Cet article est la synthèse et conclusion des journées "changements climatiques et forêt méditerranéenne" organisées en 2007 par l'association Forêt Méditerranéenne.
Transmission between small antenna coils at 10.8 MHz is investigated in free space and near a flat, conducting medium for different separations between the coils and heights above the medium. Models are derived, and a physical explanation is given. Excellent agreement is obtained between the measurements and the models.
The present study aims to design a multilayer microstrip antenna with composite sandwich construction and investigate fatigue behavior of this multilayer SAS ( surface antenna structure) that was asymmetric sandwich structure for the next generation of structural surface technology. This term, SAS, indicates that the structural surface becomes an a...
Does the food's sugar concentration affect recruitment behaviour in the stingless bee Nan-notrigona testaceicornis? We recorded intranidal forager behaviour while offering sugar water of constant, increasing, or decreasing concentrations. Running speed was not correlated with sugar concentration but the jostling contacts/sec were. Food profitabilit...
This paper studies communication mechanisms for two players with symmetric single-peaked preferences. The peaks are privately known and drawn from a uniform distribution before the agents take a collective decision. While for the general setting Moulin [Moulin, H., 1980. On Strategy-Proofness and Single-Peakedness. Public Choice 35, 437-455.] chara...

We derive the Cramer-Rao Lower Bound (CRLB) for the estimation of initial conditions of noise-embedded orbits produced by general one-dimensional maps. We relate this bound`s asymptotic behavior to the attractor`s Lyapunov number and show numerical examples. These results pave the way for more suitable choices for the chaotic signal generator in so...
