1. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

2. Acoustic Characterization of Catalyst
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. READ MORE

3. Road traffic noise simulations based on 3D city models
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years.
