In the context of the transition to a hydrogen-based economy, the assessment of the risks associated with this energy vector is becoming a priority for industrial safety. The unique properties of hydrogen, its high reactivity and high burning rate, require the use of advanced numerical simulation tools, capable of providing highly accurate predictions of the effects of explosive phenomena. This paper presents methodological contributions aimed at optimizing the numerical models used for the analysis of explosions ...

Nowadays the communication is made mainly through electronic devices. These devices produce electromagnetic radiation that influences the quality of the sent signal. Also, health problems are generated due to the time spent in an electromagnetic medium that emits radiations. This paper presents some of latest screen developments regarding electromagnetic screens, advancements in shielding materials.

As is well known, hydrogen exhibits a wide flammability range, low ignition energy, and high diffusivity, which create significant explosion risks in storage and handling facilities. Therefore, the development of effective methods and devices for the detection and control of hydrogen explosions is essential to ensure operational safety. This paper presents the development and experimental validation of an explosion control device intended for hydrogen storage systems. The proposed device is based on an optical ult...

Europe is undergoing a transition toward renewable heating and cooling, and borehole heat exchanger systems play a critical role in this energy shift. However, their efficiency depends heavily on site-specific and local climatic conditions. This study evaluates BHE design and performance across 11 European capital cities that represent diverse climatic conditions, from hot/dry (Nicosia, 21.56 C, undisturbed ground temperature) to cold/humid (Helsinki, 6.76 C). A representative university building was virtually rel...
