Abstract: Provided is a method for measuring surface characteristics of at least a portion of an object, including providing a light source; generating a first interference pattern on the at least a portion of the object; capturing an image of the first interference pattern; shifting the phase of the light source to generate a second interference pattern; capturing an image of the second interference pattern; filtering distortion from the interference patterns; extracting a wrapped phase of the at least a portion of the object based on the images; unwrapping the wrapped phase of the at least a portion of the object to generate an unwrapped phase; identifying a computed depth map distance to the at least a portion of the object; and fitting an ideal part to the computed depth map of the at least a portion of the object to measure the surface characteristics.

Abstract: The present invention is directed to a ligated metal-organic framework (MOF) for use in removing both anionic and cationic species from a liquid or liquid stream. The present invention also provides methods for placing the MOF on a substrate to form a MOF-containing product that can be used in the removal of certain species from a given fluid. The MOF may be a Zr-based MOF, such as NU-1000, for removal of certain anions, such as oxy-anions, or having an attached thiosulfonyl-thiol (—SO2—S—R2—SH, where R2 is an alkyl group) ligand for complexation with certain cationic species in addition to the anions. The substrate may be any substrate to which a given MOF may be attached, including inert polypropylene polymer resin beads, a macroscopic fabric such as a mesh material or mesh filter, and a molecular fabric.

Abstract: The present invention provides for the use of a metal-organic framework (MOF) in removing particular chemical species or compounds, in particular oxy-anions of iodate, from a liquid or liquid stream. In some embodiments, the MOF is a Zr-based MOF, such as NU-1000 or MOF-808. The Zr-based MOF, including NU-1000 or MOF-808 can be used to remove these oxy-anions from various liquid streams or liquids in industrial processes such as a nuclear and fossil fuel power plants.

Abstract: A method for detecting blowout precursors in at least one gas turbine combustor comprising: receiving combustion dynamics acoustic data measured by an acoustic measuring device associated with the combustor in real time; performing wavelet analysis on the acoustic data using simplified Mexican Hat wavelet transform analysis; and determining the existence of a blowout precursor based at least in part on the wavelet analysis. Provided also is a system and a non-transitory computer readable medium configured to perform the method.

Abstract: An in-situ incremental reheating system configured to increase steam temperature and thermodynamic efficiencies of a steam turbine is disclosed. The system includes a pump; a radiant heater; piping inter-connecting the pump, radiant heater and steam turbine to create a flow circuit; and a heat transfer material configured to flow through the flow circuit and transfer heat directly to steam used in the steam turbine. The pump moves the heat transfer material through the flow circuit and the radiant heater regenerates the heat transfer material after the heat transfer material transfers heat to the steam.
