Performance Evaluation of T-Shaped Noise Barriers Covered with Oblique Diffusers Using Boundary Element Method

open access: yesArchives of Acoustics, 2019
One of the most effective designs to control the road traffic noise is the T-shaped barrier. The aim of this study was to examine the performance of T-shape noise barriers covered with oblique diffusers using boundary element method.

Finite-barrier corrections for multidimensional barriers in colored noise [PDF]

open access: yesPhysical Review E, 2019
The usual identification of reactive trajectories for the calculation of reaction rates requires very time-consuming simulations, particularly if the environment presents memory effects. In this paper, we develop a method that permits the identification of reactive trajectories in a system under the action of a stochastic colored driving.

Method of Acoustic Calculation of Traffic Noise Barriers [PDF]

open access: yesMATEC Web of Conferences, 2020
Installation of noise barriers is an efficient and relatively cheap way of protecting residential areas from traffic noise. This paper proposes a comprehensive method of calculation of noise barriers.

Acoustic Requalification of an Urban Evolving Site and Design of a Noise Barrier: A Case Study at the Bologna Engineering School

open access: yesApplied Sciences
The increase in new infrastructure development has raised closer attention to the environmental noise of new expansion areas. This study investigates the urban evolution of Terracini Street’s surrounding area in the Navile district, Bologna, Italy.

Using noise to break the noise barrier in circuits [PDF]

open access: yesSPIE Proceedings, 2005
Technology advances tend to reduce minimum dimensions and source voltages to maintain scaling rules. Both scaling trends make noise more critical, reduce yield and increase device parameter fluctuations. This paper presents a statistical model that permits the study of noise and parameter deviations on gates.

Analysing the acoustic performance of a nearly-enclosed noise barrier using scale model experiments and a 2.5-D BEM approach

open access: yesApplied Acoustics, 2020
This paper describes a scale modelling method to measure the acoustic performance of a nearly-enclosed barrier and the corresponding predictions using an existing 2.5-D Boundary Element Method (BEM) program.

Acoustic and structural design of a highway noise barrier

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Highway noise barriers are designed to mitigate the effects of traffic noise along the highway. Noise barriers primarily block the direct path of the sound between the source on the highway and the receiver exposed to the sound.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Novel evaluation of raptor silhouettes and bird-collision prevention patterns through indoor flight tunnel testing and field verification

open access: yesAvian Conservation and Ecology
Bird collisions resulting from the increase of transparent structures associated with urbanization are recognized as a significant factor contributing to the decline of bird populations, and various strategies have been proposed to mitigate these ...
