Relationship between Motor Estimation Error and Physical Function in Patients with Parkinson’s Disease [PDF]

open access: yesMedicines, 2020
Background: Motor estimation error is an index of how accurately one’s body movement is recognized. This study determines whether motor estimation error distance is a Parkinson’s disease (PD)- or age-related disability using a two-step task. Methods: The

Robust Relative Error Estimation [PDF]

open access: yesEntropy, 2018
Relative error estimation has been recently used in regression analysis. A crucial issue of the existing relative error estimation procedures is that they are sensitive to outliers.

Oscillation in a posteriori error estimation [PDF]

open access: yesNumerische Mathematik, 2021
AbstractIn a posteriori error analysis, the relationship between error and estimator is usually spoiled by so-called oscillation terms, which cannot be bounded by the error. In order to remedy, we devise a new approach where the oscillation has the following two properties.

Cooperative Guidance Considering Detection Configuration Against Target With a Decoy

open access: yesIEEE Access, 2020
We consider the scenario where two pursuers are required to intercept an enemy evader that launches a decoy. Under the assumption that all four aircrafts have first-order linear dynamic characteristics, a cooperative guidance law is designed in two ...

Observer-based speed estimation for vector controlled induction motors

open access: yesТехнічна електродинаміка, 2022
A speed observer for field-oriented controlled induction drives is presented. The proposed solution exploits the concept of the classic full-order flux observer which is adaptive to the rotor resistance variations. Due to the structural similarity of the

Nonparametric estimation of mean-squared prediction error in nested-error regression models [PDF]

open access: yes, 2005
Nested-error regression models are widely used for analyzing clustered data. For example, they are often applied to two-stage sample surveys, and in biology and econometrics.

FDSS-Based DFT-s-OFDM for 6G Wireless Sensing

open access: yesSensors, 2023
Integrated sensing and communications (ISAC) is emerging as a key technology of 6G. Owing to the low peak-to-average power ratio (PAPR) property, discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM) is helpful to ...
