We study the scattering properties of a cloud particles. The particles are spherical, close to incident wavelength in size, have high albedo, and randomly packed 20% volume density. show, using both numerically exact methods for solving Maxwell equations radiative-transfer-approximation methods, that converge after about ten million system. After that, backward-scattered system should estimate ...

The magnetic field dependence of qce, the cage escape yield of radicals generated by photoelectron transfer between Ru(bpy)3zt and methylviologen (MV++) was investigated for a series of solvent mixtures of increasing viscosity, obtained by adding ethylene glycol (EGLY) to H20/ACN. From the experimental results the absolute values of the rate parameters characterizing the primary radical ion pai...

The hydrodynamic and thermal lattice Boltzmann methods are applied to investigate the turbulent convective heat transfer in the wavy channel flows. In this study, the turbulent phenomena are modeling by large-eddy simulations with the Smagorinsky model. As a benchmark, the laminar and turbulent backward-facing step flows are simulated first. The results give good agreement with other numerical ...

It was proposed a secure group ownership transfer protocol for tags in RFID system to transfer the ownership of multiple tags simultaneously. Old owner executes authentication and updates secrets of a group of tags. Afterwards, it sends the secrets updated to new owner in a secure way. New owner also implements authentication and update procedure with tags. The protocol was analyzed by using GN...

Tag ownership transfer is an important process for RFID system. Besides the user needs to obtain the information concerning the quality of products in some scenarios, which are attached by tags. In this paper, we proposed an ownership transfer protocol with retrospective ability and analyzed its security level by using GNY logic. The results indicate that the ownership transfer protocol provide...
