摘要： The present disclosure relates to a downhole rotating magnetic field generator, wherein a stator assembly is formed by fixedly connecting a guiding stator, windings, and a body together, and a rotor assembly is formed by mounting a turbine rotor and a permanent magnet together. Between the stator assembly and the rotor assembly, sliding bearings are arranged and small mud passages are formed. There is no metal isolation between the rotor and the stator for cutting through the magnetic lines of force, so that the eddy current loss is relatively small. Meanwhile, with mud flowing through the passages as lubricant, overheating of the generator can be prevented and high power output can be ensured.

摘要： Compositions and methods for amorphous high temperature polyketone polymers incorporating 2H-benzimidazol-2-one with dihalobenzophenone and bis(halobenzoyl)benzene as comonomer units are described herein. The polyketones polymers have advantageous properties, particularly in terms of high glass transition temperatures (Tg), inherently flame resistance, good mechanical properties at elevated temperature, chemical resistance and dimensional stability in wet environment. The polymers are suitable for manufacturing high temperature molded systems and other articles of manufacture via injection molding, extrusion, compression molding, coating, blow molding, thermoforming, rotational molding and additive manufacturing.

摘要： Some aspects provide determination of a function to rectify functional differences between netlist G1 and netlist G2 having inputs V. The determination may include determination of a signal s of netlist G1 that can be re-synthesized so as to correct the functional differences between netlist G1 and netlist G2, assignment of respective static values to a first plurality of inputs V, assignment of respective initial values to a second plurality of inputs V, determination of a first function based on the assigned static values, the assigned initial values, a first error function reflecting the difference between outputs of netlist G1 and netlist G2 for each vector of inputs V in a case that s equals 0, and a second error function reflecting the difference between the outputs of netlist G1 and netlist G2 for each vector of inputs V in a case that s equals 1. Also included may be determination of whether the first function rectifies the functional differences between netlist G1 and netlist G2, assignment, if it is determined that the first function does not rectify the functional differences, of respective next values to the second plurality of inputs, and determination of a second function based on the first function, the assigned static values, the assigned next values, the first error function, and the second error function.

摘要： A method for modeling a circuit design includes synthesizing the circuit design to create a first gate-level representation of the circuit design. The method also includes analyzing a second gate-level representation of the circuit design to learn architecture information, and resynthesizing the first gate-level representation of the circuit design to incorporate the learned architecture information from the second gate-level representation of the circuit design. A computer-readable storage medium has stored thereon computer instructions that, when executed by a computer, cause the computer to synthesize a circuit design to create a first gate-level representation of the circuit design. The computer instructions also cause the computer to analyze a second gate-level representation of the circuit design to learn architecture information, and resynthesize the first gate-level representation of the circuit design to incorporate the learned architecture information from the second gate-level representation of the circuit design.
