Opis:
Scene recognition is a paramount task for autonomous systems that navigate in open scenarios. In order to achie ve high scene recognition performance it is necesary to use correct information. Therefore, data fusion is beco ming a paramount point in the design of scene recognition systems. This paper presents a scenery recognition system using a neural network hierarchical approach. The system is based on information fusion in indoor scenarios. The system extracts relevant information with respect to color and landmarks. Color information is related mainly to localization of doors. Landmarks are related to corner de tection. The corner detection method proposed in the pa per based on corner detection windows has 99% detection of real corners and 13.43% of false positives. The hierar chical neural systems consist on two levels. The first level is built with one neural network and the second level with two. The hierarchical neural system, based on feed for ward architectures, presents 90% of correct recognition in the first level in training, and 95% in validation. The first ANN in the second level shows 90.90% of correct recogni tion during training, and 87.5% in validation. The second ANN has a performance of 93.75% and 91.66% during training and validation, respectively. The total perfor mance of the systems was 86.6% during training, and 90% in validation.

Opis:
Composé de quatre poèmes, de longueur variable, Symphonie musicale : pour une poévie de la Vie est un recueil de Jean-Baptiste Fondjo publié en 2022 aux éditions L’Harmattan de Paris. Cette œuvre poétique, essentiellement lyrique, se définit comme un hymne à la vie. Cette vie, si chère au poète, est célébrée à partir de la scène générique de la poévie, comme en témoigne le titre de l’œuvre. Mot-valise forgé à partir du morphème « poé », une troncation de la lexie « poésie » et du terme « vie », la poévie est un art poétique qui vise à promouvoir la vie, en mobilisant divers procédés d’écriture dont les plus représentatifs sont les déictiques, les marques suprasegmentales et la métaphore. Cette stratégie témoigne de la subjectivité du poète. Ces unités énonciatives donnent prise à l’analyse stylistique. Cette dernière se définit, en effet, comme une théorie et une méthode d’analyse structurale qui vise au décryptage et à l’interprétation des ressources langagières mises en œuvre par un écrivain, dans son texte. L’intérêt de cette étude est de montrer comment les outils de la linguistique de l’énonciation se prêtent à une interprétation stylistique de la poésie de Jean-Baptiste Fondjo.
Composed of four poems of varying length, Symphonie musicale: pour une poévie de la Vie is a collection by Jean-Baptiste Fondjo, published in 2022 by L’Harmattan editions in Paris. This poetic work, essentially lyrical, is defined as a hymn to life. This life, so dear to the poet, is celebrated from the generic scene of poévie, as evidenced by the title of the work. A portmanteau word forged from the morpheme “poé”, a truncation of the lexeme “poésie” and the term “vie”, poévie is a poetic art which aims to promote life, by mobilizing various writing processes, the most representative being deictics, suprasegmental marks and the metaphor. This strategy testifies to the subjectivity of the poet. These enunciative units give rise to stylistic analysis. The latter is defined, in fact, as a theory and a method of structural analysis which aims to decipher and interpret the linguistic resources implemented by a writer in his text. The interest of this study is to show how the tools of the linguistics of enunciation lend themselves to a profitable stylistic interpretation in the poetry of Jean-Baptiste Fondjo.

Opis:
The aim of the studies was to design, implement and test the algorithm for vectorization of the scene, which is analyzed by an autonomous robot. The vectorization is the process of extraction of the contours of the objects located in the image taken by a camera. The result is stored in a computer's (robot's) memory as a sequence of points in euclidean space marking the examined objects' corners. During the tests, various images were used. Each one was previously pre-processed in a different way in order to reveal and highlight the contours of the objects. The vectorization process is divided into three steps which are described in detail in this article.

Opis:
We describe an experimental study, based on several million video scenes, of seven keypoint detection algorithms: BRISK, FAST, GFTT, HARRIS, MSER, ORB and STAR. It was observed that the probability distributions of selected keypoints are drastically different between indoor and outdoor environments for all algorithms analyzed. This paper presents a simple method for distinguishing between indoor and outdoor environments in a video sequence. The proposed method is based on the central location of keypoints in video frames. This has lead to a universally effective indoor/outdoor environment recognition method, and may prove to be a crucial step in the design of robotic control algorithms based on computer vision, especially for autonomous mobile robots.

Opis:
Whenever the recording engineer uses stereo microphone techniques, he/she has to consider a recording angle resulting from the positioning of microphones relative to sound sources, besides other acoustic factors. The recording angle, the width of a captured acoustic scene and the properties of a particular microphone technique are closely related. We propose a decision supporting method, based on the mapping of the actual position of a sound source to its position in the reproduced acoustic scene. This research resulted in a set of localisation curves characterising four most popular stereo microphone techniques. The curves were obtained by two methods: calculation, based on appropriate engineering formulae, and experiment consisting in the recording of sources and estimation of the perceived position in listening tests. The analysis of curves brings several conclusions important in the recording practice.

Opis:
The study focuses on the schematization of natural categories of the meaning in the preposition over, and contrasting it with the schematization of relevant spatial relations in Serbian and Ukrainian. Contrasting similar verbalizations of spatial relations in Ukrainian and Serbian has enabled us to conclude that distinct senses of over correlate with image-schemas characteristic for various Ukrainian prepositions – mainly над and через, but also partially за and на, and Serbian prepositions preko and nad. We deduce that in Ukrainian and Serbian the presented set of scenes are not conceptualized as a chain of connected variations derived from the same proto-scene and possessing one or two changes in the scene that provoke a distinct sense, but rather as different scenes that represent various categories of spatial relations, and they are not connected via derivation.

Opis:
The notions of inter- and transdisciplinarity represent categories which the humanities frequently resort to in the discourse, but which remain difficult to define.  The attempts to do so are most often associated with subscribing to one of the possible models of interpreting relationships between individual disciplines of science. Mieke Bal’s concept of transdisciplinarity, which this paper discusses, envisages a framework where the privileged form of formulating scientific concepts would be in research practice that is rooted not only in the methodologies of individual sciences but most of all in the everyday practices and experiences.

Opis:
The article discusses the question of traditional images in Greek epic poetry, which are based on metonymy, coexisting with themes and type-scenes and stabilising the epic song. Firstly, I present a sketch of oral theory, originally presented by M. Parry and A. Lord. Secondly, I deal with the question of the type-scenes in Homeric epics and Russian oral epic songs—the middle element of A. Lord’s oral song structure. After that, I move on to cognitive theory and its application to Homeric epics, especially in the matter of cognitive scripts as a basis for the construction of type-scenes. Furthermore, I connect cognitive theory with M. Nagler’s Gestalt, A. N. Sabynin’s DRK-structures and J.M. Foley’s traditional referentiality, which are based on a metonymy. On that basis, I present some examples of traditional images of “house” in the Odyssey, which consist of recurrent elements, such as “megaron,” “bedroom,” “wife,” “children,” etc. The singer evokes the traditional image of the “house” using metonymy. The analysis of examples reveals that these images, regardless of the exact words used by the singer, are stable—just as the type-scenes built on M. Clark’s basic scaffolding.

Plato’s Protagoras belongs to the most read and analyzed works of the philosopher. Interest is aroused not only by the content of the work, but also by its form: diligent composition, elaborate descriptions of characters and dramatic nature of separate scenes, although the work belongs to the group of narrative dialogues. The aim of this article is to analyze the prologue of Protagoras, which consists of five scenes (309a–316a), to answer the question what function they have and how important role they play in this dialogue.

Opis:
Despite numerous publications on the soundscape of Wroclaw and the history of major music festivals like Jazz nad Odrą, not enough attention has been devoted to the local, independent activity of popular music artists. This article is a contribution to contemporary research into the popular music scene in Wroclaw. The author has carried out his own research in the summer and autumn of 2019, focusing on rock music and jazz. This is because, according to surveys, these types of music are most often indicated as specific to Wroclaw. The author’s goal is to indicate the reasons for the popularity of specific popular types of music and to determine the features specific to the popular music scene in Wroclaw. Into account is taken the history of the city and the repertoire of contemporary concerts as well as the reception of the events and the soundscape of places and the entire city. The author presents the methodology (sound walks, participant observation, surveys, interviews) using literature on the subject of popular music studies, soundscape studies and performance studies.
