An intensive aerosol and gases campaign was performed at Shanghai in the Yangtze River Delta region over Eastern China from late March to early June 2009. This study provided a complementary picture of typical haze types and the formation mechanisms in megacities over China by using a synergy of ground-based monitoring, satellite and lidar observations.(More)
We employ a recently proposed model [Murisic et. al, JFM 2013] to study a finite-volume, particle-laden thin film flowing under gravity on an incline. For negatively buoyant particles with concentration above a critical value, the similarity solution is of the rarefaction-singular shock type. We investigate the structure in detail and find that the(More)
—Many of the design companies cannot afford owning and acquiring expensive foundries and hence, go fabless and outsource their design fabrication to foundries that are potentially untrustwrothy. This globalization of Integrated Circuit (IC) design flow has introduced security vulnerabilities. If a design is fabricated in a foundry that is outside the direct(More)
—A compact dual-band power divider for GSM/DCS applications is proposed in this letter. Novel planar artificial transmission lines are applied to miniaturize the power divider and achieve wideband response. The proposed dual-band power divider is about 37% of conventional one. The design principle, simulated and measured results are all discussed. The(More)
—Microwave imaging of buried objects has been widely used in sensing and remote-sensing applications. It can be formulated and solved as inverse scattering problems. In this paper, we propose a hybrid numerical technique based on the parallel genetic algorithm (GA) and the finite-difference time-domain (FDTD) method for determining the location and(More)
A relatively simple method of characteristics is developed to simulate one-dimensional variably saturated water flow. The method uses the Eulerian-Lagrangian approach to separate the governing flow equation into " convection " and " diffusion " parts, which are solved with the method of characteristics and the conventional finite element method,(More)
