After applying the bridging model to crack propagation data the scatter in the data was significantly reduced and clear trends were observed as a function of temperature that were not apparent previously.
A comparison with separate static fatigue experiments using unimpregnated fibre bundles demonstrated that the specific physico-chemical environment encountered by the glass fibres within the aged epoxy matrix can induce significant changes in the subcritical crack propagation rates, as compared to stress corrosion cracking data collected in humid air.
While a statement from the Director of National Intelligence, James Clapper — published after the reports by the Times and the Guardian — said that the fact that the N.S.A. works to crack encrypted data was "not news," Holt said, correctly, that "if in the process they degrade the security of the encryption we all use, it's a net national disservice".
The more forward-thinking groups might be more willing than most, but once the company works its way through the low-hanging fruit, this is a tough market to crack without data that wows.
Among the various pavement distresses, pavement cracking data is the most important element for quantifying the condition of pavement surface [2, 3], so it is crucial to detect and recognize the pavement cracking automatically and accurately before repairing them.
Although a reasonable correlation was found between IDT Nflex Factor with the FHWA ALF fatigue cracking data, the determination of Nflex Factor has several limitations.
A population balance model has been developed for catalyst properties, which is in good agreement with commercial fluid cracking data.
Model kinetic parameters are estimated via regression of cracking data obtained at temperatures relevant for industrial practice, 693 753 K.
Pavement cracking data collected in 2016 was compared with characteristics of asphalt cement supplied for paving and recovered from pavement cores at year five.
Unbeknown to the many users of the system, a different government arm, the National Security Agency, secretly inserted a "back door" into the system that allowed federal spies to crack open any data that was encoded using its technology.
