In this study, two-dimensional pulsating unsteady flow of nanofluid through a rectangular channel with isothermal walls is investigated numerically. The set of resultant algebraic equations is solved simultaneously using SIMPLE algorithm to obtain the velocity and pressure distribution within the channel. The effects of several parameters, such as volume fraction of different nanoparticles, Rey...

Scattering of light by cloud, haze, and fog decreases the transmission efficiency communication channels in quantum key distribution (QKD), reduces system's practical security, thus constrains deployment free-space QKD. Here, we employ wavefront shaping technology to compensate distorted optical signals high-loss scattering fulfill a polarization-encoded BB84 QKD experiment. With this channel c...

This paper investigates equilibrium strategies for both horizontal (HJP) and vertical (VJP) joint promotions (cooperative advertising) in the supply chain. A game theoretic model is solved for two setups: a centralized channel competing with a decentralized one (DC), and two competing decentralized channels (DD). Retailers decide of HJP and regular promotional efforts, as well as of prices. Man...
