THE TRANSFORMED NONPARAMETRIC FLOOD FREQUENCY ANALYSIS

Journal of Computational Mathematics 1994年第4期12卷 330-338页

The nonparametric kernel estimation of probability density function (PDF) pro-vides a uniform and accurate estimate of flood frequency-magnitude ***, the kernel estimate has the disadvantage that the smoothing factor h is estimate empirically and is not locally adjusted, thus possibly resulting in deteri oration of density estimate when PDF is not smooth and is heavy-tailed. Such a problem can be alleviate by estimating the density of a transformed random vari able, and then taking the inverse transform. A new and efficient circular transform is proposed and investigated in this paper

＜正＞From among various surface planarization methods,BPSG-deposition and reflow has been widely accepted in the case of shallow junction VLSI technology to ensure;continuity and uniformity of metal interconnects over steps and dry etched vertical contact walls. From the point of view of subsequent processing results and finally of yield the most important properties of the BPSG.

Fiber lasers are a paradigm of dissipative systems,which distinguish themselves from a Hamilton system where energy is ***,pulses generated in a fiber laser are always accompanied by the continuous wave(CW).Under certain hypothesis,pulses generated in a fiber laser can be considered as a soliton,a product of a Hamilton ***,all the descriptions of solitons of a fiber laser are *** of solitons and the CW from a fiber laser prevents unveiling of real nonlinear dynamics in fiber lasers,such as soliton *** behavior in a fiber laser can be represented by the state of single pulse,the state of period doubling of single pulse,the states of two pulses either tightly bound or loosely distributed,the states of three pulses,and various combinations of the above-mentioned ***,soliton distillation was proposed and numerically demonstrated based on the nonlinear Fourier transform(NFT)[*** technol.39,2542(2021)].Solitons can be separated from the coherent CW ***,it is feasible to isolate solitons from CW background in a fiber ***,we applied the NFT to various pulses generated in a fiber laser,including single pulse,single pulse in period doubling,different double pulses,and multiple ***,with the approach of soliton distillation,the corresponding pure solitons of those pulses are *** results suggest that the NFT can be used to identify soliton dynamics excluding CW influence in a fiber laser,which paves a new way for uncovering real soliton interaction in nonlinear systems.
