Sparse Density Estimation with Measurement Errors [PDF]

open access: yesEntropy, 2021
This paper aims to estimate an unknown density of the data with measurement errors as a linear combination of functions from a dictionary. The main novelty is the proposal and investigation of the corrected sparse density estimator (CSDE).

Feature-Based Characterisation of Turned Surface Topography with Suppression of High-Frequency Measurement Errors [PDF]

open access: yesSensors, 2022
Errors that occur when surface topography is measured and analysed can be classified depending on the type of surface studied. Many types of surface topographies are considered when frequency-based errors are studied.

Passive Measurement of Three Optical Beacon Coordinates Using a Simultaneous Method

open access: yesSensors, 2021
Among other things, passive methods based on the processing of images of feature points or beacons captured by an image sensor are used to measure the relative position of objects.

A Parametric Bootstrap Approach for a One-Way Error Component Regression Model with Measurement Errors

open access: yesMathematics, 2023
In this paper, a one-way error component regression model with measurement errors is considered. The unknown parameter vector is estimated by using the bias-corrected method, and its corresponding asymptotic properties are also developed.

Welfare Measurement and Measurement Error [PDF]

open access: yesReview of Economic Studies, 2001
There is investigated the differential effect of a measurement error for some inequality and poverty measures. It is studied the relationship between the impact of this error and the form of the underlying structural income distribution. All conclusions are based on a good mathematical background.

Robust adaptive Kalman filter for strapdown inertial navigation system dynamic alignment

open access: yesIET Radar, Sonar & Navigation, 2021
The measurement noise covariance R plays a vital role in the Kalman filter (KF) algorithm. Traditionally, a constant R is obtained by experience or experiments.

Contaminations on Lidar Sensor Covers: Performance Degradation Including Fault Detection and Modeling as Potential Applications

open access: yesIEEE Open Journal of Intelligent Transportation Systems, 2022
Lidar sensors play an essential role in the perception system of automated vehicles. Fault Detection, Isolation, Identification, and Recovery (FDIIR) systems are essential for increasing the reliability of lidar sensors.
