摘要:
Composition and product for protecting external surfaces of leather and/or textile articles from multiple environmental factors, e.g., dirt and water. The composition includes (a) a solvent system including at least one linear C2-C6 alcohol solvent; (b) at least one oxide of metal or metalloid nanoparticles; and (c) an organosilicon component including one or more of a silicone oil, silicone wax, or silicone resin. Synergism exists between the nanoparticles and the organosilicon component. Together the nanoparticles and the organosilicon component provide ultimate performance, whereas when the organosilicon component is not present, loss of performance occurs. Preferably, the nanoparticles are present as a core structure with a polymeric coating. Preferably, the composition is contained in a non-aerosol storage and spray dispensing container and applied to an external surface of a finished leather and/or textile article by spraying.
摘要:
A system and computer-implemented method for accounting for temporal dispersion in low-order finite difference seismic wave propagation is disclosed. An embodiment of the method includes transforming a seismic dataset from time domain to frequency domain to obtain a frequency-domain seismic dataset, applying a frequency-domain time varying filter to the frequency-domain seismic dataset to obtain a filtered frequency-domain seismic dataset, and transforming the filtered frequency-domain seismic dataset from the frequency domain to the time domain to obtain a time-domain filtered seismic dataset. The frequency-domain time varying filter is based on the effective phase velocity inherent in a finite-difference solution to the wave equation.

A system and method for controlling soot regeneration in a catalyst soot filter ("CSF") (16) of an exhaust system (10) for a diesel engine (12) by measuring the inlet temperature of a diesel oxidation catalyst ("DOC") (14) coupled to the CSF (16), determining a target light off temperature for the DOC (14), injecting a first fuel amount into a cylinder of the engine (12) to cause the DOC (14) inlet temperature to approach the target light off temperature, measuring the CSF (16) inlet temperature and pressure across the CSF (16), determining a target CSF (16) inlet temperature for regeneration, injecting a second fuel amount for combustion in the DOC (14) to cause the CSF (16) inlet temperature to approach the target CSF (16) inlet temperature.

摘要:
Beamed data can be obtained from shot gather data, and debeamed data can be obtained from beamed data. Shot gather data for a geophysical volume of interest in a first domain and/or beamed data in a third domain may be received. The first domain has a component relating to seismic wave propagation time and a spatial component relating to lateral spacing. The third domain has a component relating to local plane wave arrival time at a beam center surface location and a component relating to plane wave arrival directions. Data may be transformed between the first domain and a second domain. The second domain has a frequency component and a spatial component corresponding to the spatial component of the first domain. Data may be weighted and/or deweighted in the second domain using a weighting function. A forward transform may be applied to weighted shot gather data in the first domain to obtain beamed data in the third domain. A reverse transform may be applied to beamed data in the third domain to obtain weighted debeamed data in the first domain.
摘要:
Seismic data representing the propagation of seismic energy through a geologic volume of interest is processed. The seismic energy propagates through the geologic volume of interest from one or more source locations at or near the geologic volume of interest to one or more detector locations at or near the geologic volume of interest. In processing the seismic data, the seismic energy is modeled as beams (e.g., Gaussian beams). The processing includes determining a filter for the seismic data that attenuates aliasing which may be present in the seismic data due to spacing between detector locations.
