    The main purpose of the paper was to identify and present the situation and changes in the level of expenditure on public roads in Poland, taking into account the division of the country into voivodships. The data concerned the period from 2005 to 2017. Sources of materials were the analysis of available literature in the field of road transport, legal acts, data from the CSO database. The comparative method was used in the paper, dynamics indicators were evaluated, the Gini concentration coefficient was calculated and the degree of concentration was presented using the Lorenz curve. Pearson's linear correlation coefficients were also used. A descriptive, tabular and graphic method were used to present the results. Investment outlays on roads apply to both the construction of new roads and the repair of existing ones. Between 2005-2017, the length of public roads in Poland increased by 11% to 422,000 km. Changes in individual voivodships and in subsequent years varied. The largest increase in road length occurred in Podlaskie and Lublin, while the smallest was in Opole. The largest expenditure on public roads was incurred in 2009-2011, which was related to the preparation for the Euro 2012 football tournament, which took place in Poland and Ukraine. Investment outlays were related to the level of economic development of voivodships and the resources of public roads. The only exception to this rule occurred in 2009-2011, when many road investments were centrally financed by the government

    In the paper, we describe a "plug-and-play" configuration of nodes of a tactical network on the basis of XML configuration templates and a network plan, developed during the network planning process. We present the concept of a configuration repository, an XML-based database that stores network structure and configuration data, and describe how the Simple Network Management Protocol is used to apply the settings to network devices. We also comment on a possible use of the next-generation NETCONF protocol for such a task

    An Entropy-Based Network Anomaly Detection Method

    Data mining is an interdisciplinary subfield of computer science involving methods at the intersection of artificial intelligence, machine learning and statistics. One of the data mining tasks is anomaly detection which is the analysis of large quantities of data to identify items, events or observations which do not conform to an expected pattern. Anomaly detection is applicable in a variety of domains, e.g., fraud detection, fault detection, system health monitoring but this article focuses on application of anomaly detection in the field of network intrusion detection.The main goal of the article is to prove that an entropy-based approach is suitable to detect modern botnet-like malware based on anomalous patterns in network. This aim is achieved by realization of the following points: (i) preparation of a concept of original entropy-based network anomaly detection method, (ii) implementation of the method, (iii) preparation of original dataset, (iv) evaluation of the method

Badania dotyczy艂y Polski, z uwzgl臋dnieniem podzia艂u na wojew贸dztwa. Dane dotyczy艂y lat 2005-2017. 殴r贸d艂a materia艂贸w stanowi艂a analiza dost臋pnej literatury z zakresu transportu drogowego, akty prawne, dane z bazy danych GUS. W pracy wykorzystano metod臋 por贸wnawcz膮, pos艂ugiwano si臋 wska藕nikami dynamiki, obliczono wsp贸艂czynnik koncentracji Giniego oraz przedstawiono stopie艅 koncentracji za pomoc膮 krzywej Lorenza. Zastosowano r贸wnie偶 wsp贸艂czynniki korelacji liniowej Pearsona. Do prezentacji wynik贸w bada艅 zastosowano metod臋 opisow膮, tabelaryczna i graficzn膮. Nak艂ady inwestycyjne na drogi dotycz膮 zar贸wno budowy nowych dr贸g, jak r贸wnie偶 naprawy ju偶 istniej膮cych. W latach 2005-2017 d艂ugo艣膰 dr贸g publicznych w Polsce wzros艂a o 11% do 422 tys. km. Zmiany w poszczeg贸lnych wojew贸dztwach i latach by艂y zr贸偶nicowane. Najwi臋kszy przyrost dr贸g nast膮pi艂 w wojew贸dztwach podlaskim i lubelskim, a najmniejszy w opolskim. Najwi臋ksze nak艂ady inwestycyjne na drogi publiczne poniesiono w latach 2009-2011, co by艂o zwi膮zane z przygotowaniem do turnieju pi艂karskiego Euro 2012, kt贸ry odby艂 si臋 w Polsce i na Ukrainie. Nak艂ady inwestycyjne by艂y zwi膮zane z poziomem rozwoju gospodarczego wojew贸dztw oraz z zasobem dr贸g publicznych. Jedyny wyj膮tek od tej regu艂y wyst膮pi艂 w latach 2009-2011, gdy centralnie finansowano wiele inwestycji drogowych

    The main purpose of the article was to identify and present the current situation and changes in higher education in the field of electricity and energy studies in the European Union countries. The specific objectives include determining the degree of concentration of education in the fields of electricity and energy in the EU countries, showing the directions of their changes, types of dominant education in this field, establishing the correlation between education in the fields of electricity and energy and the parameters assessing the achievement of circular economy assumptions in the energy sector. All Member States of the European Union were deliberately selected for research. The research period covered the years 2013–2018. The source of the materials is a literature review on the subject and Eurostat data. For the analysis and presentation of materials, methods such as descriptive, tabular, graphical, dynamics indicators with a constant basis, Gini concentration coefficient, concentration analysis using the Lorenz curve, coefficient of variation, Pearson’s linear correlation coefficient were used. A high concentration of education in the fields of electricity and energy was found in several EU countries, the largest in countries with the highest energy consumption, i.e., in France and Poland. Changes in the level of concentration practically did not take place, only in the case of master’s studies, there was an increase in concentration. However, the EU countries did not differ significantly in terms of the structure of the number of students studying electricity and energy
