  1. 11. Spectroscopic model characterisation of hot exoplanet atmospheres

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Elin Sandvik; [2022]
    Nyckelord :Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Sammanfattning : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. LÄS MER

  3. 12. C/O+ charge transfer & the Olson-Demkov model

    Master-uppsats, Uppsala universitet/Teoretisk astrofysik

    Författare :Kristoffer Bengtsson; [2021]
    Nyckelord :Astronomy; Charge transfer; rate coefficient; Carbon; Oxygen; energy defect; spectral modelling; supernovae;

    Sammanfattning : Charge transfer reactions and their rates play a key role in correctly estimating element abundances in astrophysical objects such as supernovae. The reaction $C + O^+ \rightarrow C^+ + O(^1D) + \Delta E$ has been shown to be of significance when estimating oxygen abundances through model spectrum evaluations, and the relative rate of this reaction can under certain circumstances completely dictate the neutralization rate of oxygen ions.

  4. 13. Multiple fly-by for interplanetary missions

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Javier Chivite Sierra; [2021]
    Nyckelord :;

    Sammanfattning : Current state-of-the-art of propulsion system for space vehicles does not allow to deliver therequired payload for the mission to all bodies in the Solar System. Therefore, alternatives havebeen developed to reach those bodies without having the necessary technology. LÄS MER

  5. 14. Simultaneous Bayesian parameter estimation and particle-tracking including calculation of mis-linking probabilities

    Magister-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Lennart Golks; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Since 1994 super-resolution microscopes enable us to visualize processes in the nanome- ter regime where bio-molecules work. Consequently, there is a great need for methods analyzing the generated data to transfer the motion of molecules, seen as white dots, into trajectories. LÄS MER

  7. 15. Concept Design Improvement of Shift Fork for New Dog Clutch Actuator : Simulation driven product development approach

    Master-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Nirmal Srinivasan; [2021]
    Nyckelord :Product development; Dynamic analysis; Equivalent-static load; Finite Element Method; Fatigue analysis; High-Pressure Die Casting; Computer-Aided Engineering; Computer-Aided Design; Topology optimization.;

    Sammanfattning : Kongsberg Automotive is developing a brand-new actuator for engaging and disengaging a clutch for different driveline applications. This master thesis research improves the concept design of the shift fork for the new Dog-Clutch Actuator using Design for Manufacturability (DFM). LÄS MER
