Effects of air-sea drag coefficient on estimating wind stress using wind statistics

Publication Type:Academic Journal

Source(s):Oceanologia, Vol 64, Iss 3, Pp 546-552 (2022)

Abstract:This article addresses the effects of the air-sea drag coefficient on estimation of wind stress based on wind statistics. This is achieved by applying the same wind stress parameterizations chosen by Wrobel-Niedzwiecka et al. (2019) together with mean ...

Coherence Coefficient for Official Statistics.

Publication Type:Academic Journal

Source(s):Mathematics (2227-7390). Apr2022, Vol. 10 Issue 7, p1159-1159. 20p.

Abstract:One of the quality requirements in official statistics is coherence of statistical information across domains, in time, in national accounts, and internally. However, no measure of its strength is used. The concept of coherence is also met in signal pr...

LOCATION OF ZEROS OF THE POLAR DERIVATIVE OF A POLYNOMIAL.

Publication Type:Academic Journal

Source(s):Journal of Classical Analysis. 2022, Vol. 19 Issue 1, p1-12. 12p.

Abstract:In this paper, we infer bounds for the moduli of the zeros of the polar derivative of univariate complex polynomial and provide some more general results, which yields some classical bounds as special cases. [ABSTRACT FROM AUTHOR]

A BOUND FOR ZEROS OF SOLUTIONS TO A HIGHER ORDER NON-HOMOGENEOUS ODE WITH POLYNOMIAL COEFFICIENTS.

Publication Type:Academic Journal

Source(s):Differential Equations & Applications. 2021, Vol. 13 Issue 4, p405-416. 12p.

Abstract:Let Pk(z) (k = 1,2, . . ., n) and G(z) be polynomials with complex in general coefficients. The paper deals with the higher order differential equation v(n)(z)+P1(z)v(n-1)(z)+. . .+Pn(z)v(z) = G(z). We derive estimates for the sums of the zeros of solu...

NUMBER OF ZEROS OF A CERTAIN CLASS OF POLYNOMIALS IN A SPECIFIC REGION.

Publication Type:Academic Journal

Source(s):Journal of Classical Analysis. 2021, Vol. 18 Issue 1, p29-37. 9p.

Abstract:We obtain results giving bounds concerning the number of zeros of polynomials with restricted coefficients in a specific region. Our results generalize and improve several well-known results concerning the number of zeros of polynomials in certain regi...

Hybrid Whale and Genetic Algorithms with Fuzzy Values to Solve the Location Problem.

Publication Type:Academic Journal

Source(s):Mathematical Modelling of Engineering Problems. Oct2021, Vol. 8 Issue 5, p763-768. 6p.

Abstract:In this paper, a facility location model with fuzzy values parameters based on the hybrid meta-heuristic method is investigated. The proposed model uses fuzzy values to solve the installation problem. Problem hypotheses are considered fuzzy random vari...

Selkov glycolytic model with diffusion: Patterns, multistability, and stochastic transitions.

Publication Type:Academic Journal

Source(s):Mathematical Methods in the Applied Sciences. Sep2022, Vol. 45 Issue 13, p8142-8150. 9p.

Abstract:We consider a distributed variant of the Selkov mathematical model of glycolysis with diffusion and stochastic disturbances. The Turing instability zone, in which nonhomogeneous patterns are formed, is determined parametrically. Diversity of waveform s...

The association between two categorical variables measured by chi-square statistic, w index and contingency coefficient

Publication Type:Academic Journal

Source(s):Slovak Journal of Sport Science, Vol 7, Iss 2 (2022)

Abstract:This paper provides a brief overview of analysis of dependence between two categorical variables. It shows the calculation of the chi-square test, as well as its effect size using w index and the calculation of the measures of associations. DOI: https...

Reliability of the weight vector generation method of the multi-objective evolutionary algorithm and application.

Publication Type:Academic Journal

Source(s):Journal of Parallel & Distributed Computing. Nov2022, Vol. 169, p130-156. 27p.

Abstract:The decomposition-based multi-objective evolutionary algorithm first generates a set of weight vectors in advance, and it is very important to select a set of appropriate weight vectors for the decomposition-based algorithm. A variety of weight vector ...

Random statistics of OPE coefficients and Euclidean wormholes.

Publication Type:Academic Journal

Source(s):Classical & Quantum Gravity. 8/19/2021, Vol. 38 Issue 16, p1-14. 14p.

Abstract:We propose an ansatz for OPE coefficients in chaotic conformal field theories which generalizes the eigenstate thermalization hypothesis and describes any OPE coefficient involving heavy operators as a random variable with a Gaussian distribution. In t...
