  • Fractal dimension and phase transition of graphene oxide (GO) doped polyacrylamide 

    Authors:Evingür, Gülşen Akın; Pekcan, Önder
    Publisher and Date:(ELSEVIER SCI LTD, 2020)
    Graphene Oxide (GO)- Polyacrylamide composites prepared between 5 and 50 mu l GO were performed by Fluorescence Spectroscopy. The phase transition performed on the composites was measured by calculating the critical exponents, beta and gamma, respectively. In addition, fractal analysis of the composites was calculated by a fluorescence intensity of 427 nm. The geometrical distribution of GO in the composites was calculated based on the power law exponent values using scaling models. While the ...

  • Machine learning algorithms for lamb survival 

    Authors:Emsen, Ebru; Aydın, Man Nuri; Ödevci, Bahadır
    Publisher and Date:(ELSEVIER SCI LTD, 2021-03)
    Lamb survival is influenced by the culmination of a sequence of often interrelated events including genetics, physiology, behaviour and nutrition, with the environment providing an overarching complication. Machine learning algorithms offer great flexibility with regard to problems of complex interactions among variables. The objective of this study was to use machine learning algorithms to identify factors affecting the lamb survival in high altitudes and cold climates. Lambing records were ...
