Listeners' emotional engagement with performances of a Scriabin étude : an explorative case study
No full textContains fulltext :
56757.pdf (Publisher’s version ) (Closed access)In an explorative study, the variation in listeners' judgments of the emotionality of three performances of a Scriabinétude was investigated. Three performances of the Scriabinétude were recorded. Video and/or audio recordings were presented to 24 listeners who segmented the music in short phrases and indicated their emotional engagement with the music using a slider. The relation between the performance data and the listeners' responses was analysed as well as the effects of musical training, medium and musical structure. The analyses were done using multiple regression analyses and decision trees. The results confirmed the hypothesized influence of the performer's interpretation, the listener's background and the global phrase structure, though not always in the expected way. In particular the dynamics of the performance correlated with listeners' judgments of emotionality, while tempo correlated more strongly with the indications of phrase structure. This was more clearly the case for nonmusicians than for musicians. The movements of the pianist were related to the dynamics of the performance and seemed to aid the communication of emotional intensity.30 p
Interactive system for music visualisation on the web
No full textDiplomska naloga se osredotoči na razvoj interaktivnega spletnega sistema, ki uporabniku omogoča in karseda olajša interaktivno upodabljanje glasbe na platno HTML (HTML canvas). Gre za sistem, preko katerega uporabnik manipulira s prikazano sliko na platnu, ter tako s pomočjo zvoka, ki se predvaja v ozadju, upodablja glasbo. Sam uporabniški vmesnik tega sistema mora biti enostaven, razumljiv ter predvsem prijazen do uporabnika, saj mora pri upodabljanju glasbe uporabnik hitro reagirati in nima časa za iskanje želenih funkcij vmesnika.
Sistem je predstavljen v obliki spletne strani. Za implementacijo se torej koristijo glavne spletne tehnologije, kot na primer HTML, JavaScript ter CSS. V tem okolju sta na voljo dva glavna načina interaktivne vizualizacije glasbe: v živo ali live, kar pomeni, da pri upodabljanju glasbe sodeluje več uporabnikov in solo ali samostojen način, kjer uporabnik sam upodablja glasbo in mu je tako na voljo več funkcij. Na voljo je tudi ogled ali prenos posnetka seje, v kateri se je upodabljala glasba na platno.This thesis focuses on the development and implementation of interactive web system, that is meant for sound vizualization. User can use this system to manipulate sound and displayed image, thus visualizing the sound on an HTML canvas. The user interface must be simple, understandable and above all user friendly, because while visualizing, user must react quickly and does not have the time to search for the desired functionality of the interface.
The system is presented in the form of a website, therefore, web technologies such as HTML, JavaScript and CSS are used for implementation. There are two main ways in which the user can visualize sound: live mode, in which there are number of users involved in the visualization and solo mode, where the user visualizes the sound by himself, therefore havinig access to other functions, which are not available in live mode. All vizualization sessions are of course recorded and can be later watched or downloaded
Komu (pravo) zvoni? O pravnem in družbenopolitičnem izključevanju nedokumentiranih migrantov [For Whom the Law Tolls? On Legal and Sociopolitical Exclusion of Undocumented Immigrants]
No full textThe author examines the reasons for the undocumented immigrants’ vulnerability in their host countries. He claims that the main reason for this is the illegality of their residence on the territory of a particular country. The latter assumes the role of an all-determining legal status which, among other, exposes the undocumented immigrants to a high degree of arbitrariness in their contacts with host country frontline legal officials. Moreover, the social environmentn into which they come is often saturated with false claims about their intentions, deliberate perpetuation of negative stereotypes and widespread fearmongering against foreigners. Thus, the author argues that arbitrariness as a mechanism of legal exclusion of undocumented immigrants is often complemented and reinforced by mechanisms of their socio-political exclusion. The paper examines the characteristics of these exclusionary mechanisms and demonstrates how they complement one another. In pursuit of this goal, the author combines a legal-philosophical analysis of the relevant legal phenomena with a sociological and political science analysis of the language practices which form in reference to undocumented immigrants. Finally, in the second part of the article, he tests the theses and the methodological approach from the first part on the case of the Erased in Slovenia. He concludes by arguing that the exclusion of undocumented immigrants is a complex legal and sociopolitical phenomenon
Legality on the Frontlines of Administrative Decision-Making
No full textIn this essay, the author deals with the decision-making practices of frontline administrative officials. In particular, he examines how administrative circulars become the primary source of these officials’ decision-making norms, even when their content may be in contrast with hierarchically superior sources of law. The disposition of frontline officials to resort primarily to internal orders of hierarchically superior officials is explained as a consequence of the joint influence of several organizational principles upon their mental faculties. After introducing the problem and its relevance for legal theory, the author first defends the methodological approach to which he subscribes. Thereafter, he presents the central categories and organizational principles framing the institutional operations of public administrations. Finally, he provides a psychologically-informed explanation of the influence exerted by these principles upon the mental faculties of frontline officials which underpin the latter’s preference for the use of administrative circulars as primary sources of decision-making norms
MATIJA ANTUN RELKOVIC’S GRAMMAR
No full textThis work presents some relatively extensive account and review of one of the oldest grammars in Croatian or Serbian language. The speech is about A New Slavonic and German Grammar by Matija Antun Relkovic printed in Zagreb for the first time in 1767. Special attention has been drawn to those parts of the description which are specific for Relkovic for some reason or other. Some characteristics have been considered (e. g. graphic solutions, the description of ani- mate/inanimate category, the description of noun morphology and the use of nouns, the advantage of contrastive description and the like) and deficiencies of the applied description (influence of German and Latin languages, terminological awkwardness and poverty, inadequate conception of the dictionary, insufficient linguistic knowledge of the author and the like). This grammar has been compared with other older grammar books, especially with the first Croatian grammar by Bartol KaSic
Evaluation of algorithms for speaker diarization in sound recordings
No full textSegmentacija govorcev (diarizacija) je postopek, ki razdeli zvočni posnetek na odseke glede na identiteto govorcev. Segmentacija govorcev v zvočnih posnetkih nam da odgovor na vprašanje kdo je kdaj govoril.
V tem diplomskem delu se posvetimo avtomatični segmentaciji govorcev v različnih zvočnih posnetkih. Pripravimo si testno množico zvočnih posnetkov v slovenščini, ki jih pridobimo iz terenskih posnetkov. Posnetki vsebujejo dva ali več govorcev in zelo pogosto tudi druge zvoke, tišino, prekrivanje med govorcema in podobno. Zanje ročno zgradimo transkripcije za število govorcev in časovni interval govora posameznega govorca, ki bo predstavljal našo resnico (angl. ground-truth). Nad testno množico poženemo vse algoritme za diarizacijo, ki jih ocenjujemo. Napišemo program, ki za vhod vzame rezultate vseh algoritmov, ki imajo različne formate in vrste zastopanja rezultatov, ter jih pretvorimo v enotno obliko. Ocenjujemo natančnost algoritmov in analiziramo, kako dobro delajo v različnih situacijah.Speaker segmentation (diarisation, diarization) is a process that separates the audio clip in sections regarding the identity of the speakers. Speaker diarization in sound recordings answers the question of who spoke when?
This thesis is dedicated to the automatic segmentation of speakers in a variety of sound recordings. We prepare a test data of audio recordings in Slovenian, which are obtained from field recordings. The recordings contain two or more speakers and very often they contain other sounds, silence, overlap between the speakers and the like. We manually build transcriptions for the number of speakers in them and the time interval of the speeches for each speaker which will represent our ground-truth. We run all the algorithms for diarization that we evaluate on this test data. We write a program which takes the results from the algorithms as an input which have different formats and different types of representation, and the results are converted to a common format. We evaluate the accuracy of the algorithms and analyse how well they work in different situations
Interactive visualization of spatial data in Unity3D
No full textIn our thesis, we developed a prototype of an interactive 3D terrain visualization of Slovenia. We merged LiDAR data in form of height maps with orthophoto images, which were downloaded from the Slovenian Environment Agency's servers. We developed the prototype in Unity3D with programming language C\#.
For successful interactive visualization, we implemented multiple support systems. We divided the terrain into tiles. Each tile consists of metadata and terrain. The terrain was generated from height maps and ortophoto images. For correct alignment, we implemented an offset alignment system and control point system.
Because of a high number of tiles, we implemented a level of detail system. The closer the camera is to the terrain, the higher resolution tiles are loaded and shown. The system also helped us with better memory management, as there are fewer tiles loaded in the memory. Tiles are linked together into a hierarchy, which is managed by a data structure called TreeStructure, which is grouping tiles into 33 grid.
Images were loaded and processed asynchronously, via coroutines, which helped us maintain a responsive user interface.
For additional performance gains, all images were converted to a proprietary format, which enabled us to use faster Unity functions
Visualisation and segmentation of volumetric data in the RenderCore framework
No full textPodročje analize medicinskih slik in vizualizacije ter segmentacije medicinskih podatkov je zelo aktualno. V ta namen obstaja veliko orodji, ki uporabnikom pomagajo pri različnih nalogah. Cena, platformna odvisnost in nezmožnost deljenja ter shranjevanja podatkov so le nekateri izmed problemov obstoječih rešitev. V magistrskem delu se zato osredotočimo na razvoj novega orodja, ki poskuša rešiti te probleme. Najprej razširimo ogrodje RenderCore, ki omogoča lažji in hitrejši razvoj aplikacij za upodabljanje 3D računalniške grafike v spletnem brskalniku. Dodamo mu funkcionalnosti za delo z volumetričnimi podatki v obliki 3D tekstur. Na podlagi razširitve nato izdelamo spletno aplikacijo Volume Viewer, ki uporabnikom omogoča vizualizacijo in ročno segmentacijo volumetričnih podatkov. V magistrskem delu opišemo implementacijo razširitve, kot tudi dele in funkcionalnosti razvite aplikacije. Delovanje naše aplikacije analiziramo v kontroliranem okolju z umetno generiranimi podatki, prav tako pa tudi na realnih primerih iz prakse. Na koncu podamo možnosti nadgradnje naše aplikacije ter možnosti uporabe aplikacije pri različnih projektih v prihodnosti.Medical image analysis with visualization and segmentation of medical data is a very active field. Because of this, many tools for helping users with various tasks have already been developed. Price, platform dependency and inability to share and store data are just some of the problems that current solutions have. Therefore, in the master\u27s thesis, we focus on the development of a new tool that tries to solve these problems. We first extend the RenderCore framework, which allows easier and faster development of applications for rendering 3D computer graphics within web browser. We add functionalities for working with volumetric data in the form of 3D textures. Based on the extension, we then develop web application Volume Viewer, which allows users to visualize and manually segment volumetric data. In the master\u27s thesis, we describe the implementation of extension as well as parts and functionalities of developed application. We analyze the functionality of our application in a controlled environment with artificially generated data, as well as with real cases from practice. In the end, we present the possibilities for upgrading our application and the possibilities of using our application in various future projects
