Hermite-Hadamard and Simpson’s type of inequalities for first and second ordered derivatives using product of (h1, h2, s)-convex and m-convex function

Sabir Yasin, Zurni Omar, Masnita Misiran

In this paper: This article is dedicated to find the extensions for Hermite-Hadamard (H-H) and Simpson’s type of inequalities. By combining multiple existing convex functions by placing specific restrictions on them...

Interval-valued picture fuzzy sets in UP-algebras

Nattacha Lapo, Pimwaree Kankaew, Sunisa Yuphaphin, Ronnason Chinram, Aiyared Iampan

In this paper: We used the notion of interval-valued picture fuzzy sets (IvPFSs) in UP-algebras to introduce the eight new notions of IvPFSs. We also discuss about how the eight new notions of IvPFSs in UP-algebras...

Solving Robin condition using a method based on integral equation

Mohsen Aghaeiboorkheili

In this paper: In this paper, Robin boundary value problem is solved numerically with an integral equations’ based method. The suggested method has been compared with other existing methods or exact solution to appr...

Can you feel the algebraic structure? Quaternion and finite rings in the service of patterns and weaving

Refael Barkan, Shai Gul, Aviv Hochman, Eliyahu Matzri

In this paper: Artists frequently create symmetrical patterns, but disregard the mathematical structure that allows their formation. We here seek to expose this underlying construct and afford new ways of using math...

Some integral inequalities for Hadamard fractional moments of continuous random variables

Mohamed Houas

In this paper: Using Hadamard fractional integral operator, some new integral inequalities for the Hadamard fractional moments of continuous random variables are obtained.

Modified public key cryptosystem based on distance and geometry area in triangles

Maxrizal, Baiq Desy Aniska Prayanti

In this paper: Public key cryptosystems using commutative algebra are not safe from quantum algorithm attacks. For this reason, experts have developed non-commutative algebra applied to geometry-based public key cry...
