The shedding process of the Kármán vortices at the trailing edge of a 2D hydrofoil at high Reynolds numbers is investigated. The focus is put on the effect of the cavitation on the vortex street morphology. A direct insight is also provided on the role of the structural vibration on the cavitation inception. The shedding frequency, derived from the measurement of flow induced vibration, is foun...

12 AI MAGAZINE Recent advances in smart human-machine systems, including wearable robotic technologies and neural interfaces, which are able to detect conscious choice, decision, and intent from the patient, now allow the design of wearable robots and powered prostheses and exoskeletons that assist and work cooperatively with people with disabilities (figure 1). Recently, the U.S. Food and Drug...

This paper presents the conception of a Smart Low Power Temperature Sensor which is powered using ambient vibration energy. It is presented the architecture of the conception of the sensor to be implemented. This power system will be the main part of the power stage for a self-powered micro temperature sensor inside a distributed sensor network where accessibility to human being operators is ve...

Localisation of multiple active speakers in natural environments with only two microphones is a challenging problem. Reverberation degrades the performance of speaker localisation based exclusively on directional cues. This paper presents an approach based on audio-visual fusion. The audio modality performs the multiple speaker localisation using the Skeleton method, energy weighting, and prece...
