Semi-global controllability of a geometric wave equation

We prove the semi-global controllability and stabilization of the

Geomechanics for Energy and the Environment: Current Developments

Lyesse Laloui, Roba Houhou

Geomechanics is advancing our understanding of the multi-physical processes encountered in engineering practices involving energy storage and production and environmental protection for which the characterization of the behavior of relevant materials is es ...

Where is the money ? A decomposition of monetary flows behind fossil fuels

François Maréchal, Jonas Schnidrig, Xiang Li, Raphaël Briguet

Transition from fossils to renewables is leading to radical societal changes. Shifting the capital from fossils to renewables is commonly accompanied with political concerns, such as energy autonomy, domestic employment etc. Despite a decreasing trend in r ...

Energy Bounds For A Fourth-Order Equation In Low Dimensions Related To Wave Maps

Tobias Johannes Schmid

For compact, isometrically embedded Riemannian manifolds N -> R-L, we introduce a fourth-order version of the wave maps equation. By energy estimates, we prove an a priori estimate for smooth local solutions in the energy subcritical dimension n = 1, 2. Th ...

On the scale dependence in the dynamics of frictional rupture: Constant fracture energy versus size-dependent breakdown work

Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, François Xavier Thibault Passelègue, Fabian Barras, Federica Paglialunga

Potential energy stored during the inter-seismic period by tectonic loading around faults is released during earthquakes as radiated energy, frictional dissipation and fracture energy. The latter is of first importance since it is expected to control the n ...

A Ribbon Model for Nematic Polymer Networks

Harmeet Singh

We present a theory of deformation of ribbons made of nematic polymer networks (NPNs). These materials exhibit properties of rubber and nematic liquid crystals, and can be activated by external stimuli of heat and light. A two-dimensional energy for a shee ...

Spatio-Temporal Estimation of Renewable Energy Potential in Built Environments using Big Data

Alina Ursula Rosa Walch

To achieve the goals of the Paris Agreement on climate change, governments around the world must shift to renewable energy (RE) to drastically reduce their CO2 emissions within the next 10-30 years. The development of effective strategies for RE integratio ...

Contribution of storage technologies to renewable energy hubs

A holistic approach, considering all the energy needs of a territory, should be adopted in the challenge of the energy transition. Synergies between the different end-use demand sectors must be developed, in order to optimize the efficient use of resources ...

Towards a negative-emission society

Xiang Li

Negative carbon emissions are proved necessary to limit global temperature increase below 1.5C compared to pre-industrial levels. (a) Reducing carbon sources and (b) increasing negative emissions are two effective ways to achieve this goal. (a) involves th ...

A systematic framework for the multi-time integration of industrial complexes and urban systems

François Maréchal, Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

The energy integration of industrial complexes and urban agglomerations has many benefits in terms of rational energy use and reduced environmental impact, especially during scenarios of supply chain uncertainty and volatile market prices. In fact, the div ...
