Assessing Co-ordinated Asian Exchange Rate Regimes

This study assesses alternative Asian exchange rate regimes and finds short- and long-run currency dynamics more conducive to the possibility of introducing a common peg based on a basket of the European euro, the United States dollar and the Japanese yen than the alternative of re-introducing a United States dollar peg exchange rate regime. Exchange rate systems of 3- 4- and 5- Asian currencies are examined and the dynamics in a set of 4 European currencies prior to the introduction of the Euro provides benchmark evidence. The evidence for an Asian basket peg regime is strengthened when, unlike in prior studies, the long-run parameters are estimated while accounting for generalised autoregressive conditional heteroscedasticity effects.Exchange Rate Regimes, Asia, Currency Pegs, Basket Exchange Rates

Effect of type of load on stress analysis of thin-walled ducts

The standard procedure for qualifying the design of duct (pipe) systems in the Space Shuttle Main Engine (SSME) has been fairly well defined. However, since pipe elbows are quite common and important in the SSME duct systems, a clear understanding of the detailed stress profile of the components is necessary for accurate structural and life assessments. This study was initiated to predict the stress profile at/near the tangent point along the cross section of the duct under various types of loads. Also, this study was further extended to understand the stiffening effect on stresses due to pressure at the tangent point. The intention of this study was to identify the importance of selecting proper locations for mounting strain gauges and to utilize the obtained results to anchor dynamic models for accurate structural and life assessments of the SSME ducts under a dynamic environment. The finite element method was utilized in this study
