Postdoctoral position on skyglow modeling
The ICA of the Slovak Academy of Sciences, Bratislava, Slovakia, is seeking candidates for a postdoctoral position. The successful candidate will will work for the internal research project “Night sky brightness: modeling and characterization“. The project goals are to theoretically, numerically and experimentally analyze artificial light and sky-glow, and also to characterize light emissions from cities/towns.
Research activities :
- Modeling of multi-physical phenomena in composite materials.
- Development of advanced computational methods for smart materials.
- Development of low-CO2 multicomponent binder materials for special applications.
- Heavy-weight and self-compacting concrete with radiation shielding properties.
- Heat and mass transfer in building materials and structures.
- Modelling of microphysical and optical properties of materials.
- Methods and theory of electromagnetic diagnostics of disperse systems.
NOVEL LIGHTNING THREAT INDICATOR (European patent No. 3105614 has been filed in 2018)
The patent describes a method for determining if there is an increased chance of lightning. Lightning is a threat especially to aircraft launching and landing as a lightning strike can cause loss of power and instrument failure and result in catastrophe. As a safety precaution, airports close during increased lightning threats. Such closures are expensive. Accurately assessing the threat of lightning can save resources, since airports could remain open when there is no threat. Applied meteorology, mainly the use of information about the state of electric charge of water droplets to indicate the lightning threat for various applications.
Research: Retrieval of angular emission function from whole-city light sources
The research performed by our team promises great progress in light-pollution modeling as this is the first time the indirect remote-sensing method, to retrieve the CEF from sky-brightness measurements, has been developed and successfully applied to experimental data.
