GNAQPMS-Hg v1.0, a global nested atmospheric mercury transport model: model description, evaluation and application to trans-boundary transport of Chinese anthropogenic emissions [PDF]

open access: yesGeoscientific Model Development, 2015
Atmospheric mercury (Hg) is a toxic pollutant and can be transported over the whole globe due to its long lifetime in the atmosphere. For the purpose of assessing Hg hemispheric transport and better characterizing regional Hg pollution, a global nested ...

UNBALANCED NESTED COMPONENT ERROR MODEL FOR ESTIMATING PEST DAMAGE FUNCTIONS [PDF]

open access: yes, 2017
A recently developed nested error component model for unbalanced panel data is used to estimate insect damage functions. The model estimates the separate random effects for location and year on the variability of yield loss and has smaller standard ...

On testing random effects in the nested-error regression model

open access: yesCommunications in Statistics - Simulation and Computation, 2017
We derive an exact F-test for random effects in the nested-error regression model. The derivation utilizes a matrix decomposition that offers a transformation of the response vector into two indepe...

Small area estimation using nested-error models and auxiliary data [PDF]

open access: yes, 1983
A prediction approach to small area estimation is presented. The procedure uses survey and auxiliary data and is based on the assumption of a nested-error model.

Partitioning Error Spaces in Linear Models (Error Contrasts) [PDF]

open access: yesThe Egyptian Statistical Journal, 1995
This paper introduces the general idea of error contrasts, their properties, and uses. Error contrasts is a way for partitioning the error space and depend on it's canonical representation, that is the vector space of linear unbiased estimators of zero ...

Decentralized Integral Nested Sliding Mode Control for Time Varying Constrained Modular and Reconfigurable Robot

open access: yesAdvances in Mechanical Engineering, 2015
This paper presents a novel decentralized integral nested sliding mode control approach for a time varying constrained modular and reconfigurable robot (MRR) and addresses the problem of joint trajectory tracking control of the MRR with strongly coupled ...

Bayesian system identification for structures considering spatial and temporal correlation

open access: yesData-Centric Engineering, 2023
The decreasing cost and improved sensor and monitoring system technology (e.g., fiber optics and strain gauges) have led to more measurements in close proximity to each other.

A 2D Nested Array Based DOA Estimator for Incoherently Distributed Sources via Sparse Representation Utilizing L1-Norm

open access: yesInternational Journal of Antennas and Propagation, 2019
Nested arrays are sparse arrays composed of subarrays with nonuniform sensor spacing. Compared with traditional uniform arrays, nested arrays have more degree of freedoms (DOFs) and larger apertures.
