Data-Driven (DD) computing is an emerging field of Computational Mechanics, motivated by recent technological advances in experimental measurements, the development highly predictive computational models, data storage and processing, which enable transition from a material data-scarce to data-rich era. The capability DD simulations contingent on quality set, i.e. its ability closely sample all ...

This paper reports on the development of an acoustic sea ice thickness measurement sensor. The development is applying acoustic NonDestructive-Testing (NDT) techniques to test first year sea ice including significant amounts of enclosed air bubbles. Two single piezoelectric transducers are tightly placed on smoothed sea ice surface to emit and receive acoustic signals. Besides seeing a detectab...

BACKGROUND Francophones who live outside the primarily French-speaking province of Quebec, Canada, risk being excluded from research by lack of a sampling frame. We examined the adequacy of random sampling, advertising, and respondent-driven sampling for recruitment of francophones for survey research. METHODS We recruited francophones residing in the city of Calgary, Alberta, through adverti...
