Asymmetric delayed relay feedback identification based on the n-shifting approach
(Taylor and Francis, 2021-08-20)
The paper presents an improvement of the n-shifting technique to identify the frequency response of an industrial process using a fully asymmetric and delaying relay. The n-shifting approach allows the calculation of n + 1 ...
Effect of the presence of lignin from woodflour on the compostability of PHA-based biocomposites: disintegration, biodegradation and microbial dynamics
(MDPI, 2023-05-27)
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) has gained attention as a possible substitute for conventional polymers that could be integrated into the organic recycling system. Biocomposites with 15% of pure cellulose ...
