Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids [PDF]
, 2015 Sound sources at the same angle in front or behind a two-microphone array (e.g., bilateral hearing aids) produce the same time delay and two estimates for the direction of arrival: A front-back confusion.

Reversible Data Hiding with a New Local Contrast Enhancement Approach
Mathematics, 2022 Reversible data hiding schemes hide information into a digital image and simultaneously increase its contrast. The improvements of the different approaches aim to increase the capacity, contrast, and quality of the image.

Multi-sensor fire detection by fusing visual and non-visual flame features [PDF]
, 2010 This paper proposes a feature-based multi-sensor fire detector operating on ordinary video and long wave infrared (LWIR) thermal images. The detector automatically extracts hot objects from the thermal images by dynamic background subtraction and ...

Phase-shift extraction for phase-shifting interferometry by histogram of phase difference
Optics Express, 2010 We propose a non-iterative approach to extract the unknown phase shift in phase shifting interferometry without the assumption of equal distribution of measured phase in [0,2π]. According to the histogram of the phase difference between two adjacent frames, the phase shift can be accurately extracted by finding the bin of histogram with the highest ...

Confronting Synchrotron Shock and Inverse Comptonization Models with GRB Spectral Evolution [PDF]
, 1997 The time-resolved spectra of gamma-ray bursts (GRBs) remain in conflict with many proposed models for these events. After proving that most of the bursts in our sample show evidence for spectral "shape-shifting", we discuss what restrictions that BATSE ...

Correlation methods for the analysis of X-ray polarimetric signals [PDF]
, 2018 X-ray polarimetric measurements are based on studying the distribution of the directions of scattered photons or photoelectrons and on the search of a sinusoidal modulation with a period of {\pi}.

Design and Test of a Forward Neutron Calorimeter for the ZEUS Experiment [PDF]
, 1997 A lead scintillator sandwich sampling calorimeter has been installed in the HERA tunnel 105.6 m from the central ZEUS detector in the proton beam direction. It is designed to measure the energy and scattering angle of neutrons produced in charge exchange
