Investigation of a Design Modification for Double Helical Gears Reducing Vibration and Noise
tooth profile modification tooth longitudinal modification double helical gears loaded transmission error
2011/9/9
To reduce vibration and noise and increase transmission efficiency, a three segment method for modifying the pinion profile was proposed. Cutter surface equations were deduced by changing the shape of...
The Effects of Bias Error and System Noise on Parameters Computed from C, T, P and V Profiles
Bias Error V Profiles System Noise
2009/2/11
The development of high-resolution profiling instruments has made possible the computation of quantities such as the stability parameter N2 and the Richardson number Ri over scales of less than a mete...
Influence of Bubbles on Ambient Noise in the Ocean at High Wind Speeds
Bubbles Ambient Noise High Wind Speeds
2009/1/21
Observations of ambient noise in the ocean at high wind speeds reveal significant departures in spectral shape from previously reported values at lower wind speeds. The observations were made in open ...
Correlations between Ambient Noise and the Ocean Surface Wave Field
Ambient Noise Ocean Surface Wave Field
2008/12/11
Measurements of the ambient noise spectrum level N with simultaneous, coincident wind and wave measurements were made from RP FLIP in fall 1991. The measurements were designed to investigate the corre...
Noise-Induced Transitions in a Simplified Model of the Thermohaline Circulation
Noise-Induced Transitions Simplified Model Thermohaline Circulation
2008/7/2
A simplified box ocean model for the North Atlantic is used to study the influence of multiplicative short-term climate variability on the stability and long-term dynamics of the North Atlantic thermo...
Noise Effects on Wave-Generated Transport Induced by Ideal Waves
Noise Effects Wave-Generated Transport Induced Ideal Waves
2008/6/13
The authors consider the transport velocity in boundary layer flows driven by either noisy monochromatic progressive or standing waves. The central issue addressed here is whether such flows are capab...
Stabilization of Climate Regimes by Noise in a Simple Model of the Thermohaline Circulation
Climate Regimes Noise Thermohaline Circulation
2008/6/11
Salinity dynamics in a simple two-box model of the thermohaline circulation (THC) is considered. The model parameterizes fluctuating eddy transport and buoyancy forcing by two independent stochastic p...
