Transonic flow occurs around moving objects as they approach and cross the sound barrier. Serious problems can occur at this point, such as shock-induced flow separation which can cause the aircraft to spin out of control. Another important practical problem is the achievement of higher aerodynamic performance of aircraft at cruise conditions, which leads to considerable fuel savings. The success in application of numerical methods for simulation of transonic flow and aircraft design depends on developments in the underlying mathematical theory. This book presents a breakthrough in the solvability analysis of boundary value problems, which makes it possible to establish convergence of finite element approximations for shock-free flow and to provide a framework for putting the existing numerical methods on a more sound basis. Also, physical aspects concerned with patterns of formation and propagation of weak shock waves are analysed. This contributes to the understanding of the extreme sensitivity of transonic flow to perturbation of freestream conditions. The developed theoretical knowledge base yields promising concepts of the airfoil design and active flow control by airfoil/wing shape modifications or suction/blowing through a perforated surface. Boundary Value Problems for Transonic Flow * Focuses on Computational Fluid Dynamics. * Addresses practical problems, such as airfoil design and flow control. * Presents developments made in the last two decades. In essence this is a much needed monograph for researchers and engineers in applied mathematics and numerical analysis applied to aerodynamics and for algorithm developers in Computational Fluid Dynamics in the aircraft industry. It gives design engineers the underlying mathematical theory necessary for developing new concepts for airfoil/wing design and flow control.

In order to develop production and expand markets for all interested in handling financial resources. Own funds are limited because actual borrowed funds of credit institutions. Loan is secured by collateral, for which execution is levied for improper fulfillment of financial obligations. When activated, deposit procedures arises business process by which the performance of collateral, encumbered with outstanding financial obligation, it becomes a catalyst for dispersion of its value among the involved credit institutions affiliated to it the same structures, and the borrower, the owner of the collateral, forced to pay for their services. Registry of collateral individual credit institution is the value of having a monetary value, or more precisely register the debt, the return of the collateral is provided, during the implementation procedures of the collateral is an extremely topical issue of cost. Affiliated bank structure use a "ready" for implementation of the collateral as a financial instrument whose value is dynamic in time.

The aim of the article is to perform an economic and legal analysis of the financial claims of the credit institution to the borrower through the implementation of the acquired using borrowed funds vehicle that is owned by the borrower and burdened the right of pledge in favor of the bank. And also to identify factors influencing the effect of the financial cost of spraying alienated collateral, including affiliated bank structures, be associated with this process.
