چکیده
Abstract One of the promising methods early warning a tsunami is obtaining data wave heights based on numerical solution inverse problem by using truncated singular value decomposition method as variant least-squares method. The considered within framework linear theory propagation. technique proposed allows one to avoid inevitable instability solution. It possible choose most informative directions for placement observation stations, which analysis energy transfer spatial modes generated each right vector. As it has turned out, best location stations closely related intense distribution energy. significant advantages approach presented possibility, without additional calculations propagation from reconstructed source, obtain at points there are no observations but associated when calculating matrix direct operator. implementation actual event Chilean Illapel Tsunami September 16, 2015, presented.

Designing a New Model for Evaluating the Maintenance System
The previous studies about the maintenance systems were dealt with defining the evaluation criteria, grouping them, and using different techniques for evaluating. The main problem is that maintenance subsystems and the relationship between and within them in order to a reliable evaluation have never been identified before.The contribution of this study is realizing the four maintenance su...

متن کاملThe method of radial basis functions for the solution of nonlinear Fredholm integral equations system.
In this paper, An effective and simple numerical method is proposed for solving systems of integral equations using radial basis functions (RBFs). We present an algorithm based on interpolation by radial basis functions including multiquadratics (MQs), using Legendre-Gauss-Lobatto nodes and weights. Also a theorem is proved for convergence of the algorithm. Some numerical examples are presented...
