Dont let the title mislead. This book is about surfing and the people who lived the surfing experience in Australia in the 1970s and, through flashbacks, to as early as the 1950s. The title refers to the dilemma of the lead character, Alexander Scott. He is trapped by family circumstances in a place that can never satisfy his needs. He loses his father at a young age and is brought unwillingly out of a very sheltered upbringing. Though his stepfather cares for him, he is unable to provide the father figure Alex needs. Surfing provides the escape, but it also puts him in conflict with his family. When his mother passes away, his stepfather remarries, and Alex is left with two stepparents and a family to whom he cannot relate emotionally. His stepsister provides a partial bridge, but in reality, they are worlds apart. She is a product of the wealthy Sydney society while Alex prefers his surfing companions. When Alex meets Julianne Cameron, there is an instant rapport. She becomes the love of his life, and he sees a way to find the emotional peace he seeks. But Julianne is cruelly taken from him in an accident that leaves Alex with injuries from which he can never recover.

This book presents a comprehensive overview of the mathematics and physics behind the simulation of turbulent flows and discusses in detail (i) the phenomenology of turbulence in fluid dynamics, (ii) the role of direct and large-eddy simulation in predicting these dynamics, (iii) the multiple considerations underpinning subgrid modelling, and, (iv) the issue of validation and reliability resulting from interacting modelling and numerical errors.

Written from the expertise of an agricultural engineering background, this exciting new book presents the most useful numerical methods and their complete program listings.

Embedded controller electronics are at the heart of virtually all modern electronic devices today with a market of more than $86 billion per year and growing. To serve the needs of designers creating products for this huge market, this practical book covers topics crucial for modern electronics design. Author Jerry Twomey examines the methods necessary to help you create a trouble-free integrated system for your product, with an emphasis on hardware design. You'll explore topics from the perspective of real-world applications, including discussions about non-ideal components, noise, and methods for avoiding problematic scenarios. Topics include: Ideal versus actual connections, components, digital, signals Architecting an embedded system Digital interface selection by application, speed, distance Multivoltage power supplies High frequency power integrity Battery and charging systems EMI reduction and ESD protection Driving and sensing peripherals Digital feedback control Optimization of power consumption and cost Specialty systems: medical, industrial, aerospace PCB design including manufacturability, yield, and low noise This book guides you through all of the techniques listed, which are required for a reliable integrated system. Through extensive illustrations and minimal equations, anyone with an interest in electronics will quickly grasp the ideas discussed.
