Пропедевтика параллельных вычислений в школьной информатике: тема «Рой роботов» в конкурсе «Тризформашка-2017»
The article is devoted to the preparation of methodological materials for the inclusion of the topic "Parallel computing" in the school course of informatics. The set of tasks for the division "Swarm of Robots" are considered. The tasks were tested at the competition "TRIZformaska-2017" - an inter-regional competition in informatics, system analysis and the theory of solving inventive problems (TRIZ) for schoolchildren and students.
Propaedeutics of engineering culture in the school should not be limited by familiarity with the school robotics. It is necessary to the development of other components of the engineering culture, such as TRIZ, system analysis, project management, and others. The possible content of these components and the ability of their studying in the "Permian version" of a propaedeutic course of computer science ("TRIZformatics") and contest "TRIZformashka" are discussed.
The problems of identifying latent parallelism in the algorithm by explicitly max (the construction of stacked-parallel form of the algorithm graph) and implicit (the method of streaming - DATA-FLOW - calculations), the development of parallel programs in the MPI-paradigm programming and quantitative research strength calculations for the acceleration parallelization on the parameters of a multiprocessor system and the quality of parallel programs. The manual is practical and can be used by students to prepare for the performance of laboratory and practice of the works, of course and diploma projects.

Students' internet usage attracts the attention of many researchers in different countries. Differences in internet penetration in diverse countries lead us to ask about the interaction of medium and culture in this process. In this paper we present an analysis based on a sample of 825 students from 18 Russian universities and discuss findings on particularities of students' ICT usage. On the background of the findings of the study, based on data collected in 2008-2009 year during a project "A сross-cultural study of the new learning culture formation in Germany and Russia", we discuss the problem of plagiarism in Russia, the availability of ICT features in Russian universities and an evaluation of the attractiveness of different categories of ICT usage and gender specifics in the use of ICT.
In this paper we consider choice problems under the assumption that the preferences of the decision maker are expressed in the form of a parametric partial weak order without assuming the existence of any value function. We investigate both the sensitivity (stability) of each non-dominated solution with respect to the changes of parameters of this order, and the sensitivity of the set of non-dominated solutions as a whole to similar changes. We show that this type of sensitivity analysis can be performed by employing techniques of linear programming.
