Estimation of Two-Dimensional Non-Symmetric Incoherently Distributed Source with L-Shape Arrays
Sensors, 2019 In the field of array signal processing, distributed sources can be regarded as an assembly of point sources within a spatial distribution. In this study, a two-dimensional (2D) non-symmetric incoherently distributed (ID) source model is proposed; we ...

Intra-Class Mixup for Out-of-Distribution Detection
IEEE Access, 2023 Deep neural networks (DNNs) have found widespread adoption in solving image recognition and natural language processing tasks. However, they make confident mispredictions when presented with data that does not belong to the training distribution, i.e ...

Observed luminosity spread in young clusters and Fu Ori stars: a unified picture [PDF]
, 2012 The idea that non steady accretion during the embedded phase of protostar evolution can produce the observed luminosity spread in the Herzsprung-Russell diagram (HRD) of young clusters has recently been called into question.

Laser Cooling of TeV Muons [PDF]
, 2000 We show that Compton scattering can be used to cool TeV-scale muon beams, and we derive analytical expressions for the equilibrium transverse angular spread, longitudinal energy spread, and power requirements.

A Method to Determine the In-Air Spatial Spread of Clinical Electron Beams [PDF]
, 1999 We propose and analyze in detail a method to measure the in-air spatial spread parameter of clinical electron beams. Measurements are performed at the center of the beam and below the adjustable collimators sited in asymmetrical configuration in order to

Decoupled Estimation of 2D DOA for Coherently Distributed Sources Using 3D Matrix Pencil Method
EURASIP Journal on Advances in Signal Processing, 2008 A new 2D DOA estimation method for coherently distributed (CD) source is proposed. CD sources model is constructed by using Taylor approximation to the generalized steering vector (GSV), whereas the angular and angular spread are separated from signal ...

A Technique for Photometric Detection and Measurement of Unresolved Binary Systems [PDF]
, 1997 A technique is described for the detection and measurement of close binary systems whose images are unresolved. The method is based on analysis of the moment of inertia tensor of the image, from which the product of the binary flux ratio and square of ...

Analysis and evaluation of secondary photons originated in jaws as contamination particles at the phantom surface [PDF]
Ядерна фізика та енергетика, 2020 The present work is focused on the study of the geometry and material of a beam modifier (jaws), which is crucial for Linac improvement by reducing secondary photons emergent from it.
