    High performance full diversity LDPC codes construction and performance analysis for H-ARQ channels by Rui GUO, Fang-ning HU, Ji-lin LIU

    Published 2012-04-01
    “…In order to improve the performance of communication system with hybrid automatic repeat request(H-ARQ),a kind of full diversity low density parity check(LDPC)codes on H-ARQ block-fading channels was proposed.First,the outage probability and inherent diversity were analyzed,then a kind of full diversity PDPC codes for H-ARQ channel was designed.The new proposed LDPC codes connected the initial transmission with the repeated transmissions by root-connection to get extern diversity gain.In addition,the relationship between the structure of full diversity LDPC codes and the coding gain was given,and an algorithm to improve coding gain was brought forward by increasing the proportion of full diversity parity bits.Simulation results show that the proposed algorithm can not only achieve full diversity,but also get better performance than constructed LDPC codes at present.…”

    Les représentations de l’eau by Bernadette De Vanssay

    Published 2008-07-01
    “…(Osaka, Brasilkia, Djakarta, Munich, Madrid and Ouagadougou). From the results of the french surveys, common elements of the representations were drawn up and used to build a general scheme of the representations ; then they permit to define some profiles of attitude towards water resources.Results of the other towns studies demonstrated the impact of cultural backgrounds upon representations, the major dimensions orientating the representations and the triggers usable in each culture to modify or reinforce public behaviours related to water. …”

    Thermal Analysis and Rigid-Flexible Coupling Dynamics of a Satellite with Membrane Antenna by Xiang Liu, Guoping Cai

    Published 2022-01-01
    “…Considering the thermal stress, the vibration modes of the membrane antenna structure are obtained, and the rigid-flexible coupling dynamic model of the membrane-antenna-satellite system is derived based on the hybrid coordinate method. To reduce the vibration of the membrane antenna structure caused by the attitude maneuver, the control command is designed based on the component synthesis vibration suppression (CSVS) method. …”

    Les revenants et leurs liens avec les êtres et les objets « transitionnels » by María Dolores Muñoz Jiménez

    Published 2016-06-01
    “…In the links between the two worlds living entities acquire ambivalent functions, carrying also a double identity living and dead (or living in contact with the dead and contaminated by that). That makes them hybrid entities that I have named transitional (because they are symbolically between the two worlds). …”

    Research on security architecture of strong PUF by adversarial learning by Yan LI, Wei LIU, Yuanlu SUN

    Published 2021-06-01
    “…To overcome the vulnerability of strong physical unclonable function, the adversarial learning model of strong PUF was presented based on the adversarial learning theory, then the training process of gradient descent algorithm was analyzed under the framework of the model, the potential relationship between the delay vector weight and the prediction accuracy was clarified, and an adversarial sample generation strategy was designed based on the delay vector weight.Compared with traditional strategies, the prediction accuracy of logistic regression under new strategy was reduced by 5.4% ~ 9.5%, down to 51.4%.The physical structure with low overhead was designed corresponding to the new strategy, which then strengthened by symmetrical design and complex strategy to form a new PUF architecture called ALPUF.ALPUF not only decrease the prediction accuracy of machine learning to the level of random prediction, but also resist hybrid attack and brute force attack.Compared with other PUF security structures, ALPUF has advantages in overhead and security.…”
