Axiomatic characterizations of Ptolemaic and chordal graphs [PDF]

open access: yesOpuscula Mathematica, 2023
The interval function and the induced path function are two well studied class of set functions of a connected graph having interesting properties and applications to convexity, metric graph theory. Both these functions can be framed as special instances

Internal force analysis of beams on elastic foundation using differential evolutionary optimization algorithm based on hybrid mutation technique

open access: yesTạp chí Khoa học và Công nghệ, 2023
The paper presents the Finite element method (FEM) that calculates the internal force and the displacement of beams on elastic foundation in the case of the uncertainty input parameters described in terms of the number intervals.

Some Hadamard–Fejér Type Inequalities for LR-Convex Interval-Valued Functions

open access: yesFractal and Fractional, 2021
The purpose of this study is to introduce the new class of Hermite–Hadamard inequality for LR-convex interval-valued functions known as LR-interval Hermite–Hadamard inequality, by means of pseudo-order relation ( ≤p ).

Interval parking functions

open access: yesAdvances in Applied Mathematics, 2021
Interval parking functions (IPFs) are a generalization of ordinary parking functions in which each car is willing to park only in a fixed interval of spaces. Each interval parking function can be expressed as a pair $(a,b)$, where $a$ is a parking function and $b$ is a dual parking function. We say that a pair of permutations $(x,y)$ is \emph{reachable}

Short-interval intracortical inhibition as a function of inter-stimulus interval: Three methods compared

open access: yesBrain Stimulation, 2021
Background: Short-interval intracortical inhibition (SICI), as measured by threshold-tracking as a function of inter-stimulus interval (ISI), has been proposed as a useful biomarker for amyotrophic lateral sclerosis (ALS), but its relationship to ...

Betweenness in graphs: A short survey on shortest and induced path betweenness

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
Betweenness is a universal notion present in several disciplines of mathematics. The notion of betweenness has a profound history and many pioneers like Euclid, Pasch, Hilbert have studied betweenness axiomatically.

A New Approach to Solving Linear Fractional Programming Problem with Rough Interval Coefficients in the Objective Function

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2022
This paper presents a linear fractional programming problem (LFPP) with rough interval coefficients (RICs) in the objective function. It shows that the LFPP with RICs in the objective function can be converted into a linear programming problem (LPP) with

New Hermite-Hadamard inequalities in fuzzy-interval fractional calculus via exponentially convex fuzzy interval-valued function

open access: yesAIMS Mathematics, 2021
In the present note, we develop Hermite-Hadamard type inequality and He's inequality for exponential type convex fuzzy interval-valued functions via fuzzy Riemann-Liouville fractional integral and fuzzy He's fractional integral.
