Stochastic Bridges of Linear Systems [PDF]
We study a generalization of the Brownian bridge as a stochastic process that models the position and velocity of inertial particles between the two end-points of a time interval. The particles experience random acceleration and are assumed to have known states at the boundary. Thus, the movement of the particles can be modeled as an Ornstein-Uhlenbeck

Methodological Tools for the Detection of Risks to the Welfare of the Individuals and the Territory of Residence [PDF]
To formalise the assessment of risks to the welfare of individuals and the territory of residence presents a relevant issue. This study aims to define the economic security in the structure of the system of the welfare of individuals and the territory ...

Existence and uniqueness of solutions for stochastic urban-population growth model
Urban-population growth model has attracted attention over the last few decades due to its usefulness in representing population dynamics, virus dynamics, and epidemics.

Efficient simulation of stochastic chemical kinetics with the Stochastic Bulirsch-Stoer extrapolation method [PDF]
BackgroundBiochemical systems with relatively low numbers of components must be simulated stochastically in order to capture their inherent noise. Although there has recently been considerable work on discrete stochastic solvers, there is still a need ...

Optimization of stochastic systems [PDF]
This paper gives a short survey of Monte Carlo algorithms for stochastic optimization. Both discrete and continuous parameter stochastic optimization are discussed, with emphasis on the analysis of convergence rate. Some future research directions for the area are also indicated.

A stochastic differential equation SIS epidemic model [PDF]
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

On dissipation in stochastic systems [PDF]
We define the property of dissipativity for controlled Ito diffusions. We investigate elementary properties, and we demonstrate that the framework is useful for control problems in which both probabilistic and worst-case representations of dynamic uncertainty are present. As an example we discuss a problem involving robust /spl Hscr//sub 2/ performance

How to Drive a Delayed Response, Stochastic System Close to Equilibrium [PDF]
We consider a continuous system that, in the absence of random perturbations and external forcing, is uniformly, asymptotically stable in a global sense. The system evolution is governed by a retarded differential equation.

The decomposition of stochastic systems
Using the deterministic framework of \textit{J. Hartmanis} and \textit{R. E. Stearns} [Algebraic structure theory of sequential machines (1966; Zbl 0154.417)] as a point of entry, the authors rely on use of an analogy to the substitution property to realize stochastic systems by the appropriate interconnection of smaller stochastic systems.
