... Actor Prolog supports so-called repeated proving of sub-goals. ... Logical actors are a name of these repeatedly proved sub-goals. ... A logic program consists of sub-goals that must be proven in the course of an execution of the program (like a usual imperative program consists of commands to be executed). ... There are some logical actors in the outside world from the standpoint of the ideology of Actor Prolog , and a program interacts with these external actors. ...

SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ...

RTT150 . ... The primary mirror 1 reflects light to the secondary mirror 2 which sends the converging beam of light to the system of four flat mirrors 3, 4, 5 and 6. That allows the beam of light to leave the telescope strictly along its polar axis and be collected in Coude focus. ... That's why at any tube position (for any rotation along the declination axis) beam of light parallel to the principal axis after reflection on mirror 3 follows the direction of declination axis. ...

... 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...

Comment on J2246-1206 . In contrast to the jet pointing to the NE in our image, the 5 GHz VLBI image of Shen et al. (1998) shows no indication of extended emission above the 20 mJy/beam level. Hong et al. (1999) find a jet component to the SE and identify that with a "superluminal" component possibly ejected in 1992. A 15 GHz image from the USNO database, taken nearly at the same epoch as the image of Hong et al. (1999) does not show any component at this position angle. ...
