LT-codes are a new class of codes introduced by Luby for the purpose of scalable and fault-tolerant distribution of data over computer networks. In this paper, we introduce Raptor codes, an extension of LT-codes with linear time encoding and decoding. We w ...
Concurrency and failures are fundamental problems in distributed computing. One likes to think that the mechanisms needed to address these problems can be separated from the rest of the distributed application: in modern words, these mechanisms could be as ...

(short version) Constraint satisfaction is the most successful computational paradigm for problem-solving today. A major difficulty is efficient formulation of constraint satisfaction proiblems (CSP). This thesis describes several methods for abstractions ...
We give a comparison of the performance of the recently proposed torus-based public key cryptosystem CEILIDH, and XTR. Underpinning both systems is the mathematics of the two dimensional algebraic torus T6(Fp). However, while they both attain ...
Today's video codecs employ motion compensated prediction in combination with block matching techniques. These techniques, although achieving some level of adaptivity in their latest versions, continue to rely on the decomposition of frames on a set of art ...
The context of this paper is Enterprise Architecture (EA). EA is a multi-disciplinary approach that allows dierent specialists to design new business and IT systems and focuses on the integration of these systems. Our group develops a specic EA method that ...
This thesis introduces a new implementation of the LAIO api, liblaiogen. LAIO stands for Lazy Asynchronous I/O. It is an api for performing asynchronous I/O. Among several benefits, one of the most important is that LAIO is lazy, in the sense that it creat ...
The PROSITE database consists of a large collection of biologically meaningful signatures that are described as patterns or profiles. Each signature is linked to documentation that provides useful biological information on the protein family, domain or fun ...
Sequential consistency and causal consistency constitute two of the main consistency criteria used to define the semantics of accesses in the shared memory model. An execution is sequentially consistent if all processes can agree on a same legal sequential ...
