Abstract:
A method of estimating chordal holdup values of gas, oil, and water (εG, εO, εW) for tomographic imaging of a three-phase flow through a volume, including: providing an X-ray source for irradiating through said volume and X-ray sensors for discriminating between a first and a second radiation bands, conducting first calibration measurements (IGS, IOS, IWS) of said first radiation band, conducting second calibration measurements (IGH, IOH, IWH) of said second radiation band, arranging a mixture of two or more fluids, irradiating said volume and conducting X-ray measurements (IS, IH) in said radiation bands, establishing a relationship between a function of holdup values f(εG, εW) of at least gas and water and said X-ray measurements (IS, IH), searching holdup values (εG, εW) that minimize said function of holdup values f(εG, εW) under the constraints of the sum of said holdup values is more than or equal to zero and less than or equal to one, i.e. that 0≦εG+εW≦1.

Abstract:
Improved mask layout patterns are described for closely spaced primitives in phase shift photolithography masks. In one example, at least a portion of a photolithography mask layout is decomposed into primitives. Jogs are identified from among the primitives, the jogs being characterized by three adjacent corners. E-fields are determined for the identified jogs and are applied to synthesize an electric field at a substrate. The mask layout is corrected using the synthesized electric field and a printed wafer pattern is calculated.

Abstract:
The present invention relates to a method and system for automatically identifying various information of a train. The method comprises using sensors to collect wheelbase information, processing the information by signal data processing devices, thereby providing information of a train, namely: arranging a plurality of sensors along the rail in the incoming direction of the train, dividing the sensors into at least three groups, each group comprising at least two sensors; analyzing and processing the signal data stream obtained from the sensors and collected when a train vehicle passes by, thereby acquiring the speed and wheelbase of the train, and further acquiring the train segmentation information; determining the vehicle type; acquiring hook locating information; determining the train arrival; determining the train departure; acquiring vehicle number. The present invention further comprises a system for carrying out the information method for automatically identifying information of a train. The present invention can provide a plurality of types of train information with high accuracy, and is easy to be carried out.
Abstract:
Described herein is mask design and modeling for a set of masks to be successively imaged to print a composite pattern on a substrate, such as a semiconductor wafer. Further described herein is a method of double patterning a substrate with the set of masks. Also described herein is a method of correcting a drawn pattern of one of the mask levels based on a predicted pattern contour of the other of the mask levels. Also described herein is a method of modeling a resist profile contour for a mask level in which photoresist is applied onto a inhomogeneous substrate, as well as method of predicting a resist profile of a Boolean operation of two masks.

Abstract:
A writing system includes a pen with a two-dimensional optical sensor and a three dimensional acceleration sensor positioned to indicate movement of the pen. A calibrator is coupled to receive path coordinate signals from the two-dimensional optical sensor and the three dimensional acceleration sensor. The calibrator and the two-dimensional optical sensor and the three dimensional acceleration sensor are configured to operate in one of two modes, a contactable mode of operation wherein both the two-dimensional optical sensor and the three dimensional acceleration sensor supply path coordinate signals to the coordinator and a contactless mode of operation wherein only the three dimensional acceleration sensor supplies path coordinate signals to the coordinator.
