  1. 1. BGPcredit : A Blockchain-based System for Securing BGP

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yu Yang Liu; [2022]
    Keywords : blockchain; RPKI; consensus algorithm; border gateway protocol; security; blockchain; RPKI; konsensusalgoritm; border gateway-protokoll; säkerhet;

    Abstract : Due to the absence of appropriate security mechanisms, even the latest version of Board Gateway Protocol (BGP) is still highly vulnerable to malicious routing hijacking. The original problem is that BGP allows router to accept any BGP update message without any extra validation process. READ MORE

    Abstract : Ankle exoskeletons are designed to help people with movement weakness to restore the walking ability . However, people with gait pathology, for instance, drop foot, usually have difficulties in lifting the front part of foot during gait. READ MORE

  5. 4. Competitiveness in Power System Frequency Regulation Markets : Competitive analysis of the FCR-D up regulation market in Sweden

    University essay from KTH/Energiteknik

    Author : Yu-Hsuan Li; [2021]
    Keywords : ;

    Abstract : The growing share of weather-dependent power generation in the Swedish power system is challenging the stability of the whole system. Therefore, the need to increase system flexibility by frequency regulation reserves is enlarged. Nowadays, the reserves are mainly supplied by Hydropower. READ MORE

  6. 5. Development and Testing of Performance Assessment Equipment for Elite Fencers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yu Ge; [2019]
    Keywords : ;

    Abstract : The main purpose of this thesis is to use a low-quality inertial sensor, whichonly provides 3-D acceleration and 3-D angular velocity, to have good poseestimation results, which is to track the orientation, the velocity and the displacementof some fencing relevant movements. This thesis focuses on twomain parts, algorithms for pose estimation and algorithms for re-calibration ofboth the accelerometer and the gyroscope. READ MORE
