The Need for a Multiscale Modeling Framework
ences is that of a “field,” which, together with appropriate mathematical operations on fields, is used to express the physical conservation laws of nature, such as conservation of mass, momentum, charge, etc. Fields were first introduced by the great 19th-century British scientist Michael Faraday to represent the intensity and direction of the force experienced by a small charged particle in t...
متن کاملMini-symposium B1 Multiscale Modeling and Simulations
During the last years, we have developed nonadiabatic excited state dynamics methods based on Trajectory Surface Hopping/Linear Response Time-Dependent Density Functional Theory (TSH/LRTDDFT) and real time propagation TDDFT (PT-TDDFT) based Ehrenfest dynamics and have combined them with mixed quantum mechanical/ molecular mechanical (QM/MM) simulations to study nonadiabatic processes in complex...
متن کاملan investigation about the appropriate stochastic modeling framework for agricultural insurance pricing
با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...
An Assessment of Wind Erosion Schemes in Dust Emission Simulations over the Middle East
Extended abstract 1- INTRODUCTION Atmospheric aerosols, solid and liquid particles in the atmosphere, play a crucial role in the atmospheric radiation equilibrium. These particles have an influence on the scattering and absorption of short wavelength radiation, and on the other hand, affect radiation absorption and emission in long wavelengths. Dust particles are among the importan...
متن کاملModeling the Martian dust cycle 2. Multiannual radia- tively active dust transport simulations
Multi-annual dust transport simulations have been performed using a Mars general circulation model containing a dust transport scheme which responds to changes in the atmospheric state. If the dust transport is ‘radiatively active’ the atmospheric state also responds to changes in the dust distribution. This paper examines the suspended dust distribution obtained using different lifting paramet...
