Sections of Hungarian Contemporary Architecture and Fine Arts
115-122Views:173In my study I have examined the sections of Hungarian contemporary architecture and fine arts. In the historical overview it has become clear that two turning points have influenced contemporary arts: the total art work (Gesamtkunstwerk) of the Ghotic and Baroque styles. I listed the sections in three categories: metamorphosis, relationship and section. The sections are the highest level of these categories. I explained my research in detail by analyzing these sections, at János Megyik's art and his Gate statue at Life Science building and library at the University of Debrecen.

Frank Lloyd Wright and the Imperial Hotel in Tokyo
129-135Views:100Frank Lloyd Wright is one of the most prominent architects of the first half of the twentieth century. Wright's architecture was given a name organic, also known as organic architecture, which means the effort to harmonize the buildings and the surrounding natural environment. During his life he designed a lot of buildings, but perhaps one of the most important buildings which received the biggest negative and positive response is the Imperial Hotel in Tokyo.

Experimental Study of Connections with Hardwood Studs
26-34Views:140Attitude change is needed in design of timber structures. Truss girder made of timber elements wi th small cross sections can be used on large spans. Constructing structures with the use of these prefabricated trusses reduces the need of in-site work, and makes the use of ti mber structures economic. Rods of truss can be connected with the use of hardwood stud. On this way all steel components can be eliminated from the truss, so it can be used in aggressive environment as well. Dowel type connection, with hard wood stud is the subject of the present research. Hardwood studs were investigated individually and also as the part of separated connections of the truss girder.

Wind Energy Harnessing Options at Buildings
51-58Views:106Our goal was to develop a wind turbine system which could be applied in urban areas where the wind power has low potential, such as the cities in the “Alföld” region. The proposed system is able to harness more wind power at lower wind velocity than the commonly used ones, by using advantageo us properties of the flow in tunnels.

Analysis of Smart Photovolatic Systems
67-75Views:107Nowadays more attention should be paid to the electric power generation wi th renewables. The photovoltaic systems have several benefits. But this systems power output could drastically drop by numerous external phenome. To avoid these, we introduce the so called “TIGO” power opti mizing system features and the monitoring of the deployed system on an existing building. We examine the produced energy for a given time period.

Vehicle dynamics modelling of an electric driven race car
106-114Views:138In the following we are presenting a vehicle dynamics simulation program developed in MATLAB environment. The program is capable of calculating the dynamics functions of a vehicle from its technical data. The program has been successfully applied for the optimization of the technical data of an electric driven race car that was designed and constructed at the Department of Mechanical Engineering of the University of Debrecen.

Fémhabstruktúrák elemzése és geometriai modellezése
145-152Views:145The development of an efficient procedure for 3D modelling and finite element simulation of metal foams is one of the greatest challenges to engineer researchers nowadays. Creating 3D CAD model is alone a demanding engineering task due to its extremely complex geometry, and the proper finite element analysis process is still in the center of the research. The aim of this project is to analyze the related literature and to adapt the results may be considered

Utilization of grinding dross remained from production process in order to minimize waste and save costs
18-25Views:114It is i mportant to reuse wastes from production process particulary. In the course of metal roughing grinding dross comes off. Its oil content is high enough to treat i t wi th piston briquette machinery and by this methode part of this oil can be retrievable and returned to production. By means of making a ma terial balance I determined how much effective the machinery has to be to work the dross and its payback was also calculated.

Environmental Considerations in Aircraft Manufacturing Industry Through the Example of Boeing Andairbus Companies
59-66Views:140Aircraft manufacturing industry has developed dynamically in the last decades. Reinforced polymers have become the most dominant raw materials, while the recycling rate of the generated industrial waste has also increased. The fuel efficiency of the engines has increased, and the emitted CO2 per capita has significantly fallen. However, the environmental impact of the aircraft manufacturing industry seems to reach a permanent level. In this study, we have analyzed the environmental impact and the environmental considerations of the aircraft manufacturing industry through the examples of Boeing and Airbus companies. Our goal was to determine the relation between industrial growth and the environmental impact, particularly to the potential innovations.

Assessment of Mycotoxin Contamination of Foods
90-96Views:196According to RASFF reports, in the present, pathogenic microorganisms, pesticide residues and mycotoxins are the most frequent food contaminants. In 2014, 12% of the total notifications were caused by mycotoxin contamination. In this study we have analyzed the RASFF notifications that are related to the mycotoxin contaminations. It can be stated that aflatoxin is responsible for 90% of the total mycotoxin notifications, and the total notification number has decrease by 40% since 2004. However the number of oc hratoxin-A notifications are slowly increasing. Aflatoxin was mainly detected in nuts and nut products and oil seeds, especially groundnuts, while ochratoxin-A was detected in fruits (more than 85% in figs) and spices. The number of deoxynivalenol and fumonisin notifications were significantly less, however some appear every year for cereals and bakery products, especially corn and wheat. Zearalenone and patulin were detected only in 16 and 18 cases but 22% of the patulin notifications are related to baby food, so the tracking of patulin is really important.

Examination of Innovative Wastewater Treatment Method for Chemical Treatment of Municipal Wastewater
136-144Views:368The VízTEC Ltd. and Debrecen Waterworks Co.’s management mutually expressed their intention, that to designate a period of research examining the Debrecen Waste Water Treatment Plant’s (WWTP) intensification. During this period, the newly developed product, VIRON Plus 40 coagulating agent will be tested provided by the VízTEC Ltd. The aim of using the VIRON Plus 40 coagulating agent is the examination of intensification opportunities of Debrecen WWTP. The functions of the new generation of coagulants go beyond inorganic phosphorus precipitation and are growing. A modern WWTP is not only clean the water but also produces energy and usable sludge product. The appropriate energy balance, cost efficiency and carbon dioxide emissions reduction get increasing emphasis in WWTP’ operations.

Optimization of Automotive Industry’s Manufacturing Process with Lean Tools
81-89Views:393Lean plays i mportant role in industrial environment. Automotive industries use lean tools in order to reduce cost and i mprove productivity. To achieve the company's objectives and so lve the detected problems I also used lean tools. By using lean tools we want to decrease total process cost (TPC). In order to achieve this target, the three-shift production has to reduce in two-shift production, which result decrease in the human resource costs and production costs. In order to reduce shifts we have to increase overall equipment efficiency (OEE) and eliminate minimum 50% of wastes by implementing 5s methodology, using Poka-yoke and scheduled maintenance.
