They consist of 4 arcs on which the motor and propeller are mounted. If you install four propeller motors on a light carbon fiber case, fiberglass or light wood and connect them to the remote control via a control board equipped with a gyro stabilization, you can get a simple drone with components that have almost endless designs. A quadcopter remote controlling softwareon the base of microcontrollers Arduino and ESP is created. The developed software product is a cross-platform application for quadcopter control, and the software developed for used microcontrollers can be easily modified and supplemented with new functions. In the development process, modern technologies were used, such as C #, XAML, Wi-Fi, UWP who proved they are reliable enough to use. The result of this work is the simplified creation of quadrocopter, including the use of cheaper components and the expansion of the quadrocopter functionality.","PeriodicalId":171656,"journal":{"name":"Scientific Notes of the State University of Telecommunications","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127467135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The corporate culture of a telecommunications enterprise is directly related to the national culture, which acts as a socio-cultural environment for the development of the former. On the other hand, the corporate culture of the enterprise significantly affects the values and attitudes of the national culture. It is substantiated that in the process of forming a strategy for proactive management of the corporate culture of telecommunications enterprises, the primary task is to coordinate the organizational structure (first of all, its main functions) with the main functions of the corporate culture of the enterprises. And this, in our opinion, can be considered a key stage in the development of the company's strategy in general, and the strategy of corporate culture management, in particular. It was determined that the principles of developing a strategy for managing the corporate culture of telecommunications enterprises should necessarily be supplemented with the principle of practicability, which will ensure the biased nature of the strategy. The relationship between the stages of diagnosing corporate culture and determining the current level of development of the corporate culture of a telecommunications enterprise has been established. He showed that diagnostic tasks meet the criteria for determining the current level of cultural development.","PeriodicalId":171656,"journal":{"name":"Scientific Notes of the State University of Telecommunications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116898978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, this problem can be formulated as follows: an unstructured database consists of elements and contains one unique element that has a certain property that can be tested with polynomial complexity, and which must be found with minimal time and complexity. Classical methods require querying the database to find the desired element, while Grover's algorithm allows you to perform only approximately steps, which are iterations of the procedure, to the database and be sure that the resulting element will be exactly the desired element with a probability close to 1. As in quantum algorithms aimed at cryptanalysis of symmetric transformations, Grover's algorithm repeats the procedure (Grover's iteration) to increase the probability of obtaining the correct result. Similarly to such algorithms in Grover's method, when iterations are continued after reaching the required number of iterations, the probability of obtaining the correct result decreases. This is due to the fact that during the execution of Grover's iteration, a rotation is performed in the complex space. Thus, each iteration, making a turn, brings the register closer and closer to the desired state, but at a certain point a maximum closeness is reached, at which the continued use of iterations will lead to a turn past the desired state, which will move the state of the system away from the desired state. The database for this algorithm can be any search space consisting of a certain number of elements. So, for example, it can be applied to find a secret key for a symmetric cryptograms formation or to find a collision for a hashing function.","PeriodicalId":171656,"journal":{"name":"Scientific Notes of the State University of Telecommunications","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128302372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the article is a receipt of estimation of unknown function of distribution of probability of successful unauthorized removal of confidential information in the conditions of self-reactance vagueness. As a result, the algorithm of construction of ortogonal rows is in-process presented for determination of estimation of laws of distribution of probability of successful realization of unauthorized removal of confidential information on the objects of informative activity in the conditions of self-reactance vagueness. On the example of radio frequency channel of information transfer the estimation of probability of successful removal of confidential information was practically carried out on an object of informative activity, that was determined as dependence of relation of exceeding of level of amplitude of informing signal to the thresholding on the basis of supervisions that was taken off in laboratory terms by means of oscillograph and comparator on the basis of integral microcircuit of LM339 of company Motorola. As a conclusion, the use of ortogonal rows is in-process shown for the estimation of closeness of distribution of probability of successful unauthorized removal of confidential information on the object of informative activity in the conditions of parametric vagueness on the example of radio frequency channel. It is noticed, that this algorithm is comfortable and informing, if a closeness of distribution of probability is a function from the small amount of variables(not more than three).

It is shown that the MU-MIMO specification is one of the most significant technological improvements to MIMO. At present, the standardization of mobile communication technologies to lay the foundations of wireless networks 5G, there is a general view of the need to replace the fundamental OFDM technology at the expense of more efficient, which can better operate in 5G conditions. For this purpose, a number of new forms of modulation have been introduced. It should be noted that at the same time, these methods have a basic principle of OFDM technology. The main idea of OFDM technology is to divide the frequency selective channel into a number of narrowband sub-channels. In these subchannels or subcarriers, orthogonal narrowband signals are transmitted in parallel. Since each of these signals undergoes shallow fading, then a fairly simple scalar correction of the channel. The main methods of promising technologies UF-OFDM, FBMC, and GFDM are described, which are logical continuation of OFDM-modulation development. In many ways, FBMC has much in common with CP-OFDM and OFDM, which use a cyclic prefix as a security signal. GFDM is a flexible multi-carrier transmission method, which is largely similar to OFDM. UF-OFDM uses filtering to provide its unique characteristics.","PeriodicalId":171656,"journal":{"name":"Scientific Notes of the State University of Telecommunications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129430282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, in the age of high information technologies, there is a rapid growth in the volume of information flows and, as a result, the formation of new knowledge and methods of activity with the help of video content. Therefore, the problem of increasing the efficiency of using software for creating high quality video content becomes urgent. Editing of high-quality video content is associated with the need to sort and store various segments or fragments of a video sequence in the process of processing or restructuring the source material for subsequent intra-frame or between frame editing. Naturally, high quality video content has a significant amount of data and takes up a lot of storage space. Hence, the problem arises of finding methods to increase the efficiency of using software for creating high quality video content. To solve this problem, a systematic analysis of the video content production process was carried out, a certain problem of editing (composing) as the need to reduce the editing time in the process of processing or restructuring the source material as a condition for increasing the efficiency of the video content editor. Analyzed from the point of view of technical and software video editing procedures, namely: special effects, do video correction, cutting, joining, applying various transitions, overlaying and editing sound and others. Consider the types of video content editing: linear or non-linear, and their components: parallel editing, accent editing, intra-frame between frame editing.
