Abstract: Disclosed are computer-implemented methods and systems for authentication of users through capturing and analyzing biometrics data such as keystroke dynamics. Once the keystroke dynamics is acquired, a corresponding feature vector related is calculated by calculating multiple sub-feature values using various algorithms such as normalization, relations between keystroke dynamics events, relations of sums of various sub-feature values, and so forth. The feature vector is then selectively compared to a group of reference feature vectors associated with the user. If it is determined that the newly obtained feature vector is similar to the selected group reference feature vectors, the user is authenticated. The process of determining similarity involves decomposition of feature vectors and reference feature vectors onto multiple sub-vectors and calculation similarity therebetween.

Abstract: A bracing system and method of its installation are provided. The bracing system includes a set of support panels and a set of crossover panels. The support panels may comprise connection members at their both ends such that these panels may be connected to each other in a line. The support panels are designed to be fixed in such lines to a beam. The beam should be provided with two parallel lines of interconnected support panels. The crossover panels are designed to link the support panels. The bracing system allows adding tremendous strength to wood beams in existing buildings.
