Lasers and Optical Fibre Communications is a self-contained book on lasers and fibre optics for physicists and engineering students at the introductory level. It presents the latest developments in laser technology in a concise and lucid manner. The first few chapters deal with the concepts such as lasers and their origin, theoretical concepts of laser technology and their applications to various spheres. This is followed up with an exhaustive study of the various laser schemes and different laser types. A separate chapter is devoted to the applications of laser technology in spheres such as science, technology, medicine and defence. Optical fibres are equally elegantly dealt with. In particular, Ray and Mode Theory, transmission characteristics, dispersion properties of optical wave guides, and the nature of detectors deserve special mention for the excellent treatment in the book. The gamut of communication systems including the nuances of laser propagation is also presented. The most important feature of the book is the seamless blending of theory with practice to bring out how the components of fibre systems are put together to achieve techno economic solution. The book concludes with a short note on holography and masers. This book will useful for students of B.Sc, M.Sc, B.Tech, B.E and M.Tech, practicing engineers and scientists.

The book is designed to serve as the first course for civil engineering students and a guide to design engineers. It is an outcome of more than 25 years of teaching of the subject to IIT Kanpur students and experience of field problems. Three basic methods of design, namely Working Stress Design (WSD), Limit State Design (LSD) and Ultimate Strength Design (USD) which are in practice are dealt with. The Limit State Design being the latest, very extensive presentation of the method applied to fully and partially prestressed concrete structures is made. An introduction to the probability failure analysis leading to the limit state concepts is illustrated along with some statistics of observations. Full and partial prestress designs based on the latest codes of practice are explained with a number of examples on variety of elements, such as beams, ties, columns, slabs, shells and bridges. Detailed design examples on minimum weight design of beams is presented to enable the students and designers to look for rational solutions. Cost analysis of components of materials and formwork in beams is illustrated. Some of the key features of the book are: 1. Discussion on limit state design of full and partial prestressed concrete beam. 2. Detailed examples of design of small to long span beams, water tanks, cylindrical shells, folded plates, domes and bridges are illustrated. 3. Latest codes of practice are incorporated and comparison of the designs based on different methods and illustrated. 4. Economical analysis and the influence of design variable and methods on cost are discussed. 5. Useful design aids for beams, cylindrical shells are given in appendices. 6. A set of objective questions which will enable a student or an engineer to find most rational solutions and concepts are listed in the appendix.

Brick and brick masonry is one of the most durable and widely used building and structural materials. This book has been developed not merely as a textbook for students but also as a guide to designers and builders. The book incorporates feedback from students while a course on structural design was taught, experience in testing of materials at the IIT Kanpur, and author s design expertise as a consultant. Many brick buildings have been analysed and their statistics have been presented. A certain amount of research component based on a sponsored project from the Department of Science and Technology, New Delhi has been added to enable engineers to get more depth in the subject. The first two chapters are an introduction to the properties of bricks, mortar and masonry. The histograms and statistical analyses give an insight of the chapter of brick and brick masonry in some parts of India. The third chapter presents the design of load-bearing brick walls and columns, and design of retaining walls. Design of reinforced brick slabs and beams is presented in chapter four. Some problems associated with reinforced brick construction have also been highlighted.

The author having been in the field of teaching, research and design for more than four decades has evolved the book to suit the needs of students and practising engineers. The book gives an in depth understanding of concepts, detailing and constructability of the, design; and enables the designer to approach an optimal solution. The continuous changes in design and construction practices are kept in mind in developing the theory and illustrative examples. Indian Code of Practice on Plain and Reinforced Concrete (IS: 456) revised in 2000 emphasizes durability considerations. The book is developed based on the latest concrete technology and codes of practices. The author's earlier books on the design of reinforced and prestressed concrete structures have been popular for many years because of the concepts and methodologies presented in systematic manner. The book highlights the importance of integrating structural systems through reinforcement details. Sometimes, engineers are misled by long output of computers that may or may not be relevant to the actual structure. It is important that the user of structural software has the foundations of structural analysis, design and synthesis before applying the software. The book is an excellent teacher and leader in concepts, design procedures, optimal designs and integrator of detailing of reinforcement.
