(Il)légitimité du renseignement financier : usages transnationaux de la traçabilité des flux de capitaux

Criminologie, 2014
Cet article est consacré à un enjeu encore trop peu étudié malgré son importance croissante dans un domaine tel que le policing transnational, à savoir le renseignement financier.

K‐CC‐MoCo: A Fast k‐Space‐Based Respiratory Motion Correction for Highly Accelerated First‐Pass Perfusion Cardiovascular MR

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose First‐pass perfusion cardiovascular MR (FPP‐CMR) enables the non‐invasive diagnosis of microcirculation and coronary artery disease. In free‐breathing FPP‐CMR, motion correction is usually performed in the image domain, requiring an initial reconstruction.

La criminalité environnementale transnationale : aux grands maux, les grands remèdes ?

Criminologie, 2014
Cette étude propose la façon dont la communauté internationale devrait traiter la criminalité environnementale transnationale. Pour y arriver, l’auteur définit d’abord ce phénomène et discute de son ampleur.

On the Convergence of Conjugate Gradient and GMRES Algorithms in the Forward Backward Sweep Method for Optimal Control

Optimal Control Applications and Methods, EarlyView.
Optimal control combines state and adjoint equations, which yield the state (x$$ x $$) and adjoint (lambda) variables as a function of the control variables (u$$ u $$). This structure allows us to design strategies for iteratively updating the control variable, based on conjugate gradient (CG) or GMRES algorithms.

Applying Dynamics/Cost Parameter Continuation to the Optimal Guidance of Variable‐Speed Unicycle

Optimal Control Applications and Methods, EarlyView.
(a) Classical parameter continuation method diverges. (b) Dynamics/cost parameter continuation method converges. ABSTRACT The problem of a variable‐speed unicycle guidance to the stationary target is considered. The vehicle should be guided to the origin while minimizing the energy loss due to the induced drag.

Data assimilation with extremum Monte Carlo methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents the extremum Monte Carlo filter as a data assimilation method and, in particular, a variant of the variational approach (three‐ and four‐dimensional variational), where the state estimates are obtained by solving an optimization problem numerically over a space of prediction functions, instead of the state space itself.

Les personnes suicidaires peuvent-elles parler ? Théoriser l’oppression suicidiste à partir d’un modèle sociosubjectif du handicap

Criminologie, 2018
Malgré des appels répétés dans les campagnes de prévention du suicide pour que les personnes suicidaires s’expriment, plusieurs ne se sentent pas en sécurité de le faire. Puisque briser le silence est capital pour prévenir les suicides, la peur de parler

Adjoint methods for computing sensitivities in local volatility surfaces [PDF]

, 2010
In this paper we present the adjoint method of computing sensitivities of option prices with respect to nodes in the local volatility surface. We first introduce the concept of algorithmic differentiation and how it relates to\ud path-wise sensitivity ...
