Quality, waste and cost considerations in architectural building design management

This article presents the results of a comprehensive research on the organizational and technological reliability of the rail grinding process. It includes an analysis of the current fleet of rail grinding trains, the regulatory framework, operational planning, and quality assessment revealed a key problem: the low organizational and technological reliability of the process. This leads to poor work quality, increased operating costs, reduced traffic safety, and the risk of delays in completing the work. The methodology is based on detailed mapping of production operations, personnel workload analysis, and the use of FMEA analysis for expert process evaluation. Mapping of production operations in various sections was carried out with the involvement of an expert group that included representatives of operating teams, service organizations, quality controllers, and equipment developers. During the survey of three trains, a number of design, system, and technological issues were identified. The time analysis showed the actual duration of grinding, the ratio of auxiliary operations, working time, and team workload. To quantify the reliability of the grinding process, an FMEA analysis was conducted with the involvement of experts. The risks were ranked according to their priority. The constructed risk matrix identified ‘critical’ operations. Simulation modeling was performed, revealing significant risks of traffic safety violations and ‘window’ discipline. Based on the operation programs of the rail grinding process, a network model of grinding was developed, and a machine experiment consisting of 1,000 repetitions was conducted. The research results demonstrated the need to revise organizational and technological solutions to improve the reliability and efficiency of the rail grinding process. The proposed set of measures will improve the reliability, quality, and efficiency of the rail grinding process.

The article describes the effective directions of the teaching process and mental development of a junior high school student. It says that the opinions of domestic and foreign scientists should be analyzed and priority areas should be taken into account. In psychological research, the initial methodological conditions used during the education of junior school students and ways of their psychological clarification are provided. The peculiarity of primary school is that teaching depends more on the teacher than on the school curriculum. Although there are a lot of requirements and teaching tasks in the curriculum, a competent teacher tries to minimize themand explain themto the student in a concise manner.The psychological study of education is consideredto be the systematization and analysis of the most rational ways and methods of managing the educational process at the present time. The problem of increasing the efficiency of the educational process due to the structural and systematic analysis of the educational material attracts the attention of scientists.In the educational process, it is no longer enough to acquire simple skills such as reading, writing, counting, and calculating. The formation of these skills includes solving broader and more important tasks:First of all, to introduce children to subject education in the logic of scientific knowledge, to reveal to them the basic and fundamental properties of the studied sphere of existence that make up the content of this science. Thus, the acquisition of reading skills becomes the study of language as a means of communication and thinking, and simple counting skills -the study of numerical relationships.Secondly, the formation of learning activities in children with their own tasks and methods. At the current stage of development of our society, a person should be engaged in educational activities throughout his life. This is the second "specialty" of each person, the ability to realize it depends mainly on the progress in the chosen profession.Thirdly, it is necessary to use all opportunities of the primary education period for the formation of learning motives and intellectual development of children.An urgent problem in solving the problem of increasing the efficiency and quality of the educational process is the activation of schoolchildren's learning. Its special importance is that teaching, being a reflexive and transformative activity, is aimed not only at the reception and memorization of the learning material but also at the formation ofthe student's attitude towards the cognitive activity itself. The transformative nature of the activity is always related to the activity of the subject.

The quality of the educational process is considered here as a complex unity of substantive, procedural and effective components that are necessary and sufficient for achieving complex (pedagogical and socio-cultural) goals relevant to a particular stage of development of the national education system. The key parameters of the criteria for assessing the quality of the educational process of general secondary education include social and personal significance, realism, transparency and accessibility for assessment subjects, instrumentality and adaptability, adaptability, variable mobility, etc. Actually, the assessment of the quality of the educational process is considered as a multisubject, multidirectional and multidimensional activity.In accordance with this, a criterial basis is proposed for assessing the quality of the educational process of general secondary education.The system of criteria includes the positions of the educational itself (they are connected with the education, the formation of student subject and metasubject competences, preparation for professional self-determination, etc.) and sociocultural (associated with the fulfillment of the sociocultural order of society and the state, satisfaction of their expectations, including deferred).The proposed criteria differ in the nature of long-range actions: some of them are aimed at assessing the immediate, current and medium-term results of educational activities, while others are aimed at assessing the degree of achievement of strategic educational goals. This article focuses primarily on criteria of the first type; they are considered as indicators focused on assessing the quality of the educational process of general secondary education as a multi-vector activity for the provision of a set of relevant educational services. It is important to understand these educational services precisely as a complex, where the actual training and upbringing is combined with various types of sociocultural activity, the integral effect in the end should be the formation of a graduate ofthe school readiness for professional and personal self-determination, as well as an adequate level of sociocultural adaptability.The system of proposed integral evaluation criteria is aimed at the coordinated analysis of the conditions, the actual organization and implementation process, as well as the effectiveness and efficiency of the educational process. Along with the justification of the significance and novelty of a criterion for the contemporary system of education quality assessment, the most appropriatecontexts of its use by different subjects of evaluation (participants of the educational process) are determined.

Optimizing neurosurgery clinic operations: a comparative study of interventions in Finland's public healthcare system.

The aim of this study is to investigate the wear mechanism of diamond grains at different cutting speeds and determine the optimal conditions to improve the efficiency of granite processing using diamond saw blades. The study considers both cutting speed parameters and feed rate to establish optimal operating conditions that achieve high productivity with minimal tool wear and an extended tool lifespan. The research was conducted using a specialized edging machine equipped with a 600 mm diamond saw blade. The object of study was Kapustinsky granite, characterized by high hardness and a complex microstructure. During the experiment, the wear of diamond grains was measured using electron microscopy after each cutting stage. Two main feed rate options were used: 1,2 mm/rev and 1,6 mm/rev. The cutting speed varied between 20 and 45 m/s. The results of the study showed that the optimal cutting speed for achieving balanced cutting efficiency and minimal diamond grain wear is 30–35 m/s. At these speeds, effective grain renewal is ensured, maintaining the cutting ability of the tool at a sufficient level. Higher speeds (above 35 m/s) lead to intense destruction of diamond grains, an increase in the proportion of cracked and worn grains, and a decrease in productivity and tool lifespan. Additionally, speeds below 25 m/s result in insufficient grain renewal, which also reduces cutting efficiency. Based on the results, the optimal cutting speed for working with Kapustinsky granite was determined to be 30–35 m/s at a feed rate of 1,2 mm/rev. Using these conditions ensures stable grain renewal, reduces tool wear, and improves processing efficiency. Practical recommendations derived from this study allow for a 15 % reduction in tool replacement costs, improve cutting process efficiency, and extend the lifespan of diamond saw blades by 20–25 %. This will help reduce overall production costs and improve the competitiveness of the stone processing industry. The scientific novelty of this study lies in analyzing the impact of different cutting speeds on the wear pattern of diamond grains and determining optimal operating conditions to reduce energy consumption and improve the productivity of hard material processing. The recommended regimes can be applied to enhance technological processes in the stone processing industry, which is an important factor for improving economic efficiency and the quality of natural stone processing. Keywords: diamond grains, cutting speed, wear, cutting efficiency, granite processing, diamond tools, optimal conditions, stone processing industry.

In this paper we study the influence of the processing wavelength on process efficiency and quality at picosecond microdrilling in steel. Possible optical setups for utilizing the second harmonic will be presented, and the influence of wavelength on the drilling rate will be discussed. The potential of helical drilling with the second harmonic in 1 mm thick CrNi-steel will be investigated with regard to process efficiency and hole quality. An analysis will be given of the role of particle-ignited atmospheric plasma and the relation between isophote contour and hole morphology. Our study reveals that a substantial enhancement of both precision and productivity can be achieved by using frequency-doubled instead of infrared radiation. It is shown that plasma ablation and melt production can be minimized by drilling with the second harmonic.

This study tackles the challenges of inconsistent weld quality and limited real-time monitoring in Tungsten Inert Gas (TIG) welding by developing a digital twin for the process. The primary objective is to enhance process efficiency and quality control by creating a high-fidelity virtual model of TIG welding that enables real-time monitoring and control. To achieve this, the study employs Desirability Function Analysis (DFA) to optimize multiple quality characteristics. The methodology integrates advanced sensors and IoT technologies to gather real-time data on critical welding parameters such as current, voltage, travel speed, and gas flow rate. This data is used to create a simulation model that accurately replicates the physical welding process. The experiments are conducted using digital twin on SS304 thin which is widely used in industrial applications. By applying DFA, the study converts multiple quality characteristics into a single composite desirability score, offering a quantitative assessment of process efficiency and output quality. The experimental results demonstrate the digital twin’s ability to accurately predict and control welding outcomes, significantly improving productivity and quality control. This research highlights the transformative potential of digital twin technology in TIG welding, paving the way for smarter, data-driven decision-making in industrial settings.
