The Assessment of Level of Flash Floods Threat of Urbanised Areas
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017 Flash floods (or torrential rain flooding) is another type of flood hazard which has caused casualties and significant property damages. A methodology for identification of urban areas, which can potentially be burdened by that type of flood hazard, was ...

The additivity of porosity ideals [PDF]
Proceedings of the American Mathematical Society, 1996 We show that several σ \sigma -ideals related to porous sets have additivity ω 1 \omega _1 and cofinality 2 ω 2^\omega . This answers a question addressed by Miroslav Repický.
