Theatrical virtual acoustic rendering with head movement interaction
2019
AbstractNowadays, the use of virtual reality/virtual acoustics (VR/VA) in archaeology for rendering lost buildings is an important topic in the cultural heritage field. Moreover, the addition of additional senses apart from the sight increases the feeling of immersion in virtual environments. The aim of this paper is to show the interaction work developed in a VA system, based on Unity and FMOD, the graphical and acoustical reconstruction of an ancient building and the development of a VR goggles with headphones to render 3D audio and video interactively. This system has been implemented to render auralizations in a binaural system and has been applied to the renderization of an old and los…
Photosensitive polyurethanes for optical record
2011
The method of synthesis of photosensitive polyurethanes polymers on glycerine, toluenediisocyanate and Disperse Red 1 base has been described. Two types of polymers with different amount of Disperse Red 1 fragments in macromolecules were compared. Films of the polymers were obtained from solutions in organic solvents on glass substrate. The dry film thickness was in the range of 3,5 - 4.5 μm. The transmission spectrums of the films were studied. Possibility of formation of side product in the process of synthesis was observed. The photobirefringence measurements of polymers films were performed. Surface relief grating (SRG) formation was observed during polarization holographic recording pr…
Optical Field-Induced Mass Transport in Soft Materials
2013
Abstract The dependence of the surface relief formation in amorphous chalcogenide (As 2 S 3 and As-S-Se) and Disperse Red 1 dye grafted polyurethane polymer films on the polarization state of holographic recording light beams was studied. It is shown that the direction of lateral mass transport on the film surface is determined by the direction of light electric vector and photoinduced anisotropy in the film. We propose a photoinduced dielectropfhoretic model to explain the photoinduced mass transport in amorphous films. Model is based on the photoinduced softening of the matrix, formation of defects with enhanced or decreased polarizability, and their drift under the electrical field gradi…
Is It Possible to Educate, Intervene or “Cure” Autism Spectrum Disorder? A Content Analysis of YouTube Videos
2021
YouTube es uno de los sitios web más conocidos y de mayor acceso en todo el mundo, por lo que tiene un gran potencial pedagógico. No obstante, la calidad y la veracidad de algunos videos de YouTube son cuestionables. Las dudas sobre la confiabilidad del contenido fáctico es un factor controvertido que debe tenerse en cuenta, especialmente cuando se abordan cuestiones de salud pública. Por ello, el principal objetivo de este trabajo es analizar el contenido de los vídeos en español más vistos en YouTube relacionados con el trastorno del espectro autista (TEA). Para la realización de esta investigación se utilizaron los términos "autismo Y educación", "autismo Y intervención" y "autismo Y cur…
Removing ocular artifacts from magnetoencephalographic data on naturalistic reading of continuous texts
2022
Naturalistic reading paradigms and stimuli consisting of long continuous texts are essential for characterizing the cortical basis of reading. Due to the highly dynamic nature of the reading process, electrophysiological brain imaging methods with high spatial and temporal resolution, such as magnetoencephalography (MEG), are ideal for tracking them. However, as electrophysiological recordings are sensitive to electromagnetic artifacts, data recorded during naturalistic reading is confounded by ocular artifacts. In this study, we evaluate two different pipelines for removing ocular artifacts from MEG data collected during continuous, naturalistic reading, with the focus on saccades and blin…
Applying sound art research in modern electronic music production : glitch, loop, plunderphonics and sound collage as tools of production
2011
Tämä työ tehdään empiirisenä tutkimuksena äänitaiteesta ja sen suhteesta moderniin elektroniseen musiikkiin. Tätä tutkimusta varten suoritetut äänikokeilut seuraavat muutamia äänitaiteen historian pääsuuntauksia ja kertovat, miten nämä suuntaukset ovat vaikuttaneet elektronisen musiikin tuottajiin. Tutkimus on jaettu neljään osaan, joissa tutkitaan taiteen ja populäärimusiikin välistä suhdetta. Lisäksi kerrotaan, kuinka kokeellista musiikkitaidetta voidaan käyttää modernin elektronisen musiikin tuotantotyökaluna. Ensimmäinen kappale käsittää Glitch- ja Loopmusiikin väliset roolit välittömän ja välillisen nautinnon tuottajana Loop-pohjaisessa musiikissa. Samalla toinen ja kolmas kappale tutk…
Enregistrer les interactions au restaurant : atouts et contraintes d’un cadre expérimental
2013
Dans le cadre d’un travail de recherche en Analyse Conversationnelle (Sacks, 1992) traitant des dimensions linguistiques et multimodales des interactions entre le personnel de service et les clients lors d’un repas au restaurant, nous avons élaboré une partie de notre corpus dans un restaurant expérimental équipé d’un système d’enregistrement audio et vidéo. Dans cet article, nous exposerons comment ce dispositif a été utilisé pour la constitution de notre corpus afin de capter des données authentiques enregistrées dans leur contexte naturel de production.Grâce à l’analyse fine de deux extraits, nous montrerons que le dispositif technique à disposition dans cette structure ne peut pas être …
Aligned microcontact printing of biomolecules on microelectronic device surfaces
2001
Microcontact printing (/spl mu/CP) of extracellular matrix proteins is a fascinating approach to control cell positioning and outgrowth, which is essential in the development of applications ranging from cellular biosensors to tissue engineering. Microelectronic devices can be used to detect the activity from a large number of recording sites over the long term. However, signals from cells can only be recorded at small sensitive spots. Here, the authors present an innovative setup to perform aligned /spl mu/CP of extracellular matrix proteins on microelectronic devices in order to guide the growth of electrogenic cells specifically to these sensitive spots. The authors' system is based on t…
Space-Frequency Quantization for Image Compression With Directionlets
2007
The standard separable 2-D wavelet transform (WT) has recently achieved a great success in image processing because it provides a sparse representation of smooth images. However, it fails to efficiently capture 1-D discontinuities, like edges or contours. These features, being elongated and characterized by geometrical regularity along different directions, intersect and generate many large magnitude wavelet coefficients. Since contours are very important elements in the visual perception of images, to provide a good visual quality of compressed images, it is fundamental to preserve good reconstruction of these directional features. In our previous work, we proposed a construction of critic…
Book and Radio Play Silences : Medial Pauses and Reticence in ‘Murke's Collected Silences’ by Heinrich Böll
2019
This article analyses silence at the interface between print and audio media by reading and listening to Heinrich Böll's short story ‘Murke's Collected Silences’ (‘Doktor Murkes gesammeltes Schweigen’) in its book (1958) and three German-language radio play versions (1965; 1986; 1989). Reference is also made to Benjamin Gwilliam's sound art piece (2007) based on the 1986 adaptation. The Böll story thematises silence and media in various ways, and has definite countertextual aspects, in the sense of technology, textuality, and materiality of language. In the printed story, silence is either verbally named or typographically indicated, whereas the radio plays present or perform it. The compar…
