BLAZE-DEM: A GPU based Polyhedral DEM particle transport code

Author: Govender, Nicolin Date: May 2013 This paper introduces the BLAZE-DEM code that is based on the Discrete Element Method (DEM) and specifically targeted for Graphical Processing Unit (GPU) platforms. BLAZE-DEM uses actual polyhedral particle representations as opposed to ... Read more
Collision detection of convex polyhedra on the NVIDIA GPU architecture for the discrete element method

Author: Govender, Nicolin ; Wilke, DN ; Kok, S Date: Sep 2015 Convex polyhedra represent granular media well. This geometric representation may be critical in obtaining realistic simulations of many industrial processes using the discrete element method (DEM). However detecting collisions between the ...

Comparison of image sharpness metrics and real-time sharpening methods with GPU implementations

Author: De Villiers, Johan P Date: Jun 2010 Improving the quality of an image increases the probability, speed and accuracy with which possible objects of interest can be located and identified. Image sharpening, in particular, can correct for soft focus and strengthen the outlines of ... Read more
Development of a convex polyhedral discrete element simulation framework for NVIDIA Kepler based GPUs

Author: Govender, Nicolin ; Wilke, DN ; Kok, S ; Els, R Date: 2013 Understanding the dynamical behavior of Granular Media (GM) is extremely important to many industrial processes. Thus simulating the dynamics of GMis critical in the design and optimization of such processes. However, the dynamics of GM is ... Read more
Discrete element simulation of mill charge in 3D using the BLAZE-DEM GPU framework

Author: Govender, Nicolin ; Rajamani, RK ; Kok, S ; Wilke, DN Date: Aug 2015 The Discrete Element Method (DEM) simulation of charge motion in ball, semi autogenous (SAG) and autogenous mills has advanced to a stage where the effects of lifter design, power draft and product size can be evaluated with sufficient accuracy ...

Improved real-time photogrammetric stitching

Author: De Villiers, J ; Cronje, J Date: Apr 2013 This work extends earlier work on the real-time photogrammetric stitching of staring arrays of high resolution videos on commercial off the shelf hardware. The blending is both further optimised for Graphics Processor Unit (GPU) implementation ... Read more
Permanent national test bed for passive radar testing and qualification

Author: Sendall, Joshua L ; Lysko, Albert A ; Maasdorp, Francois DV ; Tong, Craig A ; Cilliers, Jacques E Date: Nov 2018 This paper overviews the current development state of a permanent test bed for passive radar. The computational challenges of developing a permanent multistatic passive radar test bed are discussed, and the effects of implementing sparse ... Read more
Real-time exposure fusion on a mobile computer

Author: Bachoo, AK Date: Dec 2009 Within the context of video surveillance, object and incident detection by an operator is minimized in over- and under-exposed pixels. Multiple different exposures of the same scene can be fused to create a well-balanced and detailed image ... Read more
Validation of the GPU based BLAZE-DEM framework for hopper discharge

Author: Govender, Nicolin ; Pizette, P ; Wilke, DN ; Abriak, N Date: Sep 2015 Understanding the dynamical behavior of particulate materials is extremely important to many industrial processes, with typical applications that range from hopper flows in agriculture to tumbling mills in the mining industry. The discrete ... Read more
