Between the late fifteenth and early eighteenth centuries, the State of Muscovy emerged from being a rather homogenous Russian-speaking and Orthodox medieval principality to becoming a multi-ethnic and multi-religious empire. Not only the conquest of the neighbouring Tatar Khanates and the colonisation of Siberia demanded the integration of non-Christian populations into the Russian state. The ethnic composition of the capital and other towns also changed due to Muscovite policies of recruiting soldiers, officers, and specialists from various European countries, as well as the accommodation of merchants and the resettlement of war prisoners and civilians from annexed territories. The presenc...
The homogenization of single phase gases or liquids with chemical reactive components by mixing belongs to one of the oldest basic operations applied in chemical engineering. The mixing process is used as an essential step in nearly all processes of the chemical industry as well as the pharmaceutical and food ind- tries. Recent experimentally and theoretically based results from research work lead to a fairly good prediction of the velocity fields in differend kinds of mixers, where as predictions of simultaneously proceeding homogeneous chemical re- tions, are still not reliable in a similar way. Therefore the design of equipment for mixing processes is still derived from measurements of th...
During the 1970s todays Austrian Federal Ministry of Education, Science and Research (Bundesministerium für Bildung, Wissenschaft und Forschung, BMBWF) supported the founding of the Center for Austrian Studies at the University of Minnesota in Minneapolis and the Austrian Chair at Stanford University in California. These foundings were the initial incentives for the worldwide `spreading' of similar institutions; currently, nine Centers for Austrian and Central European Studies exist in seven countries on three continents. The funding of the Ministry enables to connect senior scholars with young scholars, to help young PhD students, to participate in and to benefit from the scientific connection of experienced researchers, and to get in touch with the national scientific community by `sniffing scientific air', as the Austrians like to say. Furthermore, it aims to avoid prejudices, and to spread a better understanding and knowledge about Austria and Central Europe by promoting scientific exchange.
From optical fundamentals to advanced applications, this comprehensive guide to micro-optics covers all the key areas for those who need an in-depth introduction to micro-optic devices, technologies, and applications. Topics covered range from basic optics, optical materials, refraction, and diffraction, to micro-mirrors, micro-lenses, diffractive optics, optoelectronics, and fabrication. Advanced topics, such as tunable and nano-optics, are also discussed. Real-world case studies and numerous worked examples are provided throughout, making complex concepts easier to follow, whilst an extensive bibliography provides a valuable resource for further study. With exercises provided at the end of each chapter to aid and test understanding, this is an ideal textbook for graduate and advanced undergraduate students taking courses in optics, photonics, micro-optics, microsystems, and MEMs. It is also a useful self-study guide for research engineers working on optics development.
Mit der netzwerkmäßigen Internationalisierung von Produktionsaktivitäten werden zwar Voraussetzungen für eine effektive und effiziente Produktion im globalen Wettbewerb geschaffen. Globale Produktionsnetzwerke erweisen sich allerdings bei kürzer werdenden Produktlebenszyklen und einer damit steigenden Bedeutung des Faktors Zeit als zunächst einmal kritisch hinsichtlich einer schnellen Markteinführung neuer Produkte. Denn gegenüber einer zentral angelegten Produktion sorgen sie je nach Konfiguration für einen gestiegenen und dabei zeitintensiveren Koordinationsbedarf. Das trifft insbesondere auf die Phase des Produktionsanlaufs neuer Produkte zu: In dieser zeitkritischen Phase ist ni...
