  • Publication number: 20250167640
    Abstract: A common mode line-to-ground filter is disclosed which includes but is not limited to a resistor, capacitor and a ground. The common mode line to ground filter is connected on a high side of a step-up transformer. A low side of the step-up transformer is connected to a variable frequency drive that provides a semi-sinusoidal voltage waveform. The common mode line to ground filter generates a filtered sinusoidal waveform from the output of the step-up transformer. The filtered sinusoidal voltage waveform is supplied via an electrical cable to an electrically submersible pump deployed downhole.

  • Publication number: 20250057424
    Abstract: Various examples are provided related to dynamic brain parcellation. In one example, a method for functional task prediction with dynamic supervoxel parcellation includes preprocessing activation data obtained from brains of multiple subjects to generate one or more dynamic parcellated supervoxel maps of the brain, the activation data associated with a functional task, and determining an anatomical location of the functional task in the brain of another subject based upon classification of supervoxels of the one or more dynamic parcellated supervoxel maps. In another example, a system includes at least one computing device that can preprocess activation data to generate one or more dynamic parcellated supervoxel maps of the brain, the activation data associated with a functional task, and determine an anatomical location of the functional task based upon classification of supervoxels of the one or more dynamic parcellated supervoxel maps.

  • Patent number: 7495044
    Abstract: A biodegradable polymer is disclosed having the composition g) from 8 to 80% by weight of a starch modified to include an hydroxyalkyl C2-6 group or modified by reaction with an anhydride of a dicarboxylic acid, preferably hydroxypropylated high amylose starch, a) from 0 to 87.9% of starch, b) from 4 to 11% by weight of a water soluble polymer selected from polyvinylacetate, polyvinyl alcohol and copolymers of ethylene and vinylalcohol which have a melting point compatible with the molten stat of the starch components, c) from 0 to 20% by weight of a polyol plasticiser, preferably glycerol, d) from 0.1 to 1.5% by weight of a C12-22 fatty acid or salt, preferably stearic acid and, e) 0 to 12% added water. The polymers are suitable as biodegradable rigid sheet or flexible film materials for use in packaging foodstuffs.
