This paper deals with the observer problem for dynamical systems in a behavioral context. We are given a dynamical system together with a partition of the system variables into a set of known or measured variables and a set of unknown, to be estimate

The problem of providing an adequate definition of a stochastic system is addressed and motivated using examples. A stochastic system is defined as a probability triple. The specification of the set of events is an essential part of a stochastic mode

We address the interconnection of stochastic systems. A stochastic system is defined as a probability triple. The specification of the set of events is an essential part of a stochastic model. Models often require a coarse event sigma-algebra. A stoc

Linear parameter-varying (LPV) systems are usually described in either state-space or input-output form. When analyzing system equivalence between different representations it appears that the time-shifted versions of the scheduling signal (dynamic d

In this paper we study the characterization of deterministic Markovian properties for 2D behavioral systems in terms of their descriptions by PDE's. In particular, we consider scalar systems and show that in this case strong-Markovianity is equivalen

The behavioral approach to dynamical systems is applied to electrical circuits. This offers an attractive way to introduce circuits pedagogically. An electrical circuit is a device that interacts with its environment through wires, called terminals.

In this paper, we study the structured nonnegative matrix factorization problem: given a square, nonnegative matrix P , decompose it as P = VAV ⊤ with V and A nonnegative matrices and with the dimension of A as small as possible. We propose an iter

In this paper we consider the following problem for hidden Markov models: given a minimal hidden Markov model, derive conditions for another hidden Markov model to be equivalent and give a description of the complete set of equivalent models. A disti

In linear system theory, we often encounter the situation of investigating some quadratic functionals which represent Lyapunov functions, energy storage, performance measures, e.t.c. Such a quadratic functional is called a quadratic differential form
