Patent number: 10387386Abstract: Methods and a system are provided. A method includes automatically detecting, by an attribute structural variation detector, attribute structural variations in record schemas of a database lacking schema enforcement. The automatically detecting step includes encoding, by an encoder, nodes in the record schemas based on respective updated node labels to obtain a plurality of codes. The automatically detecting step further includes clustering, by a clusterer, the plurality of codes into one of a used category and an unused category. The used category and the unused category respectively consist of any of the plurality of codes used or unused to update a child label. The automatically detecting step also includes, when an intersection set formed from the used and unused categories has at least one member, retrieving, by the attribute structural variation detector, the at least one member as a structural variation between at least two of the record schemas.Type: GrantFiled: August 11, 2015Date of Patent: August 20, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Zhao Cao, Ju Wei Shi, Chen Wang, Lanjun Wang, Shuo Zhang

Patent number: 10049172Abstract: Changes in capillary pressure and relative permeabilities in reactive transport codes or reservoir simulators are formed by computer modeling. Based on continuum-scale hydraulic properties, the pore size distribution (PSD) is determined from a capillary pressure curve using the capillary tube concept. Changes in mineral volume through equilibrium or kinetic mineral reactions are then translated to changes in pore radii of the pore size distribution by selectively changing the radii of water occupied pores. The resulting new pore size distribution is converted back to an updated capillary pressure curve, which is then used for determining and forming models of total permeability and relative permeabilities at the continuum scale.Type: GrantFiled: December 10, 2015Date of Patent: August 14, 2018Assignee: Saudi Arabian Oil CompanyInventors: Shuo Zhang, Huihai Liu

Publication number: 20180013384Abstract: Disclosed is a temperature-compensated crystal oscillator based on analog circuit; a closed-loop compensation architecture determines the temperature compensation of a crystal oscillator. The power splitter divides the VCXO's current output signal with frequency f=f0+?f into two signals, one signal to output of the TCXO and the other signal is sent to an analog frequency-voltage conversion circuit. According to the frequency of the VCXO's current output signal, the analog frequency-voltage conversion circuit produces a voltage signal V(T), which corresponds to current ambient temperature. The difference between V(T) and a reference voltage signal Vref is produced and amplified to obtain a compensation voltage signal ?V through a voltage matching circuit. ?V is smoothed by a filter, then sent to the voltage control terminal of the VCXO to make the VCXO generate a stable signal with desired frequency f0, to compensate the frequency of the VCXO's output signal when the ambient temperature is changed.Type: ApplicationFiled: September 21, 2017Publication date: January 11, 2018Applicant: UNIVERSITY OF ELECTRONIC SCIENCE AND TECHNOLOGY OF CHINAInventors: Feng TAN, Duyu QIU, Peng YE, Jiquan CHEN, Lianping GUO, Hao ZENG, Shuo ZHANG, Ke TANG

Patent number: 9853523Abstract: An electric wheel motor cooling system includes first and second electric wheel motors and gear reducers which use hydraulic fluid for cooling and lubrication. Each of the electric wheel motor housings includes a sump and a scavenge pump for return of hydraulic fluid to the hydraulic fluid reservoir. A remotely located hydraulic pump interconnected with the hydraulic fluid reservoir supplies and powers first and second locally located hydraulic motors which supply the electric motors and gears with an equal flow of lubricating and cooling oil. The first and second hydraulic motors, in turn, drive a common output shaft which, in turn, drives first and second scavenge pumps. The first and second scavenge pumps have a higher fluid flow rate than the hydraulic motors ensuring that oil is removed from the first and second electric wheel motor housings thus eliminating any churning losses of the motors or gears.Type: GrantFiled: August 29, 2015Date of Patent: December 26, 2017Assignee: FAIRFIELD MANUFACTURING COMPANY, INC.Inventors: LaVerne Andrew Caron, Shuo Zhang, Keith Mears
