The Anelasticity of the Mantle*

Don L. Anderson
2010 Geophysical Journal of the Royal Astronomical Society  
If attenuation in the mantle is due to an activated process it is probably controlled by the diffusion rate of defects at grain boundaries.  ...  A frequency dependence of Q has not yet been discovered.  ...  California Institute of Technology, Seismological Laboratory, Pasadena, California.  ...

Intra-domain and cross-domain transfer learning for time series data – How transferable are the features?

Erik Otović, Marko Njirjak, Dario Jozinović, Goran Mauša, Alberto Michelini, Ivan S̆tajduhar
2021 Knowledge-Based Systems  
Transfer of knowledge was performed within the same domain of application (seismology), as well as between mutually different domains of application (seismology, speech, medicine, finance).  ...  In practice, it is very demanding and sometimes impossible to collect datasets of tagged data large enough to successfully train a machine learning model, and one possible solution to this problem is transfer  ...  Each participant performed three sessions in which each gesture was performed five times for two seconds. Between the two movements is a period of relaxation lasting one second.  ...
