  • On image masking as the basis for building a visual cryptography scheme

    The features of the (m,m) implementation scheme of visual cryptography are considered, which differs from the existing ones by the formation of shadow images (shares) of an image containing a secret. The proposed approach is based not on the decomposition of the secret image into shares, but on their step-by-step transformation by multiplication by orthogonal Hadamard matrices. The images obtained during each transformation of the stock are noise-resistant in the data transmission channel.

    Keywords: image with a secret, image decomposition, image transformation, orthogonal Hadamard matrices, two-way matrix multiplication, noise-resistant image encoding

  • Solutions to optimize the process of collecting and recycling plastic waste in the ocean

    The article discusses the issues related to the solution of an actual problem – the recycling of accumulations of plastic waste in the ocean. It is proposed to organize the plastic recycling process directly in the ocean on recycling vessels. At the same time, the products of mechanical processing and pyrolysis can be used to support the construction, road construction, and electric power industries of coastal developing countries in Africa and Latin America, near which the largest amount of plastic waste is concentrated. It is proposed to use both systems with artificial intelligence trained to recognize and identify plastic by shape, and systems based on spectral analysis of the composition of plastic for sorting and identification.

  • Enrichment of a sequences set in the problem of blocks of symmetric Hadamard matrices searching

    The search for orthogonal and quasi-orthogonal matrices is considered as a sequence of setting initial conditions, choosing an implementation method, filtering a set of generated sequences. It is proposed to accelerate the search for matrices by pre-fixing their structure and filtering the generated sequences using the Fourier spectrum. Fixing the structure involves using the symmetry properties of the desired matrices. Filtering allows you to exclude sequences with explicit spectrum outliers when forming blocks of symmetric matrices.

  • The concept of control method of the tracking camera of a rotary-wing aircraft based on the theory of fuzzy sets

    The basis of solving the problem of automatic takeoff and landing of helicopters is the problem of orientation of the aircraft relative to the landing site. Existing approaches are based on a combination of satellite positioning technology and sensors. Such solutions have a significant drawback - low positioning accuracy. In this regard, it is necessary to develop new methods that provide low computational complexity and high positioning accuracy relative to the landing site. The article provides an overview of modern solutions in the field of autonomous control of aircraft. The concept of a method for solving the problem of orientation of a helicopter relative to the landing pad is proposed. The approach is based on the use of a camera following the heliport sign. Determining the landing site is based on the theory of fuzzy sets and complex linguistic variables. Complex linguistic variables have three-dimensional membership functions, thus avoiding the problem of uncertainty. Simplification of the computational process is achieved through the use of projections of sections of three-dimensional membership functions.

  • Acceptance (tecnical) documentation requirement for construction facilities in oil production field

    Over the last years there is much concern about the quality of execution and selection of the actual documentation in the registration proceeding of the facilities construction turn-over package. There is no exact consolidated catalog of as-built documentation in the new normative and technical literature. Each executive document represents as an application to various sources of regulatory and technical literature. Therefore, the article presents a divided into chapters detailed catalog of as-built documentation for the oil and gas facility construction. An explanation is given for each chapter for which purpose it is formed and what function it has in the general package of as-built documentation. The main aspects of the as-built documentation execution are considered, a list of the documentation and some recommendations on the facility commissioning to the Client are given. Additionally, there is a suggested recommendation on the execution and filling of the package (folders) of the construction as-built documentation. This article recommends a common procedure for filling out and arrangement of the document flow of PTW package and as-built documentation of construction and installation works and the commissioning of the capital construction facilities. The article clearly describes the goals: - Improvement of the quality of as-built documentation execution; - Organization of the process of preparation, making up and verification of the package contents and quality of turnover documentation for construction and installation works; - Conducing the as-built documentation to a uniform style, which provides a high degree of the documents identification and control over the execution of the quality of preparation and completeness of the turnover documentation for works and construction projects; - Making-up of the objects reporting documentation; - Making-up of a document collection of the objects and work performed; - Establishing of universal explanation of the normative requirements by the all participants in the construction process. The focal point of this article is to provide recommendations on the execution of the turnover documentation for the facility construction, as well as improving the quality of as-built documentation execution. This article is action-oriented and is aimed to help young professional of the production and technical department of contracting companies, specialists of the Capital Projects Department, construction control and customer companies.

  • Model of an intellectual information system for recognizing users of a social network using bioinspired methods

    Today one of the topical issues is the practical application of the theory of pattern recognition, face recognition, including the definition of a person in the image and its subsequent identification. Such tasks include the extraction of indirect signs of interaction between users of social networks. By identifying the user's face and further searching it in photographs and video files in other profiles, an expansion of the list of basic data available to the analyst is achieved. It is known that the system of computer vision, which is able to recognize faces in a natural and artificial environment under any conditions, has not been implemented to date. One of the obstacles is the variation of the scene - the area where the face is being identified. The article proposes a model of an intelligent information system using bion-spirited methods for preprocessing images in order to expand the range of allowable scene variations.
