The fuzzy model of ships collision risk rating in a heavy traffic zone
The fuzzy model to determine the risk collision rating of ships in a heavy traffic zone is proposed. Fuzzy system includes four inputs and one output linguistic variables, describing collision risk rating. The fuzzy sets corresponding to the term of these linguistic variables and their graphical view is represented. The product base contains 400 fuzzy rules, making by a maneuverable plane-table
The Non-Relativistic Evolution of GRBs 980703 and 970508: Beaming-Independent Calorimetry
We use the Sedov-Taylor self-similar solution to model the radio emission
from the gamma-ray bursts (GRBs) 980703 and 970508, when the blastwave has
decelerated to non-relativistic velocities. This approach allows us to infer
the energy independent of jet collimation. We find that for GRB 980703 the
kinetic energy at the time of the transition to non-relativistic evolution,
t_NR ~ 40 d, is E_ST ~ (1-6)e51 erg. For GRB 970508 we find E_ST ~ 3e51 erg at
t_NR ~ 100 d, nearly an order of magnitude higher than the energy derived in
Frail, Waxman and Kulkarni (2000). This is due primarily to revised
cosmological parameters and partly to the maximum likelihood fit we use here.
Taking into account radiative losses prior to t_NR, the inferred energies agree
well with those derived from the early, relativistic evolution of the
afterglow. Thus, the analysis presented here provides a robust,
geometry-independent confirmation that the energy scale of cosmological GRBs is
about 5e51 erg, and additionally shows that the central engine in these two
bursts did not produce a significant amount of energy in mildly relativistic
ejecta at late time. Furthermore, a comparison to the prompt energy release
reveals a wide dispersion in the gamma-ray efficiency, strengthening our
growing understanding that E_gamma is a not a reliable proxy for the total
energy.Comment: Submitted to ApJ; 13 pages, 6 figures, 1 table; high-resolution

Spin resonance induced by a mechanical rotation of a polariton condensate
We study theoretically the polarization dynamics in a ring-shape bosonic
condensate of exciton-polaritons confined in a rotating trap. The interplay
between the rotating potential and TE-TM splitting of polariton modes offers a
tool of control over the spin state and the angular momentum of the condensate.
Specific selection rules describing the coupling of pseudospin and angular
momentum are formulated. The resonant coupling between states having linear and
circular polarizations leads to the polarization beats. The effect may be seen
as a polariton analogy to the electronic magnetic resonance in the presence of
constant and rotating magnetic fields. Remarkably, spin beats are induced by a
purely mechanical rotation of the condensate
