  1. 1. Analysis and time calculations of NC files : Time calculation of Nailing Bridge machine movements

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Julia Rohnér; Emelie Sköld; [2023]
    Nyckelord :CNC-Machines; NC files; time calculations;

    Sammanfattning : Randek is a company that develops machines. The machines are used to build prefabricated houses. They have developed a CNC machine called Nailing Bridge that creates house walls. One of their issues is that they must predict the time it takes to build a wall because their customers need to know how long it takes to deliver their house. LÄS MER

  3. 2. Tether-free Driveline Control for Water Propulsion Devices

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi; Lunds universitet/Certec - Rehabiliteringsteknik och Design

    Författare :Isak Marklund; Axel Müller; [2023]
    Nyckelord :Dead man’s switch; electric surfboard; jet surfboard; machine learning; user experience; usability testing; neural network; decision tree; bootstrap aggregating; time series; Technology and Engineering;

    Sammanfattning : For many machines, safety requires the constant presence of an operator, with the risk of damage or danger if the operator is unintentionally absent. Dead man’s switches (DMS) are commonly used to halt operations if this absence is detected, often relying on physical elements like leashes or buttons. LÄS MER

  4. 3. ARCTIC PLANT COMMUNITIES RISE WITH TEMPERATURE Plant functional traits as a tool to predict global climate change

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Helena Sundell; [2022-07-06]
    Nyckelord :Arctic warming; plant functional traits; Community Weighted Mean; vegetational changes; global climate change;

    Sammanfattning : Global warming occurs at a rate at least three-fold in the arctic regions compared to the rest of the world. Here, plant community functional traits were assessed in response to experimental warming in three arctic areas of Fennoscandia (Latnajajure, Abisko and Kilpisjärvi). LÄS MER

  5. 4. Predictive Deceleration Control

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Felix Collin; [2022]
    Nyckelord :Predictive control; Map information; Feedforward control; Deceleration control; Prediktiv reglering; Information från kartor; Framkopplingsreglering; Retardationsreglering;

    Sammanfattning : For vehicles equipped with electric motors there exist a possibility to recuperate energy during deceleration. This master’s thesis presents a driver support function, a Predictive Deceleration Control (PDC), that warns the driver when to release the accelerator pedal. LÄS MER

  7. 5. Comparison of control strategies for Peltonturbines in Wave Energy Converters

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :PHILIP HAMILTON; ANDREAS SJÖGREN; [2021]
    Nyckelord :Permanent Magnet Synchronous Generator; Synchronous Motor; Wave Energy Converter; Pelton Turbine; Velocity Control Strategies; Dead-time Strategies; Cascaded Control; Permanentmagnetgenerator; Synkrongenerator; Synkronmotor; Vågenergiomvandlare; Peltonturbin; Hastighetskontrollstrategier; Mellantidsstrategier; Kaskadreglering;

    Sammanfattning : Wave energy is a promising renewable resource with a higher energy density than both wind and solar. Waves can travel thousands of kilometers with minimal energy loss, making them more reliable than the previously mentioned alternatives. A device that utilizes wave energy to generate electricity is calleda Wave Energy Converter. LÄS MER
