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 ...
We discuss the scheme rind test performances of this recently commissioned system in its final configuration. The tests show that the improvements in the electron optics system with respect to other instruments in the same class made it possible to reach l ...
We propose a novel approach to point matching under large viewpoint and illumination changes that is suitable for accurate object pose estimation at a much lower computational cost than state-of-the-art methods. Most of these methods rely either on using a ...
MycDB is an integrated mycobacterial database. This means that it contains information on all aspects of mycobacteria, whether immunology, metabolism, or the researchers working on mycobacteria. For historical reasons, the starting point has been molecular ...
For a class of sensor networks, the task is to monitor an underlying
physical phenomenon over space and time through a
noisy observation process. The sensors can communicate back
to a data collector over a noisy channel. The key parameters
in such a se ...

In earlier work, we proposed treating wide baseline matching of feature points as a classification problem, in which each class corresponds to the set of all possible views of such a point. We used a K-mean plus Nearest Neighbor classifier to validate our ...
Using arguments developed by De Giorgi in the 1950's, it is possible to prove the regularity of the solutions to a vast class of variational problems in the Euclidean space. The main goal of the present thesis is to extend these results to the more abstrac ...
This paper exhibits a class of universal Raptor codes: for a given integer k, and any real /spl epsiv/>0, Raptor codes in this class produce a potentially infinite stream of symbols such that any subset of symbols of size k(1 + /spl epsiv/) is sufficient t ...
In this paper, we consider the class of adaptive filters with error nonlinearities. In particular, we derive an expression for the optimum nonlinearity that minimizes the steady-state error and attains the limit mandated by the Cramer-Rae bound of the unde ...
The postgraduate course for construction management and economics at the Swiss Federal Institute of Technology in Lausanne is an e-learning course for architects and civil engineers. The students are mostly fulltime employees, who put a strong emphasis on ...
