  1. 21. Cyclotomic Fields and Fermat's Last Theorem

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Samuel Runyeon Odeberg; [2021]
    Keywords : pure mathematics; number theory; algebra; algebraic number theory; cyclotomic fields; cyclotomic rings; cycltomic integers; Fermat s last theorem; Mathematics and Statistics;

    Abstract : Number theory is in a sense among the oldest disciplines of mathematics. A running theme is that many number theoretic problems are very easy to state and understand. However, actually solving these problems often requires much work or some very clever trick. READ MORE

  3. 22. F-theory on six-dimensional symmetric toroidal orbifolds

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Finn Bjarne Kohl; [2021]
    Keywords : F-theory; orbifolds; String Theory; String Phenomenology; roto-translations; six-dimensional; F-Theorie; Orbifaltigkeiten; String Theorie; String Phenomenologie; Roto-Translationen; sechs-dimensional;

    Abstract : In this thesis, compactifications of F-theory on six dimensional symmetric toroidalorbifolds are explored. These orbifold geometries have been mathematically classified and it is natural to ask what the physical implications of string theorycompactifications on those geometries are. READ MORE

  4. 23. Estimating the end-to-end runtime with a dynamically built graph with exponentially moving average on serverless applications

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Jagiello Jakub; [2021]
    Keywords : ;

    Abstract : Function-as-a-Service (FaaS) is a technology for developing serverless applications scaled and managed entirely by the Cloud provider. Applications are composed of functions that are connected in a graph-like fashion to solve complex problems. READ MORE

  5. 24. Computational and accuracy benchmarking of simulation and system-theoretic models for production systems engineering

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Antonio José Ramos Calderón; [2021]
    Keywords : DES; benchmarking; lean buffer; optimization; simulation software; performance measure; plant simulation; FACTS; PSE toolbox;

    Abstract : The modern industry has an increasing demand for simulation software able to help workers and decision-makers visualize the outputs of a specific process in a fast, accurate way. In this report, a comparative study between FACTS (Factory Analyses in ConcepTual phase using Simulation), Plant Simulation, and PSE (Production System Engineering) Toolbox is done regarding their capacity to simulate models with increasing complexity, how accurate they are in their outputs with different optimized buffer allocations, and how well they perform on the task of detecting the bottlenecks of a process.

  6. 25. Periodical Maintenance Modelling and Optimisation Assuming Imperfect Preventive Maintenance and Perfect Corrective Maintenance

    University essay from KTH/Optimeringslära och systemteori

    Author : Madeleine Engvall Birr; Lisette Lansryd; [2021]
    Keywords : Master Thesis; Maintenance Management; Maintenance Modelling; Imperfect PM; Perfect CM; Periodic Policy; Genetic Algorithms; Age Reduction; Masterexamensarbete; Underhållsarbete; Underhållsmodellering; Ofullständiga FU; Perfekta AU; Periodisk Planläggning; Genetiska Algoritmer; Åldersreduktion;

    Abstract : In this paper, a periodic maintenance model is formulated assumingcontinuous monitoring, imperfect preventive maintenance (PM) and perfect correctivemaintenance (CM) using three decision variables, (I, N, Z). The model is derived in aninfinite horizon context where the mean cost per unit time is modelled. READ MORE
