  1. 1. Influence of strain and point defects on the Seebeck coefficient of thermoelectric CoSb3 : Inverkan av töjnings och punktdefekter på Seebeck-koefficienten för termoelektrisk CoSb3

    Master-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Ibrahim Awala; [2021]
    Nyckelord :Cobalt antimonide; Thermoelectric; Strain; Seebeck coefficient; oxidation; DFT; DFT-MD;

    Sammanfattning : Many studies and experiments have been conducted over the years to find solutions to the electricity problem. This issue is not just related to how fossil fuels are dispensed. Also, the environmental concerns associated with using fossil fuels have become a severe issue, which is a major cause of environmental pollution and ozone layer damage. LÄS MER

  3. 2. DAGSLJUSINSLÄPP MED LÅG ENERGIFÖRLUST I FLERBOSTADSHUS : Fallstudie av lägenhet på Bäckby Torggatan 8 i Västerås

    M1-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Merry Karabedian; Maria Hanna; [2021]
    Nyckelord :Daylight factor; energy balance; window; daylight transmittance; shading coefficient; energy requirements; solar heat gain;

    Sammanfattning : Purpose: This degree project aims to study how different choices regarding the size, location and type of windows affect daylight entry in an apartment building in Västerås. We have chosen to calculate the energy requirement when changing the window type, size and shielding factor. LÄS MER

  4. 3. Methodology for estimating thermal performance of buildings for better planning and energy efficient investments

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Waqar Khan; [2020]
    Nyckelord :;

    Sammanfattning : This master thesis aims to find a method to separate the household-electricity usage fromheating-electricity and to estimate the thermal performance of buildings using the datasetavailable. The dataset includes electricity consumption of buildings, number of occupants, typeof heating system, climate data (temperature, wind speed etc. LÄS MER

  5. 4. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Chen Xu; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. LÄS MER

  7. 5. CFD on Open Wet Cutch to Reduce Drag Losses

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Rimmie Duraisamy; [2017]
    Nyckelord :transmission; clutch; multiphase CFD; grooves; oil dissipation; drag losses; transmission; koppling; Multifas-CFD; spårmönster; undanträngning av oljan; strömningsförluster;

    Sammanfattning : As the need for highly efficient transmission systems increase, it is imperative to have lower fuel consumption levels. Hence, it becomes crucial to investigate and understand reasons behind various losses occurring within the system. Clutches and gears contribute to the major losses within a transmission system.
