Active object recognition using vocabulary trees

Author: Govender, Nicolin ; Claassens, J ; Nicolls, F ; Warrell, J Date: Jan 2013 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 classification. This paper ... Read more
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
Climate and the inter-annual variability of fire in southern Africa: a meta-analysis using long-term field data and satellite-derived burnt area data

Author: Archibald, S ; Nickless, A ; Govender, Nicolin ; Scholes, RJ ; Lehsten, V Date: Nov 2010 This study investigates inter-annual variability in burnt area in southern Africa and the extent to which climate is responsible for this variation. We compare data from long-term field sites across the region with remotely sensed burnt area ... 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 ...

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 ...

Fundamental frequency and tone in isiZulu: initial experiments

Author: Govender, Nicolin ; Barnard, E ; Davel, MH Date: Sep 2005 Much theoretical work has been done on the tonal structure of languages in the Bantu family. However, most of these studies are not supported by physical measurements, or even a consistent model for mapping from linguistic constructs to such ... Read more
GPU-based discrete element rigid body transport

Author: Govender, Nicolin ; Gledhill, Irvy MA ; Kok, S ; Wilke, N Date: Aug 2013 The protection of harbours and coastal infrastructure is of vital importance to South Africa. A major development in the design of packing strategies for breakwaters is numerical modelling, and the use of physics engines and DEM models. For ... 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
