Calculation of the deflection of an arched truss with suspended elements depending on the number of panels

Structural Mechanics of Engineering Constructions and Buildings, 2020
The aim of the work - to propose a scheme and analytical calculation of a statically definable planar truss with a suspended lower belt. Methods. The formula for the dependence of the deflection of the truss under the action of a uniform load on the ...

Uniform Approximation to the Solution of a Singularly Perturbed Boundary Value Problem with an Initial Jump

Mathematics, 2020
In this study, a third-order linear integro-differential equation with a small parameter at two higher derivatives was considered. An asymptotic expansion of the solution to the boundary value problem for the considered equation is constructed by ...

Second order phase field asymptotics for multi-component systems [PDF]

, 2006
An asymptotic analysis of a phase field model for solidification in multicomponent alloy systems is presented. In the limit of vanishing interface thickness the related sharp interface model is approximated to second order by taking a non-constant ...

Justification of Direct Scheme for Asymptotic Solving Three-Tempo Linear-Quadratic Control Problems under Weak Nonlinear Perturbations

Axioms, 2022
The paper deals with an application of the direct scheme method, consisting of immediately substituting a postulated asymptotic solution into a problem condition and determining a series of control problems for finding asymptotics terms, for asymptotics ...

Upper bound on the characters of the symmetric groups for balanced Young diagrams and a generalized Frobenius formula [PDF]

, 2008
We study asymptotics of an irreducible representation of the symmetric group Sn corresponding to a balanced Young diagram λ (a Young diagram with at most View the MathML source rows and columns for some fixed constant C) in the limit as n tends to ...

Projector Approach to Constructing Asymptotic Solution of Initial Value Problems for Singularly Perturbed Systems in Critical Case

Axioms, 2019
Under some conditions, an asymptotic solution containing boundary functions was constructed in a paper by Vasil’eva and Butuzov (Differ. Uravn. 1970, 6(4), 650−664 (in Russian); English transl.: Differential Equations 1971, 6, 499−510 ...

Weyl asymptotics for perturbations of Morse potential and connections to the Riemann zeta function

Concrete Operators, 2023
Let N(T;V)N\left(T;\hspace{0.33em}V) denote the number of eigenvalues of the Schrödinger operator −y″+Vy-{y}^{^{\prime\prime} }+Vy with absolute value less than TT. This article studies the Weyl asymptotics of perturbations of the Schrödinger operator −y″

Asymptotic Idempotency

2007 IEEE International Fuzzy Systems Conference, 2007
This paper deals with aggregation operators. A new class of aggregation operators, called asymptotically idempotent, is introduced. A generalization of the basic notion of aggregation operator is provided, with an in-depth discussion of the notion of idempotency.
