    A Repeatable Optimization for Kinematic Energy System with Its Mobile Manipulator Application.Ying Kong, Ruiyang Zhang, Yunliang Jiang & Xiaoyun Xia - 2019 - Complexity 2019:1-16.
    For repeatable motion of redundant mobile manipulators, the flexible base platform and the redundant manipulator have to be returned to the desired initial position simultaneously after completing the given tasks. To remedy deviations between initial position and desired position of each kinematic joint angle, a special kind of repeatable optimization for kinematic energy minimization based on terminal-time Zhang neural network with finite-time convergence is proposed for inverse kinematics of mobile manipulators. It takes the advantages that each joint of the manipulator (...)

    Stress Perturbations Around the Deep Salt Structure of Kuqa Depression in the Tarim Basin.Mingwen Wang, Yunqiang Sun, Gang Luo, Rui Zhang & Cheng Chang - 2019 - Interpretation 7 (3):T647-T656.
    Drilling into and around salt bodies can present different kinds of geohazards, such as shrinkage or stuck and crushed casings, resulting in well abandonment and huge economic losses. These engineering disasters are more likely to happen when ignoring the stress perturbations caused by the geomechanical interactions between the salt and surrounding sediments. For a better understanding of the stress perturbations, we use a commercial finite-element software, Abaqus, to build a 2D plane-strain finite-element model of the salt structure of Kuqa depression (...)

    Machine Learning for Geophysical Characterization of Brittleness: Tuscaloosa Marine Shale Case Study.Mark Mlella, Ming Ma, Rui Zhang & Mehdi Mokhtari - 2020 - Interpretation 8 (3):T589-T597.
    Brittleness is one of the most important reservoir properties for unconventional reservoir exploration and production. Better knowledge about the brittleness distribution can help to optimize the hydraulic fracturing operation and lower costs. However, there are very few reliable and effective physical models to predict the spatial distribution of brittleness. We have developed a machine learning-based method to predict subsurface brittleness by using multidiscipline data sets, such as seismic attributes, rock physics, and petrophysics information, which allows us to implement the prediction (...)

    Fractures and fracture-related dissolution pores, as well as cavities, molds, and vugs, provide the major conduit and/or storage space for hydrocarbons in the deeply buried carbonate hill of Hexiwu field, Bohai Bay Basin. The fractured reservoir generally has lower porosity but better permeability than moldic/vuggy reservoir, and it consists of the major part of the buried-hill slope and buried-hill internal reservoirs. The conventional method of characterizing carbonate reservoirs, however, often mixes these two types of reservoirs together because they both have (...)

    Creating Detailed Subsurface Models Using Predictive Image-Guided Well-Log Interpolation.Parvaneh Karimi, Sergey Fomel & Rui Zhang - 2017 - Interpretation: SEG 5 (3):T279-T285.
    Integration of well-log data and seismic data to predict rock properties is an essential but challenging task in reservoir characterization. The standard methods commonly used to create subsurface model do not fully honor the importance of seismic reflectors and detailed structural information in guiding the spatial distribution of rock properties in the presence of complex structures, which can make these methods inaccurate. To overcome initial model accuracy limitations in structurally complex regimes, we have developed a method that uses the seismic (...)

  8. Perceived Social Support and Life Satisfaction in Infertile Women Undergoing Treatment: A Moderated Mediation Model.Xiying Chu, Yaoguo Geng, Ruiping Zhang & Wenjing Guo - 2021 - Frontiers in Psychology 12.
    Perceived social support is positively related to life satisfaction in infertile women. Whereas, the underlying mechanism of this relationship is unclear. The present study aimed to investigate whether self-compassion mediated the relationship of perceived social support with life satisfaction and whether infertility self-efficacy moderated the relationship between perceived social support and self-compassion in infertile women. A total of 290 infertile women in mainland China undergoing treatment completed an online survey assessing perceived social support, life satisfaction, self-compassion, and infertility self-efficacy. The (...)

    An Exponential Varying-Parameter Neural Network for Repetitive Tracking of Mobile Manipulators.Ying Kong, Qingqing Tang, Jingsheng Lei & Ruiyang Zhang - 2020 - Complexity 2020:1-12.
    A novel exponential varying-parameter neural network is presented and investigated to solve the inverse redundancy scheme of the mobile manipulators via quadratic programming. To suspend the phenomenon of drifting free joints and guarantee high convergent precision of the end effector, the EVPNN model is applied to trajectory planning of mobile manipulators. Firstly, the repetitive motion scheme for mobile manipulators is formulated into a QP index. Secondly, the QP index is transformed into a time-varying matrix equation. Finally, the proposed EVPNN method (...)

  12. Prestack Seismic Inversion with Structural Constraints.Dong Li, Suping Peng, rui Zhang, Yinling Guo, Yongxu Lu & Xiaoqin Cui - forthcoming - Interpretation:1-41.
    Pre-stack seismic inversion usually suffers from the lower signal-to-noise ratio, which could result in unstable inversion results. The conventional multi-trace lateral constrained inversion blurs the steeply dipping layers, whereas the simple structural constrained inversion is affected by noise. To solve this issue, an inversion method with multiple constraints is proposed, which include 1) A local smoothing operator is used to suppress the inversion anomalies caused by data noise, 2) a difference operator is used to protect the stratum boundary, 3) a (...)

    It has been recognized that stress perturbations in sediments induced by salt bodies can cause elastic-wave velocity changes and seismic anisotropy through changing their elastic parameters, thus leading to difficulties in salt imaging. To investigate seismic velocity changes and seismic anisotropy by near-salt stress perturbations and their impacts on salt imaging, taking the Kuqa depression as an example, we have applied a 2D plane-strain static geomechanical finite-element model to simulate stress perturbations and calculate the associated seismic velocity changes and seismic (...)

    The In Salah carbon dioxide storage project in Algeria has injected more than 3 million tons of carbon dioxide into a water-filled tight-sand formation. During injection, interferometric synthetic aperture radar reveals a double-lobed pattern of up to a 20-mm surface uplift above the horizontal leg of an injection well. Interpretation of 3D seismic data reveals the presence of a subtle linear push-down feature located along the InSAR determined surface depression between the two lobes, which we interpreted to have to be (...)

We analyzed four meandering-braided fluvial successions from the Dongying Formation in the Wen’an Slope. The results indicate that the fluvial systems are dominantly northeast–southwest and consist of channel, channel bar, and flood plain subfacies, which can be further subdivided into six microfacies including braided channel, meandering channel, sandy channel bar, muddy channel (...)

    Depth-Domain Seismic Reflectivity Inversion with Compressed Sensing Technique.Rui Zhang, Kui Zhang & Jude E. Alekhue - 2017 - Interpretation: SEG 5 (1):T1-T9.
    More and more seismic surveys produce 3D seismic images in the depth domain by using prestack depth migration methods, which can present a direct subsurface structure in the depth domain rather than in the time domain. This leads to the increasing need for applications of seismic inversion on the depth-imaged seismic data for reservoir characterization. To address this issue, we have developed a depth-domain seismic inversion method by using the compressed sensing technique with output of reflectivity and band-limited impedance without (...)

    Time-Variant Wavelet Extraction with a Local-Attribute-Based Time-Frequency Decomposition for Seismic Inversion.Rui Zhang & Sergey Fomel - 2017 - Interpretation: SEG 5 (1):SC9-SC16.
    Seismic impedance inversion has been widely used to estimate subsurface properties. Conventional inversion assumes that seismic data are the convolution result of seismic wavelet and reflectivity, implying that seismic data are stationary when a constant wavelet is considered. However, seismic data are nonstationary because of noise contamination and attenuation during wave propagation, which means that the frequency spectrum of the seismic signal changes from shallow to deep formations. We have developed a time-variant wavelet extraction method by using a local-attribute-based spectral (...)
