... 8, ``Celestial Mechanics'', 2002 Orbits with osculation of higher orders and their use in celestial mechanics Yu. V. Batrakov Institute of Applied Astronomy, St. Petersburg, Russia The idea of the generalized or intermediate orbits with osculation of the second and third order was proposed and considered rigorously in 1981 [1]. ... The equations of the perturbed motion in the elements of the generalized (intermediate) orbits were derived for the first time in [5,6]. ... Batrakov Yu. ...

FINE STRUCTURE OF CHAOTIC ATTRACTOR FOR MULTIPLE-ACCESS COMMUNICATIONS Alexander S. Dmitriev and Sergey O. Starkov Institute of Radio Engineering and Electronics, Russian Academy of Sciences Mochovaya st.,11, GSP-3, Moscow 103907, Russia E-mail: chaos@mail.cplire.ru ABSTRACT A method for multiple access using the structure of the unstable periodic orbits of chaotic attractor is proposed. ... The first phase is a system transition from chaotic motion to the required unstable periodic orbit. ...

Received 2011 Sep 15; in original form 2011 Feb 6 ABSTRACT The bimodal galaxy distribution in the optical colourmagnitude diagram (CMD) comprises a narrow "red sequence" populated mostly by early-type galaxies and a broad "blue cloud" dominated by star-forming systems. ...
... Three energetic mechanisms are considered: multiple supernova explosions (SNe), a hypernova explosion associated with a gamma ray burst (GRB), and the vertical impact of a high velocity cloud (HVC). ... As a consequence, multiple SNe form rings with a high ring-to-center contrast K < 100 in the HI column density, whereas single hypernova explosions form rings with K < 10. ... Our simulations show (see Fig. 6) that both multiple SNe and single hypernovae may form rings of up to 2 kpc in diameter. ...
