Large-Scale Optimization: Problems and Methods
ISBN: 9780792368175 / Angielski / Twarda / 2001 / 312 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Decomposition methods aim to reduce large-scale problems to simpler problems. This monograph presents selected aspects of the dimension-reduction problem. Exact and approximate aggregations of multidimensional systems are developed and from a known model of input-output balance, aggregation methods are categorized. The issues of loss of accuracy, recovery of original variables (disaggregation), and compatibility conditions are analyzed in detail. The method of iterative aggregation in large-scale problems is studied. For fixed weights, successively simpler aggregated problems are solved and...

Hierarchical Optimization and Mathematical Physics
ISBN: 9781461371120 / Angielski / Miękka / 2013 / 310 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book should be considered as an introduction to a special dass of hierarchical systems of optimal control, where subsystems are described by partial differential equations of various types. Optimization is carried out by means of a two-level scheme, where the center optimizes coordination for the upper level and subsystems find the optimal solutions for independent local problems. The main algorithm is a method of iterative aggregation. The coordinator solves the problern with macrovariables, whose number is less than the number of initial variables. This problern is often very simple....

Aggregation in Large-Scale Optimization
ISBN: 9781461348122 / Angielski / Miękka / 2013 / 291 str. Termin realizacji zamówienia: ok. 20 dni roboczych. When analyzing systems with a large number of parameters, the dimen- sion of the original system may present insurmountable difficulties for the analysis. It may then be convenient to reformulate the original system in terms of substantially fewer aggregated variables, or macrovariables. In other words, an original system with an n-dimensional vector of states is reformulated as a system with a vector of dimension much less than n. The aggregated variables are either readily defined and processed, or the aggregated system may be considered as an approximate model for the orig- inal system. In...

Minimax Under Transportation Constrains
ISBN: 9781461368182 / Angielski / Miękka / 2013 / 310 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Transportation problems belong to the domains mathematical program- ming and operations research. Transportation models are widely applied in various fields. Numerous concrete problems (for example, assignment and distribution problems, maximum-flow problem, etc. ) are formulated as trans- portation problems. Some efficient methods have been developed for solving transportation problems of various types. This monograph is devoted to transportation problems with minimax cri- teria. The classical (linear) transportation problem was posed several decades ago. In this problem, supply and demand...

Nonlinear Diffusion For Noise Elimination
ISBN: 9783848442904 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A class of nonlinear diffusion equations with a power-law dependence of the coefficient on the gradient is considered. Such equations are used in the problem of suppressing image noise. The mathematical properties of this class of equations are considered. One of them ensures protection of image edges. Computational results on noise elimination in real-life images are presented. The book is intended for scientists and engineers working in mathematical physics, differential equations, and image processing and for college and university professors and postgraduate and graduate students.

Control of Fluid-Containing Rotating Rigid Bodies
ISBN: 9781138000216 / Angielski / Twarda / 2013 / 160 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. This book is devoted to the study of the dynamics of rotating bodies with cavities containing liquid. Two basic classes of motions are analyzed: rotation and libration. Cases of complete and partial filling of cavities with ideal liquid and complete filling with viscous liquid are treated. The volume presents a method for obtaining relations between angular velocities perpendicular to main rotation and external force momentums, which are treated as control. The developed models and methods of solving dynamical problems as well as numerical methods for solving problems of optimal...This book is devoted to the study of the dynamics of rotating bodies with cavities containing liquid.
