  1. 1. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Frida Hermansson; [2023]
    Nyckelord :Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

    Sammanfattning : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

  2. 2. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Wenhan Zhou; [2023]
    Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

    Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER

  3. 3. Flexibilitetsresurser för effektutjämning vid Brunna butikslager : En studie av samverkan mellan solenergi, energilager och smart laddning av en elektrifierad fordonsflotta

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :David Bergkvist; [2023]
    Nyckelord :Effekttoppskapning; effektutjämning; flexibilitetsresurser; energihanteringssystem; solenergi; smart fordonsladdning; energilager;

    Sammanfattning : Due to the ongoing climate crisis there is a need for a transition of energy usage. The transition is dependent on electricity as an energy carrier which puts pressure on the electricity grid to develop at the same rate as the electricity demand increases. However, the process of building new transmission lines is expensive and drawn out. LÄS MER

  4. 4. Assessment of a Wearable Motion Analysis System : Predicting ground reaction forces and joint angles with IMU:s and pressure insole sensors

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Norman Mårten; [2023]
    Nyckelord :Ground reaction force; kinematics; pressure insoles; IMUs;

    Sammanfattning : The analysis of human movement is important for diagnosis of as wellas planning and evaluating treatments of disorders or injuries affectingmovement. Optical motion capture combined with force plates provideaccurate measurements, but are confined to laboratory settings limiting theirpotential usefulness in clinical applications. LÄS MER

  5. 5. Prototyping and manufacturing of air-controlled damper unit to improve cooling system operating efficiency for data centers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Peter Nilsson; [2023]
    Nyckelord :data center; cooling; server; design; efficiency; model; design; holistic cooling; cooling system; air cooling; differential pressure; wind tunnel; CRAH; datacenter; luftkylning; modell; design; CRAH; kylning; tryck; vindtunnel; server;

    Sammanfattning : More and more people are using the internet for data processing, transfer, and storage. With it comes a higher demand for computational power from data servers. Unsurprisingly, the data center industry is becoming an increasingly large industry that is important for people’s daily lives. LÄS MER
