  • The NRDNIX distributed database management system 
    Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1990)
    A distributed database management system must facilitate integrated processing of data which is physically distributed over a network of node computers, while providing locality transparency. The NRDNIX prototype has ...
  • The use of a lattice for fast pattern matching 
    Oosthuizen, GD (South African Institute of Computer Scientists and Information Technologists, 1990)
    Pattern recognition involves the matching of a given pattern against a collection of patterns in store in order to identify the given pattern as belonging to a particular class already known to the system or not. Similarly, ...
  • Image reconstruction via the Hartley transform 
    Murrell, HC Carson, D (South African Institute of Computer Scientists and Information Technologists, 1990)
    The continuous and discrete Hartley transforms are real valued transforms that have similar properties to the continuous and discrete Fourier transforms. In addition, a fast algorithm exists for computing the discrete ...
  • Programming using induction 
    Mueller, C.S.M. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Induction has been used as a major tool in mathematics in proving theorems. This paper explores whether it has an equally important role in formulating programs. There are those who advocate that induction should be used ...
  • A multi-criteria partitioning technique for information system design 
    Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    In order to design and operate a complex computer based information system, one needs to partition its transformation process into modules of manageable size. The same process can be partitioned in many different ways, ...
  • Four major success criteria for information system design 
    Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Both in the advancement of Information Systems theory and in practical development projects, significant errors of omission can occur unless one is aware of all aspects of the concept "information system success". At least ...
  • An Estelle compiler for a protocol development environment 
    Kritzinger, PS van Dijk, J (South African Institute of Computer Scientists and Information Technologists, 1990)
    The development of communication protocol standards has been accompanied by the standardization of formal specification languages to describe these standards in a clear and unambiguous way. Simulta­neously, techniques for ...
  • A design environment for semantic data models 
    Kambanis, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    This paper describes the functionality and architecture of a Semantic Data Modeling environment. It integrates User Interface techniques used in Computer Aided Software Engineering-and Expert Systems shells into a system ...
  • Challenges Botswana’s Mobile Application Developers Encounter: Funding, Commercial and Technical Support 
    Nyamaka, Admore Botha, Adele Van Biljon, Judy Marais, Mario (IIMC International Information Management Corporation, 2018)
    Smart phone usage in Sub-Saharan Africa is expected to constitute more than half of all mobile connections by 2020. Therefore, it can be expected that mobile applications will change the way business is conducted and ...
  • Demarcating mobile phone interface design guidelines to expedite selection 
    Renaud, Karen Van Biljon, Judy (South African Institute of Computer Scientists and Information Technologists, 2017-12)
    Guidelines are recommended as a tool for informing user interface design. Despite a proliferation of guidelines in the research literature, there is little evidence of their use in industry, nor their influence in academic ...

  • Fourier-plane modeling of the jet in the nucleus of galaxy M81 
    Ramessur, Arvind (2017-12)
    The mildly active nuclear region in the galaxy M81 (henceforth, M81‹) is one of the nearest low-luminosity active galactic nuclei (LLAGN) whose structure is marginally resolved when probed with Very Long Baseline ...
  • QUAESTIONES INFORMATICAE VOL 3 
    SAICSIT (SAICSIT, 1985)
  • Knowledge management and its effectiveness for organisational transformation through knowledge sharing and transfer 
    Mazorodze, Alfred Hove (2017-06)
    Knowledge Management aims to improve organisational performance and it marks the beginning of organisational transformation. The two types of knowledge managed are respectively categorised “tacit” and “explicit.” This ...
  • Addressing ambiguity within information security policies in higher education to improve compliance 
    Buthelezi, Mokateko Portia (2017-06)
    nformation security (InfoSec) policies are widely used by institutions as a form of InfoSec control measure to protect their information assets. InfoSec policies are commonly documented in natural language, which is prone ...
