Relevance of the work is related to the priority of the new educational paradigm, learner-centered, which aim is to provide the development of personality , the formation of its value-semantic sphere and give the opportunities for self-development and self-realization. Value-semantic sphere of educational activity subjects, in our study students of different ages and directions, is a key factor in learner-orientated education. Semantic formations as motivational-semantic and value sphere manifestations of the personality are dominant in the regulation of human vital activity (Abakumov IV) and extend the content of the training process- as a special form of culture, as "crystallized meanings" (Leontiev). The aim of our article is to study value-semantic sphere of of educational activity subjects, in our study, students of different ages and directions.

We construct an example of blow-up in a ”ow of min-plus linear operators arising as solution operators for a Hamilton…Jacobi equation @S/@t+|∇S|/ + U(x, t) = 0, where > 1 and the potential U(x, t) is uniformly bounded together with its gradient. The construction is based on the fact that, for a suitable potential de“ned on a time interval of length T, the absolute value of velocity for a Lagrangian minimizer can be as large as O(log T)2−2/. We also show that this growth estimate cannot be surpassed. Implications of this example for existence of global generalized solutions to randomly forced Hamilton…Jacobi or Burgers equations are discussed.
A multivariate generalization of the classical collective risk model is considered. In this model in which each component is dependent on the others.The exact solutions and asymptotic approximations to the probability of ruin were obtained.
In this paper the modification of McEliece public-key cryptosystem is considered, which uses the codes based on Plotkin construction as the private key, instead of Goppa codes traditionally considered for this purpose. Proposed modification allows strengthening of McEliece cryptosystem by attacks complication based on the secret code structure.
In this paper an attack on McEliece cryptosystem is considered. In this system the private and public keys are generator matrices of equivalent codes, i.e. they differ by fixed (secret) permutation. At the same time it is known that for every code there are the group of permutations preserving the code. Such code's structure may be used for analysis of McEliece cryptosystem.
One of the actively developing approaches of group robotics systems creation is the use of social behavior models. Aggressive behavior is one of the underlying mechanisms forming social behavior. In this paper, the application of aggressive behavior concepts is considered by analogy with animal aggressive behavior that can be used for solving tasks of group robotics. As a role model, an ant – a true social insect – is proposed. It was shown that in aggressive behavior of ants, the numerical factor and imitative behavior play an important role. Agent’s aggressive behavior model depending on accumulated aggression and the number of other nearby agents is proposed. The results of computer experiments for territory defense tasks are presented. The results show that aggression is a stabilizing factor for an approximately equal number of agents in different groups. By an increase in group size, aggression becomes a way of capturing foreign territory.
The conflict measure and index of decreasing of igno-rance in frame of Dempster-Shafer theory are intro-duced. Those functionals are analyzed on the bodies of evidences of special type. It is shown that the great correlation between the bodies of evidence is a sufficient condition of decreasing of ignorance after the applying of combining rule. The relationships between the measure of conflict and the index of decreasing of ignorance in the case of different types of evidences and the application of different combining rules were investigated.
