چکیده
We introduce and analyze a space-time least-squares method associated with the unsteady Navier–Stokes system. Weak solution in two dimensional case regular three are considered. From any initial guess, we construct minimizing sequence for functional which converges strongly to of After finite number iterations related value viscosity coefficient, convergence is quadratic. Numerical experiments within support our analysis. This globally convergent approach damped Newton method.

Least – Squares Method For Estimating Diffusion Coefficient
Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...

Determining the diffusion coefficient based on the solution of the linear inverse problem of the parameter estimation by using the Least-square method is presented. A set of temperature measurements at a single sensor location inside the heat conducting body is required. The corresponding direct problem will be solved by an application of the heat fundamental solution.
متن کاملA Meshless Method Based on Least-squares Approach for Steady- and Unsteady-state Heat Conduction Problems
The meshless method based on the least-squares approach, the meshless weighted leastsquares (MWLS) method, is extended to solve conduction heat transfer problems. The MWLS formulation is first established for steady-state problems and then extended to unsteady-state problems with time-stepping schemes. Theoretical analysis and numerical examples indicate that larger time steps can be used in th...

متن کاملSpace-time Least-squares Finite-element Method for Shallow-water Equations
In this paper, a space-time least-squares finite-element method for the 2D nonlinear shallow-water equations (SWE) is developed. The method can easily handle complex geometry, bed slope (source term), and radiation boundary condition without any special treatment. Other advantages of the method include: high order approximations in space and time can easily be employed, no upwind scheme is need...
