  2. 16. Low-power design methodologies for embedded internet systems

    Author : Jens Eliasson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Embedded systems are resource-constrained special-purpose computers, capable of both sensing and controlling the environment they are placed in. An embedded system usually consists of both hardware and software. The hardware can be composed of sensors, actuators, processors, memory storage devices, communication peripherals, and power supplies. READ MORE

  4. 17. Scaling Indoor Positioning : improving accuracy and privacy of indoor positioning

    Author : Jimmy Engström; Jan A. Persson; Åse Jevinger; Carl Magnus Olsson; Gustaf Hendeby; Malmö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Our phones have many uses for positioning technologies, such as navigation, LocationBased Services (LBS), emergency positioning, fitness applications, and advertising. We trust our phones and wearables to be location-aware. READ MORE

  5. 18. On LFSR based Stream Ciphers - analysis and design

    Author : Patrik Ekdahl; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-shrinking generator; shrinking generator; E0; A5; sober; stream cipher; LFSR; snow; Informatics; systems theory; Informatik; systemteori;

    Abstract : Stream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. READ MORE

  6. 19. Low Power Wireless Technologies for IIoT : Analysis and enhancement of communication delay, reliability and scalability

    Author : Raúl Rondón; Mikael Gidlund; Fortunato Santucci; Mittuniversitetet; []
    Keywords : ;

    Abstract : In recent years, the implementation of wireless communication systems in industrial environments has significantly increased. As a result, new applications such as Industrial Internet-of-Things (IIoT) have arisen, reshaping the future of industrial automation. READ MORE

  7. 20. Fast-response rotating brushless exciters for improved stability of synchronous generators

    Author : Jonas Kristiansen Nøland; Urban Lundin; Oskar Wallmark; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronous generators; permanent magnet machines; excitation systems; power electronic interfaces; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The Norwegian Network Code FIKS from the Norwegian Transmission System Operator (TSO) Statnett, states that synchronous generators ≥ 25 MVA must have a static excitation system. It also includes requirements on the step time response and the available field winding ceiling voltage of the excitation system. READ MORE
