  • Nitroxide polymer mediated oxidation of cellulose : preparation and applications 
    Sun, Tingting (2022-03)
    2, 2, 6, 6-Tetramethylpiperidine-N-oxyl radical (TEMPO) is a stable nitroxyl radical, as well as a highly efficient selective oxidation catalyst. It can efficiently catalyze the selective oxidation of C6 primary hydroxyl ...
  • Non-orthogonal ray guarding 
    Sanders, I (1998)
    In an earlier paper the notion of a ray guard --'- a guard that can only see along a single ray, was introduced. The ray guarding problem is in siting the fewest possible such guards so that they guard all adjacencies ...
  • Non-resonant microwave absorption studies in SmFeAs(O,F) iron pnictide superconductor 
    Onyancha, Robert Birundu (2015-03)
    As an electromagnetic response detection technique, non-resonant microwave absorption (NRMA) has been without doubt, one of the fundamental tools in characterizing high temperature superconductors (HTSC). The technique can ...
  • Non-response error in surveys 
    Taljaard, Monica (1997-06)
    Non-response is an error common to most surveys. In this dissertation, the error of non-response is described in terms of its sources and its contribution to the Mean Square Error of survey estimates. Various response and ...
  • Novel chitosan/gold-MPA nanocomposite for sequence-specific oligonucleotide detection 
    Cao, S.; Mishra, R.; Pilla, S.; Tripathi, S.; Pandey, M.K.; Shah, G.; Mishra, A.K.; Prabaharan, M.; Mishra, S.B.; Xin, J.; Pandey, R.R.; Wu, W.; Pandey, A.C.; Tiwari, A. (2010)
  • Novel Kuhn-Tucker conditions for vibration analysis in a functionally graded porous beam using the R-program 
    Geetha, Narayanan; Vivekanandam, Balasubramaniam; Pappula, Bridjesh; Makgato, Seshibe (Elsevier, 2024-03-29)
    Functionally graded materials provide a flexible and individualized strategy for material design, allowing for optimization of properties and performance for particular purposes. The investigation considers the effects of ...
  • Novice attitude changes during a first course In computing: a case study 
    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes a study of changes in attitude toward computers exhibited by novice student users during a first course in business computing. Several dimensions of attitude were established by factor analysis. ...
  • Novice researchers' perspectives on affordances in ICT4D research collaboration 
    Mwapwele, Samwel; Van Biljon, Judy (John Wiley & Sons Ltd, 2021)
    Collaboration is fundamental to progress in the field of information and communication technologies for development (ICT4D) research where interdisciplinary teams are involved in the requirements elicitation, design, ...
  • 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 ...
  • Nuclear reactions inside the water molecule 
    Dicks, Jesse (2005-06)
    A scheme, analogous to the linear combination of atomic orbitals (LCAO), is used to calculate rates of reactions for the fusion of nuclei con¯ned in molecules. As an example, the possibility of nuclear fusion in rotationally ...
  • Numerical solution of multiband k.p model for tunneling in type-II heterostructures. 
    Botha, A.E. (OpenJournals Publishing, 2009-07)
    A new and very general method was developed for calculating the charge and spin-resolved electron tunnelling in type-II heterojunctions. Starting from a multiband k.p description of the bulk energy-band structure, a multiband ...
  • Object orientation in relational databases 
    Rennhackkamp, M (1991)
    There is, as yet, no single formal definition for the object-oriented approach. The object-oriented paradigm is described in terms of the concepts accentuated by the approach, namely classes, objects, methods, messages and ...
  • Object oriented database management systems 
    Nassis, Antonios (1995-11)
    Modern data intensive applications, such as multimedia systems require the ability to store and manipulate complex data. The classical Database Management Systems (DBMS), such as relational databases, cannot support these ...
  • Object oriented programs and a stack based virtual machine 
    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 ...
  • Object-oriented business modelling and re-engineering 
    Watzenboeck, M (2000)
    Financial industry and manufacturing are the main customers in migrating existing applications into client server environments. This paper helps in identifying the candidates for migration and suggests a method for ...
  • Object-oriented development: knowledge base support for design 
    Loock, M; Steenkamp, AL (1995)
    The research is conducted in the area of Software Engineering, with emphasis on the design phase of the Software Development Life Cycle (SDLC). The object-oriented paradigm is the point of departure. The investigation deals ...
  • An object-oriented framework for rapid client-side integration of information management systems 
    Schimkat, RD; Kuchlin, W; Krautter, R (South African Computer Society (SAICSIT), 1999)
    Reuse of software components offers the potential for significant savings in application development costs and time. This paper provides a characterization of reuse at different levels of client-based software in distributed ...
  • The object-oriented paradigm: Uncertainties and insecurities 
    Schach, Stephen R. (South African Computer Society (SAICSIT), 1994)
    The object-oriented paradigm is widely promoted as the optimal way to develop software. However, there is as yet no experimental evidence to back that assertion, and it is extremely unlikely that such evidence could be ...
  • An object-oriented strategy for banking 
    Daratos, J; Steenkamp, AL (1995)
    Many information strategists today agree that the Object-Oriented Technology (OOT) has particular requirements that should not be omitted from a traditional Information Technology (IT) strategy. An Object-Oriented Strategy ...
  • OCTOLISP: An experiment with data structures 
    Dempster, Robert (South African Institute of Computer Scientists and Information Technologists, 1990)
    OCTOLISP is a functional programming language which provides the programmer with a number of explicit data structures, such as lists, stacks, vectors, sets, trees and forests. Each of these data structures also has a ...
