An Indicator-Based Approach for Analysing the Resilience of Transitions for Energy Regions. Part II: Empirical Application to the Case of Weiz-Gleisdorf, Austria

Claudia Rebeca Binder Signer, Romano Tobias Wyss, Susan Marie Mühlemeier

In this paper, we apply an indicator-based approach to measure the resilience of energy regions in transition to a case study region in Austria. The indicator-based approach allows to determine the resilience of the transition of regional energy systems to ...

Combined Exergy Analysis and Energy Integration for the Optimization of Nitrogen Fertilizer Plants

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the enthalpy of reaction released by the exothermic chemical systems. However, to fully supply the exergy demands of the highl ...

Exergy assessment of future energy transition scenarios with application to Switzerland

François Maréchal, Daniel Favrat, François Richard Vuille, Victor Codina Gironès, Matteo Allais

Using an exergy based indicator is highly desirable to compare future national energy strategies. A new web- based information platform called energyscope.ch, informing the general public on the Swiss energy transition was presented at ECOS2016. This paper ...

Estimating the potential for thermal load management in buildings at a large scale: overcoming challenges towards a replicable methodology

François Maréchal, Araz Ashouri, Solène Goy

A large share of the energy is consumed in buildings but at the individual scale, the energy consumption is rarely optimized; as a consequence, energy is wasted, electricity consumption is characterized by peaks and renewable energy integration is hindered ...

Real-Time Control of Microgrids with Explicit Power Setpoints: Unintentional Islanding

Jean-Yves Le Boudec, Mario Paolone, Lorenzo Enrique Reyes Chamorro, Andrey Bernstein

The invention provides a method for coping with an unintentional islanding of an electrical distribution grid within a Commelec-type framework for the real-time control of micro-grids, of Resource Agents (RA) controlled by Grid Agents (GA), comprising at l ...

Global well-posedness for the Yang-Mills equation in 4+1 dimensions: Small energy

Joachim Krieger, Daniel Tataru

We consider the hyperbolic Yang-Mills equation on the Minkowski space

\reels^{4+1}

. Our main result asserts that this problem is globally well-posed for all initial data whose energy is sufficiently small. This solves a longstanding open problem. ...

数字化图解静力学设计方法 — 建筑师和结构工程师共享的设计工具 (Digital Graphic Statics – Shared Design Tools for Architects and Engineers)

Corentin Jean Dominique Fivet

Aware of its heavy environmental impact, the construction industry is on the lookout for new tools that provide a closer control of the end performance of buildings, e.g. the energy and volume of materials that they demand and their ability to be repaired ...

An Inexact Ultra-low Power Bio-signal Processing Architecture With Lightweight Error Recovery

David Atienza Alonso, Giovanni Ansaloni, Ruben Braojos Lopez, Soumya Subhra Basu, Loris Gérard Duch

The energy efficiency of digital architectures is tightly linked to the voltage level (Vdd) at which they operate. Aggressive voltage scaling is therefore mandatory when ultra-low power processing is required. Nonetheless, the lowest admissible Vdd is oe ...

Shock waves from nonspherical cavitation bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Outi Supponen, Marc Tinguely

We present detailed observations of the shock waves emitted at the collapse of single cavitation bubbles using simultaneous time-resolved shadowgraphy and hydrophone pressure measurements. The geometry of the bubbles is systematically varied from spherical ...
