Gossip-based Wireless Sensor Networks (GWSN) are complex systems of inherently random nature. Planning and designing GWSN requires a fast and adequately accurate mechanism to estimate system performance. As a first contribution, we propose a performance analysis technique that simulates the gossip-based propagation of each single piece of data in isolation. This technique applies to GWSN in whi...

This paper studies for the first time effect of spatial variability ground motions (SVGM) with large intensities on inelastic seismic response pylons which are responsible overall structural integrity cable-stayed bridges. The svgm is defined by delay earthquake at different supports, loss coherency waves and incidence angle motion. An extensive study conducted bridges ‘H’- inverted ‘Y’-shaped ...

The spatial variation of ground motion (SVGM) can significantly affect the response distributed infrastructure systems including bridges, dams, and pipelines. SVGM-related phenomena are result combination three effects: (1) wave passage, (2) geometric incoherence input, (3) ground- site-effects due to soil layering, presence topographic irregularities, and/or alluvial basins. Existing models ab...

Besides phase variability, amplitude variability is one of the two manifestations spatially varying ground motion (SVGM) in frequency domain. Neglecting earthquake spectra can result an underestimation structural responses. Few existing models be used for estimating at a distance from reference location. In this paper, new model describing evolution energy developed based on records five events...

Abstract Premise Microclimatic differences between the periphery and interior of tree crowns result in a variety adaptive leaf macromorphological anatomical features. Our research was designed to reveal criteria for sun/shade identification two species evergreen oaks, applicable both modern fossil leaves. We compared our results with those other similarly studied. Methods For Quercus bambusifol...

Long-span bridges, as vital structures, play a very important role in economic development. Furthermore, the results of several earthquake-damaged bridges showed that their seismic behavior was different from that predicted under uniform excitation and in some cases the responses were more than predicted results. Therefore, the damaged bridges under non-uniform excitations were re-analyzed and ...
