Measures of network structural integrity useful in the analysis and synthesis of power systems are discussed. Signal flow methodology is applied to derive an expression for the paths between sources and sinks in a power network. Connectivity and reach ability properties of the network are obtained using the minors of a modified connectivity matrix. Node-connectivity, branch connectivity and mix...

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 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...

Understanding the mechanisms of regional steric sea level variability is fundamental to understand recorded by satellite altimetry for years and insure that future projections made climate models are realistic. Here, we first develop a novel method based on variance budget allows detect sources sinks variability. Using “Estimating Circulation Climate Ocean” (ECCO V4) state estimate, then show i...
