  1. 1. Holistic Assessment of Critical Infrastructure Resilience during Disasters (HACIRD) - A case study of the 2023 Kahramanmaras earthquakes

    Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Erik Kimblad; [2024]
    Nyckelord :Critical infrastructure; Lifeline; Resilience; Interdependencies; Earthquake; Natural hazards; Turkey; Holistic; Disaster; Framework; Assessment; Empirical; Case study; Technology and Engineering;

    Sammanfattning : On February 6, 2023, two earthquakes (7.8MW and 7.7MW) struck Turkey within nine hours, resulting in over 50,000 fatalities and significant damage to critical infrastructures (CI) which provide services essential for the functioning of society. LÄS MER

  3. 2. LEO Satellite Connectivity for flying vehicles

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

    Författare :Jinxuan Chen; [2023]
    Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  4. 3. Development of Radon Detectors for Earthquake Prediction

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alma Partos; Astrid Schöldström; [2023]
    Nyckelord :Radon; earthquake; gamma ray spectroscopy;

    Sammanfattning : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

  5. 4. Keep Calm and Carry On: An empirical study of how firms can build resilience towards supply chain disruptions in a globalised world

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Hedda Cederlund; Cecilia Lindström; [2023]
    Nyckelord :Supply chain disruptions; Supply chains; Resilience; Financial flexibility; Covid-19;

    Sammanfattning : Supply chains are navigating through an evolving environment where an increasing number of disruptions occur, in magnitudes reinforced by globalisation. Covid-19 revealed the vulnerability inherent in the interconnected global supply chain networks and unveiled the unpreparedness of firms to effectively manage the disruption's adverse effects.

  7. 5. Evaluating reliability and limitations of disaster loss accounting databases

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Rebecca Crisanti; [2023]
    Nyckelord :Database; loss data; extreme event; natural hazards; measuring losses; Latin America; EM‐DAT; DesInventar.; Earth and Environmental Sciences;

    Sammanfattning : Disaster loss accounting is an essential tool for assessing the effects of disasters and creating policies for disaster risk reduction that are supported by data. This study compares disaster data for two of the most used disaster loss accounting databases, EM-DAT and DesInventar in the context of six Latin American countries, namely, Uruguay, Chile, Costa Rica, Nicaragua, Honduras, and Venezuela.
