  1. 1. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Harald Agelii; [2023]
    Nyckelord :Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

    Sammanfattning : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. LÄS MER

  3. 2. Evaluation of manual and robotic techniques for Micro-RNA extraction in early sepsis diagnosis

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Tjorven Plontke; [2023]
    Nyckelord :;

    Sammanfattning : Sepsis is a life-threatening organ dysfunction caused by the spread of infectious diseases throughout the body, resulting in a dysfunctional immune system response. It includes a wide range of symptomsa ffecting multiple organs, making accurate diagnosis challenging. LÄS MER

  4. 3. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lorenzo Obersnel; [2023]
    Nyckelord :Eneregetic Neutral Atoms; Venus; Ion precipitation; ENA precipitation; Atomi Neutri Energetici; Venere; precipitazione di ioni; precipitazione di atomi neutri; Energisk Neutral Atom; Venus; Utfällningen joner; Utfällningen Energisk Neutral Atom;

    Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER

  5. 4. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hafssa Laabadi; [2023]
    Nyckelord :;

    Sammanfattning : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. LÄS MER

  7. 5. A Longitudinal Perspective on the Implications of the Impaired Fasting Glucose Threshold for Identifying Individuals at Risk of Developing Type 2 Diabetes Mellitus

    Magister-uppsats, Uppsala universitet/Institutionen för folkhälso- och vårdvetenskap

    Författare :Philip Richard Evans; Konstantina Andersen; [2023]
    Nyckelord :Type 2 diabetes mellitus; fasting plasma glucose; impaired fasting glucose; longitudinal trajectory; incidence rate;

    Sammanfattning : Type 2 diabetes mellitus (T2DM) is a global health concern affecting six to ten percent of adults worldwide, with the number of diagnosed individuals projected to double in the next 25 years. However, effective public health strategies can help mitigate its impact on quality of life, morbidity, mortality and the associated social and economic burden. LÄS MER
