## Abstract It is commonly understood that earthquake ground excitations at multiple supports of large dimensional structures are not the same. These ground motion spatial variations may significantly influence the structural responses. Similarly, the interaction between the foundation and the surr

The inlcraction of triplet excitons and protons in molecular crystals gives rise to n longitudinal relsxation time TI ex of the protens. We calculate the dependence of Tt ex on the external magnetic field, on the dimensionality and on the kind of the exciton motion. Beyond this the optical nuclear s
## Abstract Coherency functions are used to describe the spatial variation of seismic ground motions at multiple supports of long span structures. Many coherency function models have been proposed based on theoretical derivation or measured spatial ground motion time histories at dense seismographi
