    The Thermal Effect on the Physical Properties and Corresponding Permeability Evolution of the Heat-Treated Sandstones by Xianshan Liu, Weiluo Lu, Man Li, Nandou Zeng, Tao Li

    Published 2020-01-01
    “…Furthermore, the relationship between the permeability and the crack volumetric strain of the heat-treated sandstones is further analyzed to prove the mechanism of the permeability evolution. In addition, a damage model has been proposed to deeply determine the correlation of the permeability and damage variables, indicating that gradual damage variation has caused obvious cracks to form flow paths and abruptly change the permeability variation, revealing that the damage can describe the permeability evolution of the heat-treated sandstones considering different temperature and loading conditions.…”

    Optical Access Network Evolution Trends:Software Defined Optical Access Network by Rentao Gu

    Published 2015-10-01
    “…The rapid growth of new services and emerging network scenarios has serious impact on the existing network infrastructure,and it is an inevitable trend to build a new,high-speed and efficient access network architecture.The challenges faced by the existing network were analyzed,and it was pointed out that high-speed broadband access,efficient resource utilization,support for heterogeneous resource control would be future trends in the evolution of optical access networks.Then the access network development was recalled,the overall architecture of software-defined optical access network was described,SDN idea and OLT pooling technology were introduced into optical access network,and the major key technologies were analyzed,including the flexible programmable optical layer techniques,fine flow table forwarding,control layer virtualization,and etc.Several typical application scenarios suitable for software-defined optical access network were also presented.All of these indicate that the research and development on software-defined optical access network will meet current challenges and ultimately be helpful to achieve the end-to-end flexible control in the entire network.…”

    Infinite Horizon Optimal Control of Stochastic Delay Evolution Equations in Hilbert Spaces by Xueping Zhu, Jianjun Zhou

    Published 2013-01-01
    “…The aim of the present paper is to study an infinite horizon optimal control problem in which the controlled state dynamics is governed by a stochastic delay evolution equation in Hilbert spaces. The existence and uniqueness of the optimal control are obtained by means of associated infinite horizon backward stochastic differential equations without assuming the Gâteaux differentiability of the drift coefficient and the diffusion coefficient. …”
