Research ArticleOpen accessIn the abstractRadiometric Correction of Multitemporal Satellite ImagerySeema Gore Biday, Udhav BhosleProblem statement: Repeated observation of a given area over time yields potential for many forms of change detection analysis. These repeated observations are confounded in terms of radiometric consistency due to changes in sensor calibration over time, differences in illumination, observation angles and variation in atmospheric effects. Also major problem with satellite images is that regions below clouds are not … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Backward Recovery Mechanism in Preemptive Utility Accrual Real Time Scheduling AlgorithmIdawaty Ahmad, Muhammad Fauzan OthmanProblem statement: This study proposed a robust algorithm named as Backward Recovery Preemptive Utility Accrual Scheduling (BRPUAS) algorithm that implements the Backward Recovery (BR) mechanism as a fault recovery solution under the existing utility accrual scheduling environment. The problem identified in the TUF/UA scheduling domain is that the existing algorithms only considers the Abortion Recovery (AR) as their fault recovery … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorting N-Elements Using Natural Order: A New Adaptive Sorting ApproachShamim Akhter, M. Tanveer HasanProblem statement: Researchers focused their attention on optimally adaptive sorting algorithm and illustrated a need to develop tools for constructing adaptive algorithms for large classes of measures. In adaptive sorting algorithm the run time for n input data smoothly varies from O(n) to O(nlogn), with respect to several measures of disorder. Questions were raised whether any approach or technique would … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,730 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Utility Accrual Scheduling Algorithms for Adaptive Real Time SystemIdawaty Ahmad, Muhammad Fauzan OthmanProblem statement: This study proposed two utility accrual real time scheduling algorithms named as Preemptive Utility Accrual Scheduling (PUAS) and Non-preemptive Utility Accrual Scheduling (NUAS) algorithms. These algorithms addressed the unnecessary abortion problem that was identified in the existing algorithm known as General Utility Scheduling (GUS). It is observed that GUS is inefficient for independent task model because it simply … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,356 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Peak Load Electricity Demand Using Statistics and Rule Based ApproachZ. Ismail, A. Yahya, K. A. MahpolProblem statement: Forecasting of electricity load demand is an essential activity and an important function in power system planning and development. It is a prerequisite to power system expansion planning as the world of electricity is dominated by substantial lead times between decision making and its implementation. The importance of demand forecasting needs to be emphasized at all level as … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractRepresentation of Polygonal Surfaces as Displaced Subdivision SurfacesMuhammad HussainProblem statement: Displaced subdivision representation possesses a number of attractive features for efficient and convenient processing tasks like editing, geometry compression, animation, scalability and adaptive rendering of polygonal models. In this representation, a detailed surface model was built as a scalar-valued displacement map over a smooth domain surface. The construction of the smooth domain surface from a polygonal model was … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 6,857 accessesView PDFCite
