  1. 1. Design and Analysis of Non-symmetric Satellite Constellations

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

    Författare :Jomuel Danilo Costales; [2023]
    Nyckelord :Space; Satellite; Constellation; Coverage; Non-symmetric; Walker; Set Cover problem; Greedy algorithm; Space; Satellit; Constellation; Täckning; Icke-symmetrisk; Walker; Set Cover problem; Greedy algoritm;

    Sammanfattning : Satellite constellation design has been a well-studied problem since the beginning of the space age. In recent years new concepts and approaches tried to solve it with fewer satellites whilst guaranteeing coverage to the areas of interest, whether globally or regionally. LÄS MER

  3. 2. Study of Corner and Bathtub Attachments with Respect to Static Sizing

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Linus Malm; [2022]
    Nyckelord :Applied Mechanics; Solid Mechanics; FEM; Static Strength; Abaqus; Fittings; Failure Modes;

    Sammanfattning : This master thesis studied the possibilities of implementing new handbook methodologies for sizing of corner and bathtub attachments with respect to static strength.  Parametric studies of corner and bathtub attachments were performed in order to examine the effect of boundary conditions and vital dimensions with respect to static strength.

  4. 3. Structural Assessment of the Glulam Arches at Stockholm Central Station

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Anders Naumburg; Kasper Krönlein; [2020]
    Nyckelord :Wood; Glulam; Glulam-arch; Hetzer system; Töreboda system; AB Fribärande träkonstruktioner; Curved I glulam cross-sections;

    Sammanfattning : The purpose of this master’s thesis was to investigate if suspension of heavy objectsis possible in the glulam arches at Stockholm Central Station. The main goal was todetermine the arches’ load carrying capacity’s utility ratio, in order to give knowledgeif additional loading can be added. LÄS MER

  5. 4. Development of synthetic methodology for non-symmetric fullerene dimers

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Fredrik Barnå; [2019]
    Nyckelord :fullerene; dumbbell; Prato; rhodium catalysis; fullerene dimer; HPLC; amino acid; cyclo addition; alkylation; solubility;

    Sammanfattning : This bachelor thesis covers the initial development of a synthesis of fullerene dimers using two different types of linking reactions. Different setups for [3+2] cycloadditions to fullerenes (Prato reaction) were tested, and for that purpose, an N-alkylated amino acid was synthesised. LÄS MER

  7. 5. Combinatorics of Macdonald polynomials and cyclic sieving

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Joakim Uhlin; [2019]
    Nyckelord :;

    Sammanfattning : In this thesis, we study the non-symmetric Macdonald polynomials E_λ (x;q,t) at t=0 from a combinatorial point of view, using the combinatorial formula found by J. Haglund, M. Haiman, and N. Loehr. LÄS MER
