Chaos and noise [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2013
Simple dynamical systems—with a small number of degrees of freedom—can behave in a complex manner due to the presence of chaos. Such systems are most often (idealized) limiting cases of more realistic situations. Isolating a small number of dynamical degrees of freedom in a realistically coupled system generically yields reduced equations with terms ...

Metallic Ti3C2Tx MXene Gas Sensors with Ultrahigh Signal-to-Noise Ratio.

open access: yesACS Nano, 2018
Achieving high sensitivity in solid-state gas sensors can allow the precise detection of chemical agents. In particular, detection of volatile organic compounds (VOCs) at the parts per billion (ppb) level is critical for the early diagnosis of diseases ...

Analysis and Optimization of Noise Response for Low-Noise CMOS Image Sensors [PDF]

open access: yes, 2012
CMOS image sensors are nowadays widely used in imaging applications and particularly in low light flux applications. This is really possible thanks to a reduction of noise obtained, among others, by the use of pinned photodiode associated with a ...

Numerical simulation of temperature variation in water layer induced by thermal jet in weak stratified environment

open access: yesAIP Advances, 2022
In order to explore the rising and diffusing path of an underwater thermal jet and the temperature variation of each water layer in the typical ocean thermohaline stratified environment, a three-dimensional mass-heat transport model of the thermal jet in

On the definition of noise

open access: yesHumanities and Social Sciences Communications, 2022
AbstractUrbanization has exposed people to extreme sound levels. Although researchers have investigated the ability of people to listen, analyze, and distinguish sound, the concept of noise has not been clearly articulated from a human perspective. The lack of knowledge on how people perceive noise limits our capacity to control it in a targeted manner.

An intelligent bearing fault diagnosis system: A review

open access: yesMATEC Web of Conferences, 2019
Rolling element bearing (REB) is a well-known component that most extensively used in the industry. They operate in extreme condition (high temperature, dirty environment) which may lead to unexpected failure after the certain operation.

Optical full Hadamard matrix multiplexing and noise effects [PDF]

open access: yes, 2009
Hadamard multiplexing provides a considerable SNR boost over additive random noise but Poisson noise such as photon noise reduces the boost. We develop the theory for full H-matrix Hadamard transform imaging under additive and Poisson noise effects.
