Research and software development using AR technology
The paper considers programs and devices of augmented reality, examines the general environments and methods of software development and the rationale for their selection. The work describes in detail the operating principle of the software, the pattern recognition algorithm, the UML class diagram, the UML usage diagram, and the architecture of the 3D rendering engine and a description of its operation. An example of practical application of software with pattern recognition is offered. The paper examines the impact of virtual reality on human health, as well as the problem of assimilation of educational material in preschool education. To solve the problem, various algorithms for the program are proposed. Based on the conducted studies, it was decided to create the software for the experiment on the basis of developed algorithms for preschool education. The results of the work can be used for further research in the field of expanded reality, for new developments in this field and improvement of the quality of education.
The practices of multi-actor child care is described and analyzed in the article. The empirical base is survey of Muscovites with children of 3 to 5 years old in November 2012. The results of the research have showed the significance of the kindergarten services as the institutional service that allowed parents to continue their professional careers. Along with that, the survey has revealed unequal distribution of child-care duties between mothers and fathers. According to opinions of parents, mothers are perceived five times as more involved into child-care than fathers. It is adjusted to the fact of different strategies of job search and placement. Mothers find a job with working hours that is in accordance with preschool schedule, fathers don’t taking into account this point. The policy of compensation for families which children don’t attend the kindergarten is discussed in the conclusion.
The volume contains articles of scientific staff and faculty of the Department of Computer Science and Applied Mathematics and Scientific-Educational Center of computer modeling of unique buildings and complexes of Moscow State University of Civil Engineering (National Research University), devoted to actual problems of applied mathematics and computational mechanics.
Human communication is basically the exchange of information. How can this be realized? Each communicant proceeds from a subjective perception of an objective reality; however in order to exchange information relating to this reality communicants are obliged to coordinate their perceptions. Each of us entertains personal experiences based on individual impressions and associations. But communication presupposes the presence of a common experience and the possibility of the coordination of subjective perceptions. It is presumed that communicants share common experiences: this seems to be the natural premise of communication.
How is this possible? How can I be certain, for example, that my interlocutor understands the words in the same way I do? How can we correlate our understanding? It seems obvious that the necessary condition of communication is an agreement between the communicants. But how can this agreement be reached? Where is the initial point of the coordination of individual experience of different persons?
The present book deals with this and related questions. Special attention is given to the role of deixis in the process of communication and to the mechanisms of linguistic comprehension.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Let G be a semisimple algebraic group whose decomposition into the product of simple components does not contain simple groups of type A, and P⊆G be a parabolic subgroup. Extending the results of Popov , we enumerate all triples (G, P, n) such that (a) there exists an open G-orbit on the multiple flag variety G/P × G/P × . . . × G/P (n factors), (b) the number of G-orbits on the multiple flag variety is finite.
I give the explicit formula for the (set-theoretical) system of Resultants of m+1 homogeneous polynomials in n+1 variables
