End-users of multi-radio devices expect ubiquitous connectivity anytime and anywhere across heterogeneous networks. A minimal service disruption time while roaming across networks is key for successful deployments. Today’s roaming decisions are reactive and traditionally based on thresholds for signal strength, missed beacons, or other properties, leading to undesirable handover delays. In this...

Are democratic crises also human crises? While the determinants of erosion democracy have been extensively scrutinised in literature, their public policy consequences remain relatively unexplored. In a novel attempt to navigate this uncharted terrain, we analyse effect autocratization on health outcomes. We conceptualise as relative decline ‘vertical’ and ‘horizontal’ accountability. ‘Vertical ...

[1] We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or ...

hydraulic fracturing (hf), as a stimulation technique in petroleum engineering, has made possible the oil production from reservoirs with very low permeability. the combination of horizontal drilling and multiple hf with various perforation angles has been widely used to stimulate oil reservoirs for economical productions. despite the wide use of hf, there are still ambiguous aspects that requi...

Abstract Vertical structures exhibit flexibility than ordinary and also they show sensitivity in earthquake excitation. As per the safety standards of construction, are built with simple uniform configurations. Focusing on aesthetic view these vertical structures, discontinuity stiffness occurs there by resulting soft storey. this feature is highly undesirable buildings especially seismic activ...

From the parallaxes and proper motions of a kinematically unbiased subsample of the Hipparcos catalogue we have redetermined as a function of colour the kinematics of main-sequence stars. Whereas the radial and vertical components of the mean heliocentric velocity of stars show no trend with colour, the component in the direction of galactic rotation nicely follows the asymmetric drift relation...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-&#10Timoshenko beam elements. The ra...
