Design and simulation of a tunable frequency OTA -C Chebyshev filter by JIANG Jin-guang, WANG Yao-nan

“…A new transconductor operational amplifier（OTA） using active resistor of source degeneration was presented.The method was developed through acting differential pair degenerated by two MOSFET operating in the triode region as active resistor in its input stage,the circuit was designed in working in stable quiescent operating point with folded cas-cade output stage using voltage common-mode feedback（CMFB） circuit.As an tunable cutoff frequency fourth order Chebyshev lowpass filter,an accurately tunable Gm of OTA was used,which employed switching capacitor technique to tune Gm value.Simulated results show that the practical frequency response of the filter is very near to that of idealized prototype by applying 2-poly 4-metal 3.3V power supply 0.35μm CMOS technology spice model.…”

Abnormal network traffic detection approach based on alive entropy by Xiang-kun MU, Jin-song WANG, Yu-feng XUE, Wei HUANG

“…A novel alive entropy-based detection approach was proposed,which detects the abnormal network traffic based on the values of alive entropies.The alive entropies calculated based on the NetFlow data coming from the network traffic of input and output of a whole system,which is essentially a monitored network.In order to decrease false positive rate of abnormal network traffic,different scales are selected to compute the values of alive entropies in different sizes of network traffic.With the low false positive rate of abnormal network traffic,the abnormal network traffic can be effectively detected.Experiments carried out on a real campus network were used to evaluate the effectiveness of the proposed approach.A comparative study illustrates that the proposed approach may easily detect the abnormal network traffic with random characteristics in comparison with some “conventional” approaches reported in the literatures.…”

Géopolitique touristique d’un « bout du monde » by Nicolas Savelli

“…Dans ce « bout du monde » en situation de marge géographique et économique, le choix de baser le développement territorial sur un ré-ancrage autour de la haute montagne a été effectué. Faire un « pas de côté » et travailler en réseau au sein de la filière doit permettre à un « outsider » de trouver sa place sur le marché touristique L’autarcie géographique, identifiée comme un handicap à l’origine semble au contraire être un générateur d’innovation par l’intelligence collective grâce aux marges d’actions que possède le territoire.…”

Design of precoding matrices in MIMO full duplex two-way security communication system by Weijia LEI, Yang ZHOU, Xianzhong XIE, Hongjiang LEI

“…The design of precoding matrices was studied in the multiple input multiple output (MIMO) full-duplex two-way security communication system where legitimate nodes transmit the confidential information accompanied by the artificial noise while receiving information.For the scenario where the perfect channel state information (CSI) of legitimate channels and eavesdropping channels was available,the difference of concave/convex (DC) programming was used to optimize the precoding matrices of the information signal and the artificial noise for the maximization of the secrecy sum rate.For the scenario where the CSI was imperfect,the channels were modeled by using worst-case criterion and the weighted minimum mean square error algorithm was used to get the robust precoding matrices of the information signal and the artificial noise.The simulation results prove that the proposed algorithm can effectively promote the secrecy sum rate of the system.…”

25 Gbit/s transmission performance using duo-binary detection with 10 Gbit/s-PON receiver by Yongjia YIN, Yong GUO, Zhuang MA

“…IEEE has formed the 100 Gbit/s-EPON Task Force to develop next 100 Gbit/s-PON standards，and the duo-binary(DB) detection is one of the baseband technology options.25 Gbit/s DB detection transmission performance with 10 Gbit/s-PON receiver was been experimentally demonstrated.Because the bandwidth of 10 Gbit/s- PON receiver is obviously limited,the 25 Gbit/s DB output signal from 10 Gbit/s-PON receiver will be affected by the inter-symbol interference(ISI).The experiment results show that the system receiving sensitivity based on direct decision method is only -22 dBm.However,the system receiving sensitivity can be up to -24.5 dBm by using the most simplified maximum likelihood sequence estimation(MLSE) soft decision method.…”
