DOI: 10.1002/nme.6350
Abstract: We present an interpolation scheme for use with material models involving history‐dependent state variables. The interpolation scheme is based on the solution of a constrained optimization problem, to identify the smoothest monotone curve which produces… read more here.

DOI: 10.1016/j.ifacol.2020.12.1920
Abstract: Abstract A key factor for the further distribution of biomass boilers in modern energy systems is the capability of changing the applied feedstock during normal plant operation. This is only possible with the application of… read more here.

DOI: 10.1111/ele.12788
Abstract: Simplified mechanistic models in ecology have been criticised for the fact that a good fit to data does not imply the mechanism is true: pattern does not equal process. In parallel, the maximum entropy principle… read more here.

DOI: 10.3390/sym12040513
Abstract: In several open and closed-loop systems, the trajectories converge to a region instead of an equilibrium point. Identifying the convergence region and proving the asymptotic convergence upon arbitrarily large initial values of the state variables… read more here.
