Wing and tail morphing in birds and drones

To aid humans in civilian tasks, future drones will have to operate in large cities that abound with difficult flight conditions such as confined spaces, obstacles, and turbulent air. Such drones must cruise efficiently to cover vast distances fast and als ...

Critical thickness of GaN on AlN: impact of growth temperature and dislocation density

Nicolas Grandjean, Pirouz Sohi, Denis Martin

Critical thickness and strain relaxation of c-plane GaN layers grown by molecular beam epitaxy on AlN were studied as a function of growth temperature and threading dislocation density (TDD). For this purpose we used AlN/sapphire templates and AlN single c ...

Dynamics of glide avalanches and snow gliding

Christophe Ancey

In recent years, due to warmer snow cover, there has been a significant increase in the number of cases of damage caused by gliding snowpacks and glide avalanches. On most occasions, these have been full-depth, wet-snow avalanches, and this led some people ...

Run-to-Run Disturbance Rejection for Feedforward Path Following of an Adaptively Controlled Unmanned Helicopter

Timm Faulwasser

We present a scheme for run-to-run disturbance rejection in optimization-based feedforward path following of a remotely piloted aircraft system (RPAS). The proposed scheme is based on the inter-run estimation of unknown disturbances, such as wind forces an ...

Thermal soaring flight of birds and unmanned aerial vehicles

Severin Leven

Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and unmanned aerial vehicles (UAVs). The solution is to make use of the so-called thermals, which are localized, warmer regions in the ...

PREDOMINANCE OF ZOOGLOEA SP. DURING AEROBIC GRANULAR SLUDGE BIOFILMS DEVELOPMENT FOR WASTEWATER TREATMENT

Christof Holliger, Pierre Rossi, Emmanuelle Rohrbach, David Gregory Weissbrodt, Samuel Lochmatter, Sirous Ebrahimi, Sébastien Gabus

Aerobic granular sludge (AGS) biofilm process is a sustainable technology for full biological nutrients removal (BNR) from municipal and agro-industrial wastewater, and for secondary clarification in single sequencing batch reactors (SBR). Fundamental rese ...

Towards a self-deploying and gliding robot

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey

Strategies for hybrid locomotion such as jumping and gliding are used in nature by many different animals for traveling over rough terrain. This combination of locomotion modes also allows small robots to overcome relatively large obstacles at a minimal en ...

A 1.5g SMA-actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Daniel Nicoud, Jean-Christophe Zufferey

Unpowered flight can be used in microrobotics to overcome ground obstacles and to increase the traveling distance per energy unit. In order to explore the potential of goal-directed gliding in the domain of miniature robotics, we developed a 22cm microglid ...

A 1.5g SMA actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Daniel Nicoud, Jean-Christophe Zufferey

Summarizing, we present a 1.5g gliding robot that can do phototaxis as a first step towards a novel palm sized self deploying microglider. To reduce the weight, we developed a 0.2g SMA actuator for rudder control that is harmoniously integrated in the airf ...
