Pre- to Post-discharge Behavior in Saline Solution

The development of a plasma discharge at low voltage (200-600 V) in saline solution is characterized using fast and standard CCD camera imaging. Vapor formation, plasma formation, and vapor collapse and subsequent pressure wave propagation are observed. If, with increasing voltage, the total energy deposited is kept approximately constant, the sequence and nature of events are similar but develop faster and more reproducibly at the higher voltages. This is attributed to the slower temporal evolution of the vapor layer at lower voltages which means a greater sensitivity to hydrodynamic instabilities at the vapor-liquid interface.

A hardware solution on multi-field packet classification

In this paper, a hardware solution for packet classification based on multi-fields is presented. The proposed scheme focuses on a new architecture based on the decomposition method. A hash circuit is used in order to reduce the memory space required for the Recursive Flow Classification (RFC) algorithm. The implementation results show that the proposed architecture achieves significant performance advantage that is comparable to that of some well-known algorithms. The solution is based on Altera Stratix III FPGA technology.
