    with Shaohong Yan, Hailong Zhao, Liangxu Liu, Qiaozhi Sang, and Jie Li
    Complexity 2020 1-10. 2020.
    Coke is an indispensable and vital flue for blast furnace smelting, during which it plays a key role as a reducing agent, heat source, and support skeleton. Models of prediction of coke quality based on ANN are established to map the functional relationship between quality parameters Mt, Ad, Vdaf, St,d, and caking property of mixed coal and quality parameters Ad, St,d, coke reactivity index, and coke strength after reaction of coke. A regularized network training method based on Sigmoid function…Read more
  • Petrophysical properties difference of organic-rich and organic-poor shale reservoir using low-field nuclear magnetic resonance experiment in the Sangzhi block, South China
    with Gang Zhao, Wenlong Ding, Yaxiong Sun, Siyu Shi, Baocheng Jiao, Li Tian, Zhan Zhao, and Ning Sun
    Interpretation 8 (4). 2020.
    The petrophysical properties of rocks have an important influence on shale quality. To characterize the difference of petrophysical properties between organic-rich and organic-poor shale reservoirs, we used the low-field nuclear magnetic resonance technique and field emission scanning electron microscopy analysis after argon-ion polishing or natural section to measure porosity and permeability from six core samples from well SY6 in the Sangzhi block, Northwest Hunan province. Some information ab…Read more

    Parallel Attribute Reduction Algorithm for Complex Heterogeneous Data Using MapReduce
    with Tengfei Zhang, Fumin Ma, Jie Cao, and Dong Yue
    Complexity 2018 1-11. 2018.
    Parallel attribute reduction is one of the most important topics in current research on rough set theory. Although some parallel algorithms were well documented, most of them are still faced with some challenges for effectively dealing with the complex heterogeneous data including categorical and numerical attributes. Aiming at this problem, a novel attribute reduction algorithm based on neighborhood multigranulation rough sets was developed to process the massive heterogeneous data in the paral…Read more

  • Hidden Order and Dimensional Crossover of the Charge Density Waves in TiSe 2
    with Y. H. Chan, X. Y. Fang, S. K. Mo, Z. Hussain, A. V. Fedorov, M. Y. Chou, and T. C. Chiang
    © The Author 2016.Charge density wave formation, a key physics issue for materials, arises from interactions among electrons and phonons that can also lead to superconductivity and other competing or entangled phases. The prototypical system TiSe 2, with a particularly simple transition and no Kohn anomalies caused by electron-phonon coupling, is a fascinating but unsolved case after decades of research. Our angle-resolved photoemission measurements of the band structure as a function of tempera…Read more

    Dimensional Effects on the Charge Density Waves in Ultrathin Films of TiSe 2
    with Y. H. Chan, M. H. Wong, X. Y. Fang, M. Y. Chou, S. K. Mo, Z. Hussain, A. V. Fedorov, and T. C. Chiang
    © 2016 American Chemical Society.Charge density wave formation in solids is a critical phenomenon involving the collective reorganization of the electrons and atoms in the system into a wave structure, and it is expected to be sensitive to the geometric constraint of the system at the nanoscale. Here, we study the CDW transition in TiSe2, a quasi-two-dimensional layered material, to determine the effects of quantum confinement and changing dimensions in films ranging from a single layer to multi…Read more

    Charge density wave transition in single-layer titanium diselenide
    with Y. H. Chan, X. Y. Fang, Y. Zhang, M. Y. Chou, S. K. Mo, Z. Hussain, A. V. Fedorov, and T. C. Chiang
    © 2015 Macmillan Publishers Limited. All rights reserved.A single molecular layer of titanium diselenide is a promising material for advanced electronics beyond graphene - a strong focus of current research. Such molecular layers are at the quantum limit of device miniaturization and can show enhanced electronic effects not realizable in thick films. We show that single-layer TiSe2 exhibits a charge density wave transition at critical temperature TC =232±5 K, which is higher than the bulk TC =20…Read more
