  1. 1. Hydrogen Pipeline Infrastructure Design for Germany in 2045

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Flora Marianne von Mikulicz-Radecki; [2023]
    Keywords : Hydrogen Transport Infrastructure; Pipeline Networks; Retrofitting; Infrastructure Planning; Peak Hour Hydrogen Demand; Utilization Rate; Costs of Avoided Emissions; Carbon Neutrality; Infrastruktur för vätgastransport; rörledningsnät; eftermontering; infrastrukturplanering; efterfrågan på vätgas under m;

    Abstract : Germany’s commitment to carbon neutrality by 2045 underscores the need for climate action, with hydrogen’s multiple uses in industry, transport, and energy offering a viable solution. Efficient retrofitting of the extensive natural gas pipeline network can enable hydrogen to be transported from supply to demand centers. READ MORE

  3. 2. En entrégestaltning med dagvattenlösningar samt vegetationsval : ett samarbete mellan en landskapsingenjör och en trädgårdsingenjör

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Johanna Jacobsson; Emma Olsson; [2023]
    Keywords : gestaltning; regnbädd; dagvattenhantering; dagvattenlösninga; dagvattenberäkningar; vegetation;

    Abstract : Det här arbetet sammanfattas under 15 högskolepoäng, där vi är två skribenter från två olika kandidatprogram. Trädgårdsingenjörsprogrammet - Design samt landskapsingenjörsprogrammet. Vi var intresserade av hur samarbetet mellan våra kompetenser från våra olika utbildningar skulle fungera. READ MORE

  4. 3. Using GPU-aware message passing to accelerate high-fidelity fluid simulations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Wahlgren; [2022]
    Keywords : high-performance computing; computational fluid dynamics; spectral element method; graphical processing units; message passing interface; högprestandaberäkningar; beräkningsströmningsdynamik; spektralelementmetoden; grafikprocessorer; meddelandeförmedlingsgränssnitt;

    Abstract : Motivated by the end of Moore’s law, graphics processing units (GPUs) are replacing general-purpose processors as the main source of computational power in emerging supercomputing architectures. A challenge in systems with GPU accelerators is the cost of transferring data between the host memory and the GPU device memory. READ MORE

  5. 4. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gabriella Corbee; [2021]
    Keywords : Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Abstract : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. READ MORE

  6. 5. Geometry dependency of cerebral arterial pressure, and estimation of wall shear stress in patients with carotid stenosis: a CFD approach

    University essay from Umeå universitet/Institutionen för fysik

    Author : Josef Odevik; [2020]
    Keywords : Carotid stenosis; Geometry dependency; Arterial pressure; Atherosclerosis; Wall shear stress; Computational fluid dynamics; Karotid stenos; Geometriberoende; Artärtryck; Åderförkalkning; Skjuvkraft; Numeriska flödesberäkningar;

    Abstract : This thesis have investigated how the cerebral arterial pressure can be estimated using computational fluid dynamics (CFD). Specifically, a sensitivity study of how the blood vessel diameter affects the arterial pressure in patients with carotid stenosis, has been conducted. READ MORE
