Electronic transport in graphene with out-of-plane disorder

Real-world samples of graphene often exhibit various types of out-of-plane disorder-ripples, wrinkles and folds-introduced at the stage of growth and transfer processes. These complex out-of-plane defects resulting from the interplay between self-adhesion ...

Design of Low-Profile Compliant Transmission Mechanisms

Jamie Paik, Zhenishbek Zhakypov, Frédéric Henri Vaskin Giraud

Robotic origami design allows creating meso-scale robotic systems and mechanisms not limited by degrees of freedom, miniaturization and assembly downsides of conventional transmission mechanisms. However, unlike the traditional rigid approaches, robotic or ...

Stiffness Control With Shape Memory Polymer in Underactuated Robotic Origamis

Jamie Paik, Amir Firouzeh, Marco Salerno

Underactuated systems offer compact design with easy actuation and control but at the cost of limited stable con- figurations and reduced dexterity compared to the directly driven and fully actuated systems. Here, we propose a compact origamibased design i ...

Building Scene Models by Completing and Hallucinating Depth and Semantics

Mathieu Salzmann

Building 3D scene models has been a longstanding goal of computer vision. The great progress in depth sensors brings us one step closer to achieving this in a single shot. However, depth sensors still produce imperfect measurements that are sparse and cont ...

A Study on the Programming Structures for RRAM-based FPGA Architectures

Giovanni De Micheli, Xifan Tang, Pierre-Emmanuel Julien Marc Gaillardon, Gain Kim

Field Programmable Gate Arrays (FPGAs) can benefit non-volatility and high-performance by exploiting Resistive Random Access Memories (RRAMs). In RRAM-based FPGAs, the memories do not only replace the SRAMs and store configurations, but they can also repla ...

Contribution to the Ultra-Fast Charging of Electric Vehicles : The Configurable Modular Multilevel Converter (CMMC)

Rosa Martel Danoary Tsirinomeny

It is generally agreed that one of the drawbacks of a conventional vehicle is the inability to always reach the best operating point of the engine and the inability to regenerate the kinetic energy. Meaning, even with the help of the gearbox or automatic t ...

Controllable polarity fet based arithmetic and differential logic

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù

A logic gate with three inputs A, B, and C, and one output implementing a function MAJ(A,B,C)=AB+BC+A*C comprising two mutually exclusive transmission gates (TGs) connected in series, based on two parallel double-gate controllable polarity devices, a pol ...

The use of wavelet transform for an automated initialization in GPS/MEMS-IMU integration

Jan Skaloud, Adrian Wägli, Heidi Fournier

The main objective of this research is in automating the initialization phase of the MEMS-IMZ/GPS data integration. The motivation for this study is the special case where the before mentioned sensors are worn on a body (e.g. of an athlete) and where the u ...

Near-field optical images of subwavelength annular aperture arrays exhibiting an extraordinary transmission

Patrik Willi Hoffmann, Christian Santschi

In this paper, we present near-field optical images of nanostructures exhibiting an extraordinary transmission. These structures consist of annular aperture arrays engraved in a metallic film: they are quite promising structures for nanophotonics because o ...

A Closed Loop Control Strategy for a Frequency-Only Converter with High Efficiency

Alfred Rufer, Aziza Benaboud

Many electric power generators use gas turbines as power sources, coupled through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine. This paper proposes to replace the mechanical gearbox with a flex ...
