MEASUREMENTS OF ARRIVAL TIME DISTRIBUTIONS OF EAS MUONS WITH THE FACILITIES OF THE KASCADE CENTRAL DETECTOR

open access: yes, 2007
The central detector of the KASCADE experiment is equipped with a trigger and timing facility, which enables measurements of the arrival time distributions of muons hitting the central detector.

Angle of arrival estimation using BLE technology and antenna array

open access: yes, 2022
Zasnovali smo sistem za oceno kota prihoda signala s tehnologijo nizkoenergij- skega Bluetootha, ki je z namenom bolj natančnega določanja lokacij naprav, v standard verzije 5.1 dodal funkcionalnost za oceno kota prihoda signala (ang.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

3D Angle-of-Arrival Positioning Using von Mises-Fisher Distribution

open access: yes, 2018
We propose modeling an angle-of-arrival (AOA) positioning measurement as a 3-dimensional von Mises-Fisher (VMF)-distributed unit vector instead of the conventional normally distributed azimuth and elevation measurements.

Angle of Arrival Estimator Utilizing the Minimum Number of Omnidirectional Microphones

open access: yesJournal of Marine Science and Engineering
In sound signal processing, angle of arrival indicates the direction from which a propagating sound signal arrives at a point where multiple omnidirectional microphones are positioned.

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Curl antenna lens as angle of arrival sensor

open access: yes, 2009
A lens antenna consisting of a double-sided 3 x 3 array of curl antennas that can convert an incident LH/RHCP signal into a transmitted LH/RHCP signal is shown to have an additional property that allows the angle of incidence of an incoming linear or ...
