Sound Absorption and Sound Power Measurements in Reverberation Chambers Using Energy Density Methods
Measurements in a reverberation chamber use spatially averaged squared pressure to calculate sound absorption, sound power, and other sound measurements. While a reverberation chamber provides an approximation of a diffuse sound field, variations in the measurements introduce uncertainty in …

Study of the effects of roughness, ultraviolet radiation, multipactoring and magnetic field on vacuum breakdown
Breakdowns in vaccuum and the factors a ffecting them have been studied for more than a hundred years, with applications ranging from high voltage isolation to space propulsion. In current thermonuclear fusion projects, one of the methods of heating the plasma is through ion cyclotron …

Investigation of the Volga River sediments composition : inorganic pollutants of potential concern
Within the framework of the joint Russian-German research project "Volga-Rhine", a continuation of the scientific-technical cooperation started with the "Oka-Elbe"-project in 1992, investigations of the inorganic (this report) and organic pollution (conducted by the working group of Prof. H.F. …

ORGANIC MICROPOLLUTANTS ANALYSIS AND THEIR METROLOGICAL TRACEABILITY TO SI UNITS
The PhD activity described in the present work concerned the determination of organic micropollutants in food matrices at trace level, with the aim of correctly evaluating the measurement uncertainty and establishing metrological traceability for the results of these measurements. The metrological …
