Watch out, Tiger Woods![golf playing robot]

This article describes the development of an autonomous robotic system for playing mini-golf. The system was designed and built to serve as a demonstration of robotic application for engineering students. The system was built using a Yasakawa robot fitted with two arms. The software was developed to control the machine using the C++ language. Standard C++ libraries were used in addition to communication libraries provided by the Yasakawa Corporation. The current configuration works with Microsoft Windows NT and an Ethernet environment. This article describes the hardware and software design aspects of this machine.     

Project-based teaching software for structural design

The paper describes the way in which CAL software has been developed and used to assist in the teaching of structural design, in the context of final-year project work. The software has been written specifically to enable students to design steel portal frames, which are the most common structures used in industrial construction. It is highly interactive, makes considerable use of graphics and “help” facilities, but avoids leading the student automatically towards acceptable solutions. It was developed as part of a British Steel Corporation initiative for teaching of structural steelwork at undergraduate level and runs on a BBC microcomputer. The software is used in the context of a whole-day design exercise in which students work in small groups to produce alternative designs for an industrial shed. Different configurations can be compared and the effect of amendments investigated, which has never previously been feasible. Its use during the last three years has shown distinct advantages over existing design teaching methods, particularly in the conceptual aspects.

The lean gap: A review of lean approaches to large-scale software systems development

Lean approaches to product development (LPD) have had a strong influence on many industries and in recent years there have been many proponents for lean in software development as it can support the increasing industry need of scaling agile software development. With it's roots in industrial manufacturing and, later, industrial product development, it would seem natural that LPD would adapt well to large-scale development projects of increasingly software-intensive products, such as in the automotive industry. However, it is not clear what kind of experience and results have been reported on the actual use of lean principles and practices in software development for such large-scale industrial contexts. This was the motivation for this study as the context was an ongoing industry process improvement project at Volvo Car Corporation and Volvo Truck Corporation.

Software piracy among computing students: a Bruneian scenario

Software piracy committed by university students in the western world has been published widely in various computer literature. Little is reported however about why and what proportion of students, particularly computing students, in a South East Asian Country like Brunei Darussalam, use pirated software. A survey was thus conducted among the computing students of all the higher educational institutions in Brunei Darussalam. A normative model was also developed that brought together eight factors related to student demography, nature of educational institutions and copyright laws. This model was empirically tested using 91 responses received from the survey. Several interesting findings emerged. Firstly, nearly two-thirds of the students admitted to having used pirated software. Secondly, entertainment was the prominent reason for using pirated software. Thirdly, gender, computer experience and ownership of a personal computer, were found to affect students' use of pirated software. Fourthly, even those students who supported the introduction of copyright laws committed software piracy. The implications of these findings are discussed, and are compared with some related studies. Finally, limitations of the study are mentioned, and areas of further research are identified.

A pragmatic proposal for the improvement of program modularity and reliability

Thedomain concept-discussed in an earlier paper-is essentially no more than a generalization of the classical operating system monitor. It is argued that domain machines may be put into immediate practical use in order to further and enhance the modularity and reliability of general software. By providing an arbitrary number of monitor-like protective structures, the monitor's proven advantages of database protection and controlled procedure entry points may be applied-within the domain machine's run-time environment-at a much finer level of modular resolution. Examples are given to demonstrate the domain architecture's ability to interdict (and intercept!) various software error conditions. It is suggested that in view of present economic realities (increasingly expensive software, ever less expensive hardware), the potential improvement of software quality through use of a more sophisticated hardware base may be worth considering by the industry.This paper is a statement of the author's personal position, which is not necessarily that of Digital Equipment Corporation.

Implementing concurrent scheme for the Mayfly distributed parallel processing system

This paper discusses a parallel Lisp system developed for a distributed memory, parallel processor, the Mayfly. The language has been adapted to the problems of distributed data by providing a tight coupling of control and data, including mechanisms for mutual exclusion and data sharing. The language was primarily designed to execute on the Mayfly, but also runs on networked workstations. Initially, we show the relevant parts of the language as seen by the user. Then we concentrate on the system Lisp level implementation of these constructs with particular attention toagents, a mechanism for limiting the cost of remote operations. Briefly mentioned are the low-level kernel hardware and software support of the system Lisp primitives.Work Supported in part by the Hewlett-Packard Corporation.

Learning spreadsheets: human instruction vs. computer-based instruction

Abstract

The increasing need to instruct students in the use of personal computer software, especially electronic spreadsheets, is placing greater demands on the already full university curriculum. A potential help in meeting these demands is the readily available computer-based software tutorials. In order to explore the feasibility of computer-based instruction as an alternative to human instruction, this research compares two modes of instruction, computer-based and human. An experiment was conducted with groups of business student subjects. The research results indicate no difference in students‘ attitude towards computer-based instruction and human instruction of spreadsheets. Students’ short-term recall of the software syntax being taught is as strong with computer-based instruction as with human instruction. These results were not affected by the level of personal computer experience that students had prior to the experiment. However, the ability to comprehend and immediately apply the software to a task is greater with human instruction than with computer-aided instruction. This advantage holds true for students instructed by experienced and inexperienced instructors.     

Equity perceptions as a deterrent to software piracy behavior

Software piracy is a problem for the software industry. An estimated world-wide piracy rate of 35%, representing approximately a $31 billion dollar loss in 2004 was reported by the second annual Business Software Alliance (BSA) and International Data Corporation (IDC) piracy study. This high rate shows piracy to be a significant global problem. Both BSA and the Software and Information Industry Association consider the impact of piracy to be a critical issue and have established web links to allow anonymous reporting of software piracy. Deterrents have been welcomed by software producers and others. Equity theory offers a possible explanation of software piracy behavior but no models have been shown to link equity constructs as having a direct influence on software piracy. We investigated the use of equity theory (fairness) as a deterrent to software piracy. Our results identified equity components that significantly influenced equity in the context of software piracy and further indicated that equity significantly influenced software piracy.
