    Author : Anton Åkerström; Sebastian Morel; [2023]
    Keywords : Samgods; Discrete Choice Models;

    Abstract : The primary objective of this thesis is to assess the different statistical methods used forcalibrating the Samgods model, which is a transportation planning tool employed in Sweden toforecast the demand for freight transport. By focusing on the specific context of national logisticsmodels, this research aims to enhance the accuracy and reliability of the Samgods model throughproposed improvements. READ MORE

  2. 7. Autoencoder-Based Likelihood-Free Parameter Inference of Gene Regulatory Network

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Liang Cheng; [2023]
    Keywords : ;

    Abstract : Likelihood-free parameter inference is a well-known statistical methodology that estimates the posterior distribution of model parameters even in cases where the likelihood function is intractable. The performance of this method is highly correlated with the learning of summary statistics, which capture the key features from the high dimensional data such as time series. READ MORE

  3. 8. WSA-ENLIL + Cone ensemble modeling of an Earth-directed ICME : Comparison with in-situ observations by Solar Orbiter and WIND at L1

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Alberto García Ribas; [2023]
    Keywords : ;

    Abstract : Coronal mass ejections (CMEs) are considered the most energetic phenomenon in the heliosphere. Originated in the solar corona, they are formed by ejected plasma driven by strong magnetic fields. READ MORE

  4. 9. Cost Overrun in Swedish Infrastructure Transport Projects : An Analysis of Cost Overrun in Swedish Infratructure Transport Projects between 2010-2022

    University essay from Jönköping University/IHH, Nationalekonomi

    Author : Edwin Sjögren; Jacob Norgren; [2023]
    Keywords : Cost Overrun; Infrastructure Transport Projects; Swedish Infrastructure; Behavioral Economics; Optimism Bias; Strategic Misrepresentation; Cost Estimation; Forecasting;

    Abstract : Cost Overrun is something that plagues infrastructure projects, both in Sweden and globally. The repercussion of it can be severe since it not only hurts the public’s perception of how the public authorities manage and allocates its resources, but also due to the immense opportunity costs that arise when the increased costs need to be covered.

  5. 10. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Mathias Billenberg; [2023]
    Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

    Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE
