Abstract: A device for determining an estimated value for a mean power of the noise-signal sequence, which is superposed on an undisturbed periodic transmitted-signal sequence, determines a mean power of a received-signal sequence, which corresponds to the undisturbed periodic transmitted-signal sequence with the addition of the superposed noise-signal sequence. It then estimates an estimated-signal sequence for the undisturbed periodic transmitted-signal sequence from the received-signal sequence. Following this, a mean power of the estimated-signal sequence and the estimated value of the mean power of the noise-signal sequence is determined from a difference between the determined mean power of the received-signal sequence and the determined mean power of the estimated-signal sequence.

Abstract: In order to determine a volume thermal expansion coefficient of a liquid, a sample of the liquid is placed inside a cell of a calorimeter followed by an incremental increase of pressure inside the cell containing the liquid. After each pressure increase heat flow into the cell and volume of the liquid are measured. Based on results of the measurements of the heat flow and accounting for initially evaluated cell volume, the volume thermal expansion of the liquid is determined.

Abstract: A technique facilitates the monitoring of thermodynamic properties of reservoir fluids. The technique utilizes a modular sensor assembly designed to evaluate a sample of a hydrocarbon-containing fluid within a cell body. A variety of sensors may be selectively placed into communication with a sample chamber within the cell body to evaluate the sample at potentially high pressures and temperatures. The sensors may comprise a density-viscosity sensor located in-situ to efficiently measure both the density and viscosity of the sample as a function of pressure and temperature. Other sensors, such as an optic sensor, may also be positioned to measure parameters of the sample while the sample is retained in the sample chamber.
