Underwater SLAM for Structured Environments Using an Imaging Sonar

David Ribas, Pere Ridao, José Neira, "Underwater SLAM for Structured Environments Using an Imaging Sonar"
Publisher: S/r | 2010 | ISBN: 3642140394 | 150 pages | PDF | 5 MB

This book is a revised version of the doctoral dissertation presented by D. Ribas in the Department of Computer Engineering at the University of Girona. The main purpose of this work is to present different techniques developed with the objective of providing a solution to the navigation problem for Autonomous Underwater Vehicles (AUVs) operating in structured environments, with special attention to localization techniques but, particularly, to the application of SLAM (Simultaneous Localization And Mapping) techniques as a self-contained system which requires neither previous knowledge of the scenario nor the use of absolute positioning systems like GPS, LBL or USBL. This book also presents techniques for feature extraction capable of dealing with the particular complexities of a mechanically scanned imaging sonar. The approaches described in this book are designed for use in structured environments like those present in many industrial scenarios, specifically for scenarios containing manmade structures in the form of rectilinear walls like those met in harbours, breakwaters, marinas, canal systems, etc. Although most of the previous work done in this field focuses on open sea and coastal applications, obtaining an accurate positioning in such scenarios would increase AUVs capabilities notably, allowing to perform autonomously tasks such as inspection of underwater structures, surveillance of marine installations and even enabling autonomous harbour leaving and returning operations

Urban Drainage (Spon Text)

http://avaxhome.ws/ebooks/engeneering_technology/UrbanDST.html
David Butler, John Davies, "Urban Drainage (Spon Text)"
Publisher: S...p...on | 2010 | ISBN: 041545526X | PDF | 656 pages | 5.2 MB

This new edition has been thoroughly revised and updated to reflect changes in the practice and priorities of urban drainage. New and expanded coverage includes:
- sewer flooding
- the impact of climate change
- flooding models
- the move towards sustainability.
Pring a descriptive overview of the issues involved as well as the engineering principles and analysis, it draws on real-world examples as well as models to support and demonstrate the key issues facing engineers dealing with drainage issues. It also deals with both the design of new drainage systems and the analysis and upgrading of existing infrastructure.
A unique and essential textbook for students of water, environmental and public health engineering as well as a valuable resource for practising engineers.
