The Budapest Business School ) is a public business school specialised in business studies and social science located in Budapest, Hungary. Founded in 1857 by merchants and bankers of Austria-Hungary in order to establish the economic vocational training of higher education in the empire and in Central Europe. BBS is officially the second oldest business school in the world.The Budapest Business School is Hungary's market leading and largest business school and conducts education and research in leadership, economics, operations management, marketing, entrepreneurship, organizational behavior, and other areas; as of this time, its most acclaimed programs are finance, accounting, strategic management, and tourism. The School offers a wide range of graduate-level academic programs and concentrations. In the latest academic year the Budapest Business School offers 12 Bachelor's degree programmes, in case of most programmes in English, French, German and Hungarian language as well. Offers 12 Master's degree programmes, of which the most populars are Master of Finance, Master of Management , Master of International Business and Master of Tourism Management. Moreover offers PhD in Management doctoral school, 51 post-graduate professional qualification with either Hungarian, English, German, Dutch or French state degree accreditations, being recognized within the European Union and throughout the world.

The paper assesses the impact on the fluctuation of the shallow-groundwater table of the diversion of the Danube upstream from the Gabčikovo/Bos hydroelectric power plant in a hydraulically connected, geologically identical, and structurally not decomposable geological area in North-West Hungary. On the basis of shallow-groundwater level monitoring data the impact was traced back to the effect of the Danube's changed flow course, and quantized for the whole study area.To this end the influence of the river had to be separated from the effect of precipitation. The means chosen was the application of dynamic factor analysis to the registered hydrograph time series. We conclude that the originally homogeneous and dominant effect of the Danube has split and now consists of a diverted and a returning component (downstream from the power plant), and that this is a likely cause of ram-effect and river bed clogging. Furthermore the effect of precipitation ceased to be suppressed, and came to the fore. © 2014 Elsevier B.V.

The p-graph-based workflow has been introduced for modeling administrative processes in earlier papers then it was completed with necessary descriptors to conceptualise the dynamic model and we determined the initial model as well as the operational algorithm of the activities. Starting from model this this paper examines the simulation possibilities of workflows modeling administrative processes. The main goal of the simulation is the dynamic analysis of the workflow model, filtering of bottlenecks and the optimization of resources. Considering that we talk about the simulation of administrative processes we look thoroughly into the precise representation of the flow of documents and the simulation of the operation of activities. © 2013 IEEE.

In most of the world along with urbanization came the deterioration of surface waters. The case of Hungary's Lake Balaton (the largest shallow freshwater lake in Central Europe) and its catchment area was no exception. In the second part of the twentieth century it became clear that measures had to be taken to prevent further water quality deterioration. In order to do so, the Kis-Balaton Water Protection System (KBWPS) was established. To measure its effectiveness in filtering Lake Balaton's water input, total phosphorus and total nitrogen loads are regularly estimated. In this study the practice of temporal sampling frequency estimation is described using data series from the KBWPS in order to suggest a sampling frequency that is suitable for estimating annual nutrient loads and still produces a dataset from which environmental processes can be followed. In this case, temporal sampling frequency estimation was conducted using variogram analysis, before which trend removal was performed on four sampling sites and two daily sampled parameters for the years 1993-2007. Although the calculations were only carried out on two parameters they are applicable to other environmental parameters as well. Nutrient load estimation is used as a verification tool. The result of the variogram analysis pointed towards a three-day sampling frequency for the whole KBWPS in the case of total phosphorus and total nitrogen (if the purpose of the monitoring is nutrient estimation). This reduction in sampling frequency would make an approximately 50% cost reduction possible. The study gives an example of sampling frequency estimation which is a key question in every aspect of environmental science, so that hopefully it will be useful for scientists dealing with water protection issues. © 2012 Elsevier B.V.

In the German mathematical educational system the graphical calculator is not only allowed but also recommended in secondary grammar school. Therefore in the Deutsche Schule Budapest, where the graphical calculator basedonGermancurriculumisalsoallowedandrequired, anexperimentwere conducted with two groups in grade 10. This experiment was performed in these groups for 46 lectures. The parallel teaching with and without graphical calculator was the main emphasis in the lectures. We consistently used the “old” with the “new” method simultaneously. The aim of the experiment was to determine how the graphical calculator can be helpful in the mathematics courses when it is used for introduction of differential calculus. To apply calculators for mathematical problems secondary-school students have to understand the meaning and the concepts of mathematical formulas confidently, they have to convert and interpret the parameters and substitute them into the right formulas. Besides, they have to know correctly the functions of the calculator in practice. Even better students can have difficulty in using the calculator because they need different notations on paper and booklet operation and on the software or graphical calculator. While it has been suggested that appropriate use of the graphical calculator can support students in differential calculus, the following issues were considered: how and how deep the differential calculus should be instructed with and without graphical calculator so that the students can build the right concept image. © 2015, Eszterhazy Karoly College.

Lake Balaton is the largest shallow freshwater lake in Central Europe. Its water quality is mainly affected by the supplying rivers and other water sources. The primary source is the Zala River. The water of this river used to be filtered by the Kis-Balaton wetland (KBW) before entering Lake Balaton at Keszthely Bay. In the course of the nineteenth century, water level modifications at KBW shrank and it lost its full capacity to function as a filter for the Zala's waters, so the nutrient load of Lake Balaton greatly increased, and its water quality started to deteriorate. This is the reason an artificial extended wetland called the Kis-Balaton water protection system (KBWPS) had to be constructed-to retain the inorganic nutrients at the mouth of the Zala River and stop the further degradation of Balaton's water quality. In this study, Morlet wavelet spectrum (periodicity) analysis and autocorrelation (memory) analysis were used with weekly chemical, biological and physical data for the KBWPS for the period 1993-2007. We compared the periodicity and the memory of the parameters in the two different habitats of the KBWPS and the Zala River. We also analyzed the tracking capability of the periodical seasons of the two phases (the complete Phase I, and the incomplete Phase II) and the river. The results showed that the incomplete Phase II is unable to conserve the periodicity and sustain long memory because of the shading provided by the macrophyte cover and the extra inflows. In conclusion, we were able to point out the dependence of the system's processes on temperature and climate conditions with methods that have not yet been used for this kind of purpose. © 2010 Elsevier B.V.
