The problem of user scheduling with reduced overhead of channel estimation in the uplink of Massive multipleinput multiple-output (MIMO) systems has been considered. A geometry-based stochastic channel model (GSCM), called the COST 2100 channel model has been used for realistic analysis of channels. In this paper, we propose a new user selection algorithm based on knowledge of the geometry of t...

Channel geometry combined with surface chemistry enables a stable liquid boundary flow to be attained along the surfaces of a 12 microm diameter hydrophilic glass fiber in a closed semi-elliptical channel. Surface free energies and triangular corners formed by PDMS/glass fiber or OTS/glass fiber surfaces are shown to be responsible for the experimentally observed wetting phenomena and formation...

Understanding the flow fields at the micro-scale is a key to develop methods of successfully mixing fluids for micro-scale applications. This paper investigates flow characteristics and mixing of three different geometries in micro-channel. A Circular groove micro mixer has been designed and simulated. One such channel is shown in Figure1. The geometry of the channels taken was rectangular with...

1. introduction floods are among earth's most common and most destructive natural hazards. floods create geomorphic hazards via changes in sediment transport and channel configuration (e.g. channel width, lateral migration, planform changes, etc). in this context, floodplain zoning and its application in spatial planning is important in non- structural measures in order to reducing flood damage...

A vortex molecule is a topological excitation in two coherently coupled superfluids consisting of each superfluid connected by domain wall the relative phase, also known as Josephson vortex. We investigate dynamics this quasi-two-dimensional geometry with slab or channel boundary conditions using an extended point-vortex framework complemented Gross-Pitaevskii simulations. Apart from translatio...
