  1. 21. Modelling Magnetism of hcp Iron under Earth’s Inner Core Conditions : Based on first-principle DFT calculations and Machine Learning

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Linda Le; [2022]
    Keywords : Machine learning; Earth’s Inner Core; hcp Iron; Electronic structure magnetism; Density functional Theory; Local magnetic moments; Ab initio molecular dynamics; ASD-AIMD-MLLSF simulation;

    Abstract : The structure of Earth’s core remains largely a mystery. The solid inner core is believed to exist in extreme pressure and temperature conditions comparable to 300 GPa and 6000 K and consists mainly of iron, Fe. READ MORE

  2. 22. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  3. 23. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  4. 24. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  5. 25. Testing macroscopic traffic evacuation models for wildland-urban interface fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Adam Ardinge; [2021]
    Keywords : WUI-NITY; WUI; V V; traffic evacuation; WUI fire evacuation; simulation model; verification testing; validation testing; Kincade; Technology and Engineering;

    Abstract : This thesis presents the verification and validation testing performed on the evacuation simulation platform WUI-NITY which has the aim of being a simulation tool for the integration of different layers, such as pedestrian, traffic and wildfire with evolving dynamic interactions. The present thesis aims at applying a set of verification tests and validation testing suitable for WUI-NITY with a focus on the traffic component. READ MORE
