1. 1. Functional Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Brice Metzinger; [2022]
   Keywords : ;

   Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, an orbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulation of the off-design operation of the cryogenic engine of Nyx. READ MORE

3. 2. Have Radial Velocity Surveys Missed Any Planets?

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Shah Raj; [2021]
   Keywords : radial velocity survey; transit method; exoplanet; habitable zone; habitable zone boundaries; HZ; early Mars; recent Venus; stability; instability; chaos; REBOUND; MEGNO; MEGNO maps; Hill sphere; stable systems; unstable systems; Physics and Astronomy;

   Abstract : The project was aimed at numerically assessing exoplanetary systems to distinguish their capabilities of hosting additional planets. The shortcomings of the radial velocity method sometimes causes hindrance in the detection of terrestrial planets. READ MORE

4. 3. Prussian White In Sodium- Ion Batteries : An evaluation of organic and inorganic coatings on active material particles

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

   Author : Philip Jansson; [2021]
   Keywords : Sodium-ion batteries; Prussian White; Coating; Surface engineering; Zinc oxide; Polyaniline; Natriumjonbatterier; Berlinervitt; Beläggning; Ytmodifiering; Zinkoxid; Polyanilin;

   Abstract : Emerging markets in electrochemical energy storage, such as stationary grid storage, coupled with future concerns over the availability of lithium, places sodium-ion battery (SIB) technologies at a unique position to enter the market as a commercially viable alternative. Current shortcomings in the performance of cathode materials in SIBs would necessarily need to be addressed if this technology is to compete with existing commercial lithium-ion battery counterparts.

5. 4. Modelling And Simulation of Attitude AndOrbital Control For Foresail-2

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Tushar Sharma; [2021]
   Keywords : ;

   Abstract : A central factor affecting spacecraft lifetime is the radiation environment, which isunpredictable due to an incomplete understanding of plasma dynamics. FORESAIL2 will build on the FORESAIL-1 results – measurements of radiation belt lossesand demonstrate deorbiting in LEO. READ MORE

6. 5. 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.
