A unit testing approach for AspectJ programs is proposed to separately test aspect units which have their own states. In the approach, aspects under test are co
A nonautonomous predator-prey difference model with Beddington-DeAngelis functional response,diffusion,and time delays is investigated. The model consists of n
Particle swarm optimization (PSO) was modified by variation method of particle velocity, and a variation PSO (VPSO) algorithm was proposed to overcome the short
Using the decomposition technique of equation and the fixed point theorem,the existence of solution and positive solution is studied for a nonlinear cantilever
To explore the potential capacity of dual-right-turn lanes at signalized intersections under mixed traffic conditions,we defined two conflict zones between righ
