Buffering

Many emerging technologies such as video conferencing, video-on-demand, and digital libraries require the efficient delivery of compressed video streams. For applications that require the delivery of compressed stored multimedia streams, the a priori knowledge available about these compressed streams can aid in the allocation of server and network resources. By using a client-side buffer, the resource requirements from the server and network can be minimized. Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems presents a comprehensive description of buffering techniques for the delivery of compressed, prerecorded multimedia data. While these techniques can be applied to any compressed data streams, this book focusses primarily on the delivery of video streams because of the large resource requirements that they can consume. The book first describes buffering techniques for the continuous playback of stored video sources. In particular, several bandwidth smoothing (or buffering) algorithms that are provably optimal under certain conditions are presented. To provide a well-rounded discussion, the book then describes extensions that aid in the ability to provide interactive delivery of video across networks. Specifically, reservation techniques that take into account interactive functions such as fast-forward and rewind are described. In addition, extensions to the bandwidth smoothing algorithms presented in the first few chapters are described. These algorithms are designed with interactive, continuous playback of stored video in mind and are also provably optimal under certain constraints. Buffering Techniques for Delivery of Compressed Video in Video-on-Demand Systems serves as an excellent resource for multimedia systems, networking and video-on-demand designers, and may be used as a text for advanced courses on the topic.

The comedian and Internet star shares her experiences with family, sexuality, mental health, friendship & love in this New York Times–bestselling memoir. The wildly popular YouTube personality, star of Food Network’s I Hart Food, and author of the New York Times–bestseller My Drunk Kitchen is back! This time, she’s stirring up memories and tales from her past. By combing through the journals that Hannah has kept for much of her life, this collection of narrative essays deliver a fuller picture of her life, her experiences, and the things she’s figured out about family, faith, love, sexuality, self-worth, friendship and fame. Revealing what makes Hannah tick, this sometimes cringe-worthy, poignant collection of stories is sure to deliver plenty of Hannah’s wit and wisdom, and hopefully encourage you to try your hand at her patented brand of reckless optimism. With a New Afterword by the Author “By turns hilarious and heartbreaking, Hannah Hart’s new book is a roaring, beautiful, and profoundly human account of an extraordinary life.” —John Green “Hannah shares her truth with an honesty that is inspiring—one that makes me believe her when she says that it’s going to get better or that laughter is just around the corner or that you aren’t alone.” —Jenny Lawson, #1 New York Times–bestselling author of Let’s Pretend This Never Happened and Furiously Happy “The topics are grim, but there is kindness in her story, and, most significantly, humor. Fans will be pleased that other stars such as comedian Grace Helbig make guest appearances, and, like a true role model, Hart uses her platform to raise awareness of the shortcomings of the current U.S. medical system in treating mental health.” —Publishers Weekly

Modern production systems have become more flexible and agile. For them, a suitable control and planning method is needed. Agent-based systems offer the required characteristics. The contributions of these work are a remodeling of the Shifting Bottleneck heuristic to include limited buffers, the development of a decentralized multi-agent system for production planning, and the adaptation of the heuristic to the agent system. It concludes with evaluations of real-world production systems.

Provides the tools needed to analyze and solve acid drainage problems Featuring contributions from leading experts in science and engineering, this book explores the complex biogeochemistry of acid mine drainage, rock drainage, and acid sulfate soils. It describes how to predict, prevent, and remediate the environmental impact of acid drainage and the oxidation of sulfides, offering the latest sampling and analytical methods. Moreover, readers will discover new approaches for recovering valuable resources from acid mine drainage, including bioleaching. Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils reviews the most current findings in the field, offering new insights into the underlying causes as well as new tools to minimize the harm of acid drainage: Part I: Causes of Acid Mine Drainage, Rock Drainage and Sulfate Soils focuses on the biogeochemistry of acid drainage in different environments. Part II: Assessment of Acid Mine Drainage, Rock Drainage and Sulfate Soils covers stream characterization, aquatic and biological sampling, evaluation of aquatic resources, and some unusual aspects of sulfide oxidation. Part III: Prediction and Prevention of Acid Drainage discusses acid-base accounting, kinetic testing, block modeling, petrology, and mineralogy studies. It also explains relevant policy and regulations. Part IV: Remediation of Acid Drainage, Rock Drainage and Sulfate Soils examines both passive and active cleanup methods to remediate acid drainage. Case studies from a variety of geologic settings highlight various approaches to analyzing and solving acid drainage problems. Replete with helpful appendices and an extensive list of web resources, Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils is recommended for mining engineers and scientists, regulatory officials, environmental scientists, land developers, and students.

Today, few texts offer a comprehensive overview of geographic information systems (GIS). The literature common in academic circles is highly technical and pays little attention to the role GIS plays as a tool in the planning and shaping of society and the world around us. The contributors to this book feel strongly about the potential inherent in the concepts and methodologies that make up a GIS. Similarly, the contributors are aware of the limitations of the uniformly technical and structural approach that dominates discussions about GIS in many professional circles. This book is a guide and an educational, easy-to-understand journey that introduces the concepts and methodologies that lie behind today's GIS. It makes GIS both more familiar and more relevant to a far broader section of the professional circles which plan, organize, and shape our surroundings.

Could you go through a day without accessing a single mobile app? Or without dishing a comment here and a swipe there? These are some of the questions that the 15 short stories in Buffering Love explore through the escapades of its protagonists on myriad mobile apps. Whether it's the tinsel town diva who accidentally tweets an intimate personal account, or the aspiring writer who opens a dating app in an office reception just before her interview, the characters from the world of Buffering Love cling on to their mobile phones, sometimes to crush reality and sometimes to embellish it. Set in urban India and replete with surprising turns, Buffering Love will delight and devastate its readers in equal measure.

This book provides a comprehensive overview of reaction processes in the Earth's crust and on its surface, both in the laboratory and in the field. A clear exposition of the underlying equations and calculation techniques is balanced by a large number of fully worked examples. The book uses The Geochemist's Workbench® modeling software, developed by the author and already installed at over 1000 universities and research facilities worldwide. Since publication of the first edition, the field of reaction modeling has continued to grow and find increasingly broad application. In particular, the description of microbial activity, surface chemistry, and redox chemistry within reaction models has become broader and more rigorous. These areas are covered in detail in this new edition, which was originally published in 2007. This text is written for graduate students and academic researchers in the fields of geochemistry, environmental engineering, contaminant hydrology, geomicrobiology, and numerical modeling.
