Finally, the results are also likely to represent a conservative estimate of deterioration given that only the distal portion of the entire waiting period was assessed (for example, time spent waiting for an initial consultation with an orthopaedic surgeon was not included) and preadmission clinic dates were used to approximate the end of the waiting period.
Initially, Mr. Banducci said, his company was not worried because Toyobo's first estimate of the deterioration rate was 10percentt over a decade, while the vests were under warranty for five years.
Although the results indicate that the properties related to the degradative capacity of the soils varied differently in response to the contamination, the use of a biochemical quality index (including different biochemical properties), which was designed for estimating the degree of deterioration of the soil, revealed a clear decrease in the biochemical quality of the diesel-contaminated soils.
In this paper two commonly used predictive approaches are used to provide estimates of long-term deterioration for a range of material characteristics which are compared to experimental data obtained over a 3 years period of exposure.
Larry E. Murphy, an archaeologist for the National Park Service who went on the expedition, said it was done to determine how to measure multiple processes of decay and come up with a credible estimate of the rate of deterioration.
In this work an Extended Kalman Filter is explored to estimate the current state of deterioration assuming the knowledge of the operating conditions, input signals, and sensor information.
The study suggests that the ageing tests can provide information about the effects of environmental agents in the durability of bonded structures but cannot estimate the real amount of deterioration in real service life of such structures.
Structural health monitoring (SHM) provides a useful tool for ensuring integrity and safety, detecting the evolution of damage, and estimating performance deterioration of civil infrastructures.
With increasing number of F-T cycles, similar convergent decrease tendencies between the UCS, Ed, STS, C and the Vp, Ah, fc, KFS were found, confirming the effectiveness of the ultrasonic time-frequency method to estimate the deterioration of rock suffered from F-T weathering.
However, if sufficient historical data cannot be gathered to confidently estimate the deterioration of a new product, then the solution may not be assertively reliable.
