Petro Shelest (1908–1997), the First Secretary of the Communist Party of the Ukrainian Soviet Socialist Republic and a member of the Politburo of the Central Committee of the Communist Party of the Soviet Union, was one of the strongest advocates of an armed invasion of Czechoslovakia among Soviet leaders in 1968. The Soviet leadership tasked him to maintain contacts with the so-called healthy forces in the Communist Party of Czechoslovakia; in the beginning of August, Secretary of the Central Committee of the Communist Party of Czechoslovakia Vasil Biľak (1917–2014) secretly handed over to him the notorious “letter of invitation” in public lavatories in Bratislava. The author asks a fundamental question whether it is possible to identify a specific Ukrainian factor which stepped into the Prague Spring process and contributed to its tragic end. He attempts to capture Shelest’s position in the decision-making process and describe information that Shelest was working with., To this end, he has made use of reports of the Committee for State Security (Komitet gosudarstvennoi bezopasnosti – KGB) of the Ukrainian Soviet Socialist Republic on developments in Czechoslovakia and reactions thereto among Ukrainian citizens produced in the spring and summer of 1968, which were being sent to Shelest and other Ukrainian leaders. These documents have lately been made available in Ukrainian archives and partly published on the website of the Institute for the Study of Totalitarian Regimes. Their analysis brings the author to a conclusion that they were offering a considerably distorted picture of the situation. Instead of relevant information and analyses, they only present various clichés, ideological rhetoric, inaccuracies, or downright nonsenses. Their source were often members of the Czechoslovak State Security who were often motivated by worries about their own careers and existence and were acting on their own., and The uncritical acceptance of the documents contributed to a situation in which in the leader of the Ukrainian Communists and other Soviet representatives were creating unrealistic pictures of the events taking place in Czechoslovakia, believing that anti-socialist forces were winning, anti-Soviet propaganda was prevailing, and Western intelligence agencies were strengthening their position in Czechoslovakia, and that there was a threat that the events that had taken place in Hungary in 1956 would repeat themselves again. As indicated by his published diary entries and other documents, Petro Shelest was using these allegations both in discussions inside his own party and during negotiations with Czechoslovak politicians. Just like in the case of the leaders of Polish and East German Communists, Władysław Gomułka and Walter Ulbricht, respectively, the principal reason why Shelest was promoting a solution of the Czechoslovak crisis by force was, in the author’s opinion, his fear of “contagion” of his own society by events taking place in Czechoslovakia which the Ukraine shared a border with.
This article builds on the emerging tradition of transnationalism in migration research, which considers both migrants’ ‘making a home’ in their host societies and their continued attachments to their places of origin as parallel processes. It examines the factors that influence migrants’ simultaneous negotiation of ‘belonging’ in the home and host societies. This question is particularly significant in the ‘liquid’ context of free intra-EU mobility. The analysis is based on semi-structured in-depth interviews conducted in 2014–2016 with 41 Czech migrants who had moved to the United Kingdom in 1990–2015. Building on existing research of Central and Eastern European migration, the article shows that despite their diverse trajectories, most interviewees strive for ‘grounded’ lives with a family and a predictable future. Their sense of ‘belonging’ is affected by their reasons for coming to and staying in the UK, but especially by the presence or absence of agency; whether the migrant’s decision to stay was voluntary or dependent. Aspects of the individual’s migration situation and personal characteristics are also shown to structure migrant belonging. The concept of a ‘leap of faith’ is introduced to capture the role of a conscious commitment to settling in the host country, both physically and mentally, and thus re-gaining ‘control’ over one’s migration trajectory in cases when the decision to stay was not made independently.
Ontology is widely used in the computer domain to structure concepts that represent a view of world nowadays, which could formally specify semantic relationship among the terms. In this paper, we present coordination between agent crawlers based on ontology in Topic Specific Search Engines, and we try to measure understanding among them, relying on Formal Concept Analysis (FCA) instead of comparing the terms only. In literature, most papers on concept similarity in FCA are based on two different concepts in the same concept lattice, and whereas there is very little research related to different concept lattices or even different agents. We propose a novel method on concept similarity for computing the Concept-Concept similarity, the Concept-Ontology similarity and the Ontology-Ontology similarity, and at last we can deduce understanding among agent crawlers. Finally, we can guide the crawlers effectively in our Search Engine.
For a nontrivial connected graph $G$ of order $n$ and a linear ordering $s\: v_1, v_2, \ldots , v_n$ of vertices of $G$, define $d(s) = \sum _{i=1}^{n-1} d(v_i, v_{i+1})$. The traceable number $t(G)$ of a graph $G$ is $t(G) = \min \lbrace d(s)\rbrace $ and the upper traceable number $t^+(G)$ of $G$ is $t^+(G) = \max \lbrace d(s)\rbrace ,$ where the minimum and maximum are taken over all linear orderings $s$ of vertices of $G$. We study upper traceable numbers of several classes of graphs and the relationship between the traceable number and upper traceable number of a graph. All connected graphs $G$ for which $t^+(G)- t(G) = 1$ are characterized and a formula for the upper traceable number of a tree is established.

Digital Watermarking (DW) based on computational intelligence (CI) is currently attracting considerable interest from the research community. This article provides an overview of the research progress in applying CI methods to the problem of DW. The scope of this review will encompass core methods of CI, including rough sets (RS), fuzzy logic (FL), artificial neural networks (ANNs), genetic algorithms (GA), swarm intelligence (SI), and hybrid intelligent systems. The research contributions in each field are systematically summarized and compared to highlight promising new research directions. The findings of this review should provide useful insights into the current DW literature and be a good source for anyone who is interested in the application of CI approaches to DW systems or related fields. In addition, hybrid intelligent systems are a growing research area in CI.
The dissociation between egocentric and allocentric reference frames is well established. Spatial coding relative to oneself has been associated with a brain network distinct from spatial coding using a cognitive map independently of the actual position. These differences were, however, revealed by a variety of tasks from both static conditions, using a series of images, and dynamic conditions, using movements through space. We aimed to clarify how these paradigms correspond to each other concerning the neural correlates of the use of egocentric and allocentric reference frames. We review here studies of allocentric and egocentric judgments used in static two- and three-dimensional tasks and compare their results with the findings from spatial navigation studies. We argue that neural correlates of allocentric coding in static conditions but using complex three-dimensional scenes and involving spatial memory of participants resemble those in spatial navigation studies, while allocentric representations in two-dimensional tasks are connected with other perceptual and attentional processes. In contrast, the brain networks associated with the egocentric reference frame in static two-dimensional and three-dimensional tasks and spatial navigation tasks are, with some limitations, more similar. Our review demonstrates the heterogeneity of experimental designs focused on spatial reference frames. At the same time, it indicates similarities in brain activation during reference frame use despite this heterogeneity., Sofiia Moraresku, Kamil Vlcek., and Obsahuje bibliografii
This paper formulates a unit commitment optimization problem for renewable energy sources distributed in a micro-grid formed by a complex of intelligent buildings of both office and residential characters, including a wide range of amenities. We present a general description of the solution of this task using the simulated annealing heuristic optimization technique. The experiment was processed in the specialized computer program. For comparison, Appendix A of the article describes the Lagrange multipliers optimization method as the conventional alternative to the used heuristic technique. A description of the concept of intelligent buildings is provided in Appendix B.
