    Towards object-based image editing by Zhou, Hailing

    Published 2012
    “…In particular, to overcome the lack of effectiveness and accuracy in extracting objects from complex backgrounds (especially with textures or low contrasts), we propose to incorporate image texture information into energy functions in graph-based image segmentation, use structure tensors to modify the weight between two nodes in the image graph, adopt a constrained active contour model to handle region and boundary simultaneously, and design a ``soft" brush interface for users to locally adjust segmentation results. …”

    Some rigidity results for the Hawking mass and a lower bound for the Bartnik capacity by Mondino, A, Templeton-Browne, A

    Published 2022
    “…We infer a small yet explicit and strictly positive lower bound on the Bartnik mass of open sets (non-locally isometric to Euclidean $\mathbb {R}^{3}$ ) in terms of curvature tensors. Inspired by these results, in the appendix we propose a notion of ‘sup-Hawking mass’ which satisfies some natural properties of a quasi-local mass. …”

    A Decomposition Method for Global Evaluation of Shannon Entropy and Local Estimations of Algorithmic Complexity by Hector Zenil, Santiago Hernández-Orozco, Narsis A. Kiani, Fernando Soler-Toscano, Antonio Rueda-Toicen, Jesper Tegnér

    Published 2018-08-01
    “…The measure may be adapted for use with more multi-dimensional objects than strings, objects such as arrays and tensors. To test the measure we demonstrate the power of CTM on low algorithmic-randomness objects that are assigned maximal entropy (e.g., &pi; ) but whose numerical approximations are closer to the theoretical low algorithmic-randomness expectation. …”

    Effectiveness of embedded discontinuities technique in capturing geomechanical behavior in naturally fractured reservoirs by Bruno Maciel, Leidy Laura Alvarez, Nayara Torres Belfort, Leonardo José do Nascimento Guimarães, Leila Brunet de Sá Beserra

    Published 2023-12-01
    “…To analyze this behavior, numerical simulation results using the proposed method were compared, under different liquid pressure depletion values, with the approach proposed by Oda, which is commonly used in commercial software for calculating fracture permeability tensors. This approach was enriched with Barton's fracture closure formulation and updates on rock matrix porosity and permeability. …”

    Flow in an hourglass: particle friction and stiffness matter by Tivadar Pongó, Viktória Stiga, János Török, Sára Lévay, Balázs Szabó, Ralf Stannarius, Raúl Cruz Hidalgo, Tamás Börzsönyi

    Published 2021-01-01
    “…Using DEM data combined with a coarse-graining methodology allows us to compute all the relevant macroscopic fields, namely, linear momentum, density and stress tensors. The observed difference in the discharge in the low friction limit is connected to a strong difference in the pressure field: while for hard grains Janssen-screening is effective, leading to high vertical stress near the silo wall and small pressure above the orifice region, for deformable grains the pressure above the orifice is larger and gradually decreases during the discharge process. …”
