Research ArticleOpen accessAll words, across the recordToward Clean Green Sustainable Development to Prevent the First Food World War, Changing Authoritative-Public Extension to Literalized-Partnership Extension SystemIraj MalakmohammadiProblem statement: The main purpose in this study is to provide a more rational platform in extension modeling to respond to the very recent world-wide warnings calling up for global revision of the present extension practices to put the appropriate science and technology to application to securing Clean-Green Sustainable Development (CGSD). Approach: To achieve this purpose, extension education was reconsidered … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,044 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordShort-Term and Medium-Term Load Forecasting for Jordan's Power SystemI. Badran, H. El-Zayyat, G. HalasaSeveral electric power companies are now forecasting electric loads based on conventional methods. However, since the relationship between loads and factors influencing these loads is nonlinear, it is difficult to identify its nonlinearity by using conventional methods. Most of papers deal with 24-h-ahead load forecasting or next day peak load forecasting. These methods forecast the demand power by using forecasted … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,081 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEstimation of Naturally Modified Mineral Water Protection Activity Against Experimental InfectionsEdward Vladimir Krizhanovsky, Kwong Choong LimAn estimation of protective efficiency of naturally modified mineral water (BAE Synergy Liquid preparation) was performed on animals in models of flue and anthrax infections. The preparation exhibited a significant effect as a preventive and therapeutic agent at these infections. …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,873 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign and Modeling of a New Tactile Sensor Based on Membrane DeflectionAli Tavakoli Golpaygani, Siamak Najarian, Goldis Darb EmamiehThe designed sensor can detect 2D surface texture image, contact-force, and softness of the sensed object. It consists of a chamber for pneumatic actuation and a membrane with a mesa structure. The sensing mechanism is the contact deformation effect of a membrane. Determination of the contact force and softness of sensed object is based on the amount and variations of … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,786 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLow Complexity Performance Effective Task Scheduling Algorithm for Heterogeneous Computing EnvironmentsE. Ilavarasan, P. ThambiduraiA heterogeneous computing environment is a suite of heterogeneous processors interconnected by high-speed networks, thereby promising high speed processing of computationally intensive applications with diverse computing needs. Scheduling of an application modeled by Directed Acyclic Graph (DAG) is a key issue when aiming at high performance in this kind of environment. The problem is generally addressed in terms of task … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 9,663 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,789 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordE-Learning under WebCTZ. A. Al-Khanjari, N. S. Kutti, H. A. RamadhanWith the introduction of Web-Based Instruction (WBI) the traditional classroom-based higher education could be made more effective form of instruction. But the studies have shown the negative results[1]. On the other hand the distance education has derived the direct benefit of WBI through extending classroom instruction in online to reach every remote student. However researchers have identified reasons for the … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,320 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFault-tolerant Distributed Systems with Diagnostics AlgorithmsOleg Viktorov, Afif MghawishTo provide consistent actions in distributed systems with faulty nodes the Byzantine agreement protocol (algorithm) is widely used. In case of using message exchange scheme without authentication the Byzantine agreement algorithm leads to agreement if the number of nodes doesn’t exceed 1/3 of the total number. The proposed algorithms based on diagnostics procedures are used to reach an agreement in … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,840 accessesView PDFCite
