In 1971, the first microprocessor produced in mass production had 2300 transistor and was able to compute 60'000 operations per second at 740 kHz. Nowadays, even a common gaming console uses a central unit including 243 millions of transistors running at 4 ...
In this paper we address the problem of multi-object tracking in video sequences, with application to pedestrian tracking in a crowd. In this con- text, particle ¯lters provide a robust tracking framework under ambiguity conditions. The particle ¯lter tech ...
Regularization networks are nonparametric estimators obtained from the application of Tychonov regularization or Bayes estimation to the hypersurface reconstruction problem. With the usual algorithm, the computation of the weights scales as O(n3) where ...
Obstruction-free implementations of concurrent ob jects are optimized for the common case where there is no step contention, and were recently advocated as a solution to the costs associated with synchronization without locks. In this paper, we study this ...
A shared memory abstraction can be robustly emulated over an asynchronous message passing system where any process can fail by crashing and possibly recover (crash-recovery model), by having (a) the processes exchange messages to synchronize their read and ...
Most people believe that renaming is easy: simply choose a name \emph{at random}; if more than one process selects the same name, then try again. We highlight the issues that occur when trying to implement such a scheme and shed new light on the read-write ...
We consider the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest. We motivate and propose new versions of the diffusion LMS algorithm, including a version that outperforms previous sol ...
The increasing complexity of nowadays applications has lead to the need of more and more intensive specification and validation tasks by means of software implementations. Besides, as the complexity grows, it is becoming very hard to understand the specifi ...
In this thesis, we address different aspects of the airline scheduling problem. The main difficulty in this field lies in the combinatorial complexity of the problems. Furthermore, as airline schedules are often faced with perturbations called disruptions ...
A new approach for inserting repeaters in 3-D interconnects is proposed. The allocation of repeaters along an interplane interconnect is iteratively determined. The proposed approach is compared with two other techniques based on conventional methods used ...
