Estimating and Calibrating MFMod

, 2019
This paper summarizes the World Bank's approach to identifying parameters for key equations in its macro structural model for countries where short sample sizes or major structural changes render traditional time-series approaches infeasible or yield unstable estimates.

Robust direct position determination methods in the presence of array model errors

EURASIP Journal on Advances in Signal Processing, 2018
Direct position determination (DPD) methods are known to have many advantages over the traditional two-step localization method, especially for low signal-to-noise ratios (SNR) and/or short data records.

Real-time state estimation in a flight simulator using fNIRS.

PLoS ONE, 2015
Working memory is a key executive function for flying an aircraft. This function is particularly critical when pilots have to recall series of air traffic control instructions. However, working memory limitations may jeopardize flight safety.

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Robust and Non-Parametric Regression Estimators for Predictive Mean Estimation in Stratified Sampling

Axioms
In modern survey sampling, particularly when using stratified random sampling (StRS), the existence of outliers and model mis-specifications is a daunting challenge to the conventional parametric and nonparametric methods of estimating parameters.

The Calibration of Weights by Calif Tool in the Practice of the Statistical Office of the Slovak Republic [PDF]

Revista Română de Statistică, 2015
The main scope of statistical surveys is to determine sample estimates. If some auxiliary population totals are available, an inferential step could enlarge precision. Calibration estimators are mostly used by statistical agencies.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
