... The efficiency of SHG conversion about 9% for focused laser radiation was experimentally obtained. The scheme of dual-wave femtosecond optical heterodyne measuring instrument (optical coherent tomograph), which uses either fundamental wave (1.25 mkm) or SHG wave (0.625 mkm) of femtosecond Cr:forsterite laser was developed. ... The mean photon's lifetime in paper of 90-mkm thickness was obtained ( 0=2.14 ps for 1.25 mkm wavelength and 0=7.8±2,1 ps for 0.625 mkm wavelength). ...

... We introduce a new approach to database disk buffering, called the LFU-K method. The LFU-K page replacement algorithm is an improvement of the Least Frequently Used (LFU) algorithm. A probability-theoretical model for a formal description of the LFU-K algorithm is proposed. ... As we demonstrate with trace-driven simulation experiments, the LFU-2m algorithm performs better than the conventional buffering algorithm for the shared-nothing database system workloads. ...

. This diagram illustrates how a background image may be repeated within the content and padding areas of a box. In this example, a background image is first centered within a box (established by the BODY element of the example). The box contains paragraphs of text, shown in gray to make them discrete. The image, a blue wavy line on a pale yellow background, is then repeated vertically, to the top and bottom of the BODY box. The effect is to create a wavy band down the center of the page. Return to image.
