The Influence of Random Element Displacement on DOA Estimates Obtained with (Khatri–Rao-)Root-MUSIC [PDF]
Sensors, 2014 Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...

Calibrating Dependence Between Random Elements [PDF]
Journal of Theoretical Probability, 2020 Attempts to quantify dependence between random elements X and Y via maximal correlation go back to Gebelein (1941) and R nyi (1959). After summarizing properties (including some new) of the R nyi measure of dependence, a calibrated scale of dependence is introduced. It is based on the ``complexity`` of approximating functions of X by functions of Y.

Data Streams as Random Permutations: the Distinct Element Problem [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 In this paper, we show that data streams can sometimes usefully be studied as random permutations. This simple observation allows a wealth of classical and recent results from combinatorics to be recycled, with minimal effort, as estimators for various ...

Dim and Small Target Detection Based on Gaussian Markov Random Field Motion Direction Estimation
IEEE Access, 2022 To improve the detection of dim and small targets in low signal-to-noise ratio (SNR < 3dB) scenarios, energy accumulation along the estimated direction by estimating the direction of the target’s motion at different moments is a proven ...

Research on random propagation method of hydraulic fracture based on zero-thickness cohesive element
Rock and Soil Mechanics, 2021 In order to effectively simulate the process of random propagation of hydraulic fractures in fractured shale reservoirs, a new method of random propagation of hydraulic fractures based on the finite element mesh embedded with zero-thickness cohesive ...
