  • Baart, L; McLeod, R (2000)
    R.A. Liming developed a method based on classical conic section theory to design cross-sections of aircraft using implicit rather than explicit forms of the quadratic equations. In its basic form the method is used to ...
  • Oosthuysen, WH; McDonald, T (South African Computer Society (SAICSIT), 1995)
    Until some years ago, management of TCP/IP based products was done in a proprietary fashion. Many large companies build their own system-wide management facilities because of a lack of usable systems to manage heterogeneous ...
  • Hazelhurst, SE (South African Institute of Computer Scientists and Information Technologists, 1991)
    The dining philosophers problem and the evolving philosophers problems are abstractions of resource sharing problems in parallel and distributed systems. A Linda solution to the dining problem has already been shown; this ...
  • Kubeka, Amos Soweto (2013-02)
    We firstly numerically recalculate the Ricci tensor of non-stationary axisymmetric space-times (originally calculated by Chandrasekhar) and we find some discrepancies both in the linear and non-linear terms. However, ...
  • 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 ...
  • Mata-Montero, M; Ellis, JA (South African Computer Society (SAICSIT), 1994)
    The Longest (s-t)-path Problem, a known NP-complete set, is shown to admit a linear time solution when the instances of the problem are restricted to partial k-trees. This class of graphs is defined and some of the properties ...
  • Kritzinger, Pieter S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Current scientific and trade literature are flooded with information about local area networks. Details about physical media and their properties, versions of media access methods confusingly called protocols, variations ...
  • Ibrahim, Rabha W; Jafari, Hossein; Jalab, Hamid A; Hadid, Samir B (2019-03-06)
    Abstract The economic order quantity (EOQ) model describes the quantity that minimizes the aggregate sum of all cost functions. We propose an assembly for EOQ, nonlinear local fractional differential models ...
  • De Wet, Johan Pieter (2016-10)
    We say a graph is locally P if the induced graph on the neighbourhood of every vertex has the property P. Specically, a graph is locally traceable (LT) or locally hamiltonian (LH) if the induced graph on the neighbourhood ...
  • Misra, J (South African Computer Society (SAICSIT), 1998)
    This paper presents a short introduction to the UNITY logic, a fragment of linear temporal logic. The logic was designed to specify safety and progress properties of reactive systems. A version of the UNITY ...
  • Labuschagne, W.A.; Van der Westhuizen, PL (South African Computer Society (SAICSIT), 1992)
    The logician who encounters logic programming expects it to involve 'using predicate logic as a programming language'. He is soon disillusioned. He discovers that it really means 'programming in PROLOG', which in tum seems ...
  • Viljoen, Elizabeth (1997-04)
    The inadequacy of the usual possible world semantics of modal languages when the meaning of 'belief' is attached to the modal operator is discussed. Three other approaches are then investigated. In the case of Moore's ...
  • Masamha, Tavengwa (2020-02)
    Information and communication technology (ICT) greatly influence today’s business processes be it in public or private sectors. Everything that is done in business requires ICT in one way or the other. Research in ICTs ...
  • Muchabaiwa, Honest (2013-02)
    This thesis investigates the factors that are associated with annual changes in the share price of Johannesburg Stock Exchange (JSE) listed companies. In this study, an increase in value of a share is when the share price ...
  • Ranganai, Edmore; Kubheka, Sihle B (2016-12-09)
    Abstract South Africa is a cornucopia of the platinum group metals particularly platinum and palladium. These metals have many unique physical and chemical characteristics which render them indispensable to ...
  • Kubheka, Sihle (2016-11)
    South Africa is rich in platinum group metals (PGMs) and these metals are important in providing jobs as well as investments some of which have been seen in the Johannesburg Securities Exchange (JSE). In this country this ...
  • Berezner, SA; Krzesinski, AE (1995)
    Consider a circuit-switched network where several source switches are connected to a destination switch via a tandem switch. Circuit-switched networks traditionally employ a Blocked Calls Cleared ( BCC) admission rule: a ...
  • Olwal, T.; Van Wyk, M. A.; Chatelain, D.; Odhiambo, M.; Van Wyk, B. J. (2009)
    This paper presents a fast converging timing recovery algorithm for digital receivers in low signal to noise ratio. This solves the problem of traditional slow converging phase-locked loop-based timing recovery in low ...
  • Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    There has been a proliferation of low-cost AI tools. Consideration is given as to how significant research may be conducted using these tools, in the light of experience of developing Al tools on large, expensive machines. ...
  • 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 ...
