A Variational Method for Analyzing Vortex Flows in Radar-Scanned Tornadic Mesocyclones. Part I: Formulations and Theoretical Considerations
Publisher: American Meteorological Society
Constructing Oscillating Function-Based Covariance Matrix to Allow Negative Correlations in Gaussian Random Field Models for Uncertainty Quantification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gaussian random field has been widely applied to quantify high-dimensional uncertainties in the spatial or temporal domain. A common practice in Gaussian random field modeling is to use the exponential function to represent ...
Atmospheric Responses to Kuroshio SST Front in the East China Sea under Different Prevailing Winds in Winter and Spring
Publisher: American Meteorological Society
Abstract: tmospheric responses to the Kuroshio SST front in the East China Sea under different prevailing winds are examined using high-resolution observations and numerical modeling. Satellite data reveal a significant in-phase ...
Experimental Research on Residual Clamping Force of Friction High-Strength Bolt after Corrosion Loss Simulated by Wire Cutting
Publisher: American Society of Civil Engineers
Abstract: Clamping force is crucial for resisting slip loads in friction-type high-strength bolted (FHSB) connections, and following corrosion, it diminishes due to sectional reduction of the nuts and/or bolt heads. Evaluating ...
Study on the Iced Quad Bundle Transmission Lines Incorporated With Viscoelastic Antigalloping Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The viscoelastic damper is one of the most promising devices for vibration mitigation. In order to reduce dynamic responses of iced transmission lines due to strong wind, a new kind of viscoelastic antigalloping device ...
Microstructures and Mechanical Properties of Dimethyl Sulfoxide Pretreated Graphene Modified Asphalt
Publisher: ASCE
Abstract: The rutting and cracking distresses of asphalt pavement severely affect its service life. Enhancing the visco-toughness and mechanical properties of asphalt by using graphene may improve the durability of asphalt pavement. ...
One-Dimensional Compression Fractal Theory and Experimental Verification of Coarse-Grained Soil
Publisher: American Society of Civil Engineers
Abstract: Coarse-grained soil particles are suspectible to breakage under high-stress conditions, with particle breakage being the main reason for the compression of samples. The compression coefficient λ in the e–log σ′ curve is ...
Robotic Time Varying Force Tracking in Position Based Impedance Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a unified control framework for both setpoint and timevarying force control of robot manipulator by introducing an improved positionbased impedance control (IPBIC). In order to essentially achieve ...
The Existence and Stability of Steady Circulations in a Conditionally Symmetrically Unstable Basic Flow
Publisher: American Meteorological Society
Abstract: By treating the latent heating as an energy source which is implicitly related to the motion field, the existence of steady nonlinear circulations in a flow susceptible to Conditionally Symmetric Instability (CSI) is ...
