The electromagnetic radiation that followed the neutron star merger event GW170817 revealed gamma-ray burst afterglows from jets misaligned with our line of sight exhibit a light curve slowly rising flux. slope depends sensitively on angle observer respect to jet axis, which is likely be perpendicular plane binary. Therefore, afterglow emission can used constrain inclination merging system. Her...

To investigate the seismic response characteristics of piled wharf structures, a numerical model soil-structure interaction system is established. Extensive fiducial error and grey correlation analyses are also conducted to obtain degree sequence internal force structure deformation, as well acceleration surrounding soils. The results show that peak at typical point soil more sensitive variatio...

We consider a wave equation with nonlocal logarithmic damping depending on small parameter 0 < ? 1 2 . This research is counter part of that was initiated by Charão-D'Abbicco-Ikehata considered in [5] for the large case > study Cauchy problem this model R n to ? ( , ) and we obtain an asymptotic profile optimal estimates time solutions as t ? ? L -sense. An important discovery when = can presen...
