  1. 1. Modelling and Techno-economic Analysis of a Hybrid CSP/PV System using Solid Oxide Electrolyser for Hydrogen Production

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Chuanyin Tang; [2023]
    Nyckelord :Power to Hydrogen; Solid Oxide Electrolyser; CSP; PV; LCOE; LCOH.;

    Sammanfattning : This project proposes a solar-driven hybrid system for electricity generation and hydrogen production, which includes concentrated solar power (CSP), photovoltaic (PV), solid oxide electrolyser (SOEC). Electricity from the CSP and PV provides a continuous 24/7 supply to meet demand-side power consumption.

  3. 2. Oanvänt material på byggarbetsplatser - Förekomst, hantering och förebyggandet

    Kandidat-uppsats, Lunds universitet/Avdelningen för Byggnadsfysik; Lunds universitet/Avdelningen för Installations- och klimatiseringslära; Lunds universitet/Institutionen för bygg- och miljöteknologi; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Nellie Jepsson; [2021]
    Nyckelord :Oanvänt byggmaterial; miljö; BIM; Building Information Modelling; hållbarhet; kassering; materialavfall; materialhantering; etiska regler; Lean Construction; unused building materials; environment; sustainability; disposal; material waste; material handling; ethical rules; Technology and Engineering;

    Sammanfattning : The purpose of this study is to investigate which contributing factors that leads to unused and waste materials at the construction sites. What can be changed to reduce the amount of unused material and to reduce handling. The material that is over today on the projects, how it’s handled and what strategies are there. LÄS MER

  4. 3. Introduction of UXV assets into naval fleet architectures through an MILP based fleet modelling tool

    Master-uppsats, KTH/Marina system

    Författare :Sjoerd Jan Sinnema; [2021]
    Nyckelord :Numerical cost optimization; Naval fleet modelling; UXV integration; MILP programming; Maritime engineering; Numerisk kostnadsoptimering; flottmodellering; UXV -integration; MILP -programmering; sjöfartsteknik;

    Sammanfattning : The problem of fleet design and fleet modelling; for decades problems regarding determining fleet sizes and optimized routing problems have formed the groundwork into the fleet design and fleet optimization for a wide range of business sectors. In most of these problems only single entities or fixed design resources are optimized for a certain route and delivery objective based on minimizing operational costs. LÄS MER

  5. 4. Modelling and Trajectory Planning for a Small-Scale Surface Ship

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Gustav Zetterqvist; Fabian Steen; [2021]
    Nyckelord :Marine vessel; Ship; Modelling; Model estimation; Trajectory planning; Optimal control;

    Sammanfattning : Autonomous ships are one way to increase safety at sea and to decrease environmental impact of marine traveling and shipping. For this application, a good representation of the environment and a physical model of the ship are vital components. LÄS MER

  7. 5. Development of a 2D Optimal Path Simulation for Ship-to-Shore Cranes : Safe Trajectories within Interchangeable Obstalce Environments

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Rickard Green; [2020]
    Nyckelord :Optimal Path; Control; Control theory; Obstacle; Safe trajectories; LiU; ISY; Reglerteknik;

    Sammanfattning : The most advanced ports as of writing of this report are at least somewhat autonomous. Whether discussing the transporters between crane and stack (temporary storage) or cranes, the ports are shifting into a completely autonomous system. This ultimate goal presents a challenge in regards to unloading and loading cargo ships in the harbour. LÄS MER
