Toward compression of small cell population: Harnessing stress in passive regions of dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Alexandre Poulin

We present a dielectric elastomer actuator (DEA) for in vitro analysis of mm2 biological samples under periodic compressive stress. Understanding how mechanical stimuli affect cell functions could lead to significant advances in diseases diagnosis and drug ...

Unsteady Aerodynamics of Low-Pressure Steam Turbines Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

Nonsynchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to ro ...

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 ...

Bioclimatic Design in Casablanca (Morocco): Decision Support through Building Performance Simulation

Shady Galal Mohamed Attia

In this paper, bioclimatic design strategies in Moroccan architecture have been analyzed for the city of Casablanca. The aim of this study is to enable architects to re-understand the lessons of tradition, because the way towards bioclimatic architecture s ...

Sensor placement for predicting airflow around buildings to enhance natural ventilation

Ian Smith, Maria Papadopoulou

It is a challenge to design buildings that are both energy efficient and healthy. The factors that contribute to energy efficient and healthy buildings are related to both indoor and outdoor conditions. For example, the airflow around naturally ventilated ...

Toward Assessing the Sensitivity of Buildings to Changes in Climate

Marilyne Andersen, Parag Rastogi, Sönke Frederik Horn

Substantial numbers of existing and new buildings are expected to survive long enough to experience perceptible shifts in climate ‘normals’ (averages). To predict a building's response to changes in typical weather, two inputs are required: weather data re ...

Toward Assessing the Sensitivity of Buildings to Changes in Climate

Sönke Frederik Horn

A building is designed for one set of typical climatic conditions. In the context of expected climate change, substantial numbers of existing and new buildings are expected to survive long enough to experience perceptible shifts in climate ‘normals’ (avera ...

Infiltration in soils with a saturated surface

David Andrew Barry, Marc Parlange

An earlier infiltration equation relied on curve fitting of infiltration data for the determination of one of the parameters, which limits its usefulness in practice. This handicap is removed here, and the parameter is now evaluated by linking it directly ...

Unsteady Aerodynamics of Low-Pressure Steam Turbines Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

Non-synchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to r ...
