Coupling Nonlinear Sigma-Matter to Yang-Mills Fields: Symmetry Breaking Patterns [PDF]
We extend the traditional formulation of Gauge Field Theory by incorporating the (non-Abelian) gauge group parameters (traditionally simple spectators) as new dynamical (nonlinear-sigma-model-type) fields.

Sustainability-driven model for predicting compressive strength in concrete structures
Over the past few decades, enhancing the sustainability of concrete structures has become a worldwide necessity. This study proposes a mathematical model for predicting compressive strength (CS), aiming to further the objective of designing sustainable ...

Outline of a Generalization and a Reinterpretation of Quantum Mechanics Recovering Objectivity
The ESR model has been recently proposed in several papers to offer a possible solution of the problems raising from the nonobjectivity of physical properties in quantum mechanics (QM) (mainly the objectification problem of the quantum theory of ...

Analysis and computations for a model of quasi-static deformation of a thinning sheet arising in superplastic forming [PDF]
We consider a mathematical model for the quasi-static deformation of a thinning sheet. The model couples a first-order equation for the thickness of the sheet to a prescribed curvature equation for the displacement of the sheet.

The Standard Model as a noncommutative geometry: the low energy regime
We render a thorough, physicist's account of the formulation of the Standard Model (SM) of particle physics within the framework of noncommutative differential geometry (NCG). We work in Minkowski spacetime rather than in Euclidean space.

Constructing Parsimonious Analytic Models for Dynamic Systems via Symbolic Regression
Developing mathematical models of dynamic systems is central to many disciplines of engineering and science. Models facilitate simulations, analysis of the system's behavior, decision making and design of automatic control algorithms.

Design and Kinematics Analysis of the Wearable Lower Limb Exoskeleton
With the increasing proportion of people with lower limb dysfunction in the population, lower limb exoskeleton, mainly in the form of physical assisted therapy, has become a research hotspot in the field of rehabilitation. In this study, a wearable lower

Numerical simulation of stratified flows usingOpenFOAM package
The paper is devoted to construction of a numerical model and computations of continuously stratified fluid flows in field of external mass forces accounting for dissipative factors, viscosity and diffusion. Mathematical model is based on the fundamental

Modelling rapid mass movements using the shallow water equations in Cartesian coordinates [PDF]
We propose a new method to model rapid mass movements on complex topography using the shallow water equations in Cartesian coordinates. These equations are the widely used standard approximation for the flow of water in rivers and shallow lakes, but the ...

Accommodating Taste and Scale Heterogeneity for Front-Seat Passenger’ Choice of Seat Belt Usage
There is growing interest in implementation of the mixed model to account for heterogeneity across population observations. However, it has been argued that the assumption of independent and identically distributed (i.i.d) error terms might not be ...
