Book Description
Static mixers are an attractive alternative for the mixing of chemicals in water treatment plants. The attraction comes from the fact that static mixers do not require an external input of energy and do not have moving parts. Static mixers consist of mixing elements fixed on the inside of a pipe of channel. The elements do not move. Chemicals, added just upstream of the mixers, mix with the bulk fluid because of the complex, three-dimensional fluid motion generated by the elements. The goal of this project is to explore the use of static mixers in two of the key processes in drinking water treatment: for the mixing of coagulants for destabilization and the mixing of disinfectants for the inactivation of Cryptosporidium parvum oocysts in disinfection. The role of mixing in both of these processes is not well understood. But for each process experimental and theoretical evidence suggests that, at least in some circumstances, the mixing environment provided when chemicals are introduced into the flow will affect the resulting destabilization or inactivation.

Book Description
In this rich study of noise in American film-going culture, Meredith C. Ward shows how aurality can reveal important fissures in American motion picture history, enabling certain types of listening cultures to form across time. Connecting this history of noise in the cinema to a greater sonic culture, Static in the System shows how cinema sound was networked into a broader constellation of factors that affected social power, gender, sexuality, class, the built environment, and industry, and how these factors in turn came to fruition in cinema's soundscape. Focusing on theories of power as they manifest in noise, the history of noise in electro-acoustics with the coming of film sound, architectural acoustics as they were manipulated in cinema theaters, and the role of the urban environment in affecting mobile listening and the avoidance of noise, Ward analyzes the powerful relationship between aural cultural history and cinema's sound theory, proving that noise can become a powerful historiographic tool for the film historian.

Book Description
Edward Scott continues to impress as a poet. Not missing a line, he picks up where he left off, a new book. His upgraded self-craft-style writing hasn't lightened up. Scott poetry just keeps rolling along. His writing isn't a form or style, certainly, nothing anyone has ever seen, but more or less an open conscience with an ego that demands print. In his latest book, STATIC, the poet unleashes a new collection of poems that embodies an intangible network of art in its own spectrum based on true authenticity, Scott's writing- a welcomed model to poetry.

Book Description
"It was strange - Wilt calling me when he'd died the week before. Maybe a lot of other people get called from the spirit world or whatever, but it was a first for me and so I didn't pick up until the fifth or sixth ring." When Curtis Brooks gets a phone call from his older brother Wilt the week after his funeral, he's sure his brother is reaching out from beyond the grave to find evidence that will lead to his murder's arrest. But Wilt claims he wasn't murdered; his calling is standard protocol for newly deceased at the Aftermart--a kind of inescapable, ever-expanding Walmart filled with obsolete technology and discontinued products. Curtis embarks on a dangerous plan to find the killer, which soon has him scheming against a billionaire and fumbling towards love with his brother's ex-girlfriend Suzy, all while struggling with typical high school drama and his single mom's questionable choices. Why does Wilt help Curtis win over Suzy, even as he organizes a rebellion at the Aftermart? Who wanted him dead? Curtis risks his life to answer these questions, in the process forging a bond with his brother unlike any they ever had.

Book Description
An introduction to dependent types, demonstrating the most beautiful aspects, one step at a time. A program's type describes its behavior. Dependent types are a first-class part of a language, and are much more powerful than other kinds of types; using just one language for types and programs allows program descriptions to be as powerful as the programs they describe. The Little Typer explains dependent types, beginning with a very small language that looks very much like Scheme and extending it to cover both programming with dependent types and using dependent types for mathematical reasoning. Readers should be familiar with the basics of a Lisp-like programming language, as presented in the first four chapters of The Little Schemer. The first five chapters of The Little Typer provide the needed tools to understand dependent types; the remaining chapters use these tools to build a bridge between mathematics and programming. Readers will learn that tools they know from programming—pairs, lists, functions, and recursion—can also capture patterns of reasoning. The Little Typer does not attempt to teach either practical programming skills or a fully rigorous approach to types. Instead, it demonstrates the most beautiful aspects as simply as possible, one step at a time.

Book Description
A self-contained introduction to abstract interpretation–based static analysis, an essential resource for students, developers, and users. Static program analysis, or static analysis, aims to discover semantic properties of programs without running them. It plays an important role in all phases of development, including verification of specifications and programs, the synthesis of optimized code, and the refactoring and maintenance of software applications. This book offers a self-contained introduction to static analysis, covering the basics of both theoretical foundations and practical considerations in the use of static analysis tools. By offering a quick and comprehensive introduction for nonspecialists, the book fills a notable gap in the literature, which until now has consisted largely of scientific articles on advanced topics. The text covers the mathematical foundations of static analysis, including semantics, semantic abstraction, and computation of program invariants; more advanced notions and techniques, including techniques for enhancing the cost-accuracy balance of analysis and abstractions for advanced programming features and answering a wide range of semantic questions; and techniques for implementing and using static analysis tools. It begins with background information and an intuitive and informal introduction to the main static analysis principles and techniques. It then formalizes the scientific foundations of program analysis techniques, considers practical aspects of implementation, and presents more advanced applications. The book can be used as a textbook in advanced undergraduate and graduate courses in static analysis and program verification, and as a reference for users, developers, and experts.

Book Description
Behavioral equations were developed for reinforced concrete deep beams, especially in the realm of shear capacity. A series of static and dynamic beam tests was performed to aid in the development of this objective. Static shear behavior equations for deep beams were derived on the lower boundary of reinforced concrete deep beam data represented by research from this report and other research comprising 73 tests. Equations for a total static shear capacity are given which conservatively predict shear capacities of the beam tests considered. (Author).
