Multipolar effects and strong coupling in hybrid plasmonic metamaterials

Recently stacked metamaterial structures coupled to a conductive plane have been investigated and have been shown to exhibit the same properties as stacked structures with double the layers, due to dipole mirror coupling. Here we study a system of stacked ...

Cr-poisoning in (La,Sr)(Co,Fe)O-3 cathodes after 10,000 h SOFC stack testing

Jan Van Herle, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler

After 10,000 h solid oxide fuel cell (SOFC) stack operation, the Cr-poisoning situation in (La0.6Sr0.4) (Co0.2Fe0.8)O-3 (LSCF)-based cathode material is depicted in this work. Systematic Cr profiling by energy-dispersive X-ray spectroscopy (EDS), from post ...

Experimental Real-Time Optimization of a Solid Oxide Fuel Cell Stack via Constraint Adaptation

Dominique Bonvin, Grégory François, Zacharie Wuillemin, Arata Nakajo, Gene Bunin, Leonidas Tsikonis

The experimental validation of a real-time optimization (RTO) strategy for the optimal operation of a solid oxide fuel cell (SOFC) stack is reported in this paper. Unlike many existing studies, the RTO approach presented here utilizes the constraint-adapta ...

In-situ grown horizontal carbon nanotube membrane

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We present the successful fabrication of horizontally grown and dense carbon nanotube (CNT) membranes in situ. A TiN/Al2O3/TiN stack is first patterned to be employed as a support for the CNT growth. Iron is then evaporated with a 45 degrees tilt angle on ...

S2E: A Platform for In-Vivo Multi-Path Analysis of Software Systems

George Candea, Vitaly Chipounov, Volodymyr Kuznetsov

This paper presents S2E, a platform for analyzing the properties and behavior of software systems. We demonstrate S2E's use in developing practical tools for comprehensive performance profiling, reverse engineering of proprietary software, and bug finding ...

Significance Driven Computation on Next-Generation Unreliable Platforms

Vaibhav Gupta, Georgios Karakonstantis

In this paper, we propose a design paradigm for energy efficient and variation-aware operation of next-generation multicore heterogeneous platforms. The main idea behind the proposed approach lies on the observation that not all operations are equally impo ...

Querypoint : Moving Backwards on Wrong Values in the Buggy Execution

Claude Petitpierre, Salman Mirghasemi

As developers debug, they often have to seek the origins of wrong values they see in their debugger. This search must be performed backwards in time since the code causing the wrong value is executed before the wrong value appears. Therefore, locating the ...

Debugging by lastChange

Claude Petitpierre, Salman Mirghasemi

Developers often seek the origins of wrong values they see in their debugger. Their search must be backwards in time: the code causing the wrong value executed before the wrong value appeared. Searching with breakpoint- or log- based debuggers demands pers ...

Ultra-low pressure sensor for neonatal resuscitator

Peter Ryser, Thomas Maeder, Caroline Jacq, Nicolas Craquelin, Enrico Haemmerle

In this work, we study in detail the sensing characteristics of piezoresistive force sensors based on structured LTCC (Low Temperature Co-fired Ceramic) cantilevers carrying a thick-film piezoresistive bridge. These devices show much improved sensitivity c ...
