... The orbits as follows are considered: INTERBALL Tail Probe (IB_TAIL) & Auroral Probe (IB_AUR), GEOTAIL (NASA/ISAS), and POLAR (NASA). ... The situation investigation aim is to select the following favourable spatial positions (FSP) : . ... FSP3 : That part of the FSP1 & FSP2 time intervals, which corresponds to the magnetic conjugations of the any couple of the considered spacecraft. ... The polar diagram plot . ... The geocentric distance (GCD) of the 4 spacecraft as a function of the time. ...

That part of the FSP1 time interval, which corresponds to the magnetic conjugations of the any couple of the 4 considered spacecraft: INTERBALL TAIL PROBE, INTERBALL AURORAL PROBE (or MAGION 5) or CLUSTER(ESA/NASA), POLAR (NASA), and GEOTAIL (NASA, ISAS). The value of the relative geocentric angular distance between magnetic field line footprints is considered during FSP3 situation selection. The mentioned angular distance value less then 5 deg is used as a criterion of the FSP3 situation. ...

... Index / Home Page / Description / Basic Idea If there is a difference between the NEPDH counter (see Table 1), giving info on the number of events which have been transmitted from the Event Analyser [EPEA] to the Data Handling Unit [EPDH]) and the number of raw events in the corresponding time interval in all active CCDs for this quadrant then the interval associated with these raw ...

... 8, ``Celestial Mechanics'', 2002 Investigation of stability of NEAs orbital resonance motions by numerical methods L. E. Bykova Tomsk State University, Tomsk, Russia The problem of orbital stability of resonance Near­Earth asteroids (NEAs) is considered. Most of NEAs have multiple close approaches to the inner ma­ jor planets. ... The technique of the investigation of NEAs orbital stability has been devel­ oped by author on the basis of the construction of possible motion domains (R) of asteroids. ...

Contractions versus extensions of holonomy maps of foliations and applications Julio Reb elo Consider a singular holomorphic foliation F on a pro jective surface. Over the leaves of F we can define real tra jectories over which the parallel transport of F yields a contraction for a natural way of measuring the distance between two leaves. ... It is then natural to consider foliations H containing a tra jectory of "infinite length" and foliations H all of whose tra jectories are of "finite length". ...

The database contains references to the papers, data files and links to the Internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to radio domain. ... References to some useful books and reviews on the subject (e.g. the classical handbooks edited by E.D.Palik) and links to Internet collections of optical constants and personal WWW pages with related software were also placed in the database. You have arrived at our welcome page. ...

Next: Results of calculations Up: Initial conditions Previous: Initial velocity . We consider motion of the stars in the Galaxy with a model axially symmetrical potential which becomes quasi-spherical at large distances from the galactic center and gives rise to the observed galactic rotation curve. As an example we have taken the galactic potential as in Paczynsky (1990) paper. The potential consists of two disk components corresponding to the galactic disc and the buldge . ...

... Values have been scaled arbitrarily. High ratios are shown in blue, corresponding to blue colors, and low ratios are shown in red, corresponding to red colors. ... Noise combined with background subtraction difficulties in the lower left quadrant of the WISP1 data (see Fig. \ref{Fig:wisp_snr_mskd}) make colors in this area very unreliable. ... The values shown here are typically a factor of ~3 less than those calculated for the Schmidt data, shown in Figure \ref{Fig:bj_alpha}. ...

Next: Mapping of FITS Up: The Data Organizer Previous: Overview of the . The Data Organizer uses as input a list of FITS files or MIDAS images as well as a list of MIDAS descriptors which are considered to be relevant (e.g., exposure time, telescope setting, instrument mode). Each of these descriptors is mapped into one column of a table that is called the Observation Summary Table (OST), and the corresponding information for a given input file is stored into one of its rows. ...

... Possible methods for receiving ultra wideband chaotic signals are considered in the case of multipath indoor propagation (line-of-sight channel model). ... Assuming that sampling time is s=1/(2f) we obtain the data rate ~ 110Mbps.So for transition of a bit we need the information interval ~ 9ns. ...

Equatorial coronal hole (top left), polar CH (top right), quiet Sun (bottom left) and quiet Sun with TCHs (bottom right) with the positions of all the corresponding identified brightening pixels over-plotted. ... We found that in comparison to the quiet Sun, the boundaries of coronal holes are abundant with brightening events including areas inside the coronal holes where closed magnetic field structures are present. ...
