Power Prediction Modeling of Conventional High-Speed Craft
The proposed book addresses various power prediction methods, a principal design objective for high-speed craft of displacement, semi-displacement, and planing type. At the core of the power prediction methods are mathematical models based on experimental data derived from various high-speed hull and propeller series. Regression analysis and Artificial Neural Network (ANN) methods are used as extraction tools for this kind of models. The most significant factors for in-service power prediction are bare hull resistance, dynamic trim, and the propeller's open-water efficiency. Therefore, mathematical modeling of these factors is a specific focus of the book. Furthermore, the book includes a su...

The History and Evolution of Tourism
This book provides an overview of the history and evolution of tourism to the present, and speculates on possible and probable change into the future. It discusses significant travel, tourism and hospitality events while referring to tourism-related notions and theories that have been developed since the beginnings of tourism. Its scope moves beyond a comprehensive historical account of facts and events. Instead, it bridges these with contemporary issues, challenges and concerns, hence enabling readers to connect tourism past with the present and future. This textbook aspires to enhance readers' comprehension of the perplexed system of tourism, promoting decision-making and even the development of new theories. This book will be of great interest to academics, practitioners and students from a wide variety of disciplines, including tourism, hospitality, events, sociology, psychology, philosophy, history and human geography.
Marine Propellers and Propulsion
The early development of the screw propeller. Propeller geometry. The propeller environment. The ship wake field, propeller performance characteristics.
Ship Resistance and Propulsion
Written by experts in the ship design field, this book provides a comprehensive approach to evaluating ship resistance and propulsion.
A Trip Too Far
Environmentally-sustainable tourism or ecotourism has become a major area of interest for governments, the private sector and international lending institutions. It is regarded as a way of allowing economic development whilst protecting against environmental degradation, especially in those countries with fragile ecosystems. However, despite the beneficial intentions of ecotourism, it tends to be regarded uncritically by environmental organizations, governments and the private sector alike. Rosaleen Duffy presents this analysis of ecotourism, linking it with environmental ideologies and the politics of North-South relations. By the extensive use of case study and interview material, she formulates ideas and proposals that should be important for the development of ecotourism around the globe.
Marine Mammals and Noise
Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.
