On problem structuring in an electronic brainstorming (EBS) environment

Kunene, KN; Petkov, D (1998)

Research in the field of Group Decision Support Systems (GDSS) has focused on the following main issues: the Task (task complexity, clarity and rationality); the Individual (the profile of individual group members); the ...
A partitioning scheme for solving the exact K-item 0-1 knapsack problem

Kruger, MF; Hattingh, JM (1998)

Our investigation on the impact of partitioning the search space of the classical 0- 1 Knapsack Problem through the inclusion of equality constraints on the knapsack's cardinality, has given rise to the study we undertook ...
Effective information security monitoring using data logs

Krige, W; Von Solms, R (1998)

Log files or audit logs are files that record information about events that occur on a computer system at all times, that is if the log files are configured correctly. Most information security officers do not use this ...
Hardware system interfacing with Delphi 3 to achieve academic integration between the fields of computer systems and software engineering

Joubert, A; Jordaan, A (1998)

This paper explores the use of dive computer downloader units and Delphi 3 object-oriented structures to integrate the fields of Computer Systems and Software Engineering in the academic environment. Currently there is a ...
Quality considerations of real time access to multidimensional matrices

Janssen, F (1998)

This paper investigates the quality considerations of real time access to multidimensional matrices. Researchers have emphasised the relationship between multidimensional matrices and data warehousing in the past; the ...
Binary decision diagram representations of firewall and router access lists

Hazelhurst, S; Fatti, A; Henwood, A (1998)

The growth of network and internet communication creates several challenges for network design. Two important issues are security and performance. As the volume of communication increases together with the importance of ...
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 ...
Academic CS/IS infrastructure in South Africa; an exploratory stakeholder perspective

Bytheway, A; Hearne, G (1998)

In considering the requirements of an academic infrastructure that might support computer science and information systems education in South Africa, it is easy to be driven solely by the opportunities that innovative ...
Practical experience in running a virtual class to facilitate on-campus undergraduate teaching

Brown, S (1998)

This paper discusses the current use of an Internet Education Support Program (IESP). This software package uses Internet-based tools which allows the educator to use collaborative learning techniques in both face-to-face ...
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 ...
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 ...
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 ...
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 ...
On indexing in case based reasoning applied to pre-transportation decision making for hazardous waste handling

Wortmann, KL; Petkov, D; Senior, E (2000)

Case Based Reasoning is an Artificial Intelligence technique that utilises the concept of reasoning from a stored knowledge base reflecting prior experience. It offers a number of advantages, such as learning and validation ...
Object-oriented business modelling and re-engineering

Watzenboeck, M (2000)

Financial industry and manufacturing are the main customers in migrating existing applications into client server environments. This paper helps in identifying the candidates for migration and suggests a method for ...
The use of the Internet in an academic environment to commercially supply and support software products.

Braude, B; Walker, AJ (2000)

This paper explores the use of the Internet to supply and support software products within a quality management system. The Software Engineering Applications Laboratory (SEAL) at the University of the Witwatersrand is in ...
Early results of a comparative evaluation of ISO 9001 and ISO/IEC 15504 assessment methods applied to a software project.

Gee, C; Walker, AJ (2000)

This paper presents early results of a comparative study undertaken on a software project. The methods used for assessment included an ISO 9001 based audit checklist for software (SABS ARP042), and the emerging ISO/IEC ...
Beliefs of a resource-bounded agent

Viljoen, E (2000)

Logics of belief and knowledge are typically formulated in terms of modal languages. A possible world semantics is traditionally used for such languages but when a formula A is read as "The agent believes that A", the ...
Using a lattice to enhance adaptation guided retrieval in Example Based Machine Translation

Serutla, SL; Oosthuizen, GD (2000)

Ease of retrieval is of crucial importance in case based reasoning (CBR). In fact, the performance of a CBR system depends on how such a system is able to retrieve relevant cases from memory and adapts them to suit new ...
Ray guarding configurations of adjacent rectangles

Sanders, I; Lubinsky, D; Sears, M (2000)

Guarding and covering problems have great importance in Computational Geometry. In this paper the notion of a ray guard, a guard that can only 'see' along a single ray, is introduced. The problem of siting the fewest ...
