Fault detection and accommodation strategy for a nonlinear system is proposed in this paper. The faults only related to the system states are considered, these typical faults are very common in physical systems. The basis idea is that when the desired trajectory is periodic, then the fault function can be expended to parameterized known basis functions by Fourier series, and thus an adaptive learning...
DPPH assay and FRAP assay (Ferric Reducing Antioxidant Power) were used to determine the antioxidant activity of forty kinds of Chinese herbs. Among them, eight were found to possess strong antioxidant activity including Magnolia and Rhus chinensis Mill.. Eight Chinese herbs were used to perry brewing. Total polyphenols were determined by Folin-Ciocaileu method in order to measure their antioxidant...
For the purpose of obtaining probiotic starters to produce functional pickles, 59 strains were isolated from 15 samples of brine And two promising strains labled A18 and B17 were screened out according to their ability of producing organic acid and survival in the models environment of stomach and small intestine. The strians were identified and analyzed by morphology properties of the colony and...
Long-term fatigue analysis of welded multi-planar tubular joints for a fixed jacket offshore wind turbine designed for a North Sea site in a water depth of 70 m is performed. The dynamic response of the jacket support structure due to wind and wave loads is calculated by using a decoupled procedure with good accuracy (Gao et al., 2010). Hot-spot stresses at failure-critical locations of each reference...
Abstract-The anti-fatigue effect of Eucommia ulmoids leaves in mice was studied in this research. Different extracts were prepared: water extract (EUH) and 80% ethanol extract (EUE) of Eucommia ulmoids leaves. The weight-loaded swimming time and biochemical parameters, such as blood lactic acid (LA), serum urea nitrogen (SUN), hepatic glycogen and muscle glycogen were investigated. The results showed...
In order to enhance cell and spore concertration of Bacillus Licheniformis SH003, the optimum fermentation conditions of Bacillus Licheniformis SH003 were studied by single-factor test in shake flasks conditions. The results indicated that culture conditions were: agar volume 40mL, inoculum concentration 10%, initial pH 6.5, growth temperature 35°C, fermentation time 36h and shaker rotating speed...
