Authors: Nykyruy Yulia S. , Mudry Stepan I. , Kulyk Yuriy O. , Lapinski Marcin 
Published: January 2021

Abstract
Laser-induced local crystallization in Finemet-type alloy was studied using X-ray diffraction, SEM and EDX methods. For investigated conditions of irradiation (wavelength λ = 1.06 μm, laser power density 50 W/cm2), it was found that primary crystallization starts with the formation of the nanocrystalline α-Fe(Si) solid solution at shorter exposure time and the second step crystallization with the nanocrystalline hexagonal H-phase formation occurs in longer exposure time. Changes in the local element concentration were observed at the surface of the irradiated zone and at the ribbon fracture. It was shown that the nonlinear temperature field due to the laser irradiation resulted in changes of the local elements concentration and this feature changed crystallization mechanism of the Finemet-type alloy.
New Approach of Costs of Quality According their Trend of During Long Period in Industrial Enterprises in SMEs
Authors: Teplická Katarína , Hurná Soňa 
Published: January 2021

Abstract
Very important in SMEs is to monitor cost of quality and economic indicators for valuation of cost effectiveness. The main goal of this article is to create classification on cost quality categories in SMEs and to analyze economic quality indicators and their trend during long period. In this article authors use economical and statistical indicators for costs of quality. We use common model PAF, that include prevention costs, evaluation costs, internal failure costs, external failure costs. Total costs, individual simple cost index, cost ratio and cost structure were used. We analyzed data from 50 small enterprises with 10-40 employees with their yearly turnover max 3 mil €. The research sample of enterprises was focused on industrial areas of business such as engineering, metallurgy, automotive industry. We analyzed the quality costs in SMEs by the average value of quality cost in all surveyed enterprises. Results of this research brought labeling of cost of quality in SMEs by model the PAF for 10 categories for various enterprises, what is very important for comparing of results of QMS in SMEs. Based on the reference indicators of the total costs of quality in SMEs we can conclude their drop. Reducing the costs of quality was reflected in particular in reducing the costs of internal and external errors. In assessing the economic efficiency in SMEs plays an important role the overall cost that were increasing in reporting period. Very important result is that the cost of quality did not influenced overall cost. This fact is positive for competitiveness in SMEs because it shows a quality of production and product. Reducing of cost of quality brought improving of product quality; reduced customer’s complaints brought financial savings. The economic efficiency indicator shows a value above e > 1. It means that, despite rising cost enterprises generate revenues that are significantly higher than the input factors of production. Cost effectiveness helps to improve TQM performance.

Published: January 2021

Abstract
Environmental threats of coal usage in the electricity production combined with the consumption of renewable and non-renewable resources had led to worldwide energy challenges. The cost of coal mining and economical and environmentally sustainable usage of mined coal could be optimized by efficient management of coal supply chain. This paper provides a mathematical model for improving coal supply chain sustainability including the cost of exergy destruction (entropy). In the proposed method, exergy analysis is used to formulate the model considering not only economic costs but also destructed exergy cost, while genetic algorithm is applied to efficiently solve the proposed model. In order to validate the proposed methodology, some numerical examples of coal supply chains are presented and discussed to show the usability of the proposed exergetic coal supply chain model and claim its benefits over the existing models. According to the results, the proposed method provides 17.6% saving in the consumed exergy by accepting 2.7% more economic costs. The presented model can be used to improve the sustainability of coal supply chain for either designing new projects or upgrading existing processes.

Published: January 2021

Abstract
The article discusses methods for accelerating the operation of convolutional neural networks for autonomous robotics learning. The analysis of the theoretical possibility of modifying the neural network learning mechanism is carried out. Classic semiotic analysis and the theory of neural networks is proposed to union. An assumption is made about the possibility of using the symmetry mechanism to accelerate the training of convolutional neural networks. A multilayer neural network to represent how space is an attempt has been made. The conclusion was based on the laws on the plane obtained earlier. The derivation of formulas turned out to be impossible due to the problems of modern mathematics. A new approach is proposed, which involves combining the gradient descent algorithm and the stochastic completion of convolutional filters by the principles of symmetries. The identified algorithms allow increasing the learning rate from 5% to 15%, depending on the problem that the neural network solves.

Published: January 2021

Abstract
Breast cancer is the most common cancer in Polish women and the second leading cause of cancer deaths. Screening mammography is the only recognized method for early detection of malignant neoplasm and provides to reduction in cancer related deaths so far. The sensitivity of this examination is strongly influenced by the structure of the breast and is definitely lower for breasts of type 2 and 3 in accordance to American College of Radiology. That is why it is suggested that women younger than 35 years should be examined with ultrasound if necessary, and for women 35 years and older it is recommended to perform mammography, as the primary breast study. Ultrasound elastography is noninvasive imaging technique which can contribute to increase the sensitivity and specificity of recognition breast lesions. There are two main types of elastography: static and shear wave one. According to tissue stiffness, static elastography encodes lesions using a 5-point color scale – the Tsukuba University Score. Improvements in the interpretation of non-invasive examinations with using ultrasound elastography were discussed. It is considered that addition ultrasound elastography to ultrasound B-mode can play an important role in verification focal lesions in the breast.

The objectives of this research to determine the combination of the process of precipitation and adsorption in reducing the content of pollutant metals in the hazardous waste category B3 (hazardous toxic substances) produced at the Polinela Analysis Laboratory. The study was conducted in May to November 2019. The results obtained from 3 (three) times of sampling in May 2019 obtained a description of the characteristics of heavy metal content in wastewater in the form of Aluminum (Al) an average of 1.59 ppm, iron content ( Fe) an average of 9.73 ppm and Cadmium (Cd) an average of 0.022 ppm. From these results it can be seen that the wastewater containing Al and Fe has passed the threshold quality standard of waste water that is allowed to be discharged into water resource (PP No.82 of 2001), while the Cd content is still below the threshold. Furthermore, through the precipitation process with Ca (OH)2 0.8 M and adsorption using activated charcoal with contact time of 3 (three) hours the content of pollutants in wastewater can be reduced to 0.92 ppm for Al metals and 0.1 ppm for metals Fe, so that it is below the standard quality of waste water that is allowed to drain in water.
Keywords: adsorption, precipitation, quality standard

Предложена модель принятия решений в задачах фондового инвестирования как игра с природой с известными вероятностями состояний. Целью исследования является разработка новых принципов принятия решений в играх с природой и их применение для анализа статистических данных и выбора стратегий фондового инвестирования. В качестве оценки эффективности принимается математическое ожидание выигрыша инвестора, а в качестве оценки риска - среднеквадратическое отклонение. Эта двухкритериальная задача формализуется путем перевода оценки риска в ограничение. Научная новизна результатов исследования заключается в получении аналитического метода решения возникающей нелинейной задачи математического программирования и алгоритма поиска оптимальной смешанной стратегии. Приведен практический пример применения предложенных методов нахождения стратегий инвестирования на базе реальных статистических данных.
A decision-making model in stock investment problems is proposed as a game with nature with known state probabilities. The aim of the study is to develop new principles of decision-making in games with nature and their application for the analysis of statistical data and the choice of stock investment strategies. The mathematical expectation of the investor's payoff is taken as an assessment of efficiency, and the standard deviation as a risk assessment. This two-criteria problem is formalized by translating risk assessment into a constraint. The scientific novelty of the research results lies in obtaining the analytical method for solving an arising nonlinear problem of mathematical programming and the algorithm for finding the optimal mixed strategy. The practical example of the application of the proposed methods for finding investment strategies based on real statistical data is given.
