Optimal Control of Production Systems with Unreliable Machines and Finite Buffers
In this paper we present a novel formulation for the optimal control of discrete event dynamic processes which represent production systems with unreliable machines and buffers of...

Pfaffian Hybrid Systems
It is well known that in an o-minimal hybrid system the continuous and discrete components can be separated, and therefore the problem of finite bisimulation reduces to the same pr...

Bounds on Sizes of Finite Bisimulations of Pfaffian Dynamical Systems
We study finite bisimulations of dynamical systems in Rn defined by Pfaffian maps. The pure existence of finite bisimulations for a more general class of o-minimal systems was show...

Upper and Lower Bounds on Sizes of Finite Bisimulations of Pfaffian Dynamical Systems
In this paper we study a class of dynamical systems defined by Pfaffian maps. It is a sub-class of o-minimal dynamical systems which capture rich continuous dynamics and yet can be...

Tracking dynamics of topic trends using a finite mixture model
In a wide range of business areas dealing with text data streams, including CRM, knowledge management, and Web monitoring services, it is an important issue to discover topic tren...
