Identification and control of aircraft dynamics using radial basis function networks
(Publ by IEEE, 1993)In this paper, we investigate one type of neural networks, namely the Radial Basis Functions (RBF) networks, and apply them to the identification and control problems of an aircraft system. The RBF network is used as an ...

Inclusive e+e pair production in p+p and p+Nb collisions at Ekin = 3.5 GeV
(2011)We report on recent data of e+e pair emission in proton nucleus collisions at energies above the light vector meson production thresholds. Invariant mass distributions for the p+Nb system at Ekin = 3.5 GeV are compared ...

Modeling sociopoliticoeconomic systems with timedependent fuzzy cognitive maps
(2012)Most of the formalisms of fuzzy cognitive maps (FCM) that had been proposed and applied in the past are relatively simple in the sense that they handle the various interacting and timevarying concepts as zerothorder ...

Molecular dynamic simulations of carbon nanotubes in CO2 atmosphere
(2008)This work investigates by means of molecular dynamics the filling of carbon nanotubes by carbon dioxide molecules. Nanotubes of various sizes are simulated and the resulting CO2 density calculated. The effects of various ...

Article
Molecular simulation of water in carbon nanotubes
(2008)The motion of water in carbon nanotubes (CNT) by numerical procedures is calculated through molecular dynamics (MD) simulation studies. The LennardJones potential is a simple MD simulations technique, which combines ...

N and N to Δ transition form factors from lattice QCD
(2007)We present recent lattice QCD results on nucleon form factors and N to Δ transition form factors. We predict the parity violating asymmetry in N to Δ and check the offdiagonal GoldbergerTreiman relation.
