Fabrication of Polymer-Based Micro Devices: Formulation and Study of the Paste

Peter Ryser, Thomas Maeder, Nathalie Sophie Adeline Serra, Olivier Gentsch

We investigate in the present work the fabrication of polymer-based micro-fluidic and micro-mechanical devices using sacrificial, resistive/conductive pastes, through a screen-printing process. An organic sacrificial paste is first screen-printed onto a su ...

Hyper-DEMIX: Blind Source Separation of Hyperspectral Images Using Local ML Estimates

We propose a new method to unmix hyperspectral images. Our method exploits the structure of the material abundance maps by assuming that in some regions of the spatial dimension, only one material is present. Such regions provide a local estimate of the en ...

A Class of Transformations that Polarize Binary-Input Memory less Channels

Satish Babu Korada, Eren Sasoglu

A generalization of Arikan's polar code construction using transformations of the form G(circle times n) where G is an l x l matrix is considered. Necessary and sufficient conditions are given for these transformations to ensure channel polarization. It is ...

Secure Communication using an Untrusted Relay via Sources and Channels

Michael Christoph Gastpar

Confidential communication aided by a relay without security clearance is studied. General strategies and outer bounds are derived for the problem of secret communication and secret key generation when correlated observations at all terminals are available ...

Atoms of all channels, unite! Average case analysis of multi-channel sparse recovery using greedy algorithms

Pierre Vandergheynst, Rémi Gribonval, Karin Schnass

This paper provides new results on computing simultaneous sparse approximations of multichannel signals over redundant dictionaries using two greedy algorithms. The first one, p-thresholding, selects the S atoms that have the largest

Mechanical control of fluids in micro-analytical devices

Hubert Girault, Joël Rossier, Xiaoxia Bai

An apparatus for manipulating fluid samples comprises a micro-chip device having first and second covered channels, each channel having openings at both ends. The channels intersect to form a common intersection. Three of the openings of the channels are c ...
