Abstract

BRLO-Tree (Block-R-Tree-Loose-Octree) is presented in this paper based on the R-Tree and Loose-Octree. The aim of the structure is to visualize the large scale and complex dynamic scenes in a 3D (three-dimensional) GIS (Geographic Information System). A new method of clustering rectangles to construct R-tree based on an improved K-means algorithm is put forward. Landform in 3D GIS is organized by R-Tree. The block is used as the basic rendering unit. The 3D objects of each block are respectively organized by a Loose-Octree. A series of techniques, based on this data structure, such as LOD (Level of Detail), relief impostors are integrated. The results of the tests show that BRLO-Tree cannot only support the large scale 3D GIS scene exhibition with wandering and fighting, but it can also efficiently manage the models in a dynamic scene. At the same time, a set of integrated techniques based on BRLO-Tree can make the rendering pictures more fluence and the rendering time vastly improved.

Mieke Bal and Rachel E. Burke

Abstract

After Rachel E. Burke briefly introduces the essays presented with a focus on our contemporary relationship to modern subjectivity, Mieke Bal will make the case for the sense of presentness on an affective and sensuous level in Munch’s paintings and Flaubert’s writing by selecting a few topics and cases from the book Emma and Edvard Looking Sideways: Loneliness and the Cinematic, published by the Munch Museum in conjunction with the exhibition Emma & Edvard. It is this foregrounded presentness that not only produces the ongoing thematic relevance of these works, but more importantly, the sense-based conceptualism that declares art and life tightly bound together. If neither artist eliminated figuration in favour of abstraction, they had a good reason for that. Art is not a representation of life, but belongs to it, illuminates it and helps us cope with it by sharpening our senses. As an example, a few paintings will clarify what I mean by the noun-qualifier “cinematic” and how that aesthetic explains the production of loneliness.

Summary

In the years 2017-2018 the Marketing Faculty of Łódź University conducted a research project “Marketing strategies of companies based in Łódź Voivodeship on foreign markets”. The aim of this text is to present the initial research findings strategies implemented by surveyed companies on foreign markets. The examined companies seldom attempted to conduct the foreign market research and the marketing strategy that they used was strictly related to the prevailing form of expansion into foreign markets, i.e. export. Both the product and the pricing policy were adapted to the specific character of the foreign market. Activities in the area of distribution were limited to indirect export and they were not initiated by the examined companies. The prevailing majority of companies used the Internet, trade fairs and exhibitions in their promotional activities. The intermediaries in the distribution channel were responsible for subsequent promotional activities. They involve marketing strategies typical for small and medium companies and their content depends on the intermediaries in the distribution channel on foreign markets.

Abstract

The paper presents selected results of the work carried out at the Air Force Institute of Technology (AFIT) in the scope of computer diagnostic tests of the SWPL-1 Cyklop helmet mounted flight parameters display system. This system has been designed in such a way that it warns the pilot of dangerous situations occurring on board the helicopter and threatening the flight safety (WARN) or faults (FAIL), which inform about a failure in given on-board equipment. The SWPL-1 system has been awarded the Prize of the President of the Republic of Poland during the 17. International Defense Industry Exhibition in Kielce.

Abstract

Significant changes started in the children’s books market from 1989. The market gradually began to be saturated with far less expensive reprints of Western productions. Their artistic form is based on the style of cartoons, thus replacing the diversity of illustrations which is necessary to activate the development of child’s perception. Consequently, a special role is played by measures aimed to popularize the artistic achievements of artist-illustrators and designers of books for children in Poland. After the political system transformation, earlier activities were continued (plein-air workshops for illustrators in the Roztocze region). New undertakings were also initiated (meetings with graphic layout artists, conferences, exhibitions, workshops for children and teenagers in libraries). The article discusses the activities of Gallery [Galeria] 31 at Branch no. 30 of Hieronim Lopaciński City Public Library in Lublin, Poznań Trade Fair Meetings in Poznań, and plein-air workshops for artist-illustrators. These events are an example of local and nation-wide activities. They develop a conscious attitude towards the impact of the book form as a visual communication. The forms of Polish books (including textbooks and reading list books) for the youngest readers cannot be regarded as satisfactory.

Abstract

In 2017, the National Museum commemorated the bicentenary of the discovery of the Manuscript of Dvůr Králové and the Manuscript of Zelená Hora by further material research into both works and especially by an exhibition of their originals. The main aims of this research into the manuscripts included the documentation and evaluation of their current physical condition and the mapping of the effect of the microchemical analyses performed in the context of the disputes over the authenticity of the manuscripts between the middle of the 19th century and the 1970s. For the achievement of these objectives, a detailed documentation of all the pages of the manuscripts in different types of lighting (visible direct, lateral, transmitted, ultraviolet, infrared), optical microscopy, and the identification of the degradation productions of damaged places by means of X-ray fluorescence analysis and Raman spectroscopy were used. This provided new information on the current physical condition of the manuscripts and documentation of the damage caused by historical microchemical testing. In addition, some previously unpublished historical tests were identified, thus offering a new perspective on some current damage of the two manuscripts.

Abstract

In June of 1892, Smetana’s Prodaná nevěsta (The Bartered Bride) was heard in Vienna for the first time as part of a guest appearance by the Czech National Theatre at the International Musical and Theatrical Exhibition. The clear success of the opera and of the performances of the National Theatre ensemble was reflected in the reviews of the Viennese critics, who were calling for German-language performances of Prodaná nevěsta on the stage of the Court Opera. On the basis of information from the archives of the Court Opera (Haus-, Hof- und Staatsarchiv), one can document the reasons why, as it turned out, the first Viennese (and German-language) stage to produce the opera was the Theater an der Wien in April 1893, and why the premiere at the Court Opera did not occur until three years later. The study also devotes attention to the first performers for both productions of Prodaná nevěsta and to the circumstances of the two Viennese premieres, which opened up the pathway to other stages around the world after a thirty-year delay.

Abstract

This paper investigates the link between cluster membership and performance of clustered companies. The object of the study is the Croatian Wood Cluster (CWC). The paper presents the results of a survey of 34 members of the Croatian Wood Cluster operating in wood and furniture industries. The survey was conducted in order to identify and analyse perceptions and attitudes of CWC members towards CWC objectives, activities and performance; the cooperation strength among cluster members and that with the players outside the cluster; the effects of clustering on the operational performance of the clustered SMEs; business and economic setting in Croatia, barriers for the work of the CWC and the relevancy of government policy measures. The empirical results indicate that the economic performance of the clustered companies is significantly predicted by the cooperation with public institutions, financial institutions and professional associations (such as the Agency for Investments and Competitiveness) provided by the CWC and by the access to cluster resources such as horizontal cooperation, fairs, exhibitions etc. Additionally, an access to credit, customers and competitors shows a significant positive effect on finance-based performance of the clustered companies. On the other hand, cooperation among cluster members and cooperation with scientific, high education and research institutions show no significant relationship with the company performance.

Abstract

The article focuses on the life and work of Božena Jelínková-Jirásková (1880–1951), which are described and interpreted by means of a content analysis of her correspondence and artistic production. It presents the basic phases in the artist’s life and work in terms of the influence of her father, the writer Alois Jirásek, and subsequently her husband, the diplomat and writer Hanuš Jelínek. The study provides a chronological overview of the course of her education, life in Paris, exhibition activities, social contacts and artistic movements that affected her paintings. In this respect, a source of inspiration for the work of Jelínková-Jirásková can mainly be seen in the work of Paul Cézanne and Otakar Kubín, with the latter of whom she maintained long-term contacts. The central motif of their work was a landscape, comprising not only a major theme of her artistic production, but also a form of search for personal identity, internal security and a familiar home. A partial objective of the article is to cover the artistic development of Jelínková-Jirásková from Impressionism to realistic and figural work, her subsequent inclination to Neoclassical landscape painting and eventually a return to Realist painting, the Czech landscape and still lifes. The article presents Jelínková-Jirásková as one of the first Czech professional painters to have achieved recognition in both Czechoslovakia and France.
