1. 1. Automatic identification of Short Large-Amplitude Magnetic Structures (SLAMS) using Cluster data

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Linn Mandell; [2020]
   Keywords : ;

   Abstract : Short Large-Amplitude Magnetic Structures (SLAMS) are areas in the solar wind with increasedmagnetic field strength in comparison to the background magnetic field. In this thesis they are definedas structures with a magnetic field strength 2.5 times greater than the background magnetic field duringa short time duration. READ MORE

3. 2. Full Physics Orbital Simulation around Comet Didymos for CubeSat MissionAPEX on HERA, ESA

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jonas Zbinden; [2020]
   Keywords : ;

   Abstract : We investigate the dynamic environment of the double asteroid system (65803) Didymoswith its satellite Didymos B for stable trajectories of more than 30 days for a model cubesatcalled APEX, foreseen to visit Didymos with the HERA mission, to be launched in 2023.We find semi-stable orbits with lifetimes up to 15 days under the influence of solar radiationpressure.

4. 3. Accessibility Studies of Potentially Hazardous Asteroids from the Sun-Earth L2 Libration Point

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : GAUTHAM GANESAN; [2020]
   Keywords : Near-Earth Objects; Potentially Hazardous Asteroids; Halo Orbit; Invariant Manifolds; Analytical construction; Palermo Scale; Low-Energy transfer;

   Abstract : A newly proposed F-class mission by the European Space Agency (ESA) in 2019,Comet Interceptor, aims to dynamically intercept a New Solar System Objectsuch as a Dynamically New Comet (DNC). The Spacecraft will be placed in aperiodic (Halo) orbit around the Sun-Earth L2 Lagrangian point, waiting for furtherinstructions about the passage of a comet or an asteroid, which could well bereached within the stipulated mission constraints.

5. 4. Integration Policies and Real Integration : A study of Moroccan immigrants in the Valencian Community in Spain

   University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

   Author : Nahyma Yusseff-Vanegas; [2020]
   Keywords : Migration - Integration -Moroccan Immigrants - Spain Immigrants – Measurement indicators - Model of Domains.; Migración - Integración - Inmigrantes Marroquies - Inmigrantes España -Indicadores de medición - Modelo de Dominios;

   Abstract : The research on the integration of immigrants has become important during the last decades and the ways of measuring the integration of immigrants became more specific and specialized. In this study, the integration of Moroccan immigrants in the Valencian Autonomous Community of Spain was selected, considering that it is one of the most numerous foreign conglomerates and the one that contribute most to the economy of the Valencian Community.
