The novel approach taken here banishes determinants to the end of the book and focuses on the central goal of linear algebra: understanding the structure of linear operators on vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. For example, the book presents - without having defined determinants - a clean proof that every linear operator on a finite-dimensional complex vector space (or an odd-dimensional real vector space) has an eigenvalue. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. This second edition includes a new section on orthogonal projections and minimization problems. The sections on self-adjoint operators, normal operators, and the spectral theorem have been rewritten. New examples and new exercises have been added, several proofs have been simplified, and hundreds of minor improvements have been made throughout the text.

    We are living in an age where data comes in abundance, and thanks to the self-learning algorithms from the field of machine learning, we can turn this data into knowledge. Automated speech recognition on our smart phones, web search engines, e-mail spam filters, the recommendation systems of our favorite movie streaming services – machine learning makes it all possible.Thanks to the many powerful open-source libraries that have been developed in recent years, machine learning is now right at our fingertips. Python provides the perfect environment to build machine learning systems productively.This book will teach you the fundamentals of machine learning and how to utilize these in real-world applications using Python. Step-by-step, you will expand your skill set with the best practices for transforming raw data into useful information, developing learning algorithms efficiently, and evaluating results.You will discover the different problem categories that machine learning can solve and explore how to classify objects, predict continuous outcomes with regression analysis, and find hidden structures in data via clustering.

    This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.

    After spending several months in New York City, the family signed up for a journey to the Republic of Texas where they could homestead and eventually acquire 137 free acres for their efforts. Soon growing discontented with, not only the land, but also the management of the colony in which they had settled, the Horns decided to return to England. But, it was not to be. Attacked and captured by a party of Comanche Indians, Sarah Ann was faced with challenges and realities the like of which she never could have dreamed. Over a period of fifteen months of Comanche captivity, she and her captors rode endlessly across the Texas plains until finally she was purchased out of bondage and befriended by traders in New Mexico. This is the true story of a remarkable woman who endured an unimaginable amount of suffering and pain in her short lifetime.

    Auditing is perhaps our single best defense in ensuring the integrity of our financial reporting system. That's why this new Eighth Edition of Boynton and Johnson's Modern Auditing focuses on decision making and the critical role auditors play in providing assurance about the integrity of the financial reporting system. Known for its clear writing and accessibility, this text provides comprehensive and integrated coverage of current developments in the environment, standards, and methodology of auditing. Features * Real-world examples relate issues discussed in the chapter to ethics, audit decision making, and the integrity of the financial reporting system. * Focus on Audit Decisions sections highlight key factors that influence an auditor's decisions. * Includes discussion of the role of the Public Company Accounting Oversight Board (PCAOB) Auditing Standards, and a chapter feature highlights PCAOB standards that differ from Generally Accepted Auditing Standards for private companies. * Expanded case material related to the integrated audit case (Mt. Hood Furniture) provides a variety of databases that allow students to utilize generalized audit software (IDEA) to accomplish various audit tasks. Multiple databases allow the case to be reused with different data from term to term. * A flowchart style chapter preview begins each chapter. * Chapter summaries reinforce important audit decisions included in the chapter. * End-of-chapter material organized by audit decisions provides a clear link between audit decisions discussed in each chapter and the problem material.

     Jordan Wylie, a young man from a tough area of Blackpool where kids like him often went off the rails, chose a life in the army. He saw service in Iraq and learned to cope with the horrors he'd witnessed, then suffered an injury that blocked any chance of climbing up the military ladder. But an old army colleague suggested he join a security team on a tanker in Yemen. Ex-servicemen were offered dazzling salaries and `James Bond' lifestyles between jobs protecting the super-tankers carrying consumer goods to Europe and the US. However, for the men tempted to go, the price they paid was the claustrophobia and isolation of life on board and the ever-present possibility of death skimming towards them across the vast, lonely blue sea. Jordan was one of these men. In Citadel, he writes the first account of these dangerous years from someone 'at the front'. A young soldier from the backstreets of Blackpool, he was determined to make the most of his life, but unsure of the way forward. To his surprise, he found his answers in the perilous waters of 'Pirate Alley'.
