Analysis of twist-rate effects in a progressive-rifling barrel using finite element method [PDF]
Science ProgressIn this study, a nonlinear finite element model of a 30 mm chain-gun barrel with progressive rifling was developed to investigate the influence of twist-law parameters on interior ballistic behavior and rifling-induced stresses.

A Microscopic Heterogeneous Traffic Flow Model Considering Distance Headway
Mathematics, 2022 The intelligent driver (ID) model characterizes traffic behavior with a constant acceleration exponent and does not follow traffic physics. This results in unrealistic traffic behavior. In this paper, a new microscopic heterogeneous traffic flow model is

Evaluating the Effect of Road Surface Potholes Using a Microscopic Traffic Model
Applied Sciences, 2023 Road surface wear leads to the formation of cracks and holes known as potholes. Potholes disrupt the smooth flow of traffic and can lead to accidents. The Intelligent Driver (ID) model is commonly employed but it assumes uniform traffic behavior for all ...

A Microscopic Traffic Flow Model Characterization for Weather Conditions
Applied Sciences, 2022 Road surfaces are affected by rain, snow, and ice, which influence traffic flow. In this paper, a microscopic traffic flow model based on weather conditions is proposed. This model characterizes traffic based on the weather severity index.

A Microscopic Traffic Model Considering Driver Reaction and Sensitivity
Applied Sciences, 2023 A new microscopic traffic model is proposed that characterizes driver response according to reaction and sensitivity. Driver response in the intelligent driver (ID) model is based on a fixed acceleration exponent and so does not follow traffic physics ...
