Prototype testing of the wave energy converter wave dragon [PDF]
Renewable Energy, 2006 The Wave Dragon is an offshore wave energy converter of the overtopping type. It consists of two wave reflectors focusing the incoming waves towards a ramp, a reservoir for collecting the overtopping water and a number of hydro turbines for converting the pressure head into power.

Testing BSM physics with gravitational waves
Journal of Cosmology and Astroparticle Physics, 2023 Abstract The Cosmic Gravitational Wave Background (CGWB) is an irreducible background of gravitational waves generated by particle exchange in the early Universe plasma. Standard Model particles contribute to such a stochastic background with a peak at f∼80 GHz.

Plane Wave Reverse Time Image for Nondestructive Tests
IEEE Access, 2023 Reverse time migration (RTM) has been a popular method in industry duo to its ability of imaging complex subsurface and no dip restriction. However, RTM based on full matric capture (FMC) data is limited by the time cost of the calculation and cannot be ...

The Test Ability of an Adaptive Pulse Wave for ADC Testing [PDF]
2010 19th IEEE Asian Test Symposium, 2010 In the conventional ADC production test method, a high-quality analogue sine wave is applied to the Analogue-to-Digital Converter (ADC), which is expensive to generate. Nowadays, an increasing number of ADCs are integrated into a system-on-chip (SoC) platform design, which usually contains a digital embedded processor.
