Low-Power Wearable System for Real-Time Screening of Obstructive Sleep Apnea

David Atienza Alonso, Francisco Javier Rincon Vallejos, Srinivasan Murali, Grégoire Casimir Joseph Surrel

Obstructive Sleep Apnea (OSA) is one of the main sleep disorders, but only 10% of the cases are diagnosed. Moreover, there is a lack of tools for long-term monitoring of OSA, since current systems are too bulky and intrusive to be used continuously. In thi ...

A systems approche to regional energy Modeling with smart grid integrated distributed energy resources

Frédéric Louis François Babonneau, Alain Haurie

We provide an introduction to ETEM-SG, a robust linear programming approach specifically designed for regional energy systems analysis. This model can be used to provide prospective analyses of the long-term (30 years and more) evolution of multi-energy re ...

High-Speed Link With Trellis-Coded Modulation and Reed Solomon Coding

Andreas Peter Burg, Thomas Toifl, Giovanni Cherubini

A high-performance low-latency transmission system based on a concatenated code consisting of inner four-dimensional five-level pulse-amplitude-modulation (5-PAM) trellis-coded modulation and an outer Reed-Solomon (RS) code is proposed for a high-speed dat ...

An Adaptive PMU-Based Wide Area Backup Protection Scheme for Power Transmission Lines

Mohsen Kalantar Neyestanaki

This paper proposes a novel adaptive wide area backup protection scheme for transmission lines. In the proposed scheme, both the faulted line and fault location are determined by a limited number of synchronized phasor measurements. Based on phasor measure ...

Efficient Method Based on the Electromagnetic Time Reversal to Locate Faults in Power Network

Mario Paolone, Reza Razzaghi, Gaspard Lugrin, Hossein Mahmoudimanesh

A time reversal process for determining a fault location in an electrical power network comprising multi-conductor lines, comprises measuring at an observation point located anywhere along one of the multi-conductor lines, for each of the conductors of the ...

Programmable Self-assembly with Chained Soft Cells: An Algorithm to Fold into 2-D Shapes

Dario Floreano, Joshua Evan Auerbach, Jürg Markus Germann

Programmable self-assembly of chained modules holds potential for the automatic shape formation of morphologically adapted robots. However, current systems are limited to modules of uniform rigidity, which restricts the range of obtainable morphologies and ...

Fictive Axis Emulator-based State Feedback Vector Current Control for Single-Phase Voltage Source Converters

Alfred Rufer, Michail Vasiladiotis

This paper presents a vector current control method tailored for single-phase voltage source converters. In order to imitate the behavior of a three-phase system, the Fictive Axis Emulation (FAE) concept is employed. The latter is able to synthesize the ro ...

Behavioral high-frequency modeling of electrical motors

Ivica Stevanovic

Reliable simulations of electromagnetic interference in motor drive power electronic systems ask for accurate high-frequency motor models. A methodology for creating frequency dependent behavioral circuit models of ac electrical motors is presented in this ...
