Optimisation d’un moteur Stirling de type gamma
Revue des Énergies Renouvelables, 2010 La nécessité de réduire les émissions de dioxyde de carbone (CO2) a conduit à revaloriser les moteurs à combustion externe fonctionnant selon le cycle de Stirling.

Stirling Permutations, Cycle Structure of Permutations and Perfect Matchings [PDF]
The Electronic Journal of Combinatorics, 2015 In this paper we provide constructive proofs that the following three statistics are equidistributed: the number of ascent plateaus of Stirling permutations of order $n$, a weighted variant of the number of excedances in permutations of length $n$ and the number of blocks with even maximal elements in perfect matchings of the set $\{1,2,3,\ldots,2n\}$.

From Pirates to Professionals: Retaining a Sense of Integration During Venture Scaling
British Journal of Management, EarlyView.Abstract Our paper explains how organizations can build and sustain internal member identification during rapidly scaling transitions. Using a longitudinal case study of a UK scaling firm, we show how organizational members follow a recursive process of retaining and forgoing the past and foreseeing the future to create a transitional organizational ...

Journal of Religious History, EarlyView.Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

Optimizing thermodynamic trajectories using evolutionary and gradient-based reinforcement learning [PDF]
, 2019 Using a model heat engine, we show that neural network-based reinforcement learning can identify thermodynamic trajectories of maximal efficiency. We consider both gradient and gradient-free reinforcement learning.
