Abstract
In the present work, the separation of He/CH4 through different polymeric membranes has been considered. In this regard, composite flat sheet membranes are prepared from different amounts of poly(vinyl acetate) (PVAc) (0–40
wt%). Gas permeability were studied for the prepared membranes. The results demonstrated that the ABS/PVAc (00
wt%) membrane revealed higher permeability. Afterwards, novel mixed matrix membranes were prepared by incorporating 1–5 wt% SiO0 nanoparticles into the ABS/PVAc (00 wt%). The primary results of the prepared mixed matrix membranes showed a significant increase in the He permeability by incorporating the SiO0 nanoparticles into the blend membranes. Finally, we predicted performance of membrane with Maxwell model and calculated AARE% .

Abstract

Mobile applications are increasingly exploiting cloud computing to overcome the resource limitations of mobile devices. To this end, the most computationally expensive tasks are offloaded to the cloud and the mobile application simply interacts with a remote service through a network connection. One way to establish such a connection is given by remote display access, in which a mobile device just operates as a thin client by relaying the input events to a server and updating the screen based on the content received. In this article, we specifically address remote display access as a means for mobile cloud computing, with focus on its power consumption at mobile devices. Different from most of the existing literature, we take an experimental approach based on real user sessions employing different remote access protocols and types of applications, including gaming. Through several experiments, we characterize the impact of the different protocols and their features on power consumption and network utilization. We conclude our analysis with considerations on usability and user experience.
