De Gregorio Alessandro; Professore Associato. Per una storia intellettuale del Rinascimento europeo, Pisa 2014 The aim of this note is to deepen the knowledge of isotropic random flights moving in mixed Poisson media; that is we analyze the random evolution of a particle with random scattering rate Λ. Explicit governing equations derived. The nonlocal porous medium equation considered in this paper is a degenerate nonlinear evolution equation involving a space pseudo-differential operator of fractional order. Roberto Di Gregorio is lid van Facebook. By assuming Λ distributed according to some standard probability laws, we are able to explicit the probability measure of the random flights. To this aim, we propose the whole class of pseudo $\phi$-divergence test statistics, which include as a special case the well-known likelihood ratio test but also many other test statistics as well as new ones.

Purpose: 1 paper we study the large time asymptotic behavior of random flights. The aim of this paper is to introduce a new type of test statistic for simple null hypothesis on one-dimensional ergodic diffusion processes sampled at discrete times. Join Facebook to connect with Greg Sapienza and others you may know. The aim of this paper is to derive the explicit distribution of the position of randomly moving particles on the line and in the plane (with different velocities taken cyclically) by means of order statistics and by studying suitable problems of differential equations. Statistica Gestionale. These facts, as well as the conclusions of other authors (9,24,26), forced us to use electrophysiological methods (PERG and PVEP) to determine the level and depth of damage in various types of hypertensive glaucoma (27)(28). The substances were administered topically as eye drops as well as an ocular eye bath.

The random flight model represents a random motion at finite speed of a particle with changes of direction governed by a Poisson process with parameter λ>0. The drug was administered at the dose of 1 gm for ten consecutive days. Stoch.

We consider a dynamical system with small noise for which the drift is parametrized by a finite dimensional parameter. Piaia, Gregorio, Sapienza e follia. The purpose of the study was to assess the effect of ibopamine (3,4 di-isobutyrrylester of N-methyldopamine), a D1-dopamine agonist, on intraocular pressure (IOP) in offspring of parents with primary openangle glaucoma as a consequence of outflow structures impairment. Didattica De Gregorio. Infer. obtained. The process describes the position of a particle moving on the real line, alternatively with constant velocity +v or -v. The changes of direction are governed by an homogeneous Poisson process with rate lambda > 0.

The purpose of this study was to compare psychophysical and electrophysiological testings in early optic nerve dysfunction in a group of clinically asymptomatic subjects with suspect ocular hypertension (OHT). Cerca nel sito. The first part has already been concluded while the second one is much more involving. The aim of the present preliminary study, performed on post-surgical hypotony, was the evaluation of the effects on ocular hypotony of the concomitant administration of ibopamine and corticosteroids.
