Research ArticleOpen accessIn the abstractCombined Heuristic Technique for Optimization of Bloom Filter in Spam FilteringArulanand Natarajan, S. Subramanian, K. PremalathaProblem statement: Spam is an irrelevant or inappropriate message sent on the internet to a large number of newsgroups or users. A spam word is a list of well-known words that often appear in spam mails. Bloom Filter (BF) is used for identification of spam word. Approach: BF is a simple but powerful data structure that can check membership to … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 7,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Controllers for Permanent Magnet Brushless DC Motor Drive System using Adaptive-Network-based Fuzzy Interference SystemV.M. Varatharaju, Badrilal Mathur, UdhayakumarProblem statement: The tuning methodology for the parameters of adaptive speed controller causes a transient deviation of the response from the set reference following variation in load torque in a permanent-magnet brushless DC (BLDC) motor drive system. Approach: This study develops a mathematical model of the BLDC drive system, firstly. Secondly, discusses a design of the closed loop drive system … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractOR-Bridging Fault Identification and Diagnosis for Exclusive-OR Sum of Products Reed-Muller Canonical CircuitsV. Geetha, N. Devarajan, P. N. NeelakantanProblem statement: The faults in digital circuit can be classified broadly as single stuck-atfaults, multiple stuck-ay-faults, stuck-open faults, stuck-on faults, path delay faults, transient faults. Extensive research had been carried out in the field of testing of digital circuits to limit the number of input vectors. The cardinality of the test vectors proposed by many authors was quite high for … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpacts of Typhoon on Wave Height at Bangkhuntien ShorelinePrasertsak Ekphisutsuntorn, Prungchan Wongwises, Jiang Zhu, Suphat VongvisessomjaiProblem statement: In this study, the changing of wave height at Bangkhuntien during a passage of typhoon LINDA was simulated by using the Simulating WAves Nearshore Model (SWAN) version 40.41. The study domain covered from 99-101°E longitude and 12-14°N in latitude with resolution of 2.4×2.4 km. The simulation covered 10 days during typhoon LINDA entering into the Upper Gulf of … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Simulating WAves Nearshore Model for Wave Height Simulation at Bangkhuntien ShorelinePrasertsak Ekphisutsuntorn, Prungchan Wongwises, Chaiyuth Chinnarasri et al.Problem statement: In this study, the significant wave height at the Upper Gulf of Thailand and the change of wave height at Bangkhuntien shoreline were simulated by using the Simulating WAves Nearshore Model (SWAN) version 40.51. Approach: The simulated significant wave height by the SWAN model at Petchburi buoy station and Ko Srichang buoy station were compared with the observed … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractMemory Storage Issues of Temporal Database Applications on Relational Database Management SystemsSami M. Halawani, Nashwan A. Al-RomemaProblem statement: Many existing database applications manage time-varying data. These database applications are referred to as temporal databases or time-oriented database applications that are considered as repositories of time-dependent data. Many proposals have been introduced for developing time-oriented database applications, some of which suggest building support for Temporal Database Management Systems (TDBMS) on top of existing non-temporal DBMSs, while others … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterface Micromotion of Cementless Hip Stems in Simulated Hip ArthroplastyMohammed Rafiq Abdul Kadir, Nazri KamsahProblem statement: The design of hip prostheses has evolved over time due to various complications found after hip replacement surgery. The currently commercially available cementless femoral stems can be categorized into one of three major types, straight cylindrical, tapered rectangular and anatomical. Each type proposes a unique concept to achieve primary stability-a major requirement for bone healing process. Virtual analyses … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Sucrose in the Development of Oral Biofilm in a Simulated Mouth SystemWan Nordini Hasnor Wan Ismail, Fathilah Abdul Razak, Zubaidah Hj Abdul RahimThe development of oral biofilm consisting of early settlers and late settlers in the presence and absence of sucrose using a simulated mouth model was investigated. The experiments were carried out by growing the early settlers’ biofilm consisting of Strep. mitis and Strep. sanguinis and late settlers’ biofilm of Strep. mutans in the simulated mouth system. Experiments using three different … …OnLine Journal of Biological Sciences, Vol. 6, Issue 2 · 31 Dec 2006 · 7,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic and Dynamic Mechanical Behavior of Hydroxyapatite-Polyacrylic Acid Composites Under Simulated Body FluidKalpana S. Katti, Phanikumar Turlapati, Devendra Verma et al.In this work, we have investigated mechanical response of hydroxyapatite/polyacrylic composites under dry, wet and simulated body fluid conditions. Hydroxyapatite (HAP) is mineralized under two conditions; one, in presence of polyacrylic acid (in situ HAP), second, in absence of polyacrylic acid (ex situ HAP). Further, in situ and ex situ HAP are mixed with polyacrylic acid to make HAP/PAAc composites. … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractRedundancy Schemes for High Availability Computer ClustersChristian K. Bassek, Samuel Pierre, Alejandro QuinteroThe primary goal of computer clusters is to improve computing performances by taking advantage of the parallelism they intrinsically provide. Moreover, their use of redundant hardware components enables them to offer high availability services. In this paper, we present an analytical model for analyzing redundancy schemes and their impact on the cluster’s overall performance. Furthermore, several cluster redundancy techniques are … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,236 accessesView PDFCite
