Sound delivery to listening point using tangent line method [PDF]

JASA Express Letters, 2023
In personal audio systems, sounds should propagate toward the listening point and attenuate beyond the listening point. This study deals with controlling directivity and distance attenuation using loudspeaker arrays.

Machine Vision-Based Method for Estimating Lateral Slope of Structured Roads

Sensors, 2022
Most of the studies on vehicle control and stability are based on cases of known-road lateral slope, while there are few studies on road lateral-slope estimation.

Is there difference and correlation between medial and lateral tibial plateau coronal obliquity in native knee? A radiographic study

Journal of Orthopaedics, Trauma and Rehabilitation, 2021
Background/Purpose Knee joint line is commonly defined as a tangent to medial and lateral tibial plateaus in various radiographic measurements. We aim to investigate radiographic differences between medial and lateral knee joint line coronal obliquity ...

Where we look when we drive with or without active steering wheel control. [PDF]

PLoS ONE, 2012
Current theories on the role of visuomotor coordination in driving agree that active sampling of the road by the driver informs the arm-motor system in charge of performing actions on the steering wheel.

Pursuit eye-movements in curve driving differentiate between future path and tangent point models. [PDF]

PLoS ONE, 2013
For nearly 20 years, looking at the tangent point on the road edge has been prominent in models of visual orientation in curve driving. It is the most common interpretation of the commonly observed pattern of car drivers looking through a bend, or at the

Phase Equilibria in the System CaO-SiO₂-La₂O₃-Nb₂O₅ at 1400 °C

Metals, 2021
CaO-SiO2-La2O3-Nb2O5 system is of great significance for the pyrometallurgical utilization of Bayan Obo tailing resources. In the present work, the phase equilibrium of this quaternary system at 1400 °C was determined by a thermodynamic equilibrium ...
