  1. 1. The impact of economic sanctions on international trade in High-Tech products and semiconductors

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Simona Semenas; [2023]
    Nyckelord :gravity model; international trade; semiconductors; sanctions; Business and Economics;

    Sammanfattning : In 2018, the United States set in motion a comprehensive series of sanctions, which served as the catalyst for a notable technology and trade dispute. This dispute spanned a wide array of Chinese products, semiconductors among them, and marked a significant turning point in the evolving landscape of international commerce and technological competition.

  3. 2. Pricing and Modeling Heavy Tailed Reinsurance Treaties - A Pricing Application to Risk XL Contracts

    Master-uppsats, KTH/Matematisk statistik

    Författare :Ormia Abdullah Mohamad; Anna Westin; [2023]
    Nyckelord :Reinsurance; Extreme Value Theory; POT-model; Hill estimator; Risk XL contracts; Generalized Pareto distribution; Method of Moments.; Återförsäkring; Extremevärdesteori; POT-modellen; Hill estimatorn; Risk XL kontrakt; generella Paretofördelningen; Momentmetoden.;

    Sammanfattning : To estimate the risk of a loss occurring for insurance takers is a difficult task in the insurance industry. It is an even more difficult task to price the risk for reinsurance companies which insures the primary insurers. LÄS MER

  4. 3. Bayesian Networks for Modelling the Respiratory System and Predicting Hospitalizations

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

    Författare :Victor Lopo Martinez; [2023]
    Nyckelord :Bayesian Networks; Structure Learning; Conditional Probability Tables; Maximum Likelihood Estimator; XGBoost; and Respiratory System; Bayesianska nätverk; Strukturinlärning; Villkorliga sannolikhetstabeller; Maximum Likelihood Estimator; XGBoost; och Andningssystemet;

    Sammanfattning : Bayesian networks can be used to model the respiratory system. Their structure indicate how risk factors, symptoms, and diseases are related and the Conditional Probability Tables enable predictions about a patient’s need for hospitalization. LÄS MER

  5. 4. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Erica Svensson; [2022]
    Nyckelord :Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

    Sammanfattning : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. LÄS MER

  7. 5. Theoretical and numerical aspects of the pattern maximum likelihood estimator, with a view towards symmetric functionals estimation

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Paulina Benthem Ciano; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Suppose that an infinite population is partitioned into different species. Given a random sample from the population of species, we are interested in estimating the species richness, which is the number of different species inhabiting a given area. The species richness is a symmetric functional of the probability mass function. LÄS MER
