  • For simple applications, switching devices such as contactors or solid-state relays can be used to control electrical power. The electrical power in a process can be regulated by varying the ON and OFF times of these devices. But in many processes this provision of energy in large blocks will cause significant variations in the process output. As an example, it would not be possible to control lighting levels simply by using such two-state on/off switching elements. Neither could good temperature controllers be implemented in this way...

  • Light is essential to sight. Without light there is no sight, at least not with our natural eyes. Because figure drawing begins with seeing, a book about figure drawing should have some significant information on the nature of light and how our eyes perceive it. Understanding how light works on objects in a scene helps the artist create a feeling of depth and substance in a drawing. In Figure 7.1 the lighting on the dress indicates that it is a dark satin material. In nature the artist often doesn’t have much control over the lighting of a scene. About...

  • We normally think of the eye as an organ for vision, but due to the discovery of additional nerve connections from recently-detected novel photoreceptor cells in the eye to the brain, it is now understood how light also mediates and controls a large number of biochemical processes in the human body. The most important findings are related to the control of the biological clock and to the regulation of some important hormones through regular light-dark rhythms. This in turn means that lighting has a large influence on health, well-being and alertness.

  • When planning how to reduce the threat of global warming and how to adapt to it, a very important piece of information is how intense the change will be. That implies estimating the trends of future concentrations of greenhouse gasses, and the potential future changes in temperature, precipitation, storm events and other climatic variables. These predictions are important not only to estimate the magnitude of the changes, but also to determine the uncertainty surrounding them.

  • Light and dark, hot and cold or the cyclical change of the seasons: the rotation and inclination of the Earth give rise to constantly recurring changes that, in the course of evolution, have resulted in human beings developing a circadian system – a system of internal clocks that anticipate such changes. Like the complex movement of a clock, it controls and coordinates the 24-hour variation of all bodily functions.

  • The world economy consists of two countries, denominated home and foreign. Each country is populated by a continuum of identical households, ¯rms, and a monetary authority. House- holds consume two types of ¯nal goods, a tradable good T and a nontraded good N. The production of nontraded goods requires capital and labor, and the production of tradable consumption goods requires the use of home and foreign traded inputs as well as nontraded goods.

  • Generally the term photonic crystal refers to two dimensional (2-D) and three dimensional (3-D) structures. Using 2-D and 3-D photonic crystals it is possible to control the propagation of light at arbitrary angles of incidence and not only the light normally incident as is the case for conventional optical films. Further, using photonic crystals, it is possible to achieve optical functionality not possible using conventional optical materials. This book provides a complete overview about photonic crystals including properties, applications, approaches and methods for the study....
