Single-Photon Synchronous Detection

Edoardo Charbon, Ties Jan Henderikus Kluter, Cristiano Niclass, Claudio Favi, Frédéric Monnier

Phase and intensity of light are detected simultaneously using a fully digital imaging technique: single-photon synchronous detection. This approach has been theoretically and experimentally investigated in this paper. We designed a fully integrated camera ...

Analisi dell'impatto della mobilità individuale in Ticino

Cecilia Matasci

Personal mobility carries a heavy environmental burden. This is particularly true for Switzerland, where it is responsible for 33% of energy consumption and for 34% of CO2 emissions1 [1]. The impact is however not equally distributed between the different ...

Energy System Analysis of a University Campus

The goal of this Diploma Thesis is to deliver an integrated view on EPFL as an energy system. It shall support future decision making about further steps towards increased sustainability and efficiency at EPFL, regarding the energy system. The results of t ...

Microfluidic chip for cells' electrofusion

Albora De Pablo Pena

[...] During this project, the fusion feasibility of chips produced for other applications have been tested and some critical fusion parameters have been defined. Then, with the help of FEM simulations, a new chip design has been proposed to overcome the p ...

Low Cost Earth Sensor Based on Oxygen Airglow (AIRES)

Edoardo Charbon, Herbert Shea, Noémy Scheidegger

This project has demonstrated the feasibility of a low-cost Earth sensor based on imaging oxygen airglow, allowing 0.4° accuracy from GEO under any illumination condition. Available Earth Sensor (ES) are based on the measurement of the earth’s infrared rad ...

Bioinspired Vision-based Microflyers

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

We aim at developing vision-based controllers for microyers capable of ying autonomously in indoor environments. Although signicant advances have been made in this domain over the past decade, only subproblems have been successfully addressed (for example ...

The challenge of introducing an exergy indicator in a local low on energy

François Maréchal, Daniel Favrat

Extending the idea of exergy to practitioners and policy makers is still a major challenge. Recently the "Canton of Geneva" in Switzerland introduced a new law governing the procedures of attribution of building permits for new or retrofitted city areas. A ...

RADIACONF : A design tool for locating and sizing radiant panels to improve comfort

Claude-Alain Roulet

Thermal comfort depends on heat exchanges of the body by conduction evapo-transpiration and convection to the air, and radiation to and from surrounding surfaces. Usual ways of sizing heating and cooling systems are based on homogeneous temperature in the ...

Neurobat, a Predictive and Adaptive Heating Control System Using Artificial Neural Networks

Manuel Bauer, Nicolas Morel

The paper describes a predictive and adaptive heating controller, using artificial neural networks to allow the adaptation of the control model to the real conditions (climate, building characteristics, user's behaviour). The controller algorithm has been ...

Gestion biomimétique de l'énergie dans le bâtiment

Manuel Bauer

The efficient thermal control of buildings is a complex problem. Non controlled perturbations like user behaviour and meteorological conditions can change much with time and make this task difficult. This work proposes considering the building as a 'living ...
