Reliability properties under a stopping time shift
(ELSEVIER SCIENCE BV, 2007)
Considering a series representation of a coherent system using a shift transform of the components lifetime T-i, at its critical level Y-i, we study two problems. First, under such a shift transform, we analyse the ...
Otimização da operação do alto-forno 1 da V&M do Brasil com "STAVE COOLER" através da distribuição de carga no topo do forno.

V&M Brazil Blast Furnace 1 is the first charcoal operating furnace in the world with copper "stave cooler". As a new technology, for this type of reactor, the furnace operation was started taking in account some basis ...
Combined Cycle Unit Controllers Modification for Improved Primary Frequency Regulation
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
During the past few decades the combined cycle unit dynamics and its associated controllers have become an important research subject. It has now become necessary to understand the operation and existing control strategies ...
CMOS-based active pixel for low-light-level detection: Analysis and measurements
(2007-12-01)
An analysis of the active pixel sensor (APS), considering the doping profiles of the photodiode in an APS fabricated in a 0.18 μm standard CMOS technology, is presented. A simple and accurate model for the junction capacitance ...
