State of dispersion-distribution of the CNTs in the ...Read more
Author:John, Maya J; Jacob John, Maya; Jose, S; Varughese, KT; Thomas, SDate:2009This study explores the dynamic mechanical behavior of woven sisal fabric reinforced natural rubber composites. The influence of chemical modification on the viscoelastic properties has also been determined. Moreover, the effect of frequency ...Read more
Author:Al-Thabaiti, SA; Ray, SS; Basahel, SN; Mokhtar, MDate:Mar 2015This article reports the viscoelastic properties of poly[(butylene succinate)-co-adipate] (PBSA) nanocomposites. The nanocomposites of PBSA with various loadings of organically modified clay were prepared by melt-mixing in a batch-mixer. The ...Read more
Author:Napier, JAL; Malan, DFDate:Oct 1997A model is proposed for the direct mechanistic simulation of seismic activity and stress transfer effects in deep level mines. The model uses a discontinuum viscoplastic formulation to relate the rate of slip on a crack to the shear stress ...Read more
Author:Thabethe, S; Linganiso, E; Motaung, D; Mashapa, MG; Nkosi, S; Arendse, CJ; Mwakikunga, Bonex WDate:Nov 2013The procedures for the synthesis of amorphous e-FeSi/Si core–shell nanofibres by vapour transport in a CVD configuration are reported. Crystallite studies by the Williamson-Hall method show the sizes to be typically about 8.0 nm which agrees ...Read more
Author:Mukwevho, N; Kumar, Neeraj; Fosso-Kankeu, E; Waanders, F; Bunt, J; Ray, Suprakas SDate:Sep 2019In this study, ZnO/g-C(sub3)N(sub4) heterostructure was synthesized with enhanced photodegradation potential for polycyclic aromatic hydrocarbons (PAHs) (viz. naphthalene) in water using visible light. The as-prepared catalysts were characterized ...Read more
Author:Kanjee, R; Bachoo, AK; Carroll, JDate:Oct 2013Adaptive Cruise Control (ACC) is a relatively new system designed to assist automobile drivers in maintaining a safe following distance. This paper proposes and validates a vision-based ACC system which uses a single camera to obtain the ...Read more
Author:Sabatta, D; Siegwart, RDate:May 2013In this paper we present a vision-based path following algorithm for a non-holonomic wheeled platform capable of keeping the vehicle on a desired path using only a single camera. The algorithm is suitable for teach and replay or leader-follower ...Read more
Author:Sabatta, DGDate:Nov 2008This paper proposes a topological mapping technique that utilises persistent SIFT features to reduce the amount of data storage required. It delivers, as an output, a topological map that lends itself well to conventional path planning ...Read more
Author:De Saxe, Christopher CDate:Sep 2018Articulated Heavy Goods Vehicles (HGVs) are more efficient than conventional rigid lorries, but exhibit reduced low-speed manoeuvrability and high-speed stability. Technologies such as autonomous reversing and path-following trailer steering ...Read more
Author:Mthombeni, Thabo DMDate:Dec 2011VisTrails is an open-source scientific workflow and provenance management system that provides support for simulations, data exploration and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for ...Read more
Author:Matyila, M; Botha, Adèle; Alberts, R; Sibiya, GDate:May 2014Mobile services and mobile content is available to diverse users in possession of the necessary mobile phones. However, some of the mobile services and mobile content is text intensive and this discounts low literate users in participation ...Read more
Author:De Saxe, Christopher; Cebon, DDate:Nov 2016Application of articulated and Long Combination Vehicles (LCVs) in challenging off-highway applications is possible with the use of path-following trailer steering. This requires an accurate estimate of trailer off-tracking, but it has been ...Read more
Author:Smith, Andrew CDate:Feb 2009Good visual perception skills are important in the effective manipulation of Tangible User Interfaces. This paper reports on the application of a test set researchers have developed specifically to quantify the visual perception skills of ...Read more
Author:Burke, Michael GDate:Mar 2011This thesis presents work completed on the design of control and vision components for use in a monocular vision-based human-following robot. The use of vision in a controller feedback loop is referred to as vision-based or visual servo ...Read more
Author:Naidoo, T; Joubert, D; Chiwewe, T; Tyatyantsi, A; Rancati, B; Mbizeni, ADate:Mar 2014Road distresses, such as potholes and edge cracks, are not only a source of frustration to drivers but also negatively impact the economy due to damage to motor vehicles and costly road repairs. Regular and rapid pavement inspection and ...Read more
Author:Thomas, A; Gerber, AJ; Van der Merwe, ADate:Nov 2015Diagrams are often studied as visual languages with an abstract and a concrete syntax (concrete syntax is often referred to as visual syntax), where the latter contains the visual representations of the concepts in the former. A formal ...Read more
