  1. 16. Optimization of a large scale solar installation through virtual storage : Profitability of using the refrigeration system in a grocery store as energy storage

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Erik Larsson; Jesper Sundin; [2019]
    Nyckelord :PV; solar power; virtual storage;

    Sammanfattning : In order to fulfil the goals set by EU and in the Swedish energy agreement an increased share of renewable electricity production, like wind and solar power, is necessary. Due to current legislations photovoltaic (PV) installations are usually limited to the 255 kWp energy taxation rule, or to fit the consumption profile of the building. LÄS MER

  3. 17. An Asymmetric Virtual Reality Game on Water Scarcity

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Sara Egli; Elin Hanstorp; [2019]
    Nyckelord :user centered design; virtual reality; educational games; multiplayer; Technology and Engineering;

    Sammanfattning : Access to water is a necessity for farmers for them to be able to produce food. This poses a problem in Jordan, one of the world’s driest countries, but also in Sweden, where after a drought in the summer of 2018 the state of the water levels was more critical than ever.

  4. 18. Return barriers and their application to stack tracing on modern VMs

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Robert Welin-Berger; [2019]
    Nyckelord :;

    Sammanfattning : Virtual machines are today at the core of a very large portion of the code that runs our everyday lives. Their relative performance and characteristics are of high significance for society indirectly and few other are as impactful as the JVM. LÄS MER

  5. 19. The End of Water Scarcity? : Environmental Determinism and Water Security

    Kandidat-uppsats, Uppsala universitet/Kulturgeografiska institutionen

    Författare :Carina Dios Falk; [2019]
    Nyckelord :Water Security; Development; Technologies; Environmental determinism;

    Sammanfattning :  Is there no development without water? Are arid and dry regions destined to face water scarcity? This essay argues that with globalisation and technological advancements in the water sector are making time and place less relevant for hydro securing societies. Instead, relevant for water insecure countries is the asymmetrical access to technologies and management. LÄS MER

  7. 20. PID tuning with Ant Colony Optimization (ACO) : A framework for a step response based tuning algorithm

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Carl Johan Björk; [2018]
    Nyckelord :PID; self-tuning; control system; building automation; ant colony optimization; neural networks; open-loop; closed-loop; step response.; PID; självtrimning; reglersystem; byggnadsautomation; myrkolonioptimering; neurala nätverk; öppen slinga; sluten slinga; stegsvar.;

    Sammanfattning : The building automation industry lacks an affordable, simple, solution for autonomous PID controller tuning when overhead variables fluctuate. In this project, requested by Jitea AB, a solution was developed, utilising step response process modelling, numerical integration of first order differential equations, and Ant Colony Optimization (ACO).
