RISEvolutionary Algorithm-Based Error Parameterization Methods for Data Assimilation
Publisher: American Meteorological Society
Abstract: he methods of parameterizing model errors have a substantial effect on the accuracy of ensemble data assimilation. After a review of the current error-handling methods, a new blending error parameterization method was ...
Determination of Folias Factor for Failure Pressure of Corroded Pipeline
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Corrosion assessment and burst pressure prediction of line pipes with corrosion defects are essential for the integrity assessment of steel transmission pipelines. The failure assessment methods proposed in codes or handbooks ...
Theoretical and Experimental Study and Design Method of Blade Height of a Rotational-Flow Suction Unit in a Wall-Climbing Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A wall-climbing robot that uses a rotational-flow suction unit to be non-contact-absorbed onto walls can climb rough walls and overstep obstacles. In the rotational-flow suction unit, the air driven by the blades rotates ...
Numerical Investigation of Ship Waves and Associated Hydrodynamics Over a Sloping Bed With a Non-Hydrostatic Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ship waves and related hydrodynamics over a sloping bed are investigated numerically in this paper, and we aim to clarify the characteristics of ship wave deformation and its hydrodynamic effects. Laboratory experiments ...
An Improved Decoupled Finite Element Analysis Method of Ultra-Large Offshore Wind Turbine Subjected to Combined Wind–Wave Actions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Owing to the simplification of the wind turbine, it is difficult to accurately simulate the interaction between the rotor system and the supporting structure using the decoupling finite element method. Therefore, when using ...

Empirical Analysis of Factors Influencing Potential Demand of Customized Buses in Shanghai, China
Publisher: American Society of Civil Engineers
Abstract: The customized bus (CB) is an emerging commute mode in China, and it is operated flexibly with schedules arranged based on online reservations. However, a CB can only be operated with sufficient travel demand. This paper ...
Impacts of Ship Waves on Bed Morphology of a Trapezoidal Cross-Sectional Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ship waves could alter the hydrodynamic field and play an important role for sediment movement and morphological changes, especially in shallow water regions of inland waterways. However, the response of riverbed morphology ...
Topology Optimization Design of Scramjet Structures With Forced Convective Heat Transfer on Unstructured Meshes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A topology optimization strategy with coupled fluid–solid interaction was proposed to maximize the cooling efficiency of a kind of structure applied for scramjets. The Galerkin finite element method (FEM) is used to solve ...
An Alternative Bias Correction Scheme for CrIS Data Assimilation in a Regional Model
Publisher: American Meteorological Society
Abstract: Bias correction (BC) is a crucial step for satellite radiance data assimilation (DA). In this study, the traditional airmass BC scheme in the National Centers for Environmental Prediction (NCEP) Gridpoint Statistical ...
