Research ArticleOpen accessIn the keywordsEXTENDED-RANDOMIZED, EFFICIENT, DISTRIBUTED: A DYNAMIC DETECTION OF CLONE ATTACKS IN STATIC WIRELESS SENSOR NETWORKSC. Geetha, M. RamakrishnanA wireless sensor network is a collection of nodes organized in to a cooperative network. Each node consists of processing capability, multiple types of memory, a power source and actuators and sensors. This wireless sensor network is established in hostile and harsh environments like civil and military applications. This network is prone to various attacks. One of the major attack … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 6,742 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOperational Fault Diagnosis in Industrial Hydraulic Systems Through Modeling The Internal Leakage of its ComponentsP. Athanasatos, D. Koulocheris, T. Costopoulos, K. RaptisIn this study, a model of a high pressure hydraulic system was developed using the bond graph method to investigate the effect of the internal leakage of its main components (pump, cylinder and 4/2 way valve) on the operational characteristics of the system under various loads. All the main aspects of the hydraulic circuit (like the internal leakages, the compressibility … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMathematical Analysis of How the Electrical Training Center Site is Affected by Air PollutionBassam A. Al-HelouThe study has come to the result that the monitoring site at the Electrical Training Centre (ETC) at Al-Hashimyeh town is exposed to grave pollution that goes beyond Jordanian standards of the ambient air. It has, indeed, shown that Sulfur dioxide (SO2) exceeds the limits and its seasonal concentration matches forward with the average wind speed. SO2 concentration reaches its … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 3 Sep 2012 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImproved Vertex Chain Code Based Mapping Algorithm for Curve Length EstimationHabibollah Haron, Amjad Rehman, L.A. Wulandhari, Tanzila SabaProblem statement: Image representation has always been an important and interesting topic in image processing and pattern recognition. However, curve tracing and its relative operations are the main bottleneck. Approach: This research presents the mapping algorithm that covers one of the vertex chain code cells, the rectangular-VCC cell. The mapping algorithm consists of a cell-representation algorithm that represents a thinned … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,841 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Practical Approach of Selecting the Edge Detector Parameters to Achieve a Good Edge Map of the Gray ImageAkram A. Moustafa, Ziad A. AlqadiProblem statement: practical approach of detecting edge map was proposed. Approach: The methodology of this approach was presented and tested in order to select the best value of the operator, used to smooth and get the gradient, and the threshold value used to convert the gray gradient to binary edge map, so a practical value of the threshold and edge … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Clock Tree Synthesis Under Stochastic Process Variation Modeling for Multi-FPGA SystemsKarthik Thirumalai Sampath, Jawahar Senthil Kumar VeerabadranIn this age of scientific computing, the experiment models and evaluation is a commonly employed rendition of the simulation methods. In addition to the optimality, the methods which depict underlying uncertainty in process variation. It is accomplished by adjusting number of samples on delay and wire width. Here addresses the thermal profile, if temperature gradually increases, also reduce worst case … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 29 Oct 2013 · 6,510 accessesView PDFCite

In order to improve the existing varieties of crops and obtain new, valuable varieties, it is very important to document, preserve and enrich their gene pool, while preserving local varieties and … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 11 Sep 2023 · 4,629 accessesView PDFCite
Review ArticleOpen accessIn the abstractEnhancement of GPS Position Accuracy Using Machine Vision and Deep Learning TechniquesAshwani Kumar AggarwalThe accuracy of GPS position estimation in urban cities is an issue which need to be resolved using machine vision and deep learning techniques. The accuracy of GPS in horizontal direction is better than in the vertical direction. Although for most of the navigation applications in intelligent transportation systems, horizontal positioning accuracy is vital, but vertical position accuracy gives idea … …Journal of Computer Science, Vol. 16, Issue 5 · 25 May 2020 · 18,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Organic Ameliorants on Grey Soil FertilityAsanbay Tagaev, Amandyk Kostakov, Sabir MakhmadzhanovThe study aimed to assess the effectiveness of organic-biological ameliorants for restoring the fertility of light grey soils in the Turkestan region of Kazakhstan, which are characterised by low humus content (0.8-1.1%) and high alkalinity (pH 7.9-8.3). The field experiment was conducted on an area of 2304 m2 using four treatment options: control (variant 1 only mineral fertilisers) and three … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 15 Sep 2026 · 693 accessesView PDFCite
