This is mainly due to an increase in the European Commission funding of comparative research to investigate social problems across Europe and in particular around the issues of social exclusion and educational under-achievement (Coffield, 1999). In this c

General Formulation and Classification of Interaction Problems of a Shell with a Fluid Flow,r the case of an impermeable surface and an ideal fluid. Interaction of an impermeable shell with a liquid or gas can be described relatively simply and this represents an advantage in practice over the more complicated problem of a permeable shell. The theory of permeable shells interacting with a

Self-Excited Nonlinear Oscillations of Elastic Bodies in a Flow: An Introduction,ors, and aerodynamic nonlinearities for airfoils in transonic flow. For aeroelasticity of plates and shells, the equations of motion are well established. Results obtained by numerical time integration may be compared to those obtained by topological theories of dynamics and also from experiment. Al

Unsteady Transonic Aerodynamics and Aeroelasticity,transonic flow regime. This flow regime is often the most critical for aeroelastic phenomena yet it has proven the most difficult to master in terms of basic understanding of physical phenomena and the development of predictive mathematical models. The difficulty is primarily a result of the nonline

Chaotic Oscillations in Mechanical Systems,undamental understanding of why and when such oscillations occur is of great importance. This goal will be pursued here by considering the relationship between chaos induced by forced oscillations vs self-excited oscillations, the relationship of indeterminancy of the final equilibrium state in the
