Este artigo apresenta os conceitos básicos da terapia vibro-acústica, especificamente, aquela abordada pelo pesquisador e terapeuta norueguês Olav Skille. Além dos componentes que formam o arcabouço da vibro-acústica de Skille serão... more
All life on earth has developed within these earthly ‘Schumann Resonances’ as well as the ‘Inner and Outer’ Van Allen donut shaped energy toroid complex energy fields. When one calculates additional frequency relationships of the Van... more
Method and apparatus are provided for a non-invasive bubble measuring instrument operable for detecting. distinguishing, and counting gaseous embolisms such as bubbles over a selectable range of bubble sizes of interest. A selected... more
The dielectric properties and AC conductivity of Au/polyvinyl alcohol (Co, Ni-doped)/n-Si Schottky diodes (SDs) were investigated in the frequency range 1 kHz–1 MHz and in the temperature range 80–400 K. The frequency and temperature... more
The condition number of the matrix of electro-acoustic head-related transfer functions (HRTF) in a two-channel sound reproduction system has been used as a measure of robustness of the Atal-Schroeder (1962) crosstalk canceler. A... more
ABSTRACT The uncertainty of field measurements of a façade was evaluated by a Round Robin Test (RRT) conducted in a full-scale experimental building at the Construction Technologies Institute of the National Research Council of Italy... more
: Low (10 - 100 Hz) and very low (1 - 10 Hz) frequency acoustic propagation loss is predicted for a site on the Bermuda Rise near 30 deg N 69 deg W. An extensive survey of the open literature is reported, and a geo- acoustic model of the... more
