  1. 1. 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

  2. 2. Capturing Tail Risk in a Risk Budgeting Model

    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Filip Lundin; Markus Wahlgren; [2020]
    Keywords : ;

    Abstract : Risk budgeting, in contrast to conventional portfolio management strategies, is all about distributing the risk between holdings in a portfolio. The risk in risk budgeting is traditionally measured in terms of volatility and a Gaussian distribution is commonly utilized for modeling return data. READ MORE

    Abstract : The automotive industry is undertaking major technological steps in an effort to reduce emissions and fight climate change. To reduce the reliability on fossil fuels a lot of research is invested into electric motors (EM) and their applications. READ MORE

  4. 4. Tick data clustering analysis establishing support and resistance levels of the EUR-USD exchange market

    University essay from Lunds universitet/Matematisk statistik

    Author : Karl Tengelin; [2020]
    Keywords : Tick data; Support-and resistance levels; Clustering methods; Gaussian mixture model; Kmeans; EUR-USD exchange rates; Clustering performance metrics; Market activity; Mathematics and Statistics;

    Abstract : Our aim is to use clustering algorithms in order to compute support and resistance levels within an intra-day trading setting. To achieve this we use a tick data set from the EUR-USD exchange market during 2019 as a measure of market activity. READ MORE

  5. 5. Improved Sensor Planning in Binaural Probabilistic Active SoundLocalisation for Robots

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Arvid Norlander; [2020]
    Keywords : ;

    Abstract : Sensor planning in the field of active robot sound localisation is an important topic that has potential applications for robots interacting with crowds, search and rescue and more, though the field is currently at the level of basic research. This thesis presents novel improvements that theoretically increase the accuracy of the predictions used in probabilistic sensor planning for sound localisation. READ MORE
