Book Description
Provides a comprehensive and updated account of WDM optical network systems Optical networking has advanced considerably since 2010. A host of new technologies and applications has brought a significant change in optical networks, migrating it towards an all-optical network. This book places great emphasis on the network concepts, technology, and methodologies that will stand the test of time and also help in understanding and developing advanced optical network systems. The first part of Optical WDM Networks: From Static to Elastic Networks provides a qualitative foundation for what follows—presenting an overview of optical networking, the different network architectures, basic concepts, and a high-level view of the different network structures considered in subsequent chapters. It offers a survey of enabling technologies and the hardware devices in the physical layer, followed by a more detailed picture of the network in the remaining chapters. The next sections give an in-depth study of the three basic network structures: the static broadcast networks, wavelength routed networks, and the electronic/optical logically routed networks, covering the characteristics of the optical networks in the access, metropolitan area, and long-haul reach. It discusses the networking picture; network control and management, impairment management and survivability. The last section of the book covers the upcoming technologies of flex-grid and software defined optical networking. Provides concise, updated, and comprehensive coverage of WDM optical networks Features numerous examples and exercise problems for the student to practice Covers, in detail, important topics, such as, access, local area, metropolitan, wide area all-optical and elastic networks Includes protocols, design, and analysis along with the control and management of the networks Offers exclusive chapters on advance topics to cover the present and future technological trends, such as, software defined optical networking and the flexible grid optical networks Optical WDM Networks: From Static to Elastic Networks is an excellent book for under and post graduate students in electrical/communication engineering. It will also be very useful to practicing professionals in communications, networking, and optical systems.

Book Description
Rural residents have higher rates of age-adjusted mortality, disability, and chronic disease than their urban counterparts. Contributing negatively to the health status of rural residents are their lower socioeconomic status, higher incidence of both smoking and obesity, and lower levels of physical activity. Contributing negatively to the health status of farmers are the high risks from workplace hazards; contributing positively are farmers¿ higher socioeconomic status, lower incidence of smoking, and more active lifestyle. Both farm and rural populations experience lower access to health care along the dimensions of affordability, proximity, and quality, compared with their non-farm and urban counterparts. Charts and graphs.

Book Description
Access to broadband connectivity is a country s passport to the global information society and knowledge economy the future. However, the adoption and use of broadband technology today remains extremely uneven and threatens to create a new digital divide. At the end of 2009, countries in North America and the European Union accounted for more than 50 percent of the world s 1 billion fixed and mobile broadband subscriptions, but South Asia and Sub-Saharan Africa together accounted for less than 3 percent. The experience with mobile telephony though shows the potential for growth in the information and communication technology sector in developing countries. Almost 75 percent of the world s mobile telephone subscriptions are in low- and middle-income countries, which have also promoted exciting innovations and realized significant economic development benefits. In fact, a growing number of countries are seeking to spur broadband development. To aid governments as they design their own programs, this volume offers examples and ideas from some of the most successful broadband markets: particularly the Republic of Korea, but also Finland, France, Japan, Sweden, the United Kingdom, and the United States. 'Building Broadband' does not suggest a universal solution but rather provides a long list of policies and programs organized within a strategic framework that allows solutions tailored to country circumstances. The essential building blocks identified are useful everywhere because they focus on improving incentives and the climate for private investment. This is a policy that even countries with very limited resources will be able to exploit.
