UNLABELLED Because of the limited number of projections, the mathematic reconstruction formula of the filtered backprojection (FBP) algorithm may create an artifact that streaks reconstructed images. This artifact can be imperfectly removed by replacing the ramp filter of the FBP with an ad hoc low-pass filter, the cost being the loss of contrast and(More)
The probability hypothesis density (PHD) methodology is widely used by the research community for the purposes of multiple object tracking. This problem consists in the recursive state estimation of several targets by using the information coming from an observation process. The purpose of this paper is to investigate the potential of the PHD filters for(More)

The study of hydraulic structures makes systematic use of mathematical models in order to verify their behaviour. On-line use of these models to synthesise predictive control permits basing control on almost perfect knowledge of every aspect of the process. Achieving this aim requires good management of the embedded numeric model and the incorporation of an(More)

In this thesis, I explore lattice independent duality and systems to which it can be applied. I first demonstrate classical duality on models in an external field, including the Ising, Potts, and x − y models, showing in particular how this modifies duality to be lattice independent and applicable to networks. I then present a novel application of duality(More)
