  1. 1. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Amanda Byström; [2022]
    Keywords : Milky Way; Galactic archaeology; halo; photometric metallicities; stellar catalogue; Gaia-Enceladus-Sausage; Sagittarius; Pristine survey; metallicity; Gaia mission;

    Abstract : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. READ MORE

  3. 2. Validation of An Iteration Free Material Model for Paperboard (NEO)

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Samuel Thomas Staines; [2022]
    Keywords : Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Abstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE

  4. 3. Simultaneous Bayesian parameter estimation and particle-tracking including calculation of mis-linking probabilities

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Lennart Golks; [2021]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

  5. 4. Development of model to simulate embossing of tissue paper: Effect of embossing on mechanical performance of tissue

    University essay from KTH/Hållfasthetslära

    Author : Ali Khan; [2021]
    Keywords : Tissue paper; Embossing; Model; FEM; Mjukpapper; Prägling;

    Abstract : Tissue paper is a type of soft, absorbent, and lightweight paper with several applications for hygiene and kitchen use. Embossing is an operation during the converting stage of the tissue production process which creates relief designs on tissue. READ MORE

  6. 5. Detection of in-plane orbital manoeuvres from a catalogue of geostationary objects

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Phuong Linh Ngo; [2020]
    Keywords : manoeuvre detection; geostationary orbit; perturbations; filters; Two-line elements; station keeping;

    Abstract : The number of man-made space objects is dramatically growing nowadays. The continuous monitoring and studying of these objects are necessary to keep their number under control and ensure safe space operations. READ MORE
