Одной из самых известных задач в этой области, мотивировавшей многочисленные исследования в течение уже более чем века, является 16-я проблема Гильберта, а точнее вторая ее часть. В ней требуется найти верхние оценки на число предельных циклов полиномиальных векторных полей на плоскости. 16-я проблема не решена до сих пор, даже в случае квадратичных векторных полей. ... Векторные поля и поля направлений на плоскости и на сфере. ...

When using a large number of Virtual Hosts, Apache may run out of available file descriptors (sometimes called file handles if each Virtual Host specifies different log files. ... Unix operating systems limit the number of file descriptors that may be used by a process; the limit is typically 64, and may usually be increased up to a large hard-limit. ... If you system falls into 1 or 2 (above), then increase the file descriptor limit before starting Apache, using a script like #!/bin/sh . ...

Whilst no radio emission was detected from any of the targets, significant upper limits were placed on the radio luminosities that are below the luminosities of previously detected ultracool dwarfs. Combining our results with those from the literature gives a detection rate for dwarfs in the spectral range M7 тАУ L3.5 of тИ® 9%. ...

... Limit of star magnitude. If you want to obtain best results, you should use reference stars not more dimly than limiting star magnitude of your telescope. Limiting star magnitude depends on time of an exposition also.) This value should be set as " maximum of star magnitude " in a dialog box " Extraction from catalogue". To find darkest stars in the frame, make the following: . ... Two star magnitudes (m1, m2 in two photometric systems) will be outputted in the window "Information". ...

The upper limit to stellar masses is unclear, as is the relative importance of nature (stellar physics) and nurture (formation environment) to the limit. ... Despite some uncertainties in the linear growth rate, we conclude that these modes saturate nonlinearly at small and harmless amplitudes. Vigorous, optically thick winds driven by the Rosseland-mean opacity near 100,000 K are more likely to limit the main-sequence lifetime. ...

... 3. mJy for ; . ... These criteria were chosen in order to ensure that a well defined, flux-limited sample can be achieved. ... The slightly different radio flux limits north and south of the equator are simply explained: For (and , the limit of the GB6 catalog), it is easy to see that all sources with mJy (the limit of the NORTH20CM catalog) and will be above the much lower flux limit of the GB6 catalog ( mJy; note that the converse does not hold). ...

Slew limit control to protect the telescope and hardware is not completely implemented in softare. This system is not recommended for unattended operation unless safety limit switches are installed that will stop motion that could exceed the telescope's mechanical constraints. We use a tilt switch on the OTA and mechanical limit switches on the RA axis to prevent motions that would go beyond safe limits. ...
