Dual-computer warm standby redundant architecture is one of the most commonly used architectures in redundant fault tolerance. Using this architecture, the computing results of the backup computer is unused when it has no power although the backup computer is keep running that is a waste of computing resource of the backup computer. This paper proposes a co-processing method which makes rational use...
A method of lightweight optimization design based on crash is developed for car body. The thicknesses of car body parts are optimized with an objective of minimized body weight and the restraint of body stiffness and modal. The crashes of car body and occupant restraint system are simulated to verify the safety performance of lightweight car body. The thicknesses of parts are modified with the result...
An algorithm named PTBBWD is presented to detect worms. It is process traffic behavior based and has considered three important behaviors: total amount of source ports in wormlike traffic, changing frequency of source ports in wormlike process traffic and the wormlike traffic proportion of the total process traffic. Unlike similar work before, PTBBWD checks the frequency and the total amount of source...
