Fast Object Detection with Entropy-Driven Evaluation

Pascal Fua, François Fleuret, Raphael Sznitman, Carlos Joaquin Becker

Cascade-style approaches to implementing ensemble classifiers can deliver significant speed-ups at test time. While highly effective, they remain challenging to tune and their overall performance depends on the availability of large validation sets to esti ...

Heated membranes for stencil lithography application

Sahbi Boujnah

This project aims to improve the technique of self-cleaning stencil based on heated membranes and minimize the clogging of stencil’s apertures. To this end, theory on vapor condensation has been developed for Aluminum, Chromium, Titanium, Gold and Platinum ...

Quantum-coherent coupling of a mechanical oscillator to an optical cavity mode

Tobias Kippenberg, Albert Schliesser, Stefan Alexander Weis

Optical laser fields have been widely used to achieve quantum control over the motional and internal degrees of freedom of atoms and ions(1,2), molecules and atomic gases. A route to controlling the quantum states of macroscopic mechanical oscillators in a ...

Heat Transfer between the Superconducting Cables of the LHC Accelerator Magnets and the Superfluid Helium Bath

Pier Paolo Granieri

In this thesis work we investigate the heat transfer through the electrical insulation of superconducting cables cooled by super fluid helium. The cable insulation constitutes the most severe barrier for heat extraction from the superconducting magnets of ...

Methods for determination of degree of reaction of slag in blended cement pastes

Karen Scrivener, Emmanuel Gallucci, Vanessa Kocaba

To measure the degree of reaction of slag in blended pastes, five methods were studied. Selective dissolution and differential scanning calorimetry are shown to be unreliable, SEM-BSE-IA-mapping is time consuming, but does provide good results with a reaso ...

Thermoeconomic Analysis of a Solar Enhanced Energy Storage Concept Based on Thermodynamic Cycles

Samuel Henchoz

Large scale energy storage may play an increasingly important role in the power generation and distribution sector, especially when large shares of renewable energies will have to be integrated into the electrical grid. Up to now pumped-hydro is the only t ...

Data-based identification of a parametric heat pump model

Franca Schmid

At the LENI a heat pump model has been developed, which aims to simulate a single state compression heat pump in both steady state and transient regime. For gaining the experimental data and for the simulation the same set of input data is used. The goal i ...

A standardization of the coefficient of performance for magnetic refrigerators, heat pumps and energy conversion machines

Didier Albert Simon Vuarnoz, Cyrill Gonin

Publications on magnetocaloric materials, magnetic refrigerators, magnetic heat pumps and magnetic power conversion machines contain experimental results as well as solutions obtained by physical modelling, analytical and numerical calculations. Whereas ma ...

Granular Thermodynamics

Pedro Miguel Nunes Pereira de Almeida Reis

We present experimental evidence for a strong analogy between quasi‐2D uniform non‐equilibrium steady states (NESS) of excited granular materials and equilibrium thermodynamics. Under isochoric conditions we find that the structure of granular NESS, as mea ...
