Limonium strictissimum Arrigoni
No full textLimonium strictissimum (Salzm.) Arrigoni − Côte de l’Ile Cavallo, très nombreux pieds, certains très grands, sur le sable des criques exposées au sud et au nord-est ainsi que sur les rochers proches de ces criques, 15.3.201 4, Delage A., F. Médail, G. Paradis, C. Piazza C. & J. Rosselo s.n. (Hb. privé Paradis). Ces localisations sont à ajouter aux stations déjà connues de ce statice endémique cyrno-sarde protégé (ARRIGONI & DIANA, Candollea 48: 631-677, 1993; PARADIS & PIAZZA, J. Bot. Soc. Bot. Fr. 23: 31-41, 2003; PARADIS, Bull. Soc. Bot. Centre-Ouest, n.s. 36: 151-158, 2005; TISON, Candollea 67: 316, 2012). Cette espèce mérite dès lors davantage le statut de fréquence R (rare) plutôt que RR (très rare).Published as part of Jeanmonod, Daniel, 2015, Notes à la flore de Corse, XXV, pp. 109-140 in Candollea 70 (1) on page 135, DOI: 10.15553/c2015v701a10, http://zenodo.org/record/572089

(Hb. privé); Ile Cavallo, sur la côte sud, 300 m au NW du port, en exposition SW sur un affleurement de dolérite, plusieurs petits individus avec Crithmum maritimum, Sporobolus pungens, Reichardia picroides, Lotus cytisoides subsp. cytisoides, 14.3.201 4, Delage A., F. Médail, G. Paradis, C. Piazza & J. Rosselo s.n. (Hb. privé Paradis). Ces deux stations étendent nettement l’aire de répartition de cette endémique corse qui, jusqu’à maintenant, n’était connue que des affleurements doléritiques compris entre la Cala di U Merlu et la Tonnara (ARRIGONI & DIANA, Candollea 48: 631-677, 1993; PARADIS & CULIOLI, Bull. Soc. Bot. Centre-Ouest 33: 9-20, 2003). Sur la Punta Capineru, deux autre espèces de Limonium (L. contortirameum et L. strictissimum) sont très abondantes.Published as part of Jeanmonod, Daniel, 2015, Notes à la flore de Corse, XXV, pp. 109-140 in Candollea 70 (1) on page 135, DOI: 10.15553/c2015v701a10, http://zenodo.org/record/572089
Decentralized fast-MPC path planner for automated vehicles
No full textSafe path-planning in an environment subject to the presence of other vehicles or obstacles in general is a crucial task for autonomous vehicle development. A complete control scheme is designed in order to test a decentralized fast MPC path planner algorithm. The proposed control scheme is composed by a receding replanner based on a fast numerical implementation of a nonlinear optimization problem and PIDs as trajectory tracker. A detailed description of the control problem formulation is provided as well as the mathematical models of vehicle considered. Numerical simulations of the control are discussed and finally conclusions are drawn
MPC trajectory planner for autonomous driving solved by genetic algorithm technique
No full textFocusing on autonomous driving algorithm development, this paper proposes a novel real-time trajectory planner formulated as a Nonlinear Model Predictive Control (NMPC) algorithm. The mathematical formulation of the problem is deeply reported and discussed. The numerical solution of the NMPC problem is the result of a novel genetic algorithm strategy that represents the innovative aspect of the work proposed. The aim of this paper is also to show how genetic algorithm can be a valid approach for motion planning strategies. Numerical results are discussed through simulations that show a reasonable behaviour of the proposed strategy in the presence of moving obstacles as well as in a wide range of road friction conditions. Moreover, a real-time implementation for research purposes is assumed as possible by considering computational time analysis reported

Assessing the orbital selective Mott transition with variational wave functions
No full textWe study the Mott metal-insulator transition in the two-band Hubbard model with different hopping amplitudes t_1 and t_2 for the two orbitals on the two-dimensional square lattice by using non-magnetic variational wave functions, similarly to what has been considered in the limit of infinite dimensions by dynamical mean-field theory. We work out the phase diagram at half filling (i.e. two electrons per site) as a function of R = t_2/t_1 and the on-site Coulomb repulsion U, for two values of the Hund's coupling J = 0 and J/U = 0.1. Our results are in good agreement with previous dynamical mean-field theory calculations, demonstrating that the non-magnetic phase diagram is only slightly modified from infinite to two spatial dimensions. Three phases are present: a metallic one, for small values of U, where both orbitals are itinerant; a Mott insulator, for large values of U, where both orbitals are localized because of the Coulomb repulsion; and the so-called orbital-selective Mott insulator (OSMI), for small values of R and intermediate U's, where one orbital is localized while the other one is still itinerant. The effect of the Hund's coupling is two-fold: on one side, it favors the full Mott phase over the OSMI; on the other side, it stabilizes the OSMI at larger values of R
