Span length and information rate optimisation in optical transmission systems using single-channel digital backpropagation.

Optics Express, 2017
The optimisation of span length when designing optical communication systems is important from both performance and cost perspectives. In this paper, the optimisation of inter-amplifier spacing and the potential increase of span length at fixed ...

Exact Dynamic Characteristic Analysis of Steel-Concrete Composite Continuous Beams

Shock and Vibration, 2021
The free vibration characteristics of steel-concrete composite continuous beams (SCCCBs) are analyzed based on the Euler–Bernoulli beam theory. A modified dynamic direct stiffness method has been developed, which can be used to analyze the SCCCBs with ...
