20100190260 | METHOD FOR IDENTIFYING NAPHTHENATES IN A HYDROCARBON CONTAINING LIQUID - A method for quantifying the presence of naphthenic acids in a hydrocarbon-comprising liquid that includes: contacting a hydrocarbon-comprising liquid with gaseous ammonia; isolating a reaction product produced by the contacting step; and analyzing the reaction product for the presence of naphthenates using a mass spectrometry technique. The naphthenic acids known to form commercial naphthenate deposits can be (i) ions of tetraprotic carboxylic acids having molecular weights ranging from 1225 to 1270 Daltons, (ii) n-alkyl or branched carboxylic acids having molecular weights ranging from 250 to 650 Daltons, or (iii) both. | 07-29-2010 |
20090116595 | SYSTEM AND METHODS FOR DETERMINING MASKING SIGNALS FOR APPLYING EMPIRICAL MODE DECOMPOSITION (EMD) AND FOR DEMODULATING INTRINSIC MODE FUNCTIONS OBTAINED FROM APPLICATION OF EMD - A computer-implemented method of signal processing is provided. The method includes generating one or more masking signals based upon a computed Fourier transform of a received signal. The method further includes determining one or more intrinsic mode functions (IMFs) of the received signal by performing a masking-signal-based empirical mode decomposition (EMD) using the at least one masking signal. | 05-07-2009 |
20090091280 | STOCHASTIC ANTI-WINDUP PROPORTIONAL-INTEGRAL (PI) CONTROLLER - Different circuit-based implementations of stochastic anti-windup PI controllers are provided for a motor drive controller system. The designs can be implemented in a Field Programmable Gate Arrays (FPGA) device. The anti-windup PI controllers are implemented stochastically so as to enhance the computational capability of FPGA. | 04-09-2009 |
