For practical evaluation, we conduct not only simulations but also experimental measurements by implementing a test program on a real test bed.
The performance of our method appears to be uncorrelated with the sleep efficiency and percentage of transitional epochs in each recording.. The optimal value of steam to biomass ratio in this work was 1 0 We developed a machine learning methodology for automatic sleep stage scoring.. 39% The introduction of steam improved gas quality, but a higher steam to biomass ratio could decrease carbon conversion and gasification efficiency owing to a low steam temperature.
52 MJ m −3 to 7 75 MJ m −3 and cold gas efficiency from 49 09% to 61.

The sensitivity analysis of operating parameters, such as the fluidisation velocity, oxygen percentage of the enriched air and steam to biomass ratios on the produced gas composition, lower heating value, carbon conversion and cold gas efficiency was investigated.. Our time-frequency analysis-based feature extraction is fine-tuned to capture sleep stage-specific signal features as described in the American Academy of Sleep Medicine manual that the human experts follow.. The higher fluidisation velocity enhanced gas–solid mixing, heat and mass transfers, and carbon fines elutriation, simultaneously.. A series of experiments were carried out under typical operating conditions for gasification, as reported in the article.. Our method has both high overall accuracy (78%, range 75–80%), and high mean F 1-score (84%, range 82–86%) and mean accuracy across individual sleep stages (86%, range 84–88%) over all subjects. 5ebbf469cd
