RISClimate Change, High-Temperature Stress, Rice Productivity, and Water Use in Eastern China: A New Superensemble-Based Probabilistic Projection
Publisher: American Meteorological Society
Abstract: he impact of climate change on rice productivity in China remains highly uncertain because of uncertainties from climate change scenarios, parameterizations of biophysical processes, and extreme temperature stress in crop ...
Dynamic Response of Terrestrial Hydrological Cycles and Plant Water Stress to Climate Change in China
Publisher: American Meteorological Society
Abstract: ising atmospheric CO2 concentration CO2 and climate change are expected to have a major effect on terrestrial ecosystem hydrological cycles and plant water stress in the coming decades. The present study investigates the ...
A Numerical Study on the Combustion and Emissions Characteristics of a Heavy Duty Natural Gas/Diesel RCCI Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to energy shortages and environmental issues, the application of reactivity controlled compression ignition (RCCI) combustion in internal combustion engines has received extensive attention. Through the verification ...
Residual Stress Calculation of Hydraulic Autofrettage Thick-Walled Tube Based on a Revised Kinematic Hardening Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current theoretical calculation methods for autofrettage of thick-walled tube do not adequately consider the change in the stress–strain relationship of the material with the maximum loading strain. This deficiency has ...
Study on a Vapor Feed Air Breathing Direct Methanol Fuel Cell Assisted by a Catalytic Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Feeding vaporized methanol to the direct methanol fuel cell (DMFC) helps reduce the effects of methanol crossover (MCO) and facilitates the use of highconcentration or neat methanol so as to enhance the energy density of ...
Effects of Wobbe Index on the Combustion and Emission Characteristics of a Natural Gas/Diesel RCCI Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to energy shortage and environmental problems, the application of natural gas in internal combustion engine has attracted extensive attention. Therefore, diesel pilot ignition natural gas engine is a promising technology. ...
Design of Large Single-Mobility Surface-Deployable Mechanism Using Irregularly Shaped Triangular Prismoid Modules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the design methodology for a single-mobility, large surface-deployable mechanism using irregularly shaped triangular prismoid units. First, we demonstrate that the spherical shell, as the deployed profile ...
Mitigation of Stick-Slip Vibrations in Drilling Systems With Tuned Top Boundary Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aiming at preventing stick-slip oscillations in drilling systems for oil and gas explorations, a reduced-order model is proposed to capture the nonlinear torsional dynamics of drilling operations. In this model, the drill ...
Grand Challenges in Understanding the Interplay of Climate and Land Changes
Publisher: American Meteorological Society
Abstract: alf of Earth?s land surface has been altered by human activities, creating various consequences on the climate and weather systems at local to global scales, which in turn affect a myriad of land surface processes and the ...
