Opis: It is proved that a linear surjection ▫$\Phi: \mathcal{A} \to \mathcal{B}$▫, which preserves noninvertibility between semisimple, unital, complex Banach algebras, is automatically injective.

Opis: This paper aims to analyze the difference in financial performance of the different tourism economy activities in Slovenia. The analysis was performed for the period 19952009. We analyzed the financial indicators on the basis of the official company accounts data. The nominal financial data are deflated by the statistical deflator for value of inflation in order to obtain real values of financial indicators over the analyzed years. We included financial indicators that are related to the business performance of enterprises in the Slovenian tourism economy. The research hypothesis was tested using quantitative analysis employing nonparametric Kruskal-Wallis test and Wilcoxon-Mann-Whitney test of the secondary data used. The empirical analysis confirmed that there are significant differences in financial performance among different tourism economy activities in Slovenia.

Opis: This paper addresses the problem of damage identification in beam-like structures on the base of bending frequency changes. The identification of damage location and its depth is performed by use of regression relations between changes in natural frequencies and damage parameters. Input data for establishing the regression relations are collected using numerical analysis (FEA) of the beam structure with and without damage. The damage is simulated as a narrow open notch perpendicular to the beam axis. The efficiency and limitations of the proposed technique are assessed through a series of damage scenarios.
Ključne besede: damage identification, finite element analysis, nonlinear regression
