Simulation of Hot Rolling by Cellular Automata
190-195Views:344Our research is focusing to one of the most complex and important production step of flat rolled products that is the simulation of hot rolling. During hot rolling two phenomena as work hardening and the process of regeneration of crystals has strong influence for physical properties of microstructure of aluminium alloys. It needs to be taken into account in case of rolling technology steps and development. When we talk about aluminium the dynamic softening in fact it is dynamic recovery that is followed by dynamic recrystallization. It goes in the same order of magnitude rate. But in steels the recovery has only a minor effect. Hot rolled and newly modified grain structure is influenced by these dynamic phenomena. Hot rolled grain structure goes through significant changes under further production steps like cold rolling and heat treatments. But aside from these intermediate production steps the microstructure that we get after hot rolling has significant effect for mechanical and grains structure of the final flat rolled product. Proper technology planning is essential that for cellular automata simulation method can ensure useable and good solution for the simulation of recrystallization.

Optimizing the combustion processes of a small scale solid fuel-fired boiler
358-369Views:299Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.

What Image is Conveyed by the Webpages of Hungarian Higher Education Institutions?
355-370Views:319This exploratory study analyses the online higher education marketing practice in Hungary. It examines the homepages of all of the state accredited higher education institutions in Hungary. The selected dimensions of the examination are to measure different aspects of openness expressed by the image published on the homepages to their audience. State vs. non-state financed (and as a sub-category of the latter: church financed) institutions are compared along these dimensions, as well as universities vs. colleges (according to their status both before 2000 and present). The main finding of the research is that there is a statistically significant evidence that the homepages expressed different images for the analysed institution groups. Differentiating signals between state financed institutions vs. non-state financed institutions, as well as between universities vs. colleges were identified: the number of pictures published on the main page, the presence of sliders, the accessibility of the website to people with visual impairment and to non-Hungarian speakers, and the access to social media. State institutions and universities were found to publish a more open image via their homepages than the non-state financed institutions and the colleges.

Investments and Their Financing Risks and Risk Management Trends in the Last 10 Years
184-203Views:366The purpose of our literature review was to understand the state of research related to management of risk of corporation’s investments and their finance within the past 10 years. Nowadays the risk management and problem solving are characterized by holistic approach and complexity - and these tendencies we can see clearly. We need to examine the likvidity, financing and investment questions together, because of the interactions between them. They can influenced the corporate value together. The role of risk management in the investments is the cash-flow smoothing (we mean: cash-flow generated by investment). The field of corporate finance is noticeably inseparable from other areas of business science (at least in the empirical analyses), and even technical issues, like risk management, have long been considered suitable appropriate in an integrated form. The financial and operational hedging has become indispensable elements of the managerial toolbar. The consequence of crisis (from 2007) promotes the birth of many studies that justify it. The researchers are paying close attention the transaction costs, such as costs of contracts or agent costs, and the losses due to information assimetry. The statements of behavioral finance connection with managerial decisions mean important additives in this field.

Management Practices from Christian Point of View
14-30Views:367Globalisation is a complex and worldwide process overarching historical times and continents. However the phenomenon brought efficiency and new opportunities to companies, providing practically free access to raw materials, labour and knowledge, it also caused negative effects like the degradation of the biosphere, greater social and economic inequality especially in the developing countries. There are some companies operating worldwide which have acquired great economic power and influence. and governments have only limited possibilities (if any) to regulate their operation. The expenses of profit maximisation are high, which are often ‘paid’ by the socialnatural environment (as externalities) and/or by humans. The aim of our study is to overview how current business relations could be formed to be more „human friendly”. The research is done from a Christian philosophy point of view, focusing on the employees as the major stakeholder group of the comanies. As part of the study some practical examples and Hungarian organisations related to this topic are introduced in order to highlight the relevance of the topic.

Financial Performance Measurement with the Use of Financial Ratios: Case of Mongolian Companies
20-32Views:456The aim of this paper is to examine the efficiency of Mongolian 100 public companies listed on Mongolian Stock Exchange (MSE) which are divided into 6 major sectors. This study conducts the performance of companies in terms of profitability by using three different output variables i.e., revenue, pretax profit and ROA (Return on Assets). In the beginning of this research, nine variables which are connected with profitability are chosen as output variables, while 24 variables expressing growth, financial structure, solvency, and turnover together with some fundamental financial data are chosen as input variables. 10 variables out of 24 input variables, which determine the financial structure, solvency, and profitability, are chosen as input variables based on the calculation of stepwise regression analysis. Stepwise regression, multi co-linearity analysis are made by SPSS and DEA (Data envelopment analysis) is evaluated by benchmarking package in R excel statistical program covering the period of 2012-2015. This paper uses the input-oriented version of DEA based on financial ratios and some crucial components of a financial statement. The results of DEA show that food and grocery sector was the most efficient, and mining sector was at the second place by its efficiency, while agriculture and service sector were the worse than other sectors.

Sport Consumption, Fan Engagement, Sport Statistics – Post-specific Passing Characteristics in Football
Views:879Digitalization and the explosive development of technology have led to significant changes in football. Due to the increasing amount of data available through various sensors and other data collections, we can observe the rise of data-centric, analytical and statistically oriented thinking in football, which is also of interest to fans. Digitalisation is also closely linked to sports consumption, which is why we have seen significant changes in this area in recent years. The pandemic has further amplified the speed of digital transformation in the sports industry. One of the most important contents for sports organizations and their fans is the in-depth sports statistics and analysis that enhances the consumer experience. In our study, we examined the most common performance indicator in football, passing. Our goal was to examine the position-specific pass characteristics in detail, therefore we also examined different pass properties in our research. As a model for our analysis, I chose the premier league, which has the highest UEFA coefficient. The three rounds (rounds 30-32) of the championship season 2019/2020 have been recorded and analyzed in terms of passes. there was a significant difference between the average number of passes per game between defensive and offensive players (t=7,988, p<0.05). There is also a gradual decrease in the number of passes attempted per match and the accuracy of the pass in the examination of the middle positions when examining the positions in the depth of the pitch. For both pass accuracy and average pass count, the decreasing ranking corresponds to the position of positions on the pitch (order: 1, central defender 2, defensive midfielder 3, inside midfielder 4, attacking midfielder 5, striker). In the value indicator of the position for passes, offensive positions performed more effectively than defensive positions. The extreme positions also stand out among the attacking positions, where in the case of the position value per pass number, 23.3% of the total test was completed and 14% of the amount of the established position value indicators was provided by these posts. Overall, our study points to post-specific pass characteristics and, knowing this, we can state that the comparison of players' passing performance is relevant if the players are in the same or related positions.

Properties of Cellulose Sheets Modified with Potassium-Humate and Copper (II)-Sulfate
276-285Views:242Throughout our research we have made potassium-humate from brown coal of Dudar. With potassiumhumate and copper(II)-sulfate we made test sheets of linter cellulose fibers. The surface energy, surface wettability, CIE Lab color-coordinates changing, bending resistance and tensile strength of the produced test sheets has been examined. There was no big difference in the different samples during surface energy and wettability testing. Examination of mechanical properties suggests that potassium-humate content increases bending resistance of the test sheets. The bending resistance of samples increased by 32%, 100% and 336% compared to the control test sheets while adding potassium-humate.

Demand and Supply in the Talent Market
142-149Views:402In Hungary, the emergence of a talent market for organizations is due to the growing demand for talented workers. The talent's definition, the exploration of the factors affecting the talent market's demand and his supply are necessary to the overview. With the emergence of the talent market, we will also carry out an important analysis of the changes in the labor market in Hungary as well as the shortage of labor shortages. In the labor market today, different generations are present, who have different expectations for their employer and work environment. The lack of skilled workers is attempted by organizations with different methods. One of these is the ability of companies to become a talent-magnet, resulting in a higher number of employees in their area of activity. In areas where labor shortages are high, more and more attention is paid to automating processes. During the research, I worked on the related literature and studies to determine the factors influencing the talent market.

Bread Making and Consumption Habits in the Gluten-free Diet
252-262Views:472Celiac disease is a genetic autoimmune disorder characterized by sensitivity to gluten. Gluten is a protein found in many grain products (wheat, rye, barley and oat). When a person with celiac disease consumes gluten, his/her immune system perceives the gluten to be a harmful substance and reacts negatively. The only treatment for people with celiac disease is lifelong adherence to a gluten-free diet. Bread is a basic and frequently consumed food made from basically gluten-containing grains. Bread plays essential role in the Hungarian dining habits, thus bread consumption in the gluten-free diet is a challenging question. The aim of our empirical research was to investigate the gluten-free bread making and consumption habits of people following a gluten-free diet.
