Driving Behavior and Decision Mechanisms in Emergency Conditions

World Electric Vehicle Journal, 2022
In this article we used simulator experiments to explore the intelligent mechanisms of human decision-making. Three types of typical emergency scenarios were used in the experiment, in which Scenario 1 was used to analyze the driver’s choice to protect ...

Tacticity in chiral phononic crystals

Nature Communications, 2019
Here, the authors study the influence of tacticity on the dynamic behaviour of chiral structured periodic media comprising rotational inertia elements. This opens the way towards new mechanisms for wave control by exploiting spin-spin coupling mechanism.

Control of Environmental Noise [PDF]

Journal of the Air Pollution Control Association, 1973
The article reviews the current state of knowledge of noise and how people respond to noise. Sources of community noise are discussed and existing federal legislation pertaining to noise is mentioned. Methods of reducing the noise impact on communities from aircraft, surface transportation, and industrial sites are presented. Interior noise in industry,

Sound pressure-dependent acoustic absorption by perforated rigid-frame porous materials

Acta Acustica
Porous materials are one of the most common classes of sound absorbers for acoustic treatments. However, thin layers of these classical materials are not efficient at absorbing low-frequency sound waves, which is a practical shortcoming.

Characterization of the aircraft bay/landing gear coupling noise at low subsonic speeds and its suppression using leading-edge chevron spoiler

Advances in Mechanical Engineering, 2019
When the aircraft opens the bay door to let the landing gear either drop or retract, the incoming flow will result in a significant amount of coupling noise from the bay and the landing gear.
