... The perceptron structure, on the basis of which the database is built, is defined by a number of the input and output parameters and a required accuracy. ... The output perceptron data are the expansion coefficients of the scattering matrix elements in series of the generalized spherical functions. ... As the cluster structure depends on the generation conditions the expansion coefficients were averaged over 5--7 realizations of the clusters (for N . ... is the coefficient number. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...

... 1997: . The parameters of the unique solar complex at the RATAN-600 were enhanced. ... A coude-echelle spectrometer of high and very high resolution was designed and manufactured for the 2-meter telescope (Terskol peak) with the simultaneous spectrum registration in a wide wavelength range ( 3500-10000 A ) by the CCD system. The spectrometer has three Schmidt cameras that enable spectral observations with the resolution of R = 45000, 90000, 180000. ... Archive . ...

Nikolay Gusev: Summary In many cases mathematical treatment of liquids is done in the framework of incompressible fluid. ... Therefore it is reasonable to study the equations of low compressible fluid motion, in particular, convergence of their solutions to the corresponding incompressible limit. To emphasize the fact that the fluid is low compressible one should introduce a parameter which represents a measure of compressibility. ... Regularity and uniqueness of the solutions in dimension 2. ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

Shell scripts can act like standard UNIX commands and take arguments from the command line. Arguments are passed from the command line into a shell program using the positional parameters $1 through to $9 . Each parameter corresponds to the position of the argument on the command line. ...
