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...
Upper Layer Modification at Ocean Station Papa：Observations and Simulation
Upper Layer Modification Ocean Station Papa
2009/4/2
Time-series observations of the upper mixed layer of the ocean are presented for a six-week period at Ocean Station Papa in the northeast Pacific Ocean. These observations indicate the rate and extent...
Topographic Modification of the Florida Current by Little Bahama and Great Bahama Banks
Subtropical Atlantic Climate Studies Bahama Bahama Banks Florida Current
2009/1/8
The effect of local topography in modifying the structure and variability of the Florida Current is examined using shipboard acoustic Doppler and PEGASUS acoustic current profiler data. PEGASUS absolu...
Modification of the Gulf Stream through Strong Air–Sea Interactions in Winter：Observations and Numerical Simulations
Gulf Stream Numerical Simulations Air–Sea Interactions
2008/12/11
The greatest fluxes of heat and moisture from the ocean to the atmosphere occur off the east coast of North America during winter when the Gulf Stream is vigorously cooled by strong cold air outbreaks...
Distribution and Modification of North Pacific Intermediate Water in the Kuroshio-Oyashio Interfrontal Zone
North Pacific Intermediate Water multiship CTD survey Kuroshio-Oyash interfrontal zone
2008/12/9
A multiship CTD survey was conducted in the Kuroshio-Oyash interfrontal zone in the area of 30°–41°N, 140°E–180° from May to June 1992 to examine the distribution, modification process, and formation ...
The Modification of Long Planetary Waves by Homogeneous Potential Vorticity Layers
Long Planetary Waves Homogeneous Potential Vorticity Layers
2008/7/8
A mechanism by which long planetary waves in the ocean may propagate significantly faster than the classical long baroclinic Rossby waves is investigated. The mechanism depends on the poleward thicken...
A Modification of the Garrett–Munk Internal Wave Spectrum
Modification Garrett–Munk Internal Wave Spectrum
2008/6/23
The Garrett–Munk (GM) spectrum continues to be a useful description of the oceanic internal wave field. However, there are several inconsistencies and ambiguities that make it difficult to use in comp...
