Publication Date: 2020-09-23
Volume: Unknown
Issue: Unknown
Page Range: 553-562
Description:
The paper discusses artifacts of Royal (Coronation) Robe (Casula) of St Stephen of Hungary concerning the picture of the St Cement (Clemens) and Constantine Porphyrogenitus on the Holy Crown in the style of the Macedonian Renaissance representing noetic and pneumatic experiences renewing the traditional Christian interpretations. Here the main purpose of the paper upon the fascinating Artifact is the explanation of the historical and structural background in the old Greek noetic and mystical Israelite-Judaic pneumatic tradition for the new kind of the Christian Asterisk-disc eucharistic liturgy, here using the known patterns of Phanes Mythologems.

Analyzing employee behavior related questionnaires by combined fuzzy signature model
Publication Name: Fuzzy Sets and Systems
Publication Date: 2020-09-15
Volume: 395
Issue: Unknown
Page Range: 254-272
Description:
The evaluation of data obtained from responses given to questionnaires in humanities and social sciences, such as management, linguistics, etc. is a complex task with the necessity of dealing with the inherent subjectivity and vagueness in such data. In this paper, a method based on fuzzy signatures (FSigs), suitable for analyzing questionnaires with hierarchically connected (partially) vague responses is proposed, and its applicability will be demonstrated by a real life problem; the partial analysis of an ongoing research examining employee behavior in various companies. The linkage of the factors hidden in the data bases obtained from the answers to the questionnaires, containing various factors interconnected in a more or less tight way, are represented by a hierarchical FSig system, allowing further evaluation and the discovery of emerging connections and deeper patterns among the responses, thus extending the idea of the original FSig model towards a more general, fuzzy-fuzzy signature approach. The method proposed here is a combination of some statistical elements with the Fuzzy Signature model, and it also uses Kohonen-maps in order to discover deeper structural components in the data pool. As FSigs are suitable to express hierarchically structured connections among vague and imprecise features of the individual data, the statistical analysis helps reveal the degrees of redundancies and the closeness of connectedness of the individual elements within the responses, and thus enable the construction of a relevant FSig tree graph for the data on hand, while further expert domain knowledge helps with determining the proper fuzzy aggregations in the intermediate nodes of the FSigs. The case study presented is based on data obtained from North Lithuanian companies. The results of the case study focusing on the analysis of the connection between OCB and CWB, and other factors, disclose some interesting and, partly unexpected, results. They indicate a strong and unambiguous relationship between career satisfaction and OCB, which is not very surprising. However, it is found that there is no relationship with gender, age, and actual position in the company, which are generally supposed to be determining factors. These results may be further validated by expert knowledge, and thus the new combined method for evaluating structured multicomponent data and internal dependencies is adequate.

Constrained ordered weighted averaging aggregation with multiple comonotone constraints
Publication Name: Fuzzy Sets and Systems
Publication Date: 2020-09-15
Volume: 395
Issue: Unknown
Page Range: 21-39
Description:
The constrained ordered weighted averaging (OWA) aggregation problem arises when we aim to maximize or minimize a convex combination of order statistics under linear inequality constraints that act on the variables with respect to their original sources. The standalone approach to optimizing the OWA under constraints is to consider all permutations of the inputs, which becomes quickly infeasible when there are more than a few variables, however in certain cases we can take advantage of the relationships amongst the constraints and the corresponding solution structures. For example, we can consider a land-use allocation satisfaction problem with an auxiliary aim of balancing land-types, whereby the response curves for each species are non-decreasing with respect to the land-types. This results in comonotone constraints, which allow us to drastically reduce the complexity of the problem. In this paper, we show that if we have an arbitrary number of constraints that are comonotone (i.e., they share the same ordering permutation of the coefficients), then the optimal solution occurs for decreasing components of the solution. After investigating the form of the solution in some special cases and providing theoretical results that shed light on the form of the solution, we detail practical approaches to solving and give real-world examples.

Genetic parameters of birth weight trait in dromedary camels (Camelus dromedarius)
Publication Name: Tropical Animal Health and Production
Publication Date: 2020-09-01
Volume: 52
Issue: 5
Page Range: 2333-2340
Description:
Birth weight data of dromedary calves from the database of one of the world’s largest dairy herds (Dubai, UAE) were analyzed for the period from 2007 to 2018. The assessment included the data of 4124 camel calves that were classified into six ecotypes (Emirate, Emirate crossed, Black, Pakistanian, Saudi-Sudanian, and Saudi crossed). The aim of the study was to describe the heritability of birth weight of calves and the breeding value of sires. Genetic parameters of birth weight were estimated by ANOVA model and two BLUP animal models as well. The mean value of the camel calves’ birth weight was 34.75 ± 5.67 kg. The direct heritability of birth weight (h2d = 0.09 ± 0.04–0.11 ± 0.03) was rather low, so was the maternal heritability (h2m = 0.23 ± 0.10–0.50 ± 0.06). The maternal effect from environmental origin (c2 = 0.23 ± 0.08) far exceeded the results previously calculated in cattle. There was no difference in reliability between BLUP1 and BLUP2 models, and both of them were more accurate than the ANOVA model. Based on the results of this study, we conclude that the birth weight of dromedary calves was more influenced by the dam’s intrauterine rearing capacity and by the environment, management, and feeding of the pregnant female camels than the hereditary growth potential. Considerable differences were found among male dromedaries in their breeding values for the birth weight trait.

Blockchain as a driver for smart city development: Application fields and a comprehensive research agenda
Publication Name: Smart Cities
Publication Date: 2020-09-01
Volume: 3
Issue: 3
Page Range: 853-872
Description:
The term “Smart City” denotes a comprehensive concept to alleviate pending problems of modern urban areas which have developed into an important work field for practitioners and scholars alike. However, the question remains as to how cities can become “smart”. The application of information technology is generally considered a key driver in the “smartization” of cities. Detailed frameworks and procedures are therefore needed to guide, operationalize, and measure the implementation process as well as the impact of the respective technologies. In this paper, we discuss blockchain technology, a novel driver of technological transformation that comprises a multitude of underlying technologies and protocols, and its potential impact on smart cities. We specifically address the question of how blockchain technology may benefit the development of urban areas. Based on a comprehensive literature review, we present a framework and research propositions. We identify nine application fields of blockchain technology in the smartization of cities: (1) healthcare, (2) logistics and supply chains, (3) mobility, (4) energy, (5) administration and services, (6) e-voting, (7) factory, (8) home and (9) education. We discuss current developments in these fields, illustrate how they are affected by blockchain technology and derive propositions to guide future research endeavors.

Renaming States—A Case Study: Changing the Name of the Hungarian State in 2011. Its Background, Reasons, and Aftermath
Publication Name: International Journal for the Semiotics of Law
Publication Date: 2020-09-01
Volume: 33
Issue: 3
Page Range: 899-927
Description:
A provision of the Hungarian constitution, adopted in 2011, has renamed the state. The name changed from the Republic of Hungary to Hungary, while the form of the state has remained “republic”. The purpose of this study is to explore the meaning, significance, and several consequences of this provision. The analysis consists of three main parts. The first one gives a general overview of the functions of the names of states. It claims that not only names but also changing or modifying names of states—taking place either by name-giving or by shaping convention—can serve certain functions. The second part focuses on the historical and constitutional details of renaming the Hungarian state, and summarizes the legal context that provided the framework for the 2011 renaming. The third part outlines the arguments for the change, takes a look at the official justification and actual reasons, and reveals some of the consequences of the name change in the past decade. The main contention of the paper is that the renaming of the Hungarian state that took place in 2011 lacked any overt and reasonable justification, and is best explained as an expression of anti-republican sentiment, which indicated, and partly paved the way for the transition into a kind of an authoritarian regime. Finally, the study raises a possible interpretation of the renaming of the Hungarian state in 2011, the point of which is that it adumbrated many later changes in public law and political systems.

Taxonomic analysis of the diversity in the level of wind energy development in european union countries
Publication Name: Energies
Publication Date: 2020-09-01
Volume: 13
Issue: 17
Page Range: Unknown
Description:
In this paper, the development of the wind energy sector in 28 European Union countries in 2017 is described. By means of taxonomic methods-i.e., Ward's method and the Wroclaw taxonomic methods-clusters of countries similar in terms of their potential and level of development of the wind energy sector in the EU are distinguished. The main purpose of the paper is to separate and cluster EU countries due to the current development potential of the wind energy sector and determinants stimulating the development of this sector. By means of the ranking methods of linear ordering (Technique for Order of Preference by Similarity to Ideal Solution-TOPSIS method), a ranking of EU countries that defines their position in the development of this very important wind energy sector was determined. The results show that the research hypothesis of a great diversity of EU countries considering the development potential of the wind energy sector is justified. The countries of the former European Union, which have focused for a long time on the development of wind energy in their energy policy and have had favorable climate and natural conditions, as well as a large social acceptance of programs supporting the acquisition of energy from renewable sources, have primacy in the development ranking of the energy sector. Additionally, new members of the union, in spite of some delays associated with the development of "green"energy, are trying to increase their energy potential in this area. The research may be extended to include further analyses regarding other renewable energy sources and take into account other European and world countries.

Model-based control algorithm development of induction machines by using a well-defined model architecture and rapid control prototyping
Publication Name: Electrical Engineering
Publication Date: 2020-09-01
Volume: 102
Issue: 3
Page Range: 1103-1116
Description:
This paper presents a new control algorithm development approach for induction machines by using model-based design and a systematically built model architecture implemented in MATLAB/Simulink. The model architecture follows a three-layer structure, and it is developed according to the principle of functional decomposition and the needs of reusability and expandability. The first model layer consists of elementary model and algorithm components, the second contains a machine simulation model and a field-oriented control (FOC) algorithm, built upon the first layer’s components, and the third realises the executable models by connecting the models and algorithms defined in the second layer. Furthermore, rapid control prototyping (RCP) is discussed as an experimental validation method, and an experimental setup with RCP is also introduced. The application of the presented methods is demonstrated by simulations as well as by experiments, and by using a control algorithm based on FOC as an example.

Servitization of public service processes with a simulation modelling approach
Publication Name: Engineering Management in Production and Services
Publication Date: 2020-09-01
Volume: 12
Issue: 3
Page Range: 116-131
Description:
This article aims to examine how the theory of co-production can be connected with servitization and digitalisation and used together for the public service development with the help of discrete-event simulation modelling to highlight time-related deficiencies of a complex public service process, which is most commonly used by patchwork families. Data was taken from the Guardianship Office in Gyor (Hungary), based on which in-depth interviews were conducted. Based on the legal background and the interviews, the authors of the article created the process model of the contacting procedure. Based on the model, discrete-event simulation was used to identify the process elements for potential improvement through servitization. Discrete-event simulation showed the insufficiency of national regulation regarding the whole process and weaknesses of the contacting procedures in terms of quality and success. Basic reasons were found for the dissatisfaction expressed by participants of the procedures (administrators and customers). The increasing customer demand for high quality and efficient public services and failures in the New Public Management (NPM) in Eastern European countries require other approaches to advance. The paper connects the theory of co-production and servitization in a public service context and demonstrates how a complex public service can be examined with this approach to find possible improvements. The government must change the process regulation considering the number of the cases, the workload of administrators and family types (divorced or patchwork). The emphasis should be placed on the training and experience of administrators.
