High‐precision simulation technology for enhanced Loran signal simulators based on Lagrange farrow structure filter

open access: yesIET Radar, Sonar & Navigation, 2023
In this study, a real‐time high accuracy signal simulation technique for an enhanced Loran (eLoran) signal simulator is proposed, which can be used to verify the performance of the eLoran receiver.

Location errors in time of arrival (TOA) and time difference of arrival (TDOA) systems [PDF]

open access: yes, 1977
It is shown that the covariance matrix of object location errors is identical for time of arrival (TOA) and time difference of arrival (TDOA) systems if the inverse of the covariance matrix of TOA (TDOA) errors is used as a weighting matrix. Also, with this weighting the location errors statistics do not depend on the particular difference pairs in the

mmWave V2V Localization in MU-MIMO Hybrid Beamforming

open access: yesIEEE Open Journal of Vehicular Technology, 2022
Recent trends for vehicular localization in millimetre-wave (mmWave) channels include employing a combination of parameters such as angle of arrival (AOA), angle of departure (AOD), and time of arrival (TOA) of the transmitted/received signals ...

Dual Effect of Steric Hindrance in Non‐Aqueous Amine Absorbents: Navigating the Trade‐Off Between Kinetics and Thermodynamics for Efficient CO2 Capture

open access: yesAdvanced Science, EarlyView.
This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.

Merging Psychological, Social, and Rational Perspectives: A Study of the Determinants of Consumer Choices for Sustainable Furniture

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines consumer purchase intentions for a sofa produced through industrial symbiosis (IS), utilizing recycled textiles and fibers. As a high‐investment product, the IS sofa requires a significant financial commitment and involves complex decision‐making, an area less studied compared with other sustainable goods categories.
