Research ArticleOpen accessEvery word in the titleOn the Mean Estimation using Stratified Double Median Ranked Set SamplingMahmoud Ibrahim Syam, Amer Ibrahim Al-Omari, Kamarulzaman IbrahimStratified Double Median Ranked Set Sampling (SDMRSS) method is suggested for estimating the population mean. The SDMRSS is compared with the Simple Random Sampling (SRS), Stratified Simple Random Sampling (SSRS) and Stratified Ranked Set Sampling (SRSS) methods. It is shown that SDMRSS estimator is an unbiased of the population mean and is more efficient than the SRS, SSRS and SRSS … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 12 Apr 2017 · 7,579 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRandomized Response Procedure for the Estimation of the Population Ratio using Ranked Set SamplingAgustin Santiago, Carlos N. Bouza, J. Maclovio Sautto, Amer Ibrahim Al-OmariIn this study we deal with the estimation of the population ratio, when a Randomized Response (RR) procedure is used for collecting responses and Ranked Set Sampling (RSS) is the selection method. The variances of the suggested estimators are calculated. Comparisons between different estimators are presented. …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 27 Apr 2016 · 7,400 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFICIENT RANKED AND SECURE FILE RETRIEVAL IN CLOUD COMPUTINGJ. Jospin Jeya, E. KannanCloud computing facilitates extremely scalable services that can be consumed over internet. An important aspect of the cloud services is that user data are stored remotely in unknown machines in which users do not posses or manage. Since the data’s are stored remotely, we have to keep in mind that sensitive cloud data have to be encrypted before they are … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 6,856 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA MULTI ATTRIBUTE RANKING MECHANISM FOR PEER-TO-PEER NETWORKSSheila Anand, B. SwaminathanP2P systems are envisioned to play a greater role in collaborative applications. P2P environments remove the challenging task of using servers for information sharing. Emerging collaborative P2P systems require discovery and utilization of multi-attribute, distributed and dynamic group of resources to achieve greater tasks beyond conventional file and processor cycle sharing. The process of selection of a peer for collaborative … …Journal of Computer Science, Vol. 10, Issue 8 · 24 Feb 2014 · 6,882 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleRelevance Ranking for Services RetrievalHassania Ouchetto, Ouail Ouchetto, Ounsa RoudiesProblem statement: One of the challenges of e-gov systems is to provide, during a search process, relevant services that meet user expectations. Indeed, obtaining relevant information responding to user queries is a difficult process. It becomes even complex when the query terms have many meanings and do not fit with the vocabulary used by the services. Approach: We propose an … …Journal of Computer Science, Vol. 8, Issue 10 · 27 Aug 2012 · 6,701 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Page Ranking Algorithm for a Personalized Web SearchJ. Jayanthi, K. S. JayakumarProblem statement: Information on the web is growing exponentially. Today, traditional search engines provide results mainly based on the user’s query. Though the context of the query varies, the returned result seems to be same for all users. Accordingly users are expected to search for the relevant results, which is an added overhead to the users. Approach: We propose a … …Journal of Computer Science, Vol. 8, Issue 7 · 12 May 2012 · 6,998 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Approach Using Data Envelopment Analysis for Ranking Classification AlgorithmsA. Bazleh, P. Gholami, F. SoleymaniProblem statement: A variety of methods and algorithms for classification problems have been developed recently. But the main question is that how to select an appropriate and effective classification algorithm. This has always been an important and difficult issue. Approach: Since the classification algorithm selection task needs to examine more than one criterion such as accuracy and computational time, it … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 15 Sep 2011 · 7,446 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Enhanced Russell Measure of Super-Efficiency for Ranking Efficient Units in Data Envelopment AnalysisAli Ashrafi, Azmi Bin Jaafar, Lai Soon Lee, Mohd Rizam Abu BakarProblem statement: Conventional Data Envelopment Analysis (DEA) helps decision makers to discriminate between efficient and inefficient Decision Making Units (DMUs). However, DEA does not provide more information about the efficient DMUs. Super-efficiency DEA model can be used in ranking the performance of efficient DMUs. Because of the possible infeasibility of radial super-efficiency DEA model, the ranking has been limited to … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 8,800 accessesView PDFCite
