Seasonal forecasts of the summer 2016 Yangtze River basin rainfall
Philip E. Bett, Adam A. Scaife, Chaofan Li +8
The Yangtze River has been subject to heavy flooding throughout history, and in recent times severe floods such as those in 1998 have resulted in heavy loss of life and livelihoods…
The reliable solution and computation time of variable parameters Logistic model
Wang Pengfei, Pan Xinnong
The reliable computation time (RCT, marked as Tc) when applying a double precision computation of a variable parameters logistic map (VPLM) is studied. First, using the method prop…
Forward period analysis and the long term simulation of a periodic Hamiltonian system
Pengfei Wang
The period of a Morse oscillator and mathematical pendulum system are obtained, accurate to 100 significant digits, by forward period analysis (FPA). From these results, the long-t…
On the relation between reliable computation time, float-point precision and the Lyapunov exponent in chaotic systems
PengFei Wang, JianPing Li
The relation among reliable computation time, Tc, float-point precision, K, and the Lyapunov exponent, λ, is obtained as Tc= (lnB/λ)K+C, where B is the base of the float-point syst…
On the linear operation of cloned dynamical systems and its Lyapunov exponents
Pengfei Wang
The cloned dynamical system theory is introduced and the Lyapunov exponents of this system are qualitatively proven to be same as the original dynamical system. This property indic…
