Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Speckle Observations With PISCO in Calern (France): III. Astrometric Measurements of Visual Double Stars in 2019 and New or Revised Orbits for STT531 AB, STT77 AB, STF1338 AB, COU1746, STT260, A1109 AB, HU1291, and A632 AB

Astronomische Nachrichten, EarlyView.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2019 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.

Pharmacokinetic Assessment of Atazanavir and Favipiravir Following Echinacea Supplementation: A Controlled Herb–Drug Interaction Investigation

Biopharmaceutics &Drug Disposition, EarlyView.
Pharmacokinetic interactions between Echinacea and two antiviral drugs, favipiravir and atazanavir, were assessed in rats. The findings suggest that Echinacea does not significantly affect the pharmacokinetics of favipiravir and atazanavir. These results provide preliminary evidence that concurrent use of Echinacea with these antiviral drugs may be ...

Breaking point: Identifying the factors that predict suspension from school

British Educational Research Journal, EarlyView.
Abstract School suspensions are associated with adverse educational and psychosocial outcomes, yet little is known about how structural disadvantage, relational factors, health behaviours, well‐being indicators and school‐level factors jointly predict suspension risk in England.

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling

Biotechnology and Bioengineering, EarlyView.
Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and
