select * from tbl TABLESAMPLE system (5)
The SYSTEM method is significantly faster than the BERNOULLI method when small sampling percentages are specified, but it may return a less-random sample of the table as a result of clustering effects.
Unglaublich, was für ein absurdes Zeug zur Zeit durch die Medien und die Juristenblogs blubbert – weil der gleiche Unsinn im Referentenentwurf zum Leistungsschutzrecht (LSR) steht.
Imagers based on focal plane arrays (FPA) risk introducing in-band and out-of-band spurious response, or aliasing, due to undersampling. This can make high-level discrimination tasks such as recognition and identification much more difficult. To overcome this problem, three-chip color charge coupled device (CCD) cameras typically offset one CCD by 1/2 pixel with respect to the other two. Analogously, monochrome imagers including infrared can use microscan (or dither) to reduce aliasing. This...
