Taschenbuch. Condizione: Neu. Neuware - This book deals with density, temperature, velocity and concentration fluctuations in fluids and fluid mixtures. The book first reviews thermal fluctuations in equilibrium fluids on the basis of fluctuating hydrodynamics. It then shows how the method of fluctuating hydrodynamics can be extended to deal with hydrodynamic fluctuations when the system is in a stationary nonequilibrium state. In contrast to equilibrium fluids where the fluctuations are generally short ranged unless the system is close to a critical point, fluctuations in nonequilibrium fluids are always long-ranged encompassing the entire system. The book provides the first comprehensive treatment of fluctuations in fluids and fluid mixtures brought out of equilibrium by the imposition of a temperature and concentration gradient but that are still in a macroscopically quiescent state. By incorporating appropriate boundary conditions in the case of fluid layers, it is shown how fluctuating hydrodynamics affects the fluctuations close to the onset of convection. Experimental techniques of light scattering and shadowgraphy for measuring nonequilibrium fluctuations are elucidated and the experimental results thus far reported in the literature are reviewed. Systematic exposition of fluctuating hydrodynamics and its applications First book on nonequilibrium fluctuations in fluids Fluctuating Boussinesq equations and nonequilibrium fluids Fluid layers and onset of convection Rayleigh scattering and Brillouin scattering in fluids Shadowgraph technique for measuring fluctuations Fluctuations near hydrodynamic instabilities.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Written for managers and professionals in business and industry, this book helps the reader in: \* Understanding what is and is not IFRS \* Learning the complexities of IFRS implementation\* Appreciating the contribution of IFRS to corporate governance The changeover from the mosaic of different heterogeneous national accounting standards to the International Financial Reporting Standards has not been easy. For many companies IFRS, and most particularly the concept of fair value in IAS 39, has amounted to a phase shift - which is prerequisite to achieving compliant financial reporting. The research conducted by Dr. Chorafas for this book, documented that the process of meeting IFRS requirements presents opportunities and challenges to all enterprises. As many companies have found out, abandoning the classical accruals accounting for marking-to-market their transactions and portfolio positions, has not been easy. The conversion process has affected several functions within the organization including balance sheets, P&L statements, auditing, risk control, information systems, and management accounting. This book is in made up of four parts: \* Part One focuses on business competition, standards boards, corporate accounting, and IAS 39 \* The theme of Part Two, is the implementation of IFRS, exemplified through case studies on task forces and practical applications \* Part Three brings together IFRS and management accounting requirements, with emphasis on fair value. \* Part Four addresses itself to the contribution IFRS can make to better corporate governance, and to rebuilding the balance sheet The book has many case studies based on actual experiences. These range from the implementation of IFRS directives such as hedge accounting, to developing practices of real-time balance sheets; the help provided by sophisticated accounting solutions help in stress testing; and a comprehensive definition of the role of the audit committee. 412 pp. Englisch.
