A method and system for collecting test and measurement data for a wireless communication system utilizes a network overlay geo-location system to collect the data. Then, when an interrupt signal for converting images is inputted during one of a plurality of driving intervals, a charge of the electrophoretic particles is compensated, which is charged in correspondence with the -th image displayed on the EPD panel before the interrupt signal is inputted, and then a -th image is displayed on the EPD panel. A therapeutic composition for treating and preventing cellular metabolic injury, preventing cardiac cell damage, and increasing heat shock protein expression where in the therapeutic includes a single dose of glutamine in a pharmaceutically acceptable carrier is also provided. The switch port randomly discards incoming cells assigned to the flow queue with a probability that increases with the incoming cells’ assigned weights.
