Differential-Damper Topologies for Actuators in Rehabilitation Robotics

Differential-damper (DD) elements can provide a high bandwidth means for decoupling a high inertia, high friction, non-backdrivable actuator from its output and can enable high fidelity force control. In this paper, a port-based decomposition is used to an ...

Coded SC-FDMA for broadband satellite return links

Stefano Rosati

In this paper we deal with Single Carrier Frequency Division Multiple Access (SC-FDMA) as uplink air interface of broadband satellite networks. Interestingly, SC-FDMA enables a significant increase of the spectral efficiency with respect to the state-of-th ...

Hybrid BOTDA/FBG sensor for discrete dynamic and distributed static strain/temperature measurements

Marcelo Alfonso Soto Hernandez

We propose and experimentally demonstrate a hybrid fiber optic sensing technique that effectively combines Brillouin optical time-domain analysis and a time-domain multiplexing interrogation technique for Fiber Bragg Gratings (FBGs). The highly-integrated ...

Design of a miniature laser scanning head for high-bandwidth, low-amplitude beam steering

Yves Bellouard, Reymond Clavel

In laser micro-manufacturing, one of the challenges is to achieve fast scanning speed for fast fabrication of complex 3D microstructures. For microstructures with nanoscale features, it is often desirable to steer laser beams from a few microns to a few te ...

Fast download but eternal seeding: The reward and punishment of Sharing Ratio Enforcement

Rameez Rahman

Many private BitTorrent communities employ Sharing Ratio Enforcement (SRE) schemes to incentivize users to contribute their upload resources. It has been demonstrated that communities that use SRE are greatly oversupplied, i.e., they have much higher seede ...
