  1. 21. Energy System Analysis of thermal, hydrogen and battery storage in the energy system of Sweden in 2045

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Poornima Sundarrajan; [2023]
    Nyckelord :VRES; Energy System Model; CEEP; Wind integration; Thermal Energy Storage; Hydrogen Storage; Heat Pumps; Electrolysers; VRES; Energisystemmodell; CEEP; Vindintegration; Värmeenergilagring; Vätgaslagring; Värmepumpar; Elektrolysörer;

    Sammanfattning : Sweden has goals to reach net-zero emissions by 2045. Although electricity sector is almost fossil free, industry & transport still rely on fossil fuels. Ambitious initiatives such as HYBRIT, growth of EV market & expansion of wind power aim to expedite emission reduction. LÄS MER

  2. 22. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Alice Fracchia; [2023]
    Nyckelord :Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

    Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

  3. 23. The potential nitrous oxide emissions in a permanent grassland chronosequence

    Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sandra Lillsjö Kronblad; [2023]
    Nyckelord :nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

    Sammanfattning : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

  4. 24. Kartläggning & optimering av externa flöden ur ett hållbarhetsperspektiv : En fallstudie på Gestamp HardTech

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Malin Norgren; Elin Lindberg; [2023]
    Nyckelord :Sustainable transport; Vehicle emissions modeling; Truck emissions; Vessel emissions; Train emissions; Air pollution modeling; Future vehicles;

    Sammanfattning : In the pursuit of sustainable development, the transportation sector plays a crucial role by significantly contributing to greenhouse gas emissions. The purpose of this study is to examine how companies utilizing third-party logistics can compile and reduce transport-related emissions, more specifically investigating short- and long-term opportunities for the external flow of Gestamp HardTech in Luleå.

  5. 25. En grönare järnväg

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Peder Winblad; [2023]
    Nyckelord :Järnväg; Greenwashing; Emissioner; Klimatsmart; Miljöarbete; Utsläppsberäkning; Pedagogik; Miljöförorening; Formelutveckling; Banvall; Räls; Sliper; CO2; Technology and Engineering;

    Sammanfattning : Detta arbete är en utredning av hur järnvägskonstruktionens emissioner ser ut vid anläggning. Den samlade datan har översatts i ett matematiskt uttryck som ger ett minsta årtal för när en neutraliseringshorisont för projektet kan nås. LÄS MER
