    University essay from Umeå universitet/Institutionen för fysik

    Author : Fanny Bleckur; [2023]
    Keywords : ;

    Abstract : Northvolt is committed to developing the world’s greenest battery. To achieve this,energy-efficient production processes are essential and dehumidification is a crucial, yet energy-intensive, process for battery production. READ MORE

  2. 2. Sensorless Field-Oriented Control and Position Estimation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Roberts Bitenieks; Lars Brander; [2023]
    Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE

  3. 3. The OpenXO. 3D Printed Modular Exoskeleton Segment

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Árni Þór Þorgerirsson; [2023]
    Keywords : Exoskeleton; Open-Source; Fused Filament Fabrication FFF ; Cycloidal Drive; OpenXO; precision fabrication;

    Abstract : Exoskeletons are wearable devices that enhance or supplement the user’s natural abilities. They have been demonstrated to be efective in alleviating pain, reducing work related injuries, improving working conditions, and can play a pivotal role in improving recovery times and recovery outcomes.

  4. 4. Modeling of the trajectory of ice thrown from a wind turbine

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Elena Rocchi; [2023]
    Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

    Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

  5. 5. DRONAR: Obstacle echolocation using ego-noise

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Henrik Nilsson; [2023]
    Keywords : Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

    Abstract : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. READ MORE
