  • Concept network framework for a multi-paradigm knowledge base 
    Kambanis, J (South African Institute of Computer Scientists and Information Technologists, 1991)
    This paper describes a conceptual framework and an implementation medium for constructing multi-paradigm knowledge bases. The idea of a concept network is used as a basis for storing knowledge in different knowledge ...
  • A conceptual design for high-volume data processing of warehouse database into multidimensional database 
    Trakulsuk, P; Avatchanakorn, V (South African Computer Society (SAICSIT), 1999)
    This paper presents a conceptual model of analyzing huge amount of information from a data warehouse into Multidimensional Database (MDDB) using multidimensional data (MDD)model. The major advantages of this model are: 1) ...
  • Conceptual design of a glycerol biorefinery 
    Mukeru, Bahizire Martin (2021-12)
    Glycerol is considered as the major waste from biodiesel production since every 1L of biodiesel produced is accompanied by 0.1 L of glycerol by-product. Utilizing this waste as a biorefinery feedstock will not only ...
  • Conceptual design of gasification-based biorefineries using the C-H-O ternary diagram 
    Litheko, Lefu Andrew (2017-10)
    This dissertation develops a systematic targeting method based on the C-H-O ternary diagram for the conceptual design of gasification-based biorefineries. The approach is applied using dimethyl ether (DME) as case study. ...
  • A conceptual framework for a student personal information privacy culture at universities in Zimbabwe 
    Da Veiga, Adele; Martins, Nico; Maguraushe, Kudakwashe (Kalpa Publications in Computing, 2019)
    In this research, an information privacy culture is proposed to be embedded in three basic concepts: students’ privacy expectations, privacy awareness and confidence in universities’ capability to uphold information privacy. ...
  • A Conceptual Framework for the Development of Argumentation Skills Using CSCL in a Graduate Students’ Research Course 
    van der Merwe, O. R.; Van Biljon, Judy; Pilkington C, / (Springer, 2022-07-07)
    Developing and presenting a well-formulated research argument is core to the learning journey of a graduate student. In open distance e-learning, computer-supported learning is instrumental in providing a platform for ...
  • A Conceptual Information Security Culture Framework for Higher Learning Institutions 
    Ocloo, Charles; Kroeze, Jan H; Da Veiga, Adele (Springer, Cham, 2021-07)
    Education institutions within and outside Ghana continue to experience mass information leakages at an alarming rate even with the huge investment made in information technology infrastructure to secure their information ...
  • A conceptual model for the adoption and use of CASE technology 
    Huisman, HM (1998)
    The software crisis has been well documented. Software is being delivered late, over budget and full of residual faults. In an attempt to solve these problems, CASE technology has been developed. CASE technology provides ...
  • A Conceptual Model of the Research Methodology Domain 
    Pilkington, Colin; Pretorius, Laurette (SCITEPRESS, 2015-11)
    Recognising the need for the development of research capacity and changing learning paradigms that include online and collaborative approaches, an ontology of research methodology needs to be developed to allow for the ...
  • A CONCEPTUAL OPPORTUNITY-BASED FRAMEWORK TO MITIGATE THE INSIDER THREAT 
    Padayachee, Keshnee (2014-01-29)
    Abstract: The aim of this paper is to provide a conceptual framework to mitigate the insider threat from an opportunity-based perspective. Although both motive and opportunity are required to commit maleficence, this paper ...
  • Concern for information privacy in South Africa: An empirical study using the OIPCI 
    Da Veiga, Adele (Springer, Cham, 2020)
    The information privacy concern of consumers concerning the processing of their personal information by online organizations (websites) is investigated in this study by means of a quantitative approach. An overview of ...
  • Concern for Information Privacy: A Cross-Nation Study of the United Kingdom and South Africa 
    Da Veiga, Adele; Ophoff, Jacques (Springer, IFIP Advances in Information and Communication Technology, Human Aspects of Information Security and Assurance 14th IFIP WG 11.12 International Symposium, HAISA 2020, Mytilene, Lesbos, Greece, July 8–10, 2020, Proceedings, 2020-07-08)
    Abstract. Individuals have differing levels of information privacy concern, formed by their expectations and the confidence they have that organisations meet this in practice. Variance in privacy laws and national factors ...
  • Concern for Information Privacy: A Cross-Nation Study of the United Kingdom and South Africa 
    Da Veiga, Adele; Ophoff, Jacques (Springer, Cham, 2020)
    Individuals have differing levels of information privacy concern, formed by their expectations and the confidence they have that organisations meet this in practice. Variance in privacy laws and national factors may also ...
  • Concerning ideals of pointfree function rings 
    Ighedo, Oghenetega (2013-11)
    We study ideals of pointfree function rings. In particular, we study the lattices of z-ideals and d-ideals of the ring RL of continuous real-valued functions on a completely regular frame L. We show that the lattice of ...
  • Concurrency control mechanisms for multidatabase systems 
    Deacon, A (1991)
    In conventional systems, transaction management has been thoroughly investigated and is now considered to be well understood. Transaction management in multidatabase systems, however, is less well understood. A multidatabase ...
  • Concurrency: An Easier Way to Program 
    Mueller, C.S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Why concurrency in itself should be seen as a method of programming, is discussed. Current approaches to concurrent programming are evaluated in terms of e~e qt programming. The properties required to decompose the ...
  • Congo Red Dye Removal by Direct Membrane Distillation using PVDF/PTFE Membrane
