We applied the receiver function (RF) technique on high-quality teleseismic earthquake data recorded by RiftVolc broadband network from February 2016 to October 2017. calculate RFs at 17 stations, which are inverted estimate Vs, and Vp/Vs structure beneath Central Main Ethiopian Rift Eastern plateau. The observed slow S-wave velocity (Vs) in uppermost crust (<6 km depth) is interpreted a...

A digital dual-rate burst-mode receiver, intended to support 10 and 1 Gb/s coexistence in optical access networks, is proposed and experimentally characterized. The receiver employs a standard DC-coupled photoreceiver followed by a 20 GS/s digitizer and the detection of the packet presence and line-rate is implemented in the digital domain. A polyphase, 2 samples-per-bit digital signal processi...

This paper investigates and compares several highly efficient thermodynamic cycles that are suitable for coupling with particle-in-tube fluidized-bed solar receiver technology. In such a receiver, high-temperature particles used as both heat transfer fluid storage medium. A dense particle suspension (DPS) is created through an upward bubbling (UBFB) flow inside the tubes, which constitutes “par...

An optical receiver using a CMOS-compatible avalanche photodetector (CMOS-APD) is demonstrated. The CMOS-APD is fabricated with 0.18 μm standard CMOS technology and the optical receiver is implemented by using the CMOS-APD and a transimpedance amplifier on a board. The optical receiver can detect 6.25-Gb/s data with the help of the series inductive peaking effect.

A novel RF-optical receiver architecture based on nonlinear optical modulation in a LiNbO3 microdisk modulator is presented. This is the first RF-optical receiver without high-speed electronic components for transmitted carrier links. We demonstrate receiver operation by demodulating 50 Mb/s digital data from a 8.7 GHz carrier frequency. 2005 Elsevier Ltd. All rights reserved.
