Author:Grobler, AJ; Holm, SR; Van Schoor, GDate:Nov 2015(PMSMs) are well suited for high-speed (HS) applications due to their high efficiency, power density, and dynamic response capability. The heat extraction area decreases as the speed increases, making thermal effects more dominant at high ...Read more
Author:Shou, KJ; Napier, JALDate:Sep 1999A new displacement discontinuity method is developed for the analysis of multi-layered elastic media. This approach is based on a novel superposition scheme and the analytical solution to the problem of a displacement discontinuity element ...Read more
Author:Smit GJF; Wilms JM; Diedericks GPJDate:Nov 2010Models that are used for the simulation of two-phase flows in coastal dynamics make extensive use of empirical data. The main focus of this investigation is to develop models for specific aspects of two-phase flows that are based on physical ...Read more
Author:Nabarro, FRNDate:Sep 2000The structure and properties of two families of lattice-coherent composites, those based on gamma' Ni3Al and those based on TiA/Ti3Al, are shown to have strong similarities. The coherent system of cubic/tetragonal Y2O3-stabilized ZrO2 is ...Read more
Author:McLaren, M; Romero, J; Padgett, MJ; Roux, FS; Forbes, ADate:Sep 2013In this paper we consider geometrical two-photon optics of Bessel-Gaussian modes generated in spontaneous parametric down-conversion of a Gaussian pump beam. We provide a general theoretical expression for the orbital angular momentum (OAM) ...Read more
Author:Stewart, TJ; Ittmann, HWDate:1979A study of the economic distribution of maize throughout South Africa is reported. Although the problem of minimizing total transportation costs in such a situation is a classical one, and its solution is well known, there was in this case a ...Read more
Author:Fernandes, PJLDate:Mar 1998This article discusses the outcome of an investigation of the failure of copper tubes from cold water distribution system carrying potable water in a shopping centre. Samples of copper tubes from a cold water distribution system which had ...Read more
Author:De Beer, Morris; Sadzik, EM; Fisher, C; Coetzee, CHDate:Jul 2005This paper addresses the measurement (i.e. “fingerprinting”) of tyre loading and contact stress patterns associated with slow moving test tyres on the new Heavy Vehicle Simulator (HVS Mk IV+) of Gautrans. The two test tyres used on the HVS ...Read more
Author:De Beer, Morris; Fisher, C; Kannemeyer, LDate:Sep 2004The aim of this paper is to highlight the use of SIM (Stress-In-Motion) technology on typical heavy vehicles found at the N3-TCC (Traffic Control Centre), with illustrative examples on real world trucks on this highway. A summary of the ...Read more
Author:Mufhandu, Hazel T; Alexandre, Kabamba B; Gray, ES; Morris, L; Khati, MDate:Sep 2016We have previously shown that the aptamer, UCLA1, is able to inhibit HIV-1 replication in peripheral blood mononuclear cells (PBMCs) by binding to residues in gp120. In this study we examined whether UCLA1 was effective against HIV-1 subtype ...Read more
Author:Perrie, BD; Strauss, PJ; Du Plessis, LDate:Aug 2007Ultra thin continuously reinforced concrete pavements (UTCRCP), in literature also referred to as Ultra Thin Reinforced High Performance Concrete (UTHRHPC), have been used in Europe successfully as a rehabilitation measure on steel bridge ...Read more
Author:Du Plessis, L; Kilian, A; Mngaza, KDate:Jul 2014The design and use of ultra-thin reinforced concrete pavements (UTRCP) are well known and are implemented successfully in residential streets and low-volume roads. Various publications are available to assist engineers and contractors to ...Read more
Author:Shingange, Katekani; Swart, H; Mhlongo, Gugu HDate:Nov 2019Herein, we report on one-dimensional porous Au-modified LaFeO3 nanobelts (NBs) with high surface area, which were synthesized through the electrospinning method. The incorporation and coverage of Au nanoparticles (NPs) on the surface of the ...Read more
