We analyze the variability in the x-ray lightcurves of the black hole candidate Cygnus X-1 by linear and nonlinear time series analysis methods. While a linear model describes the overall second order properties of the observed data well, surrogate data analysis reveals a significant deviation from linearity. We discuss the relation between shot noise models usually applied to analyze these dat...

We study charge transport through a topological superconductor with a pair of Majorana end states coupled to leads via quantum dots with resonant levels. The nonlocality of the Majorana bound states opens the possibility of crossed Andreev reflection with nonlocal shot noise due to the injection of an electron into one end of the superconductor followed by the emission of a hole at the other en...

Nonequilibrium situations where selected currents are suppressed of interest in fields like thermoelectrics and spintronics, raising the question how related noises behave. We study such zero-current charge, spin, heat a two-terminal mesoscopic conductor. In presence voltage, temperature biases, nonequilibrium (shot) can be arbitrarily large, even if their average vanish. However, as soon bias ...

Shot peening applies a residual compressive stress field (RCSF) on the surface of parts. It also shifts “crack nucleation sites” to sub-surface locations. A nondestructive method of measuring the stresses, Sin2ψ was utilized here and the stress values introduced to Ansys software. For this purpose, uniform stress in all directions was applied on the con rod. Loading on the rod in Ansys had thre...

Prediction of future values of a shot noise process observed on a discrete lattice of points is considered. The shot magnitudes are assumed to be independent and identically distributed and arrive via a Poisson process; the eeect of each shot dissipates and/or accumulates according to a known shot function. Conditional mean and linear point predictors of future process values are developed. Dis...

A common video indexing technique is to segment a video sequence into shots and then select representative key-frames. The process of shot break detection is a fundamental component in automatic video indexing, editing, and archiving. This paper introduces a novel video cut detection technique which performs in the frequency domain. It is computationally tractable and robust with respect to sud...
