Effect of non-stationary external forces on vibrations of composite pipelines conveying fluid [PDF]

open access: yesE3S Web of Conferences, 2023
The effect of non-stationary external forces on the vibration of pipelines made of composite materials is investigated in the paper. A mathematical model of composite pipeline vibration is developed, considering the viscosity properties of the structure ...

On the Volterra integral equation with weakly singular kernel [PDF]

open access: yesMathematica Bohemica, 2006
Summary: We give sufficient conditions for the existence of at least one integrable solution of equation \(x(t)=f(t)+\int _{0}^{t} K(t,s)g(s,x(s))\,ds\). Our assumptions and proofs are expressed in terms of measures of noncompactness.

Numerical solvability of a class of Volterra-Hammerstein integral equations with noncompact kernels

open access: yesJournal of Applied Mathematics, 2005
We study the numerical solvability of a class of nonlinear weakly singular integral equations of Volterra-Hammerstein type with noncompact kernels. We obtain existence and uniqueness results and analyze the product integration methods for these equations

On operators induced by weakly 2-singular kernels [PDF]

open access: yesCzechoslovak Mathematical Journal, 1995
It is shown that a kernel \(K(x,y)= L(x,y)/| x-y|^{1/2}\) for \(x\neq y\) in \([0,1]\) defines a \((q,2)\)-summing operator on \(L_\infty(0,1)\) for any \(q>2\) provided that \(\sup_x| L(x,\cdot)|\in L_{2,1}(0,1)\).
