The First Hands-On, Practical, All-Ruby Refactoring Workbook! Refactoring—the art of improving the design of existing code—has taken the world by storm. So has Ruby. Now, for the first time, there’s a refactoring workbook designed from the ground up for the dynamic Ruby language. Refactoring in Ruby gives you all the realistic, hands-on practice you need to refactor Ruby code quickly and effectively. You’ll discover how to recognize “code smells,” which signal opportunities for improvement, and then perfect your program’s design one small, safe step at a time. The book shows you when and how to refactor with both legacy code and during new test-driven development, and walks you through real-world refactoring in detail. The workbook concludes with several applications designed to help practice refactoring in realistic domains, plus a handy code review checklist you’ll refer to again and again. Along the way, you’ll learn powerful lessons about designing higher quality Ruby software—lessons that will enable you to experience the joy of writing consistently great code. Refactoring in Ruby will help you Recognize why poor code design occurs, so you can prevent it from occurring in your own code Master better design techniques that lead to more efficient, reliable, and maintainable software Fix code that’s too long, large, or difficult to follow Ferret out duplication, and express each idea “once and only once” Recognize missing or inadequately formed classes Simplify overly complex relationships between classes and their subclasses Achieve the right balance of responsibilities among objects Make your code easier to test and change Cope with incomplete library modules, and fix runaway dependencies Learn the next steps to take after you refactor
Design Patterns in JavaTM gives you the hands-on practice and deep insight you need to fully leverage the significant power of design patterns in any Java software project. The perfect complement to the classic Design Patterns, this learn-by-doing workbook applies the latest Java features and best practices to all of the original 23 patterns identified in that groundbreaking text. Drawing on their extensive experience as Java instructors and programmers, Steve Metsker and Bill Wake illuminate each pattern with real Java programs, clear UML diagrams, and compelling exercises. You'll move quickly from theory to application–learning how to improve new code and refactor existing code for simplicity, manageability, and performance. Coverage includes Using Adapter to provide consistent interfaces to clients Using Facade to simplify the use of reusable toolkits Understanding the role of Bridge in Java database connectivity The Observer pattern, Model-View-Controller, and GUI behavior Java Remote Method Invocation (RMI) and the Proxy pattern Streamlining designs using the Chain of Responsibility pattern Using patterns to go beyond Java's built-in constructor features Implementing Undo capabilities with Memento Using the State pattern to manage state more cleanly and simply Optimizing existing codebases with extension patterns Providing thread-safe iteration with the Iterator pattern Using Visitor to define new operations without changing hierarchy classes If you're a Java programmer wanting to save time while writing better code, this book's techniques, tips, and clear explanations and examples will help you harness the power of patterns to improve every program you write, design, or maintain.

Designed primarily as a text this volume is an up-to-date and integrated overview of physiological sleep mechanisms, brain function, psychological ramifications of sleep, dimensions of dreaming, and clinical disorders associated with sleep. It is accessibly written with specially boxed material that enhances the text. Authored by a researcher/clinician/professor with more than 25 years of experience in sleep studies, Understanding Sleep and Dreaming provides a solid basis for those who are not expert in this area. It offers a good foundation for those who will continue sleep studies, while at the same time offering enough information for those who will apply this knowledge in other ways such as clinicians in their individual practices or researchers for whom sleep may be part of a specific study. It is an excellent text for courses on sleep at the undergraduate and graduate levels.
The ability to understand the area of fluid mechanics is enhanced by using equations to mathematically model those phenomena encountered in everyday life. Helping those new to fluid mechanics make sense of its concepts and calculations, Introduction to Fluid Mechanics, Fourth Edition makes learning a visual experience by introducing the types of pr
Essentials of Polysomnography is a 615-page full color text designed specifically for sleep technicians and professionals. This textbook is written by William H Spriggs, an experienced author and instructor in polysomnography, and is used in hospitals, sleep labs, physician offices, and colleges and universities around the world. Essentials of Polysomnography is the first book to include the new recording and scoring rules presented in 2007, as well as the latest sleep disorder definitions and categorization presented in 2005. This text is designed around the board exam for sleep technicians, and includes 500 questions with answers and explanations. It is also ideal for training new sleep technicians and students interested in studying polysomnography, as well as physicians, sleep lab managers, DME reps, and sleep lab front office staff members.
For nearly 30 years, Dr. Meir Kryger’s must-have guide to sleep medicine has been the gold standard in this fast-changing field. This essential, full-color reference includes more than 20 unique sections and over 170 chapters covering every aspect of sleep disorders, giving you the authoritative guidance you need to offer your patients the best possible care. Evidence-based content helps you make the most well-informed clinical decisions. An ideal resource for preparing for the sleep medicine fellowship examination. New content on sleep apnea, neurological disorders, legal aspects of sleep medicine, dental sleep medicine genetics, circadian disorders, geriatrics, women’s health, cardiovascular diseases, and occupational sleep medicine, keeps you fully up to date. Updates to scientific discoveries and clinical approaches ensure that you remain current with new knowledge that is advancing the diagnosis and management of sleep disorders.
Introduction to Fluid Mechanics, Sixth Edition, is intended to be used in a first course in Fluid Mechanics, taken by a range of engineering majors. The text begins with dimensions, units, and fluid properties, and continues with derivations of key equations used in the control-volume approach. Step-by-step examples focus on everyday situations, and applications. These include flow with friction through pipes and tubes, flow past various two and three dimensional objects, open channel flow, compressible flow, turbomachinery and experimental methods. Design projects give readers a sense of what they will encounter in industry. A solutions manual and figure slides are available for instructors.
