Experimental Studies on Particle Emissions from Grate Fired Biomass Combustion Boilers

Fine particle emissions were measured at two commercial grate fired boilers operating on moist fuel residues. The aim of this study was to characterize fine particle emissions with a view to pinpoint parameters influencing the emissions. Additionally effectiveness of used flue gas cleaning techniques was assessed. The results show that large quantities of fine particles are emitted to the atmosphe

Statistical MIMO Propagation Channel Models - An overview

Statistical propagation channel models for MIMO systems can be grouped into two classes: physical and analytical. Physical models describe the statistics of the multipath components and are in widespread use for implementation and testing of systems (e.g. 3GPP, IEEE 802.11n). Analytical (or nonphysical) models describe the statistics of the transfer functions between the antenna elements at the tr
