Assessing meteotsunami potential of high-frequency air pressure oscillations observed in the middle Adriatic

Vilibić, Ivica; Mihanović, Hrvoje; Charrayre, Francois - In: Natural Hazards 74 (2014) 1, pp. 217-232

High-resolution air pressure series collected from a triangle of middle Adriatic microbarograph stations between April …-minute air pressure tendencies were used to detect an event. Wavelet and cross-wavelet analysis showed that the energies of high … during the cold part of the year. Coherence between stations was normally found at periods longer than 1 h, while air …

The potential of PEM fuel cell for a new drinking water source

Kim, Taeyoung; Lee, Seungjae; Park, Heekyung - In: Renewable and Sustainable Energy Reviews 15 (2011) 8, pp. 3676-3689

The worldwide water scarcity, especially in the developing countries and arid regions, forces people to rely on unsafe sources of drinking water. There is a pressing need for these regions to develop decentralized, small-scale water utilities. However, more than 50% of the total operating costs...
