ANALYSIS OF STRENGTH CRITERIA IN THE DESIGN OF PRODUCTS FROM COMPOSITE MATERIALS
Authors: Dzierwa Andrzej , Stelmach Nataliia 
Published: July 2021

Technological progress gives rise to the continuous expansion of the class of structural materials and the improvement of their properties. The appearance of new materials is due to the natural desire to increase the efficiency of the structures under development. One of the most striking manifestations of progress in the development of materials, structures and technology is associated with the development and application of composite materials. Composites have a number of obvious advantages over other materials, in particular over metals. Such advantages are high specific strength and rigidity, high corrosion resistance, good ability to withstand alternating loads and others. It should be noted another, perhaps the most important feature of composites - is the ability to change the properties of the material in accordance with the purpose of the structure and the nature of its load during operation.
Under the influence of loads on the structure, its strength is estimated by the ultimate state of the materials of the structural elements. When a boundary state arises in a material, its transition to another mechanical state - elastic, plastic, or fracture state - occurs. This article aims to determine the optimal criterion for the strength of composite material that takes into account different values of ultimate stresses not only in different directions of the coordinate axes, but also to stretch and compress and further calculate the maximum allowable load for single-layer unidirectional composite material
During the research the main properties of composite materials, methods of manufacturing parts from composite material, their main properties and methods of destruction were considered. The characteristics of the strength criteria of composite materials are given, the most suitable for calculating the maximum value of the allowable load for a single-layer unidirectional composite material is determined. The proposed approach to the optimal design of elements of single-layer composite structures may be of interest to developers of numerous and analytical methods for solving problems of optimal design of more complex structures.

The utilization of steep lands by planting forestry and agricultural species can provide benefits from soil-water conservation and economic aspects. The combination of planting <em>Neolamarckia cadamba-Phaseolus vulgaris</em> and terrace systems can increase land use values, such as soil conservation, crop production, and farmers’ income. The aim of this study was to analyze silvicultural, hydro-orological, and economic aspects of a combination of forestry-agricultural crops<em> </em>(<em>N. cadamba – P. vulgaris</em>) and terrace systems on two slope classes. Two study plots were established on a steep gradient (25–40%) and a very steep gradient (&gt;40%). The results showed an annual increase in the average diameter and height of <em>N. cadamba</em> of 1.78 cm and 1.84 m, respectively on the steep slope, and 1.68 cm and 1.53 m, respectively on the very steep slope. The surface run off and erosion rate were lower on the steep ground compared to the very steep ground. Erosion hazard indices and levels on the plots in the steep slope and very steep slope were categorized as low and very low; meanwhile the erosion hazard class was I. The profit of <em>P. vulgaris cultivation </em>was IDR 9,360,000.00 ha<sup>–1</sup> per cropping season<sup> </sup>on steep slope and IDR 6,480,000.00 ha<sup>–1</sup> per cropping season on very steep slope. The planting of <em>P. vulgaris</em> as an intercropping plant to fill empty land in between <em>N. cadamba</em> can increase the economic value obtained from selling <em>P. vulgaris</em> in the short term until the leaves of the <em>N. cadamba</em> plant are linked. The combination of planting <em>N. cadamba–P. vulgaris</em> and terrace system on steep slopes is therefore more profitable not only from the economic perspective, but also in lowering runoff and potential erosion rates than on very steep lands.
ALGORITHMS AND SOFTWARE OF BUILDINGS INTERMITTENT THERMAL CONDITIONS OPTIMAL CONTROL
Authors: Tovazhnyanskyy Vladimir 
Published: July 2021

The actual problem of synthesizing the optimal control law for the intermittent heating mode of office buildings is considered, which consists in the programmed reduction of the room temperature during off-hours. The analysis of information sources showed the absence of sufficiently justified methods for solving the problem of optimizing the thermal processes of buildings, which provide comfortable conditions for the functioning of personnel, on the one hand, and save costs for buildings maintenance, on the other hand. The statement of the building thermal state optimal control problem is formulated, which contains a mathematical model of the process, a control goal, constraints on control actions and an integral quadratic quality criterion, including deviations of the room temperature from a given program and heat consumption. The limitation on the control action is taken into account by the method of penalty functions. As a mathematical model of the optimized thermal process, a two-dimensional controlled system of differential equations with constant coefficients is applied. The values of these coefficients are determined on the basis of building similarity criteria, which allows solving the optimization problem in a dimensionless form. The model includes a control action - the supplied heat flux, and a disturbing action - the ambient temperature, changing according to a given harmonious law. The numerical solution of the optimal control problem is implemented by the Chernous'ko method of successive approximations. A description of the user interface is given, as well as examples of the implementation of the thermal state optimal control. The proposed software allows on the stage of designing the heating system to obtain express assessments of various thermal modes of the building, and can also be used as computer support for automated individual heating points.
Keywords: intermittent heating mode, optimal control, mathematical model, control quality criterion, control constraints, penalty function, successive approximations, program interface, automated individual heating point.
USING METHODS AND TECHNOLOGIES OF RECOMMENDATION SYSTEMS FOR DYNAMIC SOFTWARE PRODUCT LINES CONFIGURATION
Authors: Gamzayev Rustam , Tkachuk Mykola 
Published: July 2021

Software product lines (SPL) dynamic configuring process could use methods for recommendation system (RS) elaboration. An overview and analysis of such methods was done in this paper. SPL represent a set of software systems that have common and variable functional components and use a set of paradigms and methods for development. In the classical static SPL the process of configuring performed before executing and performing in the operation environment (OE), in contrast dynamic software product lines performs after executing in the OE. Through the use of which it is possible to customize software solutions in accordance with the needs of end users. The following possible methods to build RS were considered: clustering, Markov decision-making process, matrix factorization. According to the review of the intelligent RS method development and researching of the functionalities of such systems in some open-source projects it was proposed to use N-dimensional context-dependent tensor factorization method and CARSkit tool system. Functional requirements and software architecture of the RS were developed. It allows to automatize software components configuration in the „Smart Home” (SH) systems that could be implemented with CARSkit software toolkit and algorithms implemented with programming language Python. This implementation allows to build a process for tracking changes in the external environment and transfer information to the SH system and, after analyzing the input data, process it in the RS to track changes in the context information. In the future research some additional quantitative experiments will be performed considering the specifics of the SH systems, additionally quantitative metrics will be used for efficiency assessment of the tensor factorization algorithms to predict the dynamic configurations of software components in these systems.
Keywords: recommendation system, software product line, variability, dynamic configuration, architecture.
