  • Progress has been made in individual functionalities, but the overall grade continues to be at an adequate level. Usability focused questionnaires conducted in 2014 and 2010 are a part of the first national eHealth monitoring study on the usability and user experiences of electronic health record systems. In total, over 3 000 physicians actively doing clinical work responded to both questionnaires. 'There has been no improvement in the overall experience in four years even though the usability...
  • Pereida Garcia and co-authors discovered attacks against widely used cryptographic libraries. Cesar Pereida Garcia was the winner of this year's FISA national thesis competition in the master's thesis series with his thesis "Cache-Timing Techniques: Exploiting the DSA Algorithm". In his thesis, Pereida Garcia reported how they can attack widely used software to learn secret keys used by victims. He also showed how to fix the vulnerabilities that made the attacks possible. "Last month Pereida...
  • Honours programme student Preethi Lahoti conducts research in graph mining and social-networks analysis. Exceptionally qualified Master’s students have joined the honours programme in computer science. Altogether 15 Master’s students from all over the world will have hands-on experience in the actual computer science research. Majority of the honours programme students are specialized in the machine learning, data mining and probabilistic modelling research area. Preethi Lahoti...
  • The study utilises model checking to address the insufficiencies of testing and simulation in the verification of safety systems. The object of Jussi Lahtinen’s dissertation was to find a more formal and mathematical approach to system verification and to develop model checking practices that are suitable for the nuclear industry. The traditional system verification methods, such as testing and simulation, do not have enough coverage to address the increasing digitalisation of safety...
  • Research data was collected from Kenyan national parks over the past 60 years, combined with traits of the teeth of herbivorous mammals. In the new study, the annual rainfall and average temperatures in the national parks are inferred from the teeth of herbivorous mammals. Such reverse engineering opens up new opportunities for interpreting fossil records. The results were recently published in the journal PNAS. Exact data on the number and geographical spread of the animals in Kenya’s...
  • Ojala challenged young researchers and students to in-depth scientific thinking while remaining there to support them. Professor of Digital Technology Leo Ojala passed away recently at the age of 80. He retired from his professor’s duties in 2000, having been one of the first professors of computer science in Finland. Ojala graduated from the Department of Physics of Helsinki University of Technology in 1960. He worked in industry for some years and then moved back to the Department of...

  • Majority of the honours programme students are specialized in the machine learning, data mining and probabilistic modelling research area. Students admitted to the honours programme are associated to one of the Department of Computer Science research groups, and have the opportunity for part-time employment during semesters in research-related work. Alexandru Mara from Spain, originally from Romania, is studying massive datasets with an intrinsic network structure, such as the Amazon product...
