Literature Overall of Fatigue Analysis Approaches of Vehicle Components Made of Rubber
130-140Views:316Generally, the most frequently used structural materials are metals which have high strength and stiffness. However, there are many cases when other important properties come to the front, as well as high deformation capacity with elastic behavior, high viscosity namely good damping effect. Due to its above mentioned properties, rubber is widely used in vehicle and automotive industry. Vehicle components made of rubber usually exhibit large deformations. Cyclic finite deformations generate temperature in hyperelastic materials. Furthermore it is necessary to take into consideration the effects of ambient temperature. The mechanical properties of rubber depend on temperature and temperature changes can accelerate chemical alteration processes which lead to the material deterioration and fatigue processes. Research on fatigue behavior and fatigue properties of rubber has a great significance for predicting fatigue life and improving durability of rubber products. There are several studies on the fatigue behavior of rubber-based materials, but there is less research in the fatigue life prediction considering the influence of temperature and temperature changes. First purpose of this paper is summarizing the influence of temperature and temperature changes on the fatigue behavior of rubber. The second purpose of this study is to provide an overview of the state of the art on the fatigue life prediction of rubber with primary focus on the different methods available for prediction of fatigue life under the influence of temperature and temperature changes.

Composition basics and analysis of visual language of the product
381-385Views:206The analysis of the visual language of the product demands deeper analysis of the user’s profile and built behavioral patterns. There is an existing group of factors that have relatively constant nature - gender differentiation, age differentiation, belongingness to specific group – social status, place in hierarchy, race, religion, people with special needs, etc. The analysis of the visual language of the product can be done by analyzing the basic arsenal of the composition - the means of composing form shaping: scale –related to the correct size of the products and their components; proportions –associated with organizing the form plastical and visual order of the whole and its parts; contrast - related to the shape of the product, semantical or bounded to past experience; color –bounded to both formal characteristics and plasticity, as well as to contrast and its meaningful designation; plastic of the form - linked to the proportions and scale, which determines not only the structural and formal characteristics of the products, but also the meaningful reading of the forms. The analysis of the individual composite devices is demonstrated by Ingo Maurer’s lighting fixtures.

Displacement: Translation and Rotation. Differences and Similarities in the Discrete and Continuous Models
104-124Views:297The motion (displacement) of the Euclidean space can be decomposed into translation and rotation. The two kinds of motion of the Euclidean space based on two structures of the Euclidean space: The first one is the topological structure, the second one is the idea of distance. The motion is such a (topological) map, that the distance of any two points remains the same. The bounded and closed domain of the Euclidean space is taken as a model of the rigid body. The bounded and closed domain of the Euclidean space is also taken as a model of the deformable solid body. The map – i.e. the displacement field – of the deformable solid body is continuous, but is not (necessarily) motion; the size and the shape of body can change. The material has atomic-molecular structure. In compliance with it, the material can be comprehended as a discrete system. In this case the elements of the material, as an atom, molecule, grain, can be comprehended as either material point, or rigid body. In the first case the kinematical freedom is the translation, in the latter case the translation and the rotation. In the paper we analyse how the kinematical behaviour of the discrete and continuous mechanical system can be characterise by translation and rotation. In the discrete system the two motions are independent variable. At the same time they characterise the movement of the body different way. For instance homogeneous local translation gives the global translation, but the homogeneous local rotation does not give the global rotation. To realise global rotation in a discrete system on one hand global rotation of the position of the discrete elements, on the other hand homogeneous local rotations of the discrete elements in harmony with global rotation are required. In the continuous system the two kinds of movement cannot be interpreted: a point cannot rotate, a rotation of surrounding of a point or direction can be interpreted. The kinematical characteristics, as the displacement (practically this is equal to translation) of (neighbourhood of) point, the rotation of surrounding of that point and the rotation of a direction went through that point are not independent variables: the translation of a point determines the rotation of the surrounding of that point as well as the rotation of a direction went through that point. With accordance this statement the displacement (practically translation) (field) as the only kinematical variable can be interpreted in the continuous medium.

„Return to the Countryside” – The Retention Possibility of the Sport
292-307Views:551Nowadays, one of the most interesting parts of sociology is the research of the rural areas’ specific features. Within these studies the rural areas ability for survival and to retain forms an important basis. A basic pillar of these, that the youth from these areas become sufficiently motivated to return to their rural homeland after finishing their studies and be able to redound the local social and economic development. Sadly, we experience the opposite of it. Young generations are fleeing to large cities and in medium or long term it leads to the decay of these involved settlements; in worst case scenario the results can be irreversible. In close relation with the aforementioned, we have to mention the specific behaviour of the local – rural – elite, which can be the source of further problems. In the course of our research, we wanted to investigate, that what is the reason that university students, who are studying in large cities don’t want to return or move to rural areas. Furthermore, we tried to give an inside view about their opinions of rural areas and the life in the countryside.

Opinions of Higher Education Students about Internships and Working while Studying
286-297Views:592The importance of working while studying in higher education has a globally growing tendency, and Hungary is not an exception. The demand for the opportunities of student employment has been recognized not only by the students but also by the policy makers of higher education, leading to the introduction of solutions like the obligatory internship semesters or the dual training programs. The current study contributes to the better understanding of this field through the analysis of a database from a questionnaire survey conducted among bachelor students from seven majors of the University of Debrecen during the Fall semester in 2015 (N = 589). The main findings suggest that the students mostly consider the internships as an investment into their future career while the short term compensation and the personal interests have a lower importance for them. About 75% of the students would be willing to work not more than 20 hours a week, and most of them would look for ‘official’ studentwork. For working, they would sacrifice the time connected to the following activity-areas (relative to the other activities in the list, and in descending order): time for leisure (this is the most likely to be sacrificed), for sport, for friends, for family, and for learning (this is the less likely to be traded in for working hours). Willingness to work (measured in daily working hours) seems to be connected to the following factors: major, year of study, how important the activity areas are considered compared to working (learning, family, friends, sports, leisure), and the importance of finding a personally interesting internship.

The Relationship Among Ethics and Conflict Management in Hungarian Metal and Machinery Supply Chains
1-18Views:213It seems that ethics has become an important issue because more and more firms accept ethical codex and make them public as well. On contrary all of us know some stories when unethical behaviour resulted tragedy. Nowadays in business life ethics and responsibility appear as necessary value from the aspect of success. More papers state that ethical behaviour offers various benefits in business relationships. Our paper seeks these positives in empirical way by interviewing members and experts of Hungarian metal and machinery supply chains but we take into consideration the network effects as well. Our survey investigates how fair behaviour can prevent or decrease conflicts in business. The results of our qualitative research show that fair behaviour brings certain benefits but the economic reality and the direction of money flow are dominant. We have met various forms of conflict management and found that respondents want to maintain even very problematic business ties as well.

Menedzsment módszerek az Ipar 4.0 tükrében
507-514Views:892The fourth industrial revolution poses major challenges for organisations in terms of technological aspects and from a management point of view, too. Good (effective) management is vital as it can help overcome the difficulties arising from shortages of skilled labour and from cost-cutting pressures, and it can help improve efficiency of resources. Innovations require management methods that support the introduction of industry 4.0. In my review of the literature, I aim to find out how the current level of sophistication in this new field can help managers of SME to better embrace change. Based on the reviewed literature, from management point of view, organisational structure, leadership style and HR practices are key to creating an atmosphere conducive to learning and innovation. In terms of structure, researchers do not suggest one thing to apply, but emphasise that industry 4.0 is characterised by an unstable, changing environment, so it is worth developing a structure that is characterised by decentralisation, few rules, horizontal communication and collaborative teamwork, i.e. much more organic than mechanical. In terms of different leadership styles, it is the transformational leadership that is the most often mentioned, however, in case of industry 4.0, we need even more because it can have various limitations. Even before industry 4.0, literature has highlighted that the recommended leadership style can be defined as the combination of transformational and transactional leadership; research in industry 4.0 in recent years also emphasises that it is the expanded construction of a knowledge-driven leadership style that blends the two, which can best facilitate innovation and learning. Managers can develop employee skills and improve their learning abilities through a variety of HR practices. So the right structure, leadership style and HR prepare the organisation for industry 4.0 by facilitating learning, improving skills and innovation.

Topology Optimization of Acetabular Cup by Finite Element Simulation
22-34Views:650Hip replacements typically consist of a four-part piece. Our research will focus primarily on the acetabular component. Several different types of materials can be used when creating a hip replacement implant ranging from plastic to titanium. Different materials are used to accommodate for allergic reactions or circumventing potential health risks. Aside from the material, the size of the components plays a factor in terms of durability; a larger diameter head might avoid dislodgement though it could increase wear and tear on the stems through constant friction. A patient’s force applied to the hip replacement is usually measured through a number of physical assessments. Finite element analysis (FEA), a computer-based method of data observation, allows for us to accurately simulate hip forces and their impact on the hip replacements. Through this, it becomes easier to predict and calculate the performance of specific designs. Generative systems can also be used to support performance analysis and optimization through assessing a multitude of cases, many of which apply in real-world scenarios. By applying both systems, we designed and modeled an acetabular cup that when measured decreased the mass from 129 grams initially down to 52 grams, a 60% decrease in total mass. Furthermore, the design we created lessened the trauma on the piece through distributing force across the entirety of the piece rather than specific segments only. This shows an increased durability and life expectancy when compared to usual acetabular cups.

Numerical analysis of effects of an open-pit coal mine to groundwater
70-74Views:292In this study we investigated the hydrogeological problems of an open-pit brown coal mine in the Borsod coal basin with Processing Modflow software. The coal mine is located in the valley of the Sajó-river with high transmissivity overburden layer where the traditional dewatering solutions were not encouraging due to inrush risks and low cost-efficiency. A new way of barrier forming was found out and numerically simulated to prove the efficiency of the solution. Since there are several contaminated sites in the surroundings it was a key factor to assure that the new mine dewatering technique has only a negligible effect on the groundwater regime that undisturbs the known contaminant plumes nearby.

Finite Element Software for Rubber Products Design
13-20Views:488Automotive rubber products are subjected to large deformations during working conditions, they often contact with other parts and they show highly nonlinear material behavior. Using finite element software for complex analysis of rubber parts can be a good way, although it has to contain special modules. Different types of rubber materials require the curve fitting possibility and the wide range choice of the material models. It is also important to be able to describe the viscoelastic property and the hysteresis. The remeshing possibility can be a useful tool for large deformation and the working circumstances require the contact and self contact ability as well. This article compares some types of the finite element software available on the market based on the above mentioned features.

Innovation, Artificial Intelligence in Contingent Work-Force Management
571-590Views:892In recent years, the global use of contingent workers is rapidly increasing despite the increasing quantity of artificial intelligence applications in business. The question is "how these companies leverage the use of artificial intelligence to enhance contingent workforce's management?". The ideal goal of this paper is to develop a purely conceptual application of innovation, artificial intelligence (AI) adjacent to contingent workforce management(CWM). The researcher used qualitative information gathered from various authors and observations to reinforce the usage of AI. One of the critical tools to integrate with contingent workforce management for reduction of time spent on human resource administrative tasks is AI. There must be a transformation of thinking, accepting positive organizational change, utilization of technology and openness to new technology to foster AI. Along with that, integrating contingent workforce management with AI reduces risks and costs, increases efficiency and quality of work. Innovation and Artificial intelligence have been used in five pillars performance of contingent workforce management to mitigate the challenges associated with it.

The Correlation between LGBTQ Tolerance and Economic Development in Europe
31-51Views:529This study analyses the relationship between LGBTQ tolerance and economic development. It uses various indices measuring tolerance and economic data of 48 European countries. Based on previous literature I outlined how economic progress is supposed to have an impact on the social inclusion of marginalised groups. Also, a number of empirical reports are cited providing substantial evidence that tolerance can too shape economic performance. The main aim of this paper is to confirm that these findings in fact hold water in Europe. Having examined the regression analysis of GDP per capita and tolerance, as well as HDI and tolerance, I found that the modernisation theory proved valid on my sample. The other component of my analysis focusing on the sway of social inclusion over FDI showed that more tolerant states attract more foreign capital. These results led me to believe that economic progress and LGBTQ inclusion are interrelated, thus the latter should be considered upon forming policy.

„Return to the Countryside” – a Qualitative Approach of Students’ Opinions About Rural Life
204-216Views:371Nowadays, the research of rural areas’ specific features is one of the most interesting part of sociology. Within these studies the rural areas ability for survival and to retain forms an important basis. A pillar of these, that the youth from rural areas become sufficiently motivated to stay at or to return to their homeland and be able to redound development. We were looking for answers, that how university students, who participated in our current research are thinking about the hungarian countryside, in their opinion what are it’s advantages and disadvantages and it’s possible potentials. In addition, we examined those factors, which are contributing to that respondents who are studying in large cities want to stay there, but at the same time we wanted to explore the opposite factors, those that make tudents to return to the countryside. Last, but not least we investigated a very interesting topic, the relations between the respondents and the rural elite.
