Author:Van de Steen, B; Vervoort, A; Napier, JAL; Durrheim, RJDate:Apr 2003This paper investigates whether a micromechanical model developed to investigate the relation between the basic failure processes at grain-scale and the macroscopic failure pattern can be applied to model the fracturing around large-scale ...Read more
Author:Mathumo, TW; Swart, TG; Focke, Richard WDate:Sep 2017The use of GNU Radio in order to explore FMCW radar is growing rapidly, where it is used for radar signal processing. In this paper we implement FMCW surveillance radar for drone detection on SDR using GNU Radio and the USRP B210. The requirement ...Read more
Author:Bogaers, Alfred EJ; Jansen van Rensburg, GJ; Marquart, R; Skatulla, SDate:Sep 2018In this paper, we outline the implementation of Hibler’s visco-plastic (VP) sea ice model into OpenFOAM, an opensource finite-volume modelling toolkit. Hibler’s visco-plastic model is arguably the most widely used description of sea ice ...Read more
