Outline of a Generalization and a Reinterpretation of Quantum Mechanics Recovering Objectivity

open access: yes, 2015
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 ...

Numerical simulation of stratified flows usingOpenFOAM package

open access: yesТруды Института системного программирования РАН, 2018
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

Design and Kinematics Analysis of the Wearable Lower Limb Exoskeleton

open access: yesJixie chuandong, 2023
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

Accommodating Taste and Scale Heterogeneity for Front-Seat Passenger’ Choice of Seat Belt Usage

open access: yesMathematics, 2021
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 ...

A New Mathematical Model for Assembly Line Worker Assignment and Balancing

open access: yes, 2019
Aim of assembly line balancing is to assign the product parts to the workstations that constitute the assembly line. Worker assignment problem is a new problem variety in assembly lines that typically is met in different situations in which the workforce

The effect of the incidence function on the existence of backward bifurcation

open access: yesLetters in Biomathematics, 2016
In modelling, the dynamics of infectious disease, the choice of the specific mathematical formulation of disease transmission (i.e. the incidence function) is one of the initial assumptions to be made.

The Standard Model as a noncommutative geometry: the low energy regime

open access: yes, 1997
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.

An iterative compositional model for subsurface multiphase flow [PDF]

open access: yes, 1994
The governing equations describing multiphase flow with multicomponent solute transport may be cast in a number of forms. While mathematically equivalent, the numerical models based on each formulation differ in flexibility and efficiency.
