A necessary condition for monitoring and control of a Power System (PS) is possessing a credible model of this system. The PS model for a need of dispatchers in national control centre is created in real time. An important element of such a model is a topology model. PS Topology Verification (PSTV) is an important problem in PS engineering. Often this problem is solved together with PS state es...

In this paper, we propose a methodology for training a new model of artificial neural network called the generalized radial basis function (GRBF) neural network. This model is based on generalized Gaussian distribution, which parametrizes the Gaussian distribution by adding a new parameter t. The generalized radial basis function allows different radial basis functions to be represented by upda...

In the present paper, an approach is proposed for structural topology optimization based on combination of Radial Basis Function (RBF) Level Set Method (LSM) with Isogeometric Analysis (IGA). The corresponding combined algorithm is detailed. First, in this approach, the discrete problem is formulated in Isogeometric Analysis framework. The objective function based on compliance of particular lo...

As an internal parameter of ball milling process, grinding concentration (GC) is not able to be measured directly. According to ball mill’s principle, based on radial base function (RBF) network, a soft sensor method is presented to estimate the ball mill’s GC. And a novel grey relation analysis method as a way to determine the secondary variables is proposed. Simulation results demonstrate tha...

Abstract. Some obstacles create vulnerable situations in financial market. Overcome this unexpected situation, it is essential to reform the financial market by measuring the risk of share market. This project investigates the sensitivity of radial basis functions to construct different volatility surface by radial basis function approaches to understand the risk of share market. Different type...

in this paper, an adaptive meshless method of line is applied to distribute the nodes in the spatial domain. in many cases in meshless methods, it is also necessary for the chosen nodes to have certain smoothness properties. the set of nodes is also required to satisfy certain constraints. in this paper, one of these constraints is investigated. the aim of this manuscript is the implementation ...
