A Comparative Study of MINLP and MPVC Formulations for Solving Complex Nonlinear Decision‐Making Problems in Aerospace Applications

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 1, Page 4-23, January/February 2026.
ABSTRACT High‐level decision‐making for dynamical systems often involves performance and safety specifications that are activated or deactivated depending on conditions related to the system state and commands. Such decision‐making problems can be naturally formulated as optimization problems where these conditional activations are regulated by ...

Generalized Energy Flow Analysis Considering Electricity Gas and Heat Subsystems in Local-Area Energy Systems Integration

open access: yesEnergies, 2017
To alleviate environmental pollution and improve the efficient use of energy, energy systems integration (ESI)—covering electric power systems, heat systems and natural gas systems—has become an important trend in energy utilization.

A model of quotient spaces

open access: yesTopological Algebra and its Applications, 2017
Let R be an open equivalence relation on a topological space E. We define on E a new equivalence relation ̃ℜ̅ by x̃ ̃ℜ̅y if the closure of the R-trajectory of x is equal to the closure of the R-trajectory of y.

Numerical verification of weak solutions of a Crocco boundary problem (typical) using an implicit second order difference scheme

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019
To verify the solution of a typical Crocco boundary problem, a numerical experiment was performed using an implicit second-order difference scheme. It is shown that a numerical solution approximates a weak solution of a typical Crocco limit problem ...

Nadler and Kannan Type Set Valued Mappings in M-Metric Spaces and an Application

open access: yesMathematics, 2019
This article intends to initiate the study of Pompeiu–Hausdorff distance induced by an M-metric. The Nadler and Kannan type fixed point theorems for set-valued mappings are also established in the said spaces.

INDEX COMPUTATION OF SOME BISINGULAR OPERATORS WITH SHIFT BY HOMOTOPY METHOD

open access: yesВестник Донского государственного технического университета, 2018
The work continues to research the insufficiently explored problem of bisingular operators with shift index. It considers new cases of index computation of the bisingular operators with indisintegrative involutive shift by the homotopy method.
