  1. 1. On modelling OMXS30 stocks - comparison between ARMA models and neural networks

    Master-uppsats, Uppsala universitet/Matematiska institutionen

    Författare :Irina Zarankina; [2023]
    Nyckelord :ARMA; ARIMA; LSTM; time series; statistics;

    Sammanfattning : This thesis compares the results of the performance of the statistical Autoregressive integrated moving average (ARIMA) model and the neural network Long short-term model (LSTM) on a data set, which represents a market index. Both models are used to predict monthly, daily, and minute close prices of the OMX Stockholm 30 Index. LÄS MER

  3. 2. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Soraya Hosseinvash Azari; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Sammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER

  4. 3. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Duncan Jones; [2023]
    Nyckelord :Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  5. 4. Increasing ecosystem services at an industrial area : A study applied to Rönnskärsverken

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Lisa Larsson; Petra Ljunggren; [2023]
    Nyckelord :Green areas; Biodiversity; Environmental regulation; Nature Based Solutions; Stormwater management;

    Sammanfattning : What are ecosystem services, what are the possibilities to use them as a solution to remediate environmental problems, and how can they be increased in an industrial area such as Rönnskärsverken? The aim of this master thesis was to investigate the potential and the incentive for increasing ecosystem services in Rönnskärsverken’s industrial area through green areas and nature based stormwater management solutions on the site.  Ecosystem services is a concept that was put on the political agenda in the UN in 2005 in order to create a common definition and valuation to raise awareness of the values that nature provides to human beings.

  7. 5. The Effect of Noise on Grover's Algorithm when Searching with Multiple Marked Items

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

    Författare :William Kågebo; Hannes Stig; [2023]
    Nyckelord :Quantum computing; Grover’s algorithm; Noise; Multiple marked items; Qiskit framework; Kvantberäkning; Grover’s algoritm; Brus; Flera markerade objekt; Qiskitramverk;

    Sammanfattning : This thesis investigates the impact noise has on Grover’s algorithm when being used to search for multiple items in a database. The main metric being looked at is the probability of the algorithm successfully finding a correct item. LÄS MER
