... We describe image compression based on the pyramidal median transform, introduced as an alternative to the use of a wavelet transform. The use of a multiresolution support allows ``protection'' of astronomical objects in the image. ... We describe an approach to astronomical image compression through noise removal. ... We begin by explaining why transforms other than the wavelet transform are important for astronomical image compression. ... Negative Values. ... The image dimensions were . ...

... 8, ``Celestial Mechanics'', 2002 Determination of preliminary orbits including perturbations V. A. Shefer Research Institute of Applied Mathematics and Mechanics, Tomsk State University, Tomsk, Russia On the basis of the theory of intermediate orbits developed earlier by the au­ thor [1], a new approach to the solution of the problem of preliminary orbit determination is suggested. This approach enables to take into account the main perturbations in celestial body motion. ...

LIGHT SCATTERING BY MULTI-LAYERED PARTICLES WITH THE AXIAL SYMMETRY V.G. Farafonov St.Petersburg State University of aerocosmic instrumentation, St.Petersburg, Russia Abstract A new recursive algorithm of solution of the problem of scattering of an arbitrary polarized plane wave by multi-layered dielectric particles with the axial symmetry is constructed. ... The size of truncated? systems for multi-layered particles coincides with that of analogical homogeneous particles. ...

Recent years have seen a downgrading of the threat assessment due to impacts from comets and asteroids. ... Bill Napier, however, has been using new approaches to the problem and finds that the celestial hazard due to impacts may be a factor 5 higher these estimates. ... These bodies may constitute the dominant impact hazard in the 100,000 megaton range. ...

SKA ­ TDT Group On Phase Computation during Folding C.Baffa, E.Giani January 2014 The last part of pulsar search algorithm, as in the SKA TDT group approach, is the verification and optimization of pulsar parameters candidates identified in the previous phases. ... As the phase errors are expressed as fractions of the full period (in our case 44 measurement of 50 s), it is evident that the maximum integration time compatible with single precision phase computation is very short. ...

Эта эмблема была разработана для экипажей корабля OV 101 Enterprise, на котором в 1977 году проводились испытательные полеты (Approach and Landing Test) в атмосфере при сбрасывании с самолета Boeing-747 на высоте в 25000 футов (7 620 м). Эмблема представляет собой круг, сочетающий в себе синий, белый и красный цвета - основные цвета американского флага. На красном треугольнике, обращенном острой вершиной вверх, символизируя стремление в космос, помещено изображение шаттла Enterprise. ...

... arXiv.org . ... Modeling Light Curves for Improved Classification . ... These include heterogeneity of the data, irregularly sampled data, missing data, censored data, known but variable measurement errors, and most importantly, the need to classify in astronomical objects in real time using these imperfect light curves. We describe a modeling-based approach using Gaussian process regression for generating critical measures representing features for the classification of such lightcurves. ...

How Do Children Learn? ... Here we propose an innovative approach to children's learning, one that integrates the transmission, constructivism, and social constructivism models by having teachers present some of the fundamental concepts involved in astronomy education at the elementary level. ... learn the story . ...
