A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...

There are various methods for the analysis of the interactional behavior of the surrounding land, using the lining structure which is the most common method of deigning lining structure tools for the static loads by using the hyper static methods. In recent years, there has been a question that depicts whether this method provides the best results in designing the tunnel structure or not.Due to...

In this work some quantitative structure activity relationship models were developed for prediction of three bioenvironmental parameters of 28 volatile organic compounds, which are used in assessing the behavior of pollutants in soil. These parameters are; half-life, non dimensional effective degradation rate constant and effective Péclet number in two type of soil. The most effective descripto...

wide range of planar structures in new technologies has attracted special consideration. in this research vibration behavior of plates with non-linear edges is investigated by means of finite difference (fd) method. for this issue, classical and analytical solutions for plates with linear edges were analyzed and mutual equations, needed for numerical calculation were extracted. by expanding the...

This study aims to examine the internal meso-mechanical behaviour of cement-stabilised macadams subjected loading damage following water immersion. By constructing a numerical analysis model, mechanism water-immersion weakening macadam material and micro-mechanical specimen were analysed. The simulation results compared with laboratory test data. peak stress error was 2.414%, whereas maximum in...

For small tension the response of a solid to an applied stress is given by Hooke’s law. Outside this linear regime relation between and strain no longer universal at present there satisfactory insight on how connect for disordered materials stress-strain microscopic properties system. Here we use atomistic computer simulations establish connection case silicate glasses containing alkali modifie...
