  1. 16. Copula approach to fitting bivariate time series

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Jun Wang; [2023]
    Nyckelord :VaR; Copula; ARMA-GARCH; Extreme Value Theory; GPD; Hill estimator; Mathematics and Statistics;

    Sammanfattning : We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. LÄS MER

  3. 17. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

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

    Författare :Anthony Gundstedt; [2023]
    Nyckelord :drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

    Sammanfattning : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. LÄS MER

  4. 18. Evaluating the use of Brush and Tooltip for Time Series visualizations: A comparative study

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :André Eklund; Sebastian Helin; [2023]
    Nyckelord :Time series visualisations; time series visualizations; Tooltip; Brush; Graphical Perception; Estimation Time; Accuracy; Line chart; Bar chart; Time series;

    Sammanfattning : This study uses a combination of user testing and analysis to evaluate the impact of brush and tooltip on the comprehension of time series visualizations. Employing a sequential mixed-methods approach, with qualitative data from semi-structured interviews used to inform the design of a visualization tool, followed by a quantitative user study to validate it.

  5. 19. 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. 20. Ingen skillnad i rörelseekonomi mellan modern stakning och gammeldags stakning, trots stora biomekaniska skillnader

    Kandidat-uppsats,

    Författare :Wilma Fjordell; [2022]
    Nyckelord :Cross-country skiing; double poling; vertical displacement; poling cycles; Längdskidåkning; stakning; vertikalförskjutning; stakcykler;

    Sammanfattning : Syfte Undersöka biomekaniska och fysiologiska skillnader mellan modern och gammeldags stakteknik vid konstant submaximalt arbete på rullskidor. Metod Tolv manliga elitskidåkare rekryterades till studien (ålder: 21 ± 4 år, längd: 183,6 ± 9,3 cm, och vikt: 77,8 ± 10,3 kg). LÄS MER
