CO2 capture and storage (CCS) is widely regarded as a key technology for reducing greenhouse gas emissions from large industrial point sources. It entails the capture of a relatively pure CO2 from exhaust gases using different techniques, and then storing this captured gas in various geological sinks. Large-scale deployment of CCS requires the comprehensive evaluation of candidate sources and s...

We are interested in how to best communicate a (usually real valued) source to a number of destinations (sinks) over a network with capacity constraints in a collective fidelity metric over all the sinks, a problem which we call joint networksource coding. Unlike the lossless network coding problem, lossy reconstruction of the source at the sinks is permitted. We make a first attempt to charact...

Mobile sinks are proposed to save sensor energy spent for multihop communication in transferring data to a base station (sink) in Wireless Sensor Networks. Due to relative low speed of mobile sinks, these approaches are mostly suitable for delay-tolerant applications. In this paper, we study the design of a query scheduling algorithm for query-based data gathering applications using mobile sink...

We present the results of an experimental study of sink and source defects in a one-dimensional pattern of traveling fingers that form at a driven fluid-air interface. We find that sinks and sources behave differently: Sinks separate regions of differing wave number and move smoothly so as to keep the phase difference across the sink fixed. They are transient objects which are eventually destro...
