Research ArticleOpen accessEvery word in the titleThree Dimensional Multidirectional Geographical IP Traceback: Direction Ratio Sampling AlgorithmA. Rajiv Kannan, K. Duraiswamy, K. SangeethaProblem statement: An important and challenging problem is that of tracing DOS/DDOS attack source. IP traceback is the process of identifying the actual source(s) of attack packets, So that the attackers can be held accountable as also in mitigating them, either by isolating the attack sources or by filtering packets for away from the victim. Several IP traceback schemes have … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,238 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of the Effective Factors on Threshing loss, Damaged Grains Percent and Material Other than Grain to Grain Ratio on an Auto Head Feed Threshing UnitE. Askari Asli-Ardeh, Y. Abbaspour-GilandehProblem Statement: Regarding to considerable production of rice crop in Iran, study and investigation about optimization of different stages of this product processing seems necessary. The threshing of rice is a process which must be accomplished desirability. Approach: In this study, the effective factors effects on threshing loss, damaged grain percent and Material Other than Grain (MOG) to grain ratio, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,914 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancing P300 Component by Spectral Power Ratio Principal Components for a Single Trial Brain-Computer InterfaceS. Andrews, Ramaswamy Palaniappan, Andrew Teoh, Loo chu KiongHere we present a novel approach to detect P300 wave in single trial Visual Event Related Potential (VERP) signals using improved principal component analysis to enable a faster brain-computer interface (BCI) design. In the process, the principal components (PCs) are selected using novel methods, namely spectral power ratio (SPR) and sandwich spectral power ratio (SSPR). We set out to assess … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,884 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhanced Variable Splitting Ratio Algorithm for Effective Load Balancing in MPLS NetworksG. Murugesan, A. M. Natarajan, C. VenkateshFast load balancing is of the highest importance to utilize the resources effectively and improve the performance of the Multi Protocol Label Switching (MPLS) enabled Internet Protocol (IP) networks. Load balancing splits a part of traffic called splitting ratio from the maximum loaded path in to minimum loaded path. One very strong constrain in balancing the load is the tradeoff … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,345 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdaptive Update Policy for Proactive Management of Deadline Miss Ratio and Data Freshness in Real-Time Database ModelsSanjay Tanwani, Ashwani K. RamaniImportant applications, like e-commerce, online stock trading, traffic control demand real-time data services. Conventional database perform poor at these applications. A database for real-time data services has to support timing constraints and temporal consistency in addition to supporting characteristics of a conventional database system. In other words, it is desirable to execute transactions within its deadline using updated data reflecting … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,211 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRandomized Response Procedure for the Estimation of the Population Ratio using Ranked Set SamplingAgustin Santiago, Carlos N. Bouza, J. Maclovio Sautto, Amer Ibrahim Al-OmariIn this study we deal with the estimation of the population ratio, when a Randomized Response (RR) procedure is used for collecting responses and Ranked Set Sampling (RSS) is the selection method. The variances of the suggested estimators are calculated. Comparisons between different estimators are presented. …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 27 Apr 2016 · 7,400 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Projects Sharing Ratios under Musharakah Financing: A Repeated Game Theoretical Approach Using an Output versus a Proposed Effort Based ContractAdil Elfakir, Mohamed TkiouatIn this research, we provide a game theoretical approach of new projects financed under musharakah contracts using two types of contracts. The first type is effort based. It compensates the agent for the effort provided regardless of market conditions. The other type of contract is output based where the agent compensation is based solely on output realized. Our intuition is, … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 8 Oct 2015 · 7,427 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModules Over Rings of Small Characteristics and Maximality of Data Hiding ratio in CPTE SchemesPhan Trung Huy, Cheonshik Kim, Nguyen Hai ThanhIntroduced CPT scheme as a block-based hiding scheme based on the ring of the integers modulo 2r, which permits to embed r = ⌊log2(k+1)⌋ secret bits in F by changing at most two entries, while the highest number of secret bits in any CPT-based schemes is MSDR2 = ⌊log2(1+k (k+1)/2)⌋, approximately 2r-1. This ratio can be reached approximately in our … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,711 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePeak to Average Power Ratio Reduction of Orthogonal Frequency Division Multiplexing System with a Significant Low ComplexityMahamod Ismail, J. S. Mandeep, Montadar Abas Taher, M. T. IslamThe Orthogonal Frequency Division Multiplexing (OFDM) has been widely used in many applications in the last decade. It provides good benefits compared to the single carrier systems. However, it has a bad property represented by the high-output Peak to Average Power Ratio (PAPR) which is considered as its major problem. There are many techniques to reduce the PAPR values such … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 20 Dec 2012 · 6,594 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePeak-to-Average Power Ratio Reduction Using Active Constellation Extension-Projection Onto Convex Sets Combined with Particle Swarm Optimization Added to Space Time Bloc Coding in Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing SystemAhmed Ouqour, Abdelhamid Louliej, Younes Jabrane et al.When generated Orthogonal Frequency Division Multiplexing (OFDM) signal is transmitted through a number of antennas in order to achieve diversity or cap any gain (higher transmission rate) then it is known as Multiple Input Multiple Output (MIMO)-OFDM. The full form of MIMO is multi input and multi output where signals are transmitted via multiple antennas instead of only one antenna … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 6,995 accessesView PDFCite
