Diskrete Mathematik für Einsteiger on a sample. This effect was discovered by A. G. Bell in 1880, who observed that audible sound is produced when chopped sunlight is absorbed by a sample. Although the OA effect is very old, there is a great resurgence of interest in it in the past several years, both theoretically and experimentall

https://doi.org/10.1007/978-3-8348-9182-2out a decade ago. Following some early publications on this subject , a massive effort was undertaken in order to evaluate the potential of spontaneous Raman scattering in the important areas of atmospheric sounding and combustion diagnostics. In these experiments, the concentrations of the mol

Diskrete Mathematik für Einsteigers. The following examples can give an idea of the problems involved in the understanding and controlling the combustion processes. Pollutants in the exhaust gases have to be measured at trace level and the results of highly sophisticated computer codes, for chemical kinetics and turbulent combustion
