Generalized harmonic functions on trees: Universality and frequent universality [PDF]
Journal of Mathematical Analysis and Applications, 2021 Recently, harmonic functions and frequently universal harmonic functions on a tree $T$ have been studied, taking values on a separable Fr chet space $E$ over the field $\mathbb{C}$ or $\mathbb{R}$. In the present paper, we allow the functions to take values in a vector space $E$ over a rather general field $\mathbb{F}$.

Universal portfolios generated by rational functions [PDF]
ITM Web of Conferences, 2021 The f -divergence of Csiszar is defined for a non-negative convex function on the positive axis. A pseudo f -divergence can be defined for a convex function not satisfying the usual requirements. A rational function where both the numerator and the denominator are non-integer polynomials will be used to generate universal portfolios.

GENERALIZED UNIVERSALITY FOR TMD DISTRIBUTION FUNCTIONS [PDF]
International Journal of Modern Physics: Conference Series, 2012 Azimuthal asymmetries in high-energy processes, most pronounced showing up in combination with single or double (transverse) spin asymmetries, can be understood with the help of transverse momentum dependent (TMD) parton distribution and fragmentation functions.

Signature of A-Within-B-From-D/G Sliding Window System [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2019 In this study, we have proposed a model of the sliding window coherent system in case of multiple failures. The considered model consists of G linearly required multi-state elements and G number of parallel elements in A-within-B-from-D/G for each multi ...

Efficient harmony search optimization for preventive-maintenance-planning for nuclear power systems
International Journal for Simulation and Multidisciplinary Design Optimization, 2014 This paper combines the universal generating function UGF with harmony search (HSO) meta-heuristic optimization method to solve a preventive maintenance (PM) problem for series-parallel system. In this work, we consider the situation where system and its

Short-term reliability evaluation for power stations by using
Journal of Modern Power Systems and Clean Energy, 2013 A short-term reliability evaluation is used for power stations, where each power generating unit is presented by a multi-state Markov model. The main obstacle for reliability evaluation in such a case is a “curse of dimensionality”—a
