• Some current practices in evaluating IT benefits in South African organisations 

  Sutherland, F (South African Computer Society (SAICSIT), 1994)

  IT has a dynamic impact on organisations and little research has been done especially on the extent to which senior executives take the different system types into account when they appraise an IT investment. The aim of ...
• A survey of information authentication techniques 

  Smuts, WB (South African Computer Society (SAICSIT), 1994)

• Object oriented programs and a stack based virtual machine 

  Waldron, JT (South African Computer Society (SAICSIT), 2000)

  Dynamic quantitative measurements of Bytecode and Stack Frame Usage by Eiffel and Java Programs in the Java Virtual Machine are made. Two Eiffel programs are dynamically analysed while executing on the JVM, and the results ...
• Syntactic description of neighbourhood in quadtree 

  Tapamo, JR (South African Computer Society (SAICSIT), 2000)

  Region representation is very important in Graphics and Image Processing. This paper is concerned with a formalisation of image representation by quadtrees. Indeed an image here is a language over an alphabet of four ...
• Orthogonal axial line placement in chains and trees of orthogonal rectangles 

  Sanders, ID; Watts, DC; Hall, AD (South African Computer Society (SAICSIT), 2000)

  Previous research has shown that the orthogonal axial line placement problem for orthogonal rectangles is NP-complete in general but also that there are restrictions of the problem for which polynomial time solutions can ...
• Multilingual training of acoustic models in automatic speech recognition 

  Nieuwoudt, C; Botha, EC (South African Computer Society (SAICSIT), 2000)

  This paper evaluates the performance of a speech recognition system using acoustic models trained on multilingual data. The reason in our case for using data from more than one language is that there may not be enough ...
• Scalability of the RAMpage memory hierarchy 

  Machanick, P (South African Computer Society (SAICSIT), 2000)

  The RAMpage memory hierarchy is an alternative to the traditional division between cache and main memory: main memory is moved up a level and DRAM is used as a paging device. As the CPU-DRAM speed gap grows, it is expected ...
• Image coding with fractal vector quantization 

  Cloete, E; Venter, LM (South African Computer Society (SAICSIT), 2000)

  In this paper, we address the time complexity problem associated with fractal image coding. In particular, we describe a new hybrid technique called Fractal Vector Quantization (FVQ), which takes advantage of the best ...
• Technological experience and technophobia in South African university students 

  Clarke, MC (South African Computer Society (SAICSIT), 2000)

  In an earlier study co-ordinated by Weil and Rosen, university students in 23 countries were surveyed in order to compare their levels of technological sophistication and technophobia. The countries sampled did not include ...
• A new approach for program integration 

  Bouras, Z-E; Khammaci, T; Ghoul, S (South African Computer Society (SAICSIT), 2000)

  Program integration combines independent enhancements to some version of a software system into a new system that includes the enhancements and the old system. Current approaches use the slice concept. The latter is a ...
• A declarative framework for temporal discrete simulation 

  Abdulrab, H; Ngomo, M; Drissi-Talbi, A (South African Computer Society (SAICSIT), 2000)

  The aim of this paper is to introduce temporal processes and linear constraints on naturals for solving temporal discrete simulations problems. We first describe a new approach for solving such constraints, based on the ...
• An information-theoretic semantics for belief change 

  Meyer, TA (South African Computer Society (SAICSIT), 1999)

  Belief change is an interdisciplinary topic and is researched in departments of Computer Science, Artificial Intelligence, Philosophy, Mathematics and Engineering. It is therefore not surprising that there are a variety ...
• Formal verification with natural language specifications: guidelines, experiments and lessons so far 

  Holt, A (South African Computer Society (SAICSIT), 1999)

  The industrial take-up of formal verification techniques remains limited. Allowing specifications to be expressed in natural language (perhaps augmented with diagrams) offers the prospect of increasing the usability of ...
• Introducing a continuum of abstraction-led hierarchical search techniques 

  Zimmer, R; Holte, R (South African Computer Society (SAICSIT), 1999)

  Abstraction in search works by replacing a state space by another space (the abstract space) that is easier to search, either because it is smaller or because it contains more solutions. Results of searches in the abstract ...
• Understanding HCI methodologies 

  Warren, P (South African Computer Society (SAICSIT), 1999)

  The paper proposes a framework for discussing methodologies for developing interactive computer systems. It uses this framework for a sample of systems and shows how certain insights about missing aspects of the methodologies ...
• Statistical analysis of an automated computer architecture learning environment 

  Waldron, JT; Horgan, J; Keogh, G (South African Computer Society (SAICSIT), 1999)

  The level of programming skill achieved by a method of learning introductory computer architecture with a strong emphasis on assembly language programming as part of a Graduate Diploma in Information Technology in the ...
• From information security baselines to information security profiles 

  Von Solms, R; Van de Haar, H (South African Computer Society (SAICSIT), 1999)

  To protect the information systems of an organization an appropriate set of security controls needs to be installed and managed properly. Many organizations that can afford it conduct either a risk analysis exercise ...
• The CILT multi-agent learning system 

  Viktor, HL (South African Computer Society (SAICSIT), 1999)

  A multi-agent learning system consists of two or more learners or learning agents that co-exist in a learning environment. The learners have the ability to learn together, thus utilizing one another's strengths and ...
