Modular neural networks subroutines for knowledge extraction

Vahed, A; Cloete, I (1996)

Current research in modular neural networks (MNNs) have essentially two aims; to model systematic methods for constructing neural networks of high complexity and secondly, to provide building blocks for hybrid symbolic- ...
The feasibility problem in the simplex algorithm

Scott, TG; Hattingh, JM; Steyn, T (1996)

The simplex method is one way of solving a linear programming problem (LP-problem). The simplex method needs a basic feasible solution to start the solution process. This requires an available non-singular basis. Normally ...
A methodology for integrating legacy systems with the client/server environment

Redelinghuys, M; Steenkamp, AL (1996)

The research is conducted in the area of software methodologies with the emphasis on the integration of legacy systems with client/server environments. The investigation starts with identifying the characteristics of legacy ...
Protocol performance using image protocols

Kritzinger, PS (1987)

Performance analyses of data communication systems do not always rely on a detailed analysis of the underlying protocols. Those analyses which do, usually rely on an analysis of the protocol state transition graph. These ...
On total systems intervention as a systemic framework for the organisation of the model base of a decision support systems generator

Petkov, D; Mihova-Petkova, O (1996)

Decision Support Systems(DSS) have been dealing so far predominantly with semistructured problems for which existed well established Operations Research techniques. Most of them were originally oriented towards supporting ...
A technology reference model for client/server software development

Nienaber, RC (1996)

In today's highly competitive global economy, well-structured information resources, representing enterprise-wide information, are essential to the survival of an organization. The user needs an integrated view of the ...
Information systems outsourcing and organisational structure

Hart, ML; Vavatzanidis, K (1996)

A decision of increasing importance to many organisations is whether to use internal or outside resources, assistance and expertise to address information technology and information systems requirements. This decision may ...
Low-cost medical records system: a model

Diani, OA; Seipone, T (1996)

A low-cost microcomputer-based online system has been developed for the basic In-patient Medical Records functions of a General Hospital. Its basic functions are: to access patient data, register and admit a patient, enter ...
The practical application of a new class of 2D non-linear smoothers for digital image processing.

Cloete, E (1996)

Modern applications in computer graphics and telecommunications command high performance filtering and smoothing corrections to be implemented in real-time. The recent development of a new class of non-linear smoothers for ...
The role of IT in Business Process Reengineering

Blewett, CN; Cansfield, J; Gibson, L (1996)

South African organisations are facing increasing demands stemming from growing competition, fast changing technologies and global trends and pressures. The methods and management structures enabled these organisations to ...
A data structure for exchanging geographical information

Cooper, AK (1987)

Geographical information consists of non-spatial information (alphanumeric) and spatial information (vector and raster), the relationships between the non-spatial information and the spatial information, as well as the ...
Expert systems for management control: a multi-expert architecture

Ram, V (South African Computer Society (SAICSIT), 1991)

The use of Expert Systems technology in management decision making domains is increasing rapidly as business environments worldwide grow more turbulent and as the cost of development tools decrease. Research effort in ...
The FRD Special programme on collaborative software research and development. Draft call for proposals

Krzesinski, T (South African Computer Society (SAICSIT), 1994)

The foundation for Research Development (FRD) is evaluating the need for a new Special Programme in Computer Science. An initial meeting was held in August 1993 at the FRD to discuss the new programme. A Steering Committee ...
Developing soft skills in computer students

Schroder, C; Thomas, T (2000)

Today software developers are required to work closely with users when defining, developing and implementing systems. Interaction between software developers and users can influence the success or failure of the system ...
Modelling the algebra of weakest preconditions

Brink, C; Rewitzky, I (1991)

Dijkstra's weakest precondition semantics, as presented in textbook form by Gries, may be viewed as an equational algebra. The problem then is to find a reasonable (set-theoric) model of this algebra. This paper provides one.
The effects of virtual banking on the South African banking industry

Dunley-Owen, M; Hart, ML (2000)

The South African banking industry is set to undergo a complete transformation in the next ten years. One of the main reasons for this transformation is the development of virtual banking, specifically new delivery channels ...
Combining rule-based Artificial Intelligence with Geographic Information Systems to plan the physical layer of wireless networks in Greenfield areas

Prag, K; Premjeeth, P; Sandrasegaran, K (2000)

This paper elucidates the development of a computer tool which combines the use of terrain data in a Geographic Information System (GIS), an equipment database and rule-based inference. It explores the use of GJS to aid ...
Information security awareness, a must for every organization

Thomson, M; Von Solms, R (2000)

Information Technology (IT) has become part and parcel of the business world today. In fact, with the increasing sophistication of networks and the continued growth in electronic commerce, it will continue becoming an ever ...
PLaVa: a lightweight persistent Java virtual machine

Tjasink, S; Berman, S (2000)

This paper describes the implementation and tuning of an orthogonally persistent Java Virtual Machine (JVM) for small computers. It is based on a JVM that was targeted at a digital satellite television decoder with 1 ...
Cardinality constrained 0-1 Knapsack problems

Kruger, MF; Hattingh, JM; Steyn, T (2000)

The Knapsack Problem is one of the most important problems in Discrete optimization. Although it is the simplest integer program, it has numerous practical applications and often appears as a subproblem in solving more ...
