  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    University essay from Uppsala universitet/Materialteori

    Author : Viktor Frilén; [2023]
    Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Abstract : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  3. 2. Evaluation of a computational method for natural fiber-reinforced plastics

    University essay from KTH/Hållfasthetslära

    Author : Anna Lim; [2023]
    Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

  4. 3. Minimum Cost Distributed Computing using Sparse Matrix Factorization

    University essay from KTH/Optimeringslära och systemteori

    Author : Seif Hussein; [2023]
    Keywords : Applied mathematics; optimization; convex optimization; matrix factorization; sparse matrix factorization; distributed computing; linearly separable distributed computing; ADMM; alternating direction method of multipliers; tillämpad matematik; optimering; konvex optimering; matrisfaktorisering; gles matrisfaktorisering; distribuerade beräkningar; admm; alternating direction method of multipliers;

    Abstract : Distributed computing is an approach where computationally heavy problems are broken down into more manageable sub-tasks, which can then be distributed across a number of different computers or servers, allowing for increased efficiency through parallelization. This thesis explores an established distributed computing setting, in which the computationally heavy task involves a number of users requesting a linearly separable function to be computed across several servers.

  5. 4. The road towards achieving an improved aftermarket spare parts management : A case study at company X

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sabrina Medhanie Andemicael; Julia Ay; [2023]
    Keywords : Aftermarket business; Service level; Demand patterns; Spare parts management; Safety stock management;

    Abstract : Purpose: The purpose of this study was to analyze possible strategies that can be used to improve the efficiency of the spare parts safety stock management in a multinational company which operates in the electronic industry. Research question: “Which safety stock dimensioning strategies are most suitable in an after-sales business environment, characterized by high level customer service and unpredictable demand?” Method: The theoretical framework illuminated the study’s phenomenon which was mainly based on peer-reviewed scientific articles but also academic books.
