A heart-breaking, heart-warming novel for everyone of 10 and older – this book will probably make you cry, and will definitely make you laugh.Cymbeline Igloo (yes, really!) has NEVER been swimmingNot ever. Not once.But how hard can it be? He’s Googled front crawl and he’s found his dad’s old pair of trunks. He’s totally ready.What he’s not ready for is the accident at the pool – or how it leads his mum to a sudden breakdown.Now, with the help of friends old and new, Cymbeline must solve the mystery of why his mum never took him near water – and it will turn his whole life upside down…‘A wonderful story, moving and funny’ – Ross Welford

Praise for How to Sell Your Home Without a Broker «On a scale of 1 to 10, this book is a 10.» —Robert Bruss Jump into the real estate game—and win big! Home values are crashing and foreclosures are way up. You might think this is a terrible time to get into the real estate market—but you'd be wrong! A crashing real estate market offers plenty of opportunity to profit, if you know how to change your strategy and adjust to the new market reality. In The All-New Real Estate Foreclosure, Short-Selling, Underwater, Property Auction, Positive Cash Flow Book, top real estate investors and authors Chantal and Bill Carey show you how to get in safely and get out profitably. They present four new strategies for taking advantage of today's high foreclosure rate and explain how to invest for the long-term as the market resets to more realistic levels. Novice investors will find plenty of strategies for profiting without risking all they have, and old hands will find new, unconventional techniques that will help them continue to profit even if the market continues to struggle. Inside, you'll learn how to: Combine short-term and long-term investing strategies for cash flow today and tomorrow Buy mortgages in foreclosure at rock-bottom short-sale prices Avoid dealing with lenders by using the seller as your banker Utilize the right type of real estate auction for your investment needs Maximize your cash flow for big profits now and in the future Prepare yourself to profit from rising prices and near-term inflation Whether you're a first-timer or an experienced real estate pro, this is the ultimate guide to getting into the real estate market safely and cheaply—and getting out rich!

Due to the wave of refinancing in recent years, and the fall in home values, in 2009 about 12 million homeowners and investors will be «underwater»–owing more than their property is worth. This book explains all the options for these homeowners who are trapped with houses they want to get free from, people whose property value has dropped so low that they can't sell the property, people whose mortgage payment has adjusted and now they can't afford the property. In addition to offering advice on subject to's, rentals, leases, loan modifications and more…the book will teach America how to short sale their own home.

Offering complete and comprehensive coverage of modern sonar spectrum system analysis, Underwater Acoustics: Analysis, Design and Performance of Sonar provides a state-of-the-art introduction to the subject and has been carefully structured to offer a much-needed update to the classic text by Urick. Expanded to included computational approaches to the topic, this book treads the line between the highly theoretical and mathematical texts and the more populist, non-mathematical books that characterize the existing literature in the field. The author compares and contrasts different techniques for sonar design, analysis and performance prediction and includes key experimental and theoretical results, pointing the reader towards further detail with extensive references. Practitioners in the field of sonar design, analysis and performance prediction as well as graduate students and researchers will appreciate this new reference as an invaluable and timely contribution to the field. Chapters include the sonar equation, radiated, self and ambient noise, active sonar sources, transmission loss, reverberation, transducers, active target strength, statistical detection theory, false alarms, contacts and targets, variability and uncertainty, modelling detections and tactical decision aids, cumulative probability of detection, tracking target motion analysis and localization, and design and evaluation of sonars

Sonar and Underwater Acoustics brings together all the concepts necessary for designers and users of sonar systems. Unlike other books on this subject, which are often too specialized, this book is accessible to a wider audience. The first part focuses on the acoustic environment, antenna structures, and electric acoustic interface. The latter provides knowledge required to design, as well as the development and implementation of chain processes for an active sonar from the conditioning input to output processing. The reader will find a comprehensive range of all problems encountered in underwater acoustics for a sonar application, from physical phenomena governing the environment and the corresponding constraints, through to the technical definition of transducers and antennas, and the types of signal processing involved. In one section, measures in underwater acoustics are also proposed.

A blend of introductory material and advanced signal processing and communication techniques, of critical importance to underwater system and network development This book, which is the first to describe the processing techniques central to underwater OFDM, is arranged into four distinct sections: First, it describes the characteristics of underwater acoustic channels, and stresses the difference from wireless radio channels. Then it goes over the basics of OFDM and channel coding. The second part starts with an overview of the OFDM receiver, and develops various modules for the receiver design in systems with single or multiple transmitters. This is the main body of the book. Extensive experimental data sets are used to verify the receiver performance. In the third part, the authors discuss applications of the OFDM receiver in i) deep water channels, which may contain very long separated multipath clusters, ii) interference-rich environments, where an unintentional interference such as Sonar will be present, and iii) a network with multiple users where both non-cooperative and cooperative underwater communications are developed. Lastly, it describes the development of a positioning system with OFDM waveforms, and the progress on the OFDM modem development. Closely related industries include the development and manufacturing of autonomous underwater vehicles (AUVs) and scientific sensory equipment. AUVs and sensors in the future could integrate modems, based on the OFDM technology described in this book. Contents includes: Underwater acoustic channel characteristics/OFDM basics/Peak-to-average-ratio control/Detection and Doppler estimation (Doppler scale and CFO)/Channel estimation and noise estimation/A block-by-block progressive receiver and performance results/Extensions to multi-input multi-output OFDM/Receiver designs for multiple users/Cooperative underwater OFDM (Physical layer network coding and dynamic coded cooperation)/Localization with OFDM waveforms/Modem developments A valuable resource for Graduate and postgraduate students on electrical engineering or physics courses; electrical engineers, underwater acousticians, communications engineers
