Fanchoreografien als koordinierte Formen kommunikativen Kollektivhandelns: Beobachtungen aus semiotischer Perspektive
Get PDFBei Fanchoreografien handelt es sich um koordinierte multimodale Formen kommunikativen Kollektivhandelns. Choreografierte Fankommunikation in Sportstadien verdankt ihre Existenz dem Umstand, dass ein vor Ort anwesendes Großpublikum an der koordinierten Durchführung einer kommunikativen Handlung beteiligt ist. Für semiotische und medialitätstheoretische Fragestellungen bietet dieser eigens zu kategorisierende Kommunikationstypus eine Fülle von konzeptionellen und theoretischen Herausforderungen, die bislang noch kaum Beachtung gefunden haben. Dazu gehören unter anderem Fragen zur Autorschaft oder auch zur Bedeutung des physischen und des sozialen Raums.In this contribution fan choreographies are understood as coordinated mul¬timodal forms of communicative collective action. Fan choreographies in sports stadi¬ums owe their existence to the fact that a large on-site-audience is involved in the coor¬dinated execution of a communicative action. From a semiotic and media-theoretical perspective, this type of communication has to be categorized specifically. And it offers a wealth of conceptual and theoretical challenges that have so far received little atten¬tion in audience research. These include questions of authorship as well as the meaning of physical and social space
Selbstbehauptung: Rollenfiktion zwischen Starimage und Authentizitätsanspruch als Harmonisierung kultureller Oppositionen in Hildegard Knefs "Für mich soll’s rote Rosen regnen"
Get PDFDer Beitrag untersucht mit Hilfe der Kategorien ‚Sprache‘, ‚Musik‘ und ‚Starimage‘ die mentalitätsgeschichtlichen Funktionen des Schlagers Für mich soll’s rote Rosen regnen von Hildegard Knef. Dabei werden die zentralen Semantiken, insbesondere die Konzeption der Person, herausgearbeitet, die im Zusammenspiel von Text und Kontext die Bedeutungen des Schlagers konstituieren. Erläutert wird abschließend, wie diese Semantiken in der Adaptionsgeschichte des Schlagers an neue Gegenwarten angepasst werden, um den kulturellen Referenzraum des Schlagers auszuloten.The article examines the historical mental functions of the hit song (\u27Schlager\u27) Für mich soll’s rote Rosen regnen by Hildegarde Neff (aka Hildegard Knef) using the categories \u27language\u27, \u27music\u27and \u27starimage\u27. The central semantics, in particular the concept of person, which in the interplay of text and context makes up the meaning of the \u27Schlager\u27, is worked out. Finally, it will be explained how these semantics are adapted to the present in the adaptation history of the song, in order to sound out the cultural reference space of the \u27Schlager\u27
Von der Schichtung zur Palimpsestierung: „Palimpsest“ als kulturwissenschaftlicher Grundbegriff
Get PDFDer Ausdruck ‚Palimpsest‘ schickt sich an, ein kulturwissenschaftlicher Grundbegriff zu werden. Als analytische Kategorie erfasst ‚Palimpsest‘ horizontale und vertikale Lagerungen von Raum und Zeit und betont dabei Aspekte der Mischung, der Neugestaltung, der Disruption, der Zerstörung und des Verlusts. Deshalb ergänzt und präzisiert er zunehmend die Schichtenmetaphern, wie jüngere Methodendiskurse in der Archäologie und der Literaturwissenschaft belegen, und erschließt auf neuartige Weise Querschnittsthemen der Kulturwissenschaften – etwa aus dem Bereich der Raum-und Stadttheorie oder im Hinblick auf das Spannungsfeld von Gedächtnis/Erinnerung, Diskurs und Identität. Zur weiteren Operationalisierung des Palimpsestbegriffs ist es erforderlich, zum einen epistemisch zwischen einem materiellen und einem metaphorischen Begriffsverständnis zu unterscheiden. Zum anderen gilt es, den Begriff der Palimpsestierung als vermittelnde Prozesskategorie zu profilieren.The concept of the palimpsest has increasingly been promoted as a key concept in cultural studies. It captures the horizontal and vertical layers of space and time, and emphasises aspects of mixture, restructuring, disruption, destruction, and loss. Therefore, it replaces metaphors of layering, as recent methodological discourses in archaeology and literary studies attest to. At the same time, it opens new perspectives on cross-sectional topics not only in cultural studies but also in the context of spatial and urban theory as well as with regard to the tension between memory/remembering, discourse, and identity. To further operationalise the concept of the palimpsest within a wider academic framework, it is necessary, on the one hand, to distinguish between a material and a metaphorical notion of the term. On the other hand, it is essential to establish a concept of palimpsestisation as a mediating process category
Model Order Reduction with Dynamically Transformed Modes for Electrophysiological Simulations
Get PDFThe numerical simulation of neuromuscular processes in skeletal muscles typically imposes high computational costs, resulting in the need for techniques to reduce these costs. One submodel in these types of multiphysics multiscale simulations is the electrophysiological model, describing the propagation of an action potential (AP) in a muscle fiber. Involved in the simulation of the propagation are two traveling waves, resulting in difficulties for classical model order reduction (MOR) techniques based on linear subspaces.
Instead, we apply the nonlinear MOR method shifted Proper Orthogonal Decomposition (sPOD) to construct dynamically transformed reduced basis functions depending on time-dependent paths spanning the adaptive reduced ansatz space.
Our numerical experiments demonstrate that the constructed reduced ansatz space can accurately capture the dynamics of two fully separated wavefronts and reduce the degrees of freedom of the whole simulation. However, it cannot represent the activation of the AP in the center of the fiber and overlapping wave parts. The constructed reduced order model outperforms the high-dimensional full order model in terms of the computational costs while the accuracy is maintained and reaches speedup factors between 2 and 73 depending on the time discretization

Moreover, there is need to operate the content of training for teacher development. The paper concludes with recommendations for further investigation
Automated Identification of Wood Surface Defects Based on Deep Learning
Get PDFWood plates are widely used in the interior design of houses primarily for their aesthetic value. However, considering its esthetical values, surface defect detection is necessary. The development of computer vision and CNN-based object detection methods has opened the way for wood surface defect detection process automation. This paper investigates deep-learning applications for automatic wood surface defect detection. It includes the evaluation of deep learning algorithms, including data generation and labeling, preprocessing, model training, and evaluation. Many adjustments regarding the dataset size, the model, and the modification of the neural network were made to evaluate the model\u27s performance in the specified challenge. The results indicate that modifications can increase the YOLOv5s performance in detection. The model with GCNet added and trained in 4800 images has achieved 88.1% of mAP. The paper also evaluates the time performance of models based on different GPU units. The results show that in A100 40GB GPU, the maximum time to process a wood plate is 2.2 seconds. Finally, an Active learning approach for the continual increase in performance while detecting with the smaller size of manual labeling has been implemented. After detecting 500 images in 5 cycles, the model achieved 98.8% of mAP. This scientific paper concludes that YOLOv5s modified model is suitable for wood surface defect detection. It can perform with high accuracy in real time. Moreover, applying the active learning approach can facilitate the labeling process by increasing the performance during detection
Tahrir Is Not a Square. Wie meta-urbane Protestkommunikate städtische Territorien des Widerspruchs strukturieren.
Get PDFZusammenfassung. Schrift im öffentlich zugänglichen Raum der Stadt ist ein wichtiger soziolinguistischer Forschungsgegenstand. Aufschriften aller Art prägen nicht nur den urbanen Raum, sondern bringen spezifische Orte erst hervor. Im Zentrum der Analyse steht die Konstruktion eines urbanen Protestraums, wie er durch sogenannte Protestkommunikate hervorgebracht wird. Beispiel ist dabei ein Stencil, das auf den Tahrir-Platz in Kairo zu verweisen scheint, das jedoch über interspatiale, interdiskursive und intermediale Bezüge weit mehr leistet. Es ist Teil einer Ortsassoziation, die den urbanen Raum als Territorium des Widerspruchs beschreibbar macht. Der Beitrag leistet einerseits eine ethnographische Detailanalyse zu einem Schriftvorkommen in Berlin Prenzlauer Berg, er gibt darüber hinaus aber vor allem auch Hinweise auf Möglichkeiten einer soziolinguistischen und semiotischen Analyse urbaner Widerspruchsterritorien überhaupt.Summary. Inscriptions in the publicly accessible space of the city are an important research topic of sociolinguistics. Writings of all kind do not only shape urban space but also produce specific places which wouldn’t exist without them. The focus of this paper is how a space of urban protest is constructed; it will be shown how communicative forms of protest create place. The example discussed is a stencil which specifically refers to the Tahrir square in Cairo but at the same time accomplishes much more through interspatial, interdiscursive, and intermedial references. This stencil can be understood as part of an association of places which makes urban space describable as a territory of contradiction. The contribution provides a detailed ethnographic analysis of the use of stencils in Berlin Prenzlauer Berg and goes on to highlight possibilities of a sociolinguistic and semiotic analysis of urban territories of contradiction at large
Phonetische Transkription als folklinguistische Zeichen-Praxis im öffentlichen Raum
Get PDFZusammenfassung. Diese Studie ist eine erste Erkundung von laienlinguistischer Nutzung phonetischer Transkription im öffentlichen Raum. Dabei handelt es sich um Gebrauchsformen, bei denen das semiotische Repertoire der Transkription – beispielsweise phonetische Symbole und die Klammerung von Lexemen, aber auch Silbentrennung und lexikografische Textstruktur – in der digitalen oder materiellen Öffentlichkeit in einen dekontextualisierten Zusammenhang gebracht wird. Damit verbindet sich ein intendierter Effekt, der von der etablierten visuellen Repräsentation sprachlicher Laute abweicht. Um diesen Zusammenhang genauer zu erkunden, wurde ein Bildkorpus mit 27 Beispielen aus dem öffentlichen Raum erstellt und im Hinblick auf semiotische und soziolinguistische Variation analysiert. Es konnte eine große Bandbreite an semiotischen Realisierungen nachgewiesen werden, die von komplexen Formen mit hoher Transkriptionstiefe bis hin zu minimalistischen Varianten reicht. Ausgehend von dieser Analyse werden verschiedene soziostilistische Faktoren herausgearbeitet, die für die Variation eine Rolle spielen (Professionalisierungsgrad, Planungsaufwand, Korrektheit), und es werden vier Dimensionen sozialer Bedeutung unterschieden (Selbstreflexivität, definitorische Sprechakte, inszenierte Mündlichkeit, Erzeugung von Fallhöhe), die mit folklinguistischen Transkriptionen aktiviert werden können.Summary. This paper is a first exploration of folk-linguistic forms of phonetic transcription in the public space. This concerns patterns of use where the semiotic repertoire of phonetic transcription – including the use of phonetic symbols and bracketing, but also syllabic word division and lexicographic text structure – is transposed into a non-technical context of digital or physical public space, and where the intended purpose differs from linguistic traditions of visually representing speech sounds. To elucidate this practice, a corpus of 27 pictures was assembled in an ethnographic approach and analyzed from a semiotic and sociolinguistic perspective. A broad spectrum of semiotic phenomena was found, ranging from highly complex and quasi-professional transcriptions to minimalistic approaches. On this basis, a range of socio-stylistic factors that influence this variation (degree of professionalization, amount of planning, correctness) is proposed. Four categories of social meaning are distinguished (metalinguistic reflexivity, agenda setting, staged orality, deviance) that can be used for self-positioning in the use of folk-linguistic transcriptions in public spaces
