TRIZ-Based S-Curve Analysis of Evolutionary Trend of LED Lights
by Xin Zhang
Abstract: With the evolution of technology systems, main parameters of value (MPV) show an s-curve development with time. This paper presents a general TRIZ-based s-curve analysis of the technology evolution of LED lights as well as the similarities and differences in the evolution of incandescent lamps, gas discharge lamps and LEDs. S-curve analysis is strategically meaningful in making technical development plans, and evolution laws will facilitate in predicting the future of LEDs. Understanding them will offer possibilities for tool-assisted problem solving.
Keywords: S-curve,LED lights,evolutionary trends.
Voyage around my screen, voyage around with my screen: Space perception from physical, through digital, to hybrid
by Georgios Papakonstantinou
Abstract: Navigating and communicating within urban space is a fundamental everyday life activity. Human spatial conception and experience could be categorized in three different states: a) presence in the physical environment, b) presence in a virtual environment, mediated by representation technologies, either analog or digital, c) mental presence in an imaginary environment. This text focuses on the emergence of a fourth state of spatial experience, that of the synthetic spatial context, afforded by mobile computing and location detection technologies. Contemporary urban environments offer a multiplicity of layers of information (social, historical, etc.) through material elements and display systems communication. Mediated spatial activity in digital environment is mapped onto the physical, urban environment. Thus, mediated digital content and physical spatial experience are projected onto the urban space.
Keywords: visual representation; urban representation; physical space; digital space; hybrid space; urban space; locative media; media archeology; screen space.
A hybrid way to navigate the city: Visual and aural cartography of the city of Athens
by Katerina Antonaki, Eleni GLINOU
Abstract: Our experience of the city is formed through a constant symbiosis with a vast amount of printed information. In this article we illustrate the aural aspects of those printed information in the urban space. We do that by referring to current discourses around visual and sound theories and by engaging contemporary open source technologies / software.The text is part of a wider design-research project which is in progress and which investigates the aural qualities of the printed information of urban space and tries to translate the so called visual noise of urban space into sound. The article is based in the conceptual end of designing an app which will translate the visual noise of urban space into sounds.
Keywords: Hybrid narrations; image and sound; urban soundscapes; urban informatics; visual noise; aural cartography; silent readers; visual identity; aural identity of the city; aural dimension of images; city soundtrack; visual and aural stimuli.
Preservation of an interactive computer-based art installation---a case study
by Borut Batagelj, Franc Solina
Abstract: In contemporary digital art computer technology plays an integral part not only in the creation of art pieces but also in their functioning as art works. Such digital art works have usually a performative or interactive character and therefore rely on an underlying working computer system. Since computer technology advances with such unrelenting pace, hardware and software modules eventually become obsolete. How to preserve digital art works in these circumstances from an art preservation standpoint is much debated. In this article we discuss issues in the preservation of digital art works using as a case study a fifteen years old interactive art installation ``15 seconds of fame''. The art installation could be maintained in a good working order first just by small changes, reacting mainly to new versions of operating systems. After more then ten years a complete rewrite of the code was necessary to move it to a new computing platform.
Keywords: digital art; born-digital; art installation; interaction; art preservation; software maintenance; case study; portraits; pop-art; work in progress.
Quantitative image analysis of Tintin comics
by Gea Oswah Fatah Parikesit
Abstract: Digital image analysis is a very useful tool to perform humanities studies on various art forms, not only because it allows us to precisely quantify various parameters relevant for humanities scholars, but also because it provides us with new insights and perspectives that are not readily available from traditional qualitative methods. In this paper we demonstrate the application of this method, where we use the mean greyvalues and the number of edge pixels to represent the level of brightness and the level of visual details in the images, respectively, to characterize and identify various interesting properties of the images found in Tintin comics. Our results also indicate that this method can be used to characterize and identify different comics artists based on the visual patterns in their works.
Keywords: Digital image analysis; comics; Tintin; greyvalues; edge pixels.
Quantitative analysis of the puppet shapes in Ngayogyakarta Wayang Kulit
by Gea Oswah Fatah Parikesit
Abstract: In order to better understand and safeguard Wayang Kulit, the UNESCO-listed art of shadow theatre originated from Indonesia, a comprehensive research is necessary. In this paper we demonstrate that quantitative digital image analysis is very useful to investigate the puppet shapes in Ngayogyakarta Wayang Kulit. We found that various pairs of physical variables can be used to analyze the puppet shapes: the puppet level of details, the puppet surface area, the puppet perimeter length, and the puppet height. Our results demonstrate that we can classify the different types of puppet characters using the puppet shapes. Moreover, we can also identify which ratio of variables is kept generally constant. Our method can be generally extended to other types of puppet theatres.
Keywords: Wayang Kulit; puppet shapes; quantitative image analysis.
Towards a Unique Artistic Constitution of Light: An Aesthetic Investigation of Laser Sciences.
by Diaa Ahmedien
Abstract: This article assumed a communicative model and an informative model as two interpretative approaches to classify laser artworks. Hence, it attempted to determine how some artists struggled to build a unique constitution of laser light usage in their own revolutionary artworks and how they managed to conceptualize the scientific aspects behind the laser light and, therefore, emphasized laser art as an independent artistic trend in sciences of visual arts and as a form of advanced light arts in contemporary visual arts. By classifying the use of laser light in the arts
qualitatively and quantitatively, this study tried to elucidate how scientific developments in the physics of laser light have seriously affected the essence of the contemporary aesthetics, in which a non-traditional aspect of the relationship between art, sciences, and technology can be embodied. In addition, how can the physics of laser light contribute to a fundamentally change in the concept of light as an artistic material and medium in todays art?
Keywords: Laser Art; Holographic Art; contemporary aesthetics; sciences of visual arts; technological art.
