Research ArticleOpen accessIn the abstractAdaptive Acceptance Criterion (AAC) Algorithm for Optimization ProblemsAnmar AbuhamdahOptimization methods commonly are designed for solving the optimization problems. Local search algorithms are optimization method, which are good candidate in exploiting the search space. However, most of them need parameter tuning and incapable of escaping from local optima. This work proposes non-parametric Acceptance Criterion (AC) that not relies on user-defined, which motivate to propose an Adaptive Acceptance Criterion (AAC). … …Journal of Computer Science, Vol. 11, Issue 4 · 23 Jul 2015 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Evaluation of Coulomb Lattice Sums of Charge SystemsV. Ilyin, A. Brandt, I. SuwanProblem statement: Due to the long range nature of interactions of the N-body systems, direct computation of the Coulomb potential energy involves O(N2) operations. To decrease such complexity, a simple Multilevel Summation method has been developed. Approach: In the frame of the Multilevel Summation method, the two-body interaction is decomposed into two parts: a local part and a smooth part. … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 11 Sep 2012 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractEast Kolkata Wetland: A Multifunctional Niche of International ImportanceI. Mukherjee, S. Ray Chaudhuri, D. Ghosh, A. R. ThakurProblem statement: In the megacity Kolkata, the need for space to accomodate the ever increasing population is increasing day by day. As a result the encoarchment of the large wetland on the eastern frindge of the city is increasing and so is the threat of its loosing the status of Ramsar Status. Approach: Proper documentation of the existing traditional practice … …OnLine Journal of Biological Sciences, Vol. 12, Issue 2 · 31 Jul 2012 · 9,082 accessesView PDFCite
Research ArticleOpen accessIn the abstractGPS Ionospheric Total Electron Content and Scintillation Measurements during the October 2003 Magnetic StormMohammad Awad Momani, Takialddin A. Al Smadi, Farouq M. Al Taweel, Khaldoon A. GhaidanProblem Statement: Ionospheric scintillations, cause significant effects on satellite signals for communication and navigation in equatorial region and polar regions mainly during sever magnetic storms periods. This phenomenon is not fully understood due to few studies performed. The study investigates variability of Total Electron Content (TEC) and ionospheric scintillation during October 2003 magnetic storm over Antarctica using ground based GPS … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Variable Neighborhood Search Algorithm for Assigning Cells to Switches in Wireless NetworksMatthieu Andr, Gilles Pesant, Samuel PierreThe problem of assigning cells to switches in wireless networks consists of minimizing the total operating cost, that is, the cost of linking cells to switches and the cost of handover from one cell to another, by taking into account factors such as network topology, switch capacity and traffic load in the entire network. Such a problem is well known … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,748 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAdaptive Neuro-Fuzzy Inference System Approach for the Automatic Screening of Diabetic Retinopathy in Fundus ImagesS. Kavitha, K. DuraiswamyProblem statement: Diabetic retinopathy is one of the most significant factors contributing to blindness and so early diagnosis and timely treatment is particularly important to prevent visual loss. Approach: An integrated approach for extraction of blood vessels and exudates detection was proposed to screen diabetic retinopathy. An automated classifier was developed based on Adaptive Neuro-Fuzzy Inference System (ANFIS) to differentiate … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,785 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPrediction on Land Market Value Based on the Real Estate Market in USALei WangThe Land Market Value, defined as the total value of land price and quantity data are derived from data on housing values, is an important factor in the estimation of structure costs using price indexes for housing and construction costs. In this study, we gather and analyze 34 years' national data on past and present real estate transaction.

Research ArticleOpen accessAll words, across the recordAn Analysis of Power Aware Congestion Control Multipath Multicast Protocol for Mobile Ad hoc NetworkDuraiswamy Karuppaswamy, Vijayaragavan ShanmugamProblem statement: In MANETs, wireless link transmission errors, mobility and congestion are major causes for packet loss. Mobility may cause packet loss in different ways. Whereas congestion in a network occurs, whenever the demands exceed the maximum capacity of a communication link especially when multiple hosts try to access a shared media simultaneously. Approach: In this study, we proposed a … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 7,038 accessesView PDFCite
