Fatigue Within the EU’s Eastern Partnership: The EU Role in the “Neighbourhood Of Crisis”
Authors: Rakutienė Sima 
Published: March 2019

Abstract
Since 2004, when the European neighbourhood policy was established, the European Union has already spent billions of euros to finance the new neighbourhood policies for creating more stable and more cooperative relations with eastern and southern neighbours. However, increased security concerns and challenges, less stable and less prognostic relations seem to have produced the opposite result of what was sought, and so Europe is experiencing a “neighbourhood of crisis”. Did it fail? What strategy has the EU been using within the last 15 years in relations with its neighbouring countries? What specific tools and instruments have been adapted? Did the renewal of European neighbourhood policy introduce any completely new strategic elements? This article examines these questions, focusing on three perspectives suggested by role theory: intentional, interactional and institutional. The study applies qualitative research methodology and claims that the EU has been seeking to transmit not just EU values and standards but also internal institutional practices and modes of EU governance.
Economic Scheduling of Microgrid Based on Energy Management and Demand Response
Authors: Chamandoust Heydar 
Published: March 2019

Abstract
Currently, microgrids are regarded one of the main substations in distribution networks that generate electrical energy locally. The advantages of microgrids include easy management, optimization, and highly reliable supply. In this paper, the recommended model is based on economic and emission optimal scheduling in connection to the main grid mode; implementation model implies the short-term mode with optimal operation units and the use of real-time pricing (RTP) plan. In this study, a multi-objective function for operating costs and emission with the augmented ɛ-constraint method has been considered; fuzzy decision-making process has been employed to obtain the best solution. In addition, it has been considered that a microgrid has interruptible and shiftable loads that can participate in demand response programs. The presented results have been evaluated based on different demand response programs.
Appropriateness of Numbers of Receptive Fields in Convolutional Neural Networks Based on Classifying CIFAR-10 and EEACL26 Datasets
Authors: Romanuke Vadim 
Published: March 2019

Abstract
The topical question studied in this paper is how many receptive fields (filters) a convolutional layer of a convolutional neural network should have. The goal is to find a rule for choosing the most appropriate numbers of filters. The benchmark datasets are principally diverse CIFAR-10 and EEACL26 to use a common network architecture with three convolutional layers whose numbers of filters are changeable. Heterogeneity and sensitiveness of CIFAR-10 with infiniteness and scalability of EEACL26 are believed to be relevant enough for generalization and spreading of the appropriateness of filter numbers. The appropriateness rule is drawn from top accuracies obtained on 10 × 20 × 21 parallelepipeds for three image sizes. They show, knowing that the number of filters of the first convolutional layer should be set greater for the more complex dataset, the rest of appropriate numbers of filters are set at integers, which are multiples of that number. The multipliers make a sequence similar to a progression, e.g., it may be 1, 3, 9, 15 or 1, 2, 8, 16, etc. With only those multipliers, such a rule-of-progression does not give the number of filters for the first convolutional layer.
Methane emissions and demethanation of coal mines in the Upper Silesian Coal Basin between 1997 and 2016
Authors: Dreger Marcin , Kędzior Sławomir 
Published: March 2019

Abstract
Between 1997 and 2016 we observed important changes in hard coal extraction and methane emission in the Upper Silesian Coal Basin. Hard coal extraction in the near future will be very dangerous because it will be necessary to reach deeper methane-rich coal seams. Permanent monitoring of the volume of emitted and captured methane is necessary to combat the methane hazard. The predictability of gaseous hazards are important in order to keep underground work safe. We gathered and analysed data from three coal companies: Katowice Coal Holding, the Coal Company, Jastrzębie Coal Company and in the whole of the Upper Silesian Coal Basin for the last twenty years and this allowed us to notice changes and CH4 trends in ventilation emission and demethanation. There is a decrease in the extraction of hard coal from year to year. At the same time there is an increase in the total methane emissions which forces actions aimed to effective contracting the methane hazard. Specifically, methane emission has been increasing for years, making hard coal extraction very dangerous. We observed increases in CH4 vent emission and volume of methane coming from underground drainage systems. Much more methane is released during hard coal extraction at deeper mine levels. Throughout the entire research period the methane hazard increased. Therefore, the development of modern technologies for methane capturing should contribute to improvement of hazardous conditions for coal mining in the basin.
Landscape transformations in the alluvial fan of the River Little Vistula (Mała Wisła) in Poland from the 18th century to the present
Authors: Czaja Jakub 
Published: March 2019

Abstract
Development within the River Little Vistula valley undoubtedly started at the very beginnings of the Polish state. At that stage, human activity focused on finding and adapting sites that were suitable for permanent settlement and also on utilising the resources found in the valley and afforded by the river such as fishing and shipping opportunities. The shape of the River Little Vistula alluvial fan also allowed the construction of numerous canals branching from the river channel, on which mills, fulleries and sawmills were established. The characteristics of the landscape changes which have taken place in the study area have been presented on the basis of analyses of large-scale (1:28,800) topographic maps from the mid-18th and 19th centuries, modern topographic maps and also from visits to the study area (General-Mappa des Merzogthums Ober-Schleisien 1763–1764 and Übersicht der Militar Aufmahme von Mähren und Schlesien, 1839-1840). It was found that landscapes of the River Little Vistula alluvial fan are “landscapes of valleys and plains subject to water accumulation and floods”. Such areas are characterised by the presence of groundwater at low depths and are subject to periodic flooding by river waters, which are rich in mineral substances. Their habitats include riparian forests and flood meadows, which have often been transformed into arable fields. Characteristic types of soils in these areas include alluvial soils and peats, and typical elements of the landscape are water bodies, mainly fish ponds.
Marketing Quality of Texts Posted on the Websites of Rural Tourism Facilities in Poland
Authors: Król Karol 
Published: March 2019

Summary

Subject and purpose of work: The subject of the research were texts published on the websites of rural tourism facilities in Poland, and the purpose of the work was to assess their marketing quality.

Materials and methods: The evaluation of the marketing quality of the texts was carried out using the web application Audyt Hekko (Blink) on a collection of 842 websites of rural tourism facilities.

Results: Texts with a low (poor) marketing utility (as assessed by the testing algorithm) were found on 362 websites, which constituted approximately 44% of the set. Approximately 46.5% of the websites contained texts whose marketing utility was sufficient. Texts posted on 10% of the analysed websites were rated as useful for marketing.

Conclusions: The semantic evaluation of the texts published on most rural tourism facilities websites has shown that they have been written in the language of benefits, with the use of phrases that may arouse interest and curiosity. At the same time, however, they required optimization and a greater marketing orientation.
Public and Private Lives: Judith Butler’s Grief and the Loss of Black Self
Authors: Maze Jacob 
Published: March 2019

Abstract
By looking at Butler’s theories on grief and mourning, I focus on her concept of ecstasy, or the state of being outside of one’s self, which illustrates the dependency individuals have on social norms as well as the vulnerability such a system of recognition entails. Using this framework, I discuss how the private and the public spheres can construct public bodies. If this happens, individuals can have little say over how their bodies are socially signified. To show this, I use the case of Black women in the USA, where systemic oppression constantly draws their bodies into the public’s eye.
Rola Avarského Kaganátu Pri Vzniku Slovenčiny
Authors: Braxatoris Martin , Ondrejčík Michal 
Published: March 2019

Abstract
The paper proposes a basis of theory with the aim of clarifying the casual nature of the relationship between the West Slavic and non-West Slavic Proto-Slavic base of the Slovak language. The paper links the absolute chronology of the Proto-Slavic language changes to historical and archaeological information about Slavs and Avars. The theory connects the ancient West Slavic core of the Proto-Slavic base of the Slovak language with Sclaveni, and non-West Slavic core with Antes, which are connected to the later population in the middle Danube region. It presumes emergence and further expansion of the Slavic koiné, originally based on the non-West Slavic dialects, with subsequent influence on language of the western Slavic tribes settled in the north edge of the Avar Khaganate. The paper also contains a periodization of particular language changes related to the situation in the Khaganate of that time.
Lexikálny Význam V Recepcii
Authors: Dolník Juraj 
Published: March 2019

Abstract
Asking first about how the lexical meaning manifests itself as we experience it in a communicative event, the author explores the background of the ways in which we are able to perceive the meaning of words in texts. One useful way of thinking about how recipients react to the words in utterances is in terms of behavioural and actional lexical meaning. The first refers to the understanding of meaning, the second corresponds to interpretations of words when the recipient does not succeed in the process of natural understanding of words. These terms lead to questions about the rationality of language. One aspect of this rationality is the function of the intentional­emergent mechanism that adjusts the interplay of automatic and deliberate use of language. This mechanism has its roots in the fundamental human nature: we are behavioural­actional beings. Pragmatic analysis sheds light on how hearers understand and interpret what they hear with regard to their conceptual knowledge associated with words.
Lexéma Hrať V Trénerskom Komunikačnom Registri – K Vymedzeniu Registrovo Motivovaného Významu
Authors: Slančová Daniela , Slančová Terézia Kovalik 
Published: March 2019

Abstract
The study analyses the meaning and usage of the lexeme hrať [‘to play’] in coach register of the volleyball coaches coaching girls and boys of older school age. Theoretically, it is based on the theory of sports games, theory of communication register, theory of lexical motivation and complex concept of meaning without strict borders between semantics and pragmatics. Empirically, it is based on the analysis of tri­modal (audiovisual­graphical) corpus of the speech of two volleyball coaches (one of a girls team, one of a boys team), each of three training units and three games (50 917 tokens). The concept of register motivated meaning is explained. While analysing meaning of the lexeme hrať and its collocations (116 types of collocations), the author goes from the general meaning of the lexies (hrať 1 = to do a sports activity; hrať 2 = to present a sports performance), through its context specification to its situational actualization.
K Dynamike Štylistiky Slovnej Zásoby V Súčasnej Online Mediálnej Produkcii Názorového Typu
Authors: Patráš Vladimír 
Published: March 2019

Abstract
The paper is aimed at nature, manifestation and mutual relation of two contradictory trends in alternative online periodicals with opinion­based articles (i.e. articles expressing authors’ opinions). On the one hand, the persuasive function of articles, aimed at shaping readers’ opinions, changes to pretend, change or cover the substance of a topic, usually on the edge of manipulation. This effect is reached by: a) gradation of emotions and usage of stylistically marked lexemes, b) shifts in meaning behind a common or presupposed context, c) preferring occasionalisms, d) deliberate desemantization of lexemes, e) revitalisation of semantics and stylistics of lexemes moving between the centre and the periphery of the lexicon. On the other hand there are also articles containing notional, unmarked and neutral words as basic words. Their function is to strengthen informative basis of articles. In order to reach a persuasive effect, both contradictory trends support an activity of competitive and cooperative relations. Lexicon of analysed articles becomes a vehicle for collision of persuasive and informative functions – the source of genre syncretism in media communication sphere. Research corpus consists of articles belonging to the rational type of journalism, appearing in internet alternative periodicals aimed at major geopolitical conflicts and related to crisis situation or crisis communication sphere. They cover especially public events, heated events and confrontation in the context of international political communication usually with the evidence or manifestation of geopolitical power. The corpus for stylistic analysis, interpretation and generalisation includes selected Slovak alternative online and opinion based periodicals.
Posesivní Genitiv Redivivus
Authors: Uličný Oldřich 
Published: March 2019

Abstract
In the contemporary Czech, in both spoken and especially in written form, possessive adjectives are replaced by possessive genitives, which are originally colloquial constructions only. In the last stage of this development, the postpositive genitive changes into prepositive: Klárčina maminka, maminka Klárky, Klárky maminka (‘Klárka’s mother’). The Czech language thus loses another means of inflection and gets closer to an agglutinative language type. This change (deflective tendency) is also supported by the loss of introflexion, i.e. the loss of morphophonological alternations, in our example k – č, in other cases r – ř, g – ž, ch – š, etc. (Klárčin – Klárky [‘Klárka’s’], sestra – sestřin [‘sister’s’], Olga – Olžin [‘Olga’s’] etc.).
Klára Buzássyová V Kontexte Sémantizácie Slovenskej Lexiky Cudzincom
Authors: Pekarovičová Jana 
Published: March 2019

Abstract
This paper deals with the characteristics of the scientific research of the renowned Slovak linguist Klára Buzássyová who – as a lecturer at the Studia Academica Slovaca summer school of Slovak language and culture – presented to foreign students the specifics of Slovak lexis and their function in speech within the context of intraand interlingual relationships. In her lectures, she helped students to see Slovak as a developped and modern Central European language which has its own genetic and typological properties and as a language capable of reacting to dynamic changes emerging from the communication needs of language users while respecting current trends in European language policy. Klára Buzássyová presented students with the latest results of her linguistic research and discussed the issues regarding the dynamics of vocabulary with an emphasis on the methods of wordformation, motivation, and the impact on the semantic and stylistic value of lexical units. Her papers, published in the Studia Academica Slovaca proceedings from 1980 to 2001 presented her scientific orientation and became an inspiration for the linguistic and didactic conception of Slovak as a foreign language in the context of the development of Slovak studies in Slovakia as well as abroad.
Preliminary studies on the use of Fenton reagent to reduce pollution from wastewater from the production of household chemicals
Authors: Malarski Maciej , Czajkowska Justyna , Nowak Piotr 
Published: March 2019

Abstract
Industrial sewage from the production of household chemicals contain large amounts of impurities in the form of ionic and non-ionic surfactants, detergents, active extenders, enzymes. The mixture of these components means that the reduction of pollutants from this type of waste-water is very burdensome. The article presents the results of preliminary laboratory tests of the possibility of using Fenton reaction in the reduction of pollution in wastewater from the household chemistry industry. The reduction of impurities was determined by the concentration of COD. The tests were carried out on samples of wastewater taken from an industrial wastewater treatment plant from the production of household chemistry. A pollution reduction of 24.7–32.3% was achieved. On the basis of the preliminary tests carried out, the need to better match the doses of reagents to carry out pollution reduction was determined. Despite obtaining values exceeding the limit values for introducing this type of sewage into the sewage system and into the environment, the conducted tests can be considered as prognostic. To compare the process carried out on industrial waste-water, a reduction of impurities was carried out using the Fenton reagent in the standard phenol solution.
An Analysis of the Effectiveness of Interest Rates to Facilitate Price Stability and Economic Growth in South Africa
Authors: Meyer Danie Francois , Chipeta Chama , Camel Richard Thabang Mc 
Published: March 2019

Abstract
Price stability supports accelerated economic growth (GDP), thus the main objective of most central banks is to ensure price stability. The South African economy is experiencing a unique monetary policy dilemma, where a high inflation rate is accompanied by high interest rates and low GDP. This is an unconventional monetary policy scenario and may hold strenuous repercussions for the South African economy. This dilemma was held as the rationale behind this study. The study investigated the effectiveness of the use of the repo rate as an instrument to facilitate price stability and GDP in South Africa. Long-run, short-run and casual relationships between interest rates, inflation and GDP were therefore analyzed. The methodology is based on an econometric process which included a Johansen co-integration test, with a Vector Error Correction model (VECM). Casual relationships were also tested using Granger causality tests. Results of the Johansen Co-integration test indicated the presence of co-integrating long-run relationships between the variables and a significant and negative long-run relationship between the repo rate and inflation rate was revealed, whereas GDP and inflation rate exhibited a significant and positive long-run relationship. The study also found short-run relationships between inflation and GDP, but not for inflation and the repo rate. Further areas of potential research may fixate towards the assessment of other significant alternative policy tools which may be utilized by various countries’ monetary policy authorities to influence supply specific inflationary pressures led by the cost-push phenomena, especially in the short-run.

We generalize approach presented in [Eymard, R.—Handlovičová, A.—Mikula, K.: Study of a finite volume scheme for regularised mean curvature flow level set equation, IMA J. Numer. Anal. 31 (2011), 813–846] and apply it in the field of image segmentation. The so called regularised Riemannian mean curvature flow equation is presented and the construction of the numerical scheme based on the finite volume method approach is explained. The principle of the level set, for the first time given in [Osher, S.—Sethian, J. A.: Fronts propagating with curvature-dependent speed: Algorithms based on Hamilton-Jacobi formulations, J. Comput. Phys. 79 (1988), 12–49] is used. Based on the ideas from [Eymard, R.—Handlovičová, A.– –Mikula, K.: Study of a finite volume scheme for regularised mean curvature flow level set equation, IMA J. Numer. Anal. 31 (2011), 813–846] we prove the stability estimates on the numerical solution and the uniqueness of the numerical solution. In the last section, there is a proof of the convergence of the numerical scheme to the weak solution of the regularised Riemannian mean curvature flow equation and the proof of the convergence of the approximation of the numerical gradient is mentioned as well.
Is Differential Evolution Rotationally Invariant?
Authors: Zámečníková Hana , Einšpiglová Daniela , Poláková Radka , Bujok Petr 
Published: March 2019

Abstract
In this paper, we study a problem of the control parameter settings in Differential Evolution algorithm and test a novel variant of the algorithm called CoBiDE. Although Differential Evolution with basic setting (i.e., CR=0.5; F =0.5) works quite well, it starts to fail on rotated functions. In general, we want to improve the convergence of algorithm primarily on rotated functions. It is done by adapting crossover parameter CR whereas parameter F is fixed to 0.5. There is a recommendation to set CR = 1 for rotated functions. It means that trial vectors are essentially composed from mutant. However, it is not easy task to set the parameters appropriately for solving optimization problem but it is crucial for obtaining good results. Moreover, the quality of points produced in evolution is highly affected by the coordinate system. In CoBiDE, the authors proposed a new coordinate system based on the current distribution of points in the population. We test these two approaches by running both algorithms on six pairs of rotated and non-rotated functions from CEC 2013 benchmark set in two levels of dimension space. This experimental study aims to reveal if such algorithm’s setting is invariant under a rotation.
