After reviewing briefly the basic strategy of analyzing the RHIC data, recent lattice results of the non-pertubative/strong-coupling aspects of quark-gluon plasma probed primarily by the heavy quarks are presented. In particular, free energies of static quarks in various color channels, the Debye screening mass and the spatial string tension above the pseudo-critical temperature are discussed o...

Wired Equivalent Privacy (WEP) is an IEEE 802.11 standard implemented to provide security to data transmitted on wireless networks. In this paper we enhance the WEP security by improving the authenticity, integrity and confidentiality mechanisms. WEP uses static 40 bit as pre-shared secret key for pseudo noise sequence generation. Our method uses dynamic key which keeps changing time to time de...

Abstract Rockfill dams with stone pitching are specific hydraulic structures generally built in the early XXth century where stones used to be hand‐placed without mortar constitute upward and downward dam faces. Few studies have been carried out quantify critical role of stability against both static seismic forces. Herein, a numerical model is proposed pseudo‐static tests performed on four dif...
