Research ArticleOpen accessIn the keywordsOn Odds Generalized Exponential-Power Lomax DistributionSalwa Mahmoud AssarA new distribution, called odds generalized exponential-power Lomax distribution is suggested for modeling lifetime data. Some structural properties of the new distribution including; quantiles, Rényi entropy, moments and distribution of order statistics are provided. The model parameters of the new distribution are estimated by the maximum likelihood method. Finally, applications to two real data sets are analyzed to illustrate the … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 12 Jun 2018 · 7,567 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModified 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 accessIn the keywordsIs Air Pollution Controlled Enough? “Tapered Probabilities” AnswerRamalingam ShanmugamAir pollution is dangerous sespecially to the residents in cities, as it causes lung, heart, or respiratory illness. Public health professionals ponder whether the air pollution is significantly controilled. The amount of existing air pollution is measurable, but not its regulated level, which is therefore as a parameter in a novel manner in this article. However, there is no suitable … …Current Research in Medicine, Vol. 8, Issue 1 · 6 Nov 2017 · 12,733 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAN 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 accessIn the keywordsAn Optimal Path Management Strategy in Mobile Ad Hoc Network Using Fuzzy and Rough Set TheoryP. Seethalakshmi, M. Joseph Auxilius Jude, G. RajendranProblem statement: Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically forms a network. Most of the existing ad-hoc routing algorithms select the shortest path using various resources. However the selected path may not consider all the network parameters and this would result in link instability in the network. The problems with existing methods are … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA BIVARIATE PROBABILITY MODEL TO IDENTIFY "HONESTY" VERSUS "CHEATING" IN ECONOMIC SURVEYS: XENOPHOBIA IS ILLUSTRATEDRamalingam ShanmugamMaking successful policies for manufacturing or globalized business sectors require "honest" answers by the respondents in the surveys. When some respondents cheat in their answers to the questions in a survey for a variety of reasons, the survey results become useless. Currently, there is no appropriate probability model to address this phenomenon "cheating" in a survey. An efficient methodology is … …American Journal of Economics and Business Administration, Vol. 6, Issue 1 · 18 Jun 2014 · 6,849 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAlzheimer’s Disease Prognosis is Captured by a Down-Upsized Incidence Poisson DistributionRamalingam ShanmugamAlzeimer disease is a daunting nightmare to both the medical and families of the patients. Tireless efforts are made by the medical researchers to treat Alzheimer’s patients. The Alzhiemer patients’ data provides clues about its prognosis and they can be identifies when the data are analyzed and understood correctly. The data analysis is a first step in the path to … …Current Research in Medicine, Vol. 4, Issue 2 · 4 Sep 2013 · 6,926 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIs Cancer Recurrence Postponed By a Treatment? A New Model AnswersRamalingam ShanmugamDuring a treatment period of a cancer patient, the medical team ponders over a question: Is patient’s cancer recurrence significantly postponed by the medication, even if the illness is not completely cured? This question could be answered with data evidence if the data are analyzed with an appropriate model and a suitable methodology. A scanning of the literature reveals that … …Current Research in Medicine, Vol. 4, Issue 1 · 26 Mar 2013 · 6,887 accessesView PDFCite

Research ArticleOpen accessIn the abstractEnhanced Lifetime Maximization Using Metaheuristics-Based Unequal Clustering With Routing Protocol on Wireless Sensor NetworksN. E. Kanaghadhara, R. SubanThe Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors that monitor environmental or physical factors such as sound, pressure, or temperature, and pass the information directly through the network to a sink or central location. Clustering and routing are essential in WSNs to optimize their longevity, scalability, and efficiency. Clustering includes grouping Sensor Nodes (SN) into clusters, each … …Journal of Computer Science, Vol. 22, Issue 7 · 21 Jul 2026 · 682 accessesView PDFCite
