Transparency, cognition and interactivity : toward a new aesthetic for media art

Zics, Brigitta January 2008 (has links)
This practice-based thesis undertakes research into the contemporary aesthetic of interactive media art, in order to propose a useful practical model of interactivity founded on a critical approach to both existing theory and practice. It proceeds from the identification of a primary lack in contemporary aesthetics that arises from the predominantly materialistic comprehension of technologically-mediated artworks. The thesis establishes a new model for interactive art that offers an immaterial engagement with technology at a locus where cognition and the aesthetic intertwine. This model is constructed following a revision of both the theory and practice of interactive media art, which identifies a materialistic bias of technology-mediated art production caused by a confused concept of technology as both tool and medium. This investigation confines itself to the last forty years of interactive art and the new model of spectatorship that has accompanied it. The main objective of what follows from this investigation is an account of agency in the artist and spectator interrelationship. In the context of technologically based artworks various approaches to spectatorship have frequently remained within the constraints of the traditional model of art that inherently drew on a separation between body and mind. It is argued in this thesis that neither the technology nor the participation itself, but the cognitive interconnection between 'artist-artwork-spectator' produces the primary aesthetic dimension of interactive media art. In this respect, not the physical object creation but the aestheticisation of this triangle produces the here identified immaterial/cognitive experience of the spectators. This can be achieved when the technology is applied as a transparent medium one of the core concepts introduced in this thesis which can facilitate an aesthetic quality or meaning creation through technology. The 'transparent medium' enables the cognitive-based experience production, which is identified as the immersive flow of the spectator's aesthetic experience. As such, the re-evaluation of the artist- spectator interrelationship proposes a new immaterial model of art which is called the Transparent Act. The introduction of the Transparent Act leads to the main intervention of this thesis which lies in an effort to recover a lost dimension in interactive media art. A recovery of this dimension enables access to a knowledge practice which is not necessarily located in ordinary cognitive experiences but in unfamiliar conscious states that can be compared to accounts of so-called spiritual experiences. The model of the Transparent Act is concurrently applied as a practise-based intervention and proof-of-concept in a major installation, the Mind Cupola. This artistic and technological contextualisation of the original intervention of this thesis is exemplified as an affective environment which aims for an immediate cognitive affection of the spectator by generating mechanical and audio-visual effects in the spectator's 'mind'. The artistic system uses special face analysis techniques to close the feedback loop and affect the spectator through the analysis of her/his reactions. The installation is built upon a 'passive' modality of interaction in which the spectator contributes to the artwork with subtle, cognitive-based interactions which are fed back through a complex open response system. The implementation of cognitive feedback loops, also described as the fractal structure in the spectator's cognition, constitutes the essential transparent medium through which the previously lost immaterial dimension of a spiritual-like aesthetic experience in interactive media art is achieved. The thesis concludes with suggestions of further applications including the evaluation of technologically mediated artworks.

Avaliação do efeito de ataque por escória em massas de socar refratárias Al2O3 - C - SiC, para fornos cubilôs / Attack effect evaluation in ramming refractory Al2O3-C-SiC, for cupola furnace

No. of bitstreams: 1 Roni Cardoso da Silva.pdf: 10468116 bytes, checksum: 057798ee5264b472b4aa18c7bfeca993 (MD5) Previous issue date: 2015-02-12 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The use of refractory ramming mass consisting of Al2O3-C-SiC cupolas furnace is constant casting processes. In the process, the contact face between the refractory lining and the liquid bath allows interaction between slag and refractory at high temperatures. Corrosion or impregnation of molten metal and slag in refractory depends on factors such as porosity, wetting angle and the reactivity of the slag in relation to refractory solid contact. This study evaluated the effect of slag attack in different refractory applied by ramming made of Al2O3-C-SiC depending on the amount of compression. In addition, a study was conducted `` post-mortem`` of a refractory sample after use in operation. The results allowed correlating the compression efficiency with the effect of corrosion of slag by the static method, and to evaluate the mechanical behavior cold and hot these materials and the influence of chemical composition and particle size of the material. Refractory more easily compression showed the best results for the static slag attack, which highlights the importance of compression efficiency in the field performance of this type of refractory. The analysis of the sample after use in the field demonstrated oxidation and slag penetration-promoting agents as the principal for corrosion in the slag line region. / A utilização de massas refratárias de socagem constituídas de Al2O3-C-SiC em fornos cubilôs é constante em processos de fundição. No processo a face de contato entre o revestimento refratário e o banho líquido possibilita a interação entre escória e refratário em altas temperaturas. A corrosão, ou impregnação do metal fundido e escória, no refratário depende de fatores como a porosidade, ângulo de molhamento e a reatividade da escória em relação ao sólido refratário em contato. Neste trabalho foi avaliado o efeito de ataque de escória em diferentes refratários aplicados por socagem constituídos de Al2O3-C-SiC em função da intensidade de compactação. Também foi realizado um estudo ``post-mortem`` de uma amostra de refratário após o uso em operação. Os resultados permitiram correlacionar a eficiência de compactação com o efeito de corrosão da escória pelo método estático, bem como avaliar o comportamento mecânico a frio e a quente destes materiais e a influência da composição química e granulometria do material. Os refratários com maior facilidade de compactação apresentaram os melhores resultados quanto ao ataque de escória estático, o que evidencia a importância da eficiência de compactação no desempenho em campo deste tipo de refratário. A análise da amostra após utilização em campo evidenciou a oxidação seguida de penetração de escória como principais agentes promotores da corrosão na região da linha de escória.

Víceúčelový objekt v Plzni / The multipurpose building in Plzeň

Perhalová, Anna January 2018 (has links)
The subject of this diploma thesis is design and static assessment of timber load bearing structure of multipurpose building in Plzeň. It is cupola consited of two radial curved ribs above a triangle ground plan with one oval edge. I got this shape by cutting the cupola vertically on these two triangle edges and that created two walls of the construction. The largest ground plan dimension of load bearing structure is 54,4 meters and the maximum height is +18,0 meters. The design is processed in two various drafts.

Římské lázně a saunový svět. / Roman spa - sauna world

Trávníček, Jiří January 2013 (has links)
The subject of this thesis is an architectural study of Roman spa and sauna world that connects seamlessly to a specialized atelier with theme Aquacentre - "Water Temple" Brno. The project is located to the upper floors front cupola waterpark, which is composed of monolithic reinforced concrete skeleton and its building envelope brings arched laminated wood trusses. The main task was to create the interior space. The source of inspiration was the whirlpool, which is transcribed into the design of furniture.

Sedláková, Jitka January 2010 (has links)
The subject of this work is to validate the possibility of managing the cast iron strength through residual Mg content and to determine methodically whether it is possible to exploit this technology in a foundry. It is another subject to determine the economics of the exchange of cupola furnace for electric induction furnace and methodically assess the possibilities of melting in the electric induction furnace.
