  1. 11. A sensor orientation and signal preprocessing study of a personal fall detection algorithm

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Viktor Johansson; [2020]
    Keywords : Decision tree; fall detection algorithm; machine learning; smartphone; accelerometer; gyroscope; low-pass filter;

    Abstract : This study investigates if a smartphones orientation in the pocket affects the result of a decision tree model trained with data from personal falls, and also how a low-pass filter affects these results. A comparison is made between the results gathered from this study, compared to previous studies and products within the field. READ MORE

  3. 12. Filter Design for an HVDC protection IED

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

    Author : Evgeny Genov; [2020]
    Keywords : ;

    Abstract : A selective fault detection approach is necessary for successful implementation of multi-terminal high-voltage direct-current (HVDC) grids. Fault detection is per- formed by an intelligent electronic device (IED) that takes in voltage and current measurements, performs fault detection algorithms, and outputs, e.g. READ MORE

  4. 13. Bi-directional Low Pass Filter and Mixer Design

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

    Author : Sharath Thandava Murthy; Meshach Milon Paul Pear Pradeep Kumar; [2020]
    Keywords : Technology and Engineering;

    Abstract : This report presents the research and implementation of a bidirectional filter and mixer combination for the transceiver chain in 5G TDD equipment. The main objective of this project is to find a feasible design for mixer and low pass filter to reuse the same hardware blocks for both transmitter and receiver chain. READ MORE

  5. 14. Thermographic Measurements of Hot Materials Using a Low- to High-speed RGB-camera : Prospect of RGB-cameras Within the Field of Thermographic Measurements

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Therese Berndtsson; [2019]
    Keywords : RGB-camera; thermographic measurements; calibration; temperature transform; thermal behavior; dual-wavelenght;

    Abstract : Monitoring the thermal behavior of material while heated or cooled is of great importance in order to understand the structural behavior of materials. This thesis aims to investigate the prospects for imaging hot materials using an RGB-camera. READ MORE

  6. 15. 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
