Mobile Sensor Networks for Air Quality Monitoring in Urban Settings

Adrian Arfire

With urban populations rapidly increasing and millions of deaths being attributed annually to air pollution, there is a critical need for a deeper understanding of urban air quality. The locality of urban emissions sources, and the specific topography of c ...

EPFL2016

, ,

Systematic physical model tests are performed on a stepped spillway equipped with a bottom aerator at the beginning of the stepped part. A deflector is used to issue a jet in order to initiate air entrainment into the flow. A horizontal slot located in the ...

Semantic Data Layers in Air Quality Monitoring for Smarter Cities

Karl Aberer, Julien Eberle, Jean Paul Calbimonte Perez

Air pollution is one of the key indicators for quality of life in urban environments, and is also the subject of global health concern, given the number of mortal diseases associated to exposure to pollutants. Assessing and monitoring air quality is an imp ...

Land in the southeastern U.S. is expected to change, e.g., given the potential demand to develop forest-to-fuel technologies or, conversely, cropification of current forests to increase food production. Possible future PM2.5 and O3 ai ...

Elsevier2015

Impacts of emissions changes from four potential U.S. CO2 emission reduction policies on 2050 air quality are analyzed using the community multiscale air quality model (CMAQ). Future meteorology was downscaled from the Goddard Institute for Spac ...

Comparison of chute aerator effect on stepped and smooth spillways

Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier

Bottom chute aerators are installed to prevent cavitation damages and they have been studied in detail on smooth spillways. In parallel, stepped spillways became widespread in the past decades. Research has shown that stepped spillways may be endangered ev ...

Gas Sensing Properties of Metal-decorated Tungsten Oxide Nanowires Directly Grown onto Flexible Polymeric Hotplates

Danick Briand, El Hadji Malick Camara, José Luis Ramirez Falo

Aerosol assisted CVD (AACVD) is a self-catalyzed method that allows for growing single crystalline metal oxide nanowires at moderate temperatures (i.e. up to 380C). This is employed here to grow either Pt or Au-decorated tungsten oxide nanowires directly o ...

The 2010 California Research at the Nexus of Air Quality and Climate Change (CalNex) field study

Athanasios Nenes

The California Research at the Nexus of Air Quality and Climate Change (CalNex) field study was conducted throughout California in May, June, and July of 2010. The study was organized to address issues simultaneously relevant to atmospheric pollution and c ...

Mobile observatory: an exploratory study of mobile air quality monitoring application

Karl Aberer, Julien Eberle, Yongsung Kim, Erol Can Ün, Riikka Maria Vilhelmiina Hänninen

We present Mobile Observatory, a mobile air quality monitoring application that provides evaluation of air quality of the city of Zurich, Switzerland. As Mobile Observatory utilizes air quality data gathered by sensors mounted on around 10 trams in Zurich, ...

A model-based back-end for air quality data management

Karl Aberer, Julien Eberle, Yongsung Kim, Erol Can Ün

In this paper we present a hybrid model for real-time query processing over data stream collected by mobile air quality sensors. First, we introduce a novel indexing scheme for representing air quality and use it for generating and evaluating a static mode ...
