1. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. READ MORE

2. Robust TCO’s for CIGS solar cells based on indium tin oxide
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

3. Study of the Non-Thermal Escape ofDeuterium on Mars : Collisions between Suprathermal Oxygen and Deuterium
University essay from Luleå tekniska universitet/RymdteknikAbstract : Mars’ climate has undergone many massive changes over the course of it’s lifetime. In order toestablish how Mars lost the vast majority of its water, we must be able to understand how Marsis losing its atmosphere today. READ MORE

4. Assessing the relationship between hypoxia and life on Earth, and implications for the search for habitable exoplanets
University essay from Lunds universitet/Geologiska institutionenAbstract : Atmospheric oxygen at the level of present-day Earth (21%) is generally regarded as permissive for the development and survival of complex multicellular life, such as animals. The hypothesis that oxic conditions are conducive for multicellular life has subsequently been applied to the search for life elsewhere in the universe, with planets exhibiting atmospheric oxygen of a similar level to Earth being considered as candidates for habitability.

5. Effects of water-vapor on the Ka/Q band Earth-space radio propagation channel
University essay from Luleå tekniska universitet/RymdteknikAbstract : A higher frequency radio channel both increase the possible data rate and de- crease the required antenna size to efficiently transmit data. Higher frequency also introduce larger weakness to signal loss due to atmospheric effects. Al- phasat satellite conduct experiments for future use of higher frequencies by the Aldo Paraboni Payload.
