Book Description
Search and Rescue (SAR) planning and response activities are sometimes handicapped by the lack of environmental information. Accurate and comprehensive wind and current are necessary to determine the likely movement of search objects over time. To address this, the U.S. Coast Guard has deployed a new software tool for SAR planning, the Search and Rescue Optimal Planning System (SAROPS). SAROPS can use environmental information products with spatially-varying currents and winds, for the recent past, the present, and a few days into the future. Previously, the USCG had not evaluated the merits of the available environmental products to determine which were best suited for USCG use, and whether they adequately covered USCG areas of responsibility. This report provides a snapshot of environmental information products available at the time of the survey and their characteristics. The study team identified 103 products for further evaluation. The evaluation methodology was based on four areas of product attributes. Recommendations for product use in SAROPS are provided in this report. Summaries describing the nature and quality of each product, and the product coverage for each Coast Guard district, are contained in the appendices.

Book Description
In this book, we study theoretical and practical aspects of computing methods for mathematical modelling of nonlinear systems. A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation;methods for low-rank matrix approximations; hybrid methods based on a combination of iterative procedures and best operator approximation; andmethods for information compression and filtering under condition that a filter model should satisfy restrictions associated with causality and different types of memory.As a result, the book represents a blend of new methods in general computational analysis,and specific, but also generic, techniques for study of systems theory ant its particularbranches, such as optimal filtering and information compression. - Best operator approximation,- Non-Lagrange interpolation,- Generic Karhunen-Loeve transform- Generalised low-rank matrix approximation- Optimal data compression- Optimal nonlinear filtering

Book Description
This book begins with a review of basic results in optimal search for a stationary target. It then develops the theory of optimal search for a moving target, providing algorithms for computing optimal plans and examples of their use. Next it develops methods for computing optimal search plans involving multiple targets and multiple searchers with realistic operational constraints on search movement. These results assume that the target does not react to the search. In the final chapter there is a brief overview of mostly military problems where the target tries to avoid being found as well as rescue or rendezvous problems where the target and the searcher cooperate. Larry Stone wrote his definitive book Theory of Optimal Search in 1975, dealing almost exclusively with the stationary target search problem. Since then the theory has advanced to encompass search for targets that move even as the search proceeds, and computers have developed sufficient capability to employ the improved theory. In this book, Stone joins Royset and Washburn to document and explain this expanded theory of search. The problem of how to search for moving targets arises every day in military, rescue, law enforcement, and border patrol operations.

Book Description
The history of documentary has been one of adaptation and change, as docu-mentarists have harnessed the affordances of emerging technology. In the last decade interactive documentaries (i-docs) have become established as a new field of practice within non-fiction storytelling. Their various incarnations are now a focus at leading film festivals (IDFA DocLab, Tribeca Storyscapes, Sheffield DocFest), major international awards have been won, and they are increasingly the subject of academic study. This anthology looks at the creative practices, purposes and ethics that lie behind these emergent forms. Expert contributions, case studies and interviews with major figures in the field address the production processes that lie behind interactive documentary, as well as the political, cultural and geographic contexts in which they are emerging and the media ecology that supports them. Taking a broad view of interactive documentary as any work which engages with 'the real' by employing digital interactive technology, this volume addresses a range of platforms and environments, from web-docs and virtual reality to mobile media and live performance. It thus explores the challenges that face interactive documentary practitioners and scholars, and proposes new ways of producing and engaging with interactive factual content.
