Signal separation using second- and high-order statistics [PDF]
Summary: This paper presents two methods for signal separation. In either method, the fundamental criterion for separation relies on reducing to zero, or at least minimizing, the output cross-correlation or cross-cumulant functions of a decoupling multi-input-multi-output system that is fed with mixed signals.

Advanced intermittent clutter filtering for radar wind profiler: signal separation through a Gabor frame expansion and its statistics [PDF]
A new signal processing method is presented for the suppression of intermittent clutter echoes in radar wind profilers. This clutter type is a significant problem during the seasonal bird migration and often results in large discrepancies between ...

Sequential approach to blind source separation using second order statistics [PDF]
A general result on identifiability for the blind source separation problem, based on second order statistics only, is presented in this paper. The separation principle using second order statistics only is first proposed.

Dynamical localization of chaotic eigenstates in the mixed-type systems: spectral statistics in a billiard system after separation of regular and chaotic eigenstates [PDF]
We study the quantum mechanics of a billiard (Robnik 1983 J. Phys. A: Math. Gen. 16 3971) in the regime of mixed-type classical phase space (the shape parameter λ = 0.15) at very high-lying eigenstates, starting at about 1.000.000th eigenstate and ...

Statistics of Simulated and Observed Pair Separations in the Gulf of Mexico [PDF]
AbstractPair-separation statistics of in situ and synthetic surface drifters deployed near the Deepwater Horizon site in the Gulf of Mexico are investigated. The synthetic trajectories derive from a 1-km-resolution data-assimilative Navy Coastal Ocean Model (NCOM) simulation. The in situ drifters were launched in the Grand Lagrangian Deployment (GLAD).

Second order statistics based blind source separation for artifact correction of short ERP epochs [PDF]
ERP is commonly obtained by averaging over segmented EEC epochs. In case artifacts are present in the raw EEC measurement, pre-processing is required to prevent the averaged ERP waveform being interfered by artifacts. The simplest pre-processing approach

Efficient Aggregated Kernel Tests using Incomplete U-statistics [PDF]
We propose a series of computationally efficient nonparametric tests for the two-sample, independence, and goodness-of-fit problems, using the Maximum Mean Discrepancy (MMD), Hilbert Schmidt Independence Criterion (HSIC), and Kernel Stein Discrepancy ...

Mechanical theory of nonequilibrium coexistence and motility-induced phase separation [PDF]
Significance Phase separation, the coexistence between distinct macroscopic phases (such as oil coexisting with water), is ubiquitous in everyday life and motivated the development of the equilibrium theory of coexistence by Maxwell, van der Waals, and ...
