in this paper, a higher order continuum model is presented based on the cosserat continuum theory in 3d numerical simulation of shear band localization. as the classical continuum models suffer from the pathological mesh-dependence in strain softening models, the governing equations are regularized by adding the rotational degrees-of-freedom to conventional degrees-of-freedom. the fundamental r...

Flood zonation mapping is one of the priorities for the soil and water management, which Remote Sensing (RS) capabilities are very applicable to this issue. The main objective of this research was study of accuracy of the Object oriented and Pixel based methods for flood zonation mapping in the Taleghan River basin. Therefore, the Sentinel 2A satellite image of the study area classified using s...

The self-developed finite element program on return mapping algorithm is used for the simulation of true tunnel with C++ language, while the finite element program is embedded into differential evolution algorithm to incorporate rock mechanics parameters. Applying to Line 1 of Dalian Metro, inversion parameters and true parameters are found to be close, which indicates the superiority and good ...

We present a novel technique for efficient coding of texture to be mapped on 3D landscapes. The technique enables to stream the data across the network using a back-channel. The use of Wavelet and Discrete Cosine Transforms is investigated and compared. This technology has been proposed has a tool for the emerging MPEG-4 standard.

In this paper a numerical approach of the elasto-plastic problem with mixed hardening in the plane stress state, within the classical constitutive framework of small deformation, is proposed. In the formalized problem, the non-zero normal component of the strain (namely, the component in the direction perpendicular to the plane of stress) is considered to be compatible with the plane stress. We...

Many open problems involve the search for a mapping that is used by an algorithm solving an MDP. Useful mappings are often from the state set to some other set. Examples include representation discovery (a mapping to a feature space) and skill discovery (a mapping to skill termination probabilities). Different mappings result in algorithms achieving varying expected returns. In this paper we pr...

emissivity mapping of the earth’s surface is the prerequisite to thermal remote sensing. a precise determinationof a surface's temperature is dependent upon the availability of precise emissivity data for that surface. the presentstudy area is a part of sugarcane plantation fields in the west part of khuzestan province. in this work, temperatureemissivity separation algorithm (tes) was applied ...
