Literature ReviewOpen accessIn the abstractSocial Cohesion: Its Meaning and ComplexitiesItumeleng Mekoa, Dauda BusariThe concept Social cohesion is relative and a somewhat difficult concept to define. Many scholars have offered varying degree of definitions but the main challenge noticed in the definition, is the multiple definitions based on individual scholar’s orientation or ideology. Another problem poised by these definitions of the concept is that of multi-level and multi-dimensional nature. Contemporary scholars of social … …Journal of Social Sciences, Vol. 14, Issue 1 · 27 Mar 2018 · 9,919 accessesView PDFCite
Review ArticleOpen accessIn the abstractProject HARPRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The HARP project, abbreviated from the High Altitude Project, was considered a joint project of the United States Department of Defense and Canada's Department of Defense, originally designed to study low-cost re-entry vehicles. Generally, such projects used rocket launchers to launch missiles, costly and often inefficient. The HARP project used a non-rocket space launch method based on a very large … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 7 Nov 2017 · 19,808 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Optimal Implementation of a Generator of SinusoidSouhila Boudjema, Kaddour SaouchiThe embedded systems occupy a place increasingly important in our daily life. In recent years much of research it is focused on the miniaturization of the various electronic devices. In this study we present the architecture of a digital generator of frequency based on trigonometrically algorithm to obtain sample high frequencies. We treat a comparative study between various processors CORDIC: … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 17 Sep 2015 · 6,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Defense Mechanism for Differential Power Analysis Attack in AESJ. Vijaya, M. RajaramIn modern wireless communication world, the security of data transfer has been the most challenging task. In embedded system, AES is the most extensively used cryptographic algorithm in practice. But its functionality has been disrupted by the DPA attack. There have been several countermeasures to tackle those attacks, but this study proposes variably a new measure to defend this DPA … …Journal of Computer Science, Vol. 11, Issue 2 · 1 Sep 2014 · 7,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE VOCALIZATION MECHANISM OF THE FLORIDA MANATEE (TRICHECHUS MANATUS LATIROSTRIS)Charles J. Grossman, Richard E. Hamilton, Martine De Wit et al.The mechanism by which Florida manatees produce vocalizations is unknown. Anatomically, the laryngeal region in manatees lacks clearly defined vocal folds. Initially we developed a method to visualize the entire manatee upper respiratory system. We then forced air through fresh necropsied manatee larynxes and generated artificial vocalizations which closely duplicated the normal vocalizations produced by live manatees, both in fundamental … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 8,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractReconfigurable Hardware Architecture for Network Intrusion Detection SystemA. Kaleel Rahuman, G. AthishaIntrusion rule processing in reconfigurable hardware enables intrusion detection and prevention. The use of reconfigurable hardware for network security applications has great strides as Field Programmable Gate Array (FPGA) devices have provided larger and faster resources. This proposes architecture called “BV-TCAM” is presented, which is implemented for an FPGA-based Network Intrusion Detection Systems (NIDS). The BV-TCAM architecture combines the Ternary … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractTonal Language Speech Compression Based on a Bitrate Scalable Multi-Pulse Based Code Excited Linear Prediction CoderSuphattharachai ChomphanProblem statement: Speech compression is an important issue in the modern digital speech communication. The functionality of bitrates scalability also plays significant role, since the capacity of communication system varies all the time. When considering tonal speech, such as Thai, tone plays important role on the naturalness and the intelligibility of the speech, it must be treated appropriately. Therefore these … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo Optimization Methods to Determine the Rate Constants of a Complex Chemical Reaction Using FORTRAN and MATLABAbdel-Latif Aboul Seoud, Lamiaa A.M. AbdallahProblem statement: For chemical reactions, the determination of the rate constants is both very difficult and a time consuming process. The aim of this research was to develop computer programs for determining the rate constants for the general form of any complex reaction at a certain temperature. The development of such program can be very helpful in the control of … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,050 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of Microelectromechanical System Capacitive Shunt SwitchesHaslina Jaafar, Othman Sidek, Azman Miskam, Shukri KorakkottilProblem statement: RF MEMS switch is one of MEMS area that creates devices that have great potential to improve the performance of communication circuits and systems and enables the realization of micro size mechanical switches embedded in electronics devices. The low voltage switches are necessary due to their compatibility of standard IC technology in RF application and microelectronics systems.
