An adaptation framework for new media artworks

In this paper, we are interested in adaptation mechanisms for the design, creation and experimentation of adaptive and interactive new media artworks. Through a concrete case study, we propose an adaptation framework that combines semantic and physical adaptation and that can be specialized to the specific needs of various new media artists. This adaptation framework is supported by an adaptation engine, the kernel of the software architecture we are currently building. We have validated our adaptation framework through the implementation of a prototype of the adaptation engine. This prototype integrates the management of various types of metadata and allows a representation of adaptation scenarios as policies of the form event-condition-action. \ud We present how we used our adaptation engine to reconstruct and experiment the adaptation model of The Man of the Crowd, an existing adaptive new media installation, where the artist introduces a semantic adaptation of the video content displayed on four screens, according to the relative position of the viewer in the artistic installation

Design and production of new media artworks

New media artists today take advantage of, and are influenced by, the many possibilities offered by new digital technologies. They are very demanding users and a detailed examination of their practices and approaches will provide a better understanding of the usage of multimedia technologies. In this paper, we are interested in the design and creation of new media artworks. Through a concrete example, we present the different stages in the life cycle of an adaptive new media artwork and we identify the corresponding canonical processes

Process modeling for new media artworks

Practices in new media art pose very interesting challenges to the multimedia research community in terms of software tools development, usage of media technologies or documentation and conservation of new meda artworks. In this paper, we present the different stages in the life cycle of new media artworks and we illustrate the use of the canonical processes of media production in this context. This work is a first step towards a process modeling framework for the description and documentation of new media artworks

Carbohydrate Hydrolysis and Transport in the Extreme Thermoacidophile \u3ci\u3eSulfolobus solfataricus\u3c/i\u3e

Extremely thermoacidophilic microbes, such as Sulfolobus solfataricus, are strict chemoheterotrophs despite their geologic niche. To clarify their ecophysiology, the overlapping roles of endoglucanases and carbohydrate transporters were examined during growth on soluble cellodextrins as the sole carbon and energy source. Strain-specific differences in genome structure implied a unique role for one of three endogenous endoglucanases. Plasmid-based endoglucanase expression promoted the consumption of oligosaccharides, including cellohexaose (G6) through cellonanaose (G9). Protein transporters required for cellodextrin uptake were identified through mutagenesis and complementation of an ABC transporter cassette, including a putative oligosaccharide binding protein. In addition, ablation of the binding protein compromised growth on glucose and alpha-linked oligosaccharides while inactivation of a previously described glucose transporter had no apparent impact. These data demonstrate that S. solfataricus employs a redundant mechanism for soluble cellodextrin catabolism having both substrate uptake and extracytoplasmic hydrolytic components
