The theory of water waves is most varied and is a fascinating topic. It includes a wide range of natural phenomena in oceans, rivers, and lakes. It is mostly concerned with elucidation of some general aspects of wave motion including the prediction of behaviour of waves in the presence of obstacles of some special configurations that are of interest to ocean engineers. Unfortunately, even the apparently simple problems appear to be difficult to tackle mathematically unless some simplified assumptions are made. Fortunately, one can assume water to be an incompressible, in viscid and homogeneous fluid. The linearised theory of water waves is based on the assumption that the amplitude of the motion is small compared to the wave length. If rotational motion is assumed, then the linearised theory of water waves is essentially concerned with solving the Laplace equation in the water region together with linearised boundary condition. There are varied classes of problems that have been/are being studied mathematically in the literature within the framework of linearised theory of water waves for last many years. Scattering by obstacles of various geometrical configurations is one such class of water wave problems. This book is devoted to advanced mathematical work related to water wave scattering. Emphasis is laid on the mathematical and computational techniques required to study these problems mathematically.The book contains nine chapters. The first chapter is introductory in nature. It includes the basic equations of linearised theory for a single layer fluid, a two-layer fluid, solution of dispersion equations, and a general idea on scattering problems and the energy identity in water with a free surface. Chapter 2 is concerned with wave scattering involving thin rigid plates of various geometrical configurations, namely, plane vertical barriers or curved barriers, inclined barriers, horizontal barrier, and also thin elastic vertical plate. For the horizontal case, the barrier is submerged below an ice-cover modelled as a thin elastic plate floating on water. Chapter 3 discusses wave scattering by a rectangular trench by using Galerkin technique. Chapter 4 involves wave scattering by a dock by using Carleman singular integral equation followed by reduction to Riemann-Hilbert problems. Chapter 5 involves several wave scattering problems involving discontinuities at the upper surface of water by using the Wiener-Hopf technique, by reduction to Carleman singular integral equations. Chapter 6 considers scattering by a long horizontal circular cylinder either half immersed or completely submerged. In chapter 7, some important energy identities are derived for scattering problems in a single-layer and also in a two-layer fluid. Chapter 8 is concerned with wave scattering in a two-layer fluid by a thin vertical plate and by a long horizontal circular cylinder submerged in either of the two layers. Chapter 9 is the final chapter which considers a number of wave scattering problems in a single-layer or a two-layer fluid with variable bottom topography by using a simplified perturbation analysisIt is hoped that this book will be useful to researchers on water waves. The several wave scattering problems presented in the book are mostly based on the research work carried out by the authors and their associates.
Mastering 3D Plant Engineering, Digitalisation & Automation
"In today's world, 3D modeling is rapidly replacing traditional 2D-based design and engineering. Given the vast array of capabilities and technical recalibration of engineering and design approaches that are using the 3D modeling framework, there is a pressing need to cohesively outline this domain knowledge. This book covers all the underlying concepts including the creation and application of 3D models, as well as leveraging on the data-driven intelligence concept including usage of various digitalization tools. Further, the data-driven concept has been explained in this book to highlight how it can be used for work-sharing by concurrently accessing the same model and database across various geographical locations and finally the deployment of overall project lifecycle management."

This book provides an in-depth exploration of the mathematical and theoretical foundations of quantum teleportation. Starting with the seminal 1993 work by C. H. Bennett and colleagues, this book delves into the intricate processes that enable the transfer of quantum information using non-local quantum entangled resources. It covers a broad spectrum of teleportation protocols for single and multi-qubit systems, explores the impact of quantum noise, and presents strategies to mitigate these effects. Overall features of this book are the following: • Detailed explanations of quantum mechanics concepts relevant to teleportation, such as qubits, entanglement, quantum evolution, noise, and measurement. • In-depth analysis of teleportation through noisy quantum channels, with models for amplitudedamping, bit-flip, phase-flip, and phase-damping noise. • Methods for minimizing the effects of noise, including weak and reversal measurements and environment- assisted techniques. • Case studies that illustrate the application of various teleportation protocols. • Comprehensive coverage of the necessary mathematics, including linear spaces, operators, tensor products, and partial trace operations. Primarily aimed at theoretical physicists, applied mathematicians, computer scientists, and engineers belonging to all branches of electrical technology, this book is both an introduction and a comprehensive guide to the field of quantum teleportation. It will also be beneficial to the interested scientientists and professionls belonging to physical chemistry, material science and information technology.
Retaining F-22a Tooling: Options and Costs

The last F-22A aircraft is scheduled for delivery in early 2012, so decisions must be made as to what tooling will be retained and what will be disposed of. The authors find that, for a modest, one-time additional cost of $17 million and a very small additional annual recurring cost, the Air Force can retain all F-22A unique government tools. They also find a difference of less than $1 billion between the costs of two different restart options.

When a weapon system ceases production, the tooling not needed for sustainment that cannot be repurposed must either be disposed of or stored. Storage is not free, but system-specific tooling might become necessary for a restart, and starting from scratch can be expensive, although some tools cost more to store than they are worth. The authors examine these tooling retention issues for the C-17 cargo aircraft.
