  • Gruner, Stefan; Bartelmann, Matthias (Cosmos and History Publishing Co-op, 2015)
    Hegel's historically transient notion of 'aether', developed and finally abandoned again during his short period of time at the University of Jena in the early years of the 19th century, has received comparatively little ...
  • Kebande, V.R. (Victor); Venter, H.S. (Hein) (Taylor and Francis, 2018)
    This paper examines the design and implementation of a feasible technique for performing Digital Forensic Readiness (DFR) in cloud computing environments. The approach employs a modified obfuscated Non-Malicious Botnet ...
  • Schoeman, I.L.; Engelbrecht, Andries P. (Springer, 2010-09)
    Several techniques have been proposed to extend the particle swarm optimization (PSO) paradigm so that multiple optima can be located and maintained within a convoluted search space. A significant number of these impl ...
  • Adeyemi, Ikuesan Richard; Razak, Shukor Abd; Salleh, Mazleena; Venter, H.S. (Hein) (Public Library of Science, 2016-12-05)
    Comprehension of the statistical and structural mechanisms governing human dynamics in online interaction plays a pivotal role in online user identification, online profile development, and recommender systems. However, ...
  • Van Staden, W.J.S. (Wynand Johannes Christiaan); Olivier, Martin S. (Graz University of Technology, 2011-02-01)
    This paper puts forward a verification method for compound purposes and compound reasons to be used during purpose limitation. When it is absolutely necessary to collect privacy related information, it is essential ...
  • Kebande, V.R. (Victor); Venter, H.S. (Hein) (Taylor and Francis, 2018)
    The need to perform digital investigations has over the years led to the exponential growth of the field of Digital Forensics (DF). However, quite a number of challenges face the act of proving – for purposes of Digital ...
  • Gravell, Andy M.; Gruner, Stefan (Computer Society of South Africa, 2018-07)
    Half a century after the emergence of computer science (a.k.a. informatics) as an academic discipline, the notion of ‘computation’ is not yet ‘settled’. On the contrary: recent developments in the natural sciences, in ...
  • Gruner, Stefan (Vaal Triangle Faculty of Northwest University in South Africa, 2014-07)
    This study outlines in some detail the semantic variety of the notion of 'software architecture' in the field of software engineering since the early 1970s. This paper shows that there are two schools of thought in software ...
  • Harrison, Kyle Robert; Engelbrecht, Andries P.; Ombuki-Berman, Beatrice M. (Elsevier, 2018-08)
    The particle swarm optimization (PSO) algorithm is a stochastic search technique based on the social dynamics of a flock of birds. It has been established that the performance of the PSO algorithm is sensitive to the values ...
  • 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 ...

  • 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 ...
