Author:Majozi, T; Stamp, JDate:Oct 2010The use of heat integration in multipurpose batch plants to minimise energy usage has been in the literature for more than two decades. Direct heat integration may be exploited when the heat source and heat sink processes are active over a ...Read more
Author:Lysko, Albert ADate:Jun 2009The paper introduces a method to cover several wire segments with a single basis function, describes related practical algorithms, and gives some results. The process involves three steps: identifying chains of wire segments, splitting the ...Read more
Author:Joubert, SV; Fedotov, I; Pretorius, W; Shatalov, MYDate:May 2007“Bryan’s effect" - that is, the effect of a vibrating pattern’s precession in the direction of inertial rotation of a vibrating ring - was discovered by G. Bryan in 1890. This effect has several applications in navigational instruments, such ...Read more
Author:Namoshe, M; Tlale, NS; Kumile, CMDate:Jul 2008Open source software simulators play a major role in robotics design and research as platforms for developing, testing and improving architectures, concepts and algorithms for cooperative/multi-robot systems. Simulation environment enables ...Read more
Author:Berglund, Martin; Drewes, F; Van der Merwe, BDate:Aug 2018Modern regular expression matching software features many extensions, some general while some are very narrowly specified. Here we consider the generalization of adding a class of operators which can be described by, e.g. finite-state ...Read more
Author:Butgereit, L; Martinus, Laura JBDate:Aug 2018Tourism is a major contributor to employment in southern Africa and a major contributor to gross domestic products of many southern African countries. One of the major tourist attractions in many southern African countries is the wild animals. ...Read more
Author:Rens, GDate:Apr 2016I propose a framework for an agent to change its probabilistic beliefs when a new piece of propositional information a is observed. Traditionally, belief change occurs by either a revision process or by an update process, depending on whether ...Read more
Author:Cilliers, Jacques E; Smit, JCDate:Oct 2007In [1] the authors introduced a technique for generating mismatched pulse compression filters for linear frequency chirp signals. The technique minimizes the sum of the pulse compression sidelobes in a p L –norm sense. It was shown that ...Read more
Author:Booth, R; Casini, G; Meyer, T; Varzinczak, IDate:Jul 2015Propositional Typicality Logic (PTL) is a recently proposed logic, obtained by enriching classical propositional logic with a typicality operator. In spite of the non-monotonic features introduced by the semantics adopted for the typicality ...Read more
Author:Cooper, Antony K; Coetzee, SerenaDate:Apr 2020Publicly-available mobile data can be used to derive fine grain commuting and travel patterns. These types of data include geocoded or geotagged discrete units of communication: messages, posts, tweets, status updates, check-ins, images and ...Read more
Author:Rens, G; Meyer, T; Lakemeyer, GDate:May 2013We investigate the requirements for specifying the behaviors of actions in a stochastic domain. That is, we propose how to write sentences in a logical language to capture a model of probabilistic transitions due to the execution of actions ...Read more
Author:Grobler, M; Swart, IDate:Jul 2014Cyber warfare is a contentious topic, with no agreement on whether this is a real possibility or an unrealistic extension of the physical battlefield. This article will not debate the validity and legality of the concept of cyber warfare, but ...Read more
Author:Shatalov, M; Manzhirov, A; Fedotov, IDate:Sep 2012The theory of accreting structures is a new and fast developing branch of analytical mechanics basing on the theory of partial differential and integral equations. In the present paper the authors analyze qualitative properties of accreting ...Read more
Author:Varzinczak, JJDate:Jul 2009Domain descriptions in reasoning about actions are logical theories and as such they may also evolve. Given that, knowledge engineers also need revision tools to incorporate new incoming laws about the dynamic environment. Here the authors ...Read more
Author:Cilliers, Jacques E; Smit, JCDate:Sep 2009In previous paper the authors introduced a technique for generating mismatched pulse compression filters for linear frequency chirp signals. The technique minimizes the sum of the pulse compression sidelobes in an Lp norm sense. It was shown ...Read more
Author:Bencherif, H; Begue, NM; Diab, CR; Sivakumar, V; Keckhut, PDate:Sep 2010The present reports on the use of a multi-regression model adapted at Reunion University for temperature and ozone trend estimates. Depending on the location of the observing site, the studied geophysical signal is broken down in form of a ...Read more
Author:Meijer, M-C; Dala, LDate:Jun 2015The basis of linear piston theory in unsteady potential flow is used in this work to develop a quantitative treatment of the validity range of piston theory. In the limit of steady flow, velocity perturbations from Donov’s series expansion ...Read more
Author:Rosman, Benjamin S; Ramamoorthy, S; Mahmud, MMH; Kohli, PDate:Feb 2014Different interfaces allow a user to achieve the same end goal through different action sequences, e.g., command lines vs. drop down menus. Interface efficiency can be described in terms of a cost incurred, e.g., time taken, by the user in ...Read more
Author:Sahraeian, R; Van Compernolle, D; De Wet, FebeDate:May 2014This paper demonstrates the application of Intrinsic Spectral Analysis (ISA) for low-resource Automatic Speech Recognition (ASR).
