Evaluation of graphic data corruptions impact on artificial intelligence applications
Authors: Molokovich O , Morozov A , Yusupova N , Janschek K 
Published: March 2021

Abstract
The article is devoted to the problem of the reliability of applications based on artificial intelligence. The authors made an attempt to evaluate the impact of the graphic data distortion at the input of a convolutional neural network on the result of image classification. The experiment is based on the fault injection method. A series of independent tests were carried out for such distortions as Gaussian noise, salt and pepper, speckle and Poisson noise, as well as median blur, motion blur, scene brightness changing, rotation, rain, and snow. The results showed that Gaussian noise was the least critical distortion; environmental conditions (rain, snow, brightness) and image rotation up to 20 degrees are less critical than focus losing and motion blur, while the most critical distortion is speckle noise. It was verified that preprocessing the input data of the neural network improves the accuracy of image recognition.

Designing a biometric access control concept
Authors: Troshkov A A , Bogdanova S V , Ermakova A N , Rachkov V E 
Published: March 2021

Abstract
The current legislative and regulatory database of biometric characteristics for the security of information technologies is not informative and has an imperfect system. The main disadvantages include: the lack of system and methodology for building biometric identification/authentication for managing access to protected information resources; insufficient knowledge of all possible biometric characteristics of a person; an imperfect model of the biometric system; a static approach to assessing access control. Therefore, there is a need to develop a biometric identification/authentication system to restrict access to information resources in various areas. Accordingly, we propose to systematize the biometric system for protecting and managing access to information.

Hardware, Biometric and Passwordless Authentication: Vulnerability and Cybercrime Issues
Authors: Chebotareva Anna A. , Chebotarev Vladimir E. 
Published: March 2021

Abstract
The problem of identification and authentication is relevant. In conditions of crisis manifestations, including in connection with the pandemic, the number of fraudulent actions on the network is increasing, aimed at taking over information -personal data, bank card data, other important information. This raises the question of identification and authentication. At present, in Russia and in the world, some approaches to methods, protocols, and standards of authentication have been developed. Hardware, biometric and passwordless authentication are some of the most promising areas. However, no holistic approaches have been developed to the essence and main directions of development of authentication aimed at reducing vulnerability, which does not contribute to overall security on the Internet. In general, this issue assumes an interdisciplinary approach that takes into account both technical, social, political, economic factors, and, of course, an effective legal mechanism. In search of a solution to the problem, approaches to hardware, biometric and passwordless authentication in Russia and abroad are being investigated.

Authors: Petrenko V I , Tebueva F B , Antonov V O , Svistunov N Y 
Published: March 2021

Abstract
This article presents a method for decomposition and distribution of tasks in a multi-robotic system (MRS). The proposed implementation of the method of elementary operations distribution is based on maximizing the expected efficiency of each agent and collective decision making (CDM). To compare the effectiveness of various methods, computational experiments were carried out. According to the results, the implementation of the CDM mechanisms allows reducing the time for performing a global task by MRS agents by more than 10%. For the initial conditions described in the work, the use of the proposed method for maximizing the individual efficiency of an agent in combination with the CDM algorithm allows reducing the average execution time of a global operation by 21% in comparison with the method of minimizing the individual execution time without CDM.

Published: March 2021

Abstract
Forensic research in the investigation of information security incidents, the production of forensic examinations and many other areas of activity related to computer forensics require the maximum possible preservation of the integrity of the investigated data. To do this, write blockers are used - programs or devices that do not allow writing anything to the drive under investigation. The need to use such means comes both from the requirements of procedural legislation (for example, the Criminal Procedure Code of the Russian Federation), and from various recommendations of a methodological and other nature, as well as from standards (for example, STO BR IBBS-1.3-2016). Some aspects of the functioning of write blockers will be discussed in this article. And on the example of the criminalistic lock the question of influence of the used interface for data transmission in tasks of creation of images of data carriers will be considered.

Modern High-Rise Residential Complexes: the Modernization of Slums in the Formation of the Silhouettes of Capital Cities (on the Example of Baghdad)
Authors: Jasim S L 
Published: March 2021

Abstract
Urbanization as a socio-economic process manifested in the concentration of the population in modern big cities-especially the capitals - contributes to the development of high-rise residential complexes construction, which formation of the silhouettes of cities. City residents put forward new architectural and functional requirements to urban infrastructure. This calls for the creation of new types and forms of residential buildings, the structure of the city and transport networks. In addition, the need to develop high-rise building construction is justified by the growing demand for residential, public and administrative buildings and the lack of free space and the modernization of slums. Slums are a reality that many developing countries have to face. Despite all the efforts made to contain its growth, slums areas are increasing and it seems that removing them and providing formal housing for all its residents or at least compensating them for their investments is impossible, the modernization remains the best possible options in dealing with these areas. The paper analyses the modernization of slums in the formation of the silhouettes of capital city (Baghdad), by building modern high-rise residential complexes.

This paper is devoted to the problems of longevity of concrete maritime structures in climatic conditions of Russian Far Eastern seas. The subject actuality is stipulated with the plans of building of hydroengineering and transport structures in harsh climatic conditions under the program of modernization and expansion of the seaports capability in the Far East and development of the Northern Sea Route. It analyses the experience of hydroengineering structures building in conditions of Sakhalin Island seacoast during the period from 1920 to 2019 years. Character types of maritime hydroengineering structures by longevity considering service environment in corrosive mediums with the XF4 index are allotted and described. It mainly focuses to estimating of longevity by the results of predictive freezing-tests. Concrete’s qualitative reliabilities, deciding longevity of structures in hard service environment are analyzed. The data on actual frost-resistance of base (reference) composition concrete, which quality indexes have to ensure longevity at least 50 years in harsh climatic conditions, are cited. It is noted, that during the exploitation period increasing of qualitative indices of concrete is possible due to hardening and stabilization of concrete’s structure. It has been ascertained, that within the exploitation period concrete’s qualitative indices may increase due to its structure hardening and stabilization. It suggests the line of further investigations for methods preparation to predict structures service lifetime in hard service environment on the basis of the frost-resistance index of concrete and accumulation of experimental data on structures behavior in aggressive and harsh conditions.

Linking and Optimization of Construction Works
Authors: Kuzhin M , Postarnak E 
Published: March 2021

Abstract
Due to the complexity of the organization and management of construction of complexes of buildings and structures, it is necessary to come up with the simplest method for assessing the duration and volume of material and technical resources. This article developed a method for calculating the minimum duration in the Python 2.7 programming language. Standard methods of calculation use a priority coefficient, that is, the order of constructional production lines is built to minimize construction time for all the processes. The priority coefficient gives a duration close to the minimum, but does not reach it. Using the example of a small object with four constructional production lines and four processes, the difference between the previous method and the program is shown. The program was verified on a small dimension of a non-rhythmic in-line matrix with a heterogeneous rhythm. For a matrix with the number of rows more than 3, enumerating all sorts of variants is considered impractical. In the future, it is planned to use a matrix for one object to build a network model (graph) in which the basic input data will be described, objects and processes will be coordinated. This task significantly reduces the workload for calculating the duration, gives a reliable result for the preliminary calculation of the duration.
