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

ABSTRACT: Licensing a commercial nuclear reactor core involves a stringent amount of calculations that demonstrate the capability of safe reactor shutdown in the instance of an emergency transient event. In a boiling water nuclear reactor the control blades and standby liquid control system are the two independent redundant safety systems utilized for shutting down the reactor. In past fuel designs lower power cores with smaller cycle lengths resulting from lower core average enrichment caused shutdown by the control blades to be the most limiting strategy of the two modes for reactor shutdown. This led to a lesser focus on fuel design strategies for standby liquid control system margin (SLCS). Advanced modern core designs involve higher powers and increased cycle lengths resulting from higher core average enrichments, therefore causing SLCS to now become a more significant shutdown parameter.
