RISShort-Term Phenological Predictions of Vegetation Abundance Using Multivariate Adaptive Regression Splines in the Upper Colorado River Basin
Publisher: American Meteorological Society
Abstract: he accurate prediction of plant phenology is of significant importance for more sustainable and effective land management. This research develops a framework of phenological modeling to estimate vegetation abundance ...
Analytical Model to Estimate the Drag Forces for Microhole Coiled Tubing Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microhole coiled tubing drilling is a new technology that provides many added advantages but at the same time poses numerous operational challenges. This manifests itself in a number of ways, all of which adversely affect ...
Sensitivity Test of POP System Matrices—An Application of Spectral Portrait of a Nonsymmetric Matrix
Publisher: American Meteorological Society
Abstract: By using the POP (principal oscillation pattern) system matrices as examples, this study introduces to the meteorological community the concept and application of spectral portrait (or pseudospectra) of a nonsymmetric ...
Is Climate Variability over the North Pacific a Linear Response to ENSO?
Publisher: American Meteorological Society
Abstract: Indices of the dominant spatial patterns of wintertime Northern Hemisphere 500-mb height and North Pacific sea surface temperature are strongly correlated with one another on interannual and interdecadal timescales, and ...
Interpretation of Interdecadal Trends in Northern Hemisphere Surface Air Temperature
Publisher: American Meteorological Society
Abstract: Monthly Mean time series of 1) surface air temperature anomalies averaged over the Northern Hemisphere based on data from land stations, 2) sea surface temperature anomalies averaged over the Northern Hemisphere oceans, ...
Light-Weight Design of Five-Degree-of-Freedom Hybrid Robot for Assembling in the Cabin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interior assembling inside the cabin of an aircraft requires assembling robot to be light-weight and able to carry heavy payload. This paper proposed a hybrid robot and carried out its optimal design and experiments. The ...
Research on Friction and Wear Behaviors of Different Solid Lubricant Coatings on Aluminum-Based Piston Skirts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stringent requirements in emissions drive the application of low-carbon fuel engines, which result in prominent friction and lubrication problems in the cylinder. Solid coating technology is an effective way to enhance the ...
On the Model-Free Compensation of Coulomb Friction in the Absence of the Velocity Measurement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper demonstrates that the Coulomb friction, the most difficult part of friction to be compensated because of its discontinuity with respect to the velocity, can be precisely compensated without either its mathematical ...
Role of Low Clouds in Summertime Atmosphere–Ocean Interactions over the North Pacific
Publisher: American Meteorological Society
Abstract: The summer-to-summer variability of the areal extent of marine stratiform cloudiness (MSC; stratus, stratocumulus, and fog) over the North Pacific is examined for the period of record 1952?92 using a dataset based on surface ...
Seasonality of Large-Scale Atmosphere–Ocean Interaction over the North Pacific
Publisher: American Meteorological Society
Abstract: This paper attempts to resolve a long-standing paradox concerning the season-to-season memory of sea surface temperature anomalies (SSTAs) over the North Pacific. Summertime SSTAs are confined to a shallow mixed layer that ...
