ABSTRACT

Temporal content of parietal pressure and electrical resistance tomography measurements are compared and prove to be different. Tomographic signals may be represented by a one parameter autoregressive process which is directly related to the gas flow superficial velocity

Keywords Bubble column, electrical resistance tomography, pressure fluctuations, linear processes
