Fast estimation and tracking of the principal subspace of a sequence of random vectors is a classic problem, widely encountered in areas such as radar, sonar and speech processing, data compression, data filtering, parameter estimation, pattern recognition, neural analysis, wireless communications, to name just a few. Among the most robust algorithms for subspace tracking there are the so calle...

The experimental problem of the calibration of magnetic field in large iron detectors is discussed. Emphasis is laid on techniques based on ballistic measurements as the ones employed by MINOS or OPERA. In particular, we provide analytical formulas to model the behavior of the apparatus in the transient regime, keeping into account eddy current effects and the finite penetration velocity of the...

We deepen the study of the so-called “silver channel” νe → ντ [1] and of its relevance to solve some of the ambiguities that can arise in the simultaneous measurement of (θ13, δ) at the Neutrino Factory by presenting in full detail the characteristics of the considered OPERA-like detector and the experimental treatment of the different backgrounds and signals. Furthermore, we perform a detailed...

Sound exposures of Canadian Opera Company orchestra players were measured to assess the risk of hearing loss of players in orchestra pits. This was done during 18 sessions that included rehearsals, dress rehearsals and actual performances of two operas. Seventy-three noise exposures of musicians were measured using five dosimeters for the entire duration (3 h) of each event. The measured estima...

Visualization techniques can visually present and analyze data. This paper explores the visual field in culture of Sichuan opera. Firstly, it summarizes data opera analyzes characteristics Then, introduces five kinds visualization techniques: text visualization, hierarchical network spatio-temporal multidimensional their application cultural design Opera. Finally, puts forward prospect.

Violation of Lorentz invariance (VLI) has been suggested as an explanation of the superluminal velocities of muon neutrinos reported by OPERA. In this Letter, we show that the amount of VLI required to explain this result poses severe difficulties with the kinematics of the pion decay, extending its lifetime and reducing the momentum carried away by the neutrinos. We show that the OPERA experim...

We discuss two experiments ICANOE and OPERA that have been proposed within the context of long-baseline and atmospheric neutrino experiments in Europe. The joint ICANOE/OPERA program aims at further improving our understanding of the effect seen in atmospheric neutrinos. This program is based on (1) a continuation of the observation of atmospheric neutrinos with the improved technique of ICANOE...

In opera, the drama typically unfolds with transgressions against law or social norms. Legal conflict and crime are important devices used to hold audience interest. Opera embodies a rich combination of acting song, orchestral music, stage architecture, plethora other dramaturgical devices. The emotional connotations lawbreaking laid bare like in no form art. overwhelming effect on may well bal...

The increasing complexity of distributed applications requires new modeling and engineering approaches. Such domains require representing the regulating structures explicitly and independently from the acting components (or agents). Organization computational models, based on Organization Theory, have been advocated to specify such systems. In this paper, we present the organizational modeling ...
