Boundary Bias Correction Using Weighting Method in Presence of Nonresponse in Two-Stage Cluster Sampling

open access: yesJournal of Probability and Statistics, 2019
Kernel density estimators due to boundary effects are often not consistent when estimating a density near a finite endpoint of the support of the density to be estimated.

Effects of Initial-Boundary Conditions on the Simulation of a Supercell Storm

open access: yesGaoyuan qixiang, 2023
To understand the impacts and mechanisms of initial-boundary conditions on the simulation of meso- and micro-scale weather system, a supercell storm episode occurred in the Capital Airport on August 9, 2021.This study simulated by WRF (version 4.3) model

Advanced Statistical Learning: Limit Theorems for Nonparametric Conditional U-Statistics Smoothed by Asymmetric Kernels Under Missing-at-Random Sampling

open access: yesMathematics
This paper develops a boundary-sensitive asymptotic theory for nonparametric conditional U-statistics smoothed by support-adapted asymmetric kernels when the response variable is subject to Missing-at-Random observation.

Gamma Kernel Estimators for Density and Hazard Rate of Right-Censored Data

open access: yesJournal of Probability and Statistics, 2011
The nonparametric estimation for the density and hazard rate functions for right-censored data using the kernel smoothing techniques is considered. The “classical” fixed symmetric kernel type estimator of these functions performs well in the interior ...

Evaluation of Southern Ocean cloud in the HadGEM3 general circulation model and MERRA-2 reanalysis using ship-based observations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Southern Ocean (SO) shortwave (SW) radiation biases are a common problem in contemporary general circulation models (GCMs), with most models exhibiting a tendency to absorb too much incoming SW radiation. These biases have been attributed to deficiencies

Evaluation of the Antarctic Boundary Layer Thermodynamic Structure in MERRA2 Using Dropsonde Observations from the Concordiasi Campaign

open access: yesEarth and Space Science, 2019
Recent high‐resolution dropsonde observations from the 2010 Concordiasi field campaign in austral spring season show that surface‐based inversions (SBIs) over Antarctica are frequently eroded, with well‐mixed boundary layers occurring 33% and 18% of the ...

Robust Wavelet Estimation to Eliminate Simultaneously the Effects of Boundary Problems, Outliers, and Correlated Noise

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
Classical wavelet thresholding methods suffer from boundary problems caused by the application of the wavelet transformations to a finite signal. As a result, large bias at the edges and artificial wiggles occur when the classical boundary assumptions ...

Confirmation Bias: A Boundary Condition for Dynamic Managerial Capabilities in the Context of Strategic Change [PDF]

open access: yes, 2021
In today’s fast-changing environment, achieving sustainable competitive advantage constitutes a major challenge for managers. Research suggests that dynamic managerial capabilities (DMCs) enable managers to overcome this challenge by building, integrating, and reconfiguring organizational resources and competences. While prior studies in this tradition

Adaptive Fault-Tolerant Boundary Control of UAV Formations with Reliable Interior Sensing via a PDE Continuum Model

open access: yesAerospace
An adaptive fault-tolerant boundary controller is developed for large UAV leader–follower formations affected by leader actuator faults. The formation-error dynamics are modeled by a one-dimensional parabolic PDE with reaction and convection terms, with ...
