Abstract

CAD methods and purpose‐designed software packages are now widely used in engineering practice and it is important to introduce students of undergraduate courses to these in preparation for their future employment in this environment. In the areas of electronic circuit design and analysis this has already been done successfully using such packages as ORCAD and SPICE and a similar situation exists in simulation with MATLAB and ACSL, all of which are now used extensively in university courses. However, with a few notable exceptions, less progress has been made with finite element electromagnetics packages even though this subject area benefits greatly from the use of these. Experience shows that many students find such packages somewhat uninspiring and are only convinced of their value when they have seen them applied to problems involving real hardware. Accordingly, the approach described in this paper incorporates the use of a modern professional package into a suite of three laboratory experiments, so allowing comparisons to be made between computed, calculated and measured quantities. A further problem, that of the long time required to learn the operating system for such packages, which usually greatly exceeds the three hours or so generally allotted to such activities, is eased by providing pre‐compiled programme segments for the major procedures. By this means, while still proceeding through all the stages necessary in solving a real problem, students avoid the most time consuming and routine parts of these and so are able to progress quickly to a solution. This technique is described in some detail in a previous paper.

Abstract

Due to their high magnetizing field requirement, the emergence of rare‐earth based permanent magnets is creating onerous demands on the capacitor‐discharge systems which are used for their initial magnetization, a process which is aggravated by the fact that the transient current pulse induces eddy currents, which inhibit the penetration of the magnetizing field, and causes heating and stressing of the magnetizing fixture. The problems are compounded in multi‐pole and post‐assembly magnetization systems, particularly for fine pole‐pitch fields. However this paper concentrates on the pre‐magnetization of magnets in air‐cored solenoids, which, despite the difficulty in subsequently handling magnetized magnets, remains the most common requirement. It presents a methodology for the design of impulse magnetizing solenoids to produce the amplitude and time to peak of magnetizing field required for a specific generic type and aspect ratio of magnet to be magnetized, and describes a procedure for the subsequent analysis of the complete impulse magnetization system.

Abstract

Purpose

This paper aims to describe two themes of information and knowledge management in building corporate memory through curation in complex systems. The first theme describes the skillsets of new memory curators: curation; appraisal; strategist and manager. The second theme describes four concepts that support information management in complex systems: David Snowden’s just-in-time process; Polanyi’s personal knowing; Wenger’s transactive memory system; and David Snowden’s ASHEN database schema.

Design/methodology/approach

Academic journals and professional publications were analysed for educational requirements for information professionals in complex adaptive systems.

Findings

The skills described should be readily applied and useful in a complex adaptive system with the four concepts described. The four concepts displayed features indicating each separate concept could be aligned and integrated with the other concepts to create an information sharing model based on synergy between reasoning and computing.

Research limitations/implications

Research is needed into the capability and potential of folksonomies using recordkeeping metadata and archival appraisal to support peer production information and communication systems.

Originality/value

The author has not found any research that links archival appraisal, user-generated metadata tagging, folksonomies and transactive memory systems governance policy to support digital online, co-innovation peer production.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between housing finance institutional related variables and financial related variables of low-income earners in Bauchi Local Government Area, Bauchi, Nigeria.

Design/methodology/approach

In this study, quantitative research approach was adopted. Self-administered structured questionnaires were used to collect information from 500 primary school teachers in Bauchi Local Government Area, Bauchi, Nigeria. A correlation analysis was carried out to find the relationship between housing finance institutional contexts and finance contexts to low-income earners in the study area using SPSS Version 23 software.

Findings

The findings shows that the low-income earners were more concerned with the accessibility and affordability on housing ownership, and it also showed that performance and effectiveness of the housing finance institutions were of paramount importance to housing ownership for the low-income earners in the study area.

Practical implications

The finance institutions are the prime consumer of these research findings. The participants in the finance institutions are going to benefit from the low-income earners’ housing ownership development.

Originality/value

The paper also emphasized that the finance institutions should make the housing finance loan accessible and affordable to the low-income earners to meet their dream to sustainable housing ownership.

Abstract

SOME popular journals have, for some time now, been publishing a short list of books which are selling successfully. Books and Bookmen has a feature of the best‐selling titles from two or three bookshops in town and the provinces; Time and Tide publishes a list compiled with the assistance of the National Book League: Time in its “Time Listings” enumerates the top twenty best sellers (of America) and similar lists no doubt appear in other journals. The outstanding characteristic of these lists is the remarkably high quality of the books mentioned. Rare indeed is a title which would not deserve a place on the shelves on any public library. Most of the titles are, of course, new, although it is interesting to note how really outstanding titles retain a place on the lists for many weeks. Thus in the last “Time Listing”, Dr. Zhivago, Breakfast at Tiffany's, and Aku Aku among others, have all been published for some months.

Abstract

This paper is based on a personal journey of starting a long-term sociological research project in a conflict zone: the research was to be carried out in Israel and the Palestinian Territories. The question posed is: what sort of problems and concerns arise for researchers and ethnographers who work with traditionally marginal communities in violently divided societies? In an attempt to provide an answer, I focus here on such issues as: the social constructions of fears and dangers in what are perceived to be dangerous places; difficulties of access to traditionally underrepresented and marginal social groups; useful methodological and ethical precepts for doing research in risky environments; as well as the advantages of working with, rather than on communities. Moreover, I suggest that conducting research in politically and socially unstable contexts puts into stark relief the advantages of conducting participatory and collaborative research. Such approaches provide researchers with networks of trusted local protagonists, offer more in-depth insights into traditionally marginalized and frequently misrepresented social groups, whilst also generating knowledge that may facilitate beneficial social changes for local communities.
