A Nonlinear Dynamic Strategy for Mathematical Modeling and Simulation of Stabilized Platform in Planar Motion in One Body and Three Bodies

Abstract Mathematical modeling and simulation of a head stabilization platform. The stabilization platform is capable of moving on the pitch degree of freedom. The platform is modeled in two different approaches; considering only the mass of the platform ( ...

Drones to the Rescue!

Jan Skaloud

The use of unmanned aerial systems for civilian search-and-rescue operations or disaster management is not new. Predators drones, commonly associated with military operations, were used in the aftermath of the hurricane Katrina in the United States; rotary ...

Alignment of angular velocity sensors for a vestibular prosthesis

Silvestro Micera

ABSTRACT: Vestibular prosthetics transmit angular velocities to the nervous system via electrical stimulation. Head-fixed gyroscopes measure angular motion, but the gyroscope coordinate system will not be coincident with the sensory organs the prosthetic r ...

Fault Detection and Isolation in Multiple MEMS-IMUs Configurations

Jan Skaloud, Stéphane Guerrier

This research presents methods for detecting and isolating faults in multiple micro-electro-mechanical system inertial measurement unit (MEMS-IMU) configurations. First, geometric configurations with n sensor triads are investigated. It is proved that the ...

Vertical "III-V" V-Shaped Nanomembranes Epitaxially Grown on a Patterned Si[001] Substrate and Their Enhanced Light Scattering

Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ludovit Pavel Zweifel

We report on a new form of III-IV compound semiconductor nanostructures growing epitaxially as vertical V-shaped nanomembranes on Si(001) and study their light-scattering properties. Precise position control of the InAs nanostructures in regular arrays is ...

A Hybrid Strategy for Real-Time Traffic Signal Control of Urban Road Networks

Anastasios Kouvelas

The recently developed traffic signal control strategy known as traffic-responsive urban control (TUC) requires availability of a fixed signal plan that is sufficiently efficient under undersaturated traffic conditions. To drop this requirement, the well-k ...

Robot Head Stabilization During Periodic Locomotion Using Adaptive Dynamical Systems

Auke Ijspeert, Sébastien Gay, José Santos-Victor

We present a gaze stabilization system using only visual information as feedback for a self tuning dynamical system. We describe how the dynamical system tunes its internal parameters to those of the optical ﬂow information to generate compensatory command ...

Multi-parametric Evaluation of Sit-to-Stand and Stand-to-Sit Transitions in Elderly People

Kamiar Aminian, Anisoara Ionescu, Raluca Lidia Ganea

The aim of this study was to extract multi-parametric measures characterizing different features of sit-to-stand (Si-St) and stand-to-sit (St-Si) transitions in older persons, using a single inertial sensor attached to the chest. Investigated parameters we ...
