Knowledge Graph Embedding for Hyper-Relational Data

引用

Tsinghua Science and Technology 2017年第2期22卷 185-197页

作者： Chunhong Zhang miao zhou Xiao Han Zheng Hu Yang Ji the State Key Laboratory of Networking and Switching Technology Beijing University of Posts and TelecommunicationsBeijing 100876China the Key Laboratory of University Witeless Communication Ministry of EducationBeijing University of Posts and TelecommunicationsBeijing 100876China

Knowledge graph representation has been a long standing goal of artificial intelligence. In this paper,we consider a method for knowledge graph embedding of hyper-relational data, which are commonly found in knowledge graphs. Previous models such as Trans（E, H, R） and CTrans R are either insufficient for embedding hyper-relational data or focus on projecting an entity into multiple embeddings, which might not be effective for generalization nor accurately reflect real knowledge. To overcome these issues, we propose the novel model Trans HR, which transforms the hyper-relations in a pair of entities into an individual vector, serving as a translation between them. We experimentally evaluate our model on two typical tasks—link prediction and triple *** results demonstrate that Trans HR significantly outperforms Trans（E, H, R） and CTrans R, especially for hyperrelational data.

Effect of protein on PVDF ultrafiltration membrane fouling behavior under different pH conditions： interface adhesion force and XDLVO theory analysis

引用

Frontiers of Environmental Science & Engineering 2016年第4期10卷 157-167页

作者： Xudong WANG miao zhou Xiaorong MENG Lei WANG Danxi HUANG School of Environmental and Municipal Engineering Xi'an University of Architecture and Technology Xi'an 710055 China School of Science Xi'an University of Architecture and Technology Xi'an 710055China

To further detem3ine the fouling behavior of bovine serum albumin （BSA） on different hydrophilic PVDF ultrafiltration （UF） membranes over a range of pH values, self-made atomic force microscopy （AFM） colloidal probes were used to detect the adhesion forces of membrane-BSA and BSA BSA, respectively. Results showed that the membrane-BSA adhesion interaction was stronger than the BSA-BSA adhesion interaction, and the adhesion force between BSA-BSA-fouled PVDF/PVA membranes was similar to that between BSA-BSA-fouled PVDF/PVP membranes, which indicated that the fouling was mainly caused by the adhesion interaction between membrane and BSA. At the same pH condition, the PVDF/PVA membrane-BSA adhesion force was smaller than that of PVDF/ PVP membrane-BSA, which illustrated that the more hydrophilic the membrane was, the better antifouling ability it had. The extended Derjaguin-Landau-Verwey Overbeek （XDLVO） theory predicts that the polar or Lewis acid-base （AB） interaction played a dominant role in the interracial free energy ofmcmbrane-BSA and BSA BSA that can be affected by pH. For the same membrane, the pH values of a BSA solution can have a significant impact on the process of membrane fouling by changing the AB component of free energy.

Fluid Flow and Interfacial Phenomenon of Slag and Metal in Continuous Casting Tundish With Argon Blowing

引用

Journal of Iron and Steel Research International 2008年第4期15卷 26-31页

作者： WANG Jun ZHU miao-yong zhou Hai-bing WANG Ying School of Materials and Metallurgy Northeastern University Shenyang 110004 Liaoning China

The fluid flow and the interfacial phenomenon of slag and metal in tundish with gas blowing were studied with mathematical and physical modeling, and the effects of gas flowrate, the placement of porous beam for the generation of bubbles, and the combination of flow control devices on the flow and slag-metal interface were investigated. The results show that the position of gas bubbling has a significant effect on the flow in tundish, and the placement of porous beam and gas flowrate are the two main factors affecting the entrapment of slag in tundish. The closer the porous beam to the weir, the more reasonable is the flow, which is in favor of the control of slag entrapment in tundish.

通过廉价、可再生的小麦秸秆制备吸油剂时,需要预处理来除去秸秆表面的蜡质和木质素组分,以暴露纤维素的羟基使其充分参与改性反应,达到增强秸秆的亲油疏水的目的。考察了小麦秸秆经氢氧化钠、亚氯酸钠和二者混合溶液等不同预处理溶剂对制得的吸油剂的吸油性能的影响。结果表明,NaOH处理后,制备的吸油剂水接触角可从80°增加到108.5°,油接触角则降为0°,表现出亲油和超疏水性,吸油性能大幅度提高。在此基础上对NaOH处理时间、温度和浓度进行对比,得出在100℃,5%,2 h预处理的效果最佳。
