Book Description :

"Following a period of protracted turbulence, regulators on both sides of the Atlantic face the challenge of re-evaluating prudential standards in the midst of implementing the new so-called 'Basel II' rules, issued by the Basel Committee on Banking Supervision. Indeed, the 2007 subprime lending crisis and other scandals have cast doubt on the credibility of banks' internal governance and risk assessment and management systems and the role of credit rating agencies in externally assessing the risk of complex structured products. Equally, the capacity of regulators to monitor the risky, multifaceted activities of large cross-border institutions has been subjected to immense stress." "In addressing these issues, this CEPS Task Force report supports a regulatory paradigm shift, which resets the incentives to establish an integrated risk-assessment, -management and -governance culture at an institution-wide level. Towards this end, it stresses the need to strengthen the roles of pillars 2 and 3 (supervisory review and market discipline) and to avoid relying solely on the outcome of easily manipulated, excessively sophisticated internal models to determine capital requirements and a supervisory 'box-ticking' approach. The report also examines the potential consequences of the new rules on the basis of early quantitative impact studies and warns of undesirable impacts under adverse market conditions. Finally, it examines the progress achieved in implementing Basel II in Europe and in the US and raises questions about global regulatory consistency and convergence."--BOOK JACKET.

Book Description :

Basel II, the new risk-based capital framework based on an international accord, is being adopted by individual countries. It includes standardized and advanced approaches to estimating capital requirements. In the U.S., bank regulators have finalized an advanced approach rule that will be required for some of the largest, most internationally active banks and proposed an optional standardized approach rule for non-core banks that will also have the option to remain on existing capital rules. This report examines: (1) the markets in which banks compete; (2) how new capital rules address U.S. banks' competitive concerns; and (3) actions regulators are taking to address competitive and other potential negative effects during implementation.

Language : En, Es, Fr & De

DOWNLOAD

Book Description :

This book gives a mathematical insight--including intermediate derivation steps--into engineering physics and turbulence modeling related to an anisotropic modification to the Boussinesq hypothesis (deformation theory) coupled with the similarity theory of velocity fluctuations. Through mathematical derivations and their explanations, the reader will be able to understand new theoretical concepts quickly, including how to put a new hypothesis on the anisotropic Reynolds stress tensor into engineering practice. The anisotropic modification to the eddy viscosity hypothesis is in the center of research interest, however, the unification of the deformation theory and the anisotropic similarity theory of turbulent velocity fluctuations is still missing from the literature. This book brings a mathematically challenging subject closer to graduate students and researchers who are developing the next generation of anisotropic turbulence models. Indispensable for graduate students, researchers and scientists in fluid mechanics and mechanical engineering.

Book Description :

Turbulent combustion sits at the interface of two important nonlinear, multiscale phenomena: chemistry and turbulence. Its study is extremely timely in view of the need to develop new combustion technologies in order to address challenges associated with climate change, energy source uncertainty, and air pollution. Despite the fact that modeling of turbulent combustion is a subject that has been researched for a number of years, its complexity implies that key issues are still eluding, and a theoretical description that is accurate enough to make turbulent combustion models rigorous and quantitative for industrial use is still lacking. In this book, prominent experts review most of the available approaches in modeling turbulent combustion, with particular focus on the exploding increase in computational resources that has allowed the simulation of increasingly detailed phenomena. The relevant algorithms are presented, the theoretical methods are explained, and various application examples are given. The book is intended for a relatively broad audience, including seasoned researchers and graduate students in engineering, applied mathematics and computational science, engine designers and computational fluid dynamics (CFD) practitioners, scientists at funding agencies, and anyone wishing to understand the state-of-the-art and the future directions of this scientifically challenging and practically important field.
