Radoslav Lacko Supervisor: Mgr. Petr Polák MSc. Academic Year: 2018/2019 Abstrakt Skúmanie cenovej citlivosti dopytu po palivách je populárnou témou medzi výskumníkmi. Cenová elasticita sa používa na predpovedanie daňových príj- mov ale aj spotreby paliva za rôznych okolností. Práca sa zameriava na odhad elasticity pre Českú republiku s použitím vysoko frekvenčnych dát. České dáta boli získané procesom data miningu. Pozorovaná elasticita sa líši podľa úrovne agregácie dát. Odhadnutá dlhodobá elasticita bola medzi −0.38 a −0.68 pre použivateľov benzínu a medzi −0.43 a −0.54 pre dieselových použí- vateľov. Odhadnutá krátkodobá elasticita bola omnoho nižšia, čo potvrdzuje ekonomickú teóriu.

Textile waste in the context of the circular economy
No full textThe concept of a circular economy is built in opposition to the traditional linear model where raw materials are used, things are created from them, they are consumed and the leftovers are thrown away. This model relies on large quantities of cheap and accessible materials and energy sources. The textile sector is part of the economies meeting the requirements of the circular economy. What is the real place and importance of waste from textile production and their role for the circular economy, determine the relevance and arouse the interest of the authors in the research. The objective of this paper is to provide a comprehensive overview of the existing situation and to study the textile waste in the context of the circular economy. For the goal fulfillment we use the descriptive-analytical method - theoretical aspects of the studied scientific field are investigated on the basis of current literature research. The information collected is summarized and analyzed; systematic approach; analytical approach; study of the works of authors in the field; comparative analysis; method of observation; determination of relative shares. Current scientific research and economic aspects about textile waste in the context of the circular economy have been explored. The various author collectives work in the field of textile waste, its management and its connection with the circular economy. Research in the field of textiles shows the great importance and fundamental role of textile waste for the realization of the circular economy concept
2011 Annual Health Physics Report for the HEU transparency Program
Get PDFDuring the 2008 calendar year, Lawrence Livermore National Laboratory (LLNL) provided health physics support for the Highly Enriched Uranium (HEU) Transparency Program for external and internal radiation protection. They also provided technical expertise related to BDMS radioactive sources and Russian radiation safety regulatory compliance. For the calendar year 2008, there were 158 person-trips that required dose monitoring of the U.S. monitors. Of the 158 person-trips, 148 person-trips were SMVs and 10 person-trips were Transparency Monitoring Office (TMO) trips. There were 6 monitoring visits by TMO monitors to facilities other than UEIE and 8 to UEIE itself. There were three monitoring visits (source changes) that were back-to-back with a total of 24 monitors. LLNL's Hazard Control Department laboratories provided the dosimetry services for the HEU Transparency monitors. In 2008, the HEU Transparency activities in Russia were conducted in a radiologically safe manner for the HEU Transparency monitors in accordance with the expectations of the HEU Transparency staff, NNSA and DOE. The HEU Transparency now has thirteen years of successful experience in developing and providing health and safety support in meeting its technical objectives
Visualization and verification of plans
No full textTitle: Visualization and Verification of Plans Author: Radoslav Glinský Department: Department of Theoretical Computer Science and Mathematical Logic Supervisor of the bachelor thesis: Doc. RNDr. Roman Barták, Ph.D. Abstract: Plan analysis is an important part of complete planning systems. In order to make even larger plans transparent and human readable, we have developed a program which helps users with the analysis and visualization of plans. This program is called VisPlan - Interactive Visualization and Verification of Plans. VisPlan is an inevitable part of this thesis as it practically implements its plan verification and visualization solutions. VisPlan finds and displays causal relations between actions, it identifies possible flaws in plans (and thus verifies plans' correctness), it highlights the flaws found in the plan and finally, it allows users to interactively modify the plan and hence manually repair the flaws or just fine-tune the plan.

Were king Stefan the First-Crowned and his son Radoslav co-rulers?
Get PDFThe Serbian historiography considers the issue of the co-ruling of King Stefan the First-Crowned and his son Radoslav as the one finally resolved. The suggested solution on the co-rule of Stefan and Radoslav may be most succinctly expressed as following: as early as in the year of 1220, due to the frail health of Stefan the First-Crowned and Radoslav's marriage to Anne the Epirus princess, Radoslav was crowned to be the king and positioned to co-rule with his father after the Byzantine model of governing. Nevertheless this point of view has some loose ends. The notion of co-ruling and the very term of 'co-ruler' are quite freely used in the scholarly works. A general consensus on the precise meaning has not been reached yet. At the point where one author perceives a co-rule, the other categorically denies it. Basically the approach equalizing the heir to the throne and the co-ruler is wrong. Although the co-rulers in most cases were the throne heirs, they cannot be called the co-rulers because of the right to inherit the throne, but for the ruling attributes that formally established that right. The conviction of the co-rule of King Stefan and his son Radoslav is founded on the interpretation of the facts coming from the following sources: entitling charters for the monastery of Žiča, produced by Stefan and Radoslav around 1220; some segments from St. Sava's biographies by Domentian and Theodosius describing the circumstances of Stefan's death-bed leaving the throne to Radoslav; the three acts of the town of Kotor from 1221 and 1227 dated by the rule of king Radoslav, the portraits of Stefan and Radoslav next to the entrance to the Church of the Ascension in the monastery of Žiča and in the nartex of the Mileševa monastery church. In the first Žiča charter, Stefan calls Radoslav his heir, while in the second Žiča charter Stefan points out Radoslav as his first-born son blessed by him to be the king of the whole state. (jegože i blagoslovismo biti emou kralju v'se sije dr'žave). Though differently in manner, Radoslav's hereditary right has been emphasized in both of these charters. In my opinion, the formulation of the second charter does not refer to the coronation of a co-ruler, but a ceremonious act of proclaiming the successor. That may have been one of the results of Radoslav's marrying Anne the daughter of the Epirus ruler Theodore I Angelos in 1219/1220. St. Sava's biography by Domentian tells us about Stefan's appointing Radoslav for his heir immediately before his death. That was followed by arch-bishop Sava's crowning him the king to be s'prestol'nik' ot'č'stva svoego. The expression s'prestol'nik' was supposed to be the proof of Radoslav being his father's co-ruler. However, Domentian uses the term s'prestol'nik' ot'č'stva svoego in the metaphysical sense to cast the stress on the Nemanjić dynastic permanent right to the Serbian throne, not to describe the relations in the real time. The Nemanjić hereditary authority was regarded equal to the throne, so every ruler stepping onto it, according to Domentian, shares the same throne with his predecessors and the future rulers from the same family. Domentian calls both Stefan the First-Crowned and Vladislav, Radoslav's brother s'prestol'nik' ot'č'stva svoego, and the two of them have been firmly confirmed not to be their fathers' co-rulers. Besides, Domentian speaks of Radoslav as of s'prestol'nik' at the moments immediately preceding Stefan's death, thus not even for the chronological reasons can this fact be used as an evidence for the co-rule of Stefan and Radoslav. Theodosius similarly depicts the shift on the throne using the word s'prestol'nik' in the same context. The two acts of the town of Kotor from 1221 and the one from 1227 were dated sub tempore domini regis Radoslavi. The mentioning of king Radoslav at the time when his father was the Serbian king was considered a valid proof of Radoslav's co-rule with his father with the title of a king. Anyway, this is not about the mere mentioning of king Radoslav in some document, but about the official Kotor town documents being dated after the rule of king Radoslav as the master of Kotor (dominus rex). The Kotor town resolutions were dated in the same fashion at the time when Stefan Nemanja's son Vukan had the rule over Duklja while his father and afterwards his brother held the Serbian throne. Therefore, the mentioning of king Radoslav as the master of Kotor means that he got Duklja to rule probably as an heir to the throne and, like Vukan, he took over the old royal title of Duklja. To the left and to the right from the entrance to the Žiča monastery Church of the Ascension, the portraits of King Stefan the First-Crowned and king Radoslav were painted. The portraits were believed to have been made at the time of Stefan and Radoslav's producing the charter to the monastery of Žiča (circa 1220), so Radoslav's royal title in the inscription next to the portrait was taken as evidence that he had already been appointed as his father's co-ruler and the king. Nonetheless, the Žiča exonartex with the tower was built most likely during the rule of king Radoslav (circa 1229-1234); hence the portrait itself could have been painted only then implying that the title in the inscription next to the character of Radoslav might have referred to his independent status as a ruler. In addition to this, there is an iconographic motif after which, when the son is to carry on the father's building project, the younger, i.e. the other founder is always portrayed on the left side of the entrance, just like in the case of Žiča. A donors' composition, including the portraits of Stefan the First-Crowned and Radoslav, was painted in the Mileševa church nartex during the twenties of the 13th century. Both Stefan and Radoslav bear the wreaths on their heads and Stefan holds a scepter in his left hand. The wreath on Radoslav's head is regarded as a symbol of his keeping the position of a co-ruler. Still without the support of the written sources, for which this article has showed that they do not prove Radoslav's co-rule, the portraits in Mileševa do not have an independent source value. We do not have at our disposal a representative sample from an earlier period or the one contemporary with the Mileševa fresco paintings to serve as the basis for establishing the iconographic patterns of presenting the co-ruling position. Certain examples of the later paintings (Sopoćani, Bogorodica Ljeviška) indicate that the images of the heirs with the ruling signs do not mean that their actual coronation and raising to the rank of a co-ruler had already taken place. Not even the portraits of the younger king Uroš, i.e. king Uroš at the time of Dušan's imperial rule mark the co-ruler, but the heir to the throne. Since painting is the ultimate expression of the monarchic ideology, the painters of the donors' compositions, similarly to the biographers, have no need to convey every particularity from the real life. Instead of that, they primarily use symbols. Therefore, the crown on the head of the ruler's son doesn't necessarily have to imply him being crowned and set to be a co-ruler. The wreath on Radoslav's head only symbolized his position of the throne heir. From my point of view, no source analyzed here provides an unequivocal confirmation of Radoslav's co-rule. If his participation in the governing may be spoken of, it has been achieved only over the position of the king of Duklja. Considering the fact that the sources of the co-ruling matter are scarce and subject to various interpretations, this piece of work has been intentionally titled with a question mark. Its purpose is not to offer the final and consistently opposite solutions from those generally accepted by scholars, but to provoke a further scientific dispute on this sensitive issue

Estetika okraja a hranice (K vybraným aspektom fenoménov okraja a hranice v slovenskej literatúre 20. storočia v stredoeurópskom kontexte)
Get PDFRadoslav P a s s i a Aesthetics of Periphery and Border (To Selected Aspects of Periphery and Border Phenomenon in Slovak Literature of the 20th Century in Central European Context) Abstract The dissertation deals with selected aspects of periphery and border phenomenon in Slovak literature of the 20th century in Central European context. In the preliminary chapter Border the author focuses particularly on selected texts by Central European writers which are thematically set in the Eastern Carpathians. This radically multiethnic region is considered to be one of the relatively independent cultural areas of Central Europe by the author. Narrative perspectives of a stranger, outcast, migrant in combination with the themes of border and conflict between vernacular and alien are characteristic for the literary image of the Eastern Carpathian border area in the 20th century. The author looks at the way the literary appearance of this area is ideologically deformed in the works of individual authors. The writers (mainly Czech and Polish) who do not come from the Eastern Carpathian border area use characters of strangers to reflect on the relationship between the modern and the traditional. Autochthonous authors often make use of the stranger characters to depict the area's self-colonial efforts in relation to the...Radoslav P a s s i a Estetika okraja a hranice (K vybraným aspektom fenoménov okraja a hranice v slovenskej literatúre 20. storočia v stredoeurópskom kontexte) Abstrakt Táto dizertačná práca sa venuje vybraným aspektom fenoménov okraja a hranice v slovenskej literatúre 20. storočia v stredoeurópskom kontexte. V úvodnej časti Hranica autor analyzuje niektoré texty stredoeurópskych autorov, ktoré sú tematicky zasadené do prostredia východných Karpát. Tento multietnický región je jedným z relatívne nezávislých kultúrnych areálov strednej Európy a je charakterizovaný unikátnou kombináciou hraničných izoglos geografického, jazykového a kultúrneho charakteru. Autor považuje za jeden z charakteristických prvkov literárneho zobrazenia východokarpatského hraničného areálu v 20. storočí naratívnu perspektívu cudzinca, vyhnanca alebo prisťahovalca v kombinácii s témami hranice a konfliktu medzi domácim a cudzím. Autor opisuje aj základné ideologické konštanty spojené s literárnym zobrazením tohto areálu. Spisovatelia (najmä českí a poľskí), ktorí nepochádzajú z východokarpatského hraničného areálu využívajú postavy cudzincov predovšetkým na reflexiu vzťahu medzi moderným a tradičným. V prózach autochtónnych autorov sa prostredníctvom postáv cudzincov často zobrazuje sebakolonizačné kultúrne úsilie areálu vo vzťahu k...Institute of Slavonic and East European StudiesÚstav slavistických a východoevropských studiíFilozofická fakultaFaculty of Art
