Research ArticleOpen accessPhrase in the titleMinimization of ℓ2-Norm of the KSOR OperatorA. I. Alzaki, I. K. YoussefWe consider the problem of minimizing the ℓ2-norm of the KSOR operator when solving a linear systems of the form AX = b where, A = I +B (TJ = -B, is the Jacobi iteration matrix), B is skew symmetric matrix. Based on the eigenvalue functional relations given for the KSOR method, we find optimal values of the relaxation parameter … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 8 Jan 2013 · 7,083 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Phenomenon of Nonzero Norm of Long-Term Changes in the Total Water Supply in River BasinsViktor V. Kovalenko, Ekaterina V. GaidukovaIn hydrology, the norm of changes in water supply is considered to be equal to zero, under long-term averaging. This assumption allows for calculating and mapping the long-term evaporation rates linked by the water balance with maps of precipitation and river runoff. The phenomenon of nonzero norm of change of the total water supply is provided using the effect of … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 27 May 2015 · 6,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleError Vector Normalized Adaptive Algorithm Applied to Adaptive Noise Canceller and System IdentificationZayed RamadanProblem statement: This study introduced a variable step-size Least Mean-Square (LMS) algorithm in which the step-size is dependent on the Euclidian vector norm of the system output error. The error vector includes the last L values of the error, where L is a parameter to be chosen properly together with other parameters in the proposed algorithm to achieve a trade-off … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,208 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNorm Divergence Opportunity Structure and Utilization of Self-Employed Immigrants' QualificationsShahamak Rezaei, Marco GoliProblem statement: Denmark experienced one of the most successful periods of its economy in 2004-2008, with a tremendous reduction of 77% in unemployment. Due to the structural challenges with regard to the labor market the utilization of immigrants’ qualifications has come up to the surface of political and societal debate in Denmark. The focus of this study was challenges to … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 7,832 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSemantic Refinement of Multi-meaning Words by T-normsF. Sadeghi, H. Khosravi, E. EslamiIn this paper we consider a multi-meaning word which appears in a sentence together with some connected words. To refine the meaning of this multi-meaning word, we propose a method based on T-norms which are reasonable mathematical models of logical conjunction operator in fuzzy logic. The preliminary results derived from a prepared corpus are encouraging. …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,416 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTwister Generator of Random Normal Numbers by Box-Muller ModelAleksei F. Deon, Yulian A. MenyaevTwisting generators of the pseudorandom normal variables can use uniform random sequences as a basis. However, such technique could provide poor quality result in cases where the original sequences have insufficient uniformity or skipping of random values. This work offers a new approach for creating the random normal variables using the Box-Muller model as a basis together with the twisting … …Journal of Computer Science, Vol. 16, Issue 1 · 10 Jan 2020 · 11,556 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNormative Data Obtained in Testing the Sense of Hearing in Kangal Shepherd DogsMustafa Koçkaya, Yusuf Özşensoy, Hakan MuratSense of hearing is of crucial importance for dogs to perform their duties. There is no study to determine the reference latency intervals of dogs' sense of hearing. The aim of this study is to identify normative data that can be used as the reference interval for the wave latencies I, III and V at 80 dB with respect to … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 3 · 22 Aug 2019 · 7,350 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStatistical Size and Power of Eight Normality Tests in Presence of GARCH (1 1) ErrorsJulio César Alonso, Daniela EstradaIn this work, we assess the power and size of eight normality tests underthe assumption that errors follow a GARCH (1, 1) process by using MonteCarlo simulations. Four results stand out. First, the presence of a GARCH(1, 1) process increases the probability of making type I error. Second, Pearsonnormality test is recommended if it is assumed that errors follow a … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 11 Feb 2019 · 6,992 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConstruction and Application of a Statistical Test for Coefficient of Variation on Normal DistributionsSolly Matshonisa Seeletse, Gezani Richman MiyambuIn this study a novel statistical test is derived for the Coefficient of Variation (CV) under normal distributions. This is a newly derived test with value to engineering sciences in aspects of production of accurate items. The CV can measure the precision of a measuring instrument, among other applications. In order to determine instrument reliability, start by generating measures using … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 11 Nov 2017 · 7,850 accessesView PDFCite
