Finally a book on Wireless Sensor Networks that covers real world applications and contains practical advice! Kuorilehto et al. have written the first practical guide to wireless sensor networks. The authors draw on their experience in the development and field-testing of autonomous wireless sensor networks (WSNs) to offer a comprehensive reference on fundamentals, practical matters, limitations and solutions of this fast moving research area. Ultra Low Energy Wireless Sensor Networks in Practice: Explains the essential problems and issues in real wireless sensor networks, and analyzes the most promising solutions. Provides a comprehensive guide to applications, functionality, protocols, and algorithms for WSNs. Offers practical experiences from new applications and their field-testing, including several deployed networks. Includes simulations and physical measurements for energy consumption, bit rate, latency, memory, and lifetime. Covers embedded resource-limited operating systems, middleware and application software. Ultra Low Energy Wireless Sensor Networks in Practice will prove essential reading for Research Scientists, advanced students in Networking, Electrical Engineering and Computer Science as well as Product Managers and Design Engineers.
Wireless sensor network (WSN) is an ad-hoc network technology comprising even thousands of autonomic and self-organizing nodes that combine environmental sensing, data processing, and wireless networking. The applications for sensor networks range from home and industrial environments to military uses. Unlike the traditional computer networks, a WSN is application-oriented and deployed for a specific task. WSNs are data centric, which means that messages are not send to individual nodes but to geographical locations or regions based on the data content. A WSN node is typically battery powered and characterized by extremely small size and low cost. As a result, the processing power, memory, and energy resources of an individual sensor node are limited. However, the feasibility of a WSN lies on the collaboration between the nodes. A reference WSN node comprises a Micro-Controller Unit (MCU) having few Million Instructions Per Second (MIPS) processing speed, tens of kilobytes program memory, few kilobytes data memory. In addition, the node contains a short-range radio, and a set of sensors. Supply power is typically obtained with small batteries. Assuming a target lifetime of one year using AA-size batteries, the available power budget is around 1 mW. This book covers the low-power WSNs services ranging from hardware platforms and communication protocols to network deployment, and sensor data collection and actuation. The implications of resource constraints and expected performance in terms of throughput, reliability and latency are explained. As a case study, this book presents experiments with low-energy TUTWSN technology to illustrate the possibilities and limitations of WSN applications.
This book is one of the first to focus on Medieval and Early Modern state formation on the north-eastern periphery of Europe. Researchers have traditionally perceived an East-West conflict between Sweden and Novgorod concerning the late medieval colonization of the northern forest areas, but it seems that the East Fennoscandian boreal forest zone was not an unpopulated area at that time, but was a landscape inhabited by heterogeneous hunting and fishing populations and possessing another kind of culture. The ways of life of these populations can be observed by coordinating various bodies of palaeoecological, palaeobotanic, genetic, meteorological, folkloristic, philological and archaeological material. The traditional written sources did not extend to this area, and its nature is only reflected in the expansion and organization of the European Christian culture and power, both Russian and Swedish. Also, the increasing number of source documents, the growing population as reflected in those written documents and the expansion of arable cultivation do not indicate any real colonization but simply a change of the existing economic system from a semi-nomadic hunting and fishing economy to a field-based agriculture in response to the expansion of regular taxation and state control. Seen from this perspective, the people who earlier were invisible gradually become visible in the sources. The East Fennoscandian boreal forest zone was a European periphery during the Viking Age, but was connected to the European exchange of goods through the same waterways that also brought the first Christian cultural impact. The European economic crisis of the 14th Century nevertheless excluded the area from the late medieval process of state formation, and it became an object of both Muscovite and Swedish interests only after the end of the 15th Century. This meant the formation of parishes, the organization of an early local administration with regular taxation, the permanent stationing of military forces, the establishment of a physical border, and the assimilation of the local people into European culture, accompanied by marginalization of the traditional forms of life.
A History of Architectural Conservation expands knowledge about the conservation of ancient monuments, works of art and historic buildings. It includes the origins of the interest in conservation within the European context, and the development of the concepts from Antiquity and the Renaissance to the present day. Jokilehto illustrates how this development has influenced international collaboration in the protection and conservation of cultural heritage, and how it has formed the principal concepts and approach to conservation and restoration in today's multi-cultural society. This book is based on archival research of original documents and the study of key restoration examples in countries that have influenced the international conservation movement. Accessible and of great interest to students and the general public it includes conservation trends in Europe, the USA, India, Iran and Japan.
The first book to provide a full history of the development of architectural conservation, A History of Architectural Conservation is considered a landmark publication by architectural conservation students and professionals the world over. Twenty years after its first publication, this new edition of Jukka Jokilehto’s groundbreaking book continues the story to bring the history of architectural conservation right up to the modern day. Jokilehto draws on his distinguished career of over 40 years at ICCROM (International Centre for the Study of the Preservation and Restoration of Cultural Property, founded by UNESCO) to provide studies from Europe, the Middle East, the USA, Japan, India, China, Australia and South America. This accessible and well-written introduction to the history and theory of architectural conservation is richly illustrated in full colour and will be an essential go-to guide for students and practitioners worldwide.
