TL;DR: In this paper, the evolution of the information seeking and use models for professionals, essentially, the information access practices, is discussed. But two main categories can be distinguished : the informationseeking and use model versus the information retrieval model, and we will evaluate them in order to see if a convergence is possible with the same vocabulary and procedures.

TL;DR: The first phase of the Pierre Auger Observatory has been completed and all of the sub-systems that will be used in the full instrument to be tested under field conditions as discussed by the authors.

TL;DR: In this paper, a composition analysis of KASCADE air shower data is performed by means of unfolding the two-dimensional frequency spectrum of electron and muon numbers, and the analysis is the determination of energy spectra for elemental groups representing the chemical composition of primary cosmic rays.

TL;DR: The KASCADE experiment as mentioned in this paper was designed to measure air showers of primary cosmic-ray energies in the PeV region and to investigate the knee phenomenon in the all-particle energy spectrum.

TL;DR: In this paper, an efficient scheme for one-dimensional extensive air shower simulation and its implementation in the program conex is presented, where explicit Monte Carlo simulation of the high-energy part of hadronic and electro-magnetic cascades in the atmosphere is combined with a numeric solution of cascade equations for smaller energy sub-showers to obtain accurate shower predictions.
