Design patterns for user interfaces

Warren, PR Viljoen, M (1998)

This work reports on 23 third year student' s projects in which the user interfaces (UI) were found wanting. We show in which ways we regard the UI to be in error. However, an examination of the available literature on UI ...
Non-orthogonal ray guarding

Sanders, I (1998)

In an earlier paper the notion of a ray guard --'- a guard that can only see along a single ray, was introduced. The ray guarding problem is in siting the fewest possible such guards so that they guard all adjacencies ...
Error analysis in selected medical devices and information systems

Randiki, E (1998)

The purpose of this paper is to identify and analyse error in selected medical devices: the Datex cardiocap and the capnomac Ultima II. These are both anaesthetic machines used to monitor patients in theatre. A secondary ...
Quality aspects of the development of a rule-based architecture

Chalmers, C (1998)

This paper provides an insight into how the various quality requirements defined for a specific tool are met in its development cycle. Focus is on a specific subset of the rule-based architecture project, which covers the ...
A case for reuse technology as a CS/IS training infrastructure

Adigun, MO (1998)

The advent of faster computing hardware and sophisticated software tools has not brought with it the much expected panacea for the so-called software crisis, rather we are now facing a software dilemma. Otherwise we should ...
One way to make better decisions related to IT outsourcing

Petkov, D Petkova, O (1998)

The subject of IT outsourcing has received a growing attention recently both by practitioners and researchers. There are a number of critical decisions to be made by a company embarking on outsourcing. These include a ...
Experience with Java in an advanced operating systems module

Roussev, B (1998)

The Advanced Operating Systems (AOS) module is one of the courses offered by the Computer Science Department in its honours program. The module aims are twofold: to enhance students' knowledge in single processor operating ...
A pluralist systemic framework for the evaluation of factors affecting software development productivity

Petkova, O Roode, JD (1998)

pAst software development productivity research has taken two main directions: in the first, research has concentrated on determining the factors which have a significant effect on productivity; and in the second, the ...
Handling diversity in information systems and computer science students: a social constructivist perspective

Thomas, T (1998)

This paper describes the social constructivist theory of learning and how it can be applied to handle the problems of diversity in Information Systems and Computer Science classes. Examples are given on methods that can ...
Electronic lectures for the mathematical subjects in computer science

Velinov, Y (1998)

In this paper we share our experience in the design of electronic lectures for theoretical subjects. The basis for our discussion are experiments for designing electronic lectures in Set Theory using the potential of ...
A 6-dimensional security classification for information

Smuts, W (1998)

Most existing information security classification schemes use a 1-dimensional scale such as [top secret, secret, employee confidential, company confidential, restricted]. These classification schemes do not differentiate ...
Response surface analysis as a technique for the visualization of linear models and data

Terblanche, F Hattingh, G (1998)

Response surface analysis aims of exploring the behavior of a response function in some region. Some authors (see e.g. [BRU] and [DEV]), have used this approach to get "better" interpretations of the behavior of linear ...
Academic institution and software vendor partnership

Van Niekerk, C (1998)

This talk will cover the following areas of importance to this problem: • Problems that Academic Institutions are facing today. • How Computer Associates want to get involved. • Overview of the Technology we are ...
Characteristics of high-performing information systems project managers and project teams

Smith, DC (1998)

Projects, and their success, are vital if organisations are to produce new products and services. The key players in IS projects are the project manager and the project team. This paper discussed ongoing research of two ...
Critical success factors for implementation of decision support systems

Averweg, UR Erwin, GJ (1998)

Decision Support Systems (DSS) are used to support decision-making for a non-structured management problem. DSS utilises data, provides an effective user interface and allows for the decision maker's insights to be ...
Partial edge visibility in linear time

Bilbrough, J Sanders, I (1998)

This research addresses the problem of partial edge visibility. This problem stems from work done in the ray guarding of configurations of adjacent rectangles [7]. In ray guarding these configurations it is necessary to ...
Refuting conjectures in first-order theories

De Waal, DA Hattingh, GN (1998)

Given some first-order theory, a formula (also called a conjecture) may or may not be a theorem of some theory. A theorem prover attempting to prove that the given formula is a theorem may terminate, proving that the formula ...
exA security interpretation of the workflow reference model

Botha, RA Eloff, JHP (1998)

This paper is intended as an opinion paper regarding information security concerns in the Workflow Reference Model (WfRM) as defined by the Workflow Management Coalition (WfMC). After an introduction into the workflow ...
Activities of IFIP WG 11.2 (Computer Security Education) & IT related ethics education in Southern Africa

Drevin, L (1998)

l. Activities and purpose of WG 11.8 WG 11.8 is one of the workgroups of TCl 1. WG 11.8 came together on 2 September 1998 on a boat between Vienna and Budapest as part of the IFIP World Computer Congress (WCC '98) where ...
A framework for information systems and national development research

Licker, PS (1998)

This paper develops a multidimensional framework to look at the role that information systems can play in the field of National Development. While there are already several frameworks, these are aimed at the employment ...
