LMI based design for the Acrobot walking [PDF]

IFAC Proceedings Volumes, 2009
Abstract This paper aims to further improve previously developed design for Acrobot walking based on partial exact feedback linearization of order 3. Namely, such an exact system transformation leads to an almost linear system where error dynamics along trajectory to be tracked is a 4-dimensional linear time-varying system having 3 time-varying ...

Enhancing Polydimethylsiloxane with Silver Nanoparticles for Biomedical Coatings

Biomimetics
Silver nanoparticles (AgNPs) are widely used as antibacterial agents either as colloidal solutions or deposited on surfaces. However, the high concentration of AgNPs can lead to cytotoxicity, posing a hazard to healthy cells and tissues.

Impact of organic fertilisation on lettuce biomass production according to the cultivation duration in tropical soils

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2020
The productivity levels of two arenosol (Ar40) and fluvisol (FL40) fields that had been cultivated for over 40 years were compared to that of fields with the same soils located nearby but never previously cultivated, i.e.

Preliminary Observations from the China Fengyun-4A Lightning Mapping Imager and Its Optical Radiation Characteristics

Remote Sensing, 2020
The Fengyun-4A (FY-4A) Lightning Mapping Imager (LMI) is the first satellite-borne lightning imager developed in China, which can detect lightning over China and its neighboring regions based on a geostationary satellite platform.

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 ...

Clinical Significance of Acute Kidney Injury in Idiosyncratic Drug‐Induced Liver Injury: A Multicentric Propensity Scores Matched Study

Clinical Pharmacology &Therapeutics, EarlyView.
Clinical significance of acute kidney injury in idiosyncratic drug‐induced liver injury: a multicentric propensity scores matched study. Evidence about the role of acute kidney injury (AKI) in idiosyncratic drug‐induced liver injury (DILI) is still scarce.
