  1. 16. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

    Author : Daniel Kostet; [2018]
    Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

    Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

  3. 17. Trajectory Planning for Off-road Autonomous Driving

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ji Yin; [2018]
    Keywords : ;

    Abstract : The thesis develops a trajectory planner which operates in a formula racing scenario. The proposed trajectory planner gives time-optimal off-road trajectory planning solutions and generates sequences of control signals for the vehicle to follow the trajectory. READ MORE

  4. 18. Immunterapi vid cancer : är blockering av PD-1 en möjlig behandlingsmetod för hund?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Sofia Tengstrand; [2017]
    Keywords : cancer; immunterapi; PD-1; PD-L1; hund; immunotherapy; dog;

    Abstract : Programmed cell death protein 1 (PD-1) är en ko-inhiberande receptor som uttrycks på bland annat T-celler. Vid aktivering av T-celler leder interaktion mellan PD-1 och dess ligand, PD-L1, till att signalering från T-cellsreceptorn inhiberas och T-cellernas effektorfunktioner hämmas. READ MORE

  5. 19. Proof of Concept of Closed Loop Re-Simulation (CLR) Methods in Verification of Autonomous Vehicles

    University essay from KTH/Reglerteknik

    Author : Melih Güldogus; [2017]
    Keywords : ;

    Abstract : This degree project, conducted at Volvo Cars, investigates whether closed-loopre-simulation (CLR) methods can provide a safety proof for the autonomousdriving (AD) functions based on previously collected driving data. The elementsunder study for this closed loop approach are model-in-loop based SimulationPlatform Active Safety (SPAS) environment and Active Safety (AS)software. READ MORE

  6. 20. Analysis and Implementation of an Age Structured Model of the Cell Cycle

    University essay from Lunds universitet/Matematik LTH

    Author : Anna Broms; [2017]
    Keywords : age structured model; cell cycle; cell population dynamics; nonlinear integral equations; Romberg s method; Mathematics and Statistics;

    Abstract : In an age-structured model originating from cancer research, the cell cycle is divided into two phases: Phase 1 of variable length, consisting of the biologically so called G1 phase, and Phase 2 of fixed length, consisting of the so called S, G2 and M phases. A system of nonlinear PDEs along with initial and boundary data describes the number densities of cells in the two phases, depending on time and age (where age is the time spent in a phase). READ MORE
