Author:Nxumalo, S; Chikwanda, HK; Machio, Christopher NDate:Dec 2009The high temperature ß-TiPt phase has been shown to undergo a martensitic transformation upon quenching to room temperature. The martensitic transformation results from a transformation of the parent B2 cubic structure to the martensitic B19 ...Read more
Author:Matooane, M; Naidoo, R; Batterman, SDate:Aug 2010Exposure modelling in south Durban is constrained by a lack of population specific time-activity patterns data. We argue that the application of time-activity patterns from elsewhere in the world in exposure modelling in south Durban would ...Read more
Author:Nabarro, FRNDate:15 Jul 2001Under certain conditions, the plastic extension of a sample subjected to a constant stress is to a good approximation proportional to the logarithm of the time. Similarly, if a sample is plastically strained and unloaded, there are changes ...Read more
Author:Nel, Willem AJ; Giusti, E; Martorella, M; Abdul Gaffar, MYDate:Oct 2011Autofocus is a well known required step in ISAR (and SAR) processing to compensate translational motion. This research proposes a time domain autofocus algorithm and discusses its relation to the well known phase gradient autofocus (PGA) ...Read more
Author:Loveday, Philip W; Long, Craig SDate:Mar 2007Piezoelectric transducers are commonly used to excite waves in elastic waveguides such as pipes, rock bolts and rails. While it is possible to simulate the operation of these transducers attached to the waveguide, in the time domain, using ...Read more
Author:Bernhardi, EH; Forbes, A; Bollig, C; Esser, MJDDate:2008One of the main problems that limit the power scaling of diode-end-pumped solid-state lasers is the generation of heat inside the laser gain medium which can ultimately cause fracture. In this paper a time-dependent analytical thermal model ...Read more
Author:Malan, DFDate:Apr 1999Although hard rock is not usually associated with large creep deformation, significant time-dependent behaviour is observed in the tabular excavations of the South African gold mines. Time-dependent closure data was collected in stopes of the ...Read more
Author:Kabongo, GL; Mbule, PS; Mhlongo, Gugu H; Mothudi, BM; Dhlamini, MSDate:Jan 2020The fluorescence vibrational features of as-synthesized P3HT–ZnO:Ho3+ and P3HT–ZnO:Tm3+ thin films were investigated using Gaussian analysis. Relative to P3HT–ZnO:Tm3+ film, detailed Gaussian analysis of the fluorescence spectra revealed ...Read more
Author:Kanda, P; Burke, Michael G; Gupta, RDate:Sep 2018We analyse the dynamics of the causal interaction between the stock and foreign exchange markets for the United Kingdom using monthly data going as far back as 1791. First, we consider static causality tests, yielding mixed results. Given the ...Read more
Author:Bidwell, NJ; Reitmaier, T; Rey-Moreno, C; Roro, Z; Siya, MJ; Dlutu, BDate:Jul 2013Time is a key aspect of cross-cultural ICT4D research and practice, but rarely the focus of discussion. In this paper we, a group of researchers with diverse backgrounds and residences, aim to open up a dialogue about how different ...Read more
Author:Kebede, Mesfin ADate:Jun 2020Tin oxide, SnO2, is a suitable anode for both lithium-ion and sodium-ion batteries (LIBs and SIBs) unlike graphite and silicon, which are only suitable anodes for LIB. SnO2 has garnered much attention because of its high theoretical capacities ...Read more
Author:Cummings, F; Le Roux, Lukas J; Mutangwa, N; Knoesen, DDate:Oct 2009Vertically orientated titanium dioxide (TiO2) nanotubes hold great potential for application in dye-sensitized solar cells (DSCs) as they provide an unscathed, one-dimensional transport route for photo-generated charge carriers, thereby ...Read more
Author:Wright, Jarrad G; Calitz, Joanne RDate:Mar 2019This presentation discusses ways to avoid/mitigate loadshedding, as well as ways to keep the household running during periods of loadshedding.Read more
Author:Oosthuizen, SJDate:Oct 2010This paper examines innovation in relation to the availability of a new material, specifically the metal titanium. The paper aims to highlight the need for the inclusion of entrepreneurial innovation as a necessary focus area in the development ...Read more

Author:Crampton, Michael C; Berger, E; Louw, MEDate:Nov 2008Microbial cell surface display is the anchoring of a heterologous protein or peptide (passenger) to the outside of the cell wall as a fusion to a cell surface associated protein (carrier). This technology has been used extensively for both ...Read more
Author:Wall, K; Bhagwan, J; Ive, O; Kirwan, FDate:May 2012Studies have found that the concept of social franchising partnerships for the routine maintenance of infrastructure could alleviate and address many challenges in the management of water services. At the same time, these partnerships would ...Read more
Author:Meissner, RichardDate:Jan 2017Sustainable development is not a concept with one meaning only; it can also be infused iwth ambiguity, which should not be bemoaned. The concept's meaning is wide enough for all societal segments, from the individual to the largest entities, ...Read more
