  1. 1. The visibility of stellar transients in the Galactic Centre

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

    Author : Jonathan Ström; [2024]
    Keywords : Physics and Astronomy;

    Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

  2. 2. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  3. 3. Common Envelope Evolution

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Robert Wissing; [2016]
    Keywords : Physics and Astronomy;

    Abstract : We present simulations done on the onset of common envelope evolution with giant donors by taking into account the mass loss through the outer Lagrange point and the forming of the common envelope. In addition we apply proper stellar models and evolve our simulations using an Runge-Kutta integrator with adaptive step-size. READ MORE

  4. 4. Analysis of a Low Energy Building with District Heating and Higher Energy Use than Expected

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Ander Arrese Foruria; [2016]
    Keywords : Energy; Ventilation; District Heating; residential Buildings; Envelope;

    Abstract : In this thesis project, a building in Vegagatan 12, Gävle has been analysed. The main objective has been to find why it consumes more energy than it was expected and to solve theoretically the problems.This building is a low energy building certified by Miljöbyggnad which should use less than 55kWh/m2 year and nowadays it is using 62.23 kWh/m2.

  5. 5. Efficient Volvo Bus Cooling System,Using Electrical Fans : A comparison between hydraulic and electrical fans

    University essay from KTH/Kraft- och värmeteknologi

    Author : Rita Fernandes; [2014]
    Keywords : hydraulic fan cooling system; electrical fan drive system; radiator; fan efficiency; fan shroud; static pressure; oil cooler; charge air cooler; built-in-resistance;

    Abstract : Economical and environmental factors together with energy policies towards more efficient systemsare the driving force for the development of the vehicle industry. Significant changes have beenmade to fulfill new emissions legislation but the basic internal combustion vehicle architecture hasbeen kept. READ MORE
