In this paper, state estimation for Switched Discrete-Time Linear Systems is performed using relaxed dynamic programming. Taking the Bayesian point of view, the estimation problem is transformed into an infinite dimension al optimization problem. The optimization problem is then solved using relaxed dynamic programming. The estimate of both the mode and the continuous state can then be computed fr
A passive system is one that cannot produce energy, a property that naturally poses constraints on the system. In this paper there is a review of some results on linear, time translational invariant, continuous, causal and passive systems, where it turns out that Herglotz functions are related to the Fourier transform of the impulse response of such systems. Some well known facts of this function
During oxidative phosphorylation, the production of ATP is driven by the activity of several proton-pumping respiratory protein complexes. In plants, non-proton pumping type II NAD(P)H dehydrogenases are also present in the respiratory chain to oxidize cytosolic and matrix NAD(P)H. So far, it has not been fully clear what roles these enzymes play in the cellular metabolism. In Arabidopsis thalian
This thesis investigates electronic transport in several types of novel heterostructure nanowires. The first part of the thesis focuses on band-to-band mechanisms in heterostructure nanowires for low-power electronics. First, tunnel field-effect transistors (TFETs) based on InP/GaAs heterostructure nanowires with n-i-p doping profile are explored. To further enhance the interband tunneling current
