Multispheroidal model of magnetic field of uncertain extended energy-saturated technical object
Electrical engineering & ElectromechanicsProblem. The implementation of strict requirements for magnetic silence of elongated energy-saturated technical objects – such as naval vessel and submarines is largely determined by the adequacy of mathematical models to the signatures of a real ...

A Two-Colour CCD Survey of the North Celestial Cap: I. The Method [PDF]
, 2009 We describe technical aspects of an astrometric and photometric survey of the North Celestial Cap (NCC), from the Pole (DEC=90 deg) to DEC=80 deg, in support of the TAUVEX mission.

Characterizing AGB stars in Wide-field Infrared Survey Explorer (WISE) bands [PDF]
, 2014 Since asymptotic giant branch (AGB) stars are bright and extended infrared objects, most Galactic AGB stars saturate the Wide-field Infrared Survey Explorer (WISE) detectors and therefore the WISE magnitudes that are restored by applying point-spread ...

The Discovery of Cometary Activity in Near-Earth Asteroid (3552) Don Quixote [PDF]
, 2013 The near-Earth object (NEO) population, which mainly consists of fragments from collisions between asteroids in the main asteroid belt, is thought to include contributions from short-period comets as well.

The XMM-LSS survey: The XMDS/VVDS 4 sigma catalogue [PDF]
, 2005 We present a first catalogue of X-ray sources resulting from the central area of the XMM-LSS (Large Scale Structure survey). We describe the reduction procedures and the database tools we developed and used to derive a well defined catalogue of X-ray ...

Crossover of skyrmion and helical modulations in noncentrosymmetric ferromagnets [PDF]
, 2018 The coupling between angular (twisting) and longitudinal modulations arising near the ordering temperature of noncentrosymmetric ferromagnets strongly influences the structure of skyrmion states and their evolution in an applied magnetic field.

An XMM-Newton observation of the young open cluster NGC 2547: coronal activity at 30 Myr
, 2005 We report XMM-Newton observations of the young open cluster NGC 2547 which allow us to characterise coronal activity in solar-type stars at an age of 30 Myr. X-ray emission peaks among G-stars at luminosities (0.3-3keV) of Lx~10^{30.5} erg/s and declines

On the use of Neumann's principle for the calculation of the polarizability tensor of nanostructures
, 2007 The polarizability measures how the system responds to an applied electrical field. Computationally, there are many different ways to evaluate this tensorial quantity, some of which rely on the explicit use of the external perturbation and require ...
