Fixed-order Controller Design for State Space Polytopic Systems by Convex Optimization

In this paper, a new method for fixed-order controller design of systems with polytopic uncertainty in their state space representation is proposed. The approach uses the strictly positive realness (SPRness) of some transfer functions, as a tool to decoupl ...

Energy-aware adaptive bi-Lipschitz embeddings

Volkan Cevher, Bubacarr Bah, Ali Sadeghian

We propose a dimensionality reducing matrix design based on training data with constraints on its Frobenius norm and number of rows. Our design criteria is aimed at preserving the distances between the data points in the dimensionality reduced space as muc ...

ARCHE D06 - Recommendations for the tailoring of UHPFRC recipes for rehabilitation

Emmanuel Denarié

The extremely low permeability of Ultra High Performance Fibre Reinforced Concretes (UHPFRC) associated to their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjected ...

Fast-Marching Tractography for Connection Matrix (Fast-TraC)

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet

Although high angular resolution diffusion MRI techniques are able to solve multiple intra-voxel fiber orientations, the usual streamline Diffusion Spectrum Imaging (DSI) tractography algorithms present some limitations in their ability to map complex fibe ...

Film stacking impregnation model for a novel net-shape thermoplastic composite preforming process

Véronique Michaud, Martyn Douglas Wakeman, Simon Jespersen

An impregnation model has been developed to evaluate the infiltration phenomena that occur during a novel near net shape preforming method. This process comprises automated deposition of thermoplastic resin and unidirectional (UD) carbon fibres to a pre-pr ...

Lowering the detection limit for arsenic: Implications for a future practical quantitation limit

Janet Gordon Hering

The practical quantitation limit (PCIL) for arsenic (As) is currently orders of magnitude higher than its nonenforceable, health-based standard in California. Analytical limitations caused by chloride (CO interference can be overcome using high-resolution, ...

A Two-level Computable Equilibrium Model to Assess the Strategic Allocation of Emission Allowances Within the European Union

Marc Vielle, Alain Haurie, Alain Bernard

This paper deals with the modeling of the strategic allocation of greenhouse gases emission allowances in the EU-wide trading market that results from Kyoto agreement implementation. An M-matrix game is formulated where the players are countries or groups ...

Optical properties of nano-structured materials studied by means of interferometric techniques

In this thesis work we avail ourselves of optical interferometric techniques for the study of the optical properties of nano-structured materials. As a first step, we set up a multiple heterodyne scanning probe optical microscope (MH-SPOM). This apparatus ...

Development of low-temperature thick-film materials for piezoresistive sensors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

Thick-film materials are very advantageous for piezoresistive pressure and force sensors because of ease of processing, reliability and low cost. However, their applications are restricted because standard thick-film materials require processing temperatur ...

Cell-demanded release of VEGF from synthetic, biointeractive cell ingrowth matrices for vascularized tissue growth

Matthias Lütolf, Jeffrey Alan Hubbell, Martin Ehrbar

Local, controlled induction of angiogenesis remains a challenge that limits tissue engineering approaches to replace or restore diseased tissues. We present a new class of bioactive synthetic hydrogel matrices based on poly(ethylene glycol) (PEG) and synth ...
