On Generators in Archimedean Copulas [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
This study after reviewing  construction methods of generators in Archimedean copulas (AC),  proposes several useful lemmas related with generators of AC. Then a new trigonometric Archimedean family will be shown which is based on cotangent function. The

Non-archimedean shift operators [PDF]

open access: yesP-Adic Numbers, Ultrametric Analysis, and Applications, 2010
We introduce and study non-Archimedean analogs of the operators of unilateral shift and backward shift playing crucial roles in the classical theory of nonselfadjoint operators. In particular, we find various functional models of these operators having both common and different features compared to their classical counterparts.

Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...

Stability of Various Functional Equations in Non-Archimedean Intuitionistic Fuzzy Normed Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2012
We define and study the concept of non-Archimedean intuitionistic fuzzy normed space by using the idea of t-norm and t-conorm. Furthermore, by using the non-Archimedean intuitionistic fuzzy normed space, we investigate the stability of various functional

Archimedean-type force in a cosmic dark fluid: III. Big Rip, Little Rip and Cyclic solutions

open access: yes, 2012
We analyze late-time evolution of the Universe in the framework of the self-consistent model, in which the dark matter is influenced by the Archimedean-type force proportional to the four-gradient of the dark energy pressure.

Subuniformity of harmonic mean p$$ p $$‐values

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...

Construction Archimedean tiling patterns based on soft materials from block copolymers and covalent organic frameworks

open access: yesGiant, 2023
Soft materials based on block copolymers or covalent organic frameworks (COFs) that exhibit Archimedean tiling patterns have attracted significant interest due to their potential applications in nanopatterning, nanocomposites, and shape selectivity ...

Asymptotic independence in more than two dimensions and its implications on risk management

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In extreme value theory, the presence of asymptotic independence signifies that joint extreme events across multiple variables are unlikely. Although well understood in a bivariate context, the concept remains relatively unexplored when addressing the nuances of simultaneous occurrence of extremes in higher dimensions.

Stochastic processes on non-Archimedean Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Non-Archimedean analogs of Markov quasimeasures and stochastic processes are investigated. They are used for the development of stochastic antiderivations. The non-Archimedean analog of the Itô formula is proved.
