    Research on Basic Theory and Key Technology of Cognitive Radio Network by Ping Zhang, Jianwu Li, Zhiyong Feng, Qixun Zhang

    Published 2014-02-01
    “…Cognitive radio network(CRN)is a cognitive process of network,which makes planning,decision and response for network state through learning and analysis of the network environment.CRN is one of the effective ways to solve the limited network capacity,and to satisfy the national strategic demand on the frequency spectrum efficient-utilization and the integration of heterogeneous networks.As the key technology of 5G,CRN indicates the direction for the future development of wireless communication network.The system architecture for cognitive radio networks,the basic theory research,the key technologies of implementation were introduced,and the demonstration platform of CRN was presented.…”

    APPLICATION OF HARMONIC FUNCTION’S THEORY IN TWO-DIMENSION OPTIMIZATION PROBLEM by ZHANG Jing, SHI WenPu

    Published 2018-01-01
    “…The mathematical models of many engineering problems can often come down to two-dimensional optimization problems,it has been one of the hot issues of seeking the high effective and precision optimizing method.The characteristics of harmonic function and Green theory were used to study the relations between the values of harmonic function and its boundary values,and demonstrate the non-locality of its extreme value.When the objective function of the optimization is harmonic function,the two-dimensional optimization can be simplified as a one-dimensional optimization on the boundary of its feasible region.At last,three examples were given to show the feasibility of the method here.The research ideas and the conclusions can be generalized to the solution of the three-dimensional optimization problems.…”

    Quantum dynamics of the effective field theory of the Calogero-Sutherland model by Federico L. Bottesi, Guillermo R. Zemba

    Published 2025-03-01
    “…We consider the known effective field theory of the Calogero-Sutherland model in the thermodynamic limit of large number of particles, obtained from the standard procedure in conformal field theory: the Hilbert space is constructed a priori in terms of irreducible representations of the symmetry algebra, and not by diagonalization of the hamiltonian, which is given in terms of fields that carry representations of the W1+∞ algebra (representing the incompressibility of the Fermi sea). …”
