  1. 1. COVID-19-pandemins påverkan på lönsamhet och affärsmodeller inom RoPax-sjöfarten

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Fredrik Eliasson; Carl Gustavsson; [2024-02-20]
    Nyckelord :RoPax; Lönsamhet; Affärsmodell; Investerarkommunikation;

    Sammanfattning : Syfte: Syftet med denna studie är att undersöka och få en djupare förståelse av COVID-19 pandemins påverkan på sjöfartsbranschen. Problemdiskussion: Under COVID-19-pandemin drabbades sjöfarten hårt där RoPax drabbades hårdast på grund av segmentets beroende av passagerare. LÄS MER

  3. 2. Simulating Mobility of Large Population using Mobile Application Data

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Mattias Rydström; Diana Salim; [2024-01-23]
    Nyckelord :Human mobility; mobile application data; synthesize activity plans;

    Sammanfattning : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.

  4. 3. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Lisa Linard Pedersen; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. LÄS MER

  5. 4. Beyond the Crisis: A Safe Haven Analysis : Empirical Insights into the Divergence of Gold and Bonds for Portfolio Hedging

    Kandidat-uppsats, Umeå universitet/Företagsekonomi

    Författare :Anthony Baugi; Eugene Zhang; [2024]
    Nyckelord :Gold; Bonds; Safe Haven; Hedging; US Treasury; Volatility; Covid; Portfolio Theory; Asset Dynamics; Fiscal Policy; Monetary Policy; Financial Crisis; Asset Management; Risk Management; Portfolio Risk;

    Sammanfattning : Purpose: This thesis investigates the relationship concerning traditional safe haven assets, gold and US 10-year treasury bonds during periods of market instability, specifically during the economic concerns raised by the COVID-19 pandemic. It assesses the hedging and safe haven properties of these assets and their dynamic nature throughout two periods of unconventional monetary and fiscal policy measures by the Federal Reserve & US Congress respectively.

  7. 5. 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.
