Fluctuations in concentration of organic vapors in gas streams that are treated by devices such as biofilters or oxidizers make it challenging to remove the vapors from the gas streams in an efficient and economic manner. Combining adsorption with concentration-controlled desorption provides an active buffer between the source of vapors and the control device for better control of concentration...

Carbon capture refers to the removal of carbon dioxide from atmosphere, or directly at source its emissions. The latter employs chemical engineering design systems for industries. Aqueous amine scrubbing makes use based solvents flue gas streams. carbon, once captured, is compressed and redirected either reutilisation storage. In enhanced oil recovery, CO2 injected into reservoirs increase thei...

biofiltration method is one of the most commonly used and most effective methods to removepollutants from the exhaust gas flow from different industries. one of the most important categories of airpollutants is hap (hazardous air pollutants). this study assesses the ability of biofiltration method toremove and treat hap dea (diethanolamine) from a gas stream through a laboratory-scale biofilter...

This article describes an experimental laboratory system that generates and distributes random binary sequence bit streams between two optical terminals (labeled Alice and Bob). The random binary sequence is generated through probing the optical channel of a turbulent atmosphere between the two terminals with coincident laser beams. The two laser beams experience differential phase delays while...

REGULAR PROGRAMMING OVER DATA STREAMS

I develop an asset-pricing model in which financial assets are valued for their liquidity– the extent to which they are useful in facilitating exchange–as well as for being claims to streams of consumption goods. The implications for average asset returns, the equitypremium puzzle, and the risk-free rate puzzle, are explored both analytically and quantitatively in a version of the model that ne...

Computer T he widespread adoption of streaming video on the Internet appears ready to become the next major frontier for online multimedia. Graphics, animation, and audio technologies have already proliferated on the Internet. However, streaming video—in which viewers can begin watching content almost as soon as it starts downloading—is only now developing as a mainstream technology. “In the pa...
