  1. 1. Emphysema Classification via Deep Learning

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Olov Molin; [2023]
    Nyckelord :Deep learning; emphysema; CNN;

    Sammanfattning : Emphysema is an incurable lung airway disease and a hallmark of Chronic Obstructive Pulmonary Disease (COPD). In recent decades, Computed Tomography (CT) has been used as a powerful tool for the detection and quantification of different diseases, including emphysema. The use of CT comes with a potential risk: ionizing radiation. LÄS MER

  2. 2. Simulation of Combustion in a Hybrid Rocket Engine

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Oscar Andersson; [2023]
    Nyckelord :Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Sammanfattning : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. LÄS MER

    Sammanfattning : Since 2003, when the first batch of academic Cubesats was launched, 463 of these satellites havereached orbit. The issues faced in the early years were documented and since then the marketof Commercial off-the-shelf components, launch brokers and other auxiliary companies hassky-rocketed. LÄS MER

  4. 4. Influencing factors of posttraumatic growth in breast cancer patients : A descriptive literature review

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för vårdvetenskap

    Författare :Caizhen Huang; Yueyan Qian; [2023]
    Nyckelord :;

    Sammanfattning : WHO(2015) claimed that breast cancer is the most common cancer among women in developed andless developed countries. The number of women diagnosed is much higher in high-income countries likedeveloped countries than in low- and middle-income countries like developing countries, in part becauseearly detection programs are better in developed countries than in developing countries, and becausedeveloping countries lack health care resources and infrastructure, which makes breast cancer treatment achallenge(Taurin & Alkhalifa, 2020).

  5. 5. Monitoring of microclimate underneath agrivoltaic systems using IoT sensor station

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Erik Stridsman; [2023]
    Nyckelord :Agrivoltaics; Microclimate monitoring; IoT; Albedo measurement; Temperature measurement; Humidity measurement; Arduino;

    Sammanfattning : Agrivoltaic systems work on the principle of combining farmland with Photovoltaic energy conversion giving the land it sits on dual purpose. Moreover, by combining solar electricity conversion and crop production additional benefits such as water saving and, in some cases even higher crop yields compared to open field conditions. LÄS MER
