  1. 1. The association between obesity, low-grade inflammation, self-reported knee symptoms and radiographic knee osteoarthritis in individuals with knee pain : A longitudinal cohort study

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Alma Buer; [2024]
    Nyckelord :osteoarthritis knee pain; artros knä smärta;

    Sammanfattning : Abstract  Background One of the earliest signs of knee osteoarthritis (OA) is knee pain which correlates with inflammation and disease severity. Knee OA affects 260 million worldwide, and is in similarity with obesity, characterized by ongoing low-grade inflammation. LÄS MER

  3. 2. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Zeyuan Wu; [2024]
    Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

    Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

  4. 3. UPPLEVD TRYGGHET I EN TID AV ESKALERAT SKJUTVAPENVÅLD : En kvantitativ studie över betydelsen av storstadsområden och sociodemografiska egenskaper

    Kandidat-uppsats, Umeå universitet/Sociologiska institutionen

    Författare :Emelie Jäderberg; Maja Palm; [2024]
    Nyckelord :gang violence; gun violence; metropolitan areas; perceived security; shootings; socio-demographics;

    Sammanfattning : Gun violence has increased significantly in Sweden in the past years. The purpose of this study is therefore to investigate whether the number of shootings has an impact on the residents' sense of perceived security in Sweden's metropolitan areas, with the control variables of the socio-demographic characteristics gender, age and education level.

  5. 4. Sömn i relation till vandrande tankar : En kvantitativ kognitionsstudie om spontaneous och deliberate mind wandering

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för psykologi (PSY)

    Författare :Amanda Fransson; Ingrid Unger Frick; [2024]
    Nyckelord :Mind wandering; spontaneous mind wandering; deliberate mind wandering; sömnstörning; ålder; kön;

    Sammanfattning : Människor tenderar att driva iväg i tankarna en stor del av den vakna tiden oavsett vad de företar sig. Vidare uppvisar befolkningen otillräcklig sömn vilket är avgörande för kognitiva förmågan och individers hälsa. LÄS MER

  7. 5. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Elie Roudiere; [2024]
    Nyckelord :Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Sammanfattning : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. LÄS MER
