Identification of individual coherent sets associated with flow trajectories using coherent structure coloring.

We present a method for identifying the coherent structures associated with individual Lagrangian flow trajectories even where only sparse particle trajectory data are available. The method, based on techniques in spectral graph theory, uses the Coherent Structure Coloring vector and associated eigenvectors to analyze the distance in higher-dimensional eigenspace between a selected reference tr...

Estimating dissipation from single stationary trajectories.

In this Letter we show that the time reversal asymmetry of a stationary time series provides information about the entropy production of the physical mechanism generating the series, even if one ignores any detail of that mechanism. We develop estimators for the entropy production which can detect nonequilibrium processes even when there are no measurable flows in the time series.

Retrieve Ground Parameters from Quasi-coherent Targets for Sar Interferometry

This paper presents a multi-baseline DInSAR algorithm to obtain ground deformation and topography parameters from Quasi Coherent Targets (Q-CTs), such as the bare land and light cultivated areas that distribute broadly on the suburban ground surface. In this study the physical classification characteristics and coherence features are analyzed for Q-CTs targets selection. And a linked parameters...

Modified Structure Function Model Based on Coherent Structures

In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results...

He Structure from Coherent Hard Exclusive Processes

Hard exclusive processes, such as deep electroproduction of photons and mesons off nuclear targets, could give access, in the coherent channel, to nuclear generalized parton distributions (GPDs). Here, a realistic microscopic calculation of the unpolarized quark GPD H3 q of the 3He nucleus is reviewed. In Impulse Approximation, H3 q is obtained as a convolution between the GPD of the internal n...
