A Flexible Chain Proposal for Winch-Based Point Absorbers

Journal of Mechanical Design, 2018
Ocean wave power is a promising renewable energy source. It has, however, been difficult to find a cost-effective solution to convert wave energy into electricity. The harsh marine environment and the fact that wave power is delivered with large forces at low speed make design of durable mechanical structures and efficient energy conversion challenging.

80-Gb/s OTDM system analysis of a vertical microcavity-based saturable absorber for the enhancement of pulse pedestal suppression [PDF]

, 2007
In future high-speed optical time-division-multiplexed (OTDM) systems, an important factor that needs to be considered for optical pulse generation schemes is the impact of pulse pedestals on the overall system performance.

Brock's approaching zero method improved as approaching fixed point frequency to solve optimum damping ratio of dynamic vibration absorber in machine tools and experimental confirmation.

PLoS ONE
The design parameters of the dynamic vibration absorber significantly affect the motion performance of the main vibration system. The Brock's approaching zero method was improved as approaching the fixed point frequency method.
