  • Oxtoby, Oliver F; Malan, AG (2011-01)
    The authors describe the development of a 3D parallel Fluid–Structure–Interaction (FSI) solver and its application to benchmark problems. Fluid and solid domains are discretised using and edge-based finite-volume scheme ...
  • Chavez-Santiago, R; Szydelko, M; Kliks, A; Foukalas, F; Haddad, Y; Nolan, KE; Kelly, MY; Masonta, MT; Balasingham, I (Springerlink, 2015-03)
    As the rollout of 4G mobile communication networks takes place, representatives of industry and academia have started to look into the technological developments toward the next generation (5G). Several research projects ...
  • Halland, K; Britz, K (ACM, 2012-10)
    The formal definition of abduction asks what needs to be added to a knowledge base to enable an observation to be entailed by the knowledge base. ABox abduction in description logics (DLs) asks what ABox statements need ...
  • Malan, AG; Oxtoby, Oliver F (Elsevier, 2012-09)
    In this paper we propose a fast, parallel 3D, fully-coupled partitioned hybridunstructured finite volume fluid–structure-interaction (FSI) scheme. Spatial discretisation is effected via a vertex-centered finite volume ...
  • Makondo, Ndivhuwo; Rosman, Benjamin S; Hasegawa, O (2018-05)
    Online learning of a robot’s inverse dynamics model for trajectory tracking necessitates an interaction between the robot and its environment to collect training data. This is challenging for physical robots in the real ...
  • Gerber, A; Sinha, S; Van der Merwe, A; Kam, M (IEEE, 2012-05)
    Over the past two decades, strong technical convergence has been observed between computing and engineering. Computing in this context includes Computer Engineering, Computer Science, Information Systems, Information ...
  • Andhavarapu, EV; Loveday, P; Long, CS; Heyns, PS (SACAM 2010, 2010-01)
    The semi-analytical finite element method (SAFE) is a popular method for analysing guided wave propagation in elastic waveguides of complex cross-section such as rails. The convergence of these models has previously been ...
  • Rosman, Benjamin S; Ramamoorthy, S (IEEE Xplore, 2015-04)
    An agent tasked with solving a number of different decision making problems in similar environments has an opportunity to learn over a longer timescale than each individual task. Through examining solutions to different ...
  • Govender, Nicolin; Claassens, J; Nicolls, F; Warrell, J (IEEE Xplore, 2013-01)
    For mobile robots to perform certain tasks in human environments, fast and accurate object classification is essential. Actively exploring objects by changing viewpoints promises an increase in the accuracy of object ...
  • Burger, CR; Jones, T (IASSA, 2011-09)
    As unmanned aircraft are introduced into civil airspace, a framework for training and licencing of dispatch and operating staff will be required. This paper assesses existing pilot training unit standards and proposes a ...
  • Hassan Mahmud, MM; Rosman, Benjamin S; Ramamoorthy, S; Kohli, P (2014-06)
    Interactive interfaces are a common feature of many systems ranging from field robotics to video games. In most applications, these interfaces must be used by a heterogeneous set of users, with substantial variety in ...
  • Setshedi, Itumeleng; Long, Craig S; Loveday, Philip W; Wilke, Daniel N (SACAM, 2018-09)
    Permanently installed monitoring systems, which make use of guided wave ultrasound, can monitor long distances of rail track from a single transducer location.
  • Oxtoby, Oliver F (2012-07)
    We present an adaptively trained Reduced-Order Model (ROM) to dramatically speed up flow simulations of an oscillatory nature. Such repetitive flowfields are frequently encountered in fluid-structure interaction modelling, ...
  • Botha, Heila-Marie; Tkachuk, O; Van der Merwe, B; Visser, W (ACM Digital Library, 2017-07)
    Current dynamic analysis tools for Android applications do not get good code coverage since they can only explore a subset of the behaviors of the applications and do not have full control over the environment in which ...
  • Khan, ZC; Keet, CM (2013-09)
    An approach in achieving semantic interoperability among heterogeneous systems is to offer infrastructure to assist with linking and integration using a foundational ontology. Due to the creation of multiple foundational ...
  • Anochie-Boateng, Joseph; Komba, Julius J; Mvelase, GM (International Road Federation, 2011-11)
    The Council for Scientific and Industrial Research (CSIR) is undertaking a research project to investigate the use of laser-based scanning technology to quantify the morphological/shape properties (i.e., form - flatness, ...
  • Tsague, HD; Nelwamondo, F; Msimang, N (IEEE Xplore, 2012-11)
    One of the most commonly used two-factor user authentication mechanisms nowadays is based on smart card and personal identity number or password. A scheme of this type is usually known as, a smart card based password ...
  • Pancham, A; Tlale, N; Bright, G (2012-11)
    Simultaneous Localization And Mapping (SLAM) allows a mobile robot to construct a map of an unknown, static environment and simultaneously localize itself. Real world environments, however, have dynamic objects such as ...
  • Maritz, Johan; Le Roux, Alize; Van Huyssteen, E; Coetzee, M; Mans, Gerbrand G; Goss, H (CSIR, 2010-09)
    Over the last 5 years a set of incremental advances within geospatial analysis platforms and tools developed by the CSIR's Planning Support Systems in collaboration with key stakeholders such as The Presidency, enabled a ...
