  1. 1. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

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

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

    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

  4. 3. A final drive device for torque vectoring in small racing cars

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sven Kalkan; [2023]
    Keywords : Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Abstract : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.

  5. 4. Development and analysis of fire suppresion during steel quenching : Three paths of analysis of fire- and smoke suppresion during steel hardening processes

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Alex Eidersjö; [2023]
    Keywords : Product development; Produktutveckling;

    Abstract : This thesis looks at an issue of excessive fire and smoke development during open tank quenching. The quenching in question being done as part of a hardening process of steel springs during manufacturing at Lesjöfors Fjädrar AB. The thesis was written under supervision of of Rejlers Sweden AB.

  6. 5. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Henriette Nishimwe; [2023]
    Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE
