Ambulatory measurement of ankle kinetics for clinical applications

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

This study aimed to design and validate the measurement of ankle kinetics (force, moment, and power) during consecutive gait cycles and in the field using an ambulatory system. An ambulatory system consisting of plantar pressure insole and inertial sensors ...

Peak neoclassical toroidal viscosity at low toroidal rotation in the DIII-D tokamak

Holger Reimerdes

Observation of a theoretically predicted peak in the neoclassical toroidal viscous (NTV) force as a function of toroidal plasma rotation rate is reported. The NTV was generated by applying n = 3 magnetic fields from internal (I-)coils to low plasmas produc ...

Force feedback keyboard: self sensing

Yves Chevallier

Within the framework of a project consisting in developing a haptic keyboard, each key is aimed to be controlled individually in position and force. Small sized actuators has already been designed and integrated in a 64 keys force feedback keyboard. The pr ...

Response of an embedded block impacted by high-velocity jets

Matteo Paolo Elia Antonio Federspiel

The safety of dams is very often endangered by the formation of scour near the foundation as a result of high-velocity jet impact. These jets issue from appurtenant structures such as spillways and may impact in the immediate vicinity of the dam toe. The p ...

Multiplicity Of Homoclinic Orbits In Quasi-Linear Autonomous Lagrangian Systems

Boris Buffoni, Laurent Landry

The existence of at least two homoclinic orbits is proved by A. Ambrosetti and V. Coti Zelati (Multiple homoclinic orbits for a class of conservative systems, Rend. Sem. Mat. Univ. Padova, 89 (1993), 177-194) for autonomous Lagrangian systems ...

Fluctuations of the Casimir-like force between two membrane inclusions

Anne-Florence Raphaëlle Bitbol

Although Casimir forces are inseparable from their fluctuations, little is known about these fluctuations in soft matter systems. We use the membrane stress tensor to study the fluctuations of the membrane-mediated Casimir-like force. This method enables u ...

Dynamic analysis of laminated composite plates traversed by a moving mass based on a first-order theory

Elyas Ghafoori

The dynamic response of angle-ply laminated composite plates traversed by a moving mass or a moving force is investigated. For this purpose, a finite element method based on the first-order shear deformation theory is used. Stationary and adaptive mesh tec ...

A novel verticalized reeducation device for spinal cord injuries, the WalkTrainer: from design to the clinical trials

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Jacques Fournier, Yves Allemand

Robotic assistive devices have been developed and are now being introduced in clinical environments. Such robots can advantageously provide long raining, with quantifiable mobilization (force and position). But in the event of a complete lesion the patient ...

Silicon microcantilevers with MOSFET detection

Luis Guillermo Villanueva Torrijo

We report the fabrication of silicon microcantilevers with MOSFET detection, to be used in force measurements for biomolecular detection. Thin cantilevers are required for a high force sensitivity. Therefore the source and drain of the transistors have bee ...
