Frob enius endomorphisms of linear spaces Alexander E. Guterman My research interests are in ring theory, linear algebra and combinatorics. In particular, I investigate transformations on matrices over different algebraic structures, preserving some matrix properties, sets or invariants. ... I was investigating monotone matrix transformations and developed method of matrix deformations and chain method in order to classify monotone linear and additive transformations on matrices. ...

The activities of the group started at the end of 70's with the building of FIRT: the photometer of the National Infrared Telescope ( TIRGO ). The group has also developed a large amount of software and procedures in order to define all the relevant parameters of the systems. ... See also the local Labir4Giano pages. ... In addition to the development of the above instruments, we also carried some observations in collaboration with the science groups of Arcetry Observatory. ... Giano Local Page . ...

... A set of formulae has been developed to correct aperture photometry for CTE loss with dependencies on the X and Y positions, the background counts, the brightness of the star, and the time of the observation. The observations indicate that for very faint stars on a very faint background, the CTE loss from the top to the bottom of a chip has increased from about 3% shortly after the cool-down of WFPC2 (April 23, 1994) to roughly 40% in February 1999. ... Figure 5: Same as Figure 4 for X-CTE. ...

Torgashina, Gert de Lange, Leo de Jongb, Pavel A Yagoubovb a The Kotel'nikov Institute of Radio Engineering and Electronics, Moscow, Russia b SRON Netherlands Institute for Space Research, Groningen, the Netherlands Abstract--A Superconducting Integrated Receiver (SIR) developed for balloon borne instrument TELIS covers frequency range 450-650 GHz. The DSB noise temperature was measured as low as 120 K. The SIR application for high resolution spectroscopy of breathed out air has been proven. ...

... For more distant stars we must use other techniques. ... Hence if we see a distant galaxy and can pick out any cepheids lying within it, we can calculate its distance. ... Here then is another method to gauge the size of the Universe and there are yet more. volume at high enough temperature a nuclear fusion reaction sweeps across the white dwarf's surface and eventually we will see a spectacularly bright new star (hence nova) in our skies. ... Why is this relevant to the size of the Universe? ...

... 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. ...

... In spite of the good potential possibilities, some of the station "Dnepr" design characteristics did not allow us to apply the usual special IS radar measurement methods. ... Thus for IS signal measurements at the "Dnepr" station, we have developed special methods for recording and processing IS signals in order to determine plasma ionospheric parameters. ... Equations (4-5) from the basis for data post processing to obtain ionosphere parameters. ...

... DBE is used to specify the personality to use in a digital backend that is based on an FPGA. ... RDBE_PFB is the original polyphase filter personality developed by Haystack for the RDBE digital backend ( DAR=RDBE in the station catalog). It is restricted to 16 baseband channels of 32 MHz bandwidth each, lower sideband, with frequencies of 1024-16-N*32 MHz, where N is an integer between 0 and 15. ... Those baseband channels can be as wide as 128 MHz so the full input bandwidth can be covered. ...
