Open Data: A Stepchild in e-Estonia’s Data Management Strategy?
Authors: Tropp Elsa-Maria , Hoffmann Thomas , Chochia Archil
Published: June 2022

The availability of open data has increased dramatically, partly in reaction to several types of government agencies publishing their raw data. Access to and use of open data is not only essential for the development of public policy and delivery of various services, but it is also of eminent value for private (and often economic) purposes. To meet these demands, the availability of open data has increased dramatically both domestically and EU-wide. Nevertheless, it is still access to and use of personal data which is usually in the spotlight of public—and also legal—debates. Contributing to fill this gap, this paper analyses the significance of open data and the resulting challenges imposed by the widespread lack of specific open data policies. The paper also provides an overview of the existing systems used in Estonian governance to ensure access to open information, but also highlights the shortcomings, before it finally makes proposals on how to improve open data disclosure practices in Estonia.
Enhancing the Speed of the Learning Vector Quantization (LVQ) Algorithm by Adding Partial Distance Computation
Authors: AbuAlghanam Orieb , Adwan Omar , Al Shariah Mohammad A. , Qatawneh Mohammad
Published: June 2022

Learning Vector Quantization (LVQ) is one of the most widely used classification approaches. LVQ faces a problem as when the size of data grows large it becomes slower. In this paper, a modified version of LVQ, which is called PDLVQ is proposed to accelerate the traditional version. The proposed scheme aims to avoid unnecessary computations by applying an efficient Partial Distance (PD) computation strategy. Three different benchmark datasets are used in the experiments. The comparisons have been done between LVQ and PDLVQ in terms of runtime and in result, it turns out that PDLVQ shows better efficiency than LVQ. PDLVQ has achieved up to 37% efficiency in runtime compared to LVQ when the dimensions have increased. Also, the enhanced algorithm (PDLVQ) shows clear enhancement to decrease runtime when the size of dimensions, the number of clusters, or the size of data becomes increased compared with the traditional one which is LVQ.

Published: June 2022

The existence of a trade-off between embedding capacity and imperceptibility is a challenge to improve the quality of steganographic images. This research proposes to cross diagonal embedding Pixel Value Differencing (PVD) and Modulus Function (MF) techniques using edge area patterns to improve embedding capacity and imperceptibility simultaneously. At the same time still, maintain a good quality of security. By implementing them into 14 public datasets, the proposed techniques are proven to increase both capacity and imperceptibility. The cross diagonal embedding PVD is responsible for increasing the embedding capacity reaching an average value of 3.18 bits per pixel (bpp), and at the same time, the implementation of edge area block patterns-based embedding is a solution of improving imperceptibility toward an average value of PSNR above 40 dB and that of SSIM above 0.98. Aside from its success in increasing the embedding capacity and the imperceptibility, the proposed techniques remain resistant to RS attacks.
Basketball contract: applying the SIPRES method in the process of evaluating the negotiation template
Authors: Górecka Dorota , Gulak-Lipka Patrycja
Published: June 2022

In a negotiation process, knowing the preferences of the decision-maker and building a negotiation offer scoring system are very challenging tasks. There are many different methods that can be used to develop such a negotiation support tool, including, but not limited to, techniques based on the multiattribute utility theory (MAUT) or the outranking relation, for instance SAW, AHP or PROMETHEE II. In this paper we present the procedure of evaluating the negotiation template using an unconventional and inventive method called SIPRES, which combines the key elements of the revised Simos’ procedure and the ZAPROS method to elicit the negotiator’s preferences over some reference solutions. This transparent and easy to implement technique – thanks to the ZAPROS-like approach applied within it – allows the decision-makers to define their preferences in a simple manner, providing an effective method for analysing the trade-offs between the alternatives using selected reference alternatives only. Simultaneously, the revised Simos’ procedure, applied in the method, allows for determining the cardinal scores of the alternatives. Thus, sophisticated negotiation analyses can be carried out. As an illustrative example the problem of basketball contract negotiations is discussed.
Towards cognitive decision support: A model of behavioural assessment of multi-criteria methods
Authors: Roszkowska Ewa , Wachowicz Tomasz
Published: June 2022

The Negotiation Support Systems often implement multiple criteria decision aiding (MCDA) techniques for building a negotiation scoring system. Those formal models should meet the needs, motivations, expectations, and cognitive abilities of users. In this paper, we try to explore the effects of decision maker’s subjective perception of ease of use, time requirements, interface, preference representation, and efficiency of a particular MCDA method on the choice regarding the future use of this method. The multinomial logistic regression model is built and analysed. The analysis is based on data from online decision making experiments, where three MCDA methods were implemented, i.e. AHP, SMART, and TOPSIS. The study provides several interesting findings, concerning the behavioural aspects of multiple criteria decision aiding in software support systems. Most of the users recommended TOPSIS as the best one for supporting decisions in the future. This is a fast technique, for which we used an attractive graphical interface, suggesting that these factors play a crucial role in the users’ choices. However, the causative regression model showed that the user’s positive experience in using a particular method, i.e. its effectiveness in solving an exemplary numerical case, has the highest impact on the method’s choice for future use. The second most important factor is the adequacy in representing the user’s preferences by this method. We show, however, that the strengths of effects and their significance may vary across the methods. Understanding the decision maker’s evaluations of the MCDA techniques may help build a cognitive negotiation support system that satisfies the user’s expectations.
Impact of Remittances on Economic Growth: Empirical Evidence from South-East European Countries
Authors: Bucevska Vesna
Published: June 2022

South-East European (SEE) countries are experiencing high emigration, resulting in a significant increase in remittance inflows, exceeding FDI flows. Today the most important challenge facing SEE countries is how to grow at a higher speed to achieve faster economic convergence with the EU. The objective of the paper is to empirically examine the relevance of remittances as a factor of economic growth, using quarterly balanced panel data set of six SEE countries: Albania, Bosnia and Herzegovina, Croatia, Montenegro, the Republic of North Macedonia, and Serbia (SEE6) over 2008q1-2020q2. Panel regression with the fixed-effects model is employed to account for potential cross-section heterogeneity. This study provides original econometric evidence that remittances have a significant positive impact on economic growth in our panel of SEE6. Those results will be useful both to scholars and policymakers in the process of the creation of policies that will direct remittances into investments in the economy.

Thermal resistance of concrete airfield pavements
Authors: Nita Piotr , Linek Małgorzata , Poświata Adam
Published: June 2022

Concrete airfield pavements can frequently suffer from initially small and relatively shallow delamination of the subsurface concrete layer. It may be due to natural and forced temperature impact on the pavement. As a result of these impacts, thermal stresses and other phenomena are formed in the concrete slab. The significant phenomena are those related to the movement of water vapour in the slab cross-section and the associated processes leading to defects of the concrete structure. They are due to the complex interaction of various phenomena: thermal, humidity and strength that were considered damage stimulants.
Specifics of Power Losses in Power Lines Including Parallel Lines
Authors: Survilo J.
Published: June 2022

Reducing power losses is invested in the trend of combating climate warming. It is necessary to know what parameters of power transmission lines affect the losses in them. In short and medium lines with accounted lumped parameters, the role and influence of the line parameters on losses are visible. In the lines with distributed parameters, at least with one series parameter and one parallel parameter, the role played by them, computing losses in ordinary way as difference between power at line sending and receiving end, is hidden. This is pronounced when considering parallel lines. In two parallel lines the losses can be greater than in a single line. This may occur when the current at the end of the lines is less than the boundary value: the value when two parallel lines and a single line have the same losses. The longer the line and the higher the rated voltage, the stronger the effect. In view of this aspect, it is necessary to know the boundary current. This current can be determined in ordinary way by a series of calculations changing the load value. In some cases, boundary current is affected not only by modulus of the current at the end of the line but also by its angle. It is better to calculate the boundary current by a formula, while studying the role of each parameter.

Published: June 2022

Ventspils International Radio Astronomy Centre (Ventspils University of Applied Sciences) is implementing the scientific project “Complex Investigations of the Small Bodies in the Solar System” (lzp-2018/1-0401) related to the research of the small bodies in the Solar system (mainly, focusing on asteroids and comets) using methods of radio astronomy and signal processing. One of the research activities is weak hydroxyl (OH) radical observation in the radio range – single antenna observations using Irbene RT-32 radio telescope. To detect weak (0.1 Jy) OH masers of astronomical objects using radio methods, a research group in Ventspils adapted the Irbene RT-32 radio telescope working at 1665.402 and 1667.359 MHz frequencies. Spectral analysis using Fourier transform and continuous wavelet transform was applied to radio astronomical data from multiple observations related to weak OH maser detection. Multiple observation sessions of OH maser objects (R LMi, RU Ari, V524 Cas, OH 138.0+7.2, U Aur, etc) were carried out in 2020–2021.
Axial Flux Switching Permanent Magnet Alternator with External Magnetic Cores
Authors: Bezrukovs V. , Bezrukovs Vl. , Konuhova M. , Bezrukovs D. , Berzins A.
Published: June 2022

The article introduces the results of studying the magnetic field distribution in the alternator inductor with an axial arrangement of open magnetic cores (OMC) and external closure of magnetic fluxes. The study compares the efficiency of using magnetic fluxes from permanent magnets (PM) on the example of two model variants of inductors with OMC developed by the authors. The analysis of the density distribution of magnetic fluxes in OMC was carried out by 3D modelling of the magnetic field using EMWorks software. It has been shown that such generators can be manufactured using a waste-free technology for strip of OMC. This technology significantly reduces the production costs of OMC. By modelling the distribution of magnetic fluxes in the OMC of the inductor, the results of experimental studies and analysis of the created device show that the capacity of generator can be varied by changing its dimensions and the number of the toggle switches on the rotor. This allows the alternator to be adapted to the load requirements – power banks and bicycle electronics.
Influence of Parental Experience on Transformational Leadership Behaviour: A Test of Work–Family Enrichment of Male Managers from an Employee Perspective
Authors: Stellner Bernhard
Published: June 2022

Background: When a male leader becomes a father, changes in his transformational leadership behaviour occur due to shifted priorities, role expectations and resource transfer between domains. Work–life enrichment research acknowledges the positive overall effects of fatherhood on overall transformational leadership behaviours. Our quantitative study contributes to existing knowledge by analysing the perception of behavioural changes of leaders from the employees’ view. The results are matched with previous studies to assess differences of perception between leaders and employees.

Methods: Our research uses a granular, detailed definition of transformational leadership. Based on a sample of 139 respondents, we test the positive effects of fatherhood on leadership performance with Wilcoxon signed rank sum tests.

Results: 13 out of 15 transformational leadership behaviours improve significantly with fatherhood. We find that leaders and employees view change differently. Employees perceive improvement similarly in terms of direction, but it is less pronounced in terms of magnitude. Moreover, we find that well rated leaders tend to benefit the most from fatherhood, at least from the perspective of their employees. Males perceive higher levels of improvement than females, which we attribute to a gender empathy bias.

Conclusion: Our study confirms work–family enrichment theory and the positive effects of fatherhood on transformational leadership behaviour. Nevertheless, we show that not all involved parties perceive behavioural changes conformably.
The Interplay of Restaurant SMEs’ Entrepreneurial and Environmental Characteristics, Management of the Requisite Assets, and Operational Efficiency
Authors: Planinc Tanja , Kukanja Marko , Žnidaršič Anja
Published: June 2022

Background/Purpose: SMEs are subject to different factors in the business environments that influence their business performance. Considering the importance of restaurants’ environmental characteristics, entrepreneurs can also, through their entrepreneurial characteristics, influence SMEsʼ management of the requisite assets (MRA). Accordingly, this study examines the influence of restaurant SMEs’ entrepreneurial (self-efficacy, orientation, and demographics) and environmental (location, size, and competition) characteristics on MRA and, consequently, on SMEs’ operational efficiency.

Methods: Primary data relating to the environmental (location, size, and competition) and entrepreneurial (self-efficacy, orientation, and demographic) characteristics were obtained using a survey questionnaire, while the secondary data were obtained from SMEs’ official financial reports. The sample consists of 266 restaurant SMEs in the Republic of Slovenia. Efficiency was analysed using data envelopment analysis (DEA), and structural equation modelling (SEM) was used to test the research model.

Results: The results indicate that environmental characteristics have a much more significant impact on MRA than entrepreneurial characteristics. Entrepreneurial self-efficacy and most demographic characteristics (age, gender, education, and experience) proved not to influence significantly MRA and, consequently, SMEs’ operational efficiency.

Conclusion: SMEs’ external environment is generally not directly influenced by managerial decisions. Therefore, it is critical to strengthen the influence of the internal environment through an active development of entrepreneurial characteristics, which could result in a more effective MRA and higher efficiency. The conclusion provides suggestions for future research and valuable information for entrepreneurs, academia, and policymakers.
Bullying in Physical Education: Awareness of Physical Education Teachers
Authors: Sağin Ahmet Enes , Uğraş Sinan , Güllü Mehmet
Published: June 2022

This study investigates how physical education (PE) teachers make sense of peer bullying, which types of behaviors they associate with peer bullying, their opinions about these behaviors, and methods for preventing bullying. The study group consisted of 18 PE teachers. The interview technique was used as a qualitative research method in the study. The data obtained after one-on-one interviews were analyzed through content analysis. According to the data obtained, PE teachers are the most important variable in the decrease or increase of peer bullying in classes. However, PE classes provide a suitable environment for the emergence of peer bullying. Additionally, bullying caused by the individual characteristics of students and environmental reasons can increase in schools, and there are generally no collective intervention programs within schools to prevent it. According to the teachers’ opinions, some of the important results are that students who are exposed to bullying experience the same fear every week in PE lessons, and although it is known that the majority of them do not want to participate in the activity in order to avoid being bullied, no solution can be found.

The paper focuses on five activation areas: adjustment of unemployment benefit eligibility, improving employment services, participation in active labour market policies, monitoring and sanctions. The review lists several recommendations Slovenia should apply to activate unemployment benefit recipients, including introducing more demanding job search requirements and increased monitoring of the compliance with these requirements, introducing compulsory participation in active labour market programs, checking the consistency and effectiveness of the current profiling system, and strengthening the ex-ante effect of sanctions.
The firm-specific and macroeconomic determinants of the financial structure of construction companies in selected European countries
Authors: Růčková Petra , Škuláňová Nicole
Published: June 2022

This research builds on previous studies in the field of financial structure and develops knowledge for the construction industry in eight selected countries in Central and Eastern Europe – Visegrád Group, Austria, Bulgaria, Slovenia, and Romania. The aim of the research is to examine the influence of profitability, asset structure, the GDP growth rate and the reference interest rate on the level of total, long-term and short-term debt of companies. The research period is from 2009 to 2018. The main conclusion of the research is the finding that the amount of debt of selected construction companies is most affected by the determinants of the external environment – the development of the economy and the reference interest rate. This conclusion applies regardless of the size of the companies. The direction of the resulting impact differs, as each of the economies underwent a different economic development during the period under review. The interest rate negatively affected the amount of debt of Polish, Romanian and Hungarian companies, given the higher interest rates in these economies; the remaining companies have a positive impact. The impact of the GDP growth rate on the amount of debt is mainly negative for Romanian companies regardless of size, medium-sized Polish and Austrian companies, and large Czech companies; a positive effect was found for the remaining companies. Economies have grown for most of the period under review, and negative impacts may mean taking advantage of profits, which usually grow during periods of prosperity and are a cheap source of funding. This does not necessarily mean economic problems and, as a result, declining debt due to the unavailability of debt financing.
Feasibility Study for a Fuel Cell-Powered Unmanned Aerial Vehicle with a 75 Kg Payload
Authors: Desantes José M. , Novella Ricardo , García-Cuevas Luis M. , Lopez-Juarez Marcos
Published: June 2022

Among the possible electric powerplants currently driving low-payload UAVs (up to around 10 kg of payload), batteries offer certain clear benefits, but for medium-payload operation such as aerotaxis and heavy-cargo transportation UAVs, battery capacity requirements restrict their usage due to high weight and volume. In light of this situation, fuel cell (FC) systems (FCS) offer clear benefits over batteries for the medium-payload UAV segment (> 50 kg). Nevertheless, studies regarding the application of FCS powerplants to this UAV segment are limited and the in-flight performance has not been clearly analysed. In order to address this knowledge gap, a feasibility analysis of these particular applications powered by FCS is performed in this study. A validated FC stack model (40 kW of maximum power) was integrated into a balance of plant to conform an FCS. As a novelty, the management of the FCS was optimized to maximize the FCS efficiency at different altitudes up to 12500 ft, so that the operation always implies the lowest H2 consumption regardless of the altitude. In parallel, an UAV numerical model was developed based on the ATLANTE vehicle and characterized by calculating the aerodynamic coefficients through CFD simulations. Then, both models were integrated into a 0D-1D modelling platform together with an energy management strategy optimizer algorithm and a suitable propeller model. With the preliminary results obtained from the FCS and UAV models, it was possible to ascertain the range and endurance of the vehicle. As a result, it was concluded that the combination of both technologies could offer a range over 600 km and an endurance over 5 h. Finally, with the integrated UAV-FCS model, a flight profile describing a medium altitude, medium endurance mission was designed and used to analyse the viability of FC-powered UAV. The results showed how UAVs powered by FCS are viable for the considered aircraft segment, providing competitive values of specific range and endurance.
Emotion-Related Language Choice theory in the cross-fire: Evidence from Mexican-American bilinguals
Authors: Pawliszko Judyta
Published: June 2022

The present study aims to determine the overall language choices that shape emotion-related language preference among bilingual communities. The author also seeks to answer the question of whether those choices are affected by norms or emotional spontaneity. Since the study yields only a slight preference for the second language, it may not necessarily lead to concluding any linguistic system to be more dominant than the other. Yet, the research proves not only that greater emotional weight of the situation results in a greater impact on the emotion-related language choice, but it also suggests that the main determiner of the language choice within bilinguals is not necessarily the different emotive power of both linguistic systems, but sociocultural norms.

Published: June 2022

For all administrative activities to be purposeful and effective, they must be governed by some fundamental rules and regulations that help the administrator to determine what to do in a given problem situation. It is these fundamental rules and regulations that are normally referred to as “principles of administration”. For organization to achieve its set goals and objectives, administrators are required not only to deal with the traditional concerns of administration and management, policy development and service delivery but increasingly, the job of administrators in contemporary times will be that of fostering citizenship and identifying, creating and managing public values by applying administrative principles and processes. Therefore, an overview of administrative principles, processes and practice is the objective of this paper. This paper adopted qualitative research design and draws its argument basically from secondary data which include journal articles, textbooks and internet sources. Finally, the paper concludes that organization will grow from strength to strength if administrators will stick strictly to the general goals and objectives of the organization through the implementation of the 29 administrative principles

Published: June 2022

Hyperpolarized (i.e., polarized far beyond the thermal equilibrium) nuclear spins can result in radiofrequency amplification by stimulated emission of radiation (RASER) effect. Here, we show the utility of RASER to amplify NMR signals of solute and solvent molecules in the liquid state. Specifically, parahydrogen-induced RASER was used to spontaneously enhance nuclear spin polarization of protons and heteronuclei (here 19F and 31P) in a wide range of molecules. The magnitude of the effect correlates with the T1 relaxation time of the target nuclear spins. A series of control experiments validates the through-space dipolar mechanism of RASER-assisted polarization transfer between parahydrogen-polarized compound and to-be-hyperpolarized nuclei of the target molecule. Frequency-selective saturation of RASER-active resonances was used to control the RASER and the amplitude of spontaneous polarization transfer. Spin dynamics simulations support our experimental RASER studies.
Tetrazine-Triggered Bioorthogonal Cleavage of trans-Cyclooctene-Caged Phenols Using a Minimal Self-Immolative Linker Strategy
Authors: Keppel Patrick , Sohr Barbara , Kuba Walter , Skrinjar Philipp , Carlson Jonathan , Mikula Hannes
Published: June 2022

Bond-cleavage reactions triggered by bioorthogonal tetrazine ligation have emerged as strategies to chemically control the function of (bio)molecules and achieve activation of prodrugs in living systems. While most of these approaches make use of caged amines, current methods for the release of phenols are limited by unfavorable reaction kinetics or insufficient stability of the Tz-responsive reactants. To address this issue, we have implemented a self-immolative linker that enables the connection of cleavable trans-cyclooctenes (TCO) and phenols via carbamate linkages. Based on detailed investigation of the reaction mechanism with several Tz, revealing up to 96% elimination after 2 hours, we have developed a TCO-caged prodrug with 700-fold reduced cytotoxicity compared to the parent drug and achieved efficient in situ activation upon Tz/TCO click-to-release.

The Teaching of Initial Multiplication Concepts and Skills in Croatian Textbooks
Authors: Trupčević Goran , Valent Anđa
Published: June 2022

The goal of this paper is to describe the teaching of initial multiplication concepts and skills, up to the multiplication table, in the Croatian educational system. As Stiegler and Hiebert (1999) concluded, teaching is a complex system rooted in a cultural script of a given society. To describe it without ignoring certain features of it that appear to be self-evident to an insider, it is necessary to step out of this cultural frame. For that reason, we study the teaching of initial multiplication in Croatia by comparing Croatian mathematical textbooks with textbooks from Singapore, Japan, and England. For the textbook analysis, we adapt the framework of Charalambous, Delaney, Hsu, and Mesa that examines a textbook as an environment for the construction of knowledge of a single mathematical concept. The analysis provides evidence that practice and automation are at the centre of the initial learning of multiplication in Croatia. The meaning of multiplication usually is not clear, and pupils are not provided additional tools for developing understanding, nor they are encouraged to use different calculation strategies in a flexible manner. The study also indicates that Croatian textbooks present mathematics as a practice that is closed and pre-given, restricted to the one and the only right way through it.
Sujeto, pensamiento y lenguaje en el primer Wittgenstein
Authors: Defez Martin Antoni
Published: June 2022

En contra de las interpretaciones psicologistas del Tractatus, en este escrito se presentan la normatividad y la intencionalidad lingüísticas como expresión de la propia acción lingüística, estando la normatividad fijada por el propio lenguaje y siendo su intencionalidad expresión de la actividad no empírica del sujeto metafísico.
Jámblico y la mistagogía de la mirada: hacia una ontología de la imagen
Authors: Benito Torres Jorge
Published: June 2022

La recepción del neoplatonismo en la filosofía contemporánea ha abierto diversas sendas del pensar que, a su modo, han llegado a los núcleos duros de esta corriente. Así, mientras la hermenéutica ha señalado el hito filosófico que supone la metafísica neoplatónica de la imagen, otros autores han considerado que los máximos exponentes de esta metafísica beben, directamente, de la fuente del irracionalismo. La exégesis de la obra de Jámblico se encuentra en esta misma encrucijada. En el De Mysteriis, la noción de imagen (εἰκὼν) hilvana toda una red de conceptos que configuran un cosmos indudablemente original. Tomando esta noción como guía, indagaremos en la ontología propuesta por Jámblico para contemplar el quehacer filosófico como una suerte de mistagogía racional o una iniciación filosófica en los misterios de lo divino. Vinculada a esta ontología encontraremos una exégesis de las potencias del alma y de sus modos de comprensión y conocimientos, que sin duda alguna puede ser comprendida como una determinada hermenéutica de sí. Esta lectura, a su vez, hará viable conectar los puntos cardinales de la filosofía de Jámblico con la tradición platónica, lo que nos permitirá mostrar el fuerte criticismo del racionalismo neoplatónico.
Expanding the Clinical and Genetic Spectrum of Caveolinopathy in Korea

Purpose: Caveolinopathy is a disease caused by caveolin-3 (CAV3) mutations that shows a wide clinical spectrum, including isolated hyperCKemia and limb-girdle muscular dystrophy. While recent advances in next-generation sequencing (NGS) have enabled earlier diagnosis of this disease, it remains difficult to predict the clinical course of each patient.Methods: This study summarizes the clinical presentations of 13 genetically confirmed caveolinopathy patients in four Korean families. Genetic diagnosis was performed using NGS technologies for probands and Sanger sequencing for the other family members.Results: Four coding mutations were found (p.Val103_Val104del, p.Asp28Glu, p.Pro105Leu, and p.Arg27Gln), and each family showed autosomal dominant inheritance. While all 13 cases had hyperCKemia, only five of them showed some myopathic features including ankle contracture, calf hypertrophy, exercise intolerance, and muscle cramping. This high proportion of asymptomatic cases suggests both that these mutations may be associated with a mild phenotype and that caveolinopathy may be an underdiagnosed disease.Conclusion: This study extends our understanding of caveolinopathy; in particular, the findings suggest the need to consider caveolinopathy in patients with incidental findings of CK elevation. NGS may be a useful method in the differential diagnosis of such cases.
MICROMETRY OF CYLINDER LINERS OF YAMZ ENGINES

The most important part that limits the engine life is the cylinder liner. Before fault finding in the cylinder liners, it is necessary to carry out the micrometry of their surface to identify the areas of greatest and least wear. For carrying out the micrometry and testing it on new and worn cylinder liners, 40 cylinder liners of YaMZ engines were used. The working surface of the cylinder liners was controlled by the inner diameter, which was measured in eight sections and two planes. The micrometry was carried out with an indicating hole gauge with a digital head of increased accuracy with a sensitivity of 0.001 mm; ten new cylinder liners met the technical requirements. The micrometry of thirty cylinder liners showed that the greatest wear was 253 μm in the connecting rod oscillation plane and 189 μm in the perpendicular plane. It was found that liner micrometry should be particularly thoroughly carried out at the top of the cylinder liners. The greatest wear occurs at the top piston ring stop at the start of the expansion stroke, with more intensive wear in the connecting rod oscillation plane due to the normal force. The uppermost part of the cylinder liners is the wear-free liner flange, the diameter of which indicates the original dimensions of the liner bore. However, it must also be measured due to the effects of high temperatures, changes in the crystal pattern of the material, oxidation and the presence of combustion products in the form of carbon deposits. The lower part of the cylinder liner is subject to wear due to the friction of the piston skirt against its surface. However, due to the lower temperature, the better lubrication, the much larger contact surface and the correspondingly lower pressure, increased wear here can only occur if there are misalignments in the crank mechanism: the misaligned crankshaft axle or the bent connecting rod.
