  • This textbook is a collection of technical papers that were presented at the 10th International Symposium on Unsteady Aerodynamics, Aeroacoustics, and Aeroelasticity of Turbomachines held September 8-11, 2003 at Duke University in Durham, North Carolina. The papers represent the latest in state of the art research in the areas of aeroacoustics, aerothermodynamics, computational methods, experimental testing related to flow instabilities, flutter, forced response, multistage, and rotor-stator effects for turbomachinery....

  • The 1980s and 1990s have been critical periods for Thailand’s development. After an initial period of instability in the early 1980s, Thailand’s economy expanded at an average pace of 9 percent p.a. during 1987–96, while the number of households below the poverty line dropped from 32.6 percent in 1988 to 16.3 percent in 1996. During this period, Thailand’s economy also underwent deep structural changes, including the liberalization of its financial sector and the integration of its economy with global financial and product markets.

  • Many classical integrable systems (like the Euler, Lagrange and Kowalewski tops or the Neumann system) as well as finite dimensional reductions of many integrable PDEs share the property of being algebraically completely integrable systems4. This means that they are completely integrable Hamiltonian systems in the usual sense and, moreover, their complexified invariant tori are open subsets of complex Abelian tori on which the complexified flow is linear. To such systems the powerful algebro-geometrical techniques may be applied...

  • For many manufacturing enterprises, assembly is an important portion of the final costs. Effectiveness was traditionally hunted for by reducing complex schedules into unit tasks (scientific work organization) and by enabling sequential assembly lines (vertical flow-shop). The approach leads to the highest productivity, and it is prised for mass production. Flow-lines and fixed schedules, however, require amortisation plans based on steady programmes on duty horizons corresponding to product volumes exceeding some minimal threshold.
