  • Liang, Shen; He, Jun (2010-07)
    The performance of Evolutionary Programming (EP) is affected by many factors (e.g. mutation operators and selection strategies). Although the conventional approach with Gaussian mutation operator may be efficient, the ...
  • He, Jun; Kang, Lishan (2009-04-23)
    Multigrid methods have been proven to be an efficient approach in accelerating the convergence rate of numerical algorithms for solving partial differential equations. This paper investigates whether multigrid methods are ...
  • Zwiggelaar, Reyer; Parr, T. C.; Schumm, J. E.; Hutt, I. W.; Taylor, C. J.; Astley, S. M.; Boggis, C. R. M. (1999)
    Computer-aided mammographic prompting systems require the reliable detection of a variety of signs of cancer. In this paper we concentrate on the detection of spiculated lesions in mammograms. A spiculated lesion is typically ...
  • Snooke, Neal (2004-06)
    Failure Mode and Effects Analysis is widely used in engineering hardware systems to help in understanding the effects of potential failures and the faults that cause them to occur. The analysis is iterative leading to ...
  • Lee, Mark (2000)
    The software engineering industry suffers from almost unmanageable complexity both in the products it produces and in the processes of production. One of the current shortcomings in the software production process is the ...
  • Price, Chris; Struss, Peter (2004-01)
    The automotive industry was the first to promote the development of applications of model-based systems technology on a broad scale and, as a result, has produced some of the most advanced prototypes and products. In this ...
  • Shen, Qiang; Zhao, Ruiqing; Tang, Wansheng (2008-10)
    This short paper discusses the modeling of random fuzzy renewal reward processes in which the interarrival times and rewards are represented by nonnegative random fuzzy variables. Based on random fuzzy theory, a random ...
  • Dee, Hannah; Fraile, Roberto; Hogg, David C.; Cohn, Anthony G. (2008)
    This paper describes a method for building visual “maps” from video data using quantized descriptions of motion. This enables unsupervised classification of scene regions based upon the motion patterns observed within them. ...
  • Onyango, Christine M.; Marchant, John A.; Zwiggelaar, Reyer (1997-06)
    No absolute certainty can be given for information derived from images. In most cases image analysis uses single algorithms, or multiple single algorithms' results which are combined in an ad hoc manner, to derive certain ...
  • Rowland, Jeremy John (2003-11)
    The expressive power, powerful search capability, and the explicit nature of the resulting models make evolutionary methods very attractive for supervised learning applications in bioinformatics. However, their characteristics ...
  • Shen, Qiang; Rasmani, Khairul (2004)
    The use of fuzzy quantifiers in linguistic fuzzy models helps to build fuzzy systems that use linguistic terms in a more natural way. Although several fuzzy quantification techniques have been developed, the application ...
  • Schierz, Amanda (2007-11-01)
    The diffusion and transfer of knowledge is central to the process of innovation and is of importance to both academics and industrialists. In this paper, we propose that academic articles and patent documents referring to ...
  • Chen, Jingying; Tiddeman, Bernard Paul (Springer Berlin / Heidelberg, 2008-07-01)
    An efficient and robust facial feature detection and tracking system is presented in this paper. The system is capable of locating a human face automatically. Six facial feature points (pupils, nostrils and mouth corners) ...
  • Law, James; Johnson, Jeffrey (2008-06-30)
    Increasingly engineering involves systems with many autonomous subsystems and agents. Understanding and controlling such systems is beyond the abilities of traditional control methods. The issues are well captured by the ...
  • Shipman, Richard Charles (University of WalesComputer Science, 2011-09)
    Research at Aberystwyth into qualitative simulation of electrical circuits has been word-leading for nearly two decades. During that time, the Advanced Reasoning Group has developed a variety of electrical circuit ...
  • Hülse, Martin; McBride, Sebastian; Lee, Mark (2011-04)
    This work introduces an architecture for a robotic active vision system equipped with a manipulator that is able to integrate visual and non-visual (tactile) sensorimotor experiences. Inspired by the human vision system, ...
  • Doerr, Benjamin; Jansen, Thomas; Sudholt, Dirk; Winzen, Carola; Zarges, Christine (2013)
    Extending previous analyses on function classes like linear functions, we analyze how the simple (1+1) evolutionary algorithm optimizes pseudo-Boolean functions that are strictly monotonic. These functions have the property ...
  • Hogg, David C.; Dee, Hannah (2006)
    This paper will describe new work that attempts to perform the modelling of human behaviour not at the level of visible patterns of motion, but at the level of intentions. By inferring intentions in terms of known goals, ...
  • Dee, Hannah Mary; Hogg, David C. (2009-02-01)
    We propose a new method that treats visible human behaviour at the level of navigational strategies. By inferring intentions in terms of known goals, it is possible to explain the behaviour of people moving around within ...
