A Stochastic Differential Equation SIS Epidemic Model

open access: yesSIAM Journal on Applied Mathematics, 2011
In this paper we extend the classical susceptible-infected-susceptible epidemic model from a deterministic framework to a stochastic one and formulate it as a stochastic differential equation (SDE) for the number of infectious individuals $I(t)$. We then

A Stochastic Model for Financiers

open access: yes, 2007
Si illustrano due modelli di comportamento, il primo per il finanziatore legale ed il secondo per quello illegale evidenzindone i fondamentali scopi di tali soggetti economici e quindi le conseguenti peculiarità dei due modelli.

Stochastic Models for Phototaxis

Bulletin of Mathematical Biology, 2008
This work studies two mathematical models for describing the motion of phototactic bacteria, i.e., bacteria that move toward light. Based on experimental observations, we conjecture that the motion of the colony toward light depends on certain group dynamics. These group dynamics are hypothesized to be coordinated through an individual property of each

Stochastic Deformable Model

Procedings of the British Machine Vision Conference 2005, 2005
Deformable or active contour, and surface models are powerful image segmentation techniques. We introduce a novel fast and robust bi-directional parametric deformable model which is able to segment regions of intricate shape in multi-modal greyscale images.

A Stochastic Model for Auditing

The Journal of the Operational Research Society, 1992
Auditing is based on random sampling from the records of a company. This paper considers a Bayesian model for determining the sample sizes by finding a balance between the cost of sampling and the risk of leaving major faults undiscovered. It leads to a dynamic programming problem which involves substantial computations, but a slightly different ...
