  • Experience with a pattern-matching code generator 
    Mulders, MA Serwy, DA Van Biljon, WR (1987)
    An implementation of a Graham-Glanville type pattern-matching code generator for the NRIMS systems programming language SCRAP is discussed. The simple heuristic algorithm on which the pattern matcher is based is presented ...
  • Implication in three-valued logics of partial information 
    Britz, K (2001)
    In formal logic, both semantic entailment and the conditional connective are used to formalize the intuitive notion of implication. The former is defined in the meta-language of the logic, and the latter in the language ...
  • Finite-state computational morphology - treatment of the Zulu noun 
    Pretorius, L Bosch, SE (2001)
    Morphological analysis is a basic enabling application for further kinds of natural lan guage processing, including part-of-speech tagging, parsing, translation and other high-level applications. Automated morphological ...
  • A new algorithm for finding an upper bound of the genus of a graph 
    Carson, DI Oellermann, OR (1991)
    In this paper we discuss the problem of finding an upper bound on the genus of a graph. This problem has applications to circuit layouts. An electronic circuit may be modelled by a graph. By punching holes into the circuit ...
  • The development of a user classification model for a multi-cultural society 
    Streicher, M Wesson, JL Calitz, A (2001)
    During the last ten years, a number of computerised testing systems have been developed without considering the users' level of computer proficiency. Students at the University of Port Elizabeth come from a diverse background, ...
  • 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 ...
  • Linear response surface analysis and some applications 
    Hattingh, JM (2000)
    In general response surface analysis refers to the modeling of experimental or observational data. Computer technology and graphical techniques obviously play a significant role in the representations of these models. A ...
  • 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 ...
  • Information security management: the second generation 
    Von Solms, R (1996)
    Information security has moved a long way from the early days when physical security, together with a set of backups, fonned the backbone of a company's security controls. Today, infonnation security is all about policies, ...
  • 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 ...
  • 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 ...
  • 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 ...
