• User authentication based on keystroke dynamics analysis

  Publication

  • A. Kołakowska

  - Year 2011

  W pracy przedstawiono kilka metod, które można wykorzystać do uwierzytelniania użytkowników na podstawie rytmu pisania na klawiaturze. Dwie z opisanych metod wykorzystują miarę odległości zdefiniowaną do porównywania wpisywanych tekstów, natomiast trzecia analizuje parametry rozkładów cech wydobytych z wpisywanych tekstów. Algorytmy te zostały przetestowane na dwóch zbiorach danych. Ponadto oceniona została efektywność metody powstałej...

• Towards detecting programmers’ stress on the basis of keystroke dynamics

  Publication

  • A. Kołakowska

  - Annals of Computer Science and Information Systems - Year 2016

  The article describes the idea of detecting stress among programmers on the basis of keystroke dynamics. An experiment with a group of students of artificial intelligence classes was performed. Two samples of keystroke data were recorded for each case, the first while programming without stress, the second under time pressure. A number of timing and frequency parameters were calculated for each sample. Then statistical analysis...

• Keystroke Dynamics Patterns While Writing Positive and Negative Opinions

  Publication

  • A. Kołakowska
  • A. Landowska

  - SENSORS - Year 2021

  This paper deals with analysis of behavioural patterns in human–computer interaction. In the study, keystroke dynamics were analysed while participants were writing positive and negative opinions. A semi-experiment with 50 participants was performed. The participants were asked to recall the most negative and positive learning experiences (subject and teacher) and write an opinion about it. Keystroke dynamics were captured and...

• A review of emotion recognition methods based on keystroke dynamics and mouse movements

  Publication

  • A. Kołakowska

  - Year 2013

  The paper describes the approach based on using standard input devices, such as keyboard and mouse, as sources of data for the recognition of users’ emotional states. A number of systems applying this idea have been presented focusing on three categories of research problems, i.e. collecting and labeling training data, extracting features and training classifiers of emotions. Moreover the advantages and examples of combining standard...

• Targ Węglowy as the keystone of two ring road complexes of Gdańsk city centre

  Publication

  • Ł. Bugalski

  - Year 2014

  The urban structure of Gdansk city centre is determined by two ring road complexes. The first of them, the Gdansk Ring, has been created as a result of a city defortification at the turn of the 19th and 20th centuries and has been destroyed in the end of World War Two with the rest of Gdansk. The second, the Main Town Green Belt, has been formed in place of the medieval fortification system of the city’s most important historical...

  - PHYSICAL REVIEW A - Year 2002

  A model of discrete dynamics of entanglement of a bipartite quantum state is considered. It involves a global unitary dynamics of the system and periodic actions of local bistochastic or decaying channel. For initially pure states the decay of entanglement is accompanied by an increase of von Neumann entropy of the system. We observe and discuss revivals of entanglement due to unitary interaction of subsystems. For some mixed states...

  - INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE - Year 2023

  We discuss the dynamics of a relatively simple origami-inspired structure considering discrete and continuum models. The latter was derived as a certain limit of the discrete model. Here we analyze small in-plane deformations and related equations of infinitesimal motions. For both models, dispersion relations were derived and compared. The comparison of the dispersion relations showed that the continuum model can capture the behavior...

  - JOURNAL OF SOUND AND VIBRATION - Year 2015

  Single bubble sizing is usually performed by measuring the resonant bubble response using the Dual Frequency Ultrasound Method. However, in practice, the use of millisecond-duration chirp-like waves yields nonlinear distortions of the bubble oscillations. In comparison with the resonant curve obtained under harmonic excitation, it was observed that the bubble dynamic response shifted by up to 20 percent of the resonant frequency...
