Practical Role of Philosophy in Sport: Case of Philosophical Consultation
Authors: Mareš Lukáš 
Published: June 2019

Abstract
The process of philosophical questioning has the power to form not only our way of thinking, but also the way we live. Both my sporting and academic career have made me think about the importance of asking good questions and undergoing the process of answering them. I decided to create a profession of philosophical consultation in sport which works with athletes and coaches of various ages. Consultants and athletes (clients) engage in a dialogue about important and interesting questions/topics in client’s life. This dialogical process is called philosophical consultation. It focuses on critical evaluation and development of client’s thinking, self-cognition, and attitudes/worldviews. Philosophical consultation helps athletes and coaches to look for their identity and achieve better self-awareness. It can be argued that consultation offers what Patočka calls the “care of the soul” (epimeleia peri tês psychês) or what Foucault calls the “care of the self” (epimeleia heautou), which are based on Socrates’ kind of philosophizing. It helps to achieve ancient ideals of kalokagathia and gnôthi seauton. The potential of using philosophy in sport hasn’t been fully discovered. Philosophical consultation is presented as a process of self-cognition and inner development. It has the potential to influence the care for well-being of athletes and coaches.
I aim to explore the practical role of philosophy in sport. I will present possible connections between philosophy and sport and the historical predecessors of the concept of philosophical consultancy in sport. As well, we will discuss what philosophical consultancy is, how philosophical consultant works, and finally what are the challenges in bringing philosophical consultation into sport. Methods that are used in this interdisciplinary article are critical textual analysis, description, and interpretation of data.
The Justice of the Grand Slam Tennis Tournaments on the Basis of Draw, Competition Format System and Final Result: a Case Study of the US Open 2017 Men’s Singles Tournament
Authors: Zimányi Róbert G. , Géczi Gábor 
Published: June 2019

Abstract
The tennis Grand Slam tournaments play a key role among the major sport events. Sport has also got a social interest to strive for justice. Is the main draw always fair? Is the competition format system right? Overall: can we achieve a just final result? When answering these questions, we need to focus on the telos of the sport event. Present study shows the relating theories of justice and examines them in connection with the US Open: from the evolutionist conception, through Aristotle’s excellence-based justice theory, to egalitarianism, meritocracy, equity and it also analyses some issues around positive discrimination. The study examines the justice theories of the US Open 2017 Men’s Singles Tournament’s with special focus on the draw, the competition format system and the final result. An important point: we can only talk about justice if it is consistent with the telos of the event – this is an exclusion criterion. In addition to the systematic processing of justice theories, the research is based on the International Tennis Federation’s (ITF) official documents and on the case study: the official competition regulation and final result of the US Open 2017 Tournament. As an outcome of the research, we can conclude that several theories of justice appear in accordance with the telos of the US Open 2017 Tournament. Each element, namely the draw, the competition format system and the final result can be fair, however, they all depend on the applied theory of justice. Which theories should be applied in certain cases and why? The research also confirms that certain theories of justice do not match the telos of the US Open Grand Slam Tournament. These theories cannot be applied in certain cases. For future search areas we can examine other justice theories, or other related tennis event’s justice.

Abstract

Introduction: Brain rate is parameter correlated to brain electric and metabolic activity.

Aim: The aim of this study was to analyze the results obtained for brain rate parameter as an indicator for general mental arousal in anxious patients and to compare them with results of healthy young people matched in age and gender, as well as with anorectic and hyperactive children.

Material and Methods: The diagnosis for all examinees was made according two statistic manuals (DMSIV- R and ICD-10), medical history, neuropsychological assessment, biochemical analysis and QEEG. In this study we examined the spectra power of the brain waves through quantified EEG (QEEG). The obtained results were exported to brain rate software and then calculated for each region separately. The QEEG spectra power data and the brain rate data were analyzed using Statistica software.

Results: According to sagittal and lateral topography maximal values of brain rate parameter were obtained in group of healthy individuals and in group of anorectic patients. The lowest results were obtained in group of hyperactive children for all three regions.

Conclusions: The general conclusion will be that pathological conditions in childhood, analyzed in this research, can be defined as conditions of hypoarausal and this can be specific sign of brain dysfunction.

Abstract

Introduction: The aim of the study was to compare the results of two human papillomavirus (HPV) diagnostic techniques: human papillomavirus deoxyribonucleic acid (HPV DNA) testing and human papillomavirus E6/E7 messenger ribonucleic acid (HPV E6/E7 mRNA) testing in women with squamous cell abnormalities of the uterine cervix.

Material and Methods: Comparative prospective study, conducted in the period from January 2016 to June 2017 of 128 sexually active women, age groups of 20 to 59 years (40.50 ± 10.85) with squamous cell abnormalities on the cervical cytology. All patients were subject to: HPV DNA testing, HPV E6/E7 mRNA testing and colposcopic cervical biopsy with endocervical curettage for histopathologycal analysis. HPV DNA testing was done using multiplex polymerase chain reaction (PCR) and reverse hybridization methods. HPV E6/E7 mRNA testing was done using real-time PCR method.

Results: Data analysis showed an association between the results of HPV DNA testing and HPV E6/E7 mRNA testing (p˂0.0001). The concordance between the results of both tests was moderate (55.47%). The results show that HPV E6/E7 mRNA testing had a higer specificity 88.89% and positive predictive value (PPV) 93.59% for HSIL + invasive squamous cell carcinoma compared to HPV DNA testing that had specificity of 55.56% and PPV 84.61%, respectively.

Conclusion: The results of our study suggested that HPV E6/E7 mRNA testing is more specific and has a higher positive predictive value than HPV DNA testing and that viral oncoproteins E6 and E7 are superior biomarkers for the detection of high-risk HPV-associated squamous intraepithelial lesions of the uterine cervix.

Published: June 2019

Abstract
The study of the nature of distribution of natural radioelements in Ilesha and its environs with its geological structure has been studied using aeroradiometric data. Aeromagnetic data have also been subjected to three automated gradient techniques to delineate the sub-surface structure of the study area. From the study, it can be found that maximum values of “eU” (ppm) and “eTh” (ppm) fall within the branded gneiss, whereas the maximum value of K (%) falls within porphyritic granite regions. eTh had the highest radioactive content. The environmental dose rate of Ilesha was between 0.1817 and 3.9296 msv/yr. Although there were extreme values, but the mean dose rate was 0.522 ± 0.310 msv/yr (within acceptable safe limit of 1.0 msv/yr). eU/K, eU/eTh and eTh/K ratios were analysed for enrichment or depletion of radioisotopes. eU/eTh >1 showed uranium depletion, while eTh >2 showed eTh enrichment. The magnetic intensity values ranged from -79.41 to 140.93 nT. The horizontal gradient method (HGM) and analytic signal amplitude (ASA) revealed that depth to magnetic sources ranged from 0.478 to 4.112 km and 0.348 to 2.551 km, respectively, whereas local wavenumber (LWN) depth ranged from 0.478 to 5.48 km, which overestimated those compared using HGM and ASA functions. The apparent susceptibility ranged from -0.00325 to 0.00323 SI, showing that ferromagnetic and diamagnetic mineral ranges control apparent susceptibility in Ilesha.

Authors: Bodzás Sándor 
Published: June 2019

Abstract
The spur gear is widely used in many types of machines and appliances that is why the research of the connection analysis of them (Tooth Contact Analysis, TCA) is very important because of the development of these gears. The TCA analysis is a complex task because the mathematical description, the CAD modelling process, the overall designing process, the manufacturing process of the gears and the definition of the mechanical parameters have to be known. After the gear designing process the gear pairs have to be analysed by TCA method to determine the typical dimension of the mechanical parameters in case of given load. Knowing of the result we can reason for the appropriate gear geometry of the given construction and working conditions.

Abstract
In 21st century, it has been observed that Wire Cut Electrical Discharge Machining (WEDM) has evolved as one of the most important non-traditional machining process. The popularity and its success lies because of its uniqueness towards producing different components which are very difficult to machine like titanium, tungsten carbide, Inconel materials etc and provides a platform in producing intricate complex shape which in many cases become impossible to machine by traditional machining methods. Pure sintered titanium bears very high specific strength, abrasion and corrosion resistances and thus machining this type of materials by conventional techniques becomes very difficult though this material finds immense applications in bio-plant and aerospace components. In the present work, WEDM on pure sintered titanium is studied. The different input parameters of WEDM like, pulse on time, pulse off time, wire tension and wire feed have been varied to investigate the output response like MRR, Surface Roughness (Ra), Kerf Width and Over Cut. A response surface methodology (4 factors 3 level) design of experiment (DOE) has been applied in this context to examine the machining ability of pure sintered titanium and results are found to be satisfactory and verified by confirmatory test. The machining parameters like pulse on time, pulse off time, wire tension and wire feed shows immense effect on the output responses and present study provide an optimal conditions of these input parameters to get the best output responses through RSM

Published: June 2019

Abstract
The processes of supplying natural gas are accompanied by significant losses. In this regard, the complex problem of minimizing losses and improving the efficiency of energy use is very relevant. Steel pipelines for transportation of oil and gas often cross the tracks or are located parallel to the lines of electric power transmission lines of alternating current. Most dangerous from the corrosive point of view of the combination of the chemical composition of the soil electrolyte and the vagal current density were established.

Published: June 2019

Abstract
A wear proof layer was obtained by applying vibration with a frequency of 100 Hz and amplitude of 0; 70; 300 μm to the cored wire of Fe-Cr-B-C doping system during welding. It was shown that horizontal vibration affects the grinding process of boride inclusions: their average diameter reduces from 175 to 5 μm, and the amount of (FeCr)2B plastic phases increases during the redistribution of phases. Wear resistance of the metal, which was deposited using horizontal vibration with an amplitude of 300 μm, increases by 2.3-2.5 times due to wear with the fixed and unfixed abrasive material, and by 2.8 times due to wear under impact loads. For restoration and strengthening of large-size parts, it is proposed to add Al-Mg powder (Al = 47 - 53 %, Mg = 53-47% wt. %) to the CW charge to increase wear resistance of the deposited metal of the Fe-Cr-B-C system. This contributes to the dispersion of the boride inclusions, the average diameter of which decreases from 70 to 5 μm. In the structure of the deposited metal of the Fe-Cr-B-C system, inclusions of the complex alloyed nitrides are extricated with an average size less than 1.0 μm. As a result, the average value of microhardness increases from 700 to 900 HV. Wear resistance of the deposited metal increases by 1.5 times due to wear with the fixed and unfixed abrasive material, and by 2.0 times due to wear under impact loads.
A Paradigm for the Analysis of Preloaded Bolted Joints
Authors: Welch Michael 
Published: June 2019

Abstract
The purpose of this paper is to present a paradigm, or guide, to the analysis of preloaded bolted joints made using multiple bolts. Classical analysis methods are applied to the interaction of the joint elements subjected to combinations of both in-plane and out-of-plane loads and moments. The distribution of the external loads and moments within the preloaded joint is determined in relationship to individual bolts. An analysis of loads and stresses in individual bolts and dowels along with flange bending and thread shear in tapped or threaded holes is developed. The article brings together a number of concepts and links them into a practical design analysis process that is applicable for many cases of preloaded bolted joints and are adequate to demonstrate the structural integrity of each element of the joint. Interpretation of results, within the context of design standards, is provided. In some cases finite element methods may be more appropriate, and the methods discussed can be used in the validation process.

Abstract
The article describes the life cycle of a training project in a research and development unit, from setting the training target, through analyzing the needs of the group, establishing workshops’ programs and logistics, up to the evaluation and implementation support. The role of human capital has been presented in the article, thus the need for training organization has been demonstrated to improve quality of work. The article also describes characteristics of the training market, defining types of projects addressed to representatives of the most often trained groups in the research and development unit, like professionals, managers and research workers. Methods and tools aiding the training system analysis and monitoring have also been introduced in the text with a goal to reflect customer, employer, and trainee satisfaction. A process of raising qualifications of employees was described at the Institute of Aviation. It has been found that internal trainings from the subject matter of “project management” are the best solution for research and development centers.
The Influence of the Fastener Hole Preparation Method on the Fastener Pull-Through Process in a Carbon Composite
Authors: Karny Maciej 
Published: June 2019

Abstract
This article studies the pull-through resistance of a titanium carbon fibre-epoxy resin laminate fastener. Coupons with fastener holes made with different methods were compared – drilled, milled on a CNC plotter and special fibre application during laminate production. The tests were conducted according to the ASTM D7332 test standard. The studies showed that the fastener hole preparation method impacts the laminate’s resistance to fastener pull-through. Coupons with holes made with standard (drilling and milling) methods showed fastener pull-through resistance higher, on average, by 6.5% than in coupons with holes placed during plate production. Fastener work to rupture was also higher for coupons with milled and drilled holes. Microscopic observations in UV-light, using a fluorescent penetrant, showed differences in failure mechanisms between individual coupons, especially the lack of fibres in the 0° direction, in immediate vicinity to a hole prepared during laminate application.

Published: June 2019

Abstract
The paper presents the measurement method and results as well as the results of comparative calculations aimed at determination of material data for the package of ferromagnetic sheets insulated with epoxy lacquer. During the test, the package of sheets was treated as a 3D orthotropic material. The values of Young’s and Kirchhoff’s moduli for a pre-compressed package of sheets, in accordance with the used manufacturing technology of the medium and high power electric motors’ rotors, were detennined. The carried out FEM comparative calculations confirmed that the determined mechanical parameters of the package of sheets as a 3D orthotropic material, i.e. Young’s and Kirchhoff’s moduli, for the compressive stress range of 1.0÷2.5 MPa, are included in the linear range. It was assumed that the determined mechanical properties of the package of sheets are necessary at the design stage for FEM simulation calculations of the electric motors’ vibration and strength properties. As a result of the tests, it was found that they should be repeated in order to determine the properties of other sheets or those coated with different insulating lacquer.

Authors: Rosłowicz Adam , Bednarczyk Paweł 
Published: June 2019

Abstract
Design of supersonic H1 rocket by the Rocketry Group of Students’ Space Association (SR SKA) requires an analysis of thermal phenomena occurring in the elements particularly exposed to the high temperature gas. This paper contains a description of the methodology and the results of numerical simulation of heat transfer in the elements of the rocket head. The starting points were the flight conditions (3 characteristic points defined by altitude and Mach number) and independently calculated adiabatic temperature field of the gas. ANSYS Fluent code was used to determine the temperature field on the surface of the rocket. Computed cases were viscous and inviscid flow (for comparison). Based on the results formulated for the viscous case heat transfer boundary conditions, the numerical model and the thermophysical properties of materials were defined. The model was limited to a brass top part of the head and a part of a composite dome. Analytical and empirical method of “intermediate enthalpy” determined distribution of the heat transfer coefficient on the rocket surface. Then the transient heat transfer was calculated with the ANSYS system. It included the range from the rocket launch, moment of maximum Mach number to sufficient structure cooling. The results of the analyses were conclusions relevant to the further development work. Excessive heating of composite structures during the flight has been shown.

Published: June 2019

Abstract
Maintenance of aircraft is a complex process and therefore, in order to optimize the process, integrated information systems are increasingly used. Rapid development and wide availability of mobile devices equipped with powerful processors and with a wide range of modern communication connections suggests their high usability for enterprise IT systems. In the Department of Avionics and Air Armament of the Military University of Technology (WAT) an ERP-class (Enterprise Resource Planning) system, intended to support aircraft maintenance [4] has been designed and developed. The main concept of the system is to store the aircraft related and maintenance information in a central repository, i.e. in databases hosted on a central database server. This solution ensures concurrent availability of the data to a large group of authorized users. The key components of the system include the database server and client applications, which ensure access to centralized information resources, according to assigned user rights. The project involves development of client applications using three technologies: web, desktop and mobile one. Developed client applications have successfully passed integration tests perfomed using sample maintenance data. Currently works on user authorization security and wireless data security are under way.
Estimation of Strength Parameters of Aviation Products Made of Polymer Composites Based on Markov Chain Theory
Authors: Chatys Rafał , Stefańska Anna , Piernik Krzysztof , Stefański Konrad 
Published: June 2019

Abstract
The study investigates the fatigue strength of a component made of a glass composite material with polyester matrix, manufactured using a contact method (I) and by vacuum bagging (II). Modeling was carried out only for composite material II, due to significant spread of the strength of the composite material manufactured by contact lamination I, which means that such a material does not guarantee repeatability of the test results. Estimation of the composite material fatigue strength and residual strength was performed using a mathematical model based on the Markov chain theory. The model assumed that the material failure occurs at certain critical microvolume of the components operating within the plastic range. Observed relationships between the probability values and the distribution parameters for the static strength of the composite components, as well as the load values allow for deriving a fatigue curve equation. Obtained results are presented in the tables.
