Thermal conductivity of Al-SiC composites with monomodal and bimodal particle size distribution

The thermal conductivity of aluminum matrix composites having a high volume fraction of SiC particles is investigated by comparing data for composites fabricated by infiltrating liquid aluminum into preforms made either from a single particle size, or by m ...

Design, fabrication, and characterization of a composite scaffold for bone tissue engineering

Melody Swartz, Alice Anna Tomei, Federica Boschetti

Poly(lactide-co-glycolide) (PLGA) scaffolds have been successfully used in bone tissue engineering, with or without hydroxyapatite (HA) and with a macroporosity given either by simple PLGA sphere packaging and/or by leaching out NaCI. The objective of this ...

Low Rank Updates for the Cholesky Decomposition

Matthias Seeger

Usage of the Sherman-Morrison-Woodbury formula to update linear systems after low rank modifications of the system matrix is widespread in machine learning. However, it is well known that this formula can lead to serious instabilities in the presence of ro ...

Microfabrication d'objets composites fonctionnels en 3D et à haut facteur de forme, par procédés UV-LIGA et microstéréolithographie

Sébastien Jiguet

The present thesis deals with new composite photoresists for the UV-LIGA and microstereolithography microfabrication processes. The aim is to build functional 3D objects, with high aspect ratio. Two projects have been investigated in parallel for each micr ...

Application of the singular value decomposition method for inversion of interferometer measurements in fusion plasmas

Ivo Furno, Henri Weisen, Roland Behn, Emiliano Fable

We present applications of a recently developed method, the singular value decomposition inversion (SVD-I), for inverting line integrated multichannel interferometer measurements in fusion devices. The method expands the local electron density profiles int ...

On the electrical conductivity of metal matrix composites containing high volume fractions of non-conducting inclusions

Andreas Mortensen, Ludger Weber

Different predictive models-the Maxwell mean field approach, the differential effective medium scheme, the 2- and 3-phase self-consistent, and 3-point model-for the electrical conductivity of two-phase materials are assessed based on electrical conductivit ...

3D Modeling of Coupling Between Superconducting Filaments via Resistive Matrix in AC Magnetic Field

Francesco Grilli, Yong Yang, Bertrand Dutoit

The ac loss of superconducting composite depends strongly on coupling between superconducting filaments via the resistive matrix. The established technique for loss reduction using twisted filaments relies on the decoupling of the filaments below a critica ...

A fast algorithm for subspace state-space system identification via exploitation of the displacement structure

Daniel Kressner

Two recent approaches (Van Overschee, De Moor, N4SID, Automatica 30 (1) (1994) 75; Verhaegen, Int. J. Control 58(3) (1993) 555) in subspace identification problems require the computation of the R factor of the QR factorization of a block-Hankel matrix H, ...
