How do I report problems I've encountered using NEdit ? ... If you have a problem which is not covered in the on-line help, in this FAQ, or in the README file specific to your system, you can report it to discuss@nedit.org (usage questions) or, develop@nedit.org (error reports). ... Below are some suggestions for information you can provide to help in diagnosing your problem. ... As of version 5.2 a summary with build information is present under 'Version' in the Help menu. ...

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. ...

... 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). ...

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. ...

... 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 RCB carbon abundance remains an enigma ([ Asplund et al. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ... Since the predominant continuum absorber in RCB atmospheres is neutral carbon, it has not yet proved possible to measure the carbon abundance from carbon absorption lines. ...
