Author:Curtayne, PC; Walker, RNDate:26 Jan 2009The need for describing the condition of pavements occurs frequently in highway engineering. Accurate descriptions are a prerequisite for establishing procedures with which to evaluate the various aspects of the pavement condition. A variety ...Read more
Author:Naidoo, Shahen; Le Roux, WHDate:Jul 2007The emergence of numerous command and control (C2) systems and simulators necessitate the standardisation of interfaces and the definition of scenarios to facilitate their efficient co-existence. This paper comments on the activities of the ...Read more
Author:Dube, S; Davhana, MDate:Jul 2015South Africa’s road safety rate ranks fourth worst in the world, however very little is done to correct the existing problem. Currently in South Africa and in the other parts of the continent and the world, only limited statistics are available ...Read more
Author:Simpson, BRS; Morris, WMDate:Feb 2004The activity of the pure beta-emitter phosphorus-33 (P-33) has been directly determined by the triple-to-double coincidence ratio (TDCR) efficiency calculation technique, thus extending the number of radionuclides that have been standardized ...Read more
Author:Cooper, Antony KDate:Jun 1993The purpose of this dissertation is to assess digital geo-referenced information and standards for exchanging such information, especially the South African National Exchange Standard (NES). The process of setting up a standard is exacting. ...Read more

Author:Marais, Laurette; Van Zijl, LDate:Sep 2018Given two unary languages accepted by symmetric difference non-deterministic finite automata, we establish bounds on the state complexity of their union, intersection, relative complement and symmetric difference. For languages L1 and L2 ...Read more
Author:Marais, Laurette; Van Zijl, LynetteDate:Jul 2017Unary self-verifying symmetric difference automata were introduced in [1], with an upper bound of O(2(supn) ) and lower bound of 2(sup n-1) -1 for state complexity. Implicit in the interpretation of self-verifying acceptance for the symmetric ...Read more
Author:Duvenhage, A; Le Roux, WHDate:2007The increased use of simulations during live air defense exercises requires interoperability between different Command and Control (C2) systems and simulators. By accepting air picture or sensor tracks from each other, C2 systems and simulators ...Read more
Author:Lubbe, Estelle; Withey, Daniel J; Uren, KRDate:Sep 2015This paper introduces a state estimation methodology for a hexapod robot that makes use of proprioceptive sensors and a kinematic model of the robot. The methodology focuses on providing reliable full pose state estimation for a commerciall ...Read more
Author:Tshehla, KS; Hamam, Y; Abu-Mahfouz, Adnan MIDate:Nov 2017Monitoring of a Water Distribution Network (WDN) requires information about the present state of the network. Since all variables are usually not measurable directly, State estimation is employed. State estimation is a process of determining ...Read more
Author:Dlodlo, N; Foko, Thato E; Mvelase, P; Mathaba, SDate:Jun 2012With the internet of things (IoT) being a new research area, the work that is going on in this field worldwide is disjoint. The picture is not clear on who is doing what and where, thereby making it difficult not only for newcomers into this ...Read more
