We describe a new measurement of the intensities heavy primary cosmic-ray nuclei O, Ne, Mg, Si, and Fe from 10 GeV amu-1 to energies beyond 1 TeV amu-1. The was conducted in 1999 during day test flight Transition Radiation Array for Cosmic Energetic (TRACER), telescope designed long-duration balloon flights. TRACER uses an array thin-walled single-wire proportional tubes determine particle Lorentz factor measurements specific ionization transition radiation. nuclear charge is obtained with...

The instability of the aircraft's flexible control surfaces caused by uncontrolled vibrations represents a challenging issue aviation security. Flutter is violent vibration whose amplitude grows strongly in short time. Once flutter reached, plane destabilized and it can no longer be controlled. This paper proposes specially designed demonstrator intended to extend flight envelope raising speed limit at which occurs. anti-flutter an intelligent airplane wing model made from longeron covered...

We analyze on a classical 2D version of the "nuclear billiard" onset chaotic behaviour three-dimensional nucleonic trajectories in different dynamical states axially symmetric deformed nuclei. The coupling between single-particle and collective degrees freedom presence dissipation for several multipolarities is taken into account. examine order-to-chaos transition by studying Shannon entropies, which quantify time rate information production during certain motion. For monopole dipole...

Experimental data on the pion-nucleus total cross sections are analyzed in terms of optimal resonances predictions (OR). The OR-predictions found a good agreement with actual experimental region corresponding to Delta(1236) resonance elementary pi-N scattering. essential signatures experimentally verified high accuracy.

The WILLI detector, installed in the National Institute of Physics and Nuclear Engineering — Horia Hulubei Bucharest has been devised for studies atmospheric muons, particular muon charge ratio. We report on results various energies (pμ < 1 GeV/c). are compared with Monte‐Carlo simulations performed CORSIKA GEANT codes. exploring potential a small detector array to be set up nearby actual triggering ratio measurements by Extended Air Shower (EAS) events.
