On p-Optimal Proof Systems and Logics for PTIME
We prove that TAUT has a p-optimal proof system if and only if a logic related to least fixed-point logic captures polynomial time on all finite structures. Furthermore, we show ...

Set-valued methods for linear parameter varying systems,
We consider stability analysis and state feedback synthesis for Linear Parameter Varying (LPV) systems. LPV systems are de"ned as linear systems whose dynamics depend on exog...

Exponential Stability of Interval Dynamical Systems with Quadratic Nonlinearity
This article proposes an approach for investigating the exponential stability of a nonlinear interval dynamical system with the nonlinearity of a quadratic type on the basis of the...

Design Patterns for Collaborative Systems
Collaborative applications provide a group of users with the facility to communicate and share data in a coordinate way. In this paper we propose a pattern system to design the ba...
