summarythe explanation of the elastic, or velocity structure of the earth has long been a goal of the world’s seismologists. for the first few decades of seismological research, the investigation on velocity structure was restricted to the determination of one-dimensional models of the solid earth and of various regions within it. seismologists are currently obtaining three dimensional velocity...
The nano-domain, with short-range ordered structure, has been widely observed in rare-earth-doped ceria. Atomistic simulation has been employed to investigate the ordering structure of the nano-domain, as a result of aggregation and segregation of dopant cations and the associated oxygen vacancies in gadolinium-doped ceria. It is found that the binding energy of defect cluster increases as a fu...
In this research the investigation concerning the earth structure beneath the Southwest North America landmass is carried out, which covers a small area, i.e. between Mexico and California. S speed models for this area are obtained by carrying out seismogram fitting in time domain and three simultaneous Cartesian components. Seismogram data are the effect of earthquake C052297B in Guererro, Mex...
