Author:Croucamp, PL; Rimer, S; Kruger, Carel PDate:Jul 2014Theft of cables used for powering a locomotive not only stops the train from functioning but also paralyzes the signalling and monitoring system. This means that information on certain locomotive's cannot be passed onto other locomotives which ...Read more
Author:Rens, G; Lakemeyer, G; Meyer, TDate:Aug 2012We propose a non-standard modal logic for specifying agent domains where the agent’s actuators and sensors are noisy, causing uncertainty in action and perception. The logic is multi-modal, indexed with actions; the logic is also augmented ...Read more
Author:Rens, G; Meyer, T; Ferrein, A; Lakemeyer, GDate:Jul 2011The authors propose a novel modal logic for specifying agent domains where the agent’s actuators and sensors are noisy, causing uncertainty in action and perception. The logic draws both on POMDP theory and logics of action and change. The ...Read more
Author:Rens, G; Meyer, T; Lakemeyer, GDate:Mar 2014We present a logic inspired by partially observable Markov decision process (POMDP) theory for specifying agent domains where the agent's actuators and sensors are noisy (causing uncertainty). The language features modalities for actions and ...Read more

Author:Steenkamp, Karen C; Wessels, Konrad J; Archibald, S; Von Maltitz, Graham PDate:Nov 2008Satellite-derived phenology allows monitoring of terrestrial vegetation on a global scale and provides an integrative view at the landscape level. Understanding these seasonal phenological patterns is essential to (i) the characterisation and ...Read more
Author:Keaikitse, M; Brink, W; Govender, NatashaDate:Nov 2014Detection and tracking are important components of many computer vision applications including automated surveillance. Object detection should overcome challenges such as changes in object appearances, illumination, and shadows. In our system, ...Read more
Author:Engelbrecht, Jeanine; Inggs, MRDate:Aug 2016Differential radar interferometry (dInSAR) techniques are well known for their ability to provide mm- to cm-scale measurements of surface deformation. Very accurate measurements of deformation have been achieved in several areas of research ...Read more
