Abstract: Torsional resonance in coupled rotating systems such as multiunit turbine-gear-compressor trains is sometimes a serious problem and several shaft failures have been reported. Often it is desirable ...

Abstract: Several instances of gear, coupling, or turbine-bucket failures in systems in which the compressors were subjected to extensive periods of heavy surge suggested the possibility that the transient ...

Abstract: Calibration of shipmounted acoustic Doppler profiles by a series of 90° turns during periods of GPS navigation provides estimates of misalignment angle φ and scaling factor A with standard deviations less than 0.2° and ...

Abstract: the 50 km spacing, and can be modeled by forcing the Pollard and Millard (1970) model with the local wind. Analysis of the inertial oscillations generated by a well-developed traveling depression suggests that their amplitudes can fall to zero within a...

Abstract: Inverse analysis (Wunsch, 1978) has been applied to two 10-day surveys of an area 15 km consisting of nearly 100 CTD stations, in order to determine the velocity field with a horizontal resolution of 45 km. Reference levels ...

Abstract: Our climate is changing, and we need to know why. This work aims to assess potential causes, such as freshwater sources of atmospheric CO2, not previously considered. The rate freshwater bacteria respired dissolved organic ...

Abstract: Some results of recent work on low-speed cascade tunnels are described. Preliminary investigations, directed toward the analysis and improvement of the airflow and testing techniques, revealed ...
