A method is proposed for determining dynamical and observational noise parameters in state and parameter identification from time series using Kalman filters. The noise covariances are estimated in a secondary optimization by maximizing the predictive likelihood of the data. The approach is based on internal consistency; for the correct noise parameters, the uncertainty projected by the Kalman ...

century physiology and his impact upon the development of biology. The questionmark in the title is an indication of the author's uncertainty about this problem. This uncertainty concerns unfortunately the most important aspects of his work; Feurbach's influence upon his philosophy and his place in neo-materialistic physiology with Buchner and Vogt. It was especially hard for her to trace Moles...

making capital and investment is the main driving forces of economic development. based on the investment sensitivity to the changes of some of macro-economic variables and risk and uncertainty, the present study evaluated the effective factors on investment in private sector in iran during 1980-2007. at first, the uncertainty variables of real informal exchange rate, nominal interest rate and ...

In the comparative political economy of rich democracies there is a long tradition of classifying countries into one of a small number of categories based on their economic institutions and policies. The most recent of these is the Varieties of Capitalism project, which posits two major clusters of nations: coordinated and liberal market economies. This classification has generated controversy....

The modelling of river processes involves numerous uncertainties, resulting in uncertain model results. Knowledge of the type and magnitude of uncertainties is crucial for a meaningful interpretation of the model results and the usefulness of results in decision making processes. This case study comprises an uncertainty analysis of the effect of the discharge data used for calibration on the wa...

Der Beitrag untersucht zunächst an den Beispielen des Gesundheitswesens und der Bildung, in welcher Form wir vor, während nun scheinbar auch nach Coronapandemie Maxime Effizienz konstanten Handlungssaufforderung ausgesetzt sind. Gleichzeitig, so sagt die ehemalige deutsche Bundeskanzlerin Angela Merkel, befinden uns gegenwärtig einem Zustand, von Ungewissheit offenem Ausgang geprägt ist ­– stat...

the one-dimensional model of lippincott and schroeder for hydrogen bond has been re-examined and it has been shown that o-h bond distance depends on repulsive van der waals and attractive electrostatic potentials.it has been shown that constant b in the van der waals repulsion potential is not transferable to all hydrogen bonds. the possibility of obtaining the semi-empircal parameters in the l...
