  1. 16. Wave Energy Concept Benchmarking

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Petter Larsson; Gustaf Rudbeck; [2021]
    Keywords : Budal K; Linear waves; Oscillating water column; Point absorber; Wave energy; Budal K; Linjära vågor; Oscillating water column; Point absorber; Vågenergi;

    Abstract : Denna rapport ämnar undersöka de vanligast förekommande typerna av teknologier för vågkraftverk (eng. Wave Energy Converter, WEC) teknologier för att jämföra de olika konceptens förmåga att absorbera vågenergi. Koncept som undersöks är punktabsorbatorer och oscillerande vattenkolumner. READ MORE

  3. 17. Investigation of Light and Ultrasound Injected Signals in Microphones

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Robin Djerv; [2021]
    Keywords : LightCommands; DolphinAttack; MEMS Microphone; Signal Injection; Security;

    Abstract : Voice commanded systems (VCS) have been proved to be vulnerable to signal in- jections mimicking voice commands and explored security flaws in market avail- able products for the time of each respective study. Signal injection caused with the help of amplitude modulated ultrasonic waves (being known as DolphinAt- tacks - DA) were proved to work on several such devices in 2017. READ MORE

  4. 18. Impact of Covid-19 Response Strategies on the Rate of Change in Mortality in Europe During the First and Second Waves: A Retrospective Cohort Study

    University essay from Uppsala universitet/Internationell mödra- och barnhälsovård (IMCH)

    Author : Nicole Quattrini; [2021]
    Keywords : global health; epidemiology; covid-19; sars-cov-2; non-pharmaceutical interventions;

    Abstract : The coronavirus disease 2019 (COVID-19) has led to more than 3,000,000 deaths globally. During the first year of the pandemic, countries have focused their response strategies on non-pharmaceutical interventions (NPIs) such as lockdowns and use of facial coverings. READ MORE

  5. 19. Quantifying nitrogen oxides and ammonia via frequency modulation in gas sensors

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Marcos Freitas Mourao dos Santos; [2021]
    Keywords : Nitrogen oxides; nox; ammonia; sic-fet; PLSR; quantification;

    Abstract : The use of Silicon Carbide Field Effect Transistor (SiC-FET) sensors in cyclic operation is a proven way to quantify different gases. The standard workflow involves extracting shape-defining features such as averages and slopes of the sensor signal. READ MORE

  6. 20. Tunnel Seismic Prediction in Stockholm Bypass

    University essay from KTH/Jord- och bergmekanik

    Author : Matilda Wessén; Janita Österberg; [2021]
    Keywords : Tunnel Seismic Prediction; TSP; Seismic waves; Stockholm Bypass; Geological mapping; Measurement While Drilling; Tunnel Seismic Prediction; TSP; Seismiska vågor; Förbifart Stockholm; Bergkartering; Measurement While Drilling;

    Abstract : Tunnel Seismic Prediction (TSP) is a geophysical investigation method used to predict the rock conditions ahead of the tunnel face. The method has been used in different types of rock and rock conditions. READ MORE
