The Fundamentals and Applications of Light-Emitting Diodes: The Revolution in the Lighting Industry examines the evolution of LEDs, including a review of the luminescence process and background on solid state lighting. The book emphasizes phosphor-converted LEDs that are based on inorganic phosphors but explores different types of LEDs based on inorganic, organic, quantum dots, perovskite-structured materials, and biomaterials. A detailed description is included about the diverse applications of LEDs in fields such as lighting, displays, horticulture, biomedicine, and digital communication, as well as challenges that must be solved before using LEDs in commercial applications. Traditional light sources are fast being replaced by light-emitting diodes (LEDs). The fourth generation of lighting is completely dominated by LED luminaires. Apart from lighting, LEDs have extended their hold on other fields, such as digital communications, horticulture, medicine, space research, art and culture, display devices, and entertainment. The technological promises offered by LEDs have elevated them as front-runners in the lighting industry.
An examination of the process of prioritizing private motorized transportation in Bengaluru, a rapidly growing megacity of the Global South.Automobiles and their associated infrastructures, deeply embedded in Western cities, have become a rapidly growing presence in the mega-cities of the Global South. Streets once crowded with pedestrians, pushcarts, vendors, and bicyclists are now choked with motor vehicles, many of them private automobiles. In this book, Govind Gopakumar examines this shift, analyzing the phenomenon of automobility in Bengaluru (formerly known as Bangalore), a rapidly growing city of about ten million people in southern India. He finds that the advent of automobility in Bengaluru has privileged the mobility needs of the elite while marginalizing those of the rest of the population. Gopakumar connects Bengaluru's burgeoning automobility to the city's history and to the spatial, technological, and social interventions of a variety of urban actors. Automobility becomes a juggernaut, threatening to reorder the city to enhance automotive travel. He discusses the evolution of congestion and urban change in Bengaluru; the "regimes of congestion" that emerge to address the issue; an "infrastructurescape" that shapes the mobile behavior of all residents but is largely governed by the privileged; and the enfranchisement of an "automotive citizenship" (and the disenfranchisement of non-automobile-using publics). Gopakumar also finds that automobility in Bengaluru faces ongoing challenges from such diverse sources as waste flows, popular religiosity, and political leadership. These challenges, however, introduce messiness without upsetting automobility. He therefore calls for efforts to displace automobility that are grounded in reordering the mobility regime, relandscaping the city and its infrastructures, and reclaiming streets for other uses.
The absence of water supply infrastructure is a critical issue that affects the sustainability of cities in the developing world and the quality of life of millions of people living in these cities. Urban India has probably the largest concentration of people in the world lacking safe access to these infrastructures.This book is a unique study of the politics of water supply infrastructures in three metropolitan cities in contemporary India – Bangalore, Chennai and Kochi. It examines the process of change in water supply infrastructure initiated by notable Public Private Partnership’s efforts in these three cities to reveal the complexity of state-society relations in India at multiple levels – at the state, city and neighbourhood levels. Using a comparative methodology, the book develops as understanding of the changes in the production of reform water policy in contemporary India and its reception at the sub-national (state) level. It goes on to examine the governance of regimes of water supply in Bangalore, Chennai and Kochi, and evaluates the role of the partnerships in reforming water supply. The book is a useful contribution to studies on Urban Development and South Asian Politics.

An attempt is made to include as much recent material as possible so tghat students are exposed to the recent advances in this exciting field. The reference list at the end of each chapter is more elaborate than what is common for a typical textbook. The listing of recent research papers should be useful for researchers using the book as a reference. A set of problems is included at the end of each chapter. Telecommunication Systems is devoted to the systems design issues with emphasis on WDM systems. It includes a discussion of the dispersive and nonlinear effects (including polarization-mode dispersion) that affect the quality of the signal as it is transmitted through optical fibers.

The Peasants of Ottobeuren offers an interesting perspective on one of the enduring problems of early modern European history: the possibilities for economic growth and social change in rural society. Based on the voluminous records of the Swabian Benedictine monastery of Ottobeuren, this study underscores the limitations of the traditional narrative of a sixteenth-century boom which foundered on the productive rigidities of the peasant economy and then degenerated into social crisis in the seventeenth century. Population growth did strain resources at Ottobeuren, but the peasantry continued to produce substantial agricultural surplus. More importantly, peasants reacted to demographic pressure by deepening their involvement in land and credit markets, and more widely and aggressively marketing the fruits of their labour. Marriage and inheritance underwent a similar process of commercialization which made heavy demands on the peasantry, but which maintained a degree of social stability through the devastations of war, plague and famine.

Optical materials with varying refractive indices are called graded-index (GRIN) media and they are widely used within many industries, including telecommunications and medical imaging. Another recent application is space division multiplexing, an enormously improved technique for optical data transmission. This book synthesises recent research developments in this growing field, presenting both the underlying physical principles behind optical propagation in GRIN media, and the most important engineering applications. The principles of wave optics are employed for solving Maxwell's equations inside a GRIN medium, ensuring that diffractive effects are fully included. The mathematical development builds gradually and a variety of exact and approximate techniques for solving practical problems are included, in addition to coverage of modern topics such as optical vortices, photonic spin-orbit coupling, photonic crystals, and metamaterials. This text will be useful for graduate students and researchers working in optics, photonics and optical communications.
