Research ArticleOpen accessIn the abstractA Comparative Performance Analysis of Multiple-Input Multiple-Output using MATLAB with Zero Forcing and Minimum Mean Square Error EqualizersBara'u Gafai Najashi, Tan XiaohengProblem statement: Multiple-Input Multiple-Output systems (MIMO) were regarded as one of the most promising technologies in field of wireless communication. Generally considered as one of the several forms of smart antenna technology, it offers considerable increase in data throughput and link range without additional bandwidth or transmit power. The general idea involves the use of several antennas at the transmitter … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 8,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractColored Image Compression Using Gradient Adjustment Prediction Based WaveletMuna Faik Hanoon Al-SammraieProblem statement: Uncompressed graphics, audio and video data require considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive digital audio, image and video (multimedia) based web applications, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,312 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocation Based Throughput Maximization Routing in Energy Constrained Mobile Ad-hoc NetworkV. Sumathy, P. Narayanasamy, R. PrabhuIn wireless Ad-hoc network, power consumption becomes an important issue due to limited battery power. One of the reasons for energy expenditure in this network is irregularly distributed node pattern, which impose large interference range in certain area. To maximize the lifetime of ad-hoc mobile network, the power consumption rate of each node must be evenly distributed and the over … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstructing Longest Lifetime Route in Mobile Ad-hoc NetworksFredrick Mtenzi, Yingyu WanA mobile ad hoc network (MANET) is an autonomous system consisting of mobile hosts connected by wireless links. Every host can move in any direction at any speed and time. This leads to a dynamic topology as hosts move constantly. MANET broadcast messages to each hosts, the transmission of one host can be heard by all hosts in its communication … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Identification of Leishmania Species in Patient with Cutaneous Leishmaniasis in an Endemic Area of Fars Province, Southern IranVahid Rahmanian, Nader Sharifi, Zahra Kargar Jahromi et al.The Cutaneous Leishmaniasis (CL) contains a range of factors, which provide different patterns of transmission that make it difficult to control. The aim of this study was to identify the different species of Leishmania in the Jahrom district of Fars province, southern Iran. This descriptive study was done on CL suspected cases who were referential to the Reference of Jahrom … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 2 Apr 2021 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis and Synthesis of Mechanisms with Bars and Gears Used in Robots and ManipulatorsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Bars and gears are used everywhere today, but a wide range of uses is robotics and mechatronics. Since ancient times, automations and mechanization have been used with mechanisms consisting of chains of bars and gears. These were obviously used for the purpose of transmitting the movement and its transformation, that is to say, as a mechanical transmission. Gear and bar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Silico Characterization and Motif Election of Neurotoxins from Snake VenomMahmudul Hasan, Ziaul Faruque Joy, Elius Hossain Bhuiyan, Md Shiful IslamSnake venom is a mixture of many biological components. Snakes usually use their venomic armory to tackle different prey and predators in adverse natural world. Among various components of the snake venom, neurotoxins play an important role in exerting effect by blocking the neuromuscular transmission through selective binding to muscle nicotinic Acetyl-Choline Receptors (nAChR). A set of 30 reference protein … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 2 Mar 2015 · 7,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractEDGE PRESERVED IMAGE COMPRESSION USING EXTENDED SHEARLET TRANSFORMS. Thayammal, D. SelvathiThe motivation of the proposed compression method is to reduce the bit rate for image transmission or memory requirement for image storage while maintaining image quality. The edges are one of the prominent features in an image and they are essential for maintaining image quality. JPEG compression standards like JPEG98 and JPEG2000 produce visual artifacts in reconstructed image at low … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,046 accessesView PDFCite
