  1. 16. Electromagnetic analysis of AES-256 on Xilinx Artix-7

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Oskar Westman; [2018]
    Keywords : Electromagnetic side-channel attack; AES-256; Artix-7; FPGA; Differential analysis; Simple analysis.; Technology and Engineering;

    Abstract : In this project, an electromagnetic side-channel attack has been made by exploiting the information leakage from a field programmable gate array (FPGA) and an implemented advanced encryption standard with a 256-bit key (AES-256). The FPGA-board was a Nexys-4 from Digilent with Artix-7 FPGA. The attack was partially successful. READ MORE

  3. 17. Cell Acquisition and Synchronization for Unlicensed NB-IoT

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Eskil Jörgensen; [2017]
    Keywords : Narrowband Internet-of-Things; NB-IoT; unlicensed; cell search; cell acquisition; synchronization; artificial fast fading; binary sequences; peak sidelobe level;

    Abstract : Narrowband Internet-of-Things (NB-IoT) is a new wireless technology designed to support cellular networks with wide coverage for a massive number of very cheap low power user devices. Studies have been initiated for deployment of NB-IoT in unlicensed frequency bands, some of which demand the use of a frequency-hopping scheme with a short channel dwell time. READ MORE

  4. 18. Forecasting Trajectory Data : A study by Experimentation

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Shiva Sai Sri Harsha Vardhan Kamisetty Jananni Narasimha; [2017]
    Keywords : Collapsed weighted tensor method; periodic temporal link prediction; Trajectory data.;

    Abstract : Context. The advances in location-acquisition and mobile computing techniques have generated massive spatial trajectory data. Such spatial trajectory data accumulated by telecommunication operators is huge, analyzing the data with a right tool or method can uncover patterns and connections which can be used for improving telecom services.

  5. 19. Simultaneous detection of potassium, water vapor and temperature with tunable diode laser absorption spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Edvin Norén; [2015]
    Keywords : TDLAS; DAS; WMS; Simultaneous detection; Measurement; Potassium; Water vapor; Temperature; Biomass; Optics;

    Abstract : Existing tunable diode laser absorption spectroscopy (TDLAS) sensors for potassium (K) and for water vapor (H2O) and temperature were combined to enable simultaneous measurements in combustion and gasification processes. In-situ real-time detection of the above mentioned combustion parameters will improve the understanding of ash-formation during thermochemical conversion of biomass. READ MORE

  6. 20. Low Energy GPS Positioning : A device-server approach

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Martin Szilassy; Daniel Örn; [2015]
    Keywords : GPS; low energy consumption; positioning; localization; tracking; GNSS; coarse time navigation; CTN; Doppler navigation; acquisition; internet of things; signal processing; max2769;

    Abstract : GPS is widely used for localization and tracking, however traditional GPS receivers consume too much energy for many applications. This thesis implements and evaluates the performance of a low energy GPS solution, including a working hardware prototype, that reduces energy consumption significantly. READ MORE
