AbstractWe study the overdamped motion of a particle in a one‐dimensional periodic potential driven by a stochastic force. If the stochastic force is correlated in time (non‐white), and if the potential has no inversion symmetry, a current is generated. In the case of a piecewise linear potential we obtain a closed expression for the current as a ratio

Electrical transport and noise in polyacene semiconductors
Journal of Computational Electronics, 2012Measurements of electrical transport and excess current noise in semiconducting films of polyacenes revealed a superquadratic increase of the current and a sharp peak of the relative noise at voltage values corresponding to the trap-filling transition region.

Noise-Induced Transport with Low Randomness
Physical Review Letters, 2002We study the transport of overdamped Brownian particles in periodic potentials subject to a spatially modulated Gaussian white noise. We derive an analytical expression for the diffusion coefficient of particles. By means of velocity, diffusion coefficient, and their ratio (Péclet number) we discuss (a) symmetric potential and modulation of noise ...

A brief review of air transport noise
Journal of Sound and Vibration, 1974Abstract Flight vehicles are characterized according to their manner of operation and type of propulsion system; and their associated sources of noise are identified. Available noise reduction technology as it relates to engine cycle design and to power plant component design is summarized.

Transportation noise and cardiovascular health: role of multiple noise sources
Occupational and Environmental Medicine, 2019Links between exposure to transportation noise and cardiovascular health have been intensively studied during the past decade, and in Europe transportation noise has been listed as a major environmental health burden second only to air pollution.1 The increasing number of studies is partly due to the development of environmental noise modelling methods

Semiconductor noise in the framework of semiclassical transport
Physical Review B, 1996The paper describes an approach to semiconductor noise analysis that is entirely within the framework of the semiclassical transport theory. The key aspect that differentiates this approach from other noise models is that this approach directly connects noise characteristics with the physics of scattering in the semiclassical transport model and makes ...

The Effect of Transport Noise on Interface Formulation
Results in MathematicsThe authors discuss a mass conserving Allen-Cahn equation with a small parameter perturbed by transport type noise. To construct the hypersurface driven by the stochastic term, the two-dimensional domain is considered. An asymptotic expansion method is applied.

Transportation Noise Pollution and Cardiovascular Health
Circulation ResearchEpidemiological studies have found that transportation noise increases the risk for cardiovascular morbidity and mortality, with solid evidence for ischemic heart disease, heart failure, and stroke. According to the World Health Organization, at least 1.6 million healthy life years are lost annually from traffic-related noise in Western Europe. Traffic

Transport noise: a challenge for sustainable mobility
International Social Science Journal, 2003The paper starts with a brief overview of the impacts and perception of noise in the past in Europe. It has been well known for about 30 years that transport noise over critical levels causes serious annoyance. Moreover, recent epidemiological research indicates that it might also be responsible for a significant number of potentially fatal heart ...
