El-Labban, M. Abdelaziz, Essam R.I. MahmoudThe present study aims to improve the surface hardness of carbon steel by application of laser surface melting of effective conditions. The travelling speed of laser beam during this treatment is one of the important treatment conditions. This study aims to investigate the effect of laser surface melting with different beam speeds on macro and microstructure as well as the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 2 Jan 2014 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractANALYSIS AND SOLUTION FOR MULTI-BAND ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING ULTRA WIDE BAND SYSTEM IN REAL ENVIRONMENT FOR VEHICLE TO INFRASTRUCTURE APPLICATIONSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.Many researches in the world deal with driving on the road to ensure optimum safety. In this context, several telecommunication technologies are often used to connect the vehicles via continuous wireless communication with the infrastructure, exchange data and information relevant to increase overall road safety and enable cooperative traffic management. These systems are not reliable for all situations and the … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Design of Blade for Small Horizontal-Axis Wind Turbine with Low Wind Speed OperationParamet Pathike, Thanad Katpradit, Pradit Terdtoon, Phrut SakulchangsatjataiIn Thailand, the average wind speed throughout the country is comparatively low for normally-available wind turbine. Designing of a new blade suitable for applications in the average wind speed of 3-7 m sec-1 is, thus, a main objective of this study. High torque has to be obtained properly to generate electricity. In order to design and evaluate performance, our mechanical … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Probabilistic Relay in Ad Hoc On-demand Distance Vector and Ad Hoc On-demand Multipath Distance Vector Under Highly Dynamic EnvironmentsRadityo Anggoro, Teruaki Kitasuka, Ryoji Nakamura, Masayoshi AritsugiVehicular Ad hoc Networks (VANETs) are a specific class of Mobile Ad hoc Networks (MANETs). Since vehicles tend to move in a high speed, the network topology is rapidly changed. Thus vehicle’s connectivity problem is one of the interesting issues in VANETs. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extended version of ad hoc on-demand distance vector (AODV). … …Journal of Computer Science, Vol. 9, Issue 7 · 22 Jun 2013 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Closed Loop LCL-T Resonant DC-to-DC Converter Using Low Cost Embedded ControllerM. Annamalai, M. Vijaya KumarThe aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 6 Feb 2013 · 7,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Multidictionary Based Text CompressionM. Baritha Begum, Y. VenkataramaniThe amount of digital contents grows at a faster speed as a result does the demand for communicate them. On the other hand, the amount of storage and bandwidth increases at a slower rate. Thus powerful and efficient compression methods are required. The repetition of words and phrases cause the reordered text much more compressible than the original text. On … …Journal of Computer Science, Vol. 8, Issue 12 · 8 Nov 2012 · 6,946 accessesView PDFCite
