Sparse Regression Algorithm for Activity Estimation in γ Spectrometry
We consider the counting rate estimation of an unknown radioactive source, which emits photons at times modeled by an homogeneous Poisson process. A spectrometer converts the energy of incoming photons into electrical pulses, whose number provides a rough estimate of the intensity of the Poisson process. When the activity of the source is high, a physical phenomenon known as pileup effect disto...
متن کاملMeasuring γ–ray dose of terrestrial samples using β-γ Spectrometry
Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
متن کاملSpectral techniques applied to sparse random graphs
We analyze the eigenvalue gap for the adjacency matrices of sparse random graphs. Let λ1 ≥ . . . ≥ λn be the eigenvalues of an n-vertex graph, and let λ = max[λ2, |λn|]. Let c be a large enough constant. For graphs of average degree d = c log n it is well known that λ1 ≥ d, and we show that λ = O( √ d). For d = c it is no longer true that λ = O( √ d), but we show that by removing a small number...
متن کاملRestoration of Simulated EnMAP Data through Sparse Spectral Unmixing
This paper proposes the use of spectral unmixing and sparse reconstruction methods to restore a simulated dataset for the Environmental Mapping and Analysis Program (EnMAP), the forthcoming German spaceborne hyperspectral mission. The described method independently decomposes each image element into a set of representative spectra, which come directly from the image and have previously undergon...
