A New Stopping Sight Distance Model and Fuzzy Reliability Analysis Comparison

open access: yesIEEE Access, 2022
Aiming at the problem that the existing stopping sight distance model is out of sync with the development of the times, this paper puts forward a new stopping sight distance model considering the fuzziness and randomness of design parameters, and deduces

Attentional Differences as a Function of Rock Climbing Performance

open access: yesFrontiers in Psychology, 2020
The purpose of this study was to investigate the relationship between attention (using two different attention tasks) and self-reported climbing ability while considering potential confounding factors (sex, age, climbing experience, and cardiorespiratory

Modeling of kinematic characteristics of the line of sight of a mobile antenna of a spacecraft when it is pointed at an information reception point

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
Within the framework of the general problem of calculating the kinematic characteristics of the mobile antenna of the spacecraft, the problem of the kinematics of the complex movement of the line of sight "Sc — IRP" ("spacecraft — information reception ...

Gravitational Lensing by Dark Matter Caustics [PDF]

open access: yes, 2003
Dark matter caustics have specific density profiles and, therefore, precisely calculable gravitational lensing properties. We present a formalism which simplifies the relevant calculations, and apply it to four specific cases.

Calculating TIN-Based 3D Sight Distance and Its Evaluation on Drivers Free-Flow Speed

open access: yesShock and Vibration, 2021
Sight distance during driving may be limited by side factors such as mountain slopes or trees and buildings in horizontal curves and by the dome of the arc in vertical curves, and the night vision also can be limited in the sag vertical curves by the ...

Showing Seeing in Film

open access: yesErgo, An Open Access Journal of Philosophy, 2021
In this paper, we describe two film conventions for representing what a character sees: point of view (POV) and sight link. On a POV interpretation, the viewpoint of a shot represents the viewpoint of a particular character; while in sight link, a shot ...
