terus menerus akan mengalami penurunan performa bahkan rusak, perawatan dan perbaikan motor listrik harus dilakukan berdasarkan standar supaya semua spesifikasi yang ada dapat terpenuhi dan perbaikan layak untuk diterima. Dimana pada kasus ini perbaikan motor diakukan dengan cara overhaul, dimana overhaul merupakan kegiatan perbaikan atau perawatan secara menyeluruh dengan cara memperbaiki atau mengganti bagian dari motor listrik yang mengalami kerusakan. Berdasarkan data visual dan pengukuran elektrik penurunan nilai polarization index (PI) motor induksi disebabkan oleh kondisi winding yang kotor dan lembab. Overhaul dilakukan dengan 8 tahapan, yaitu; planning, dismantling, pengukuran elektrik, pengukuran mekanik, tindakan elektrik, tindakan mekanik, assembling dan running test no load. Setelah overhaul didapatkan hasil bahwa nilai polarization index (PI) meningkat sebesar 1.4 dari sebelumnya 1.8 menjadi 3.2, berada diatas nilai standar yang ditetapkan oleh IEEE 43
