The shot-noise limited sensitivity of Michelson-type laser interferometers with Fabry-Perot arm cavities can be increased by the so-called power-recycling technique. In such a scheme the power-recycling cavity is optically coupled with the interferometer's arm cavities. A problem arises because the central coupling mirror transmits a rather high laser power and may show thermal lensing, thermo-...

The steady-state initialization of large object-oriented thermo-hydraulic networks is a difficult problem, because of the sensitivity of the convergence to the initial guesses of the iteration variables. This paper proposes an approach to this problem based on homotopy transformation, detailing specific criteria for model simplifications in this physical domain. The approach is successfully dem...

Both thermovision and pyrometric measuring are widely used for the control of industrial process thermo modes, the technical service and diagnostics of equipment as well as the works on security and safety provision. The objective of thermovision measuring is the visualization and research of an object thermo field on the basis of temperature gradient identification at defined temperature sensi...

Inverse propensity weighting (IPW) is a popular method for estimating treatment effects from observational data. However, its correctness relies on the untestable (and frequently implausible) assumption that all confounders have been measured. This article introduces robust sensitivity analysis IPW estimates range of compatible with given amount unobserved confounding. The estimated converges t...

In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...
