Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF HIGH EFFICIENCY LOW DENSITY PARITY-CHECK CODE DECODER FOR LOW POWER APPLICATIONSM. Revathy, R. SaravananIn this study, we propose a low power, high efficient Low Density Parity-Check Code (LDPC) Decoder Architecture for error detection and correction applications. LDPC codes have been adopted in latest wireless standards such as satellite and mobile communications since they possess superior error-detecting and correcting capabilities. As technology scales, memory devices become larger and more powerful and low power consumption … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 30 Jan 2014 · 6,888 accessesView PDFCite

BalachandranA picture or image is worth a thousand words. It is very much pertinent to the field of image processing. In the recent years, much advancement in VLSI technologies has triggered the abundant availability of powerful processors in the market. With the prices of RAM are having come down, the databases could be used to store information on the about … …Journal of Computer Science, Vol. 10, Issue 2 · 13 Nov 2013 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Features of Rodoretto Valley Deep-Seated Gravitational Slope DeformationsMaria Gabriella Forno, Andrea Lingua, Stefano Lo Russo, Glenda TaddiaA new, detailed survey of the Rodoretto Valley (Western Alps, Italy) has been conducted resulting in the production of a new morphological and quaternary geological map of the area. The authors used the innovative Solid (True) Ortho-Photo (STOP) technology integrated with navigation sensors (Global Navigation Satellite System-GNSS/Inertial Measurement Unit-IMU). This state-of-the-art procedure has demonstrated several operational advantages during both the … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 9 Feb 2013 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractTunability Performance of Reflectarrays Based on Non-Linear Material PropertiesM. Y. Ismail, M. Hashim DahriLimited phase range and narrower bandwidth are the main performance limitations of reflectarray antennas for high gain applications which result in the performance to be restricted particularly in satellite and earth observatory systems. This study provides a thorough investigation on the tunability performance of reflectarrays designed in X-band frequency range using different non-linear dielectric substrates. An investigation of phase agility … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 6 Feb 2013 · 7,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Spatial Distribution of Apis Dorsata Host Plants Using an Integrated Geographical Information System-Remote Sensing ApproachIzzat F. Ibrahim, Siva K. Balasundram, Nur-Ashikin P. Abdullah et al.Apis dorsata is one of the important honeybee species in tropical and subtropical regions that forages on various plants including herbs, grasses, forest trees and plantation trees. However, information on the spatial distribution of various pollen sources of Apis dorsata is still lacking. This study aimed at mapping the spatial distribution of the major honeybee plants that serve as pollen … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 20 Sep 2012 · 8,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Multi Spectral Band Image Compression using Discrete Wavelet TransformR. Kousalyadevi, S. S. RamakrishnanProblem statement: Efficient and effective utilization of transmission bandwidth and storage capacity have been a core area of research for remote sensing images. Hence image compression is required for multi-band satellite imagery. In addition, image quality is also an important factor after compression and reconstruction. Approach: In this investigation, the discrete wavelet transform is used to compress the Landsat5 agriculture … …Journal of Computer Science, Vol. 8, Issue 5 · 6 Mar 2012 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractGPS Ionospheric Total Electron Content and Scintillation Measurements during the October 2003 Magnetic StormMohammad Awad Momani, Takialddin A. Al Smadi, Farouq M. Al Taweel, Khaldoon A. GhaidanProblem Statement: Ionospheric scintillations, cause significant effects on satellite signals for communication and navigation in equatorial region and polar regions mainly during sever magnetic storms periods. This phenomenon is not fully understood due to few studies performed. The study investigates variability of Total Electron Content (TEC) and ionospheric scintillation during October 2003 magnetic storm over Antarctica using ground based GPS … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,514 accessesView PDFCite
