Synchronization and fault tolerance of processes are emphasis in the distributed systems research, but only a few people involves in the mathematics model used in processes synchronization and fault tolerance yet. This paper takes distributed system as an event driven system, classify the events that cause system state variety into four classes, and proposed an extended finite state machine (EFSM)...
In the algorithms of setting checkpoint intervals, it is significant to minimize the time and space overhead for enhancing computational efficiency. Under the existence of dynamic checkpoint intervals, a novel dynamic checkpoint intervals algorithm, named MDCI, based on hidden semi-Markov model has been proposed, which adopts random time series analysis method. The method not only decreases the computing...
Five short tandem repeat (STR) systems of TH01, vWA, LPL, F13B and FES/FPS were investigated in five ethnic groups living in China (Tujia, Miao, Bai, Chaoxian and Han). All five loci did not deviate from the Hardy-Weinberg equilibrium (P>0.05). At the five loci of each ethnic group, the observed heterozygosity, the mean exclusion chance (MEC), and the power of discrimination (PD) ranged from 0...
