    Sammanfattning : Följande studie är utförd på uppdrag av företaget Nilar som tillverkar Nickel-Metallhydridbatterier (NiMH-batterier) vid sin produktionanläggning i Gävle. Den nuvarande beräkningen av State of Charge (SoC) sker på deras Battery Management Unit (BMU) och är implementerad i Structured Text i exekveringsmiljön CODESYS. LÄS MER

  3. 2. Discussion of Python Implementation Techniques for Discontinuous Galerkin Methods

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Ulf Vestberg; [2023]
    Nyckelord :Best approximation; Orthogonal polynomials; Legendre polynomials; Integration; Full tensor product; Sum-factorization; Dune; Mathematics and Statistics;

    Sammanfattning : This paper discusses implementation techniques for integration methods within the Discontinuous Galerkin Methods. These methods are used to approximate solutions for differential equations. To do so, one must compute a polynomial, which is an approximation of the used function. LÄS MER

  4. 3. Automated Functional Tests for a Web Application

    Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Johan Wulf; Erik Svensson Fahlström; [2022]
    Nyckelord :Test; automation; single sign on; frameworks; JavaScript; Technology and Engineering;

    Sammanfattning : When developing a large application, many companies use techniques such as Test Driven Development in order to get a range of tests on which they later can validate their code with. This has become the standard in many work environments. LÄS MER

  5. 4. Cyclotomic Fields and Fermat's Last Theorem

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

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

    Sammanfattning : 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. LÄS MER

  7. 5. Comparing Different Approaches for Solving Large Scale Power Flow Problems on the CPU and GPU with the Newton-Raphson Method

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Manolo D'Orto; [2020]
    Nyckelord :;

    Sammanfattning : Power system modelling is increasing in importance. It is vital for power system operations and transmission grid expansions, and therefore the future energy transition. The Swedish power system is under fast development to face the progress of more flexible demand, a higher share of distributed renewable sources, and updated capacities. LÄS MER
