Chemical properties and decay resistance of eucalyptus grandis wood from steamed logs
(2012-12-01)
The objective of this study was evaluate the effect of the log steaming on the chemical properties and decay resistance of Eucalyptus grandis wood. Logs with diameter between 20 and 22 cm were studied. Half of logs were ...

Design of a state observer using decay rate LMI constraints for fault detection in mechanical systems
(2010-01-01)
Nowadays, one of the most important concerns for many companies is to maintain the operation of their systems without sudden equipment break down. Because of this, new techniques for fault detection and location in mechanical ...

Analytical models of soil and litter decomposition: Solutions for mass loss and time-dependent decay rates
(Elsevier, 2012-07)
Combining decomposition data with process-based biogeochemical models is essential to quantify the turnover of organic carbon (C) in surface litter and soil organic matter (SOM). Long-term decomposition may be suitably ...
Short-term temporal changes of soil carbon losses after tillage described by a first-order decay model
(Elsevier B.V., 2008-04-01)
Tillage stimulates soil carbon (C) losses by increasing aeration, changing temperature and moisture conditions, and thus favoring microbial decomposition. In addition, soil aggregate disruption by tillage exposes once ...

Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
(2011-05-01)
In some practical problems, for instance, in the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Thus, a method for state-derivative feedback design ...
