Influence of boundary constraints on the appearance of asymmetrical equilibrium states in circular plates under normal pressure

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
Unsymmetrical buckling of nonuniform circular plates with elastically restrained edge and subjected to normal pressure is studied in this paper. The unsymmetric part of the solution is sought in terms of multiples of the harmonics of the angular ...

Grouting Treatment of Water and Mud Inrush in Fully Weathered Granite Tunnel: A Case Study

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
When mountain tunnel passes through completely weathered granite strata, water and mud inrush is easy to occur, causing casualties and economic losses. Grouting is a common and effective treatment method for water and mud inrush disaster. The current existing researches focus on theoretical analysis, numerical simulation, and laboratory test, and the ...

Edge Jump Distance Graphs [PDF]

open access: yes, 2015
The concept of edge jump between graphs and distance between graphs was introduced by Gary Chartrand et al. in [5]. A graph H is obtained from a graph G by an edge jump if G contains four distinct vertices u, v, w, and x such that uv belongs to  E(G)

A Global Description of the Positive Solutions of Sublinear Second-Order Discrete Boundary Value Problems

open access: yesAdvances in Difference Equations, 2009
Let T∈ℕ be an integer with T>1, 𝕋:={1,…,T}, 𝕋^:={0,1,…,T+1}. We consider boundary value problems of nonlinear second-order difference equations of the form Δ2u(t−1)+λa(t)f(u(t)

A Note on Stability of a Linear Functional Equation of Second Order Connected with the Fibonacci Numbers and Lucas Sequences

open access: yesJournal of Inequalities and Applications, 2010
We prove the Hyers-Ulam stability of a second-order linear functional equation in single variable (with constant coefficients) that is connected with the Fibonacci numbers and Lucas sequences.

Note on the q-Extension of Barnes' Type Multiple Euler Polynomials

open access: yesJournal of Inequalities and Applications, 2009
We construct the q-Euler numbers and polynomials of higher order, which are related to Barnes' type multiple Euler polynomials. We also derive many properties and formulae for our q-Euler polynomials of higher order by using the multiple integral ...
