Development of multimedia modules and courses for engineering education present a significant opportunity to modernize curricula and improve the effectiveness of teaching and learning. In this article we review the various hardware and software components required to develop multimedia lessons and discuss the role of each component in the structure of a multimedia module. Examples of multimedia lessons developed for CD-ROM distribution by the Center for Multimedia Education and Technology (CAEME) at the University of Utah are described. These include multimedia lessons in electromagnetics, the Calculus Castle, and the Physics Museum. It is shown that although extensive resources and expertise are often needed to develop these modules, development software and associated technologies are readily available and educators are encouraged to take advantage of these opportunities to reform, restructure, and improve engineering education.

This paper details the use of a circuit-based EM modelling technique combined with a harmonic balance simulator used to model the radiation from the microstrip bodies comprising an active antenna circuit. The modelling approach adopted for the planar bodies in the circuit will be shown to allow the use of concurrent algorithms in order to reduce overall computational time.

Teaching iterative and collaborative design: Lessons and directions 7th

7th Conference on Software engineering Education, SEI CSEE 1994

We describe the motivation for an ongoing series of experiments to enhance a team-based object-oriented software engineering course with a collaborative design tool. The course, which is taught in a single semester to senior undergraduates has achieved success in several dimensions, in particular in its application of object-oriented methods for analysis and design to the associated course project. We have recently started to increase the realism of the course by involving the students increasingly in iterative development, in particular on the system design level. We analyze some of the problems emerging from this decision and identify the key issues that must be addressed to allow for iteration in a single project course. A specific prototype information modeling environment supporting collaborative design is described and its applicability in the classroom is illustrated based on actual material from a recent version of the course. © Springer-Verlag Berlin Heidelberg 1994.

This paper describes the concurrent design of a wearable computer, called the Navigator, developed and built at Carnegie Mellon University in a multidesigner, multidomain environment. The design effort for the Navigator involved nineteen designers, representing the electronics, mechanical, industrial, software and human-computer interaction disciplines. The evolution of the multidisciplinary design is described, with particular emphasis placed upon the role of the thermal design group in the overall design process. Furthermore, the particular challenges associated with the concurrent thermal management of wearable computer systems are outlined.< >

IEEE Region 10 International Conference TENCON

作者： Tan Chong Hee G.R. Hellestrand VLSI Circuit Design and Test Department Institute of Microelectronics Singapore VLSI and Systems Technology Laboratory School of Computer Science and Engineering University of New South Wales Kensington NSW Australia

Presents a novel framework for the management of VLSI design processes. The framework allows the realisation of design process systems with capabilities that can match the problems to be solved. A framework called Colossus has been developed. It enables the VLSI design process space to be mapped onto distributed design domains, and it supports the necessary mechanisms for integrating the distributed capabilities of these domains to form design process systems. The systems realised are found to be flexible, in that their capabilities can be configured through design domain reorganisation and instantiation. Results obtained from a simplified layout generation system are presented to demonstrate the reconfiguration of system capabilities. In addition, the status of the framework and the systems implemented based on it are reported. It is believed that the framework can be used for the realisation of design process systems implemented across multiple hardware platforms and for the integration of multiple design process knowledge bases.< >

The application of multigrid techniques to the computation of the static solutions of electromagnetic field problems governed by Laplace's equation is described. This technique is compared with the conventional successive over-relaxation (SOR) method for solving finite difference problems. In contrast to SOR, the number of iterations of multigrid needed to achieve convergence is largely independent of the grid size. It is shown that the relative performance of multigrid is excellent on large grids where the number of iterations of SOR needed to achieve convergence becomes prohibitively large. The technique is illustrated by applying a parallel implementation of multigrid to find a quasistatic solution of a boxed microstrip problem.

NAVAL ENGINEERS JOURNAL 1993年第6期105卷 53-58页

作者： KIRKSHARIAN, A The Author:is currently managing the development of computer-aided design and manufacturing systems through the RAMP R&D project of the Naval Supply Systems Command Washington D.C. He acquired his BS degree in mechanical engineering in 1978 from the George R. Brown School of Engineering at Rice University and his MS degree in mechanical engineering in 1987 from Texas A&M University. An author of a number of articles in computer-aided manufacturing Mr. Kirksharian is a member of the Society of Manufacturing Engineers and the American Society of Naval Engineers.

This paper describes the development of a system to capture and provide computer-aided acquisition and logistics support (CALS) compliant product data of printed wiring assemblies. The Navy's Rapid Acquisition of Manufactured Parts (RAMP) Program has fostered the demonstration and use of product data standards which include EDIF, IPC-350, IGES, and CCITT Group 4 Raster. A comprehensive approach is outlined for the design and manufacturing use of electronic product data. This approach lays the foundation for the unified product data modeling efforts espoused for PDES/STEP. In conjunction with this outline, the development of a computer-aided design (CAD) system is described for the practical capture of existing technical data. A computer-aided engineering (CAE) capability exists to enhance or augment inadequate existing data.

A major limitation of the transmission-line matrix (TLM) method used to solve Maxwell's equations is the long computation time required. The TLM scattering calculations involved can, however, be viewed as parallel in nature. This paper describes an effort to reduce computational time by using an SIMD, DAP multiprocessor computer employed to solve a two-dimensional TLM electromagnetic field formulation. A parallel algorithm based on the TLM scattering algorithm is designed and implemented using FORTRAN-PLUS Enhanced on an AMT DAP 510 machine. Here the connectivity of the DAP is exploited to simulate the intrinsic scattering behaviour on which the TLM algorithm relies. The results show that parallel processing on an SIMD machine such as the DAP is advantageous, especially for higher-order mesh sizes.
