Prediction of dispersed mineralization zone in depth using frequency domain of surface geochemical data

Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...

Neural Network Application to Ship Position Estimation

The real time estimation of ship motion is considered in this paper. The problem is viewed as an estimatiod prediction problem for partially unknown systems. A neural estimator based on a dynamic recurrent neural network is considered. The model that describes the ship motion dynamics is presented, and the neural algorithm is tested and evaluated via extensive simulations. The results show that...

Domain Decomposition Analysis of Large Eddy Simulations of Ship Wakes

Simulation of turbulent fluctuations in ship wakes is one of the complex applications of large eddy simulations in computational fluid dynamics (CFD). Ship wakes simulation requires extensive computations and large amounts of computer resources. The accuracy of ship wake prediction is limited by the memory of the workstation. In this paper we present the parallel implementation of large eddy si...

Estimation of the Domain of Attraction of Free Tumor Equilibrium Point for Perturbed Tumor Immunotherapy Model

In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...
