  1. 1. vehicleLang: a probabilistic modeling and simulation language for vehicular cyber attacks

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

    Author : Sotirios Katsikeas; [2018]
    Keywords : Domain Specific Language; Probabilistic Modeling; Cyber Security; Threat Modeling; Attack Graphs; Vehicular Security; Domänspecifikt språk; Probabilistisk modellering; Cybersäkerhet; Hotmodellering; Attackgrafer; Fordonsäkerhet;

    Abstract : The technological advancements in the automotive industry as well as in thefield of communication technologies done the last years have transformed thevehicles to complex machines that include not only electrical and mechanicalcomponents but also a great number of electronic components. Furthermore,modern vehicles are now connected to the Wide Area Network (WAN) and inthe near future communications will also be present between the cars (Vehicleto-Vehicle, V2V) and between cars and infrastructure (Vehicle-to-Infrastructure, V2I), something that can be found as Internet of Vehicles (IoV)in the literature.

  2. 2. Directly Cooled Windings - Conjugate heat transfer assessment of air-cooled hollow conductor

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Michael Gabassi; [2018]
    Keywords : Conjugate heat transfer; hollow conductor; thermal management; direct cooled windings; heat transfer; electrical machines; Technology and Engineering;

    Abstract : The torque capabilities of electrical machines are today limited by magnetic saturation and the ability to transfer thermal loads away from the machine. A solution to thermal management in power turbo-generators involves hollow conductors allowing direct cooling of the heat source thus increasing the power density significantly. READ MORE

  3. 3. Classification of incorrectly picked components using Convolutional Neural Networks

    University essay from KTH/Robotik, perception och lärande, RPL

    Author : Eric Kolibacz; [2018]
    Keywords : Convolutional Neural Network; Machine Learning; Neural Network; Pick and place machine; Assembly line;

    Abstract : Printed circuit boards used in most ordinary electrical devices are usually equipped through an assembly line. Pick and place machines as part of those lines require accurate detection of incorrectly picked components, and this is commonly performed via image analysis. READ MORE

  4. 4. Power Quality Analysis at Falu Hospital

    University essay from

    Author : Jennie Aldenlid; [2018]
    Keywords : ;

    Abstract : This is a master thesis performed on behalf of ABB Power Quality Center, aiming to investigate the power quality at Falu hospital. Hospitals can suffer from bad power quality both in the aspect of malfunctioning equipment, and as they can provide disturbances to the power grid. READ MORE

  5. 5. Comparison between active and passive rectification for different types of permanent magnet synchronous machines

    University essay from Uppsala universitet/Elektricitetslära

    Author : Johannes Örnkloo; [2018]
    Keywords : PMSG; PMSM; rectification; saliency; converter; wind power;

    Abstract : When using an intermittent source of energy such as wind power together with a synchronous machine a frequency converter system is needed to decouple the generator from the grid, due to the fluctuations in wind speed resulting in fluctuating electrical frequency. The aim of this master's thesis is to investigate how different types of rectification methods affect permanent magnet synchronous machines of different saliency ratios. READ MORE
