Stable blow up dynamics for energy supercritical wave equations

We study the semilinear wave equation

\displaystyle \partial _t^2 \psi -\Delta \psi =\vert\psi \vert^{p-1}\psi

for

p > 3

with radial data in three spatial dimensions. There exists an explicit solution which blows up at

Effects of soil thermo-plasticity on energy piles

Lyesse Laloui, Fabrice Dupray, Alice Di Donna

Energy geostructures are spreading rapidly in Europe and all around the world. They represent a renewable and clean source of energy which can be used for heating and cooling of buildings, infrastructures and all kind of environment. This technology couple ...

Numerical study of the heating-cooling effects on the geotechnical behaviour of energy piles.

Lyesse Laloui, Fabrice Dupray, Alice Di Donna

Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...

Simulation of Urban Energy Flow: A Graph Theory Inspired Approach

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Diane Perez

Following the increased consciousness regarding global warming and other environmental issues, there is a growing urge in cities for a more rational energy supply and use in buildings. In parallel, the range of possible actions has broaden, from building r ...

A codimension two stable manifold of near soliton equivariant wave maps

Joachim Krieger, Daniel Tataru

We consider finite-energy equivariant solutions for the wave map problem from ℝ2+1 to S2 which are close to the soliton family. We prove asymptotic orbital stability for a codimension-two class of initial data which is small with respect to a stronger topo ...

Global dynamics away from the ground state for the energy-critical nonlinear wave equation

Joachim Krieger

We study global behavior of radial solutions for the nonlinear wave equation with the focusing energy critical nonlinearity in three and five space dimensions. Assuming that the solution has energy at most slightly more than the ground states and gets away ...

Analysis Of An Energy-Based Atomistic/Continuum Approximation Of A Vacancy In The 2D Triangular Lattice

We present an a priori error analysis of a practical energy based atomistic/continuum coupling method (A. V. Shapeev, Multiscale Model. Simul., 9(3): 905-932, 2011) in two dimensions, for finite-range pair-potential interactions, in the presence of vacancy ...

Fluent coordination of autonomous vehicles at intersections

Denis Gillet, Laleh Makarem

In this paper we introduce a new decentralized navigation function for coordination of autonomous vehicles at intersections. The main contribution is a navigation function designed for vehicles with predefined paths that uses expected time to intersection ...

On the Adaptation of Building Controls to the Envelope and the Occupants

David Daum

The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...

Process design methods for sustainable energy systems

François Maréchal

Today, energy is the driver of the modern society, allowing for transforming raw materials and resources into ``useful'' products and services. Concerns on climate change and resources scarcity together with the increasing importance put on the environment ...
