The origins of the Federation of Digital Seismograph Networks (FDSN) can be traced to the summer of 1984.At that time, GEOSCOPE - the French global network of broadband instruments - was already well under way, and in the United States, the Incorporated Research Institutions for Seismology (IRIS) had just published its Science indefinitely baby opi
In the satellite microwave power transmission (MPT) system, antenna arrays are usually adopted for a higher gain.For the passive wideband antenna array, dc headers integra wideband power dividers are essential when the feed network is constructed.Because the microstrip-slotline coupled power divider could achieve wide bandwidth and compact size at
In this article the system of complex and elementary provocative genres is displayed.The elementary provocative genres used to engage with each other and other communication and genre phenomena in the fireface ufx iii context of indirect communication mqr93ll/a in a sort of interference which impact on their intentionality.The provocative e!ect of
Meta-heuristic algorithms have become an arising field of research in recent years.Some of these algorithms mqr93ll/a have proved to be efficient in solving combinatorial optimization problems, particularly knapsack problem.In this paper, four meta-heuristic algorithms are presented particle swarm optimization, firefly algorithm, flower pollination
