  1. 1. Option Pricing using Artificial Neural Networks

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Jan Müller; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Neural networks have an increasingly important role in the financial market, by offering a solution to stationarity and non-linearity whilst also providing robustness and predictive power. Options and option pricing are a fundamental area of interest in the daily activities of investment banks, hedge funds and trading firms in the financial market. LÄS MER

  3. 2. Understanding particulate matter - Material analyses of real-life diesel particulate filters and correlation to vehicles’ operational data

    Master-uppsats, KTH/Kemiteknik

    Författare :Linus Nordin; [2021]
    Nyckelord :Diesel particulate filter; Ash measurement method development; Correlation study; Operational parameters; Principal component analysis; Dieselpartikelfilter; Askanalys metodutveckling; Korrelationsstudie; Driftsparametrar; Principal component analysis;

    Sammanfattning : Syftet med denna studie var att undersöka effekterna av driftsparametrar på ett antal mätbara askrelaterade parametrar i dieselpartikelfilter (DPF) i tunga fordon. Tidigare studier visar att askans packningsdensitet, askflöde och hur askan fördelas inuti ett DPF är beroende av parametrar som temperatur, avgasflöde och oljeförbrukning ett fordon har. LÄS MER

  4. 3. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hesham Sharkas; Haruhi Echigo; [2019]
    Nyckelord :5G; Beamforming; Beam-forming; Beam Management; Beam Searching; Beam Sweeping; Codebook; code-book; Initial Access; MIMO; MillimeterWave; millimeter wave; mmWave; mm-Wave; mm Wave; Precoding; Slepian Beam; Synthesizer; Beam Synthesizer; Technology and Engineering;

    Sammanfattning : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. LÄS MER

  5. 4. Path Planning with Weighted Wall Regions using OctoMap

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Bergström Jerker; [2018]
    Nyckelord :UAV; path planning; A*; wall weights;

    Sammanfattning : In the work of the Control Engineering research group of the Department of Computer Science, Electrical and Space Engineering, Signals and systems at Luleå University of Technology a need had arisen for a path planning algorithm. The ongoing research with Unmanned Aerial Vehicles(UAVs) had so far been done with any complicated paths being created manually with waypoints set by the uses. LÄS MER

  7. 5. Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet

    M1-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Denis Corluka; Samuel Lönnqvist; [2014]
    Nyckelord :Homogena betongelement; Masslag; SS-EN 12354-1; Densitet; Bastian; Ytvikt; Reduktionstal; Luftburet ljud.;

    Sammanfattning : Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. LÄS MER
