... Please note the following problems and workarounds: . ... Arrow keys . Arrow keys are used in SAOtng to move the mouse or markers. ... Unfortunately, error messages are generated if both sets are defined in the SAOtng code but are not supported by X. To get around this problem, we have added the -kbprefix command switch (and the SAOTNG_KBPREFIX environment variable) to SAOtng. This switch allows you to specify which arrow keys you want to use (assuming your version of X supports both). ...

. filename : Cross-device link . The file you are trying to make a link to is located on a different physical device. The solution is to create a symbolic link . directory_name is a directory . You are trying to make a link to a directory. Check the pathname for the file. ln: filename : File exists . A file with the same name as the linkname already exists in the destination directory. Use a different name for the linkname.

Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

... LO frequencies were 1/2, 1/3 and 1/8 of signal frequency 75 GHz. ... But single junction SIS mixer has 30 dB input signal power range only [ll and it may decrease at high frequencies more than 200 GHz due to Josephson and 1 "switching" noise rise [2 e Our experiments show that subhurmonically pumped SIS mixer may have improved saturation power and reduced noise at high frequencies in some operation modes. ... 269 Fig.2 Quantum for LO and signal frequencies SIS operating mode. ...

Next: UNSOLVED PROBLEMS Up: OTHER HYDROGEN-DEFICIENT STARS Previous: Carbon stars . During the past century, three stars have been observed as being both hot subdwarfs and RCB stars at different times. V605Aql is now the hydrogen-deficient central star of a planetary nebula (Abell58). ... In 1996, an unremarkable faint blue star suddenly brightened and within three years had become a very cool and luminous carbon star, now known as Sakurai's Object or V4334Sgr ([ Nakano et al. ... 1999 ]). ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

Learning Astronomy Through Storytelling . That children at different stages of development will derive different meanings from the same story is obvious but worth mentioning. ... If you teach K-2, the central message of the story that you want students to understand is simply that the Moon's shape, as they see it in the sky, varies. ... Children learn that a story has a plot, a setting, characters, a main problem, a crisis point, and a solution. ...

... The goal of this course is to teach some basic methodologies for analysing problems of control of partial differential equations. ... When dealing with controllability problems, one has to distinguish between finite-dimensional systems modelled by ordinary differential equations and infinite-dimensional distributed systems described by means of partial differential equations. Most of this course deal with problems related with partial differential equations. ...

... I do have a problem with the realtime capabilities of Linux. I wrote a loadable driver which uses the RealTimeClock to generate periodic interrupt at a frequency of 1024Hz. With each interrupt the driver increments an internal counter. The 'read' function of the driver returns simply that counter. Next I wrote a realtime task (with the highest priority) which read that RTC continuously. This tasks checks if the read counter is incremented by one between two read calls. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
