摘要:
A non-separable multiresolution structure based on frames by radial scaling functions is disclosed, which are minimally supported in the frequency. Resulting frame multiwavelets are also disclosed which can be isotropic. The construction can be carried out in any number of dimensions and for a variety of dilation matrices.
摘要:
A method and system for solving the inverse acoustic scattering problem using an iterative approach with consideration of half-off-shell transition matrix elements (near-field) information, where the Volterra inverse series correctly predicts the first two moments of the interaction, while the Fredholm inverse series is correct only for the first moment and that the Volterra approach provides a method for exactly obtaining interactions which can be written as a sum of delta functions.

Methods and apparatus are presented for precise measurement of mechanical position comprising combination of a plurality of coarse position signals to obtain substantial cancellation of spatial harmonics, generating a digital course position from a resolver system responsive to non-time harmonic signals, and providing precise incremental position signals from memory locations addressed by digital coarse position words.
摘要:
A process for depositing a thin film of a transition metal nitride, e.g., titanium nitride, on a substrate is provided. The vapors of a transition metal organometallic coompound or a transition metal amido compound are mixed with ammonia gas and allowed to react near a substrate heated to a temperature in the range of 100.degree. C. to 400.degree. C., resulting in deposition of a film on the substrate.
摘要:
Embodiments of an emulsion stability probe generally include two opposing electrodes with a gap there between, one or more electrical circuitry devices embedded in a probe assembly, and electrical circuitry devices that function to quantify and manipulate a sensed current signal, wherein the manipulated signal can be transmitted to an emulsion stability meter. Embodiments of an in-line emulsion stability measurement system generally include an electrical stability probe equipped with a process-connectable fitting, wherein attachment of the electrical stability probe to a process piping segment, utilizing the fitting, provides the electrodes and gap at least partially within the process piping segment, and whereby an in-line emulsion stability measurement of process fluid disposed within the piping segment may be performed. Methods of performing an emulsion stability measurement in-line and/or using an embodiment of the emulsion stability probe disclosed herein are also provided.
摘要:
A circuit includes a first input terminal for receiving a first pulsed voltage and a second input terminal for receiving a second pulsed voltage. The circuit further includes a load and an LC filter. The LC filter includes a coupled inductor pair that includes a first winding and a second winding magnetically coupled to each other. The first winding is coupled between the first input terminal and the load, and the second winding is coupled between the second input terminal and the load. A frequency of a first current flowing through the first winding is increased by the second pulsed voltage applied to the second winding.

摘要:
A laser device includes a plurality of lasers that includes a first laser and a second laser. The laser device further includes a drive circuit configured to apply a pulsed current to the first laser at a first phase. The drive circuit is further configured to apply the pulsed current to the second laser at a second phase. The first phase and the second phase are different. A total voltage provided to the plurality of lasers during a period between the first and second phases is substantially smaller than a sum of individual voltages provided to the plurality of lasers, respectively, during a pulse period of the pulsed current.
