Opis:
The aim of the study is to present the results of the project of ESS, which focuses on the perception of individual safety by Slovak respondents. We studied two indices: characteristics of a safety situation and personal experience with criminality. We compared outcomes from individual results carried out in Slovakia (rounds 2-6) and at the same time we studied safety perception from the generation point of view. The aim of the study is to inform technical public on empirical research of a social-scientific character and to contribute to the enrichment of an information base in a research sphere as well as to contribute to the synthesis of various sciences.
Celem tego artykułu jest prezentacja wyników projektu Europejskiego Sondażu Społecznego ukierunkowanego na postrzeganie indywidualnego bezpieczeństwa przez słowackich respondentów, do czego wykorzystano dwa wskaźniki: charakterystykę sytuacji bezpieczeństwa oraz osobiste doświadczenia z przestępczością. Wyniki poszczególnych sond przeprowadzonych na Słowacji zostały porównane (edycje 2. - 6.), a równocześnie badano zależności w postrzeganiu indywidualnego bezpieczeństwa z pokoleniowego punktu widzenia. Celem artykułu jest zapoznanie także środowiska technicznego z dorobkiem z dziedziny nauk społecznych i wzbogacenie w ten sposób bazy informacyjnej w sferze badawczej oraz zbliżenie różnych gałęzi nauki.

Opis:
Empirical indices concerning social discrimination were applied repeatedly in the extensive sociological research (within The European Social Survey). They were applied in individual six rounds (in two-year cycles). The aim was to determinate the rate of generally perceived discrimination and to find particular reasons (forms) of discrimination (race, nationality, religion, language, ethnicity, age, gender, sexuality). The aim of the study is to inform technical community on the knowledge in the socioscientific field (perception of social discrimination in Slovakia and in other European countries) and to contribute to the enrichment of information base in the research sphere as well as to bring near sciences of different orientation.
W metodyce obszernych badań socjologicznych (w ramach Europejskiego Sondażu Społecznego) w poszczególnych sześciu edycjach (w cyklach dwuletnich) zostały zastosowane wskaźniki empiryczne, dotyczące postrzegania dyskryminacji społecznej. Były one ukierunkowane na określenie stopnia ogólnie odczuwanej dyskryminacji oraz znalezienie konkretnych powodów (form) dyskryminacji (rasa, obywatelstwo, religia, język, przynależność etniczna, wiek, płeć, orientacja seksualna). Celem artykułu jest zapoznanie także środowiska technicznego z dorobkiem z dziedziny nauk społecznych i wzbogacenie w ten sposób bazy informacyjnej w sferze badawczej oraz zbliżenie różnych gałęzi nauki.

Opis:
The purpose of this paper is to present the Monte-Carlo calculations performed to design a special element called gamma blocker (GB), necessary to stop the gamma radiation in the Accelerator-to-Target (A2T) section of European Spallation Source (ESS) linac. Very high levels of gamma radiation emitted backward from the activated target through the beam pipe could effectively block any human intervention close to the beam transport system. The residual dose rate in the linac tunnel was calculated without and with different GBs as a function of time. The fi nal GB material and dimensions are proposed.

Opis:
The European Spallation Source (ESS) is a collaboration of 13 European countries to build the world’s most powerful neutron source for research. The project, situated in the south of Sweden, is approaching the end of the construction phase, and the fi rst scientifi c results are planned for 2023. This paper gives an overview of mechanical design of the gamma blockers (GBs) in the accelerator to target (A2T) and dump line (DmpL) sections. The presence of GBs in the beam line should limit the gamma radiation emitted from the activated tungsten target and beam dump to allow the safe access of the staff to the machine. The presented design allows for effi cient operation and the same shutting time independently of the vacuum status.

Opis:
Employing 2018 European Social Survey data in a multilevel framework, the paper aims to estimate the effect of working for low pay on a wide range of political attitudes and to explain the attitudinal differences between the Central and Eastern European (CEE) and Western European regions based on their differing socioeconomic and political background. The results suggest that it is mainly the lower living standard of inhabitants together with widespread wage inequality and not the specific legacy of the communist regimes that undermine the individual’s perception of influence on politics, political confidence and satisfaction with democracy in CEE. The results also indicate that working for low pay has a significant positive effect on the individual’s trust in politicians, but the relationship is moderated by the country’s economic development and is only significant in rich countries.

Opis:
Numerous studies into the links between interpersonal trust and confidence in state institutions have been conducted since Putnam made the study of trust popular in the early 1990s. As might be expected, both interpersonal and institutional trust tend to be strongly correlated at the individual and the aggregate country level. However, there have been no attempts to determine whether (i) interpersonal trust results from trust in political institutions, (ii) whether the reverse is the case-confidence in government is a precondition for the development of individual trust, or (iii) there are purely reciprocal associations between these attitudes that would appear empirically as a lack of causality. Using data from the European Social Survey 2010 we test these three possibilities using a recursive model

Opis:
In recent years, due to the increasing number of renewable energy sources, which are characterised by the stochastic nature of the generated power, interest in energy storage has increased. Commercial installations use simple deterministic methods with low economic efficiency. Hence, there is a need for intelligent algorithms that combine technical and economic aspects. Methods based on computational intelligence (CI) could be a solution. The paper presents an algorithm for optimising power flow in microgrids by using computational intelligence methods. This approach ensures technical and economic efficiency by combining multiple aspects in a single objective function with minimal numerical complexity. It is scalable to any industrial or residential microgrid system. The method uses load and generation forecasts at any time horizon and resolution and the actual specifications of the energy storage systems, ensuring that technological constraints are maintained. The paper presents selected calculation results for a typical residential microgrid supplied with a photovoltaic system. The results of the proposed algorithm are compared with the outcomes provided by a deterministic management system. The computational intelligence method allows the objective function to be adjusted to find the optimal balance of economic and technical effects. Initially, the authors tested the invented algorithm for technical effects, minimising the power exchanged with the distribution system. The application of the algorithm resulted in financial losses, €12.78 for the deterministic algorithm and €8.68 for the algorithm using computational intelligence. Thus, in the next step, a control favouring economic goals was checked using the CI algorithm. The case where charging the storage system from the grid was disabled resulted in a financial benefit of €10.02, whereas when the storage system was allowed to charge from the grid, €437.69. Despite the financial benefits, the application of the algorithm resulted in up to 1560 discharge cycles. Thus, a new unconventional case was considered in which technical and economic objectives were combined, leading to an optimum benefit of €255.17 with 560 discharge cycles per year. Further research of the algorithm will focus on the development of a fitness function coupled to the power system model.

Opis:
The wind power which has been expected to be a promising alternative energy source can bring new challenges when it is connected to the power grid due to the fluctuation nature of the wind and the comparatively new types of its generators. This paper illustrates a possible solution to mitigate these integration issues of the wind power by application of the energy storage to the wind farm in power systems focusing on its short-duration perspective. The simulation model for the Energy Storage System (ESS) connected to the wind farm is implemented using the Power System Simulator for Engineering(PSS/E) which is one of the most widely used program for the power system analysis in US. Employing a sample power system, the control effect of the ESS for mitigating the wind generation related power quality issues by suppressing the power flow fluctuation of the wind farm, and improving power system stability is validated. The counteracting effect of the ESS in the wind farm to the disturbance on the grid is also shown.
