  • On about the features of UAV control systems with flapping wing

    In the article a number of approaches to a flapping wing pilotless vehicle control system synthesis are analyzed. Referred type of pilotless vehicles is possessed of a number of advantages compared to the traditional schemes, but requires a special approach to control system creation because of strong nonlinearity and multicoupling of a controlling object mathematical model. As a result of a control system synthesis approaches analysis a synergetic approach was marked out as the most adequate for the mentioned above type of controlling objects. An idea of prognostics application for the goal of reaching of adaptive control is also set forth. In this case parameters of an object of control and parameters of ambient both are to be forecasted whereby an adaptive behavior of an object of control is expected to be achieved.

  • Information content of the frequency characteristics of N-gram of the websites text fragments for search systems

      The work in the Internet is impossible without the use of search systems. The quality of the responses to user’s requests to a large extent depends on the keywords. However, due to some circumstances the user is not able to accurately enough to formulate a request and the number of received responses is great. In these situations, additional feature relevant answers selection can be text documents belonging to a particular implicit group. Implicitness group is shown in the fact that the text belongs to it is determined not by direct comparison with the reference (key) words, but by matching the semantic features, the wording of which is absent in the search text. Implementation of text classification can be made on the basis of the frequency characteristics of N-grams. The purpose of the work is to assess the possibility of using the frequency characteristics of N-gram of the websites text fragments to improve search engine based on a study of their information content. In this work designed a method based on the selection of informative indicators of N-gram with low computational requirements and with application of the correlation analysis. Based on its application has been shown that the frequency characteristics of N-grams have sufficient information content to improve search engines. The developed method has many common with systems of writing, because it relies not only on the alphabetic systems.
