Inference of a Susceptible-Infectious stochastic model
Giuseppina Albano, Virginia Giorno, Francisco Torres-Ruiz
We consider a time-inhomogeneous diffusion process able to describe the dynamics of infected people in a susceptible-infectious epidemic model in which the transmission intensity f…
Study of a general growth model
G. Albano, V. Giorno, P. Román-Román +1
We discuss a general growth curve including several parameters, whose choice leads to a variety of models including the classical cases of Malthusian, Richards, Gompertz, Logistic…
Inference on an heteroscedastic Gompertz tumor growth model
Giuseppina Albano, Virginia Giorno, Patricia Román-Román +3
We consider a non homogeneous Gompertz diffusion process whose parameters are modified by generally time-dependent exogenous factors included in the infinitesimal moments. The prop…
M/M/1 queue in two alternating environments and its heavy traffic approximation
Antonio Di Crescenzo, Virginia Giorno, Balasubramanian Krishna Kumar +1
We investigate an M/M/1 queue operating in two switching environments, where the switch is governed by a two-state time-homogeneous Markov chain. This model allows to describe a sy…
A continuous-time Ehrenfest model with catastrophes and its jump-diffusion approximation
Selvamuthu Dharmaraja, Antonio Di Crescenzo, Virginia Giorno +1
We consider a continuous-time Ehrenfest model defined over the integers from -N to N, and subject to catastrophes occurring at constant rate. The effect of each catastrophe instant…
A double-ended queue with catastrophes and repairs, and a jump-diffusion approximation
Antonio Di Crescenzo, Virginia Giorno, Balasubramanian Krishna Kumar +1
Consider a system performing a continuous-time random walk on the integers, subject to catastrophes occurring at constant rate, and followed by exponentially-distributed repair tim…
