1. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts
Abstract : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. READ MORE

3. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints
Abstract : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... READ MORE

4. Finite Element Procedures for the Numerical Simulation of CRack Propagation and Bilateral Contact
Abstract : This thesis concerns finite element methods for the numerical simulation of crack propagation including contact formulations for the contact between deformable bodies. The classical integral formulations for theenergy release rate at crack growth are considered and adaptive algorithms are developed. READ MORE

5. Statistical energy analysis and variational principles for the prediction of sound transmission in multilayered structures
Abstract : Multilayered structures have many application in industry and society: they have peculiar properties and serve a variety of purposes, like structural support, thermal insulation, vibrational and acoustic isolation. This thesis concerns the prediction of sound transmission in multilayered structures. READ MORE
