  1. 1. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

    University essay from KTH/Kemiteknik

    Author : Josefin Strandberg; [2023]
    Keywords : Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

    Abstract : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. READ MORE

  3. 2. Effect of climate exposure on mechanical performance of uncured ahdesive joints

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Rosa Sala Piñol; [2022]
    Keywords : Adhesives; uncured; adhesive joints; automotive; epoxy;

    Abstract : Adhesive bonding has become an essential joining method in the automotive industry specially with the recent focus on lightweight reduction. A major limiting factor to the widespread implementation of this joining method is concerns about environmental durability. READ MORE

  4. 3. Robust control system development forVTOL-to-fixed wing flight transition withthe EcoSoar UAV : A masters thesis in Automatic Control

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Robert Hedman; [2020]
    Keywords : drone; UAV; thesis; automatic; control; VTOL;

    Abstract : A non switching, non linear, quaternion based attitude P2 controller, together with a sensitivitynormalizing function for the control surfaces has been simulated and implemented on a flying fixedwing with non vectored engines. In simulations the controller worked well in all flight modes,hovering, transition and flying, and also rejected a simple wind disturbance in all modes. READ MORE

  5. 4. Learning Models of Communication Protocols using Abstraction Techniques

    University essay from Institutionen för informationsteknologi

    Author : Johan Uijen; [2009]
    Keywords : ;

    Abstract : In order to accelerate the usage of model based verification in real life software life cycles, an approach is introduced in this thesis to learn models from black box software modules. These models can be used to perform model based testing on. In this thesis models of communication protocols are considered. READ MORE
