  1. 1. AutoStore performance and the influence of context and configurations

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :David Flyrin; Daniel Lundkvist; [2023]
    Nyckelord :AutoStore; RCSRS; automated small-parts warehouse; goods-to-person picking; compact storage system; contextual factors; configurations; contingency theory; optimization; performance; Technology and Engineering;

    Sammanfattning : Problem description Multiple cases show that companies can improve performance after implementing an AutoStore system. However, research on optimizing the design and how to successfully control the AutoStore system is limited. LÄS MER

  3. 2. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator

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

    Författare :Simon Lundberg; [2022]
    Nyckelord :High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Sammanfattning : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. LÄS MER

  4. 3. Improving maintenance of CSS through structure and refactoring strategies

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Villiam Rydfalk; [2022]
    Nyckelord :CSS; Maintainability; Maintenance; Refactoring; Refactoring Strategies; Visual Regression; Dead Code; Refactoring Tools; CSS Structure;

    Sammanfattning : This study assesses how maintainability can be improved by manual and automatic refactoring strategies. Firstly, the structure of the CSS is important and CSS rules should conform to a certain order depending on their purpose. Secondly, dead code makes files unnecessarily large and more difficult to read. LÄS MER

  5. 4. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction

    Master-uppsats, KTH/Kemiteknik

    Författare :Caroline Kihlbom; [2021]
    Nyckelord :Solvent extraction; cobalt-nickel separation; CYANEX 272; pregnant leach solution; cobalt sulphate; Vätskevätskeextraktion; kobolt-nickel separation; CYANEX 272; laklösning; koboltsulfa;

    Sammanfattning : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Sammanfattning : 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. LÄS MER
