Swiss-EnergyScope.ch: a Platform to Widely Spread Energy Literacy and Aid Decision-Making

François Maréchal, Daniel Favrat, Stefano Moret, Victor Codina Gironès

We develop an energy calculator within an online teaching platform to aid citizens and decision-makers understanding an energy system. The model, designed in order to be easily adapted to any energy system at national or regional scale, is presented and ap ...

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 ...

Net primary energy balance of a solar-driven photoelectrochemical water-splitting device

Sophia Haussener

A fundamental requirement for a renewable energy generation technology is that it should produce more energy during its lifetime than is required to manufacture it. In this study we evaluate the primary energy requirements of a prospective renewable energy ...

Design of a contactless energy transfer system for desktop peripherals

Yves Perriard, Paolo Germano, Miroslav Markovic, Pascal Meyer

This paper presents an approach to design a contactless energy-transfer system to supply desktop computer peripherals. Energy is transferred using coreless transformers from an array of primary coils (placed on a table) to one or several secondary coils (p ...

Inelastic Scatterings and Applications to Distributed Sensing

Luc Thévenaz

Inelastic scatterings turn out to occupy an essential place in sensing applications, since they simply require a plain optical fibre as sensing element, with no special preparation. They give rise to energy and momentum transfers with the fibre material an ...
