Measurements can not only be used as stand-alone data or for model evaluation. If we trust the measured data and our models sufficiently well, we can use them to infer source properties. The method to do this is called inverse modelling; it is an optimisation technique. Sources (or source parameters) are adjusted so that the differences between model output and measurements are minimised. Inver...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

The paper by Brunner et al. reports on the inverse estimation of hydrofluorocarbon (HFC) and SF6 emissions in Europe exploiting the respective atmospheric concentrations variability measured at three monitoring sites. Four state-of-the-art inverse modelling systems are compared with respect to their performance in modelling the observed concentrations and with respect to their consistency in in...

This paper considers the inverse shortest paths problem where arc costs are subject to correlation constraints. The motivation for this research arises from applications in traac modelling and seismic tomography. A new method is proposed for solving this class of problems. It is constructed as a generalization of the algorithm presented in 1 for uncorrelated inverse shortest paths. Preliminary ...

OBJECTIVE The goal of the study is to use physical modelling of voice production to assess the performance of an inverse filtering method in estimating the glottal flow from acoustic speech pressure signals. METHODS An automatic inverse filtering method is presented, and speech pressure signals are generated using physical modelling of voice production so as to obtain test vowels with a known...

The International Monitoring System (IMS) radionuclide network enforces the Comprehensive NuclearTest-Ban Treaty which bans nuclear explosions. We have evaluated the potential of the IMS radionuclide network for inverse modelling of the source, whereas it is usually assessed by its detection capability. To do so, we have chosen the degrees of freedom for the signal (DFS), a well established cri...
