It is demonstrated that due to back-reaction of quantum effects, expansion of the universe stops at its maximum and takes a turn around. Later on, it contracts to a very small size in finite future time. This phenomenon is followed by a " bounce " with rebirth of an exponentially expanding non-singular universe. It is explored that this exponential expansion may stop at some time after bounce, ...

Microscopic imaging ellipsometry is an optical technique that uses an objective and sensing procedure to measure the ellipsometric parameters ? and ? in the form of microscopic maps. This technique is well known for being noninvasive and label-free. Therefore, it can be used to detect and characterize biological species without any impact. Microscopic imaging ellipsometry was used to measure th...

conclusions the educational framework provided by im for at training improved attitude and behavioral beliefs that can facilitate the adoption of at behavior and decreased clbp. results significant differences were recorded before and after intervention (p < 0.001) for the model constructs of intention, perceived risk, direct attitude, behavioral beliefs, and knowledge in both groups. direct at...

We quantitatively evaluate the capability and accuracy of the lattice Boltzmann equation (LBE) for modeling flow through porous media. In particular, we conduct a comparative study of the LBE models with the multiple-relaxation-time (MRT) and the Bhatnagar– Gross–Krook (BGK) single-relaxation-time (SRT) collision operators. We also investigate several fluid–solid boundary conditions including: ...

In design of complex arithmetic logic circuits, ground bounce noise, standby leakage current and leakage power are important and challenging issues in nanometer down scaling. In this paper, a low power, low complex and reduced ground bounce noise full adder design based on pass transistor logic (PTL) is proposed. Basically adder is vital part of complex arithmetic logic circuit in arithmetic op...

BACKGROUND While resilience has been defined as resistance to illness, adaptation, and thriving, the ability to bounce back or recover from stress is closest to its original meaning. Previous resilience measures assess resources that may promote resilience rather than recovery, resistance, adaptation, or thriving. PURPOSE To test a new brief resilience scale. METHOD The brief resilience sca...

Design complexity is increasing day by day in modern digital systems. Due to reconfigurable architecture, low non recurring engineering (NRE) and ease of design field programmable gate arrays (FPGA) become a better solution for managing increasing design complexity. Due to scaling trends FPGA uses more transistors which increase the leakage current. FPGAs are well suited for wireless applicatio...

In this paper we analytically solve the velocity of the lattice Boltzmann BGK equation [LBGK) Ibr several simple flows. The analysis provides a framework to theoretically analyze various boundary conditions. In particular, the analysis is used to derive the slip velocities generated by various schemes for the nonslip boundary condition. We find that the slip velocity is zero as long as Z=J~e~ =...

This work examines the slip boundary condition by Lattice Boltzmann simulations, addresses the validity of the Navier’s hypothesis that the slip velocity is proportional to the shear rate and compares the Lattice Boltzmann simulations to the experimental results of Tretheway and Meinhart (Phys. of Fluids, 14, L9-L12). The numerical simulation models the boundary condition as the probability, P,...
