  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
