this paper presents an efficient global meta-model building technique for solving high fidelity multidisciplinary design optimization (mdo) problems. the main difficulties associated with mdo are often characterized by interdisciplinary couplings, high computational cost of an analysis in individual disciplines and a large number of design variables and constraints. these issues result in very ...

We propose a new method called Stochastic Model Reference Adaptive Search (SMRAS) for finding a global optimal solution to a stochastic optimization problem in situations where the objective functions cannot be evaluated exactly, but can be estimated with some noise (or uncertainty), e.g., via simulation. SMRAS is a generalization of the recently proposed Model Reference Adaptive Search (MRAS) ...

with me his happiness to life. A special thanks to Giuseppina for her tender support in important and difficult moments. Finally, I would like to express my deep gratitude to my parents, my sister and my wife, Mariafelicia, for their constant love and help in finding my way through life.

In the acquisition of skills requiring periodic body movements such as in cascade juggling, the establishment of stable body movements seems crucial. We investigated the processes of developing stable body movements in each of the three learning stages defined by the framework established by Beek and Van Santvoord (1992). We focused on two types of stability: stability of the body’s physical ce...
