Given a parallel or distributed system, the interconnection network ensures the communication between the processors, the terminal nodes. Each intermediate node has a router, a dedicated co-processor which forwards the messages between processors through the links of the underlying topology. The routers run a distributed algorithm which specifies the way to go from a node of the network to anot...

evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...

This study presents the integrated control/structure design of a large flexible structure, the Extra Long Mast Observatory (ELMO). The integrated design is performed using structuredH∞ control tools, developing the Two-Input Two-Output Port (TITOP) model of the flexible multi-body structure and imposing integrated design specifications as H∞ constraints. The integrated control/structure design ...

Dynamic reconfigurations are a powerful approach for the adaption of component-based or service-oriented software systems at runtime. Important issues in this area are the problems of state transfer and state consistency, i.e., to determine the system state after a reconfiguration and to ensure that it is valid. To deal with these problems, we introduce distributed port automata in this paper. ...

Abstract—A broadband dual-feed dual-polarized microstrip antenna with low cross polarization and high isolation is presented. The dualorthogonal linearly polarized mode is excited by two different feed mechanisms from a single circular radiating patch. One of the two modes is excited by a pair of L-shaped probes with a 180◦ phase differences, and the other is excited by an H-shaped aperture. Th...

This article studies the telegrapher’s equations with boundary port variables. Firstly, a link is made between the telegrapher’s equations and a skewsymmetric linear operator on a spatial domain. Associated to this linear operator is a Dirac structure which includes the port variables on the boundary of this spatial domain. Secondly, we present all partitions of the port variables into inputs a...
