Research ArticleOpen accessIn the abstractHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,595 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDFCite

Purpose: Modeling the characteristics of personality and motivation of medical student's development following the establishment of an appropriate methodology to act in university physical education lessons by developing and implementing a strategic program included in organization, management and conduct training process-education, the means of … …Journal of Social Sciences, Vol. 7, Issue 4 · 10 Aug 2011 · 8,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproximate Maximum Likelihood Commercial Bank Loan Management ModelGodwin Norense Osarumwense AsemotaProblem statement: Loan management is a very complex and yet, a vitally important aspect of any commercial bank operations. The balance sheet position shows the main sources of funds as deposits and shareholders contributions. Approach: In order to operate profitably, remain solvent and consequently grow, a commercial bank needs to properly manage its excess cash to yield returns in the … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Fully Coupled Approach for Evaluation of Wellbore Stability in Hydrocarbon ReservoirsVera RoccaProblem statement: When a well is drilled in a hydrocarbon reservoir, the original thermodynamic conditions are altered, the natural stresses are redistributed and a stress concentration occurs around the hole. The alteration of the original equilibrium can lead to wellbore damage, sometimes to its complete collapse. Loss of time associated with stability problems is estimated to account for 12-15% of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,564 accessesView PDFCite
Review ArticleOpen accessIn the abstractMechatronics Around the World - at a GlanceRachita Sharma, Bhaskar DhimanIncreasing performance standards for complex procedures, which includes business equipment and their steadily growing technical importance, might require new processes to be applied within the procedure of product advent. The important thing concept in the back of our proposed approach is to combine one of a kind stages consisting of design, simulation and physical implementations in product or device advent. … …Journal of Mechatronics and Robotics, Vol. 5, Issue 1 · 12 Feb 2021 · 7,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling Chaos of the Ricker Population Model by OGY MethodGuo FengThe chaotic dynamics of the Ricker mapping are studied. Controlling chaos of the Ricker population model is searched by OGY control method. The dynamic behavior in the Ricker mapping is very complex in different values of a. When the value of a is changed from 0.455 to 90, the mapping goes through doubling bifurcation to Neimark-Sacker bifurcation. Several strange attractors … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 8 Sep 2020 · 6,219 accessesView PDFCite
