Identifying and Estimating the Location of Sources of Industrial Pollution in the Sewage Network
Sensors, 2021 Harsh pollutants that are illegally disposed in the sewer network may spread beyond the sewer network—e.g., through leakages leading to groundwater reservoirs—and may also impair the correct operation of wastewater treatment plants.

Real time plasma equilibrium reconstruction in a Tokamak [PDF]
, 2008 The problem of equilibrium of a plasma in a Tokamak is a free boundary problemdescribed by the Grad-Shafranov equation in axisymmetric configurations. The right hand side of this equation is a non linear source, which represents the toroidal component of

Identification hyperbolic problems with the Neumann boundary condition
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 In the present study, an identification problem with the Neumann boundary condition for a one-dimensional hyperbolic equation is investigated. Stability estimates for the solution of the identification problem are established. Furthermore, a first order

Real-Time Equilibrium Reconstruction in a Tokamak [PDF]
, 2007 This paper deals with the numerical reconstruction of the plasma current density in a Tokamak and of its equilibrium. The problem consists in the identification of a non-linear source in the 2D Grad-Shafranov equation, which governs the axisymmetric ...

Time-dependent sources identification for transmission lines problems [PDF]
Advanced Electromagnetics, 2015 This paper is devoted to introduce an extension to the Linear Combination of Configuration Fields (LCCF). This new numerical method was designed to compute the time profile of an electromagnetic source radiating a specified electromagnetic field in all or part of the computational domain, for a specified duration.

Bayesian Numerical Homogenization [PDF]
, 2014 Numerical homogenization, i.e. the finite-dimensional approximation of solution spaces of PDEs with arbitrary rough coefficients, requires the identification of accurate basis elements.

Results in Applied Mathematics, 2023 We present a general observation on how to replace changes of material properties in limited regions within a domain with fictitious forcing terms in initial- and boundary-value problems associated with wave propagation and diffusion.

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.

Stable Identification of Sources Located on Interface of Nonhomogeneous Media
Mathematics, 2021 This paper presents a stable method for the identification of sources located on the separation interface of two homogeneous media (where one of them is contained by the other one), from measurement yielded by those sources on the exterior boundary of ...
