Truss geometry and topology optimization with global stability constraints

open access: yesStructural And Multidisciplinary Optimization, 2020
In this paper, we introduce geometry optimization into an existing topology optimization workflow for truss structures with global stability constraints, assuming a linear buckling analysis.

Stability of Global Monopoles Revisited [PDF]

open access: yesPhysical Review Letters, 2000
We analyze the stability of global O(3) monopoles in the infinite cutoff (or scalar mass) limit. We obtain the perturbation equations and prove that the spherically symmetric solution is classically stable (or neutrally stable) to axially symmetric, square integrable, or power-law decay perturbations.

Global Stability of Delayed SARS-CoV-2 and HTLV-I Coinfection Models within a Host

open access: yesMathematics, 2022
The aim of the present paper is to formulate two new mathematical models to describe the co-dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human T-cell lymphotropic virus type-I (HTLV-I) in a host.

Global stability in a networked SIR epidemic model

open access: yesApplied Mathematics Letters, 2020
A graph Laplacian reaction–diffusion system is introduced to a networked SIR epidemic model. By the means of Lyapunov function, we show that the endemic equilibrium is globally asymptotically stable if the basic reproduction number is greater than 1 ...

Dynamical Behavior of a Fractional Order Model for Within-Host SARS-CoV-2

open access: yesMathematics, 2022
The prime objective of the current study is to propose a novel mathematical framework under the fractional-order derivative, which describes the complex within-host behavior of SARS-CoV-2 by taking into account the effects of memory and carrier.

Global Properties of Cytokine-Enhanced HIV-1 Dynamics Model with Adaptive Immunity and Distributed Delays

open access: yesComputation, 2023
In this paper, we study a model that enhances our understanding of cytokine-influenced HIV-1 infection. The impact of adaptive immune response (cytotoxic T lymphocytes (CTLs) and antibodies) and time delay on HIV-1 infection is included.

Stability analysis of steel frames according to Eurocode 3 [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2019
In the paper, the qualitative and quantitative comparison of EC3 methods to verify the global stability of the structure is presented. The steel portal frame subjected to varied loads is considered.

Almost Global Stochastic Stability [PDF]

open access: yes, 2005
We develop a method to prove almost global stability of stochastic differential equations in the sense that almost every initial point (with respect to the Lebesgue measure) is asymptotically attracted to the origin with unit probability.

Global banking stability in the shadow of Covid-19 outbreak

open access: yesJournal of international financial markets, institutions, and money, 2021
The ongoing Covid-19 pandemic has been exerting negative effects on several economies in 2020. Therefore, it is of paramount importance to examine the impact of this pandemic on the global banking stability and to assess any potential recovery signals ...

Bumpless Transfer of Uncertain Switched System and Its Application to Turbofan Engines

open access: yesEnergies, 2021
Nonlinear control problems in turbofan engines are challenging. No single nonlinear controller can achieve desired control effects in a full flight envelope, but in the case of multiple controllers, there exist problems in the bumpless transfer between ...
