Research ArticleOpen accessAll words, across the recordEXTENDED-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 accessAll words, across the recordParsimonious Var Models For Air Pollution Dynamic AnalysisFontanella lara, Granturco mariagraziaWe discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,181 accessesView PDFCite

RajaramProblem statement: With the explosive growth of and internet and web applications many emerging group-oriented distributed applications such as tele/video-conferencing, multiplayer games are based on group communication model that need security services such as privacy and data integrity Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,643 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSpeech Segmentation Using Dynamic Windows and Thresholds for Arabic and English LanguagesYahia Hasan JazyahSegmentation of audio data such as human speech (splitting each word in separate audio file – .WAV file) has been a major concern when working with multimedia such as recordings from radio or TV. The main focus of the segmentation of boundaries of spoken language has been on using energy and zero crossing thresholds for endpoint detection. Errors in endpoint … …Journal of Computer Science, Vol. 14, Issue 4 · 18 Apr 2018 · 7,778 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Empirical Study of Efficiency Evaluation with Dynamic Strategy Trajectory Based on DEA Algorithm and BCG Model: A Case Study of Securities IndustryCheng-Shian Lin, Chun-Yueh LinThe U.S. Subprime Mortgage Crisis in 2008 led many financial institutions, including those in the securities industry, to the verge of bankruptcy. As the securities industry has a pivotal position in financial markets, this study aims to use Data Envelopment Analysis (DEA) to discuss the efficiency of the securities industry after the Financial Tsunami. In addition, this paper integrates the … …Journal of Social Sciences, Vol. 14, Issue 1 · 4 Apr 2018 · 8,166 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRandomness Analysis of DES Ciphers Produced with Various Dynamic ArrangementsMalik Qasaimeh, Raad S. Al-QassasOver the past few years, researchers have devoted efforts to enhance the original DES encryption algorithm. These enhancements focus on improving multiple perspectives of the algorithm through enhancing its internal components to deliver a robust DES variant against different kinds of typical attacks such as linear and differential crypto analysis, in addition to the newly evolved attacks such as differential … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 7,161 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPrediction of Residual Axial Load Carrying Capacity of Reinforced Concrete (RC) Columns Subjected to Extreme Dynamic LoadsMasoud Abedini, Azrul A. Mutalib, Sudharshan N. Raman et al.The evaluation of residual axial load carrying capacity of Reinforced Concrete (RC) columns to explosion load is significant for protection of buildings. The few investigations conducted on residual axial load carrying capacity of RC columns when subjected to blast loads. Therefore, the overall aim of this research is to generate equations on the blast capacity of axially and uniaxial loaded … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 May 2017 · 8,099 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTransfer Function-Noise Modeling of the Dynamic Relationship between Botswana's Monthly Maximum Temperature and EvaporationOliver Moses, Edward Lungu, Bhagabat Prasad ParidaIn Botswana, the rate of evaporation over open water surfaces is high because the country is characterised by hot and semi arid climatic conditions. The purpose of the study is to investigate the correlation between Botswana's monthly maximum temperature and evaporation and between monthly maximum wind speed and evaporation, for the stations Gaborone, Francistown and Maun and to fit transfer … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 20 Mar 2017 · 7,604 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDeveloping and Testing Dynamic Models for HVAC Systems Using System Identification ApproachNabil Nassif, Jasmine Buford, Taher M. Abu-LebdehThis paper proposes integrated modeling and optimization methods for a chilled water HVAC system using a system identification approach. Two multiple input-single output models are developed to find the supply air temperature and fan power of the investigated chilled water air handling unit AHU. To test the proposed models, actual data are collected from existing HVAC systems.
