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

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

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 ...

Accurate Frequency Estimation of a Real Sinusoid by Three New Interpolators

open access: yesIEEE Access, 2019
Interpolators are widely employed in the frequency estimation of sinusoidal signals. However, for a real-valued sinusoidal signal, the existing interpolators do not consider the negative frequency component, which leads to a frequency estimation error ...
