Hyperparameter estimation for satellite image restoration using a MCMC maximum-likelihood method
The satellite image deconvolution problem is ill-posed and must be regularized. Herein, we use an edge-preserving regularization model using a ' function, involving two hyper...

Priority queueing systems: from probability generating functions to tail probabilities
Obtaining (tail) probabilities from a transform function is an important topic in queueing theory. To obtain these probabilities in discrete-time queueing systems, we have to inve...

Generalized loopy 2U: A new algorithm for approximate inference in credal networks
Credal nets generalize Bayesian nets by relaxing the requirement of precision of probabilities. Credal nets are considerably more expressive than Bayesian nets, but this makes bel...

Combining Parallel Sequence Spread Spectrum (PSSS) with OFDM - Concept and Simulation Results
—In this paper, we present a novel multi-carrier spread spectrum (MCSS) system which uses Parallel Sequence Spread Spectrum (PSSS) as its spreading transform. This technique call...
