  • The case for a multiprocessor on a Die: MoaD 
    Machanick, P (2001)
    Increasingly aggressive pipelining achieves diminishing returns. Simultaneous Multi-threading (SMT) attempts to exploit the fact that functional units are frequently idle. This paper argues the case for keeping the processor ...
  • Combining context provisions with graph grammar rewriting rules - the three-dimensional case 
    Barnard, A; Ehlers, EM (2001)
    In this paper we consider the representation and generation of three-dimensional structures by means of formal descriptive methods. Graph and graph grammar theory present us with a powerful two-dimensional representational ...
  • A comparison of the interface effect on the use of mobile devices 
    Franken, J; Stander, A; Booley, Z; Isaacs, Z; Rose, R (2001)
    Designers of mobile systems continue to focus on transferring the typical workstation environment as prevalent on the desktop PC to mobile devices. The lack of specific focus on the requirements of the wireless platforms ...
  • Computer security: hacking tendencies, criteria and solutions 
    Botha, M; Von Solms, R (2001)
    Computer crime and more particularly computer hacking has become increasingly active in today's business environment. Proof of this statement is a survey completed by the Computer Security Institute and the FBI which ...
  • Creating high performance IS teams 
    Smith, DC; Becker, M; Burns-Howell, J; Kyriakides, J (2001)
    The use of teams within organisations is becoming more prevalent as teams have been identified as an efficient work unit of human capital. This research identified 17 team effectiveness characteristics and, using a sample ...
  • 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, ...
  • The effect of colour, luminance, contrast, icons, forgiveness and closure on ATM interface efficiency 
    Stander, A; Van Zee, P; Wang, Y-J (2001)
    Automatic teller machines (ATM) are an intermediate stage in the progression of banking technology. This intermediate stage is expected to remain until user perceptions of electronic banking have improved. ATM transaction ...
  • Effectively exploiting server log information for large scale web sites 
    Wong, B; Marsden, G (2001)
    With the continuing growth of the Internet, an increasing number of organisations are incorporating the Web into their business activities. The appeal of a site to users in terms of both attractiveness and usability ...
  • The effects of avatars on co-presence in a collaborative virtual environment 
    Casanueva, J; Blake, E (2001)
    Presence in Collaborative Virtual Environments (CVEs) can be divided into personal presence and co-presence. Personal presence is having a feeling of "being there" in the CVE oneself. Co-presence is having a feeling that ...
  • Finding adjacencies in non-overlapping polygons 
    Adler, J; Christelis, GD; Deneys, JA; Konidaris, GD; Lewis, G; Lipson, AG; Phillips, RL; Scott-Dawkins, DK; Shell, DA; Strydom, BV; Trakman, WM; Van Gool, LD (2001)
    Two polygons are adjacent if they have edges which share a common edge segment. In this paper we consider the problem of finding adjacencies in a set of n non-overlapping polygons. Using the fact that adjacent edges must ...
  • 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 ...
  • Formal usability testing - informing design 
    Van Greunen, D; Wesson, J (2001)
    The goal of this paper is to discuss the role of usability testing in software development in South Africa. Throughout the software industry software engineers develop user interfaces (Ul) with little or no support from ...
  • Further cache and TLB investigation of the RAMpage memory hierarchy 
    Machanick, P; Patel, Z (2001)
    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. Earlier RAMpage work has shown that the RAMpage ...
  • Hierarchical level of detail optimization for constant frame rate rendering of radiosity scenes 
    Nirenstein, S; Blake, E; Winberg, S; Mason, A (2001)
    The predictive hierarchical level of detail optimization algorithm of Mason and Blake is experimentally evaluated in the form of a practical application to hierarchical radiosity. In a novel approach the recursively ...
  • 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 ...
  • The influence of facilitation in a group decision support systems environment 
    Nepal, T; Petkov, D (2001)
    Organisations today face many issues that are complex and ill structured. The complexity of these issues does not lend themselves to structuring and formulation by quantitative models, or simple intuitive problem solving. ...
  • Information security development trends 
    Von Solms, E; Eloff, JHP (2001)
    Information is a very valuable resource and must be protected against harmful attacks from inside as well as outside the organization. As a resource, information is the lifeline of many organizations and is therefore vital ...
