  1. 1. The potential use of black soldier fly larvae residue as a fertilizer

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :An-Marthe Ingelaere; [2023]
    Nyckelord :organic waste; fertilizer; black soldier fly; residue; physico-chemical characteristics; sub-Saharan Africa; socio-economic constraints;

    Sammanfattning : In sub-Saharan Africa (SSA), the primary constraint of agriculture productivity has consistently been ascribed to soil fertility. A common approach to improve soil fertility is the use of fertilizers, both organic and inorganic. Though recently interest is increasing in the use of newer alternatives like biostimulants. LÄS MER

  3. 2. Impact of offtake mechanisms on wind turbine selection and design in North and Central Europe

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

    Författare :Gesa Reiter; [2023]
    Nyckelord :Wind energy; offtake mechanisms; wind turbine configuration and design; rated power; capacity factor; Renewable Energy Sources Act; EEG; PPA; merchant; profitability; NPV; IRR; Vindkraft; upphandlingsmekanismer; vindturbiners konfiguration och utformning; nominell effekt; kapacitetsfaktor; lagen om förnybara energikällor; EEG; energiköpsavtal; handelsprissättning; lönsamhet; NPV; IRR;

    Sammanfattning : Wind power has become a major supplier of electricity in the European market in the last years. In 2020, 13% of electricity generated on the European continent was wind energy (onshore and offshore) and these shares are projected to increase in the next years due to reasons such as climate change and the energy security aspect.

  4. 3. Adjoint optimization of a liquid-cooled heat sink

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Roven Pinto; [2023]
    Nyckelord :Adjoint method; topology optimization; porosity; OpenFOAM;

    Sammanfattning : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. LÄS MER

  5. 4. Renewables and electrification in Europe, A critical analysis

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Thibault Damas; [2023]
    Nyckelord :Electrification; Renewables; Storage; Flexibility; Transmission; Europe; Technology and Engineering;

    Sammanfattning : Electrification of processes has become the cornerstone of the strategy to decarbonise energy supply, especially in recent years. This study aims to define the main issues underlying the electrification of the European energy mix, especially those caused by an increasing share of intermittent energies. LÄS MER

  7. 5. MODELING AND EVALUATING AN INTELLIGENT HEALTH MONITORING SYSTEM FOR ATRIAL FIBRILLATION DETECTION

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Petter Nordin; [2022]
    Nyckelord :;

    Sammanfattning : The heart disease Atrial Fibrillation (AFib) has increased worldwide in recent years. Untreated AFib can lead to cardiovascular complications such as stroke and heart failure. AFib is detected by physicians using Electrocardiogram (ECG). Since this disease can occur without symptoms for some patients, it can lead to late detection. LÄS MER
