   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Kenny Andersson; [2023]
   Nyckelord :space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

   Sammanfattning : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. LÄS MER

3. 2. Feasibility of reintroduction of European Bison (Bison bonasus) to Sweden with focus on traffic accidents

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Michael Topszewski; [2023]
   Nyckelord :wildlife-vehicle collision; risk prediction; reintroduction feasibility; european bison; Bison bonasus; moose; Alces alces; Human-wildlife conflict;

   Sammanfattning : The historical occurrence of European bison (Bison bonasus) in Sweden during the early Holocene emphasizes the ecological significance for a potential reintroduction. The European bison, the largest herbivore on the European continent, is a keystone species with a significant influence on ecosystem dynamics. LÄS MER

4. 3. Simulation of Optical Aberrations for Comet Interceptor’s OPIC Instrument

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Maximilian Bührer; [2020]
   Nyckelord :simulation; camera; lens effects; optical aberrations; optics; ray tracing; sensor noise; coma; astigmatism; chromatic aberration; motion blur; rolling shutter; CMOS; CCD;

   Sammanfattning : In space exploration optical imaging is one of the key measurements conducted, with a vast majority of missions heavily relying on optical data acquisition to examine alien worlds. One such endeavor is ESA’s F-class mission Comet Interceptor, a multi-element spacecraft expected to be launched in 2028. LÄS MER

5. 4. Vehicle Collision Risk Prediction Using a Dynamic Bayesian Network

   Master-uppsats, KTH/Matematisk statistik

   Författare :Jonas Lindberg; Isak Wolfert Källman; [2020]
   Nyckelord :Collision risk prediction; dynamic Bayesian network; sequential importance resampling; autonomous vehicles; ADAS; intelligent driver model; Förutsägelse av kollisionsrisk; dynamiskt Bayesianskt nätverk; sekventiell vägd simulering; autonoma fordon; ADAS; intelligent förarmodell;

   Sammanfattning : This thesis tackles the problem of predicting the collision risk for vehicles driving in complex traffic scenes for a few seconds into the future. The method is based on previous research using dynamic Bayesian networks to represent the state of the system. LÄS MER

7. 5. Evaluation of Prediction Models in Trajectory Planning for Overtaking Maneuvers.

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Linda Truong; [2019]
   Nyckelord :;

   Sammanfattning : Developing autonomous overtaking could enhance safety by more accurate decision making of if, when and how to execute an overtaking and thereby decrease the collision risk caused by the human factor. Trajectory planning is a strategy to plan overtaking maneuvers, where a trajectory is defined as a path containing position, velocity and acceleration information along with time stamps. LÄS MER
