Author:Makondo, Ndivhuwo; Hiratsuka, M; Rosman, Benjamin S; Hasegawa, ODate:Apr 2018The number and variety of robots active in real-world environments are growing, as well as the skills they are expected to acquire, and to this end we present an approach for non-robotics-expert users to be able to easily teach a skill to a ...Read more
Author:Uhrich, P; Castrignano, S; Uys, Hermann; Kastner, MDate:Aug 2017The measurement of dynamic correlation functions of quantum systems is complicated by measurement backaction. To facilitate such measurements we introduce a protocol, based on weak ancilla-system couplings, that is applicable to arbitrary ...Read more
Author:Anandjiwala, RD; Gonsalves, JWDate:2005In this paper the fabric buckling model proposed by Grosberg and Swani has been modified by incorporating Huang’s bending rule. The proposed model is an extension of the present model and also covers the special cases. The numerical results ...Read more
Author:Zongo, S; Sanusi, K; Britton, J; Mthunzi-Kufa, Patience; Nyokong, T; Maaza, M; Sahraoui, BDate:Aug 2015We have investigated the nonlinear optical properties, including the optical limiting behaviour for five different concentrations of laccaic acid dye in solution and a thin film obtained through doping in poly (methyl methacrylate) (PMMA) ...Read more
Author:Waterhouse, JS; Switsur, VR; Barker, AC; Carter, AHC; Hemming, DL; Loader, NJ; Robertson, IDate:Apr 2004In order to predict accurately how elevated atmospheric CO2 concentrations will affect the global carbon cycle, it is necessary to know how trees respond to increasing CO2 concentrations. In this paper, the response is examined over the period ...Read more
Author:Van Wyk, BJ; Van Wyk, MA; Van Den Bergh, FDate:Jun 2007The concept of an Image Difference Spectrum, a novel tool for the extraction of global image information, is introduced. It is shown that Image Difference Spectra are fast alternatives to granulometric curves, also referred to as pattern ...Read more
Author:Horak, RM; Learmonth, RA; Maharaj, VJDate:27 Feb 1995The preparation of 2-[2H]-l-(p-nitrophenyl)-1,2-epoxyheptan-3-one and its subsequent reduction by baker's yeast to the 2,3-diol is described. The mechanism of the reduction of the epoxide was determined using the B-2H isotope shift in 3C ...Read more
Author:Thakur, A; Moyo, P; Van Der Westhuizen, Carl Johan; Yang, HO; Maharaj, VDate:Jul 2021Elevated levels of the amylo ß-proteins (Aß), particularly Aß42, are associated with a high risk of Alzheimer's disease (AD). The Aß proteins are produced from cellular processing of the amyloid precursor proteins (APPs). To identify natural ...Read more
Author:Schenker, R; De Beer, DJ; Du Preez, WB; Thomas, ME; Richter, PWDate:Aug 1999The technologies of reverse engineering and rapid prototyping are emerging as useful new tools in medicine. One application is of particular interest in orthopaedic, dental and reconstructive surgery. It involves the imaging, modelling and ...Read more
Author:Adetunji, KE; Hofsajer, IW; Abu-Mahfouz, Adnan MI; Cheng, LDate:Nov 2022Achieving a sustainable and efficient power systems network and decarbonized environment involves the optimal allocation of multiple distributed energy resource (DERs) unit types and flexible alternating current transmission systems (FACTS) ...Read more
Author:Nicolaides, CPDate:1999Hydrogels, typically used for the synthesis of highly crystalline ZSM-5 samples at 150 degrees C and under autogenous pressure, were subjected to lower hydrothermal synthesis temperatures, i.e., from 25 degrees C to 130 degrees C. XRD analysis ...Read more
Author:Msiza, IS; Malumedzha, TC; Leke-Betechuoh, BDate:Aug 2011Fingerprint re-alignment is an important aspect in the subject of fingerprint biometrics because a fingerprint recognition system that does not attempt to re-align an involuntarily rotated fingerprint can create opportunities for falsely ...Read more
Author:Parmaliana, A; Frusteri, F; Mezzapica, A; Scurrell, MS; Giordano, NDate:07 May 1993Vanadium oxide-silica catalysts can effect the partial oxidation of methane to formaldehyde with extremely high activities and the space time yield (STY) can reach a value in excess of 800 g kg-1cat h-1; bare silica also shows appreciable STY ...Read more
Author:Veldman, CSDate:2003An implementation of the sine-approximation method of ISO 16063-11 (primary vibration calibration by laser interferometry) is described. The quadrature interference signals are generated using an interferometer as described in method 3 of ISO ...Read more
