    First General Zagreb Index of Generalized F-sum Graphs by H. M. Awais, Muhammad Javaid, Akbar Ali

    Published 2020-01-01
    “…The first general Zagreb (FGZ) index (also known as the general zeroth-order Randić index) of a graph G can be defined as MγG=∑uv∈EGdGγ−1u+dGγ−1v, where γ is a real number. As MγG is equal to the order and size of G when γ=0 and γ=1, respectively, γ is usually assumed to be different from 0 to 1. …”

    Scrambler blind recognition method based on soft information by Ze-liang CHEN, Hua PENG, Ke-xian GONG, Pei-dong YU

    Published 2017-03-01
    “…Two scrambler blind recognition methods based on soft information were proposed for received signal in non-cooperative ways.The first method established a cost function of the scrambler coefficients by using the soft information,and adopted the optimization theory of real number field for positive solution.So it didn’t need to traverse the closed set of test polynomial any more.The second method built conformity degree concept with the soft information,and used the size of conformity of each test scrambler polynomial as the discriminant criteria.So it made more full use of the received information compared to the hard sentence recognition algorithm.Simulation results show that the first method can shorten the recognition time of a synchronous scrambler polynomial from 5 min 18 s to 8 s compared with the traversal method put forward by Cluzeau,and the second method has 2 dB SNR gain when to achieve the relatively high accuracy compared with the hard sentence recognition algorithm.…”

    Privacy preserving based on differential privacy for weighted social networks by Li-hui LAN, Shi-guang JU

    Published 2015-09-01
    “…Focusing on the weak protection problems in privacy preservation of weighted social networks publication,a privacy preserving method based on differential privacy was put forward for strong protection of edges and edge weights.The WSQuery query model was proposed meeting with differential privacy on weighted social networks,could capture the structure of weighted social networks and returned the triple sequences as the query result set.The WSPA algorithm was designed according to the WSQuery model,could map the query result set into a real number vector and injected Laplace noise into the vector to realize privacy protection.The LWSPA algorithm was put forward because of the high error of the WSPA algorithm,partitioned the triples sequence of the query results into multiple subsequences,constructed the algorithms for each subsequence according with differential privacy and reduced the error and improved the data util-ity.The experimental results demonstrate that the proposed method can provide strong protection for privacy information,simultaneously the utility of the released weighted social networks is still acceptable.…”

    Published 2012-01-01
    “…Emotional cellular (EC), proposed in our previous works, is a kind of semantic cell that contains kernel and shell and the kernel is formalized by a triple- L = <P, d, δ>, where P denotes a typical set of positive examples relative to word-L, d is a pseudodistance measure on emotional two-dimensional space: valence-arousal, and δ is a probability density function on positive real number field. The basic idea of EC model is to assume that the neighborhood radius of each semantic concept is uncertain, and this uncertainty will be measured by one-dimensional density function δ. …”
