  • This work gives a survey of the results obtained in a series of papers by Boukrouche & Lukaszewicz (2004, 2005a,b, 2007) and Boukrouche, Lukaszewicz, & Real (2006) in which we consider the problem of the existence and finite dimensionality of attractors for some classes of twodimensional turbulent boundary-driven flows (Problems I–IV below). The flows admit mixed, non-standard boundary conditions and also time-dependent driving forces (Problems III and IV).

  • Cognitive linguistics has reached a stage of maturity where many researchers are looking for an explicit formal grounding of their work. Unfortunately, most current models of deep language processing incorporate assumptions from generative grammar that are at odds with the cognitive movement in linguistics. This demonstration shows how Fluid Construction Grammar (FCG), a fully operational and bidirectional unification-based grammar formalism, caters for this increasing demand.

  • Central to this book are two ideas. The first is that Fluid Mechanics is relevant to a wide variety of problems that are priorities in the early 21st century, three of which are health, the environment, and energy. The second idea is that researchers in this field are applying novel methods to address these problems. Even on its most basic level, Fluid Mechanics is challenging.
