  1. 1. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

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

    Författare :Jesper Brunnström; [2021]
    Nyckelord :Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Sammanfattning : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. LÄS MER

  2. 2. Konvergens i EU : Trivs Östeuropa i EU-gemenskapen?

    Kandidat-uppsats, Umeå universitet/Nationalekonomi; Umeå universitet/Nationalekonomi

    Författare :Martin Ceder; Gustav Forslund; [2020]
    Nyckelord :;

    Sammanfattning : The EU is a unique project both in scope and design. However at the time of writing they are losing a large member which makes it more relevant to investigate EU. This paper focuses on examining how member states develop in this community and how countries with different backgrounds respond to joining this community. LÄS MER

  3. 3. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Christina Andersen; [2020]
    Nyckelord :alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. LÄS MER

  4. 4. Option pricing models: A comparison between models with constant and stochastic volatilities as well as discontinuity jumps

    Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik; Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Carl Paulin; Maja Lindström; [2020]
    Nyckelord :Financial mathematics; option pricing; calibration; options; parameter calibration; Black Scholes Merton model; Heston model; Bates model; Merton jump diffusion model; Black Scholes;

    Sammanfattning : The purpose of this thesis is to compare option pricing models. We have investigated the constant volatility models Black-Scholes-Merton (BSM) and Merton’s Jump Diffusion (MJD) as well as the stochastic volatility models Heston and Bates. LÄS MER

  5. 5. Standardization and optimization of index for 28 day strength for cement made from standard clinker

    Uppsats för yrkesexamina på avancerad nivå, KTH/Kemiteknik

    Författare :Anton Hermansson; [2020]
    Nyckelord :;

    Sammanfattning : This project regards the prediction of 28 day compressive strengths of cement. Using traditional multivariate analysis in combination with Artificial Neural Networks indexes have been developed which makes these predictions possible. LÄS MER
