Effective use of a personal computer for small apparatus design andother engineering uses

The concern of computer-aided design (CAD) presented is primarily on the anatomy, rather than the technical content, of engineering programs to run personal computers. The author supplements his own ideas with suggestions by clients and borrows from user-friendly features found in current commercial personal computer software. For the design of small motors, or similar apparatus, the author strongly recommends an interactive approach due to the flexibility and training it offers. He emphasizes how valuable a word processor can be to an engineer for writing, editing, or debugging a Fortran program, or simply for writing a technical report or preparing a paper     

Computer integrated manufacturing: a case study in the cementindustry

Efforts by California Portland Cement (CPC) to decrease manufacturing costs and increase productivity throughout the cement division are discussed. One aspect of these efforts has involved the planning for and the application of computer integrated manufacturing (CIM) to provide managers at all levels with the tools and information they need to achieve these goals. The CIM effort has been directed at both corporate and plant functions and includes both manufacturing and support personnel. The breadth of the hardware installation has ranged from new distributed control systems to corporatewide data communications networks and individual personal computers and workstations. Applications software has ranged from typical motor control logic and direct digital control algorithms to distributed databases and expert systems. A generic CIM model is used to summarize work to date in three cement plants constructed or modernized over the last 25 years. Directions for the future are also highlighted. Special emphasis is placed on identifying the areas of highest return for CIM in the cement industry, and the practical and political pitfalls of implementing CIM in any manufacturing environment are discussed

Communications engineering: a new discipline for the 21st century

Communications engineering, a new undergraduate degree program, is being introduced in the Department of Systems and Computer Engineering at Carleton University in Ottawa, Canada. At a time when increased specialization is questionable, the case is made that communications engineering, i.e., telecommunications and computers, is such a broad and fundamental area that a distinct degree is an appropriate approach to meet the requirements for engineering in this area. The objectives of the new program and the role that its graduates will play are discussed. The curriculum proposed for the new degree is presented. In the new degree, which is derived from the telecommunications stream in electrical engineering and from computer systems engineering, students will receive a comprehensive education ranging from a one and one-half gear common core, to communications theory, design and practice, with consideration of economic, regulatory, and social issues with a strong background in real-time computer systems. Graduates will participate in the engineering of a variety of private and public telecommunications systems, and be at home in many related areas of information technology and signal processing     

A new approach to interactive tutorial software for engineeringeducation

The experimental tutorial software described in this paper is designed specifically for engineering education at the university level, and it is significantly different in purpose and structure from other educational software. Its goal is to help students understand, visualize, and connect basic concepts. It is not a design tool or a wealth of hyperlinked text or an infinite source of drill problems. It is intended to be a dynamic and flexible resource for instructors as well as students and to be used by groups as well as individuals. It takes advantage of currently available high-resolution graphics capability to go beyond what can reasonably be expected of textbooks or computer systems with small low-resolution displays. Since the software is written as an X Windows Motif application, it achieves a wide degree of platform independence for workstations and PCs. In addition, the tutorial set can be distributed without license fees or additional software acquisition costs for the user

An integrated environment for modeling, simulation, digital signalprocessing, and control

An integrated laboratory for system modeling, simulation, real-time digital signal processing, and control is being developed at Bucknell University for undergraduate electrical engineering education. The laboratory bridges the gap between software simulation and testing of actual systems through a common visual programming interface. Students can explore the iterative process of developing a model and then refining the model until computer simulation results agree with experimental measurements. A liquid level control system is presented to illustrate the features of the laboratory environment. The key components of the laboratory are networked digital signal processing (DSP) hardware units and a simulation software package. The simulation software runs on workstations, and all of the laboratory equipment (including the DSP hardware) is connected to the Internet

An Energy Conversion Laboratory Using Industrial-Grade Equipment

Laboratory experiences are an important component of the education of engineering students. Rotating machinery laboratories assist with the visualization of the three-dimensional and rotating equipment. Contemporary use of rotating machines in industry often includes adjustable speed drives and digital controllers. Additionally, instrumentation is used to feedback electrical and mechanical variables to the drives and controls. Using an equipment grant from an industrial automation manufacturer, cost-effective laboratory workstations have been developed. Industrial-grade equipment is not designed for student experimentation but was adapted for this use. The workstations described in this paper incorporate modern power electronic-based drives and motors, electrical and mechanical sensors, and a computer-based control system with data acquisition. The advantages of these workstations include cost-effectiveness and the use of actual industrial devices that students might encounter in industry. Additionally, the workstations can be accessed by remote users, enabling off-campus students to also perform experiments on the workstations. The paper includes details of the workstation and its components, the data acquisition and control system, and sample experimental results.     

Educational cellular radio network planning software tool

In this paper, an educational software tool (CELLPLAN) is presented. This tool is used to illustrate to telecommunications engineering students the different steps typically followed in the planning of cellular radio networks. The software tool described in this paper simulates the procedures and algorithms implemented in professional planning tools in a simplified way. The major difference being that no actual terrain information (Digital Terrain Model) is used in the simulations but rather a “generic” terrain configuration is assumed. The availability of this simulation tool in the classroom gives fifth-year telecommunications engineering students the opportunity to tackle realistic cellular network design cases as if they were in a real engineering office     

VICA-A SYSTEM FOR SINGLE-PHASE MOTOR DESIGN BY PERSONAL COMPUTER: AN APPROACH THAT BROADENS DESIGN SKILL AND ENCOURAGES CREATIVITY

Abstract

Spectacular recent developments in personal computers caused the author, who has been involved in computer-aided design of induction motors for over 25 years, to investigate if and how a pc could be used to design single-phase motors. In putting such a mainframe computer program on his own personal computer, the author found first, that the program had to be restructured, and then that it took more than twice as much memory as it did on the mainframe computer. Single-phase programs, described in this article, are now starting to be used in a number of locations, on personal and on mainframe computers. The author believes that there will be a growing use of personal computers in the future for this, and for other engineering applications.     

A flexible graphical user interface for embedding heterogeneousneural network simulators

A graphical user interface (GUI) for heterogeneous neural network simulators proposed in this article is intended to be of use both for the novice and for the experienced neural network user. For the novice, it provides an easy-to-use neural network simulation package that insulates the user from the requirements of knowing the simulator implementation details or the configuration file syntax. For the experienced neural network professional it provides an interface that is easily extensible to include any additional neural network simulator in its binary form. To satisfy both academic and personal computer environments, the GUI has been developed by using the free TCL/TK software package, available on workstations running Unix and on PCs running the free Linux operating system. Although the GUI and the embedded simulators have been successfully tested both in neural network research and training programs, a more extensive testing in undergraduate and graduate level classes is in progress     

Personal computers in electrical and computer engineering:education survey

The results are presented of a survey conducted to determine the impact of the personal computer on current electrical and computer engineering programs. A total of 82 schools responded to the questionnaire. The data obtained from the responses indicate that a large number of personal computers are available for students to use, but that their application in engineering programs is considerably less than might be expected. Some suggestions are made for ways in which this situation might be improved     

Experiences with a personal computer network in electricalengineering education

At the ESAT (Electronics, Systems, Automation, Technology) laboratory of the Katholieke Universiteit Leuven in Belgium extensive efforts have been made on the implementation of exercise sessions on a PC network. Since 1986, 13 different exercise sessions of eight different courses take place on the network for 300 students in the last three years of electrical engineering. The courses cover several aspects of electrical engineering education: linear and nonlinear systems, switching and control theory, electronic measurements, digital data transmission, etc. All the exercise sessions are menu driven and have the same pattern so that the students do not need a background in computers or software. The use of a computer permits the student to spend more time on testing and analyzing several solution methods, conditions, restrictions and properties of certain techniques, etc. instead of wasting time on repetitive calculations. An example that demonstrates the advantages of using a personal computer to solve an exercise is given, followed by the purposes of the network. The configuration of the network, its hardware, and software are presented. The contents of each session are briefly discussed and one session is explained in more detail. Student evaluations are described that indicate the success of the networked exercise sessions     

The computer revolution

The history of computers is briefly reviewed. The development of personal computers (PCs) is then summarized. The microprocessor itself, random-access storage, mass storage, and the evolution of PC software and computing performance are considered. The potential for further improvement is examined     

Teaching electric machinery and associated electromagnetic fields-acase for the benefits of academic computing

Three broad categories of benefits resulting from use of and access to personal computers (PCs) and workstations (WSs) in teaching electric machines and drives, including all the electromagnetic field aspects associated with such electromechanical energy conversion devices are described. The first category concerns benefits from using computer graphics in computational electromagnetics. The second category involves quantification of electric machinery parameters and performance characteristics from computational electromagnetics. The third category concerns benefits from using computer simulation to study power-electronically-controlled electric drives, using time-domain models in which all significant effects of both time and space harmonics are retained. The material discussed is taught at Clarkson University at the senior undergraduate and first-year graduate levels     

Introducing computer structure by machine simulation

A simple computer simulator used to introduce freshmen engineering students to machine structure through assembly programmable is described. A four-week course module is described, suited to the IEEE curriculum recommendations. It is built around a simulator called Simian and an accompanying assembler keyed to the IEEE-694 standard. Simian simulates a byte-addressable 32-bit machine, continuously displaying register contents and selected portions of memory. Version of Simian exist for both Unix and MS-DOS, permitting students to use it both in the laboratory and on personal computers. Learning time for Simian itself, a critical parameters in simulators designed for teaching, is 1-2 hours for students with little prior computer experience
