  1. 1. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Filip Gustavsson; [2023]
    Nyckelord :Particle Physics; Beyond Standard Model; Two-Higgs Doublet Model; 2HDM; Electroweak Phase Transitions; Strong First-order Phase Transition; Dimensional Reduction; CP-conserving; Softly broken Z2-symmetry; Physics and Astronomy;

    Sammanfattning : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. LÄS MER

  3. 2. Model predictive control in heating and cooling networks : A case study of an urban district in Stockholm

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

    Författare :ANDERS SAMUELSSON; DANIEL STEUER; [2021]
    Nyckelord :;

    Sammanfattning : This work presents a model predictive control system for heating and cooling supply planning in an urban heating and cooling network. The control approach addresses the need for strategic operation of distributed production technologies and thermal energy storage in increasingly complex heating and cooling networks. LÄS MER

  4. 3. Modellering och analys av sekundärvärmesystemet på massa- och pappersbruket SCA Obbola

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jens Norgren; [2021]
    Nyckelord :Sekundärvärme; Massabruk; Pappersbruk;

    Sammanfattning : Syftet med det här examensarbetet var att utreda massa- och pappersbruket SCA Obbolas sekundärvärmesystem. Examensarbetet utredde hur systemet kommer påverkas efter genomfört projekt ”Expansion Obbola” och huruvida fabriken kommer lida av sekundärvärmeunderskott eller inte. LÄS MER

  5. 4. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

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

    Författare :DIYUE WANG; [2020]
    Nyckelord :Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Sammanfattning : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

  7. 5. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies

    Master-uppsats, KTH/Energiteknik

    Författare :Hsin-Ting Ko; [2020]
    Nyckelord :Demand flexibility; Heat pump; IDA ICE; Smart grid; Thermal comfort; Thermal inertia; Bottom-up simuleringsmodell; efterfrågeflexibilitet; Demand response; energiteknologi; slutanvändarbeteende; grön byggnad; VVS-systemkontroll; värmepump; IDA ICE; smart nät; termisk komfort; termisk tröghet;

    Sammanfattning : Sweden is undergoing energy transition to become a zero-carbon economy with electricity production aims at 100% from renewable resources by 2040. Sweden also has a national goal to have fossil-free vehicle fleet by 2030. The increasing share of intermittent renewable resources creates growth in mismatches between electricity supply and demand.
