摘要:In this study we investigate directivity effects associated to the Mw6.0 Amatrice earthquake taking into account the source rupture heterogeneities. We use the directivity predictor proposed by Spudich et al. (2004) which is derived from the isochrones theory. The directivity is ...

摘要:... The objective of this paper is to assess directivity effects on ground motions recorded during the 2011 Lorca earthquake, and to evaluate the significance of these effects in earthquake resistant design on moderate seismic regions. In the first part of this paper, we study th...

摘要:Abstract(#br)How to incorporate near-fault directivity effect into the ground motion prediction equations (GMPEs) is an active research topic in recent years. Many studies demonstrated that the directivity could amplify the spectral accelerations ( S a ) in a range close to the p...

摘要:This paper studies the benefits that power control and antenna directivity can bring to the capacity of a multiuser cognitive radio network. The main objective is to optimize the secondary network sum rate under the capacity constraint of the primary network. Exploiting location ...

摘要:... The noise radiated by vibrating plates is mainly determined by three factors: the mean-square vibration, the radiation efficiency of the plates and the directivity of the sound. Although the first two factors have been widely investigated, much less attention has been paid to...

摘要:Abstract(#br)This paper presents a method to calculate the full 3D directivity balloon of dodecahedron sound sources based on simple laboratory measurements and spatial rotations. Dodecahedron-shaped loudspeakers are used extensively in acoustic measurements. Knowledge of the 3D ...

摘要:Abstract(#br)We investigate the role of major seismological (magnitude, pulse period, fault length, seismic activity, orientation of incident seismic wave with respect to fault-strike) and geometrical (fault-site geometry) parameters to understand the variations in ground-motion demands due to near-fault directivity...
