AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Formaldehyde is a primary and secondary air pollutant. As an intermediate product of hydrocarbon photooxidn., it contributes to the formation of photochem. pollution in urban areas. In addn., chronic or acute exposure to HCHO (a possible carcinogen) consti ...
Measurements of local air pollution and road traffic were taken during a period of one month before and after the opening of a road tunnel to the public in nearby Sachseln, a small city located in a rural region (Obwald) at the center of Switzerland. Two 5 ...
The LIDAR principle for air quality and meteorol. measurements is presented, followed by different examples of vertical O3 profiles and time series obtained with a new optical layout of the EPFL-LPAS DIAL system using dual telescope detection. These data w ...
Regional budgets of pollutants in the atmospheric boundary layer (ABL) provide valuable information on transport and chemical processes, especially over complex terrain where local assessments are not representative. Horizontal transport, vertical transpor ...
One can observe a growing awareness, also outside the circle of experts, of the overriding importance of comfort in buildings; be it visual, thermal or acoustic comfort or comfort related to indoor air quality. This awareness has been intensified by the di ...
Using control theory, apredictive thermal regulation of the "certainty equivalence" type has been developped. Stochastic models of hourly solar rediation and outdoor air temperature, based on the theory of Markov and ARMA processes, were set up for this pu ...
Oxidative potential (OP), which is the ability of certain components in atmospheric particles to generate reactive oxidative species (ROS) and deplete antioxidants in vivo, is a prevailing toxicological mechanism underlying the adverse health effects assoc ...
