The theory of diffusion processes in solids has achieved significant results in recent decades, but the development of methods for calculating diffusion in a multicomponent thermodynamic system is still an urgent task. P...

This paper presents an elementary model of a crystal and its thermodynamic equilibrium state. It was shownthat the thermodynamic characteristics of the crystal at this state are described by the Gibbs grand thermodynamic...

We prove an equilibrium existence theorem for economies with externalities, general types of non-convexities in the production sector, and infinitely many commodities. The consumption sets, the preferences of the consume...

Reinforcement learning (RL) is a widely used learning paradigm that has shown significant successes in solving many hard AI problems including mastering real-time strategy games, autonomous car driving, and LLM model ali...

Abstract Robot hands have been developing during the last few decades. There are many mechanical structures and analytical methods for different hands. But many tough problems still limit robot hands to apply in homelike...

Na Amazônia o cromo é empregado principalmente na indústria de couro e de madeira, sendo responsável por vários problemas de saúde porque é tóxico para os seres vivos. A remoção de cromo de efluentes industriai...

Efficiently solving the user equilibrium traffic assignment problem with elastic demand (UE-TAPED) for transportation networks is a critical problem for transportation studies. Most existing UE-TAPED algorithms are desig...

In response to the existing problems in the temperature monitoring of boreholes in high-temperature fire areas of open-pit coal mines, this study proposed an intelligent temperature monitoring and early warning system by...

Anticipating labour supply and demand remains relevant due to significant transformations in the labor market caused by socio-economic, demographic, and technological factors. In addition, infrastructure destruction, job...

This study investigates a fractional partial differential equation in the field of mathematical biology. The Bernoulli (G'⁄G)-expansion method is applied to solve this class of fractional-order nonlinear differential e...

This study introduces Felis Catus Optimization (FCO), a novel nature‑inspired metaheuristic algorithm modeled on the ecological and adaptive behavioral dynamics of urban domestic cats. FCO divides its population into e...

In this paper, using Gibbs grand thermodynamic potential, kinetic tensors of electrical and thermal conductivity generalized equations known in non-equilibrium thermodynamics have been proven. These tensors determine cal...

Introduction According to modern scholars (N. Maslova, B. Astafiev), one of the important reasons for the global planetary crisis, including modern educational system in particular, is violation of the conformity of natu...

The problems of modeling the stress-deformed state of erosion or corrosion-worn rectilinear sections and the ball-shaped bends of pipeline systems are proposed to solve in a cylindrical coordinate system. For this purpos...

Since its inception, the DMRG method has been a very powerful tool for the calculation of physical properties of low-dimensional strongly correlated systems. It has been adapted to obtain dynamical properties and to cons...

One of the problems which has plagued those attempting to predict the behavior of capital markets is the absence of a body of positive microeconomic theory dealing with conditions of risk. Although many useful insights c...

This paper considers the problem faced by a seller who has a single object to sell to one of several possible buyers, when the seller has imperfect information about how much the buyers might be willing to pay for the ob...

The author points out the necessity of a regulating plan for the city of Cordoba which considers the problems that have come forth as a result of the concentration of administrative and commercial activities, in addition...

In general equilibrium the production possibility sets and consumer preferences are convex. The reason for this assumption resides in two problems which arise when it is not made. Instituto de Investigaciones Económicas

Fil: De Ángelis, Jésica. Universidad Nacional de Quilmes. Departamento de Economía y Administración; Argentina. La problemática de la restricción externa (RE) puede asociarse a una tasa de crecimiento compatible co...

Este trabajo consta de tres partes, que en principio parecen ser bastante diferentes, pero tienen como hilo conductor la toma de decisiones que debe realizar una persona, un grupo de personas, un equipo, etc. Cada una ...

It is suggested that analysis by means of "indifference functions" shall be extended to election among investment spaces; and the way in which that technique Could be developed to be applied to such problems is outlined ...

In the type of keynesian analysis the productive capacity is a constant, and therefore the problems derived from obtaining an equilibrium between the global supply (offer) and the global demand, even when they may be dif...

The relationship between co-integration and error correction models, first suggested in Granger (1981), is here extended and used to develop estimation procedures, tests, and empirical examples. If each element of a vect...
