Composed of pure and rigorous forms - an iron tubular frame, a sphere in etched glass containing light, and metal disks - Heis incorporates in the concept the statement that establishes the limits of knowledge and measurement of a physical system.
This is the first time that Bohinc explores a design favourite; the chair, Bohinc Studio in collaboration with Matter of Stuff. In the collection, Lara Bohinc develops her stellar themes, finding inspiration in planetary and lunar orbits, whose gravitationally curved trajectories drive the lines and shapes of the chairs. Constructed from thin square rod, the chairs are elegant, minimal and delicate. They are finished in galvanised steel and wool fabrics from Kvadrat. The Solar chair has an asymmetric frame and its reflecting circles suggest the rising and setting of the sun. It is constructed from playful lines that incorporate circles, half circles and squares.
This William Plunkett sofa, model Kingston, was made in 1967. The design incorporates individual upholstered parts, and the frame and legs are made of aluminum, steel, and chrome. The sofa was reupholstered some years ago in black leather and has been cleaned and polished. The curved design and thick, padded seats make the sofa both sturdy and comfortable.
Spectral methods, particularly in their multidomain version, have become firmly established as a mainstream tool for scientific and engineering computation. While retaining the tight integration between the theoretical and practical aspects of spectral methods that was the hallmark of their 1988 book, Canuto et al. now incorporate the many improvements in the algorithms and the theory of spectral methods that have been made since then. This second new treatment, Evolution to Complex Geometries and Applications to Fluid Dynamics, provides an extensive overview of the essential algorithmic and theoretical aspects of spectral methods for complex geometries, in addition to detailed discussions of spectral algorithms for fluid dynamics in simple and complex geometries. Modern strategies for constructing spectral approximations in complex domains, such as spectral elements, mortar elements, and discontinuous Galerkin methods, as well as patching collocation, are introduced, analyzed, and demonstrated by means of numerous numerical examples. Representative simulations from continuum mechanics are also shown. Efficient domain decomposition preconditioners (of both Schwarz and Schur type) that are amenable to parallel implementation are surveyed. The discussion of spectral algorithms for fluid dynamics in single domains focuses on proven algorithms for the boundary-layer equations, linear and nonlinear stability analyses, incompressible Navier-Stokes problems, and both inviscid and viscous compressible flows. An overview of the modern approach to computing incompressible flows in general geometries using high-order, spectral discretizations is also provided. The recent companion book Fundamentals in Single Domains discusses the fundamentals of the approximation of solutions to ordinary and partial differential equations on single domains by expansions in smooth, global basis functions. The essential concepts and formulas from this book are included in the current text for the reader s convenience.
