  1. 6. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    University essay from KTH/Tillämpad fysik

    Author : Emrah Tortumlu; [2023]
    Keywords : Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Abstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  2. 7. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    University essay from KTH/Kemi

    Author : Arezu Sehati; [2023]
    Keywords : Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Abstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

  3. 8. EcoBot : study design and development of a persuasive FSM-free Chatbot for energy saving

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

    Author : Francesco Milano; [2023]
    Keywords : chatbot; context management; persuasive strategies; domestic energy saving; smart appliances; sustainability.; chatbot; kontexthantering; övertygande strategier; hushållsenergibesparing; smarta apparater; hållbarhet;

    Abstract : This study presents the development and evaluation of a conversational agent, EcoBot, designed to inform users about their energy habits and persuade them to save more energy when at home, to help fight climate change and energy waste. To reach this goal, three persuasion strategies were first identified: Feedback, to give users personalized suggestions based on their habits, Goal Setting, to set and track consumption goals for the user’s domestic appliances, and Social Comparison, to compare the user’s consumption with that of others.

  4. 9. Analysing the effects of 24/7 Carbon-free Energy procurement strategies on the electricity system : Case Study of commercial and industrial sector in the Netherlands

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : NINA JABŁOŃSKA; [2023]
    Keywords : 24 7 Carbon-free Energy; carbon accounting; corporate electricity procurement; Energy Attribute Certificates; hourly matching; the Netherlands.; 24 7 kolfri energi; koldioxidredovisning; företagens elupphandling; energiattributcertifikat; timmatchning; Nederländerna.;

    Abstract : Considering the growing importance of the electricity sector in the worldwide decarbonisation efforts, as well as large volumes of energy consumed by the commercial and industrial (C&I) sector, corporate power procurement is found to be a significant contributor to building a net zero economy. Within this topic, hourly matching of carbon-free electricity supply with demand, or 24/7 Carbon-free Energy (24/7 CFE), is identified as a next-generation power procurement framework, with growing interest from a wide range of stakeholders in the energy sector and benefits backed by robust research evidence.

  5. 10. Data Centres as Prosumers: A Techno-Economic Analysis

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Jeremy Ericsson Sintong; [2023]
    Keywords : Data Centres; Prosumers; Techno-Economic Analysis; Waste Heat Recovery; District Heating; Heat Supply; Air-Cooled Data Centre;

    Abstract : Rapid growth of digitalization has urged Data Centres (DC) to be more energy efficient by recovering waste heat from server racks that would otherwise be wasted. This techno-economic study is focused on upgrading low temperature waste heat from typical Air-Cooled DC for District Heating Network (DHN) market in Stockholm region. READ MORE
