A semilinear beam equation with nonconstant loads

Nonlinear Analysis: Theory, Methods & Applications, 1997
Summary: We investigate multiplicity of solutions \(u(x,t)\) for a piecewise linear perturbation \(-(bu^+ -au^-)\) of the one-dimensional beam operator \(u_{tt} +u_{xxxx}\) under Dirichlet boundary condition on the interval \((-\pi/2, \pi/2)\) and periodic condition on the variable \(t\).

Cauchy problem for equations with loadings on surfaces

Ukrainian Mathematical Journal, 1988
The authors consider differential equations which include not only values of a function in the points of some region but also its values in the points of submanifolds of smaller dimension. A theorem about correctness of the Cauchy problem for a class of such equations is proved.

A reappraisal of the Engelund bed load equation

Hydrological Sciences Journal, 1994
Abstract Many bed load transport equations have been developed from differing standpoints. The Engelund equation has been selected for scrutiny since, although it accords well with experimental data in general, it has limitations under conditions of high bed load transport rates.

Parallelization of the linear load flow equations

2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002
The Jacobi iterative method is a simple mathematical tool of great effectiveness to solve lineal equation systems such as those used in electric network models. In this paper it is proposed that the application of this method for the solution of load flow equations, using an appropriate technique of decomposition of the electric network in partial nets

Bifurcation analysis of the load flow equations

1980 19th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1980
The bifurcation of the load flow equation of a power transmission network with PV buses and lossless lines is studied. This analysis has application in the development of numerical continuation methods.

On the integral equation method for buckling loads

Applied Mathematics and Computation, 1975
An initial value method for the integral equation of the column is presented for determining the buckling load of columns. The differential equation of the column is reduced to a Fredholm integral equation. An initial value problem is derived for this integral equation, which is reduced to a set of ordinary differential equations with prescribed ...

Reaeration Equations and Waste‐Load Allocations

Journal of Environmental Engineering, 1991
This technical note estimates the possible effects on calculated critical dissolved oxygen deficits of using reaeration equations as compared to measured reaeration rates. Differences between observed and calculated reaeration coefficients can produce changes of about 30 percent in the calculated critical dissolved oxygen deficits.
