This paper concentrates on analyzing the stability problems of aperiodic sampled-data systems with time delay.Based on Lyapunov theory, a new time-square-dependent two-side looped-functional (TTLF) is proposed, which can take full advantage of the second order terms with respect to time.And by using the intrinsic Bowl relationships of state vectors
The failure mode and breaching time of a natural dam are affected by many factors.To comprehensively analyse the effects of these factors on dam failure modes, 159 runs of laboratory experiments were Remote Control performed with 11 channel bed slopes, 4 dam geometric shapes, 3 construction materials, and 8 inflow rates.Through these experiments, t
