  1. 16. Keystroke dynamics for student authentication in online examinations

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

    Author : Rebecka Mattsson; [2020]
    Keywords : ;

    Abstract : Biometrics are distinctive for each person, and can not be given away or hacked like a password. Keystroke dynamics is a behavioral biometric characteristic that can be used as a complementary authentication step [1]. In online examinations it is difficult to make sure that each student write their own work. READ MORE

  3. 17. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE

  4. 18. Adversarial Attacks against Behavioral-based Continuous Authentication

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

    Author : Maciej Kufel; [2020]
    Keywords : ;

    Abstract : Online identity theft and session hijacking attacks have become a major hazardin recent years and are expected to become more frequent in the years to come.Unlike the traditional authentication methods, continuous authentication based onthe characterization of user behavior in interactions with the computer system allowsto continuously verify the user’s identity and mitigates the risk of such forms ofmalicious access.

  5. 19. Nutrient dynamics in pak choi cultivation fertilized with biogas digestate : effects of non-nutrient digestate elements and amendment with mineral nutrients

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Kristina Weimers; [2020]
    Keywords : Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

    Abstract : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. READ MORE

  6. 20. Motion of a Gaussian Through a 2D Dilute BEC Droplet

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Zhanna Kuhrij; [2020]
    Keywords : Bose-Einstein Condensate; BEC; Droplet; Dilute; Liquid; Quantum Mechanics; Fluid Dynamics; Superfluid; Superfluidity; Quantum Fluctuations; LHY-correction; Flow patterns; Gaussian; 2D; Vortices; Gross-Pitaevskii Equation; Physics and Astronomy;

    Abstract : In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. READ MORE
