  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).

  3. 2. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  4. 3. Does the shoe type matter when prescribing custom-made foot orthoses? A comparison of peak plantar pressure in healthy subjects with custom-made foot orthoses in different shoe types.

    Kandidat-uppsats, Jönköping University/HHJ. Ortopedteknisk plattform

    Författare :Erik Wennerholm; Jenny Gustafsson; [2023]
    Nyckelord :shoe design; in-shoe measurement; customized insoles; pressure distribution; inserts; skodesign; inlägg; tryckmätning i sko; tryckfördelning; fotbäddar;

    Sammanfattning : Purpose: A common prescription in Prosthetic and orthotic clinics in Sweden is custom-made foot orthoses (CmFO). These must be placed in shoes. The aim of this study was to investigate whether the shoe type will have an impact on the effectiveness of CmFO regarding plantar pressure (PP). LÄS MER

  5. 4. 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

  7. 5. Support for autonomously driven systems in harsh environments. : Degree project for Master of Science in mechanical engineering with focus on innovation and sustainable product development

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Mohammed Aljafari; [2023]
    Nyckelord :Sensor; Temperature measurement; Maintenance free; Autonomous system; Sensor; Temperatmätning; Underhållsfri; Autonomt system; Design thinking;

    Sammanfattning : Symptoms of harsh environments create pressure on autonomous machines to work wellwith the use of measurement devices. Sensors used within construction equipment vehiclessuffer from being covered with fogs of dirt, oil, water, and dust. LÄS MER
