This paper addresses ship detection in TerraSAR-X single-look high-resolution spotlight data by using a global thresholding approach, which is based on statistical analysis of the test data. The corresponding thresholds were determined separately from the exponential and chi-squared distributions for TerraSAR-X single-polarisation (HH or VV) and dual-polarisation (HH and VV) data. From the resu...

Polarisation vision is used by a variety of species in many important tasks, including navigation and orientation (e.g. desert ant), communication and signalling (e.g. stomatopod crustaceans), and as a possible substitute for colour vision (e.g. cephalopod molluscs). Fiddler crabs are thought to possess the anatomical structures necessary to detect polarised light, and occupy environments rich ...

We extend the analysis of Gabor transforms on a Cosmic Microwave Background (CMB) temperature map (Hansen, Górski & Hivon 2002) to polarisation. We study the temperature and polarisation power spectra on the cut sky, the so-called pseudo power spectra. The transformation kernels relating the full-sky polarisation power spectra and the polarisation pseudo power spectra are found to be similar to...

With the advancement of accelerator systems and requirements high luminosity particle beams to reach different physics goals, detectors with good position resolution rate handling capability have become essential for designing any High Energy Physics (HEP) experiments. The Gas Electron Multiplier (GEM) are widely used in many HEP experiments as a tracking device because their spatial capability...

We developed an on-line intelligent argumentation system which facilitates stakeholders in exchanging dialogues. It provides decision support by capturing stakeholders’ rationale through arguments. As part of the argumentation process, stakeholders tend to both polarise their opinions and form polarisation groups. The challenging issue of assessing argumentation polarisation had not been addres...

Polarisation measurements of pulsars and of their pulsar wind nebulae (PWNe) are uniquely able to provide deep insights into the highly magnetised relativistic environment of young, rotationpowered isolated neutron stars (INSs). Besides the radio band, optical observations are primarily suited to providing such insights. The first INS for which optical polarisation observations were performed i...

This article is the second in a series of two papers concerning mathematical study boundary integral equation kind that describes interaction N dielectric spherical particles undergoing mutual polarisation. The first presented numerical analysis Galerkin method used to solve this and derived -independent convergence rates for induced surface charges total electrostatic energy. current will focu...

Abstract This paper reports the fabrication and first demonstration of all-dielectric crystalline grating–waveguide reflectors comprising a Sc 2 O 3 waveguide grown on sub-wavelength-patterned sapphire substrate. Rigorous coupled-wave analysis is employed to simulate operation structure, suggesting 100% resonance reflectivity in theory. Structuring substrate achieved using inductively coupled p...
