  1. 1. 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.

  2. 2. The visibility of double neutron star binaries to LISA

    University essay from Lunds universitet/Astronomi

    Author : Anatole Storck; [2021]
    Keywords : gravitational waves; LISA; neutron stars; orbital simulations; Runge-Kutta method; Physics and Astronomy;

    Abstract : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. READ MORE

  3. 3. 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

  4. 4. 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

  5. 5. Comparing Multistep Methods Within Parametric Classes to Determine Viability in Solver Applications

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Michael Andrew Kraut; [2021]
    Keywords : Ordinary Differential Equations; Initial Value Problems; Linear Multistep Methods; Numerical Analysis; Numerical Solvers; Parametrized; Algorithms; Control Theory; Mathematics and Statistics;

    Abstract : In the 2017 paper by Arévalo and Söderlind, a framework was established for creating linear multistep methods of various classes based on a polynomial formulation which includes variable step size adaptivity. These classes are: k step explicit and implicit methods of order k and k+1 respectively for nonstiff problems (such as Adams methods), and k step implicit methods of order k for stiff problems (such as BDF methods).
