Abstract: Systems and methods are disclosed for enhancing uplink throughput at a small cell base station. The small cell base station may monitor a power level associated with one or more user device (UD) transmissions from a UD, determine that the UD is at a UD transmit power floor based on the monitored power level, and adjust a data rate assigned to the UD based on the determination that the UD is at the UD transmit power floor.

Abstract: A rotatable assembly for use with a gas turbine engine comprises a rotatable disk, and a plurality of blades for affecting a flow of air passing thereover during use. The blades are attached to the rotatable disk, and each one of the plurality of blades has a blade root and a blade tip disposed opposite said blade root. A first ring self supporting is disposed adjacent a first portion of each of the blade tips, the first ring being in interfering contact with the first portion of each blade tip when the rotatable disk is stationary. The interfering contact is preferably between about 0.01 inches and about 0.1 inches. The first ring can be provided over a portion of the blade tips or can extend from about the leading edge of each blade to about its trailing edge. A second ring in interfering contact with the blade tips can also be provided.
