  1. 1. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

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

    Author : Alexander Adolfsson; [2022]
    Keywords : Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

    Abstract : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. READ MORE

  3. 2. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yifeng Zhong; [2022]
    Keywords : maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE

  4. 3. Test Rig Adaptation for the Investigation of Bearings in Wave Energy Converters

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Aju Sukumaran Menon; [2021]
    Keywords : Test rig; Ocean wave; Oscillating motion; Varying loads; Wave energy converters; Rolling element bearings; Sliding bearing; Scaling; Seawater; Testrigg; havsvåg; Oscillerande rörelse; Varierande belastningar; Omvandlare för vågsenergi; Rullande lager; Glidlager; Skalning; Havsvatten;

    Abstract : Wave ocean energy is a source of renewable energy which is gaining interest in the modern world. In contrast to other well-researched renewable energy sources such as wind energy, wave ocean energy is under the development phase. Governments around the world are encouraging the research of harnessing wave energy. READ MORE

  5. 4. Model on degradation of PEM fuel cells in marine applications

    University essay from KTH/Kemiteknik

    Author : Erik Östling; [2021]
    Keywords : Proton exchange membrane fuel cell PEMFC ; marine applications; durability; lifetime prediction; empirical model; PEM bränsleceller; marina tillämpningar; hållbarhet; livslängdsberäkning; empirisk modell;

    Abstract : Sjöfarten står för 3 % av världens totala växthusgaser och är idag högst beroende av fossila bränslen. Ett alternativ för att gå över till en fossilfri flotta är användning av bränsleceller och vätgas som drivmedel. READ MORE

  6. 5. Prescribing Motion by Mirroring : Using Kinematics from an Individual's Sound Leg in Order to Prescribe the Motion of an Aid

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Marcus Jonsson; [2019]
    Keywords : Biomechanics; Mechanics; Mirroring; Prosthesis; Biomekanik; Mekanik; Protes; Spegling;

    Abstract : Prostheses available today are either passive or active. Active prostheses canapply external energy to the joints, while passive cannot. A well functionalprosthesis that is adapted to the wearer can improve the locomotion and alsodecrease the metabolic cost. READ MORE
