  1. 1. Comparing decentralized learning to Federated Learning when training Deep Neural Networks under churn

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

    Author : Johan Vikström; [2021]
    Keywords : Peer- to- Peer; Decentralized Machine Learning; Federated Learning; Gossip Learning; Long Short- Term Memory; Convolutional Neural Network; Peer- to- peer; Decentraliserad Maskininlärning; Federated learning; Gossip learning; Lång korttidsminne;

    Abstract : Decentralized Machine Learning could address some problematic facets with Federated Learning. There is no central server acting as an arbiter of whom or what may benefit from Machine Learning models created by the vast amount of data becoming available in recent years. READ MORE

  2. 2. The Performance of Post-Quantum Key Encapsulation Mechanisms : A Study on Consumer, Cloud and Mainframe Hardware

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Alex Gustafsson; Carl Stensson; [2021]
    Keywords : Public-Key Cryptography; Benchmark; x86; IBM Z; z15; Asymmetrisk Kryptering; Prestandatest; x86; IBM Z; z15;

    Abstract : Background. People use the Internet for communication, work, online banking and more. Public-key cryptography enables this use to be secure by providing confidentiality and trust online. Though these algorithms may be secure from attacks from classical computers, future quantum computers may break them using Shor’s algorithm. READ MORE

  3. 3. Reflection Seismic Survey for Characterising Historical Tailings and Deep Targeting at the Blötberget Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : EMMANUEL ALOFE; [2021]
    Keywords : reflection seismic; exploration; tailings; sustainability; circularity; tomography; reflektion seismisk; prospektering; gruvavfall; hållbarhet; cirkularitet; tomografi;

    Abstract : Iron has been an essential element to human development and iron-oxide deposits are known to host minerals that are labelled as critical raw materials (CRMs), especially in the EU. Therefore, ensuring a sustainable supply of CRMs require access to both primary and secondary sources of their host deposits such as iron oxides. READ MORE

  4. 4. State- and Parameter Estimation for Spacecraft with Flexible Appendages using Unscented Kalman Filters

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Andrea Mosquera Alonso; [2019]
    Keywords : Estimation; flexibility; flexible spacecraft; spacecraft; kalman filter; unscented Kalman filter; spacecraft dynamics; flexible dynamics;

    Abstract : The problem of system identification for dynamic effects on spacecraft has become increasingly relevant with the surge of agile spacecraft, which must perform large amplitude maneuvers at high rates. Precise knowledge of the state of the spacecraft, as well as of the parameters characterizing its motion, is vital for the design of control algorithms enabling stabilization and pointing accuracy.

  5. 5. Hom-Lie algebras and deformations

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Germán García Butenegro; [2019]
    Keywords : Lie; Hom-Lie; quasi-Lie; derivations; Witt; Virasoro; central extensions.;

    Abstract : Document intends to re-establish Hom-Lie algebra theory for a wider class of morphisms on the underlying coefficient algebra. A look is taken into deformed Witt and Virasoro algebras and a new direction is taken into further quasi-Hom-Lie VIrasoro-type extensions for different Witt algebras. .. READ MORE
