Technological Transfer

In the context of the need for sustainable development of the national economy and joining the group of leading countries — technology suppliers, the organization of a technology transfer system, which ensures the transition of the results of innovative activities from the stage of scientific research to the stage of practical application, becomes one of the most important tools for the scientific and technological development of the country. Technology transfer is a rather complex system with a sufficient variety of participants and resources, which are the “tool of the initiative and communication plan” that promote and are necessary for continuous innovation in the modern economy. The tools and mechanisms of technology transfer are discussed in the article, a model for the implementation of international technology transfer in UkrISTEI through the Automated system for the formation of interstate information resources, the International technological platform for the technology transfer of collective use, the Interregional Office for the Transfer of Knowledge and Technologies, the Open Innovation Platform was presented; these objects are participating parts in export and import of innovative technologies and form a modern mechanism for the transfer of these technologies between countries. The process of technological transfer necessary to assess the benefits obtained as a result of technology transfer and ways to achieve these benefits has been investigated. The authors of the article presented the relevance of scientific research in the field of technological transfer, which is explained by the following reasons: effective organization of the technology transfer process contributes to an increase in the implementation of state innovation programs in relation to the modernization and innovation of the real economy; technology transfer facilitates the continuous movement of research and development results (projects) into the industrial sector of the economy; the efficiency of technological transfer makes it possible to accelerate the formation of scientific, technological and industrial ties, as well as to strengthen the position of national production in the world market of science-intensive developments.

Introduction of the “Automated system for operational control of casts production (OCCP AS)” makes the basis of an integrated automated production control system (APCS). It performs three main tasks: control and recording (production, products, materials, etc.), improving quality of casts and operational management of technological processes. Solution of these tasks was accomplished through automating data collection in real time for all production operations, recording material flows, creating operational communication channels, as well as centralized collection, processing and representation of data by the process information server. The next step in building an effective automated control system is to stabilize product quality in changing external conditions, for example, quality of materials, and to optimize production (technology change in order to reduce costs for constant or higher product quality). The second stage is based on mathematical processing and analysis of data coming from OCCP AS, it allows to determine optimal ranges of parameters of technological processes  – “Automated system for optimization and analysis of production progress (OAPP AS)”. OAPP AS consists of two subsystems: quality analysis and technology management. The first solves the problem of data analysis and modeling, the second – calculation of real-time optimal process parameters and real time prediction. The stages tasks compete for access to different hardware resources. The most critical parameter for OCCP AS is performance of server disk arrays, for OAPP AS it is processor performance. In either case, system scaling is effectively solved by parallelizing operations across different servers, forming a cluster, and across different processors (cores) on the same server. To process defect images and to obtain cause-and-effect characteristics, you can use OpenCV software package, which is an open source computer vision library. In course of processing, Sobel operator, Gauss filter and binarization were used. They are based on processing pixels using matrices. Operations on pixels are independent and can be performed in parallel. The task of clustering is reduced to definition of an expert method or using various mathematical algorithms for defects belonging to a specific cluster (data block) through a set of values of dependent factors. Thus, data blocks are formed by the criterion of the defect cause. Calculation of a data block to which a product defect belongs can be very resource-intensive operation. To increase efficiency of image recognition systems and parallelization ofsearch operations, it makes sense to place data clusters on different servers. As a result, there is a need for a distributed database. This is a special class of DBMS, which requires appropriate software. Generation of OAPPAS based on a multi-node cluster with ApacheCassandra DBMS installed and using Nvidia video cards supporting CUDA technology on each node will be the cheapest and most effective solution. Video card is selected based on required number of graphics processors on the node.

Currently, the means of measuring and converting information signals from equipment are widely used in industrial processing systems. For the most part, modern systems of mechanical processing of materials use mainly single-channel systems that work on information signals that identify the physical parameters of the technological process. Such a narrow specialization of monitoring one of the parameters usually reduces the reliability of the results obtained and, as a consequence, the reliability of the entire control system. The task of the work is to determine the possibilities of creating the foundations of the automated system on the basis of multi-channel information recording devices from processing equipment and possible approaches to the choice of criteria for the analysis of fluid information. As a result of the given analysis of a condition of branch and its modern transformations, the module of system for data collection on process (from a set of sensors) is offered for development, with a possibility of their further transformation on certain dependence, storage, transfer, and a possibility of signaling of certain events, for example, faults, for use in production automation systems and for equipment not included in the systems. At the same time, the multi-channel device of the sensor system provides opportunities to determine the full amount of information about the process. The basic modern means of control of work of technological processing CNC-equipment applied in the industry are investigated. The most perspective directions of development of multicriteria methods and automated control systems of technological equipment in the part of creation of complex sensors are determined. These sensory complexes register signals that are different in physical phenomena. The main approaches to the creation of control systems provide opportunities to build a theoretical basis given the logic of the system of obtaining specific information data in the automation of technological processes. Promising research at creating algorithms for such complex systems of quality control and diagnostics of technological processes can be aimed.

A study of the flammability of fabrics involved in wearing-apparel fires was conducted co-operatively by the American Academy of Pediatrics Committee on Accident Prevention and the National Fire Protection Association Committee on Wearing Apparel. A total of 124 fabric samples from 84 accident cases were tested. Of the 124 samples, 94 were of cotton exclusively, bearing out the previously known, but widely unrecognized, fact that cotton is the most flammable of fabrics. All met the currently established standards of normal flammability for fabrics. Other data obtained in the study included age of patients (a total of 84, of whom 41 were children and 7 were aged persons); type of garment (40% were pajamas, nightgowns, bathrobes, or housecoats); and source of ignition (more than half were stoves, heaters, furnaces, or fireplaces). The relative flammability of fabrics are discussed, with attention to the fiber and the weight and weave of the fabric. Other factors influencing wearing-apparel fires include the type and style of garment; the age of the person involved; and the availability of a source of ignition. Legislation concerning standards of acceptability for the flammability of clothing fabrics are outlined, as are the standards of the National Fire Protection Association. The need for a public education program about the hazards of clothing fires is delineated. Current research in the field of chemical flame retardants for fabrics is outlined. Possible steps for reducing clothing fires are listed, with special attention to the pediatrician's role.

New Information

Steady requirements of consumers to the quality of to the development of automated systems, make it necessary to the information provided, on the basis of which the control actions constantly process or create higher quality products. The require-are carried out, as well as the acceleration of technical means related ment to improve the basic information solutions using modern technical resources offered by industry was the reason for the rework of the existing business process for managing the fleet of passenger cars implemented in the automated system for managing operation and repair of the passenger car fleet (ASUPV). The article gives a brief analysis of the 20-year work of the linear enterprises (LP) with the ASUPV - (ASUPV LP) subsystem, with the help of which the source documents are entered into the car park, trains are formed and the passenger car fleet maintenance is monitored. This subsystem is the main supplier of information for obtaining analytical data at all levels of passenger car fleet management. The article also outlines the main goal of the new information technology - obtaining, through single processing of primary data, new quality information, on the basis of which optimal management solutions should be developed. The purpose of the newly developed ASUPV LP-2 system is to automate the technological processes of centralized management of the passenger fleet of linear enterprises to improve performance and efficiency of the industry, which will allow optimizing the work of passenger line enterprises, monitoring compliance with technological processes and ensuring the availability of reliable information to interested users. The article describes the main tasks of the developed system: ensuring the need for the necessary and sufficient number of passenger cars for the fulfillment of the transportation plan at the linear enterprise; creating of guaranteed traffic safety of the formed passenger trains; improving the quality of repairs and maintenance. It is noted that the sources of increased complexity of managing the passenger car fleet are the constantly increasing complexity of business processes automated at the linear enterprise, which conflicts with the existing regulatory and technological base, as well as increasing requirements for the speed and accuracy of execution of all operations with cars. It is also indicated that automatic monitoring of the input sequence of source documents and its information interconnection should be created in the developed system and a system of automated control and prevention of conscious violations performed by users should be developed in order to improve the performance of their own work. The system should control the user's actions as much as possible and check the information entered by the user for compliance with regulatory requirements.

The article is devoted to the theoretical foundations of improving the engineering support of railway construction. One of the main purposes of the existing engineering support system is to evaluate the results of development and monitor the implementation of technological processes for the construction of railway facilities. In the course of the study, it was determined that a number of stages in the development and implementation of technological processes contain tasks for which the use of automated design and control systems is sufficient. However, there are tasks whose solution depends on the experience and intuitive abilities of the engineer (developer of organizational and technological documentation). To solve such problems, in addition to settlement procedures, logical ones are also necessary. In addition, the intensification of railway construction, many restrictions on the production of works and resources, as well as deviations from planned indicators, require prompt decision-making aimed at compliance with design requirements. Obviously, the total amount of information and data on the design and actual technological processes does not guarantee the efficiency and rationality in decision-making by an engineer. In this case, to solve technological, organizational and managerial tasks, it becomes possible to use some methods and means of artificial intelligence. In this regard, it was proposed to supplement the existing system of engineering and technical support for railway construction with a subsystem of engineering and intellectual support for the technological process of constructing a railway track. For the purpose of intellectualization and the formation of a new paradigm of engineering support for railway construction, an analysis was made of modern and promising practices in the development and implementation of technological processes from the perspective of the life cycle of a railway track object. It was found that modern technological processes for the construction of railway facilities should be flexible to changing working conditions. The study showed that this can be achieved through the formation of adaptive digital technological regulations. The basis of the digital regulation is the information model of the technological process. The model formation procedure is divided into stages containing tasks, the solution of which is possible using artificial intelligence tools such as expert systems, artificial neural networks, and genetic algorithms. A fundamental feature of the engineering and intellectual support of the technological process is the possibility of its operational regulation based on the results of monitoring its development over time. A feature of this approach is the need for the operational processing of a large amount of data that determine the development of technological processes over time, the conditions of work, the production capabilities of construction (contracting) organizations. For this, the mathematical and conceptual models of an intelligent automated system have been developed. Its main purpose is the operational solution of the problems of development and implementation of the technological process of construction of railway facilities. The results obtained during the study, as well as the developed tools, made it possible to determine the possibilities of integrating the developed methodology into the existing system for designing and managing the construction of railway facilities. The results given in the article were obtained during the dissertation research performed by the author.

The essay examines different cases of bioart, which, by combining biological materials and technological processes, present new forms of biological assemblages. For example, such collectives as Tissue Culture and Art Project and Art Orienté Objet, artists Eduardo Kac, ORLAN, Maja Smrekar and Robertina Šebjanič invent new forms of hybridization and symbiotic forms of cohabitation. The essay will question what is so specific in bioart and in what respect does it differ from scientific research conducted in laboratories, or fromsome biological phenomena found in the natural world. My hypothesis is that bioart introduces a specific mode of bio-performativity and creates a unique moment of bio-presence: it does not represent but presents and produces new material bodies, which are living and decaying in our presence. The essay will seek to discuss the specific time in which these Semi-Living objects perform their existence: this time, which is “the time of the now”, can be called (in Giorgio Agamben’s terms) kairos and contrasted with our habitual chronological time.Kairos is a messianic time, a contraction of time (similar to time in specific laboratory conditions), which helps to imagine new ways of organizing living materials. In this sense, bio-presence and bio-performativity can be seen as a resistance to the habitual arrangement of space and time and its biopolitical implications

The problem of safety provisioning in technological processes, which aims the reducing the probability of accidents is considered. Classification of technological process states from the point of view of accident prevention system is offered. The set of such states consists of: normal functioning, pre-emergency, emergency and accident. The state of normal functioning and pre-emergency state assume the absence of irreversible changes in the technological processes. It is considered the case when the operator has to form some management actions which are aimed to stabilize the process, when the process is in the pre-accident state. It is shown an example of a data flow diagram, which includes also the human operator, the tracking system, and the system of manual and automatic control in additional to the standard components of such systems. By using the data flow diagram, it is defined the sequence of stages which occur when the process in transferred from the pre-emergency states to the state of normal operation. A method for assessing the possibility of transferring a technological process from a pre-emergency state to a normal operating in proposed. This method consists in estimating the time relation between the available and the necessary for stabilization of the system. The time required for stabilization consists of the time delay of the measuring device, the latency of the operator and the response time of the actuator. The delay time of the measuring device and the response time of the actuator are determined by the conditions of the technological process. The model for estimating the latency of the person is based on the law “force-time” is developed. A study of the boundary cases of the formula for estimating the available and the necessary time is carried out. Stimulation modelling is conducted, which results are used to estimating the ways of optimizing the technological process in order to improve the reliability of the accident prevention system.
