Research ArticleOpen accessAll words, across the recordReduction of PAPR by Using Clipping and Filtering for Different Modulation SchemesArun Kumar, Manisha GuptaOrthogonal Frequency Division Multiplexing (OFDM) is one of the most advanced technologies for high speed data access in mobile communication. It’s significantly increases the capacity, data-rate etc. but one of its disadvantage is high Peak Average Power Ratio (PAPR) which reduce the performance of transmitter amplifier. In this study, PAPR is reduced by using a clipping and filtering technique for … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 13 Feb 2016 · 8,360 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAN ALGORITHM FOR MINING USABLE RULES USING A HOLISTIC SWARM BASED APPROACHVeenu Mangat, Renu VigEvolutionary algorithms are capable of finding near optimal solutions to problems which are intractable to solve using conventional methods. One such problem is to accurately classify patients using rule mining methodology while controlling the size of output rules. A massive amount of data pertaining to medicine is generated and recorded daily. Uncovering useful knowledge and assisting decision makers in the … …Journal of Computer Science, Vol. 10, Issue 4 · 9 Dec 2013 · 6,667 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAN EFFICIENT POWER REDUCTION TECHNIQUE IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM USING TONE RESERVATIONV. Nandalal, S. SophiaIn a basic communication system, the data’s are modulated onto a single carrier frequency. The available bandwidth is then totally occupied by each symbol. This kind of system can lead to Inter-Symbol-Interference (ISI) in case of frequency selective fading. The basic idea of Orthogonal Frequency Division Multiplexing (OFDM) is to divide the available spectrum into several orthogonal sub channels so … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,471 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModified Power Save Model for Better Energy Efficiency and Reduced Packet LatencyNarendran Rajagopalan, C. MalaDevices constituting wireless ad-hoc networks generally operate in battery power, energy efficiency is a critical research issue. IEEE 802.11 Power Save Mode is a standard recommended for energy efficient operation of wireless ad-hoc networks. When there is no data to transfer, energy is still utilized by IEEE 802.11 PSM during the ATIM window. With this work, an attempt is made … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 3 · 29 Aug 2012 · 8,312 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Influence of Garcinia kola Seed on Sexual Behavior and Testis Physiology in Wistar RatsJonah Sydney Aprioku, Victor Nwachukwu, Blessing Ukamaka Okeke et al.Garcina kola seed is believed by some to enhance male sexual performance but existing scientific data show divergent results. In this study, the sexual and reproductive influence of ethanol (70%) seed extract of G. kola was evaluated in Wistar rats. Adult male rats were gavaged with 0, 50, 100, 200 or 300 mg kg-1 day-1 of extract for 30 days … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 25 Apr 2018 · 13,804 accessesView PDFCite
Research NotesOpen accessAll words, across the recordA Proposed Framework for Outsourcing and Secure Encrypted Data on OpenStack Object Storage (Swift)Hala Albaroodi, Selvakumar Manickam, Mohammed AnbarDespite the numerous potential benefits of Open Source Cloud Computing (OSCC) in several industrial and academic-oriented environments, OSCC could be also associated with some risks. However, which a proper awareness to the cloud consumers or organisations, these risks can be clearly identify and avoided. OpenStack Swift security can provide a greater understanding of how OpenStack Swift functions and what types … …Journal of Computer Science, Vol. 11, Issue 3 · 14 May 2015 · 7,004 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOdds to Quicken Reporting Already Delayed Cases: Acquired Immune Deficiency Syndrome Incidences are IllustratedRamalingam ShanmugamDelayed reporting in a medical system complicates efforts to estimate the number of cases that occurred in a time period. A case in point is the government’s difficulty to estimate the number of Acquired Immune Deficiency Syndrome (AIDS) cases. The reporting delays are not intentional but are ongoing due to changing Federal regulations or medical definitions of the case like … …International Journal of Research in Nursing, Vol. 4, Issue 1 · 1 Apr 2013 · 6,415 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Beneficial Effect of Asiaticoside on Experimental Neuropathy in Diabetic RatsChonlathip Thipkaew, Jintanaporn Wattanathorn, Supaporn MuchimapuraThough diabetic neuropathy produces high impact on quality of life, annual cost and morbidities, the therapeutic efficacy is still not in a satisfaction level. Based on the crucial role of oxidative stress on the pathophysiology of diabetic neuropathy and the improvement of this condition induced by antioxidant, we hypothesized that asiaticoside, a substance possessing antioxidant activity, could provide beneficial effect. … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 31 Aug 2012 · 7,051 accessesView PDFCite
