Managing data continues to grow as a necessity for modern organizations. There are seemingly infinite opportunities for organic growth, reduction of costs, and creation of new products and services. It has become apparent that none of these opportunities can happen smoothly without data governance. The cost of exponential data growth and privacy / security concerns are becoming burdensome. Organizations will encounter unexpected consequences in new sources of risk. The solution to these challenges is also data governance; ensuring balance between risk and opportunity. Data Governance, Second Edition, is for any executive, manager or data professional who needs to understand or implement a data governance program. It is required to ensure consistent, accurate and reliable data across their organization.

A Comprehensive Guide to Radiographic Sciences and Technology is a concise review of radiographic physics and imaging, perfect for students preparing for certification examinations such as the American Registry for Radiologic Technologists (ARRT). Aligned with the core radiographic science components of the current American Society of Radiologic Technologists (ASRT) curriculum, this up-to-date resource covers topics including radiation production and characteristics, imaging equipment, digital image acquisition and display, radiation protection, basic principles of computed tomography, and quality control. The guide begins with an overview of the radiographic sciences and technology, followed by detailed descriptions of the major components of digital radiographic imaging systems. Subsequent sections discuss the essential aspects of diagnostic radiography and computed tomography, including basic physics, imaging modalities, digital image processing, quality control, imaging informatics, and basic concepts of radiobiology and radiation protection. Throughout the book, concise chapters summarise the critical knowledge required for effective and efficient imaging of the patient while emphasising the important, yet commonly misunderstood, relationship between radiation dose and image quality. Written by an internationally recognised expert in the field, this invaluable reference and guide: Provides easy access to basic physics, techniques, equipment, and safety guidelines for radiographic imaging Reflects the educational requirements of the American Society of Radiologic Technologists (ASRT), the Canadian Association of Medical Radiation Technologists (CAMRT), the College of Radiographers (CoR), and other radiography societies and associations worldwide Offers a range of pedagogical tools such as chapter outlines, key term definitions, bulleted lists, practical examples, and links to current references and additional resources Includes charts, diagrams, photographs, and x-ray images A Comprehensive Guide to Radiographic Sciences and Technology is required reading for students in programs using ionizing radiation, those preparing for the ARRT and other global radiography certification exams, and practising technologists wanting to refresh their knowledge.

Imagine what you could do if scalability wasn't a problem. With this hands-on guide, you’ll learn how the Cassandra database management system handles hundreds of terabytes of data while remaining highly available across multiple data centers. This third edition—updated for Cassandra 4.0—provides the technical details and practical examples you need to put this database to work in a production environment. Authors Jeff Carpenter and Eben Hewitt demonstrate the advantages of Cassandra’s nonrelational design, with special attention to data modeling. If you’re a developer, DBA, or application architect looking to solve a database scaling issue or future-proof your application, this guide helps you harness Cassandra’s speed and flexibility. Understand Cassandra’s distributed and decentralized structure Use the Cassandra Query Language (CQL) and cqlsh—the CQL shell Create a working data model and compare it with an equivalent relational model Develop sample applications using client drivers for languages including Java, Python, and Node.js Explore cluster topology and learn how nodes exchange data

The present book focuses on recent advances methods and applications in photovoltaic (PV) systems. The book is divided into two parts: the first part deals with some theoretical, simulation and experiments on solar cells, including efficiency improvement, new materials and behavior performances. While the second part of the book devoted mainly on the application of advanced methods in PV systems, including advanced control, FPGA implementation, output power forecasting based artificial intelligence technique (AI), high PV penetration, reconfigurable PV architectures and fault detection and diagnosis based AI. The authors of the book trying to show to readers more details about some theoretical methods and applications in solar cells and PV systems (eg. advanced algorithms for control, optimization, power forecasting, monitoring and fault diagnosis methods). The applications are mainly carried out in different laboratories and location around the world as projects (Algeria, KSA, Turkey, Morocco, Italy and France). The book will be addressed to scientists, academics, researchers and PhD students working in this topic. The book will help readers to understand some applications including control, forecasting, monitoring, fault diagnosis of photovoltaic plants, as well as in solar cells such as behavior performances and efficiency improvement. It could be also be used as a reference and help industry sectors interested by prototype development.

This book is a comprehensive survey on safety for older adults. It contains contributions by experts from over a dozen disciplines, including physicians, audiologists, optometrists, mental health professionals, lawyers, occupational therapists, and policy makers. This multi-disciplinary approach provides a new and expansive conceptual framework for health care professionals, students, policymakers, and others who care for older adults, and promotes an understanding of the many challenges that adults face as they age. This book describes the complex range of issues that need to be considered when safeguarding older adults. We hope that this book will be of benefit to anyone currently working or training to work with older adults, helping them to fully appreciate the many safety issues that can arise. The book will be also be useful for both older adults and their caregivers, helping them to identify and address areas of concern. Our goal is to mitigate injury or other harm through an increased understanding of the risks encountered by older adults. This text will also appeal to professionals and graduate students in the fields of human factors and ergonomics, occupational health, and safety.
