RISFilling N Sided Holes With Trimmed B Spline Surfaces Based on Energy Minimization Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using a trimmed rectangular BSpline surface to fill an nsided hole is a much desired operation in computer aided design (CAD), but few papers have addressed this issue. Based on an energyminimization or variational BSpline ...
Discussion of “Fabric and Effective Stress Distribution in Internally Unstable Soils” by T. Shire, C. O’Sullivan, K. J. Hanley, and R. J. Fannin
Publisher: American Society of Civil Engineers
GHG Mitigation Policies and Land Use Interactions
Publisher: American Society of Civil Engineers
Abstract: Greenhouse gas (GHG) emissions are widely acknowledged to be responsible for much of the global warming in the past century. Since the burning of fossil-based fuels is an important source of GHGs, the policies on GHG ...
Type Curves Analysis for Asymmetrically Fractured Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new constant rate solution for asymmetrically fractured wells was proposed to analyze the effect of fracture asymmetry on type curves. Calculative results showed that for a small wellbore storage coefficient ...
Impacts of the Diurnal Radiation Cycle on the Formation, Intensity, and Structure of Hurricane Edouard (2014)
Publisher: American Meteorological Society
Abstract: his work examines the impacts of the diurnally varying radiation cycle on the formation, intensity, structure, and track of Hurricane Edouard (2014) at different stages of its life cycle through convection-permitting ...
Robust Ensemble Filtering and Its Relation to Covariance Inflation in the Ensemble Kalman Filter
Publisher: American Meteorological Society
Abstract: robust ensemble filtering scheme based on the H∞ filtering theory is proposed. The optimal H∞ filter is derived by minimizing the supremum (or maximum) of a predefined cost function, a criterion different from the minimum ...
Time Domain Analysis on the Dynamic Response of a Flexible Floating Structure to Waves
Publisher: American Society of Civil Engineers
Abstract: A time-domain numerical method is developed to analyze the hydroelastic responses of flexible floating structures to waves; in which, the boundary element method is applied to evaluate the fluid motion and the finite-element ...
Ensemble Kalman Filtering with Residual Nudging: An Extension to State Estimation Problems with Nonlinear Observation Operators
Publisher: American Meteorological Society
Abstract: he ensemble Kalman filter (EnKF) is an efficient algorithm for many data assimilation problems. In certain circumstances, however, divergence of the EnKF might be spotted. In previous studies, the authors proposed an ...
Understanding Model-Based Probable Maximum Precipitation Estimation as a Function of Location and Season from Atmospheric Reanalysis
Publisher: American Meteorological Society
Abstract: AbstractExtreme precipitation events bring huge societal and economic loss around the world every year, and they have undergone spatially heterogeneous changes in the past half-century. They are fundamental to probable ...
Covariance Inflation in the Ensemble Kalman Filter: A Residual Nudging Perspective and Some Implications
Publisher: American Meteorological Society
Abstract: his article examines the influence of covariance inflation on the distance between the measured observation and the simulated (or predicted) observation with respect to the state estimate. In order for the aforementioned ...
