  1. 1. Developing an Automated Drivability Index for Swedish Roadways

    Master-uppsats, KTH/Transportplanering

    Författare :ANDREI DAVID RADU; [2023]
    Nyckelord :;

    Sammanfattning : The masters thesis aims to determine a method to understand which road segments could pose safety risks or where Level 4 autonomous vehicles would operate poorly in the Swedish road context. This vehicle’s ability to operate adequately can be defined as ‘drivable’. LÄS MER

  3. 2. The mechanism behind internal injector deposits

    Master-uppsats, KTH/Kemiteknik

    Författare :Jenny Blomberg; [2023]
    Nyckelord :Biodiesel; deposit formation; engine oil; calcium sulphate; internal diesel injector deposits; Biodiesel; beläggningsbildning; motorolja; kalciumsulfat; interna dieselinjektorbeläggningar;

    Sammanfattning : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets  körbarhet. LÄS MER

  4. 3. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonatan Gustafsson; [2021]
    Nyckelord :MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

    Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER

  5. 4. Probabilistic Assessment of Pile Drivability in Swedish Soils

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :MAEDEH ALINEJAD KORDMAHALLEH; [2020]
    Nyckelord :Pile refusal; Monte Carlo method; probabilistic model; boulder.;

    Sammanfattning : Site investigations are often performed prior to the design of pile foundations with the aim to collect data regarding soil properties including boulder content. The obtained data is typically limited due to non-homogeneous characteristic of the soil. LÄS MER

  7. 5. Drivbarhet av spont i friktionsjordar

    M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Daniel Rehnström; Henrik Olsson; [2018]
    Nyckelord :;

    Sammanfattning : In today’s way of installing a sheet pile in a non-cohesive soil, there is no well-known way to determine whether a sheet pile will be difficult driven or easily driven, based from the ground assessment made for each project (MUR). TESPA has concluded that driving speed of a sheet pile lower than 8 mm/second or 230,4m installed sheet piles per day defines drivability as difficult. LÄS MER
