A wrist sensor and algorithm to determine instantaneous walking cadence and speed in daily life walking

Kamiar Aminian, Pierre-André Farine, Flavien Bardyn, Benedikt Fasel, Cyntia Duc, Farzin Dadashi, Martin Savary

In daily life, a person’s gait—an important marker for his/her health status—is usually assessed using inertial sensors fixed to lower limbs or trunk. Such sensor locations are not well suited for continuous and long duration measurements. A better locatio ...

Comparison and combination of reduced order modelling techniques in 3D parametrized heat transfer problems

Gianluigi Rozza, Fabrizio Gelsomino

Reduced Basis (RB) method has successfully been used in 2D to solve heat transfer parametrized problems. In this work, we present some 3D applications in the same field. We consider two problems, the steady Thermal Fin and the time dependent Graetz Flow, w ...

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 ...

Benefits of Continuous Descent Operations in High-Density Terminal Airspace Considering Scheduling Constraints

Maryam Kamgarpour

This study estimates the potential benefits of continuous descents for more than 480,000 flights to 25 major airports in the National Airspace System. While reduced fuel consumption and greenhouse gas emissions are expected for these procedures, the benefi ...

Ultra-low pressure sensor for neonatal resuscitator

Peter Ryser, Thomas Maeder, Caroline Jacq, Nicolas Craquelin, Enrico Haemmerle

A Venturi-type flow sensor has been designed and fabricated for neonatal respiratory assistance to control airway pressure and tidal volume. As the low flow range and sensing principle require the measurement of correspondingly very low pressures, a very r ...

Real-Time Reliable Simulation of Heat Transfer Phenomena

Gianluigi Rozza

In this paper we discuss the application of the certified reduced basis method and the associated software package rbMIT (c) to ``worked problems'' in steady and unsteady conduction. Each worked problem is characterized by an input parameter vector --- mat ...

Vision-based control of near-obstacle flight

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

This paper presents a novel control strategy, which we call optiPilot, for autonomous flight in the vicinity of obstacles. Most existing autopilots rely on a complete 6-degree-of-freedom state estimation using a GPS and an Inertial Measurement Unit (IMU) a ...

Highly sensitive vertical hall sensors in CMOS technology

Enrico Schurig

Vertical Hall sensors are capable of measuring surface-parallel components of the magnetic field. They allow therefore relatively easy conception of single-chip multi-axial magnetic sensors compared to solutions using horizontal Hall plates. The modern tre ...

Chlorosulfonic acid

Albert Renken

High-purity HSO3Cl is prepd. at a high space-time yield by mixing and reacting gaseous HCl with SO3 dissolved in ClSO3H, contg. 0.3-1.4% SO3 at 70-100 Deg in a venturi tube at 1-1.1 mol HCl/mol SO3. Thus, into the throat of a vertical venturi tube was fed ...
