Structural Measures as Guides to Ultrastable States in Overjammed Packings

Sangwoo Kim

Jammed, disordered packings of given sets of particles possess a multitude of equilibrium states with different mechanical properties. Identifying and constructing desired states, e.g., of superior stability, is a complex task. Here, we show that in two-di ...

Assessing the energy potential of modernizing the European hydropower fleet

Anton Schleiss, Elena Vagnoni

About 50% of all hydropower plants (HPPs) worldwide were originally commissioned more than 40 years ago, so that the advanced age of the fleet is a major concern across all continents, and especially in Europe. The modernization of HPPs can generate severa ...

Design of a set of indicators suitable to help decision-making on energy strategies for Cuba

Heydi Contreras Peraza

The goal of this Master thesis project was to design a methodology that helps to analyze a set of indicators that can support the decision-making process, by identifying energy strategies with a temporal horizon 2030-2050 in Cuba. Several sources of data a ...

Balancing hydropeaking mitigation and hydropower production

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Mathieu Pierre Guy Barnoud

Around 60% of Switzerland’s power production is provided by hydropower. Despite its numerous advantages, the high fluctuations in turbined discharges cause hydropeaking at downstream rivers. Due to the environmental impacts of hydropeaking on fauna and flo ...

Systematic Integration of Energy-Optimal Buildings With District Networks

François Maréchal, Luc Girardin, Ivan Daniel Kantor, Paul Michael Stadler, Raluca-Ancuta Suciu

The residential sector accounts for a large share of worldwide energy consumption, yet is difficult to characterise, since consumption profiles depend on several factors from geographical location to individual building occupant behaviour. Given this diffi ...

RANS computations for identification of 1-D cavitation model parameters: application to full load cavitation vortex rope

François Avellan, Christophe Nicolet, Andres Müller, Sébastien Alligné

Due to the massive penetration of alternative renewable energies, hydropower is a key energy conversion technology for stabilizing the electrical power network by using hydraulic machines at off design operating conditions. At full load, the axisymmetric c ...

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. ...
