Integrating chemical analysis and bioanalysis to evaluate the contribution of wastewater effluent on the micropollutant burden in small streams

Juliane Hollender

Surface waters can contain a range of micropollutants from point sources, such as wastewater effluent, and diffuse sources, such as agriculture. Characterizing the source of micropollutants is important for reducing their burden and thus mitigating adverse ...

On an Analytical, Spatially-Varying, Point-Spread-Function

Paul Hurley, Matthieu Martin Jean-André Simeoni, Adrien Georges Jean Besson

The point spread function (PSF), namely the response of an ultrasound system to a point source, is a powerful measure of the quality of an imaging system. The lack of an analytical formulation inhibits many applications ranging from apodization optimizatio ...

Options and limitations for bromate control during ozonation of wastewater

Urs von Gunten

Wastewater treatment plants (WWTPs) are important point sources for micropollutants, which are harmful to freshwater organisms. Ozonation of wastewater is a powerful option to abate micropollutants, but may result in the formation of the potentially toxic ...

Point and sensor estimation from images

Martin Vetterli, Adam James Scholefield, Alireza Ghasemi

System comprising at least one sensor configured to take a set of images from different viewpoints of a scene; a processor configured to identifying a point source represented in the images of a set of images; computing for each image of the set of images ...

White Paper on the Application of Molecular, Spectroscopic, and Other Novel Methods to Monitor Pathogens for Potable Reuse

Tamar Kohn, Krista Rule Wigginton, Brian Pecson

Direct potable reuse (DPR) is gaining interest in water-scarce and water-conscious regions of the world as a technology capable of treating domestic wastewater to potable water standards. Because wastewater is the source water of such treatment schemes, th ...

Firedec: a two-channel finite-resolution image deconvolution algorithm

Frédéric Courbin, Pascale Jablonka, Georges Meylan, Malte Tewes, Nicolas Cantale

We present a two-channel deconvolution method that decomposes images into a parametric point-source channel and a pixelized extended-source channel. Based on the central idea of the deconvolution algorithm proposed by Magain et al. (1998, ApJ, 494, 472), t ...

Solar disinfection (SODIS) of viruses in PET bottles

Tamar Kohn, Anna Carratala Ripolles, Michael Jon Mattle, Alex Dionisio Calado

Solar disinfection of drinking water in PET bottles (SODIS) is a simple point-of-use technique efficient for the inactivation of many bacterial pathogens. In contrast, the efficiency of SODIS toward viruses is not well known. In this work, we studied the i ...

High-contrast self-imaging with ordered optical elements

Hans Peter Herzig, Ali Naqavi, Mattia Rossi

Creating arbitrary light patterns has applications in various domains, including lithography, beam shaping, metrology, sensing, and imaging. We study the formation of high-contrast light patterns obtained by transmission through an ordered optical element ...

A Large Eddy Simulation to determine the effect of trees on wind and turbulence over a suburban surface

Marc Parlange, Marco Giovanni Giometto, Andreas Christen

A proper modeling of flow and turbulence within and over urban canopies is key to properly predict air pollution and dispersion in cities. Trees are an integral part of the urban landscape. In many suburban neighborhoods, tree cover is 10 to 30% and trees ...
