Research ArticleOpen accessIn the abstractHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Intra Uterine Insemination in the Treatment of InfertilityNabila Kamil Yaaqoub, Bushra Mohammed MajedProblem statement: To assess efficacy of IUI in treatment of infertility. Tikrit teaching hospital. Approach: 42 infertile couple underwent standard evaluation for infertility, woman given medication to stimulate development of mature follicles, washed semen specimen placed in uterine cavity using sterile flexible catheter, coincide with ovulation time. Results: Of 42 infertile couples pregnancy occur in 26(61.9%), (19.1%) in primary and … …Current Research in Medicine, Vol. 2, Issue 1 · 9 Jul 2011 · 7,151 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Congestion Reduction Routing in Wireless Sensor NetworksT. V.P. Sundararajan, Thiyaneswaran Manoharan, Abinaya RajendranProblem statement: Data generated in wireless sensor networks may not all be alike: some data may be more important than others and hence may have different delivery requirements, To solve this problem addressed a differentiated data delivery in the presence of congestion in wireless sensor networks and proposed a class of algorithms that enforce differentiated routing based on the congested … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractMisbehaving Node Detection in Mobile Ad Hoc Networks using Multi Hop Acknowledgement SchemeUsha Sakthivel, S. RadhaProblem statement: For any node in a Mobile Ad hoc Network conservation of battery power and bandwidth are the priority. Hence, they try to reduce the overload they would otherwise incur when they forward packets. This selfish behavior of a node affects the throughput of the network. The nodes may also choose a back off value of shorter duration. These … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of Composite Material from Sea Mussel Shells and White Clay as a Versatile SorbentSingto Sakulkhaemaruethai, Churairat Duangduen, Weraporn Pivsa-Art, Sommai Pivsa-ArtProblem statement: The removal of heavy metals contaminated in aqueous solution/wastewater has been causing worldwide concern. However, the adsorbent materials are usually limited due to their high cost and environmentally benign. To overcome the above-mentioned disadvantages, low-cost and effective adsorbents are in demand. Approach: In this study, the sea mussel shells/natural clay beads were prepared for using as low-cost sorbent … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrasonography and Radiography Evaluation of the Cartilage Graft in Repair of Experimentally Induced Radial Bone Defect in RabbitFoad Sadi, Abbas Veshkini, Davood Sharifi, M Nasroulahzadeh MasoulehWe would like to thank to the Faculty of Specialized Veterinary Sciences research council. Science and Research Branch of Islamic Azad University, Punak Tehran for approval and financial support to finish this project. Problems statement: The purpose of this research was to determine the biological effect of cartilage graft as a bone defect filler and osteogenetic stimulation to speed up … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Substrate-Borne Vibrational Signals of Euschistus servus (Heteroptera: Pentatomidae)Brittany Lampson, Young Han, Ahmad Khalilian et al.Problem Statement: Stink bugs were not major pests of cotton in the southeastern United States until cotton varieties containing Bacillus thuringiensis (Bt) transgenes came into common use, enabling reductions in insecticide applications against highly destructive lepidopteran pests. To maintain the benefits of reduced insecticide applications, it would be advantageous to detect and target isolated populations of stink bugs before they … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoltage Sag Effects on the Process Continuity of a Refinery with Induction Motors LoadsTarek I. ElShennawy, Mahmoud A. El-Gammal, Amr Y. Abou-GhazalaProblem statement: Process continuity of industrial plants (like a refinery) is subjected to several shutdowns due to voltage sags causing large induction motors to trip, either by undervoltage or by overcurrent relays, sometimes by the mechanical protection. These unplanned shutdowns cost the plant tens of thousands of dollars per shutdown in addition to material damage costs, restart charges and any … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,120 accessesView PDFCite
