Generalized product form solutions for multiserver centres with concurrent classes of customers

Krzesinski, A.E. Crosby, S. (SAICS, 1989-11-29)

The MultiServer centre with Concurrent Classes of Customers (MSCCC) is a service centre consisting of B parallel identical exponential servers. The customers requesting service at the MSCCC centre belong to K classes. ...
Generalized product form solutions for multiserver centres with concurrent classes of customers

Krzesinski, A.E. Crosby, S. (SAICS, 1989-11-29)

The MultiServer centre with Concurrent Classes of Customers (MSCCC) is a service centre consisting of B parallel identical exponential servers. The customers requesting service at the MSCCC centre belong to K classes. ...
A comparison of assignment and matching lower bounds for the symmetric travelling salesman problem

Smith, T.H.C. Meyer, T.W.S. (SAICS, 1989-11-29)

Improved lower bounds for the Euclidean travelling salesman problem, based on the assignment relaxation, have previously been presented. We present computational experience which indicates that the (continuous) 2-matching ...
A model for conceptual views of a task realm

Short, R.C.M. (SAICS, 1989-11-29)

An earlier article in this journal argued the case for the developers of an information system, for a particular task realm, to begin the development with the determination of the conceptual views of that realm held by the ...
The representation of chemical structures by using structure graph grammars

Ehlers, E.M. Von Solms, S.H. Tew, A.W. (SAICS, 1989-11-29)

The use of graph grammars in modeling three dimensional structures is discussed. Two extensions of graph grammars are proposed. Structure graph grammars generate three dimensional structure graphs. The representation of ...
A systematic method for synthesis of asynchronous machines using Interface Protocol Asynchronous Cell (IPAC) PAL device

Aghdasi, F. (SAICS, 1989-11-29)

A novel method of designing asynchronous sequential circuits is introduced which lends itself to implementation by edge sensitive flip-flops in a manner that edge sensitive inputs and level sensitive signals can be combined. ...
Structuring hypertext

Barrow, J. (SAICS, 1989-11-29)

With the many new opportunities for text-handling created by the associative form of hypertext come the possible user problems of disorientation, high cognitive load, and low precision access. The possibility of dynamic ...
Predicting the performance of shared multiprocessor caches

Goosen, H.A. Cheriton, D.R. (SAICS, 1989-11-29)

We investigate the performance of shared caches in a shared-memory multiprocessor executing parallel programs, and formulate simple models for estimating the load placed on the bus by such a shared cache. We analyze three ...
Towards a general cell silicon compiler

Moosa, M.S. Levy, D.C. (SAICS, 1989-11-29)

This paper provides an overview of a general cell silicon compiler being developed at the University of Natal. The individual components, together with their motivation, are presented. No attempt is made to provide explicit ...
Proceedings of the 5th/Vth Southern African Computer Symposium, Holiday Inn, Sandton, 29 November - 1 December 1989 (Full book)

Kritzinger, P. (Ed.) (SAICS (South African Institute of Computer Scientists), 1989-11-29)
Integrated network management

Roos, J.D. Von Backström, L. (SAICS, 1989-11-29)

Over the last decade, networks have evolved into sophisticated, multi-vendor, multi-protocol networks, which need to be properly managed and protected. The preferred way of accomplishing this, is through Integrated Network ...
A protocol engineering workstation - with an application to protocol performance analysis

Kritzinger, P.S. Wheeler, G. (SAICS, 1989-11-29)

This paper describes the Protocol Engineering Workstation (PEW), an integrated specification, debugging and testing package based upon the Estelle FDT. It consists of three primary integrated components: a screen editor, ...
Ecological applications using a novel expert system shell

Riordan, D. Bradshaw, J.A. Carden, K.J. (SAICS, 1989-11-29)

Much of the information used by ecologists in modeling and decision making is imprecise. The imprecision arises both from data which is inexact or incomplete and from the use of ecological principles which are sometimes ...
Proceedings of the 5th Southern African Computer Symposium, 1989 (Frontmatter)

Kritzinger, Pieter (Editor) (SAICS, 1989-11-29)

Experience with the development of a neural network simulator

Cloete, I. Ludik, J. (SAICS, 1989-11-29)

Researchers experimenting with structured neural networks must be able to implement and test their ideas. Since most of the network models presume much structure, and network architecture design is a major component in ...
The case for functional programming

Wentworth, E.P. (SAICS, 1989-11-29)

Functional programming has gained a foothold in academic institutions, and the first commercial interests have been noted. The paradigm is presented by way of some small examples, and arguments are given in favour of this ...
A pipelined control strategy for inferencing

Kourie, D.G. Potgieter, A.E.G. (SAICS, 1989-11-29)

The task of deriving a solution to a goal from a Hom clause database is seen in terms of finding a solution tree as a subtree of an and/or tree. The way in which various well-known control strategies derive such solutions ...
Data structuring via functions

Venter, B.H. (SAICS, 1989-11-29)

A programming language data model is introduced, based on the notions that variables are functions and types are sets of values. It is shown that, despite the simplicity of the underlying mathematical formalism, the data ...
Object-oriented systems, so what?

Barth, Gerhard (SAICS, 1989-11-29)
Induction of decision trees in a domain with continuous attributes

Cloete, I. Theron, H. (SAICS, 1989-11-29)

Quinlan's ID3 is a popular and efficient algorithm for inducing decision trees from concept examples, where the examples are presented as vectors of attribute-value pairs. For attributes with large, continuous domains ID3 ...
