On the slip burst amplitude cutoff in dislocation-rich microcrystals

The plastic deformation of small-scale face-centered cubic metals exhibits intermittent slip burst events that appear on stress-strain curves as sudden strain jumps and/or load drops. These events are generally attributed to the avalanche-like cooperative ...

Multi-Objective Optimization of Grooved Gas Journal Bearings for Robustness in Manufacturing Tolerances

Jürg Alexander Schiffmann, Eliott Philippe Guenat

A tolerancing method highlighting trade-offs against key design variables of mechanical systems is proposed and applied to herringbone-grooved gas journal bearings. Gas bearings typically suffer from a subsynchronous instability, demanding a very tight tol ...

1200 V Multi-Channel Power Devices with 2.8 Ω•mm ON-Resistance

Elison de Nazareth Matioli, Jun Ma, Catherine Erine, Minghua Zhu, Kai Cheng

Here we report novel multi-channel AlGaN/GaN MOSHEMTs with high breakdown voltage (V BR ) and low ON-resistance (R ON ). The multi-channel structure was judiciously designed to yield a small sheet resistance (R s ) of 80 Ω/sq using only four 2DEG channels, ...

STEP-NC compliant process planning of additive manufacturing: remanufacturing

Ian Anthony Stroud, Jumyung Um

Additive manufacturing is becoming one of the key methods for reproducing repair sections in remanufacturing processes. The major advantage of using additive processes is to minimize production time and waste. However, the surface quality and shape accurac ...

A Robust Capacitive Digital Read-Out Circuit for a Scalable Tactile Skin

Sandro Carrara, Danilo Demarchi

This paper presents a robust, capacitive digital read-out circuit (ROC) for sensitive skin applications in humanoid robots. The ROC can be calibrated to null the parasitic effects of transducer variation due to physical assembly. A prototype is fabricated ...

The DEMO wall load challenge

Ambrogio Fasoli, Jonathan Graves, Jan Horacek, David Pfefferlé, Samuel Lanthaler, Bernhard Sieglin, Hartmut Zohm

For several reasons the challenge to keep the loads to the first wall within engineering limits is substantially higher in DEMO compared to ITER. Therefore the pre-conceptual design development for DEMO that is currently ongoing in Europe needs to be based ...

Light confinement effect of non-spherical nanoscale solid immersion lenses

Hans Peter Herzig, Gaël David Osowiecki, Toralf Scharf, Myun Sik Kim

We report on the light confinement effect observed in nonideally shaped (i.e., nonspherical) nanoscale solid immersion lenses (SIL). To investigate this effect, nanostructures of various shapes are fabricated by electron-beam lithography. When completely m ...

SMD pressure and flow sensors for industrial compressed air in LTCC technology

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Grégoire Boutinard Rouelle

In this work, we propose an SMD (surface mount device) pressure sensor in LTCC technology specially designed for standard industrial compressed air. It combines the measurement of pressure and temperature, with its integrated signal conditioning electronic ...
