Resistive Coupled VO2 Oscillators for Image Recognition

Mihai Adrian Ionescu, Igor Stolichnov, Kirsten Emilie Moselund, Siegfried Karg, Elisabetta Corti

Oscillator networks are known for their interesting collective behavior such as frequency locking, phase locking, and synchronization. Compared to other artificial neural network implementations, timing rather than amplitude information is used for computa ...

Liquid electromigration in gallium-based biphasic thin films

Stéphanie Lacour, Hadrien Olivier Michaud

Liquid metals have recently gained interest as a material of choice for soft and stretchable electronic circuits, thanks to their virtually infinite mechanical failure strain and high electrical conductivity. Gallium-based thin films are obtained by deposi ...

A novel microfabrication platform for hybrid multilayer MEMS

Nahid Hosseini

In Atomic force microscopy (AFM), the tip-sample interaction force can be measured through two primary detection techniques: optical beam detection (OBD) and electrical (self-sensing) readout. Compared to the optical method, the convenience of the self-sen ...

High-performance nanowire-based E-mode Power GaN MOSHEMTs with large workfunction gate metal

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Minghua Zhu

In this work, we demonstrate high-performance Enhancement-mode (E-mode) GaN Metal-Oxide-Semiconductor High Electron Mobility Transistors (MOS-HEMTs) on Si substrate based on sidewall depletion achieved by nanostructured gate with large work-function metal. ...

Active Posts in Deterministic Lateral Displacement Devices

Carlotta Guiducci, Kevin Keim

Using electrically connected metal-coated posts in a deterministic lateral displacement (DLD) device and applying electric fields, electrokinetics is used to tune separations, significantly decrease the critical size for separation, and increase the dynami ...

A Generalized Index for Static Voltage Stability of Unbalanced Polyphase Power Systems including Thévenin Equivalents and Polynomial Models

Mario Paolone, Andreas Martin Kettner

This paper proposes a Voltage Stability Index (VSI) suitable for unbalanced polyphase power systems. To this end, the grid is represented by a polyphase multiport network model (i.e., hybrid parameters), and the aggregate behavior of the devices in each no ...

Collective behavior of red blood cells in confined channels

Ignacio Pagonabarraga Mora

We study the flow properties of red blood cells in confined channels, when the channel width is comparable to the cell size. We focus on the case of intermediate concentrations when hydrodynamic interactions between cells play a dominant role. This regime ...

A 10b SAR ADC with Widely Scalable Sampling Rate and AGC Amplifier Front-End

Seyed Armin Tajalli, Yusuf Leblebici, Firat Çelik, Ayça Akkaya

This paper presents a low power successive approximation register (SAR) ADC and its front-end automatic gain control (AGC) amplifier designed in 65nm CMOS technology. Digitally controlled variable gain amplifier (VGA) in AGC loop is used to maximize the dy ...

Thermal mechanical analyses of the mm-wave miter bend for the ITER electron cyclotron upper launcher first confinement system

Timothy Goodman, René Chavan, Jean-Daniel Landis, Matteo Vagnoni, Avelino Mas Sanchez, Florian Ramseyer

Each of the 4 ITER Electron Cyclotron Heating Upper Launcher (ECHUL) features 8 transmission lines used to inject microwave power of up to 1.31 MW (at the source) per line, into the plasma at 170 GHz. The microwaves are guided from the gyrotrons via (empty ...

Alkali Silica Reaction and Sulfate Attack: Expansion of Limestone Calcined Clay Cement

Karen Scrivener, Aurélie Rosine Favier

In this paper, two durability issues: Alkali Silica Reaction (ASR) and external sulfate attack were studied. The results of expansion were presented for a Normal Portland cement and a blended cement LC3 containing calcined clay and limestone as supplementa ...

Duct modes damping through an adjustable electroacoustic liner under grazing incidence

Hervé Lissek, Romain Boulandet, Gaël Matten

This paper deals with active sound attenuation in lined ducts with flow and its application to duct modes damping in aircraft engine nacelles. It presents an active lining concept based on an arrangement of electroacoustic absorbers flush mounted in the du ...
