  1. 1. Admissibility and Ap classes for radial weights in Rn

    Kandidat-uppsats, Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Författare :Simon Bladh; [2023]
    Nyckelord :Doubling measure; exponent sets; p-admissible weight; Ap-weight; p-Poincaré- inequality; radial weight;

    Sammanfattning : In this thesis we study radial weights on Rn. We study two radial weights with different exponent sets. We show that they are both 1-admissible by utilizing a previously shown sufficient condition, for radial weights to be 1-admissible, together with some results connecting exponent sets and Ap weights.

  3. 2. Design of Aero Engine Mount Structure

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Leon Jörgensen Honarchian Saki; [2023]
    Nyckelord :aero engine mount systems; integration;

    Sammanfattning : This study ventures into the intricate realm of aero engine mount systems, delving into the design and optimization of these crucial components. Our research utilizes mathematical modeling, computational algorithms, and a well-coordinated integration of Python scripting with Computer-Aided Design (CAD) tools to explore the design space of engine mounts, aiming to optimize their performance.

  4. 3. Multibody modelling of the vibrations in an aircraft engine

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

    Författare :Charly Mollet; [2022]
    Nyckelord :Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Sammanfattning : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. LÄS MER

  5. 4. 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

  7. 5. Exponent Sets and Muckenhoupt Ap-weights

    Kandidat-uppsats, Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Författare :Jakob Jonsson; [2022]
    Nyckelord :Capacity; doubling measure; exponent set; integral; measure; Muckenhoupt Ap-weight; p-admissible weight; p-Poincaré-inequality; radial weight; weighted Rn;

    Sammanfattning : In the study of the weighted p-Laplace equation, it is often important to acquire good estimates of capacities. One useful tool for finding such estimates in metric spaces is exponent sets, which are sets describing the local dimensionality of the measure associated with the space. LÄS MER
