Cet essai propose un portrait moral et philosophique de Jean-Paul Brodeur. Retraçant divers moments de sa formation en philosophie et rappelant ses premiers intérêts, je propose une esquisse de l’évolution de Jean-Paul Brodeur, à partir d’une critique de la philosophie spéculative menée au nom de l’objectivité des sciences sociales jusqu’à l’adoption d’

Index of a bivariate mean and applications
Exploring some results of (Raïssouli in J. Math. Inequal. 10(1):83-99, 2016) from another point of view, we introduce here some power-operations for (bivariate) means.

Mean ergodicity vs weak almost periodicity
We provide explicit examples of positive and power-bounded operators on $c_0$ and $\ell^\infty$ which are mean ergodic but not weakly almost periodic. As a consequence we prove that a countably order complete Banach lattice on which every positive and ...

Fluctuations of company yearly profits versus scaled revenue: Fat tail distribution of Levy type
We analyze annual revenues and earnings data for the 500 largest-revenue U.S. companies during the period 1954-2007. We find that mean year profits are proportional to mean year revenues, exception made for few anomalous years, from which we postulate a ...

Power mean based image segmentation in the presence of noise
In image segmentation and in general in image processing, noise and outliers distort contained information posing in this way a great challenge for accurate image segmentation results.

Fluctuation and Dissipation in Liquid Crystal Electroconvection
In this experiment a steady state current is maintained through a liquid crystal thin film. When the applied voltage is increased through a threshold, a phase transition is observed into a convective state characterized by the chaotic motion of rolls ...

A Best Possible Double Inequality for Power Mean
We answer the question: for any p,q∈ℝ with p≠q and p≠-q, what are the greatest value λ=λ(p,q) and the least value μ=μ(p,q), such that the double inequality Mλ(a,b)

The origin of power-law distributions in self-organized criticality
The origin of power-law distributions in self-organized criticality is investigated by treating the variation of the number of active sites in the system as a stochastic process.

A necessary and sufficient condition for the inequality of generalized weighted means
We present in this paper a necessary and sufficient condition to establish the inequality between generalized weighted means which share the same sequence of numbers but differ in the weights.

On Wireless Scheduling Using the Mean Power Assignment
In this paper the problem of scheduling with power control in wireless networks is studied: given a set of communication requests, one needs to assign the powers of the network nodes, and schedule the transmissions so that they can be done in a minimum ...
