This column provides background science information for elementary teachers. When the author was young he used to think that the ideal design for a concert hall would contain walls that were composed of sound-absorbing material, like foam or egg cartons or such. He noticed, though, that this was not the case. Most concert halls contain curtains…

While highly cohesive groups are potentially advantageous they are also often correlated with the emergence of knowledge and information silos based around those same functional or occupational clusters. Consequently, an essential challenge for engineering organisations wishing to overcome informational silos is to implement mechanisms that…

ADCs (analog-to-digital converters), especially Pipeline and Sigma-Delta converters, are designed using complex architectures in order to increase their sampling rate and/or resolution. Consequently, the learning of ADC devices also encompasses complex concepts such as multistage synchronization, latency, oversampling, modulation, noise shaping,…

The semiconductor industry is lacking qualified integrated circuit (IC) test engineers to serve in the field of mixed-signal electronics. The absence of mixed-signal IC test education at the collegiate level is cited as one of the main sources for this problem. In response to this situation, the Department of Electrical and Computer Engineering at…

An overview of a course on modeling and simulation offered at the Nanotechnology Engineering undergraduate program at the University of Waterloo. The motivation for having this course in the undergraduate nanotechnology curriculum, the course structure, and its learning objectives are discussed. Further, one of the computational laboratories…

In this article, a course on high-frequency wireless communications systems is presented. With the 145-MHz baseband subsystem available from a prerequisite course, the present course emphasizes the design and implementation of the 2.45-GHz front-end subsystem as well as system integration issues. In this curriculum, the 2.45-GHz front-end…

The current generation of students coming into food science and engineering programs is very visually oriented from their early experiences. To increase their interest in learning, new and visually appealing teaching materials need to be developed. Two diverse groups of students may be identified based on their math skills. Food science students…

Presents a technique for the numerical inversion of Laplace Transforms and several examples employing this technique. Limitations of the method in terms of available computer word length and the effects of these limitations on approximate inverse functions are also discussed. (JN)

This paper reports on a novel approach taken by the author to the teaching of an Internet programming course targeted at final year diploma and second year degree students. The uniqueness of engineers and their identity is discussed, as is the self-constructed world and ways of knowing in which humankind operates. The novel approach to teaching a…

Discusses development of an analog simulation program for microcomputers similar to those available on mainframe computers. The program is interactive, more user-friendly than batch mode mainframe simulators in use, and has user help, error detection, and medium resolution graphics for presentation of system responses. (JN)

Describes an inexpensive, simple, microprocessor-based instrument which quickly and accurately measures and displays the indicated power and the pressure-volume indicator diagram of a reciprocating compressor or internal combustion engine. Hardware requirements, software considerations, and the instrument's educational value are discussed. (JN)

A computer program for office layout design written for an Apple computer is discussed. Through its application, the user is freed from the tedious tasks of template manipulation and manual drawing and can therefore concentrate on the creative part of the design process. (Author/JN)

A Commodore-64 microcomputer was used to develop a system which is useful for a variety of teaching laboratory and real time control applications. Hardware and software requirements and examples of experimental work with the system are provided. (JN)

Describes a system (Apple II microcomputer interfaced to flexible, custom-designed digital hardware) which can provide: (1) Fast Fourier Transform (FFT) computation on real-time data with a video display of spectrum; (2) frequency synthesis experiments using the inverse FFT; and (3) real-time digital filtering experiments. (JN)

Presents algorithms for the simulation and motion display of the three basic kinematic devices: (1) four bar linkages; (2) the slider crank; and (3) the inverted slider crank mechanisms. The algorithms were implemented on a Commodore-VIC 20 microcomputer system with 6500 bytes of available memory. (Author/JN)
