  1. 1. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity

    University essay from KTH/Fysik

    Author : Atabak Fathe Jalali; [2024]
    Keywords : Theoretical physics; astrophysics; modified gravity; minimally modified gravity; gravitational collapse; VCDM; scalar collapse; apparent horizon; numerical relativity; Teoretisk fysik; astrofysik; modifierad gravitation; minimalt modifierad gravitation; gravitationskollaps; VCDM; skalär kollaps; uppenbar horisont; numerisk relativitet;

    Abstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE

  3. 2. Fracture simulation with a hyperelastic phase field model

    University essay from KTH/Hållfasthetslära

    Author : Adrien Fradet; [2023]
    Keywords : Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Abstract : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

  4. 3. Cultural Sustainability : Influence of Traditional craft on Contemporary craft cross-culturally

    University essay from Konstfack/Textil

    Author : Bhumika Sethi; [2023]
    Keywords : Culture; Tradition; Regional craft; Circulation; Hand-made; Sustainability; Perspective;

    Abstract : Among the four dimensions of sustainability (environmental, economic, social, and cultural), it is the latter aspect that is least examined. However, understanding how culture contributes to the long-term sustainability of communities and societies is one key to a holistic understanding of sustainability itself, and further how it can impact the textile in different cultures.

  5. 4. Design of a Blockchain-Based P2P Energy Marketplace within a Single Energy Retailer Framework

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

    Author : Adrian Brasero Romo; [2023]
    Keywords : Blockchain; Energy Marketplace; Prosumer; Sustainability; Renewable Energy; Surplus of energy; Decentralized Trading; Economic Viability.; Blockchain; Energimarknad; Prosumer; Hållbarhet; Förnybar Energi; Energiöverskott; Decentraliserad Handel; Ekonomisk Livskraft.;

    Abstract : In the era of rapid technological innovation, the convergence of blockchain technology and energy management has garnered significant attention. The escalating numbers of prosumers—individuals both producing and consuming energy—indicate a shift in the energy paradigm, demanding new frameworks for energy exchange. READ MORE

  6. 5. "It matters what stories we tell to tell other stories with" : A Feminist-Phenomenological Re-telling of Donna Haraway's Practices of Collaborative Writing and Storytelling

    University essay from Stockholms universitet/Institutionen för kultur och estetik

    Author : Silvia Thomackenstein; [2023]
    Keywords : Feminist writing; phenomenology; Donna Haraway; Situated Knowledges; storytelling; nomadic subjects; co-authoring; Rosi Braidotti; Nina Lykke; Mona Livholts; feminist modes of academic writing; curatorial editing; publishing; exhibition catalogue; worlding; becoming-with; curatorial research; quoting; referencing; Carolyn Christov-Bakargiev; Bruno Latour; Peter Weibel; transdisciplinarity;

    Abstract : This paper explores through Donna Haraway's storytelling practices feminist approaches to collaborative writing. Employing a phenomenological qualitative research approach, the thesis aims to analyze how Haraway herself exercises feminist writing and facilitates the learning of collaborative storytelling.
