  • Makinana, S; Malumedzha, T; Nelwamondo, Fulufhelo V (AIRCC, 2015-01)
    Iris recognition systems have attracted much attention for their uniqueness, stability and reliability. However, performance of this system depends on quality of iris image. Therefore there is a need to select good quality ...
  • Mngenge, NA; Nelwamondo, Fulufhelo V; Malumedzha, T; Msimang, N (Springer-Verlag, 2012-06)
    The need for segmentation of low quality fingerprints in forensics, high security and civilian applications is constantly increasing. Most segmentation algorithms proposed in the literature normally deal with separation ...
  • Lorgat, MW; Baghai-Wadji, A; McDonald, Andre M (IEEE, 2017-10)
    The performance loss due to incomplete information in denial of service (DoS) detection is quantified in this paper. Volumetric DoS detection is formulated as a signal detection problem. Two detectors are defined: the first ...
  • Le Roux, Alize (University of Utrecht, The Netherlands, 2012-08)
    Land use policies have a definite and lasting impact on the way that cities grow, however, the change in land use only gets observed many years later. As such, it is difficult for policy and decision makers to observe and ...
  • Bachoo, AK; De Villiers, JP; Nicolls, F; Le Roux, Francois PJ (2011-04)
    This work aims to evaluate the improvement in the performance of tracking small maritime targets due to real-time enhancement of the video streams from high zoom cameras on pan-tilt pedestal. Due to atmospheric conditions ...
  • Mabaso, M; Twala, B; Withey, Daniel J (IEEE, 2013-09)
    Tracking of multiple bright particles (spots) in fluorescence microscopy image sequences is seen as a crucial step in understanding complex information in the cell. However, fluorescence microscopy generates high a volume ...
  • Jamison, Kevin A; Rossouw, Pieter S; Miles, Elizna (2017-09)
    When a new store is integrated with an aircraft, it is necessary to verify that it separates safely for all possible release and emergency jettison scenarios. A large number of store separation analyses are required to ...

  • Bogaers, Alfred EJ; Kok, S; Reddy, BD; Franz, T (Elsevier, 2014-09)
    In this paper we introduce a new multi-vector update quasi-Newton (MVQN) method for implicit coupling of partitioned, transient FSI solvers. The new quasi-Newton method facilitates the use of 'black-box' field solvers and ...
  • Haelterman, R; Bogaers, Alfred EJ; Degroote, J; Boutet, N (International Association of Engineers, 2017-08)
    Often in nature different physical systems interact which translates to coupled mathematical models. Even if powerful solvers often already exist for problems in a single physical domain (e.g. structural or fluid problems), ...
  • Klarman, S; Meyer, T (Springer, 2014-06)
    SQL:2011, the most recently adopted version of the SQL query language, has unprecedentedly standardized the representation of temporal data in relational databases. Following the successful paradigm of ontology-based data ...
  • Henriques, R; Lelek, M; Fornasiero, EF; Valtorta, F; Zimmer, C; Mhlanga, Musa (Nature Publishing Group, 2010-05)
    QuickPALM in conjunction with the acquisition of control features provides a complete solution for the acquisition, reconstruction and visualization of 3D PALM or STORM images, achieving resolutions of ~40 nm in real time. ...
  • Loveday, Philip W; Long, Craig S (2019-12)
    Ultrasonic guided waves have been shown to propagate large distances in continuously welded rail track.
  • Mguda, Z; Faltenbacher, A; Van der Heyden, K; Gottlöber, S; Cress, C; Vaisanen, P; Yepes, G (Oxford University Press, 2015-01)
    In this paper we use the MareNostrum Universe Simulation, a large scale, hydrodynamic, non-radiative simulation in combination with a simple abundance matching approach to determine the ram pressure statistics for bent ...
  • Perlow, J; Rosman, Benjamin S; Hayes, B; Ranchod, P (2017-11)
    An important step in the construction of novel objects is the ability to recognise combinations of raw materials which are likely to be useful. We aim to exploit the intuition that the visual characteristics of candidate ...
  • Nortje, R; Britz, K; Meyer, T (Springer Verlag, 2013-12)
    In this paper we investigate module extraction for the Description Logic SRIQ. We formulate modules in terms of the reachability problem for directed hypergraphs. Using inseperability relations, we investigate the ...
  • Das, Sonali; Gupta, R; Kanda, PT; Reid, M; Tipoy, CK; Zerihun, MF (Springer US, 2012-12)
    The real interest rate is a very important variable in the transmission of monetary policy. It features in vast majority of financial and macroeconomic models. Though the theoretical importance of the real interest rate ...
  • Gopal, Ajith K; Wium, Elsmari (Inderscience Publishers, 2019-08)
    The application of a modified A-star (A*) global search algorithm and trajectory planner based on the tentacles algorithm approach are investigated for real-time path and trajectory planning on an unmanned ground vehicle ...
  • Page, Philip R; Abu-Mahfouz, Adnan MI; Yoyo, S (Elsevier, 2016-08)
    Remote real-time control is currently the most advanced form of pressure management. Here the parameters describing pressure control valves (or pumps) are changed in real-time in such a way to provide the most optimal ...
  • Osman, Muhammad S; Yoyo, S; Page, Philip R; Abu-Mahfouz, Adnan MI (ACTA Press, 2016-09)
    It is known that South Africa is a water scarce country which has been recently been experiencing erratic weather conditions resulting in a constrained water supply. Renewed focus has been placed on water conservation. ...
