Homogenization of a multiscale viscoelastic model with nonlocal damping, application to the human lungs

We are interested in the mathematical modeling of the deformation of the human lung tissue, called the lung parenchyma, during the respiration process. The parenchyma is a foam-like elastic material containing millions of air-filled alveoli connected by a ...

Active House: new buildings for sustainable architecture

Arianna Brambilla

Buildings consume more than 40% of all the energy we use, and about 50% of it is used for the conditioning systems, for this reason it is important to work on the energy demand, improving the buildings behaviour, in order to save the environment of the fut ...

Development of electroacoustic absorbers as soundproofing solutions for industrial ventilation systems

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Victor Desarnaulds

In many industrial environments, room and cavity modes may severely strengthen the annoyance of low frequency noises, such as in ventilation equipments. Moreover, there is an obvious technological gap in the state-of-the-art relative to low-frequency sound ...

Electrical impedance tomography system based on active electrodes

Peter Seitz

Electrical impedance tomography (EIT) can image the distribution of ventilated lung tissue, and is thus a promising technology to help monitor patient breathing to help selection of mechanical ventilation parameters. Two key difficulties in EIT instrumenta ...

First-principles study of high-field piezoelectricity in tetragonal PbTiO3

Anindya Roy, Massimiliano Stengel

We calculate from first principles the nonlinear piezoelectric response of ferroelectric PbTiO3 for the case of a polarization-enhancing electric field applied along the tetragonal axis. We focus mainly on the case of fixed in-plane lattice constants, corr ...

Anatomy-driven design of a prototype video laryngoscope for extremely low birth weight infants

Eric Tremblay

Extremely low birth weight (ELBW) infants frequently require endotracheal intubation for assisted ventilation or as a route for administration of drugs or exogenous surfactant. In adults and less premature infants, the risks of this intubation can be great ...

Flexible and stretchable micro-electrodes for in vitro and in vivo neural interfaces

Stéphanie Lacour

Microelectrode arrays (MEAs) are designed to monitor and/or stimulate extracellularly neuronal activity. However, the biomechanical and structural mismatch between current MEAs and neural tissues remains a challenge for neural interfaces. This article desc ...

Forecasting respiratory rate in sedated patients with partial least squares regression

Jérémie Guignard

Remifentanil, like the other sedative drugs used to achieve conscious sedation, has an impact on the efficiency of patient ventilation. Since the quality of breathing has an indirect effect on blood O2 and CO2 concentrations, keeping patients' blood homeos ...

Albedo effect on radiative errors in air temperature measurements

Michael Lehning, Marc Parlange, Chad Higgins, Marc-Olivier Boldi

Most standard air temperature measurements are subject to significant errors mainly due to sensor heating by solar radiation, even when the measurement principle is accurate and precise. We present various air temperature measurements together with other m ...

Qualitative modelling of the natural ventilation potential in urban context

Mario Germano

The two objectives of natural ventilation in buildings are the improvement of indoor air quality and thermal comfort. The methodology proposed hereafter provides an assessment of the natural ventilation potential for indoor air quality, while taking into c ...
