Multicentered Chicago

GROWTH OF THE METROPOLITAN AREA (MAP) E N T R I E S M Multicentered Chicago Next Chicagoans like to think of their home as “multiethnic,” or as “the city of neighborhoods.” Indeed, the celebration of neighborhood is one of the binding rituals of Chicago culture. The shelves of local bookstores are crammed with neighborhood guides of various sorts, and in the 1990s Mayor Richard M. Daley harness...

Sunlight , UV , & Accelerated Weathering

Sunlight is an important cause of damage to plastics, textiles, paints, and other organic materials. Short wavelength ultraviolet light has long been recognized as being responsible for most of this damage2. Spectroradiometric measurements were made to quantify the wide variations in UV content of sunlight under the following conditions: direct summer sunlight, winter sunlight, sunlight filtere...

Weathering of Chondritic Meteorites

Meteorites are frequently not the pristine record of early solar system processes that we would like them to be. Many unique meteorites, samples that can further our understanding of the environment of the early solar system, are finds, so a knowledge of terrestrial weathering becomes a requirement to accurately interpret their preterrestrial history. This chapter outlines the weathering proces...

Image-based Material Weathering

The appearance manifold [WTL∗06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in images in which weathering and shading variations are combined. In this paper, we present a technique for modeling and editing the weathering effects of an object in a single ima...
