Author:Schwegmann, CP; Kleynhans, W; Salmon, BPDate:Jul 2014Synthetic Aperture Radar images are able to detect ships that would be hidden to tradition ship tracking methods due to their transponders being turned off. Using a SAR image as input, the CFAR method can highlight these ships given a correctly ...Read more
Author:Musee, NDate:Sep 2011This paper attempts to quantify the potential risks posed by engineered nanomaterials (ENMs) to the aquatic and terrestrial ecosystems from cosmetic-based nanoproducts. The predicted environmental concentrations (PEC) were modelled for the ...Read more
Author:Burger, L; Litvin, IA; Forbes, ADate:Apr 2008Demonstration of the effect of atmospheric turbulence on the propagation of laser beams is traditionally a difficult task. This is due to the complexities of long-distance measurements and the scarcity of suitable laser wavelengths in atmospheric ...Read more
Author:Bopape, Mary-Jane M; Engelbecht, F; Randall, DDate:Oct 2012As part of ongoing model development work being done at the CSIR, a model that
can be used to study thunderstorms has been developed. In this case we are showing its application over the Western Pacific ocean
in the tropics where observation ...Read more
Author:Bopape, Mary-Jane M; Engelbrecht, F; Randall, D; Landman, WDate:Sep 2012Cloud Resolving Models (CRMs) employ microphysics parameterisations which are grouped into bin and bulk approaches. Bulk Microphysics Parameterisation (BMP) schemes specify a functional form for the particle distribution and predict one or ...Read more
Author:Van Eden, Beatrice; Botha, NatashaDate:Nov 2023Collaborative robots are adopted in the drive towards Industry 4.0 to automate manufacturing, while retaining a human workforce.

Author:Zhang, Y; Mclaren, M; Roux, FS; Forbes, ADate:Jul 2014We present a simple method of simulating the effect of the pumping process in spontaneous parametric down-conversion (SPDC) by modulating a classical laser beam with two spatial light modulators through a back projection setup. We simulate a ...Read more
Author:Zhang, Y; McLaren, M; Roux, FS; Forbes, ADate:Aug 2014We present a simple way of simulating Spontaneous parametric down-conversion (SPDC) by modulating a classical laser beam with two spatial light modulators (SLM) through a back projection setup. This system has the advantage of having very ...Read more
Author:Bopape, Mary-Jane M; Engelbrecht, FA; Randall, DA; Landman, WADate:Sep 2013The two-dimensional Non-hydrostatic s-coordinate Model (NSM) is used to simulate two twelve day periods and an eight day period observed during the Tropical Oceans Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (TOGA COARE). ...Read more
Author:Willers, Cornelius J; Willers, MSDate:Nov 2012The paper presents a description of an image-based simulation system, the Optronic System Simulator (OSSIM). OSSIM provides the ability to model the individual components in detail, but also accurately models the interaction between the ...Read more
