Towards Reliable Broadcasting using ACKs

Patrick Thiran, Christina Fragouli, Mathilde Durvy

We propose a mechanism for reliable broadcasting in wireless networks, that consists of two components: a method for bandwidth efficient acknowledgment collection, and a coding scheme that uses acknowledgments. Our approach combines ideas from network codi ...

Alignment of hydrogen-related defect levels at the Si-SiO2 interface

Alfredo Pasquarello, Audrius Alkauskas

We propose a method within density functional theory for aligning defect energy levels at interfaces without relying on experimental data. We apply our scheme to the alignment of charge transition levels of the interstitial hydrogen and the hydrogen bridge ...

A semi-implicit approach for fluid-structure interaction based on an algebraic fractional step method

Alfio Quarteroni, Annalisa Quaini

We address the numerical simulation of fluid-structure interaction problems characterized by a strong added-mass effect. We propose a semi-implicit coupling scheme based on an algebraic fractional-step method. The basic idea of a semi-implicit scheme consi ...

Discriminative Cue Integration for Medical Image Annotation

Barbara Caputo, Tatiana Tommasi

Automatic annotation of medical images is an increasingly important tool for physicians in their daily activity. Hospitals produce nowadays an increasing amount of data. Manual annotation is very costly and prone to human mistakes. This paper proposes a mu ...

Rateless coding with partial CSI at the decoder

Michael Christoph Gastpar

A channel model for channels with unknown state and partial state information available causally at the decoder is proposed. The model is based on arbitrarily varying channels (AVCs), and the partial state information is characterized by allowing the decod ...

Variable length coding over an unknown channel

Emre Telatar, Aslan Tchamkerten

Burnashev in 1976 gave an exact expression for the reliability function of a discrete memoryless channel (DMC) with noiseless feedback. A coding scheme that achieves this exponent needs, in general, to know the statistics of the channel. Suppose now that t ...

Burrows-Wheeler text compression with fountain codes

Mohammad Amin Shokrollahi, Bertrand Ndzana Ndzana

This paper presents an algorithm in a purely lossless text compression setting based on fountain codes and the Burrows-Wheeler transform (BWT). The scheme consists of five stages, each of which is briefly described in the paper. The algorithm offers encour ...

Product Code Optimization for Determinate State LDPC Decoding in Robust Image Transmission

Nikolaos Thomos

We propose a novel scheme for error resilient image transmission. The proposed scheme employs a product coder consisting of LDPC codes and RS codes in order to deal effectively with bit errors. The efficiency of the proposed scheme is based on the exploita ...
