Point source identification in non-linear advection-diffusion-reaction systems

, 2013
We consider a problem of identification of point sources in time dependent advection-diffusion systems with a non-linear reaction term. The linear counterpart of the problem in question can be reduced to solving a system of non-linear algebraic equations

Lead Isotope Ratio Measurements for Source Identification Using Samples from the UK Heavy Metals Air Quality Monitoring Network

Atmosphere
Lead isotope ratios vary depending on the origin of the lead, meaning that characteristic isotopic signatures can be used for source identification in environmental samples.

Estimation of contamination release histories using meshless radial point collocation method and multiverse optimization

Journal of Hydroinformatics, 2023
Contaminants in groundwater may enter through various sources which are required to be identified for informed decision-making regarding remediation. In early stages of contamination of an aquifer, the sources of contamination are generally unknown.

Infection Spreading and Source Identification: A Hide and Seek Game

, 2015
The goal of an infection source node (e.g., a rumor or computer virus source) in a network is to spread its infection to as many nodes as possible, while remaining hidden from the network administrator.

Auditory time-interval perception as causal inference on sound sources

Frontiers in Psychology, 2012
Perception of a temporal pattern in a sub-second time scale is fundamental to conversation, music perception, and other kinds of sound communication. However, its mechanism is not fully understood. A simple example is hearing three successive sounds with

On Reduced Input-Output Dynamic Mode Decomposition

, 2017
The identification of reduced-order models from high-dimensional data is a challenging task, and even more so if the identified system should not only be suitable for a certain data set, but generally approximate the input-output behavior of the data ...

Source identification for mobile devices, based on wavelet transforms combined with sensor imperfections [PDF]

, 2013
One of the most relevant applications of digital image forensics is to accurately identify the device used for taking a given set of images, a problem called source identification.
