  1. 1. XZDDF Bootstrapping in Fully Homomorphic Encryption

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Simon Ljungbeck; [2024]
    Nyckelord :Fully Homomorphic Encryption; Homomorphic Encryption; Bootstrapping; Blind Rotation; XZDDF; Technology and Engineering;

    Sammanfattning : Despite the vast research on the topic in recent years, fully homomorphic encryption schemes remain time-inefficient. The main bottleneck is the so-called bootstrapping, whose purpose is to reduce noise that has accumulated after having performed homomorphic operations on a ciphertext. LÄS MER

  3. 2. Bootstrapping Secure Sensor Networks in the Internet of Things

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Edman; [2022]
    Nyckelord :Internet of Things; Machine-to-machine communications; Internet security; Cryptographic protocols; Sakernas internet; Maskin-till-maskin kommunikation; Säkerhet på internet; Kryptografiska protokoll;

    Sammanfattning : The Internet of Things has become an integral part of modern society and continues to grow and evolve. The devices are expected to operate in various conditions and environments while securely transmitting sensor data and keeping low manufacturing costs. Security for the Internet of Things is still in its infancy and a serious concern. LÄS MER

  4. 3. Batch sizing in production : A case study on batch sizing at the press lines at Volvo GTO in Umeå

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Nyckelord :Analytics; Bootstrapping; Lean; Lean production; Logistics; Lot sizing; Manufacturing;

    Sammanfattning : Volvo GTO is currently interested in reducing their batch sizes at the press operation in Umeå. Where a large number of different cab parts are currently produced for trucks on two different production lines that interact with each other. LÄS MER

  5. 4. Presence detection by means of RF waveform classification

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Max Lengdell; [2022]
    Nyckelord :presence detection; machine learning; radio wave classification; unsupervised learning; supervised learning; sensor fusion; unsupervised classification;

    Sammanfattning : This master thesis investigates the possibility to automatically label and classify radio waves for presence detection, where the objective is to obtain information about the number of people in a room based on channel estimates. Labeling data for machine learning is time consuming and tedious process. To address this two approaches are evaluated. LÄS MER

  7. 5. Safe Reinforcement Learning for Remote Electrical Tilt Optimization

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Grigorios Iakovidis; [2021]
    Nyckelord :Remote Electrical Tilt; Antenna Tilt Optimization; Reinforcement Learning; SafeReinforcement Learning; Fjärrlutning; Antennlutningsoptimering; Förstärkningsinlärning; Säker Förstärkningsinlärning;

    Sammanfattning : The adjustment of the vertical tilt angle of Base Station (BS) antennas, also known as Remote Electrical Tilt (RET) optimization, is a simple and efficient method of optimizing modern telecommunications networks. Reinforcement Learning (RL) is a machine learning framework that can solve complex problems like RET optimization due to its capability to learn from experience and adapt to dynamic environments.
