Quantitative assessment of working conditions in the workplace
Engineering Management in Production and Services, 2020 Indicators, different in terms of nature and grading scales, are used to recognise hazardous and harmful factors that affect human health. However, no single methodology is available for their assessment, and the variety of qualimetric assessment methods

Port-Estimation of a Shape Second-Order Parameter
Revstat Statistical Journal, 2014 In this paper we study, under a semi-parametric framework and for heavy right tails, a class of location invariant estimators of a shape second-order parameter, ruling the rate of convergence of the normalised sequence of maximum values to a non ...

A Direct Prediction of the Shape Parameter in the Collocation Method of Solving Poisson Equation
Mathematics, 2022 In this paper, we totally discard the traditional trial-and-error algorithms of choosing the acceptable shape parameter c in the multiquadrics −c2+∥x∥2 when dealing with differential equations, for example, the Poisson equation, with the RBF collocation ...
