Theoretical and experimental characterizations of gigahertz acoustic streaming in microscale fluids

Even as gigahertz(GHz) acoustic streaming has developed into a multi-functional platform technology for biochemical applications, including ultrafast microfluidic mixing, microparticle operations, and cellar or vesicle surgery, its theoretical principles have yet to be established. This is because few studies have been conducted on the use of such high frequency acoustics in microscale fluids. Another difficulty is t...  (本文共9页) 阅读全文>>

Preliminary analysis of back-streaming electrons on the source plasma region of ion sources for the EAST-NBI

Back-streaming electrons gain significant energy due to the high voltage of the extraction system for a high-current ion source.By theoretical calculation,the particle flux accounts for 13.88%of the total beam current,and the power flux accounts for about 7.5%of the total beam power.This shows that back-streaming electrons are very destructive to the plate of electron absorption that is installed opposite of the ac...  (本文共5页) 阅读全文>>

A study on TCP performance of crowdsourced live streaming

The prevalence of smart phone and improvement of wireless net promote the usage of crowdsourced live streaming,where individual users act as live streaming sources to broadcast themselves online. Characterizing the performance and identifying its bottleneck in such systems can shed light on the system design and performance optimization. TCP performance of a commercial crowdsourced live streaming system ...  (本文共8页) 阅读全文>>
