  1. 1. Cosmological Horizons and the Unruh Effect

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Niklas Engelhardt Önne; [2023]
    Keywords : Unruh effect; quantum scalar fields; Bogoliubov transformations; accelerated observers; Minkowski spacetime; cosmological horizons; Rindler observers; special relativity; QFT; Unruh-effekten; skalära kvantfält; Bogoliubov-transformationer; accelererande referenssystem; Minkowski rumtid; kosmologiska horisonter; Rindlerobservatörer; speciell relativitetsteori; QFT;

    Abstract : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

  3. 2. Credit Index Forecasting: Stability of an Autoregressive Model

    University essay from KTH/Matematik (Avd.)

    Author : Melker Wallén; Erik Grimlund; [2023]
    Keywords : Credit spreads; Time Series; Credit Risk; Index Modeling; Forecasting; Kreditspreadar; Tidsserier; Kreditrisk; Indexmodellering; Prognoser;

    Abstract : This thesis investigates the robustness and stability of total return series for credit bond index investments. Dueto the challenges which arise for financial institutes and investors in achieving these objectives, we aim to createa forecasting model which matches the statistical properties of historical data, while remaining robust, stable andeasy to calibrate.

  4. 3. Design av hållbara parkeringar – material, växtval och ekosystemtjänster

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Jacob Persson; Martin Toft Möllerberg; [2023]
    Keywords : parkeringar; hållbarhet; uppbyggnad; uppbyggnad; växtval; urbana värmeöar; transformation; permeabelt; ekosystemtjänster; dagvattenhantering; BGG-system; upplevelsevärden;

    Abstract : Under vår utbildning för att bli Landskapsarkitekter har vi identifierat förbättringspotential för parkeringar generellt. De har ofta döende vegetation, saknar permeabla ytor och har suboptimal utformning. READ MORE

  5. 4. Exploring Normalizing Flow Modifications for Improved Model Expressivity

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

    Author : Marcel Juschak; [2023]
    Keywords : Normalizing Flows; Motion Synthesis; Invertible Neural Networks; Glow; MoGlow; Maximum Likelihood Estimation; Generative models; normaliserande flöden; rörelsesyntes; inverterbara neurala nätverk; Glow; MoGlow; maximum likelihood-skattning generativa modeller;

    Abstract : Normalizing flows represent a class of generative models that exhibit a number of attractive properties, but do not always achieve state-of-the-art performance when it comes to perceived naturalness of generated samples. To improve the quality of generated samples, this thesis examines methods to enhance the expressivity of discrete-time normalizing flow models and thus their ability to capture different aspects of the data.

  6. 5. Exploratory Innovations and Exploitation of Knowledge after Large Scale Agile Transformation : A Case Study at an Energy Utility R&D Department

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

    Author : Firas Daraiseh; [2023]
    Keywords : Agile Manifesto; Agile Principles; Large Scale Agile Transformation; Innovation; Organizational Ambidexterity; Knowledge Transfer.; Agilt manifest; agila principer; stor skala agil transformation; innovation; organisatorisk ambidextri; kunskapsöverföring.;

    Abstract : Many organizations from and outside of the IT industry are trying to implement Agile in their ways of working via large scale transformations. The organizations feels the need to become Agile in order to increase their client satisfaction, deliver their product faster, and compete in the rapidly changing market. READ MORE
