    • Revitalizing An Aging Field-Tinggi Production Decline Mitigation 

      Kabir, AH; Othman, M; Talib, M; Hitam, S; Janor, M; Osman, A; Yunos, A (One Petro, 1999-10)
      Abnormal production decline causes concerns like high operating cost, premature field abandonment resulting in reserves loss and staff demoralisation, all of which have an adverse effect on an E&P company. Operational ...
    • Operative diagnosis algorithms for single-fault in graph-based systems 

      Elhadef, Mourad; El Ayeb, Bechir; SV Rao, Nageswara (Springer, Berlin, Heidelberg, 2000-06)
      A number of real-life systems can be modeled, to a certain level of abstraction, as directed graphs for the purpose of fault diagnosis. In these graphs, system components are represented as nodes and the fault propagation ...
    • An evolutionary algorithm for identifying faults in t-diagnosable systems 

      Elhadef, Mourad; Ayeb, Béchir (IEEE, 2000-10)
      The paper describes a novel approach to the problem of system-level fault diagnosis using genetic algorithms. Consider a system composed of n independent units, each of which tests a subset of the others. It is assumed ...

    • Adaptive mutation for semi-separable problems 

      Elhadef, Mourad; A Coley, David (ACM, 2001-07)
      In this paper we introduce a new mutation heuristic in an attempt to better match genetic algorithms and the geography of search spaces. This is achieved by varying the mutation rate across the genotype to more rapidly ...
    • An evolutionary algorithm for generalized comparison-based self-diagnosis of multiprocessor systems 

      Elhadef, Mourad; Ayeb, Béchir (Taylor & Francis Group, 2002-01)
      In this article, we consider the problem of self-diagnosis of multiprocessor and multicomputer systems under the generalized comparison model. In this approach, a system consists of a collection n independent heterogeneous ...
    • Vibrational Properties of Two Isolated Steps: A Theoretical Model 

      O Rafil; A Lalaoui; M Tamine; A Khelifi (World Scientific Publishing Company, 2002-01)
      We investigate the dynamical properties of two isolated steps on the surface. We present the solution of the full dynamical problem arising from the absence of translation symmetry in two dimensions due to extended surface ...

    • Design radius requirements for simple horizontal curves on three-dimensional alignments 

      Easa, Said M; Dabbour, Essam (NRC Research Press, 2003)
      : Current North American design guides have established mathematical relationships to calculate the minimum radius required for horizontal curves as a function of design speed, maximum superelevation, and maximum side fric- ...
    • Consolidating the ISO usability models 

      Abran, Alain; Khelifi, Adel; Suryn, Witold; Seffah, Ahmed (Research Gate, 2003-04)
      In recent years, the usability of software has become a major research theme within the software engineering community. However, only a few software quality models have been designed to address usability aspects in a ...
    • Towards Automatic Device Configuration in Smart Environments 

      Connelly, Kay; Khalil, Ashraf (Citeseer, 2003-10)
      As the number of mobile devices we carry grows, the job of managing those devices throughout the day becomes cumbersome. In addition, the ability to use mobile devices in unethical ways without being detected is becoming ...
    • Usability meanings and interpretations in ISO standards 

      Abran, Alain; Khelifi, Adel; Suryn, Witold; Seffah, Ahmed (Kluwer Academic Publishers, 2003-11)
      The usability of a software product has recently become a key software quality factor. The International Organization for Standardization (ISO) has developed a variety of models to specify and measure software usability ...
    • Three-Dimensional Model for Stop-Control Intersection Sight Distance 

      Easa, Said M; Dabbour, Essam; Ali, Muhammad Z. A. (American Society of Civil Engineers, 2004)
      Intersection sight distance (ISD) is the sight distance to be provided at intersections between a minor road and a major road. Current AASHTO policy provides an equation and charts for the required at-grade ISD so that a ...
