Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Fabrication of epoxy spherical microstructures by controlled drop-on-demand inkjet printing

Jürgen Brugger, Rosario Maurizio Gullo, Loïc Jacot-Descombes

Well-controlled spherical microstructures open new possibilities for several MEMS devices, such as hemispherical microfluidic channels or micro-optical elements. However, machining of micro-spherical shapes has proven to be difficult with conventional plan ...

Intra-cavity patterning for mode control in 1.3μm coupled VCSEL arrays

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Lukas Mutter

We report coupled VCSEL arrays, emitting at 1.3μm wavelength, in which both the optical gain/loss and refractive index distributions were defined on different vertical layers. The arrays were electrically pumped through a patterned tunnel junction, whereas ...

Array-Code Ensembles -or- Two-Dimensional LDPC Codes

Mohammad Amin Shokrollahi, Yuval Cassuto

Probabilistic construction of codes on two-dimensional arrays is proposed and analyzed. Instead of a pure combinatorial erasure model used in traditional array codes, we propose a mixed combinatorial-probabilistic model of limiting the number of column fai ...

Dictionary Identification - Sparse Matrix-Factorisation via $\ell_1$-Minimisation

Rémi Gribonval, Karin Schnass

This article treats the problem of learning a dictionary providing sparse representations for a given signal class, via

\ell_1

-minimisation. The problem can also be seen as factorising a

\ddim \times \nsig

matrix $Y=(y_1 \ldots y_\nsig), , y_n\in \R^\ ...

3D Nanostructured Silicon Relying on Hard Mask Engineering for High Temperature Annealing (HME-HTA) Processes for Electronic Devices

Mihai Adrian Ionescu, Matthieu Bopp

Annealing silicon at high temperatures in hydrogen ambiance has been reported to induce surface diffusion of silicon; in these conditions, adapted 2D arrays of trenches etched in Bulk Si are transformed into buried cavities creating suspended membranes. A ...

Symmetry, XPD, and port isolation in an ACMPA array with dual linear polarization

Roberto Torres Sánchez

Aperture coupled microstrip patch antennas (ACMPA) are very convenient array elements for designing high directivity planar antennas. Dual polarization ACMPA arrays for Direct Broadcasting Services (DBS) have the problems of low cross-polar discrimination ...

Efficient Distributed Subtyping Tests

Rachid Guerraoui, João Barreto, Patrick Eugster

Subtyping tests are essential in typed publish/subscribe infrastructures, especially when the underlying programming language supports subtype conformance, as in Java or C#. These tests are particularly challenging when the publish/subscribe infrastructure ...

Fabrication of large-area ordered arrays of nanoparticles on patterned substrates

Heinrich Hofmann, Paul Bowen, Frédéric Juillerat

Many potential applications in nanotechnology require virtually defect-free arrays of nanometre-scale particles over large areas. Guided self-assembly of colloidal particles on patterned templates has been shown to produce ordered arrays of colloidal parti ...

Full-field laser Doppler perfusion imaging and monitoring with an intelligent CMOS camera

Theo Lasser

A system for full-field laser Doppler blood flow imaging has been developed and tested on biomedical samples. The new imaging system allows 2D flow maps or monitoring flux signals to be obtained from a plurality of measured points simultaneously by using a ...
