Multicast is an internetwork group communication service which reduces the transmission overheads. The data can be secured by encrypting it with a group key, shared among all group members [6]. Whenever members join/leave in a group communication, it is essential to preserve the forward and backward confidentiality by sending new keys for transmission. When members join/leave frequently, it giv...

Semi-rigid design represents, by its intrinsic nature, a new option aimed at improving the competitiveness of steel construction. This objective can be achieved via Knowledge-Based approaches. In the perspective of design automation, our research proposes a novel methodology for the detailed analysis of a braced building frame adopting semi-rigid steel joints. A software tool was developed in o...

Abstract Limited by rigid instruments, traditional open curettage of bone cysts requires large incisions and the removal substantial amounts healthy tissue to approach lesion. This causes a lengthy recovery period with an increased risk for complications. While other less invasive methods have been suggested, none accepted as standard treatment modalities, many them not applied beyond academic ...

This article studies the multiagent control problem for affine, rigid, and translational formation, with aim of developing a unified distributed strategy global finite-time convergence. Global stabilization rigid formation in arbitrary dimensional spaces still remains open challenging. provides general solution to this based on sliding mode idea. The law design consists two parts: main force re...
