Various Regularization Functions in System Identification Problems for Solids
نویسنده
چکیده
This paper presents various regularization functions, which are employed to overcome instabilities of system identification problems. Since a regularization function define the solution space of a given problem, it should well represent both mathematical and physical characteristics of the original problem. The regularization function can be derived from the integrability condition of the solution in conjunction with physical consideration. The L1-norm as well as L2-norm of system parameters is used to define the regularity functions. Various types of regularization functions and their characteristics are discussed.

Applying Legendre Wavelet Method with Regularization for a Class of Singular Boundary Value Problems
In this paper Legendre wavelet bases have been used for finding approximate solutions to singular boundary value problems arising in physiology. When the number of basis functions are increased the algebraic system of equations would be ill-conditioned (because of the singularity), to overcome this for large $M$, we use some kind of Tikhonov regularization. Examples from applied sciences are pr...
متن کاملImplementation of Sinc-Galerkin on Parabolic Inverse problem with unknown boundary condition
The determination of an unknown boundary condition, in a nonlinaer inverse diffusion problem is considered. For solving these ill-posed inverse problems, Galerkin method based on Sinc basis functions for space and time will be used. To solve the system of linear equation, a noise is imposed and Tikhonove regularization is applied. By using a sensor located at a point in the domain of $x$, say $...

In the present article an energy distribution function of heterogeneous solid was estimated. Energy distribution function is an important characterization for heterogeneous adsorbent. An overall adsorption quantity for a heterogeneous solid is usually expressed by a first kind of Fredholm equation, which contains unknown distribution function and local adsorption isotherm as a kernel. The calcu...

This paper introduces the Hamiltonian system into quasi-static problems of 3D viscoelastic solids. Based on the principle of elastic-viscoelastic correspondence, the problem of solving partial differential equations is reduced to finding general eigensolutions of the dual equations, and all analytical fundamental eigensolutions and their corresponding Jordan forms are derived. After the symplec...
متن کاملA General New Algorithm for Regulaization of Singular Integrals in Three-Dimensional Boundary Elemnts
In this paper an algorithm is presented for the regularization of singular integrals with any degrees of singularity, which may be employed in all three-dimensional problems analyzed by Boundary Elements. The integrals in Boundary Integrals Equations are inherently singular. For example, one can mention the integrals confronted in potential problems to evaluate the flow or the gradient of the f...
