Very-High-Speed Miniaturized Permanent Magnet Motors: Design and Optimization

Yves Perriard, Guillaume Paul-André Burnand

This paper aims to present an optimization method for very-high-speed electrical machines based on multiphysical analytical models. Analytical models allow a fast design but have to be robust and reliable. The set of models presented is very complete and c ...

A Supervisory Control Structure for Voltage-Controlled Islanded DC Microgrids

Giancarlo Ferrari Trecate, Pulkit Nahata, Alessio La Bella

In this work, we propose a supervisory control structure in islanded DC microgrids such that a well scheduled and balanced utilization of various resources is achieved. Our supervisory control layer rests on top of a voltage-controlled primary layer and co ...

The influence of external electric fields on charge reorganization energy in organic semiconductors

Hongguang Liu, Weicong Huang

Charge reorganization energies (k) of inter-ring carbon-carbon (IRCC) bond connected conjugated polycyclics are shown to exhibit an electric-field-driven anisotropic character. An external electric field parallel to the IRCC linker(s) reduces k while the f ...

Light-Enhanced Blue Energy Generation Using MoS2 Nanopores

Aleksandra Radenovic, Andras Kis, Martina Lihter, Michael Graf, Dmitrii Unuchek, Aditya Sarathy

Blue energy relies on the chemical potential difference between solutions of high and low ionic concentrations, potentially providing an independent energy source at estuaries around the world. The energy conversion relies on reverse electrodialysis via io ...

Design of High Permittivity Polysiloxane Elastomers for Dielectric Elastomer Transducers

Philip Horst Caspari

Dielectric elastomer transducers consist of a dielectric elastomer between two compliant electrodes. When the elastic capacitor is electrically charged, the dielectric elastomer elongates until a balance of elastic and electrostatic force is reached. Elect ...

Attribute-Guided Sketch Generation

Yan Yan, Wei Wang, Xinya Chen

Facial attributes are important since they provide a detailed description and determine the visual appearance of human faces. In this paper, we aim at converting a face image to a sketch while simultaneously generating facial attributes. To this end, we pr ...

High voltage switch for compact bidirectional dc-dc converter driving dielectric electroactive polymer actuators

Yves Perriard, Yoan René Cyrille Civet, Morgan Almanza, Raphaël Johannes Charles Mottet, Lucas Pniak

Driving DEAs requires time-varying high voltage power supplies, up to 18kV for 200um polymer layers. HV amplifiers are commonly used but bulky and expensive. Designing embedded actuators requires compact and efficient powersupplies. Furthermore, only a lit ...

AC/DC Ratio Enhancement in Photoplethysmography Using a Pinned Photodiode

Christian Enz, Assim Boukhayma, Antonino Caizzone

Photoplethysmography (PPG) enables non-invasive vitals monitoring. Nevertheless, it is intrinsically limited by the extremely small AC/DC ratio, also called perfusion-index (PI). This increases the dynamic-range requirements to reliably process the PPG wav ...

Federated Generative Privacy

Boi Faltings, Aleksei Triastcyn

In this paper, we propose FedGP, a framework for privacy-preserving data release in the federated learning setting. We use generative adversarial networks, generator components of which are trained by FedAvg algorithm, to draw privacy-preserving artificial ...
