The origins of turbulent ?ow and the transition from laminar to turbulent ?ow are the most important unsolved problems of ?uid mechanics and aerodynamics.

To celebrate the sesquicentennial of Helmholtz's paper, IUTAM sponsored a symposium that was held at the technical university of Denmark in October 2008. This volume contains the papers presented as lectures at the symposium on Point vortices, vortex sheets, vortex filaments, vortex rings, vortex patches, and vortex streets.

This Symposium provided an international forum for exchange of ideas and creation of knowledge in recent advances on Multi-Functional Material Structures and Systems. Novel theories, mathematical models, analyses, and application of computational and experimental methods are topics treated. In particular, this work reflects the state of the art in mathematical modeling, computational methods, new experimental methods, new and advanced engineering applications in emerging technologies advanced sensors, structural health monitoring, MEMS, and advanced control systems.

Comprises papers based on some of the talks presented at the IUTAM Symposium of the same name, held in Cape Town, January 14-18, 2008. This book discusses various issues in modeling, the behavior of various classes of inelastic media, and associated algorithms for carrying out computational simulations.

Contains papers on the main topics reflecting the scientific programme of the symposium: hierarchical, refined mathematical and technical models of shells, plates, and beams; relation of 2D and 1D models to 3D linear, non-linear and physical models; junction problems.

To successfully design and fabricate novel nanomaterials and nanosystems, we must necessarily bridge the gap in our understanding of mechanical properties and processes at length scales ranging from 100 nanometers (where atomistic simulations are currently possible) to a micron (where continuum mechanics is experimentally validated).

Solid cellular materials (foams, lattice materials, honeycombs, etc.) are attractive and have resulted in the creation of an active subject for structural, mechanical and material scientists in recent years.

Scaling methods apply wherever there is similarity across many scales or one need to bridge different scales, e. The emphasis in the Symposium was upon fundamental issues such as: mathematical foundations of scaling methods based on transformations and connections between multi-scale approaches and transformations.

Covers the IUTAM Symposium held in Corfu in 2007 aimed at achieving a unified approach which regroups the knowledge coming from theoretical, experimental, numerical simulation, modeling and flow-control aspects of separated unsteady flows with respect to incompressible and compressible flow regimes.

The Symposium brought together many of the world's experts in fluid mechanics, microfabrication and control theory to discover the synergy that can lead to real advances and perhaps find ways in which collaborative projects may proceed. The high profile meeting was attended by keynote speakers who are leaders in their fields.

This is a state-of-the-art treatise on the problems of both nonlinearity and uncertainty in the dynamics and control of engineering systems. The concept of dynamics and control implies the combination of dynamic analysis and control synthesis.

Topics covered in particular include multi-scale particle methods for numerical simulations, liquid-wall interactions and modeling approaches, modeling of immersed nano-scale structures, organized flow behavior at micro and nano-scales, and methods for control of micro- and nano-scale flows.

The origins of turbulent ?ow and the transition from laminar to turbulent ?ow are the most important unsolved problems of ?uid mechanics and aerodynamics.
