Research ArticleOpen accessIn the abstractAn Algorithm for Determining the Number of Mixture Components on the Bayesian Mixture Model Averaging for Microarray DataAni Budi Astuti, Nur Iriawan, Irhamah, Heri KuswantoThe major challenges on the statistical analysis of microarray data are the limited availability of samples, large number of measured variables and the complexity of distribution of the data obtained (e.g., multimodal). These phenomena could be considered in Bayesian method, used Bayesian Mixture Model (BMM) methods and Bayesian Model Averaging (BMA) methods. Modeling of Bayesian Mixture Model Averaging (BMMA) for … …Journal of Mathematics and Statistics, Vol. 11, Issue 2 · 28 Sep 2015 · 7,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Channel Estimation and Performance Analysis Using H-Infinity Filter for MIMO-Orthogonal Frequency Division Multiplexing SystemsJoseph Gladwin Sekar, Salivahanan SankarappanThis paper, deals with H-infinity channel estimation technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, in fading channel. Channel estimation is important for wireless applications because, in practical transmission scenario, channel correlation functions are either not known or cannot be easily estimated. It is therefore desirable to have an estimator which is robust to mismatches between the assumed and the … …Journal of Computer Science, Vol. 11, Issue 2 · 29 Jan 2015 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractA LOW-COST EFFECTIVE UWB LOCATION SYSTEM BASED ON FREQUENCY SYNTHESIS TECHNOLOGYQilong Zhang, Fei QinWireless location system based on UWB signals has been widely utilized by wireless network recently, especially for the indoor scenarios where GPS signal has been heavily attenuated. However, due to the requirement of ultra wideband signals, existing location system usually faces problems including complexity, robust and cost, which limit the potential applications. In this study, we propose a new approach … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Dec 2014 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic Batch Mode Heuristic Algorithm for Mapping Independent Tasks in Computational GridR. Vijayalakshmi, V. VasudevanGrid computing plays an important role in solving large-scale computational problems in a high performance computing environment. Scheduling of tasks to efficient and best suitable resource is one of the most challenging phase in grid computing systems. Grid environment reveals several challenges in efficient scheduling of complex applications because of its heterogeneity, dynamic behavior and shared resources. Scheduling of independent … …Journal of Computer Science, Vol. 11, Issue 1 · 22 Sep 2014 · 7,429 accessesView PDFCite
Research ArticleOpen accessIn the abstractDISTRIBUTION OF LOAD USING MOBILE AGENT IN DISTRIBUTED WEB SERVERSVijayakumar G. Dhas, V. Rhymend UthariarajThe continuing growth of the World-Wide Web is placing increasing demands on popular Web servers. Many of the sites are now using distributed Web servers (i.e., groups of machines) to service the increasing number of client requests, as a single server cannot handle the workload. Incoming client requests must be distributed in some fashion among the machines in the distributed … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 28 Feb 2014 · 6,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractTRUST BASED AUTOMATIC QUERY FORMULATION SEARCH ON EXPERT AND KNOWLEDGE USERS SYSTEMSK. Sridharan, M. ChitraDue to enhance in complexity of services, there is a necessity for dynamic interaction models. For a service-oriented system to work properly, we need a context-sensitive trust based search. Automatic information transfer is also deficient when unexpected query is given. However, it shows that search engines are vulnerable in answering intellectual queries and shows an unreliable outcome. The user cannot … …Journal of Computer Science, Vol. 10, Issue 7 · 18 Feb 2014 · 6,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECTIVE HEURISTIC ALGORITHM FOR DYNAMIC ROUTING AND BANDWIDTH MANAGEMENT UNDER QUALITY OF SERVICE CONSTRAINTS IN MULTISTAGE INTERCONNECTION NETWORKSR. Deepalakshmi, S. RajaramToday, Internet of Things (IoT) has introduced abundant bandwidth consumption and necessities in multimedia communications from online games to video-conferencing applications with the constraint of QoS requirements from time to time. The expected rapid proliferation of services would require performance unprecedented in the currently available best-effort routing algorithms. In, particular, the present routing mechanisms are based on the best-effort paradigm … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 7 Jan 2014 · 7,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractOPTIMIZING MULTIPLE TRAVELLING SALESMAN PROBLEM CONSIDERING THE ROAD CAPACITYRanjana Ponraj, George AmalanathanThe Multiple Travelling Salesman Problems (MTSP) can be used in a wide range of discrete optimization problems. As the solution to this problem has wide applicability in many practical fields, this NP Hard problem highly raises the need for an efficient solution. The problem is determining a set of routes for the salesmen that jointly visit a set of given … …Journal of Computer Science, Vol. 10, Issue 4 · 23 Dec 2013 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractANALYSIS OF REDUCTION IN COMPLEXITY OF MULTIPLE INPUT- MULTIPLE OUTPUT-ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMS WITH CARRIER FREQUENCY OFFSET ESTIMATION AND CORRECTIONSabitha Gauni, Kumar RamamoorthyOrthogonal Frequency Division Multiplexing (OFDM) is a promising research area in Wireless Communication for high data rates. The Multiple Input-Multiple Output (MIMO) technology when incorporated with the OFDM system promise a significant boost in the performance. But, the MIMO-OFDM systems are very sensitive to Carrier Frequency Offset (CFO) as it deteriorates the system performance with the rise of Inter-Carrier-Interference (ICI). … …Journal of Computer Science, Vol. 10, Issue 2 · 13 Nov 2013 · 6,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Channel Estimation Technique for Complexity Reduction of Least Minimum Mean Square ErrorHany Mohamed El-Ansary, Hussein Ghouz, Ashraf Mamdouh Aziz, Gamal MabroukChannel estimation technique is to predict the frequency response of the radio channel using pilot signal. Channel estimation technique is important part of LTE receiver design. Such technique is used to recover the transmitted signal correctly and to know how the channel conditions are changed over frequency and time.
