High-order Cumulant-based MUSIC for Near-field Source Localization

, 2015
International audienceIn this paper, a method for near-field source localization based on MUSIC algorithm and high-order cumulant is proposed. Unlike other modified 2D MUSIC, the new method needs only one matrix to estimate the range and DOA respectively,

Symmetric cumulant $sc_{2,4} \left \{ 4 \right \}$ and asymmetric cumulant $ac_{2} \left \{ 3 \right \}$ from transverse momentum conservation and flow

Multiparticle cumulants method can be used to reveal long-range collectivity in small and large colliding systems. The four-particle symmetric cumulant $sc_{2,4} \left \{ 4 \right \}$, three-particle asymmetric cumulant $ac_{2} \left \{ 3 \right \}$, and

An Efficient Cumulative Edge-Detection Method for Image Reconstruction

CoRR
When reconstructing images from noisy measurements, such as in medical scans or scientific imaging, we face an inverse problem: recovering an unknown image from indirect, corrupted observations. These problems are typically ill-posed, meaning small amounts of noise can lead to inaccurate reconstructions.

Systematic nonperturbative approach for thermal averages in quantum many-body systems: the thermal-cluster-cumulant method

, 1993
We present in this paper a systematic nonperturbative cluster-cumulant method for deriving thermal averages of operators in quantum many-body systems.

Symmetry-based efficient simulation of higher-order coherences in quantum many-body superradiance

Physical Review Research
We propose an efficient method to numerically simulate the superradiant emission dynamics of large numbers of quantum emitters in ordered arrays in the presence of long-range dipole-dipole interactions mediated by the vacuum electromagnetic field.

A Switched IMM Estimator Based on the Model Probability Cumulant [PDF]

, 2013
Taking into account the disadvantage of the potential loss of accuracy due to the overmodeling at these nonmaneuvering times in the interacting multiple model (IMM) method, an improved IMM algorithm based on the Viterbi technique and the model ...

Simulated Annealing Wavelet Estimation Via Fourth-Order Cumulant Matching

, 1996
The fourth-order cumulant matching method has been developed recently for estimating amixed-phase wavelet from a convolutional process. Matching between the trace cumulant and the wavelet moment is done in a minimum mean-squared error sense under the
