An OJ system is an online system to test programs in programming contests automatically. Performance enhancement of OJ systems in SMP environment is described in this paper. First, we introduce the affinity algorithm to improve the precision of the user programs' processing time. Second, by using queuing theory, a theoretical analysis and improvement of the(More)
With the improvement of target maneuvering performance, noises statistical character changes correspondingly in the opto-electronic tracking system. To solve this problem, robust extend Kalman filter (REKF) based on the acceleration non-zero mean value time-correlation model was given in this paper. Result of the simulation shows that, comparing with extend(More)
