Topological Optimization of Under-Platform Dampers With Moving Morphable Components and Global Optimization Algorithm for Nonlinear Frequency Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To limit the risk of high cycle fatigue, underplatform dampers (UDPs) are traditionally used in aircraft engines to control the level of vibration. Many studies demonstrate the impact of the geometry of the damper on its ...
Enhanced Diffusion of Silver Atoms on the Surface of Nanoparticles at Low Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microstructure development of 35 nm silver nanoparticles during the low temperature sintering was examined in situ as the ambient temperature increased from room temperature up to 450 آ°C using Xray diffraction and ...
Tritium Time Series from Ocean Station P
Publisher: American Meteorological Society
Abstract: We present time series of tritium (3H) concentrations at varying depths in the water column at Ocean Station P(50°N, 145°W) in the northeast Pacific. Measurements started in the fall of 1974, at the time of the GEOSECS ...
On the Efficiency of a Conical Underplatform Damper for Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Underplatform dampers (UPDs) are commonly used in aircraft engines to limit the risk of high-cycle fatigue of turbine blades. The latter is located in a groove between two consecutive blades. The dry friction contact ...
Investigating Variability of Outgoing Longwave Radiation over Peninsular Malaysia Using Wavelet Transform
Publisher: American Meteorological Society
Abstract: he present study analyzes and quantifies the spatial?temporal variability of outgoing longwave radiation (OLR) over peninsular Malaysia using the continuous wavelet transform (CWT) from 2003 to 2010. The goal is to understand ...
On the Influence of Pacific Ocean Temperatures on Atmospheric Carbon Dioxide Concentration at Ocean Weather Station P
Publisher: American Meteorological Society
Abstract: The study presents an analysis of atmospheric CO2 measurements at Ocean Weather Station P (50°N, 145°W) and sea surface temperatures over the North Pacific for the period 1974?78. The results show that during 1976 and 1977 ...
Measurements of Surface Seawater fCO2 from Volunteer Commercial Ships: Techniques and Experiences from Skaugran
Publisher: American Meteorological Society
Abstract: Chemical measurements made in the northern North Pacific from a commercial volunteer observing ship (VOS) program during March 1995?March 1998 are presented. Quasi-continuous measurements of the fugacity of CO2 (fCO2, which ...
The Impact of Hurricane Andrew on the Near-Surface Marine Environment in the Bahamas and the Gulf of Mexico
Publisher: American Meteorological Society
Abstract: Hurricane Andrew was a relatively small but intense hurricane that passed through the Bahamas, across the Florida Peninsula, and across the Gulf of Mexico between 23 and 26 August 1992. The characteristics of this hurricane ...
