    M1-uppsats, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Författare :Christoffer Jansson; Malte Pettersson; [2023]
    Nyckelord :State of Charge; Battery Management System; Nickel-metal hydride battery; Migration; Optimization; Execution time; C; CODESYS; LU Factorization; State of Charge; Battery Management System; Nickel-Metallhydridbatteri; Migrering; Optimering; Exekveringstid; C; CODESYS; LU-faktorisering;

    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. The Riemann Hypothesis and the Distribution of Primes

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :David Appelgren; Leo Tikkanen; [2023]
    Nyckelord :Riemann; Riemann Hypothesis; Zeta Function; Prime Number Theorem;

    Sammanfattning : The aim of this thesis is to examine the connection between the Riemannhypothesis and the distribution of prime numbers. We first derive theanalytic continuation of the zeta function and prove some of its propertiesusing a functional equation. LÄS MER

  5. 4. Recommending digital books to children : Acomparative study of different state-of-the-art recommendation system techniques

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

    Författare :Malvin Lundqvist; [2023]
    Nyckelord :Recommendation Systems; Collaborative Filtering; Matrix Factorization; Multi-Layer Perceptron; Neural Network-based Collaborative Filtering; Implicit Feedback; Deep Learning; Term Frequency-Inverse Document Frequency; Rekommendationssystem; Kollaborativ filtrering; Matrisfaktorisering; Flerlagersperceptron; Neurala nätverksbaserad kollaborativ filtrering; Implicit data; Djupinlärning; Termfrekvens med omvänd dokumentfrekvens;

    Sammanfattning : Collaborative filtering is a popular technique to use behavior data in the form of user’s interactions with, or ratings of, items in a system to provide personalized recommendations of items to the user. This study compares three different state-of-the-art Recommendation System models that implement this technique, Matrix Factorization, Multi-layer Perceptron and Neural Matrix Factorization, using behavior data from a digital book platform for children.

  7. 5. Sustainable Recipe Recommendation System: Evaluating the Performance of GPT Embeddings versus state-of-the-art systems

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Jaya Shankar Bandaru; Sai Keerthi Appili; [2023]
    Nyckelord :Sustainable Recipe Recommendation; Recommendation System; GPT-embeddings; PinSage; Factorization Machines;

    Sammanfattning : Background: The demand for a sustainable lifestyle is increasing due to the need to tackle rapid climate change. One-third of carbon emissions come from the food industry; reducing emissions from this industry is crucial when fighting climate change. LÄS MER
