Origin, petrogenesis and geodynamic implications of the early Eocene Altinpinar adakitic andesites in the eastern Sakarya Zone, northeastern Turkey
(Elsevier Gmbh, 2021)
Early Cenozoic magmatism in the eastern Sakarya Zone (NE Turkey) provides an important constraint on the regional tectono-magmatic evolution of the region. Early Eocene syn-collisional adakitic rocks are observed as small ...
Analysis of Mining Lost Time Incident Duration Influencing Factors Through Machine Learning
(Springer Heidelberg, 2021)
Despite technological advancements and organizational adjustments, lost time accidents are major issues in occupational safety. However, there is very limited work that focuses on variables influencing days lost as a result ...
A reduced variance unsupervised ensemble learning algorithm based on modern portfolio theory
(Pergamon-Elsevier Science Ltd, 2021)
Unsupervised ensemble learning or consensus clustering has gained popularity due to its ability to combine multiple clustering solutions into a single solution that is robust and often performs better than the individual ...
