Publication number: 20250131553Abstract: Since defect areas in collected hydro turbine defect images account for a small proportion and there is a significant color difference between surrounding background and defects, which creates too much redundant information and greatly affects detection speed, a method for detecting defects in a hydro turbine top cover based on an improved YOLOv8 model involves first cropping collected defect images to obtain cropped images, then expanding the cropped images by image enhancement techniques such as image flipping and image blurring to obtain a training dataset. A defect detection network based on YOLOv8-CBAM is constructed and trained to generate a defect detection model for detecting the defects in the hydro turbine top cover. The method achieves high precision in defect detection for the hydro turbine top cover.Type: ApplicationFiled: September 21, 2024Publication date: April 24, 2025Inventors: Tao Wu, Zaiming Geng, Ming Ma, Jian Deng, Wei Qiu, Hui Liu, Jiahao Zhang, Jie Yang, Xiangyou Ye, Xiaoping Zhang, Yiming Ren

Publication number: 20230174743Abstract: This invention is based upon the unexpected discovery that rice husk ash silica (synthetic amorphous silica from rice husk ash) provides an exceptionally good combination of properties when used in certain tire tread rubber formulations, such as an excellent combination of traction, tread-wear, and rolling resistance. These tread rubber formulations are comprised of a blend of high cis-1,4-polybutadiene rubber and a solution styrene-butadiene rubber which is preferably functionalized with amine groups, siloxy groups, thiol groups, carboxyl groups, or groups that are reactive with hydroxyl groups present on the precipitated rice husk ash silica. The use of such rice husk silica as a reinforcing-filler in rubber formulations is also highly desirable because such silica is a sustainable resource (bio-renewable) which is derived from an agricultural waste material which would otherwise be discarded as an undesirable waste product.Type: ApplicationFiled: November 30, 2022Publication date: June 8, 2023Inventors: Bruce Raymond Hahn, George Jim Papakonstantopoulos, Xiaoping Yang, Kuo-Chih Hua

Patent number: 10996003Abstract: A loop heat pipe with a vapor-liquid two-phase flow injector, including: an evaporator, the vapor-liquid two-phase flow injector, a boiling pool and a condenser. The two-phase flow injector has a central vapor inlet and a circumferential liquid inlet, and is connected to an outlet of the evaporator and an inlet of the boiling pool. The condensate inlet of the condenser is connected to an outlet of the boiling pool. An outlet of the condenser is connected to the evaporator. With the vapor-liquid two-phase flow injector, the invention can directly introduce a part of the supercooled liquid working medium to the boiling pool without passing through the evaporator, solving the problem of insufficient liquid supply for the boiling pool and increasing the driving force for the system operation. Therefore, the invention enables the efficient cooling of electronic devices and the long-distance heat transfer.Type: GrantFiled: September 29, 2019Date of Patent: May 4, 2021Assignee: Xi'an Jiaotong UniversityInventors: Jinjia Wei, Xiaoping Yang, Lei Liu, Jie Liu
