  1. 1. Steel-to-concrete connections in narrow concrete corners

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Daniel Carlson Bjernald; Emil Lönn; [2022]
    Keywords : Concrete; steel bolts; concrete failure modes; Abaqus; numerical calculations; concrete cone failure; concrete damaged plasticity; Technology and Engineering;

    Abstract : A commonly occurring problem when designing steel-to-concrete connections in corners with space deficits is the necessity for irregularly placed bolts with regards to design codes. The complexity of the calculations for the irregular placements of bolts generates the need to use simplified models during the design. READ MORE

  3. 2. Data-driven Discovery of Real-time Road Compaction Parameters

    University essay from KTH/Matematisk statistik

    Author : Yuqi Shao; [2022]
    Keywords : statistics; machine learning; road compaction; statistik; maskininlärning; vägpackning;

    Abstract : Road compaction is the last and important stage in road construction. Both under-compaction and over-compaction are inappropriate and may lead to road failures. Intelligent compactors has enabled data gathering and edge computing functionalities, which introduces possibilities in data-driven compaction control. READ MORE

  4. 3. Applying Human-scale Understanding to Sensor-based Data : Generating Passive Feedback to Understand Urban Space Use

    University essay from Uppsala universitet/Byggteknik och byggd miljö

    Author : Adam Eriksson; Hugo Uppling; [2021]
    Keywords : movement data modelling; urban space use; forecasting; time series; space syntax; Prophet; citizen passive feedback;

    Abstract : The aim of this thesis is to investigate how parametrization of large-scale person movement data can contribute to describing the use of urban space. Given anonymous coordinate and timestamp data from a sensor observing an open-air mall, movement-based parameters are selected according to public life studies, behavioral mapping, and space syntax tools.

  5. 4. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Martin Granlöf; [2021]
    Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

    Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

  6. 5. Parametrization of a Lithium-ion battery

    University essay from KTH/Kemiteknik

    Author : Elsa Arksand; [2021]
    Keywords : Parametrization; LiFePO4; Single particle model; Li-ion battery; Pseudo-OCV; Parametrisering; LiFePO4; Singlepartikelmodell; Litiumjonbatteri; Pseudo-OCV;

    Abstract : Batterimodeller används för att representera batterier. För ändamål som batterihanteringssystem används idag främst empiriska modeller som representerar ett batteri med en motsvarande kretsmodell. Några nackdelar för dessa modeller ligger i dess oförmåga att simulera interna tillstånd och en tidskrävande parametriseringsprocess. READ MORE
