This book is designed to serve as a textbook for courses offered to upper-undergraduate students enrolled in physics and explains the broad spectrum of optics in a student-friendly way. The textbook covers the entire syllabi of the undergraduate courses being taught at both national and international universities including adequate details of mathematical expressions to help students understand the subject matter. The topics covered in this book are reflection, refraction, cardinal points, interference, Fresnel diffraction, Fraunhofer diffraction, lasers and holography, fiber optics, etc.

This book explains each topic in a simple and lucid language with the help of solved problems. Exercises with multiple choice questions have been given at the end of each chapter for self-assessment. The detailed coverage and pedagogical tools make this an ideal textbook for students and researchers enrolled in senior undergraduate and beginning postgraduate physics students.

This monograph presents a comprehensive study of portfolio optimization, an important area of quantitative finance. Considering that the information available in financial markets is incomplete and that the markets are affected by vagueness and ambiguity, the monograph deals with fuzzy portfolio optimization models. At first, the book makes the reader familiar with basic concepts, including the classical mean–variance portfolio analysis. Then, it introduces advanced optimization techniques and applies them for the development of various multi-criteria portfolio optimization models in an uncertain environment. The models are developed considering both the financial and non-financial criteria of investment decision making, and the inputs from the investment experts. The utility of these models in practice is then demonstrated using numerical illustrations based on real-world data, which were collected from one of the premier stock exchanges in India. The book addresses both academics and professionals pursuing advanced research and/or engaged in practical issues in the rapidly evolving field of portfolio optimization.

This book provides the latest information on trans-Himalayan Hindu Kush Region (HKR) fisheries including the Indian Himalayan Region (IHR) as well as the historical context of its sustainable development for improving livelihood and nutritional security. The book serves as an important document to provide knowledge and information about the major concerns of environmental and anthropogenic factors that have impacted the population of certain important fishes in the ecosystem and the strategies and policies required for the conservation of these important groups of fishes, viz., Mahseer, snow trout, minor carp, catfishes, etc. The chapters describe the information to the readers on potential cold water and cool water fish species suitable for large-scale farming and propagation addressing the issues of diseases, nutrigenomics, and nanobiotechnology. This book also addresses the prospects and potential of recreational fishing in India and the scope for its improvement to generate more employment and income citing the success stories and primary information from reputed anglers. Finally, the book also elucidates a comprehensive yet representative description of many challenges associated with inland coldwater- cool water fisheries and aquaculture in HKR, IHR, and its way forward.
