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

Shutdown management is project management of a special kind: managing the repair, replacement or maintenance of critical systems. Manufacturing and process plants, computer systems, airliners, and many other systems must be regularly closed down or taken out of service for planned maintenance operations. This book provides a complete shutdown project planning guide along with a new, detailed model of excellence and step-by-step project guide. In a critical field, this book shows the maintenance manager or project leader how to get the job done correctly. * Covers all aspects of major maintenance project planning, minimizing downtime and improving maintenance schedules * Covers projects ranging from weekend overhauls through to complete plant rebuilds * With detailed checklists and a new step-by-step project guide
