Radial Lip Seals Efficiency under Dynamic Operating Conditions

This paper describes experimental and numerical procedures to estimate friction torque on a rotating shaft due to radial elastomeric seals. Two different test rigs have been built, in order to highlight the relationship between the overall friction and the local behaviour of each lip portion in presence of dynamic eccentricities. A direct measurement has been performed with a rotating shaft mac...

Search and Rescue Radar Transponder under Dynamic Operating Conditions

P. Ivančić et al: Search and Rescue Radar... 1. MODEL FOR CALCULATING THE TRANSPONDER’S RADIO HORIZON / Model za izračun radio horizonta odgovarača The radar horizon is typically calculated according to the radio horizon pattern derived from the calculation of the geometric horizon [8]. The geometric horizon (Gh) for the values: r – radius of the Earth ≈ 6378 km or 3440 NM ha – height of aerial...

Thermo-mechanical behavior of EUV pellicle under dynamic exposure conditions

The utilization of EUV pellicles as protective layers for EUV masks requires the use of refractory materials that can tolerate large temperature excursions due to the non-negligible absorption of EUV radiation during exposure. Additionally, the mechanical stress induced on the EUV pellicle by the thermal load is dependent on the thermal expansion of the material which can be responsible for tra...

Avian Influenza Dynamics Under Periodic Environmental Conditions

Since wild birds are the major natural reservoir for all known influenza A viruses, understanding the ecology of avian influenza (AI) viruses circulating in wild birds is critical to predicting disease risk in wild and domestic birds and preventing transmission to humans. AI virus which is shed by infected birds into aquatic environments plays a pivotal role in the sustained transmission of AI....
