Analysis of a Mathematical Model of Marital Satisfaction

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A large number of marriages end in divorce. In this paper, we present a model for the emotional state of a couple based on bilinear ordinary differential equations. We study the effect of changes of each individual's self‐emotional state on the couple's state.

On r-factors with components containing specified vertices in a torus

AKCE International Journal of Graphs and Combinatorics
Let T be a graph obtained by taking the Cartesian product of n cycles of even lengths [Formula: see text]. It is known that for any subset of k vertices of T with [Formula: see text] there exists a 2-factor in T where each cycle contains exactly one of ...

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

Applying Cech rough closure theory to binary hypercube graphs [PDF]

Mathematics and Computational Sciences
The present study examines hypercube graphs through the lens of Čech rough closure theory (ČRCT). Leveraging the binary representation and inherent symmetry of hypercubes, we introduce a closure-based approach for modelling uncertainty and vagueness in ...

Hypercube matrix computation task [PDF]

A major objective of the Hypercube Matrix Computation effort at the Jet Propulsion Laboratory (JPL) is to investigate the applicability of a parallel computing architecture to the solution of large-scale electromagnetic scattering problems.

Unravelling vicious circles of land use competition and food insecurity in agropastoral rangelands

People and Nature, EarlyView.
Abstract In many regions of the world, the adoption of new livelihood strategies that compete with traditional strategies is one driver of competition over land, resulting in unforeseen impacts on the livelihoods of land users and accelerating land degradation. One example is the Borana Zone in southern Ethiopia, where the expansion of crop cultivation

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation

Polymer Composites, EarlyView.
Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

Dynamical simulations of QCD at finite temperature with a truncated perfect action

, 2006
The Hypercube operator determines a variant of the approximate, truncated perfect fermion action. In this pilot study we are going to report on first experiences in dynamical QCD simulations with the Hypercube fermions.

Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.
