Fractal-shot-noise Driven Doubly Stochastic Poisson Point Process
نویسندگان
چکیده
We explore the behavior of the fractal-shot-noise driven doubly stochastic Poisson point process or FSNDP, for which the associated impulse response functions assume a decaying power-law form. For a variety of parameters of the process, we obtain expressions for the count number distribution and moments, Fano factor, normalized coincidence rate, power spectral density, and time probability densities. A number of these measures exhibit power-law dependencies, indicating fractal behavior. For certain parameters the power spectral density exhibits 1=f-type behavior over a substantial range of frequencies, so that the process serves as a 1=f point process for in the range 0 < < 2. We consider two physical processes that are well described by FSNDP: Cherenkov radiation from a random stream of charged particles, and di usion of randomly injected concentration packets.

Interevent-time statistics for shot-noise-driven self-exciting point processes in photon detection
Probability densities for interevent time are obtained for a doubly stochastic Poisson point process (DSPP) in the presence of self-excitation. The DSPP is assumed to have a stochastic rate that is a filtered Poisson point process (shot noise). The model of a Poisson process driving another Poisson process produces a pulse-bunching effect. Self-excitation (relative refractoriness) results in a ...
متن کاملA note on bounds and monotonicity of spatial stationary Cox shot noises
We consider shot-noise processes and max-shot-noise processes driven by spatial stationary Cox (doubly stochastic Poisson) processes. We derive the upper and lower bounds of them in terms of the increasing convex order, which is known as the order relation to compare the variability of random variables. Furthermore, under some regularity assumption of the random intensity fields of Cox processe...
متن کاملDoubly Stochastic Poisson Process and the Pricing of Catastrophe Reinsurance Contract
We use a doubly stochastic Poisson process (or the Cox process) to model the claim arrival process for catastrophic events. The shot noise process is used for the claim intensity function within the Cox process. The Cox process with shot noise intensity is examined by piecewise deterministic Markov process theory. We apply the Cox process incorporating the shot noise process as its intensity to...

and key words Thirty years ago, Bernard Picinbono and his colleagues carefully addressed an important problem : how an optical field is converted into a sequence of photoelectrons upon detection . Their choice of problem could not have been better, nor thei r timing more judicious. In a paper entitled "Photoelectron Shot Noise", published in the Journal of Mathematical Physics in 1970, when qua...
متن کاملStatistical properties of a nonstationary Neyman - Scott cluster process
The Neyman-Scott cluster point process, originally developed in 1958 to describe the distribution of galaxies in space [l], has become an important representation for a broad range of phenomena in the physical, biological, and social sciences [2], [3]. Bartlett [4] has shown that the shot-noise driven doubly stochastic Poisson point process (SNDP) is a special but important example of a Neyman-...
