  • Cleghorn, Christopher Wesley (Springer, 2019-03)
    This paper’s primary aim is to provide clarity on which guarantees about particle stability can actually be made. The particle swarm optimization algorithm has undergone a considerable amount of theoretical analysis. ...
  • Engelbrecht, Andries P. (Springer, 2016-02)
    Since its inception in 1995, many improvements to the original particle swarm optimization (PSO) algorithm have been developed. This paper reviews one class of such PSO variations, i.e. PSO algorithms that make use of ...
  • Cleghorn, Christopher Wesley; Engelbrecht, Andries P. (Springer, 2018-03)
    This paper presents an extension of the state of the art theoretical model utilized for understanding the stability criteria of the particles in particle swarm optimization algorithms. Conditions for order-1 and order-2 ...
  • Cleghorn, Christopher Wesley; Engelbrecht, Andries P. (Springer, 2015-09)
    This paper presents an objective function specially designed for the convergence analysis of a number of particle swarm optimization (PSO) variants. It was found that using a specially designed objective function for ...
  • Cooper, A.K. (Antony Kyle); Coetzee, Serena Martha; Kourie, Derrick G. (Canadian Institute of Geomatics, 2010)
    The Internet has spawned the development of virtual communities or virtual social networks which generate and share information with one another, and with the public at large. Volunteered geographical information (VGI) ...
  • Ledwaba, Lehlogonolo P.I.; Hancke, Gerhard P.; Venter, H.S. (Hein); Isaac, Sherrin J. (Institute of Electrical and Electronics Engineers, 2018)
    In past years, cryptography has been considered a dif cult task to achieve on sensor nodes for the Internet of Energy (IoE) owing to the resource-constrained nature of 8- and 16-bit microcontroller units (MCUs). Previous ...
  • Helbig, Marde; Engelbrecht, Andries P. (Elsevier, 2013)
    When algorithms solve dynamic multi-objective optimisation problems (DMOOPs), performance measures are required to quantify the performance of the algorithm and to compare one algorithm’s performance against that of other ...
  • Helbig, Marde; Engelbrecht, Andries P. (Elsevier, 2013)
    When algorithms solve dynamic multi-objective optimisation problems (DMOOPs), performance measures are required to quantify the performance of the algorithm and to compare one algorithm’s performance against that of other ...
  • Matthysen, Wiehann; Engelbrecht, Andries P. (Elsevier, 2011-01)
    The Particle Swarm Optimisation (PSO) algorithm consists of a population (or swarm) of particles that are “flown” through an n-dimensional space in search of a global best solution to an optimisation problem. PSO operates ...
  • Ikuesan, Adeyemi Richard; Razak, Shukor Abd; Venter, H.S. (Hein); Salleh, Salleh M. (Springer, 2019-08)
    The proliferation of ubiquitous and pervasive computing devices has led to the emergence of research areas like Internet of things, and the Big-Data, which has seen a rise in obfuscation of online identity thus fueling an ...
  • Reyneke, Pieter V.; Morrison, Norman; Kourie, Derrick G.; De Ridder, Corne (KoREMA - Croatian Society for Communications, Computing, Electronics, Measurement and Control, 2012)
    Conventionally, polynomial filters are derived for evenly spaced points. Here, a derivation of polynomial filters for irregularly spaced points is provided and illustrated by example. The filter weights and variance ...
  • Gruner, Stefan (Springer, 2011-05)
    On the basis of an earlier contribution to the philosophy of computer science [Ede2007] this essay discusses to what extent the ‘paradigms’ of computer science from [Ede2007] are also applicable to software engineering, ...
  • Acton, Daniel; Kourie, Derrick G.; Watson, Bruce William (Computer Society of South Africa, 2014-07)
    As long as software has been produced, there have been e orts to strive for quality in software products. In order to understand quality in software products, researchers have built models of software quality that rely ...
  • Saadeh, Emmad I.M.; Kourie, Derrick G. (World Scientific, 2013)
    The objective of this paper is to explain the notion of fine-grain transformations (FGTs), showing how they can be used as prototypical building blocks for constructing refactorings of a design-level system description. ...
  • Pieterse, H.; Olivier, Martin S.; Van Heerden, R.P. (South African Institute of Electrical Engineers, 2016-06)
    Traces found on Android smartphones form a significant part of digital investigations. A key component of these traces is the date and time, often formed as timestamps. These timestamps allow the examiner to relate the ...
  • Coetzee, Serena Martha (Springer, 2012-01)
    A grid is concerned with the integration, virtualization, and management of services and resources in a distributed, heterogeneous environment that supports virtual organizations across traditional administrative and ...
  • Coetzee, Serena Martha (Elsevier, 2011-09)
    Standardization in the field of geographic information started in the 1990s when geographic information systems (GIS) matured and the advent of the Internet accelerated the exchange of information. Recent developments, ...
  • Ngassam, Ernest Ketcha; Ntawanga, Felix; Eloff, Jan H.P. (International Center for Information Technology and Development, 2013-04)
    The need to introduce technologies in rural areas so as to capacitate communities towards overcoming various socio-economic challenges remains a priority in emerging economies. We rely on the foregoing for the investigation ...
  • Mtshali, Mbali; Engelbrecht, Andries P. (Defence Scientific Information and Documentation, 2010-01)
    In the development of mobile robotic systems, a robotic architecture plays a crucial role in interconnecting all the sub-systems and controlling the system. The design of robotic architectures for mobile autonomous robots ...
  • Gruner, Stefan (Computer Society of South Africa, 2019-12)
    On the 5th of October 2019 I browsed the ACM-DL's database with the search key 'South Africa' in the 'conference location' field such as to obtain all ACM-DL-listed conference papers which were at any time presented in ...
