Biosensors in food safety and quality have become indispensable in today’s world due to the requirement of food safety and security for human health and nutrition. This book covers various types of sensors and biosensors that can be used for food safety and food quality monitoring, but these are not limited to conventional sensors, such as temperature sensors, optical sensors, electrochemical sensors, calorimetric sensors, and pH sensors. The chapters are framed in a way that readers can experience the novel fabrication procedures of some advanced sensors, including lab-on-a-chip biosensors, IoT-based sensors, microcontroller-based sensors, and so on, particularly for fruits and vegetables, fermented products, plantation products, dairy-based products, heavy metal analysis in water, meat, fish, etc. Its simplistic presentation and pedagogical writing provide the necessary thrust and adequate information for beginners, scientists, and researchers.

The book offers comprehensive coverage of the most essential topics, which include the following:

This book serves as a reference for scientific investigators who work on the assurance of food safety and security using biosensing principles as well as researchers developing biosensors for food analysis. It may also be used as a textbook for graduate-level courses in bioelectronics.

This book is intended as an undergraduate/postgraduate level textbook for courses on high-speed optical networks as well as computer networks. Nine chapters cover the basic principles of the technology and different devices for optical networks, as well as processing of integrated waveguide devices of optical networks using different technologies. It provides students, researchers and practicing engineers with an expert guide to the fundamental concepts, issues and state-of-the-art developments in optical networks. It includes examples throughout all the chapters of the book to aid understanding of basic problems and solutions.

P. P. Sahu received his M.Tech. degree from the Indian Institute of Technology Delhi and his Ph.D. degree in engineering from Jadavpur University, India. In 1991, he joined Haryana State Electronics Development Corporation Limited, where he has been engaged in R&D works related to optical fiber components and telecommunication instruments. In 1996, he joined Northeastern Regional Institute of Science and Technology as a faculty member. At present, he is working as a professor in the Department of Electronics and Communication Engineering, Tezpur Central University, India. His field of interest is integrated optic and electronic circuits, wireless and optical communication, clinical instrumentation, green energy, etc. He has received an INSA teacher award (instituted by the highest academic body Indian National Science Academy) for high level of teaching and research. He has published more than 90 papers in peer-reviewed international journals, 60 papers in international conference, and has written five books published by Springer Nature, McGraw-Hill. Dr Sahu is a Fellow of the Optical Society of India, Life Member of Indian Society for Technical Education and Senior Member of the IEEE.

This book is intended as a graduate/post graduate level textbook for courses on high-speed optical networks as well as computer networks. The ten chapters cover basic principles of the technology as well as latest developments and further discuss network security, survivability, and reliability of optical networks and priority schemes used in wavelength routing. This book also goes on to examine Fiber To The Home (FTTH) standards and their deployment and research issues and includes examples in all the chapters to aid the understanding of problems and solutions.

This book presents an in-depth treatment of routing and wavelength assignment for optical networks, and focuses specifically on quality-of-service and fault resiliency issues. It reports on novel approaches for the development of routing and wavelength assignment schemes for fault-resilient optical networks, which improve their performance in terms of signal quality, call blocking, congestion level and reliability, without a substantial increase in network setup cost.

The book first presents a solution for reducing the effect of the wavelength continuity constraint during the routing and wavelength assignment phase. Further, it reports on an approach allowing the incorporation of a traffic grooming mechanism with routing and wavelength assignment to enhance the effective channel utilization of a given capacity optical network using fewer electrical-optical-electrical conversions. As a third step, it addresses a quality of service provision scheme for wavelength-division multiplexing (WDM)-based optical networks. Lastly, the book describes the inclusion of a tree-based fault resilience scheme in priority-based dispersion-reduced wavelength assignment schemes for the purpose of improving network reliability, while maintaining a better utilization of network resources.

Mainly intended for graduate students and researchers, the book provides them with extensive information on both fundamental and advanced technologies for routing and wavelength assignment in optical networks. The topics covered will also be of interest to network planners and designers.
