The paper considers the nature of input data used by Data Science algorithms of modern-day application domains. It then proposes three algorithms designed to remove statistical anomalies from datasets as a part of the Data Science pipeline. The main advantages of given algorithms are their relative simplicity and a small number of configurable parameters. Parameters are determined by machine learning with respect to the properties of input data. These algorithms are flexible and have no strict dependency on the nature and origin of data. The efficiency of the proposed approaches is verified with a modeling experiment conducted using algorithms implemented in Python. The results are illustrated with plots built using raw and processed datasets. The algorithms application is analyzed, and results are compared.

The aim of the research was to detect the biological activity of aqueous solutions of various samples of amber from the Trancedniestria province, and to characterize their effect on the physiological processes of higher plants. The allelopathic and cytostatic effects of amber solutions were studied using biotesting methods in open soil conditions and in culture in vitro. The test-object was the seedlings of cucumber Cucumis sativus L. It was shown that the activity and nature of the action of the samples depend on the region of origin of the amber, the degree of shredding and concentration of the solution. According to the results, fine fractions of amber show biostimulating effects on plants. Thus, amber and its aqueous solutions can be effectively used for cultivating agricultural plants in vivo and in vitro conditions. For stimulation of the increasing of the plant stem mass it is recommended to use amber B1, to increase the mass of roots - amber B4, and amber B2 - to stimulate stem growth in length.

Nowadays myocardial infarction has a high percentage of mortality [12], and is widespread inUkraine and Western countries [1, 2, 3]. Such a situation calls for the development of a new model of myocardial infarction, which would be as simple and effective as possible. In this article, a model of myocardial infarction with the use of inhalation anesthesia with chloroform is proposed.

Purpose. Investigation of the operation of power equipment of traction substations (TS) of Ukrainian electrified railways. The search of the new modern methods and approaches improved monitoring, diagnostics and maintenance of power equipment TS during operation to maintain the required level of reliability of the traction power supply of electrified railway and limit the power equipment accidents TS. Methodology. The study of changes of a technical condition of TSs’ equipment over the last 11 years was done for achieving this goal. This research was done for solving problems of power supply railways with high quality on the base of the reports analysis of the management and power supply of Ukrzaliznytsia. Findings. It was found that on the base of the new methods of maintenance is the risk analysis of old equipment or equipment with some defects (rev servicing equipment for the actual technical condition).Reliable performance of power supply devices has significant impact for solving the problem of safety on the railways of Ukraine. Different kinds of accumulated damage are at the first place before of failures of an electric power supply of electrified railway. The study of main causes of violations from 2002 to 2012 year showed that 80% of the reasons disorders normal operation of the traction power supply over the period constitutes next factors. There are damage to the main power equipment TS; power off the grid; overload and surge; and the impact of weather conditions. The primary power equipment failure of TS are constituted about 43%. Relevant constant monitoring, testing and diagnostics of the equipment with the creation and use of micro-processor smart automated monitoring and diagnosis are topical in the current operating conditions. Originality. The new directions for further improvement of maintenance electrified traction substations for electrified railways were considered. Modern strategies and management techniques and maintenance TS electrified railways of Ukraine were proposed at the first time. This methods aren’t covered in the "Instructions for maintenance and repair of equipment of traction substations, power points and sectioning electrified railways’ IT-0024. The basic problems for implementation of these strategies were identified. Practical value. It was established that system outage under tight central planning and management in the new economy does not provide, in many cases, approval and adoption of effective and optimal solutions in organization and carrying out maintenance. It was investigated that a significant portion of electric power equipment of TS even after normative life maintains its performance under the terms. There are allowable stress regimes, timely testing, diagnosis, maintenance, repair and quality of execution; on the other hand the service life of electrical equipment depends on its residual life.

Purpose. The new methods development for improving the maintenance service for equipment of traction networks in order to increase its efficiency and quality. Methodology. In world practice of solving problems related to the quality of products and services is usually achieved by introducing quality management system in to the enterprises. The provisions of quality management system were used for solving the problem. The technologies of process engineering were used for describing the main stages of maintenance service. Findings. The development of high-speed movement and growth of its intensity, the use of electric rolling stock of a new generation require the introduction of new methods diagnostics of equipment technical state and improvement of the existing maintenance system and repair of power supply. Developing a model of business-processes, their optimization with using techniques of process engineering and system management is needed for the transition to the management system based on the process approach. From the standpoint of the process approach and in accordance with the requirements of the quality management system (ISO 9001-2009), the operation of the E (Department of electrification and power supply) infrastructure sector is represented as a scheme of business-processes in which the guaranteed supply with electricity of railway and third-party consumers is defined as the main business-process of management. Each of the sub-process of power supply for consumers is described in details. The use methods and main stages of process approach for sample management system reorganization were investigated. The methodology and the application method of PDCA (Plan-Do-Check-Act) closed loop to the equipment maintenance system were described. The monitoring process of traction networks maintenance using the process approach was divided into components after investigations. The technical documentation of maintenance service was investigated in details. Ways to improve business-processes of E (Department of electrification and power supply) management were described. Originality. Maintenance improvement ways for equipment of traction networks using process engineering technologies and quality of electric power supply were proposed. Practical value. Using the provisions of the quality management system to the process of maintenance equipment will let ensure the improvement of process quality by increasing the reliability indices of electric equipment, the service level of consumers and changes of production processes focused on the efficiency increase of the sector activity.
