  1. 21. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Hanna Marklund; [2019]
    Nyckelord :Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

    Sammanfattning : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. LÄS MER

  2. 22. Dynamic algorithm selection for machine learning on time series

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Love Dahlberg; [2019]
    Nyckelord :Computer science; Machine learning; Selection; time series; Algorithm selection;

    Sammanfattning : We present a software that can dynamically determine what machine learning algorithm is best to use in a certain situation given predefined traits. The produced software uses ideal conditions to exemplify how such a solution could function. LÄS MER

  3. 23. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    Magister-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Vidar Flodgren; [2019]
    Nyckelord :GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Sammanfattning : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. LÄS MER

  4. 24. Automatiserat beslutsfattande : Hur automatiseringen av offentlig sektor påverkar förmågan att efterfölja offentlighetsprincipens regelverk

    Master-uppsats, Uppsala universitet/Institutionen för ABM

    Författare :Lisa Fagerström; [2019]
    Nyckelord :The principle of public access to official records; Automated decision-making; Algorithms; Public sector; Posthumanism; Offentlighetsprincipen; automatiserat beslutsfattande; algoritmer; offentlig sektor; automatisering; allmän handling; posthumanism;

    Sammanfattning : The aim of this thesis is to gain knowledge of how automated decision-making in Swedish public authorities affects the ability to comply with the Swedish principle of public access to official records. This is done through a Posthumanist analysis of seven qualitative interviews. LÄS MER

  5. 25. Comparison study on graph sampling algorithms for interactive visualizations of large-scale networks

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

    Författare :Alexandra Voroshilova; [2019]
    Nyckelord :Graph sampling; graph filtering; large graph visualization; grafreduktion; stor graf visualisering;

    Sammanfattning : Networks are present in computer science, sociology, biology, and neuroscience as well as in applied fields such as transportation, communication, medical industries. The growing volumes of data collection are pushing scalability and performance requirements on graph algorithms, and at the same time, a need for a deeper understanding of these structures through visualization arises.
