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". ...

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. ...

Next: Simulated Results with Up: Assessment of Methods Used Previous: Introduction . ... Then one has to use regularized inversion methods in order to obtain approximate and sensible solutions. ... All these methods contain a free parameter which is the so-called regularization parameter; in the case of method ( ) this is a smoothing of the higher spatial frequencies; for the methods ( ) - ( ), it is the number of iterations. ... In the case of method ( ) the iteration scheme is given by . ...

Text of report The subject if our report is the influence of the structure and physics of the uppermost superadaibatic layers on the oscillational spectrum of p-modes. ... In our report we will try to use a most simple representation of the spectrum, plotting the differences between theoretical (that is models') and observational frequencies against a frequency. ... It allow us to focused on the effects of the uppermost layers and ignore possible sophistications from effect of more deeper layers. ...

VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...
