  1. 11. Mean Motion Resonances and Planetary Scattering

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

    Författare :Erik Dahlöf; [2018]
    Nyckelord :mean motion resonance; orbit resonance; planetary dynamics; planet-planet scattering; planetary scattering; eccentricity; inclination; planet systems; disturbing force; orbit dynamics; orbital elements; planets; exoplanets; scattering phase; relaxation; dynamical instabilities; N-body; protoplanetary disk; planet migration; eccentricity damping; inclination damping; planet-disk interactions; Physics and Astronomy;

    Sammanfattning : The observed distribution of giant exoplanet eccentricities and inclinations are significantly larger than what is measured for their Solar system analogues, Jupiter and Saturn. Since the first observations of exoplanets, planet-planet scattering has been proposed as a possible mechanism for exciting the eccentricities and inclinations of giant exoplanets. LÄS MER

  3. 12. Forbidden oxygen in the Milky Way disk

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Asma Sahli; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Oxygen is produced inside massive stars and dispersed into the interstellar medium mainly through type II supernovae explosions. This element, which is the third most abundant one in the Universe, plays an important role in tracing the Galactic chemical history and evolution. LÄS MER

  4. 13. Feasibility study of battery storage installed with solar PV in an energy efficient house

    Master-uppsats, KTH/Energiteknik

    Författare :MARIA LETIZIA FASCÌ; [2017]
    Nyckelord :PV battery system; battery control; self-consumption; economic analysis.;

    Sammanfattning : The aim of this project is to nd the optimal size battery for an already installed PV system in a family house in Southern Sweden. First, the existing system is modelled and validated. Then a new model including a battery is built. In this model it is assumed that the aim of the battery is to maximize the self-consumption of the house. LÄS MER

  5. 14. IDENTIFIERING AV ELEKTRONIKSKROT

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ahmed Alhamarna; Simon Kjellgren; [2017]
    Nyckelord :RFID;

    Sammanfattning : This report is the result of a survey carried out by two students at Halmstad University. The study was conducted at the request of the recycling company, with the purpose to explore opportunities for streamlining the screening pro- cess of electronic waste products. LÄS MER

  7. 15. Näsandning under högintensiv idrottsprestation och upplevd ansträngning : En experimentell studie om näsandningens effekt på Crossfit-atleter

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Sanna Granström; [2017]
    Nyckelord :;

    Sammanfattning : Background: Breathing is necessary for all human life, in order to give oxygen to muscles and to release energy by oxidation of nutrients. Breathing becomes even more important during physical activities, and especially during high intensity training. One training method that has grown in popularity during the 21st century is Crossfit.
