Любимци в новините: постоянни и променливи величини

In 1999, in The Return of Depression Economics, Paul Krugman surveyed the economic crises that had swept across Asia and Latin America, and pointed out that those crises were a warning for all of us: like diseases that have become resistant to antibiotics, the economic maladies that caused the Great Depression were making a comeback. In the years that followed, as Wall Street boomed and financial wheeler-dealers made vast profits, the international crises of the 1990s faded from memory. But now depression economics has come to America: when the great housing bubble of the mid-2000s burst, the U.S. financial system proved as vulnerable as those of developing countries caught up in earlier crises and a replay of the 1930s seems all too possible.

In this new, greatly updated edition of The Return of Depression Economics, Krugman shows how the failure of regulation to keep pace with an increasingly out-of-control financial system set the United States, and the world as a whole, up for the greatest financial crisis since the 1930s. He also lays out the steps that must be taken to contain the crisis, and turn around a world economy sliding into a deep recession. Brilliantly crafted in Krugman's trademark style—lucid, lively, and supremely informed—this new edition of The Return of Depression Economics will become an instant cornerstone of the debate over how to respond to the crisis.

The first comprehensive book written about Radiosity. Features applications from the fields of computer graphics, architecture, industrial design, and related computer aided design technologies. Contains a chapter authored by Pat Hanrahan on the basic concepts of image synthesis and a foreword by Donald Greenberg.

Radiosity is a computer graphics technique which makes use a global illumination model to accurately represent the inter-reflection of light between surfaces. The technique produces view-independent results, so that most of the work is complete before viewing parameters are selected. This allows efficient interactive walk-throughs of simulated environments. However, radiosity is the most computationally expensive image generation technique. Most other image generation techniques make use of local illumination models and give faster image generation times.

The method is based on engineering techniques which were originally used to calculate radiant interchange between surfaces, for applications such as boiler and radiator design. The literature available has expanded rapidly in the past ten years and until now there has been no single comprehensive source describing the available techniques. This book is a comprehensive source and is written by respected names in the field of computer graphics.
