  1. 1. Control Aid Implementation -Modelling and simulation of triple extruder-

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Karl Langsér; [2023]
    Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE

  3. 2. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Shakhera Akter Shimu; [2023]
    Keywords : Climate change; plant phenology; phenological traits; phenology change; cumulative temperature; phenotypic plasticity; genotypic variation;

    Abstract : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. READ MORE

  4. 3. Agile robotic arm for vertical applications - Evaluation, design and development

    University essay from Lunds universitet/Maskinelement

    Author : Rasmus Gren; [2023]
    Keywords : Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

    Abstract : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. READ MORE

  5. 4. Real time control of an active pendulum arm suspension system for a downscaled XT28 forwarder model

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Niclas Määttä; Adam Westermark; [2023]
    Keywords : mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Abstract : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. READ MORE

  6. 5. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Henrik Johansson; Martin Heinegård; [2020]
    Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE
