Author:Cooper, Antony K; Schmitz, P; Krygsman, SCDate:Aug 2010During 2005, the CSIR ran a small experiment in the Pretoria area to test the feasibility of tracking passively cellular telephones, and hence people. Based on the success of that pilot, we initiated a large project to assess various aspects ...Read more
Author:Pancham, A; Withey, Daniel J; Bright, GDate:May 2015The tracking of moving points in image sequences requires unique features that can be easily distinguished. However, traditional feature descriptors are of high dimension, leading to larger storage requirement and slower computation. In this ...Read more
Author:Ajoodha, R; Rosman, Benjamin SDate:Nov 2017Current structure learning practices in Bayesian networks have been developed to learn the structure between observable variables and learning latent parameters independently. One exception establishes a variant of EM for learning the structure ...Read more
Author:Brits, ADate:Nov 2006There is a growing concern that performance in service delivery does not match the rate of progress required for poverty reduction. These concerns are focusing attention on the need for a better understanding of ‘planning and implementation ...Read more
Author:Napier, Mark; Berrisford, S; Wanjiku Kihato, C; McGaffin, R; Royston, LDate:Oct 2013This book provides an analytical perspective that is rigorously informed by detailed empirical work, and offers policy advice that is pragmatically grounded in the realities of governance and everyday urban life. Trading Places provides no ...Read more
Author:Johnson, D; Pejovic, V; Belding, E; Van Stam, GDate:Mar 2011While Internet connectivity has reached a significant part of the world’s population, those living in rural areas of the developing world are still largely disconnected. Recent efforts have provided Internet connectivity to a growing number ...Read more
Author:Komba, Julius J; Mataka, M; Malisa, JT; Walubita, LF; Maina, JWDate:Jul 2018Traffic loading is one of the key inputs for the structural design of pavements. For pavement design purposes, heavy vehicles are mostly used for the estimation of the traffic load spectra, as they cause the most structural damage to pavements. ...Read more
Author:Van Reenen, Coralie A; Du Plessis, CDate:Dec 2021Traffic noise transmission through the open windows of naturally-ventilated classrooms can reduce speech intelligibility and can negatively impact academic performance. The findings of a numerical study are presented. Software was used to ...Read more
Author:Senekal, FPDate:Nov 2008This paper presents a new technique for the recognition of road traffic signs. The technique is based on colour and shape analysis of a single image. It is aimed at the detection and classification of triangular traffic signs, such as warning ...Read more
Author:Makgatho, M; Marivate, V; Sefara, Tshephisho J; Wagner, VDate:Feb 2022How can we transfer semantic information between two low-resourced African languages? With one language having more resources than the other? The problem is that African languages still lag in the advances of Natural Language Processing ...Read more
Author:Badenhorst, J; Davel, MH; Barnard, EDate:Nov 2011The authors propose a piecewise-linear model for the temporal trajectories of Mel Frequency Cepstral Coefficients during phone transitions. As with conventional Hidden Markov Models, the parameters of the model can be estimated for different ...Read more
Author:Hiratsuka, M; Makondo, N; Rosman, Benjamin S; Hasegawa, ODate:Oct 2016This work proposes a framework that enables arbitrary robots with unknown kinematics models to imitate human demonstrations to acquire a skill, and reproduce it in real-time. The diversity of robots active in non-laboratory environments is ...Read more
