Research ArticleOpen accessEvery word in the titleAn Optimal Rate Adjustment Algorithm for Medium Access Control Protocol in 802.11 Multi Hop Ad Hoc NetworksT. Ravichandran, K. SaravananProblem statement: Medium Access Control (MAC) protocol plays an important role in providing a fair and efficient allocation of limited bandwidth in wireless LANs. In IEEE 802.11 standard protocol, data rate selection is not specified. Rate control is the process of switching data rates dynamically based on channel conditions, with the target of selecting the rate that will provide the … …Journal of Computer Science, Vol. 8, Issue 7 · 9 Jun 2012 · 7,030 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRelationship between Selected Properties of Starchy Vegetables on Grating and Slicing Production RateLok Chung Yee, M.K. Siti Mazlina, B.T. Hang TuahPrediction on the output of grating and slicing of starchy vegetables are important prior to design or develop the particular food plant. The production rate of grating and slicing products could be affected by the properties of starchy vegetables. In this study, two selected properties which hardness and moisture content are studied. Hardness of selected starchy vegetables was measured using … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 6 Jun 2012 · 7,669 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMeasures of Explained Variation and the Base-Rate Problem for Logistic RegressionDinesh Sharma, Dan McGee, B.M. Golam KibriaProblem statement: Logistic regression, perhaps the most frequently used regression model after the General Linear Model (GLM), is extensively used in the field of medical science to analyze prognostic factors in studies of dichotomous outcomes. Unlike the GLM, many different proposals have been made to measure the explained variation in logistic regression analysis. One of the limitations of these measures … …Current Research in Biostatistics, Vol. 2, Issue 1 · 25 Feb 2012 · 8,584 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Approach to Defend Against Distributed Denial of Service Attacks Using an Adaptive Spin Lock Rate Control MechanismR. Anurekha, K. Duraiswamy, A. Viswanathan et al.Problem statement: The last decade has seen many prominent Distributed Denial of Service (DDoS) attacks on high profile webservers. In this study, we deal with DDoS attacks by proposing a dynamic reactive defense system using an adaptive Spin Lock Rate control (D3SLR). D3SLR identifies malicious traffic flow towards a target system based on the volume of traffic flowing towards the … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 7,066 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of Electromagnetic Radiation and Specific Absorption Rate of Mobile Phones with Fractional Human Head Models via Green's FunctionsNookala Srinivasa Rao, G. R. Babu, P. V.S. SrinivasProblem statement: Electromagnetic Radiation from mobile hand set is identified as one of the side effects for increasing rate of brain tumor. Due to this reason, Mobile phone industries are attentive towards safety issues of human health. Specific Absorption Rate is one of the important parameter while modeling the radiation effect on human head. Brain material with homogeneity is treated … …Journal of Computer Science, Vol. 7, Issue 8 · 16 Jul 2011 · 6,701 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy Parametric Deduction for Material Removal Rate OptimizationTian-Syung LanProblem statement: A general optimization scheme without equipment operations for CNC (computer numerical control) finish turning is deemed to be necessarily developed. Approach: In this study, four parameters (cutting depth, feed rate, speed, tool nose runoff) with three levels (low, medium, high) were considered to optimize the Material Removal Rate (MRR) based on L9(34) orthogonal array. Twenty-seven fuzzy control rules … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,243 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWeed Detection over Between-Row of Sugarcane Fields Using Machine Vision with Shadow Robustness Technique for Variable Rate Herbicide ApplicatorA. Muangkasem, S. Thainimit, R. Keinprasit, T. IsshikiProblem statement: Uniformly herbicide rate is used as a conventional practice in Thailand for controlling weeds in sugarcane fields. Since weeds usually grow in certain areas with non-uniformly distribution, uniform herbicide rate approach is not suitable and non-sustainable agricultural technique both in terms of economic an environmental aspect. To address these issues, Variable Herbicide Rate (VHR) was introduced. The VHR … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,238 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRate Effect on Pullout Behavior of Steel Fibers Embedded in Very-High Strength ConcreteTaher Abu-Lebdeh, Sameer Hamoush, Brian ZornigProblem statement: Rate dependence of the newly developed Very-High-Strength-Concrete (VHSC) composites has received little or no attention so far. Approach: In this research, the bond-slip mechanisms of four types of steel fibers embedded in VHSC matrices were investigated through single-fiber pullout tests with the loading rates and matrix strengths are the primary variables. This study presented the experimental results of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,448 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleScalp Induction Rate Responses to Cytokinins on Proliferating Shoot-Tips of Banana Cultivars (Musa spp.)Siamak Shirani, Meon Sariah, Wahab Zakaria, Mahmood MaziahProblem statement: The effect of cytokinins on scalp induction from in vitro propagating shoot tips of different banana (Musa spp. AAA and AAB) cultivars was studied. Approach: Proliferation rate increased with an increasing concentration of Benzyl Amino Purine (BAP) up to 22.2 µM while, lower level of BAP (11.1 µM) increased scalp induction. Results: Kinetin induced a lower number of … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,447 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTwo Optimization Methods to Determine the Rate Constants of a Complex Chemical Reaction Using FORTRAN and MATLABAbdel-Latif Aboul Seoud, Lamiaa A.M. AbdallahProblem statement: For chemical reactions, the determination of the rate constants is both very difficult and a time consuming process. The aim of this research was to develop computer programs for determining the rate constants for the general form of any complex reaction at a certain temperature.
