RISOptimization of Shift Control Trajectories for Step Gear Automatic Transmissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New generation of torque converter automatic transmissions (ATs) include a large number of gears for improved fuel economy and performance. Control requirements for such a transmission become more demanding, which calls ...
Modified Halocline Water over the Laptev Sea Continental Margin: Historical Data Analysis
Publisher: American Meteorological Society
Abstract: istorical hydrographic data (1940s?2010) show a distinct cross-slope difference of the lower halocline water (LHW) over the Laptev Sea continental margins. Over the slope, the LHW is on average warmer and saltier by 0.2°C ...
Eastern Arctic Ocean Diapycnal Heat Fluxes through Large Double-Diffusive Steps
Publisher: American Meteorological Society
Abstract: The diffusive layering (DL) form of double-diffusive convection cools the Atlantic Water (AW) as it circulates around the Arctic Ocean. Large DL steps, with heights of homogeneous layers often greater than 10 m, have been ...
Arctic Ocean Heat Impact on Regional Ice Decay: A Suggested Positive Feedback
Publisher: American Meteorological Society
Abstract: road, long-living, ice-free areas in midwinter northeast of Svalbard between 2011 and 2014 are investigated. The formation of these persistent and reemerging anomalies is linked, hypothetically, with the increased seasonality ...
Intermittent Intense Turbulent Mixing under Ice in the Laptev Sea Continental Shelf
Publisher: American Meteorological Society
Abstract: Vertical mixing in the bottom boundary layer and pycnocline of the Laptev Sea is evaluated from a rapidly sampled 12-h time series of microstructure temperature, conductivity, and shear observations collected under 100% ...
Mooring-Based Observations of Double-Diffusive Staircases over the Laptev Sea Slope
Publisher: American Meteorological Society
Abstract: yearlong time series from mooring-based high-resolution profiles of water temperature and salinity from the Laptev Sea slope (2003?04; 2686-m depth; 78°26?N, 125°37?E) shows six remarkably persistent staircase layers in ...
Analysis of Improving Automatic Transmission Upshift Performance by Using Off-Going Clutch During Inertia Phase
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a detailed numerical and algebraic analysis of potential for improving the step ratio automatic transmission (AT) upshift performance by means of modulating the off-going clutch during the inertia phase. ...
On the Seasonal Cycles Observed at the Continental Slope of the Eastern Eurasian Basin of the Arctic Ocean
Publisher: American Meteorological Society
Abstract: AbstractThe Eurasian Basin (EB) of the Arctic Ocean is subject to substantial seasonality. We here use data collected between 2013 and 2015 from six moorings across the continental slope in the eastern EB and identify three ...
Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean
Publisher: American Meteorological Society
Abstract: A 15-yr duration record of mooring observations from the eastern (>70°E) Eurasian Basin (EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat flux from intermediate-depth (~150–900 ...
