Until ca. 2000, information security was seen as a technological discipline, based on computer science but with mathematics helping in the design of ciphers and protocols. That perspective started to change as researchers and practitioners realized the importance of economics. As distributed systems are increasingly composed of machines that belong to principals with divergent interests, incent...

Based on the Kennaugh-Huynen decomposition, the Target Scattering Vector Model (TSVM) allows to extract four rollinvariant parameters. Those parameters are necessary for an unambiguous description of the target scattering mechanism. The proposed method consists in applying the TSVM prior to the GLRT-LQ detector for the detection of any oriented target.

We prove two cases of a strong version of Dejean’s conjecture involving extremal letter frequencies. The results are that there exist an infinite “ 5 4 + ” -free word over a 5 letter alphabet with letter frequency 1 6 and an infinite “ 6 5 + ” -free word over a 6 letter alphabet with letter frequency 1 5 . 1991 Mathematics Subject Classification. 68R15.

Dear Prof. Forastiere, Hereby we submit a revised version of our manuscript entitled: “Respiratory health effects of exposure to low levels of airborne endotoxin – a systematic review”, which we amended in accordance with the Reviewers‟ comments. We thank the Reviewers for their enthusiasm about the manuscript, and for the supportive and helpful comments. Our detailed response to the Reviewers‟...

With the growth in sociality and interaction around touching national and international topics, news sites are increasingly becoming places for communities to discuss and address issues spurred by news articles. Proponents of cyberspace promise that online discourse will increase political participation and pave the road for a democratic utopia (Papacharissi, 2004). Comment writers, according t...

Braille-character recognition is one of the foundational skills required for teachers of braille. Prior research has evaluated computer programming for teaching braille-to-print letter relations (e.g., Scheithauer & Tiger, 2012). In the current study, we developed a program (the Visual Braille Trainer) to teach not only letters but also numerals, punctuation, symbols, and contractions; we evalu...
