Similarity Measures of q-Rung Orthopair Fuzzy Sets Based on Cosine Function and Their Applications
Mathematics, 2019 In this article, we propose another form of ten similarity measures by considering the function of membership degree, non-membership degree, and indeterminacy membership degree between the q-ROFSs on the basis of the traditional cosine similarity ...

Similarity Measures of Spherical Fuzzy Sets Based on Cosine Function and Their Applications
IEEE Access, 2019 In this paper, we defined ten similarity measures between spherical fuzzy sets (SFSs) based on the cosine function by considering the degree of positive-membership, degree of neutral-membership, degree of non-membership and degree of refusual-membership ...

A pseudorandom bit generator based on hyperbolic cosine function [PDF]
ITM Web of Conferences, 2022 In the literature, little attention is paid to devising and analyzing novel one dimensional chaotic mappings. In our previous efforts, we have tried fold, translation & scale on arctangent function & sigmoid function respectively, which brings good ...

Almost-distribution cosine functions and integrated cosine functions [PDF]
Studia Mathematica, 2005 Operator valued cosine functions were introduced in the 1950s to solve well-posed abstract second order Cauchy problems. Later, in analogy to operator semigroup theory, the strong continuity conditions were weakened to be able to treat also ill-posed problems.

Extended Wang sum and associated products.
PLoS ONE, 2022 The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions.

Bounded Cosine Functions Close to Continuous Scalar Bounded Cosine Functions [PDF]
Integral Equations and Operator Theory, 2016 Let $(C(t))\_{t \in R}$ be a cosine function in a unital Banach algebra. We show that if $sup\_{t\in R}\Vert C(t)-cos(t)\Vert \textless{} 2$ for some continuous scalar bounded cosine function $(c(t))\_{t\in \R},$ then the closed subalgebra generated by $(C(t))\_{t\in R}$ is isomorphic to $\C^k$ for some positive integer $k.$ If, further, $sup\_{t\in \R}

Digital shaping methods for nuclear pulse signal based on cosine function
He jishu, 2023 BackgroundCosine function shaping (or cos shaping) is used to digitally shape nuclear pulse signals, as the shaping method is simple and has high operability and flexibility.PurposeThis study aims to explore different cosine shaping methods of nuclear ...

Integrated cosine functions [PDF]
International Journal of Mathematics and Mathematical Sciences, 1994 In order to the second order Cauchy problem (CP2) : x″(t) = Ax(t), x(0) = x ∈ D(An), x″(0) = y ∈ D(Am) on a Banach space, Arendt and Kellermann recently introduced the integrated cosine function. This paper is concerned with its basic theory, which contain some properties, perturbation and approximation theorems, the relationship to analytic integrated

Demonstratio Mathematica, 2022 In this article, by virtue of expansions of two finite products of finitely many square sums, with the aid of series expansions of composite functions of (hyperbolic) sine and cosine functions with inverse sine and cosine functions, and in the light of ...
