Downhole working conditions analysis and drilling complications detection method based on deep learning
Wang, Chao; Liu, Gonghui; Yang, Zhirong; Li, Jun; Zhang, Tao; Jiang, Hailong; Cao, Chenguang (Peer reviewed; Journal article, 2020)Drilling complications, which are usually hard to be discovered in time using the traditional surface detecting methods, result in much time and money wasted in handling these problems. Restricted to data transmission speed ... -
A Hybrid Data-Driven Metaheuristic Framework to Optimize Strain of Lattice Structures Proceeded by Additive Manufacturing
Zhang, Tao; Sajjad, Uzair; Sengupta, Akash; Ali, Mubasher; Sultan, Muhammad; Hamid, Khalid (Peer reviewed; Journal article, 2023)This research is centered on optimizing the mechanical properties of additively manufactured (AM) lattice structures via strain optimization by controlling different design and process parameters such as stress, unit cell ... -
Non-uniform Temperature Distribution's Impact on Downhole Weight on Bit Measurement (DWOB) and the Novel Compensatory Method
Wang, Chao; Liu, Gonghui; Li, Jun; Zhang, Tao; Yang, Zhirong; Jiang, Hailong; Ren, Kai; Wu, Zhe (Peer reviewed; Journal article, 2020)Non-uniform temperature distribution of DWOB measuring devices has a great effect on the accuracies of weight on bit (WOB) readings. To study the influence, two types of non-uniform temperature distributions of the WOB ... -
One-pot Conversion of Biomass to Ethylene Glycol, Propylene Glycol and other Polyols over Carbon Supported Tungsten Catalysts
Bjørgen, Cecilie (Master thesis, 2013)Tungsten carbide and nickel promoted tungsten oxide catalysts supported on CNTs and AC were prepared for the catalytic conversion of cellulose towards polyols, particularly EG. Incipient wetness impregnation was used for ... -
One-Pot Conversion of Cellulose to Ethylene Glycol and Propylene Glycol over Nickel Zinc Oxide Catalysts with CNT Support
Liland, Ingvild Skeie (Master thesis, 2013)Ni-Zn oxide catalysts with CNT support were prepared by the pechini method, and evaluated for the conversion of cellulose to polyols. The catalysts were characterized by XRD, SEM/TEM, N2 adsorption, temperature programmed ... -
Robust duality and saddle point characterizations for nonconvex multiobjective optimization with data uncertainty
Chen, Jiawei; Yang, Ruixi; Köbis, Elisabeth Anna Sophia; Zhang, Tao (Journal article, 2023)This paper is devoted to investigate the robust duality and saddle point characterizations of nonconvex multiobjective optimization with data uncertainty in both the objective and constraints. Based on the robust necessary ... -
ZnO-Carbon-Nanotube Composite Supported Nickel Catalysts for Selective Conversion of Cellulose into Vicinal Diols
Van der Wijst, Cornelis; Duan, Xuezhi; Liland, Ingvild Skeie; Walmsley, John; Zhu, Jun; Wang, Aiqin; Zhang, Tao; Chen, De (Journal article; Peer reviewed, 2015)A ZnO-nanolayer-coated carbon nanotube (CNT) composite (ZnO–CNT) was employed as a support to immobilise Ni catalysts. Well-mixed oxides, formed as a result of enhanced interfaces between the two oxides on CNTs, resulted ...
