The equivalent nonlinearity for a nonlinear system with dither
Journal of Mathematical Analysis and Applications, 1973 AbstractGiven a single loop nonlinear control system. The problem of constructing a dither signal in order to obtain a desired equivalent nonlinearity is considered. It is assumed that the nonlinearity may be described by a kth order polynomial. For this case it is shown that in general k different levels for the dither signal are necessary.

Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase
FEBS Open Bio, EarlyView.The activity of lytic polysaccharide monooxygenase (LPMO) is supported by its auxiliary enzyme cellobiose dehydrogenase (CDH). The catalytic activity of both enzymes is coupled by electron transfer and a cyclic cascade generating substrates for both enzymes – hydrogen peroxide for LPMO and oxidized and non‐oxidized cellobiose and cello‐oligosaccharide ...

Estimator-Based Control for Pure-Feedback Systems With Incomplete Measurements
IEEE Access, 2020 This paper investigates estimator-based control problems for pure-feedback nonlinear systems with incomplete measurements due to the transmission packet losing or sensor saturation. The incomplete measurements can cause the state variables unavailable or

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities
Journal of Applied Clinical Medical Physics, EarlyView.Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net
