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 ...

Sparse separation of sources in 3D soundscapes [PDF]
, 2010 A novel blind source separation algorithm applicable to extracting sources from within 3D soundscapes is presented. The algorithm is based on constructing a binary mask based on directional information. The validity of filtering using binary masked based

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,

A dynamic latent variable model for source separation [PDF]
, 2018 We propose a novel latent variable model for learning latent bases for time-varying non-negative data. Our model uses a mixture multinomial as the likelihood function and proposes a Dirichlet distribution with dynamic parameters as a prior, which we call

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 ...

Source separation in middle- and low-income countries [PDF]
, 2013 This chapter argues that source-separating sanitation systems still have a limited, but potentially growing role in middle- and low-income countries. It notes that the drivers and constraints for introducing source separation on a larger scale differ ...

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.

Speech enhancement via combination of Wiener filter and blind source separation [PDF]
, 2011 Automatic speech recognition (ASR) often fails in acoustically noisy environments. Aimed to improve speech recognition scores of an ASR in a real-life like acoustical environment, a speech pre-processing system is proposed in this paper, which consists ...
