This paper discusses the convenience of predicting, quantitatively, time-dependent reliability and availability levels associated with most building or civil engineering structures. Then, the paper reviews different approaches to these problems and proposes the use of discrete-event simulation as the most realistic way to deal with them, specially during the design stage. The paper also reviews previous...
The growing presence of discharge lamps in power distribution systems has increased the harmonic distortion in these systems. The paper studies the magnetic ballast discharge lamp modelization with and without harmonic interaction. The supply harmonic voltage influence on lamp behavior is analyzed by Monte Carlo simulation. The results are validated with experimental measurements.
The Tile Calorimeter, which constitutes the central section of the ATLAS hadronic calorimeter, is a non-compensating sampling device made of iron and scintillating tiles. The construction phase of the calorimeter is nearly complete, and most of the effort now is directed toward the final assembly and commissioning in the underground experimental hall. The layout of the calorimeter and the tasks carried...
