  1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Erik Nordlund; [2023]
    Nyckelord :Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Sammanfattning : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. LÄS MER

  3. 2. Utveckling av ett fristående produktionsövervakningssystem

    Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Viktor Juhnke; [2023]
    Nyckelord :OEE; Industry 4.0; SCADA; SQL; Data visualization; PLC; HMI; Batch processing.; Technology and Engineering;

    Sammanfattning : In a global market with increasing competition, the need for efficient production increases. By measuring production parameters, a company can identify efficiency losses and thus prevent losses and create a more efficient production. Unknown and unplanned downtime in a production process leads to disruptions and losses in efficiency. LÄS MER

  4. 3. Flexible and modular production machines : A guiding framework and the design of a packaging machine

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Daniel Helmersson; [2023]
    Nyckelord :Logistics; flexibility; factories;

    Sammanfattning : To increase production and reduce intermediate storage in the factory a new flexible packaging machine is needed. The main purpose of this project is to design a new flexible and modular packaging machine and to create a new framework to use when designing new machines. LÄS MER

  5. 4. Risks and risk management in construction projects : A product life cycle approach

    Magister-uppsats, Högskolan i Gävle/Besluts-, risk- och policyanalys

    Författare :Björn Åberg; [2023]
    Nyckelord :Risk; Construction projects; Risk Management;

    Sammanfattning : The construction industry often operates with important and expensive projects that should meet deadlines and various regulations and at the same time avoid risks associated with the phases of the construction projects. This thesis reviews risks by a project life cycle (PLC) and the risk management used in construction projects by interviewing different construction project stakeholders such as hotel owners in Belgium and construction specialists.

  7. 5. Ligand-stimulated cleavage of PDGFR-beta

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Agni Karolina Tsiatsiou; [2023]
    Nyckelord :;

    Sammanfattning : Platelet-derived growth factor receptors (α and β) are included in the family of receptor tyrosine kinases (RTKs). The dimeric PDGF ligands bind to the PDGF receptors and this results in receptor dimerization, autophosphorylation, and thus activation. The autophosphorylated receptor dimer activates numerous signaling pathways. LÄS MER
