Determination of Asphalt Binder VECD Parameters Using an Accelerated Testing Procedure

Fatigue characteristics of asphalt binder have an important role in asphalt mix resistance against cracking. Viscoelastic Continuum Damage (VECD) analysis of asphalt binders has been successfully used in highway research works in order to predict fatigue behavior of hot mix asphalt (HMA). In this method an intrinsic property of the material, called damage function is obtained which is independe...

Permeability of Natural Clay Liners: Effect of Accelerated Permeability Testing on Soil Structure

A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted. The specimens were then freeze-dried to preserve their post-test ...

CONSTANT STRESS ACCELERATED LIFE TESTING DESIGNWITH TYPE-II CENSORING SCHEME FOR PARETO DISTRIBUTION USING GEOMETRIC PROCESS

In many of the studies concerning Accelerated life testing (ALT), the log linear function between life and stress which is just a simple re-parameterization of the original parameter of the life distribution is used to obtain the estimates of original parameters but from the statistical point of view, it is preferable to work with the original parameters instead of developing inferences for the...

Design of Accelerated Life Testing Plans for Products Exposed to Random Usage

< p>Accelerated Life Testing (ALT) is very important in evaluating the reliability of highly reliable products. According to ALT procedure, products undergo higher stress levels than normal conditions to reduce the failure times. ALTs have been studied for various conditions and stresses. In addition to common stress such as temperature and humidity, random usage can also be considered as anoth...

Testing a normalbation procedure for articulator recovery

i A normalization procedure was tested in which the vocal tract length and the functions determining the conversion of midsagittal distance to cross-sectional area in an articulstory synthesizer were adjusted until there was an acoustic match between the articulator synthesizer and a human over a selected set of vowels. Another part of the normalization procedure was to train neural networks to...
