What is the VSM ? ... VRML = Virtual Reality Modeling Language. ... One of the best VRML viewers, if not the best, is Netscape Navigator with Live3D plugin. ... Warning: if you use any other viewer, spacecraft will probably look like parrots or clowns because each VRML viewer treats colors in its own unpredictable way. ... You can use these VRML models freely in any way you like, but: 1) let me know you use them; 2) if you add them to your Web page, a reference to the VSM must be there. ...

... Field of interest: data analysis and interpretation of X-ray observations of BHC and NS systems, astrophysics of compact objects and related phenomena: X-ray , optical and radio observations , shocks and stellar winds, emission mechanism, the spectral and timing analysis of the X-ray emission from microquasars ( signature of accreting BH), atoll- and Z-sources ( signature of accreting NS), modeling of INTEGRAL images % . ...

A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...

... Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear enable us to see the flaring structure of the disks around Herbig Ae stars. Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. ...

... COMPUTER SIMULATION OF RADIOWAVE MULTIPLE SCATTERING EFFECTS IN IONOSPHERE USING MONTE-CARLO METHOD . ... Distribution of reflected radiation on the ground is computed. ... Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ... Radiation energy transfer in the slab is modeled by distribution of some particles carring small portions of radiation energy. ... The isotropic plasma approximation is...
