A new compact ping-pong exchange design based on signal-data processing is also brought forward to implement the parallel transition between the 32 route asynchronous serial data with the E1 data stream of two million bits per second with one xilinx XCS20TQ144.

Research progress of open cell metal foams used in compact heat exchanger;

Finally it constructs an address counter and introduces the ping-pong alternative storage method to satisfy the demand of corner turn memory in real-time SAR image system.

Considering lack of comparative studies on Ping-pong handover,a comprehensive evaluation was carried out to estimate the handover performance of layer-3 of TCP protocol based on end-to-end for various Mobile IPv6 extensions.

Based on this model,this paper analyzes the impacts of the brush touching resistance on the measurement of the grounding resistance when the impressed DC voltage method,the impressed AC voltage method and the Ping-Pang switch method are adopted respectively,obtaining the fol.
