  1. 1. Mapping the present-day chemical abundance structure of the Solar neighbourhood: O & Si

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Astronomi

    Författare :Kristiina Verro; [2017]
    Nyckelord :astrophysics; stellar spectroscopy; abundance analysis; solar neighbourhood; massive stars; Galaxy; Physics and Astronomy;

    Sammanfattning : Context. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. LÄS MER

  2. 2. Radial migration of stars, measured in N-body simulations

    Master-uppsats, Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Daniel Mikkola; [2017]
    Nyckelord :N-body; simulations; galaxies; radial migration; stars; Physics and Astronomy;

    Sammanfattning : The purpose of Galactic archaeology is determining the history of the Milky Way (MW) Galaxy. To do this one uses observational data from stellar populations in terms of properties such as kinematics, chemistry, ages, and evolution. LÄS MER

  3. 3. It Takes Water and Energy in a Block

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Alvin Hilmersson; Fanny Norén; Alexander Ullén; Lucas Wiik; [2016]
    Nyckelord :Energy Water Greywater Reuse Save Residental;

    Sammanfattning : This report investigates sustainable solutions for electricity and water savings in an urban neighbourhood consisting of a block of buildings in Sege Park, Malmö. The solutions were evaluated in terms of sharing, producing, recycling and saving. LÄS MER

  4. 4. Feasibility study on making Van Maanenblok a near zero energy building urban neighbourhood

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Sriram Krishnamurthy; [2014]
    Nyckelord :near zero energy building; trias energetica;

    Sammanfattning : The rapid exhaustion of the finite reserves of fossil-fuels adds to the woes on all walks of the society, and especially on the policy-makers, scientists and engineers to devise means to mitigate the consequences. Reducing energy demand and grid-dependency by decentralized energy production can help improve energy security of a nation. LÄS MER

  5. 5. Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Prokofiev; [2014]
    Nyckelord :klimatpåverkan; LCA; livscykelanalys; energianvändning i byggnader; samhällsplanering; förnybar energi; emissionsfaktor;

    Sammanfattning : With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions.
