Multiscale blind source separation [PDF]
The Annals of Statistics, 2018 We provide a new methodology for statistical recovery of single linear mixtures of piecewise constant signals (sources) with unknown mixing weights and change points in a multiscale fashion. We show exact recovery within an $ε$-neighborhood of the mixture when the sources take only values in a known finite alphabet.

Anaerobic digestion of dried/shredded food waste in a periodic anaerobic baffled reactor
Water Science and Technology, 2021 The objective of the current work is to study the impact of the operational parameters' variation (HRT, OLR and T) on biomethane productivity in a periodic anaerobic baffled reactor (PABR).

Nonlinear blind source separation for sparse sources [PDF]
2016 24th European Signal Processing Conference (EUSIPCO), 2016 Blind Source Separation (BSS) is the problem of separating signals which are mixed through an unknown function from a number of observations, without any information about the mixing model. Although it has been mathematically proven that the separation can be done when the mixture is linear, there is not any proof for the separability of nonlinearly ...

Integrated, Decentralized Wastewater Management for Resource Recovery in Rural and Peri-Urban Areas
Resources, 2017 Collection and treatment of wastewater have a huge impact on the environment and economy, both at the local and global levels. Eco-innovation may play a paramount role in the reduction of the environmental impact of such systems, and in their greater ...

Source separation and localisation via tensor decomposition for distributed arrays
The Journal of Engineering, 2019 This study focuses on the problem of power spectra separation and localisation of multiple sources using distributed arrays. First, the array structure and signal model are discussed. By cross-correlating the multi-channel received signals in time-domain,

High temperatures and CO2 dissolution can cause nitrogen losses from urine stabilized with base
Frontiers in Environmental Science, 2022 Human urine is rich in valuable nitrogen which can easily be lost due to biological urea hydrolysis and subsequent ammonia volatilization. While this enzymatic reaction can be prevented by alkalizing the urine, recent studies suggest that chemical urea ...

A Separation Method for Electromagnetic Radiation Sources of the Same Frequency [PDF]
Journal of Electromagnetic Engineering and Science, 2023 To separate electromagnetic interference sources with an unknown source number, a new separation method is proposed, which includes five key steps: spatial spectrum estimation, source number and direction-of-arrival estimation, mixed matrix estimation ...

Separation and Localisation of P300 Sources and Their Subcomponents Using Constrained Blind Source Separation [PDF]
EURASIP Journal on Advances in Signal Processing, 2006 Separation and localisation of P300 sources and their constituent subcomponents for both visual and audio stimulations is investigated in this paper. An effective constrained blind source separation (CBSS) algorithm is developed for this purpose.
