Stream ciphers are cryptographic primitives that ensure the confidentiality of communications. In this thesis, we study several attacks on stream ciphers. For practical applications, the candidates of stream ciphers of NESSIE and eSTREAM projects are scrutinized. Firstly, the algebraic attacks on SOBER-t32 and SOBER-t16 stream ciphers are performed under the assumption that the stuttering phase...

Previous research has demonstrated that adults with attention deficit/hyperactivity disorder (ADHD) are more likely to experience driving-related problems, which suggests that they may exhibit poorer driving performance. However, direct experimental evidence of this hypothesis is limited. The current study involved 2 experiments that evaluated driving performance in adults with ADHD in terms of...

The effects of ingesting ethanol have been shown to be somewhat variable in humans; there appear to be but few universals. Yet, questions about intoxication often are asked by law enforcement personnel (especially relative to DUI), clinicians and various individuals in social settings. A key question: Is it possible to determine if a person is intoxicated by observing them in some manner? A clo...


 The paper presents three different projections of the future number Sámi language users in Norway based on contemporary children receiving instruction Norwegian school system, either North, Lule or South Sámi. There exist curricula for subject Sámi, one first pupils (Sámi 1), second 2), and with no previous knowledge 3). Depending whether only 1 become users, also 2 even 3 do so, a sober...
