Patent number: 8886362
Abstract: A power forecasting module determines a load forecast of a distribution system (DS) and a power generation forecast of distributed energy resources (DERs) A demand response (DR) module estimates an available DR based on the load and the power generation forecast and modifies the load forecast by dispatching an optimal DR. An energy storage commitment module determines a charging/discharging schedule of energy storage devices in the system based on the modified load profile and generates a second load profile by incorporating the charging/discharging schedule of energy storage devices. An unit commitment (UC) module determines a DER schedule of supplying electrical power to the loads in the second load profile based on a first objective function. An economic dispatch (ED) module determines an optimum operating point for each DER and an Integrated Volt-VAR Control (IVVC) module controls distribution assets to maintain a voltage profile in the system.

In one aspect, the method also includes modifying one or more subsequently acquired ultrasound signals that are communicated along the channels based on the crosstalk signal.

Patent number: 8877084
Abstract: A method for refreshing an acid bath solution includes determining a concentration of phosphoric acid in the acid bath solution and determining a concentration of hydrochloric acid in the acid bath solution. The method further includes calculating a volume of phosphoric acid to add to the acid bath solution to achieve a predetermined concentration of phosphoric acid in the acid bath solution. In addition, the method includes calculating a volume of hydrochloric acid to add to the acid bath solution with the volume of phosphoric acid to increase the acid bath solution to a predetermined volume, and adding the volume of phosphoric acid and the volume of hydrochloric acid to the acid bath solution.

Patent number: 8876481
Abstract: A turbine airfoil component assembly for use with a turbine engine including a attachment assembly having an inner surface defining a cavity. The attachment assembly includes a metal alloy substrate. An airfoil assembly is at least partially positioned within the attachment assembly and extends outwardly from the attachment assembly. The airfoil assembly includes a ceramic matrix composite (CMC) substrate. A reaction barrier coating is disposed over at least a portion of the airfoil assembly. The reaction barrier coating is positioned between the attachment assembly and the airfoil assembly.

Patent number: 8878135
Abstract: A neutron scintillator composite (NSC) is made of a neutron scintillator and a binder. The neutron scintillator of the composite has the formula LiyMgBry+2, where y=2, 4 or 6 and may further comprise cerium as a scintillation activator. The binder of the composite has an index of refraction substantially identical to that of the neutron scintillator. The neutron scintillator and binder are mixed into a solid or semi-solid neutron scintillator composite having sufficient flowability for molding into a shaped article, such as a neutron sensing element of a radiation detector. The neutron scintillator composite collects and channels photons through the material itself and into a photosensing element optically coupled to the composite. Because the indices of refraction for both the neutron scintillator and the binder are substantially identical, scattering at the scintillator-binder interface(s) is minimized, thereby producing transmission efficiencies that approach single crystals.

Patent number: 8878126
Abstract: Substances on or adjacent a tubular disposed in a subterranean wellbore can be detected and/or their presence identified by monitoring gamma rays scattered from the substances. The substances include deposits on a sidewall of the tubular and liquid contained in the tubular. Examples of the deposits include asphaltenes, paraffins, scale, sand, and the like. Gamma rays are strategically directed from a tool disposed within the tubular and to adjacent a sidewall of the tubular. Some of the gamma rays scatter from the substances adjacent the tubular and are detected with detectors set a designated axial distance from the gamma ray source.

Patent number: 8878923
Abstract: In an imaging device having an objective and a stage for holding a sample to be imaged, a method for autofocusing is presented. The method includes determining a measured focus value corresponding to at least a first of a plurality of logical image segments. Further, the method includes imaging the first logical image segment using the measured focus value. The method also includes determining a predicted focus value for a second of the plurality of logical image segments using the measured focus value and a stored focus variation parameter. In addition, the method includes imaging the second logical image segment using the predicted focus value.
