The Makran Subduction Zone is the primary seismic/tsunami hazard of northwestern Indian Ocean, but little known its on-shore seismic structure. We derived a shear wave velocity model extending to 100 km depth beneath ∼400 km-long profile oriented parallel convergence vector Arabian Sea Plate. Receiver function/surface analysis shows that average structure in coastal region comprises ∼22–28 km-t...

[1] We estimate crustal structure and thickness of South America north of roughly 40°S. To this end, we analyzed receiver functions from 20 relatively new temporary broadband seismic stations deployed across eastern Brazil. In the analysis we include teleseismic and some regional events, particularly for stations that recorded few suitable earthquakes. We first estimate crustal thickness and av...

Design and implementation of a 2.5Gb/s CMOS transmitter and a 1.3Gb/s receiver for optical interconnections are presented. The transmitter accepts LVDS signals and converts it into optical signals. The receiver receives the optical signals and recovers it to LVDS signals. They are designed and implemented in standard 0.25um CMOS process using 1-poly and 5-metal layers. The 850nm VCSEL is assume...

SUMMARY In the field of seismic interferometry, cross-correlations are used to extract Green’s function from ambient noise data. By applying a single station variation method, using autocorrelations, we in principle able retrieve zero-offset reflections stratified Earth. These valuable as they do not require an active source and, being zero-offset, better constrained space than passive earthqua...
