    The minimum matching energy of unicyclic graphs with fixed number of vertices of degree two by Bai Yongqiang, Ma Hongping, Zhang Xia

    Published 2024-12-01
    “…In this article, by utilizing several new graph transformations, we determine the least element with respect to the quasi-order ≽\succcurlyeq among all unicyclic graphs with fixed order and number of vertices of degree two. As consequences, we characterize the graphs with minimum matching energy and with minimum Hosoya index in the set of all unicyclic graphs with fixed order and number of vertices of degree two.…”

    Access control oriented quantified trust degree representation model for distributed systems by LANG Bo

    Published 2010-01-01
    “…Based on the research fruit of social trust in sociology,the semantics,properties and elements of trust in the context of access control of distributed systems were defined.By combining fuzzy set theory with probability theory,a mathematical definition of trust was given,a quantified trust degree representation model including an integrated trust evaluation model and a trust calculating algorithm was established.The model integrates multiple elements of trust,and is in accordance with the decreasing and enhancing rules of the recommended trust.…”
