Considering unsaturation conditions of soil significantly helps to produce relatively real results. Numerical methods have been assumed as conventional methods in soil mechanics to examine soil behavior. However, the accuracy of numerical methods dramatically depends on applying the appropriate behavioral model to solve problems. One of the known elastoplastic models for unsaturated soils i...

The challenge of recognising the ward-based patient at risk of rapid deterioration is discussed frequently within the literature. As their role enables them to be in constant contact with patients, nurses are in a prime position to identify problems at an early stage with the use of systematic patient assessment. This means appropriate treatment can be initiated quickly, potentially saving the ...

Recently the stepped spillways have been used as an appropriate solution for energy dissipation. In the present study, Siahbisheh dam spillway is simulated by using Computational Fluid Dynamic (CFD), in which the Mixture method and Reynolds Stresses Model (RSM) turbulence model is used. In the first modeling series the over all steppes slope is constant. The number of the steps is increased to ...

Accurate terrain representation with appropriate preservation of important terrain characteristics, especially slope steepness is becoming more crucial and fundamental as the geographical models are getting more complex and commonly used. Based on our earlier success in Overdetermined Laplacian Partial Differential Equation (ODETLAP), which allows for compact yet accurate compression of the Dig...

In this research, experimental and numerical studies of water waves in a wave tank are analyzed how to find the optimum beach slope for simulation is also investigated. First, with aid (flap type), different amplitudes created laboratory, data generated measured by probes. Then, simulations performed Ansys Fluent industrial software. The VOF method used model two-phase flow. results compared ex...

Although anxiety disorders are common in later life, only a minority of patients receive appropriate treatment. The scarcity of clinical trials and decreasing effectiveness of current treatment modalities with advancing age, as shown by Wetherell and colleagues in this issue, argue for more clinical trials and development of age-specific psychotherapeutic techniques.

Diffusive shock acceleration theory suggests that the " universal " energy spectrum of electrons with a power-law index p ≈ 2.3, commonly used to model GRB afterglows, cannot extend below an electron lorentz factor γ e equal to the bulk lorentz factor of the blast wave multiplied by the ratio of proton and electron masses. We suggest that the electron energy distribution has a slope p < 2 below...

Rock slope instabilities are discussed in the context of decision making for risk assessment and management. Hence, the state of the slope and possible failure mechanism need to be defined first. This is done with geometrical and mechanical models for which recent developments are presented. This leads with appropriate consideration of uncertainties to risk determination and to the description ...

Firstand second-order reflection coefficients are presented for the small slope approximation. The first-order reflection coefficient is identical to the Kirchhoff, or physical optics, result, and the secondorder reflection coefficient reduces to those of perturbation theory and the Kirchhoff approximation in the appropriate limits. Numerical results are obtained for acoustic or TE-polarized el...

This work focuses on the study of the dynamic behavior and lattice size dependence of the surface root-mean-square slope in a porous thin film deposition process taking place on a triangular lattice. The simulation results indicate that the expected mean slope square reaches quickly a steady-state value and exhibits a very weak dependence with respect to lattice size variation. The simulation f...
