S21  Vibrações e Análise Modal    Titulo: AN HIGH PERFORMANCE COMPUTATIONAL APPROACH IN SUBSPACES METHODS FOR DATA MODELLING   Resumo : IDENTIFICATION OF MULTIPLE INPUT MULTIPLE OUTPUT LINEAR TIME INVARIANT DYNAMICAL SYSTEM FROM INPUT-OUTPUT DATA SEQUENCES IS A CENTRAL PROBLEM IN SIGNAL PROCESSING AND IN CONTROL SYSTEMS ANALYSIS AND DESIGN. ROUGHLY SPEAKING, THIS PROBLEM IS EQUIVALENT TO FIND A REALIZATION FOR A DYNAMICAL SYSTEM IN ORDER TO REPRESENT INPUT OUTPUT DATA SEQUENCES. IN THIS WAY A REALIZATION IS A CHOICE OF A QUADRUPLE OF MATRICES THAT CAN REPRESENT INPUT OUTPUT DATA WITHIN AN ACCEPTABLE ERROR. FURTHER, THE FORMULATION PRESENTED IN THIS WORK LEADS TO A NICE APPROACH FOR ENGINEERING APPLICATIONS. IN THIS WORK, WE PRESENT A NEW METHODOLOGY USING PARALELL AND DISTRIBUTED COMPUTATION FOR PROCESSING VERHAEGEN & DEWILDE S ALGORITHM FOR STATE SPACE DATA MODELLING.
