Microelectromenchanical systems (MEMS) is a revolutionary field that adapts for new uses a technology already optimized to accomplish a specific set of objectives. The silicon-based integrated circuits process is so highly refined it can produce millions of electrical elements on a single chip and define their critical dimensions to tolerances of 100-billionths of a meter. The MEMS revolution harnesses the integrated circuitry know-how to build working microsystems from micromechanical and microelectronic elements. MEMS is a multidisciplinary field involving challenges and opportunities for electrical, mechanical, chemical, and biomedical engineering as well as physics, biology, and chemistry. As MEMS begin to permeate more and more industrial procedures, society as a whole will be strongly affected because MEMS provide a new design technology that could rival - perhaps surpass - the societal impact of integrated circuits. |

Cooperating Embedded Systems and Wireless Sensor Networks
A number of different system concepts have become apparent in the broader context of embedded systems over the past few years. Whilst there are some differences between these, this book argues that in fact there is much they share in common, particularly the important notions of control, heterogenity, wireless communication, dynamics/ad hoc... | | Microsoft Visual Basic .NET 2003 Kick StartVisual Basic has slowly evolved over the years, incorporating a variety of features and moving itself into the world of "enterprise" development, but everything was being built on top of an already existing foundation. This is not unusual; most development tools progress in this way, but it has the unfortunate side... | | Ranking Queries on Uncertain Data (Advances in Database Systems)
Uncertain data is inherent in many important applications, such as environmental surveillance, market analysis, and quantitative economics research. Due to the importance of those applications and rapidly increasing amounts of uncertain data collected and accumulated, analyzing large collections of uncertain data has become an important task.... |
