Research NotesOpen accessIn the abstractA Comprehensive Study on Mobility Issues in AODVThiripurasundari SivakrishnakumarAd-hoc network plays an important role in wireless networks as they are self-configured and can be operated independently with limited resources. The critical issue is to assess the performance of routing protocols in Mobile Ad hoc Network (MANET) due to the frequent changes in network topology. Here the Ad-hoc On demand Distance Vector (AODV) routing protocol, which is quite susceptible … …Journal of Computer Science, Vol. 11, Issue 10 · 2 Jan 2016 · 6,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractSedimentology and Ichnology of Late Oligocene Delta Front Reservoir Sandstone Deposit, Greater Ughelli Depobelt, Niger DeltaRaphael Oaikhena Oyanyan, Michael Ndubuisi OtiSedimentological and ichnological study of cored reservoir sands correlated with wireline logs between two wells, 0.8 km distance apart along dip direction, enabled vertical and cross sectional facies variability assessment aimed at determining intra sand-body continuity in longitudinal or down-dip direction; and sub-environments of deposition and factors that controlled depositional processes. Ten lithofacies described 62 meters cores of the reservoir … …Current Research in Geoscience, Vol. 5, Issue 1 · 30 Jul 2015 · 7,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometrical Synthesis of the Distribution MechanismsFlorian Ion T. PetrescuIn this study the author presents shortly some few original trigonometric methods to make the synthesis of some main distribution mechanisms. One presents four main modules of distribution mechanisms, with rotary cam and translated or rotated tappet plane or with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. These types of distribution mechanisms … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 13 Apr 2015 · 8,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractEMERGING TRENDS IN ADAPTIVE COMPUTATION FOR MOBIQUITOUS SYSTEMSJesus FriginalThe future is in networked embedded systems. This affirmation is based on the principle that networked embedded systems will make possible the development of more intelligent living, work, entertainment, energy production systems and transport environments. It is estimated that the number of networked smart objects on a planetary scale will increase beyond20 billion units by 2020, thus promoting the emergence … …Journal of Computer Science, Vol. 10, Issue 11 · 19 Aug 2014 · 8,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE MODEL IN PREVENTING AND SOLVING DRUGS IN THE THAI-LAO BORDER VILLAGESWattana Puttichart, Saner Piromjitpong, Metta MettkarunjitA drug issue is a problem at both national and international levels. The root causes of the problems lie inside and outside the humans. To solve the problems in a sustainable way, it is essential to get cooperation from many parties. The research aimed to study the situations and prevention and solution of drugs in the border villages, to construct … …Journal of Social Sciences, Vol. 10, Issue 1 · 18 Apr 2014 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrological and Sediment Transport Simulation to Assess the Impact of Dam Construction in the Mekong River Main ChannelSatoshi Kameyama, Hiroto Shimazaki, Seiichi Nohara et al.The downstream impact of dams is a complex problem in watershed management. In the upper Mekong River watershed and its main channel, dam construction projects were started in the 1950s to meet increasing demands for energy and food production. Dams called the Mekong Cascade were completed on the Mekong River in China, the Manwan Dam in 1996 and the Dachaoshan … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 29 Jun 2013 · 8,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Simulation of the Transient Flow in Natural Gas Transmission Lines Using a Computational Fluid Dynamic MethodPedram Ghaseminejad, Nikan NoorbeheshtUntil now, almost all tools that are used to analyze gas transportation networks are based on steady flow conditions. Some design problems can be solved by the assumption of a steady state. However, some circumstances force us to use transient analyses, which commonly include changes in customer demand, the failure of a compressor station or gas pipeline ruptures. In this … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 6 Jan 2013 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportace of the International Council of Environmental Engineering EducationIstvan PatkoProblem statement: Due to the climatic changes and the ecological variations of the biosphere, global natural resources including the atmosphere, hydrosphere, lithosphere, biodiversities, genetic resources and energy, radiation, electric charge and magnetism, must be safeguarded for the benefit of present and future generations through careful planning and management as appropriate. Approach: The main points of the International Council of Environmental … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 27 Mar 2012 · 7,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,906 accessesView PDFCite
