20150368379 | SYNTHESIZING HYPERBRANCHED POLYMERS WITH UNIFORM STRUCTURE IN CONFINED SPACE - Hyperbranched polymers are synthesized with uniform structure based on one pot polymerization technique in confined space with nanometer scale, e.g. micelles in a microemulsion system. The segregated space in micelles or polymerizing nanoparticles is expected to regulate the growth of hyperbranched polymers by confining polymer-polymer reaction inside each individual locus. The obtained hyperbranched polymers have uniform size, similar to the size of nanoparticles, as indicated by a narrow molecular weight distribution of the polymers. | 12-24-2015 |
20100054394 | METHOD AND SYSTEM FOR IMAGE RECONSTRUCTION - A method and system for image reconstruction of data acquired by a device such as computed tomography is provided. The method and system use a multi-stage statistical iterative reconstruction techniques to provide a three dimensional representation of the scanned object. In one embodiment, the first stage uses a projection-based reconstruction technique, such as Ordered Subset (OS) to converge on a solution for low frequency portion of the image. A subsequent stage uses a voxel-based reconstruction technique, such as Iterative Coordinate Descent (ICD), to converge on a solution for high frequency portions of the image. Systems and methods for reconstructing images from incomplete or partial projection data is also provided. | 03-04-2010 |
20090065064 | COMPRESSOR TIP GAP FLOW CONTROL USING PLASMA ACTUATORS - A plasma generator for delaying the onset of rotation stall by tip gap flow control in, for example, an axial flow compressor is disclosed. The tip gap flow control system includes a housing surrounding a rotor of blades and having an inner wall. At least one plasma generating device is coupled to the inner wall of the housing and circumscribes at least a portion of the rotor of blades. A power supply is electrically coupled to the plasma generating device such that when the power supply energizes the plasma generating device, the axial momentum of a fluid flow between the inner wall of the housing and the tips of the rotor of blades in increased in the direction of the fluid flow. | 03-12-2009 |
