Research ArticleOpen accessIn the abstractThe Lense-Thirring Effect in the Anomalistic Period of Celestial BodiesIoannis Haranas, Omiros Ragos, Ioannis GkigkitzisIn the weak field and slow motion approximation, the general relativistic field equations are linearized, resembling those of the electromagnetic theory. In a way analogous to that of a moving charge generating a magnetic field, a mass-energy current can produce a gravitomagnetic field. In this contribution, the motion of a secondary celestial body is studied under the influence of the … …Space Science International, Vol. 1, Issue 2 · 9 Dec 2013 · 8,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOST-BENEFIT ANALYSIS OF A SINGLE UNIT SYSTEM WITH SCHEDULED MAINTENANCE AND VARIATION IN DEMANDGulshan Taneja, Reetu MalhotraThe present paper analyses the reliability and cost-benefit for a single unit system with scheduled maintenance and variation in demand. As Change in demand affects the production of system also, hence sometimes, the system needs to be shut down when the number of produces are in excess as compared to those demanded. Revenue in case of both types of up … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 30 May 2013 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the abstractNelder-Mead Method with Local Selection Using Neighborhood and Memory for Stochastic OptimizationNoocharin Tippayawannakorn, Juta PichitlamkenWe consider the Nelder-Mead (NM) simplex algorithm for optimization of discrete-event stochastic simulation models. We propose new modifications of NM to reduce computational time and to improve quality of the estimated optimal solutions. Our means include utilizing past information of already seen solutions, expanding search space to their neighborhood and using adaptive sample sizes. We compare performance of these extensions … …Journal of Computer Science, Vol. 9, Issue 4 · 10 May 2013 · 6,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractStock Market Development and Economic Growth an Empirical AnalysisVazakidis Athanasios, Adamopoulos AntoniosThis study investigated the causal relationship between stock market development and economic growth for Greece for the period 1978-2007 using a Vector Error Correction Model (VECM). Questions were raised whether stock market development causes economic growth taking into account the negative effect of interest rate on stock market development. The purpose of this study was to investigate the short-run and … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 12 Jun 2012 · 13,859 accessesView PDFCite

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 abstractCredit Market Development and Economic Growth an Empirical Analysis for GreeceAthanasios Vazakidis, Antonios AdamopoulosProblem statement: This study investigated the relationship between credit market development and economic growth for Greece for the period 1979-2007 using a Vector Error Correction Model (VECM). Questions were raised whether economic growth spurs credit market development taking into account the negative effect of inflation rate on credit market development. This study aimed to investigate the short-run and the long-run … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdiponectin mRNA Expression in the Cat (Felis domesticus)Angela L. Lusby, Stephen A. Kania, Joseph W. Bartges, Claudia A. KirkProblem statement: Adiponectin is a hormone expressed from adipose tissue in people, rodents and dogs. Adiponectin has anti-inflammatory action with beneficial effects on cardiovascular health and insulin sensitivity. With increasing fat mass, adiponectin concentrations paradoxically decrease. Adiponectin’s role in metabolism and diabetes mellitus is of interest in feline medicine because cats are susceptible to developing type II diabetes with weight … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Wall Roughness and Concentration of Clay on Erosion in the Hole Erosion TestKissi Benaissa, Parron Vera Miguel Angel, Rubio Cintas Maria Dolores et al.Problem statement: Internal soil erosion is a real threat for hydraulic infrastructures. In its final stage it develops in piping involving the formation and progression of a continuous void inside the soil between the upstream and downstream sides. The hole erosion test was introduced to characterize kinematics of piping in terms of the time left to rupture. Actual modeling approaches … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,506 accessesView PDFCite
