Significant demonstration of machining procedures, applied successfully in industries such as aeronautics or automotive to mitigate against SCC, is included in the test programme. ATLAS+4 (Advanced Structural Integrity Assessment Tools for Safe Long Term Operation) began in June 2017 and runs for 4 ...

Objective To examine changes in daily rates of preterm and early-term birth after heat waves in a 25-year nationwide study. Design, Setting, and Participants This cohort study of singleton births used birth records from 1993 to 2017 from the 50 most populous US metropolitan statistical areas (...
Macroscopic Fundamental Diagram (MFD) is widely used in traffic state evaluation due to its description of the macro level of urban road network. This study focuses on the discrimination and short-term prediction of macro traffic states in urban road networks, using MFD combined with FCM clustering...
Fast probability integration method is used to perform probabilistic simulation of uncertainties. Sensitivity of fatigue life reliability to uncertainties in the primitive random variables are computed and their significance in the reliability based design for maximum life is discussed. The results show ...
Addressing Financial Objections to Sustainable Design and Construction In addition to talking about important features of green building, such as decreased use of energy, water, and other natural resources, we need to emphasize the benefits of green building in terms that resonate with key decision ...
(three females) were isolated for 120 days. Accompanying exercise training consisted of a continuous and interval running protocol in a cross-over design. Incremental stage tests on a treadmill were done frequently to test physical performance. Actigraphy was used to monitor physical activity level. ...
