  1. 1. Mass-Singularity Structure of QED and Perturbative Quantum Gravity Scatterings

    University essay from Lunds universitet/Teoretisk partikelfysik

    Author : Santiago Londono Castillo; [2020]
    Keywords : perturbative quantum gravity; QED; mass singularities; collinear singularities; soft singularities; singularity cancellation; graviton; Physics and Astronomy;

    Abstract : In this thesis, the mass singularities occurring in the cross-section of electron scattering processes are investigated. Two types of scatterings are studied: Quantum Electrodynamics (QED) scatterings, and Perturbative Quantum Gravity (PQG) scatterings. READ MORE

  2. 2. Investigation of Cu and Zn interactions with ilmenite during waste incineration

    University essay from Chalmers tekniska högskola / Institutionen för kemi och kemiteknik

    Author : Elin Borgman; [2020]
    Keywords : FactSage; copper; zinc; major ash elements;

    Abstract : In 2018, approximately 2.01 billion tons of waste was generated in the world. By 2050, this number is expected to increase drastically to 3.40 billion tons of waste annually as lower income countries develop and the world population increases (Kaz, Yao, BhadaTata, & Van-Woerden, 2018).

  3. 3. Conformal field theory at large N

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Nadia Flodgren; [2019]
    Keywords : Conformal field theory; conformal bootstrap; large N; anti-de Sitter; anomalous dimension; AdS CFT correspondence;

    Abstract : The conformal bootstrap method is a non-perturbative method that uses the symmetry in a conformal field theory to constrain and solve for the observables in the theory. We consider a conformal field theory with the symmetry group SU(N) and four general scalar fields as the only low dimensional operators. READ MORE

  4. 4. A Model of Universal Manual Design for Technical Products

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

    Author : Nuo Chen; [2019]
    Keywords : User manuals; universal design; accessibility; usability; modelling; mobile application; Manual; bruksanvisning; universell design; tillgänglighet; använderbarhet; modellering; mobilapplikation;

    Abstract : Unlike consumer technologies and electronics that have advanced and become more affordable and intuitive to use, the supplied user manuals are still using the old-fashioned book-like design. There are people who do not read the manuals, even when they are in trouble, because these book-like manuals might be too complicated or difficult to understand. READ MORE

  5. 5. Organizational dynamics : An investigation into a company's work culture and internal structures, to understand how it functions.

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Martin Vestberg; [2018]
    Keywords : Small to medium enterprices; iterative processes; culture; resistance; influence; group configurations; knowledge transfer; process perspective; social network analysis;

    Abstract : Background: Freno AB in Piteå has expanded rapidly in recent years and wishes to continue the expansion at aneven faster pace. At the same time, the company has noted that there are challenges to maintain high quality, goodeconomy and good marketability. READ MORE
