    Frontiers of Adaptive Design, Synthetic Biology and Growing Skins for Ephemeral Hybrid Structures

    Get PDF
    The history of membranes is one of adaptation, from the development in living organisms to man-made versions, with a great variety of uses in temporary design: clothing, building, packaging, etc. Being versatile and simple to integrate, membranes have a strong sustainability potential, through an essential use of material resources and multifunctional design, representing one of the purest cases where “design follows function.” The introduction of new engineered materials and techniques, combined with a growing interest for Nature-inspired technologies are progressively merging man-made artifacts and biological processes with a high potential for innovation. This chapter introduces, through a number of examples, the broad variety of hybrid membranes in the contest of experimental Design, Art and Architecture, categorized following two different stages of biology-inspired approach with the aim of identifying potential developments. Biomimicry, is founded on the adoption of practices from nature in architecture though imitation: solutions are observed on a morphological, structural or procedural level and copied to design everything from nanoscale materials to building technologies. Synthetic biology relies on hybrid procedures mixing natural and synthetic materials and processes

    Dreamt Spaces

    Beyond a mere interdisciplinary relationship, the symbiosis of cinema, body and architecture conveys an illusion: showing a dreamt architecture. The vision of architecture through a cinematographic filter facilitates infinite possibilities, from creating habitability conditions in impossible spaces to endowing architecture with unimaginable attributes. Aspects such as movement or dematerialization, in principle far from classic architectural values, have a familiar ring due to experiences gained in cinema. Likewise, in recent decades architecture has dared to carry out spatial experiments whose only objective is experimentation on the interrelation between body and space. Despite the importance of this question to the perception of certain architecture, during many years architects absented themselves from this field of experimentation. In the majority of the cases, as mere spectators, they limited themselves exclusively to observe the proposals of some artists and film-makers who transformed space just in another plastic material. Many of these proposals of "space alteration" were left in the dust, however, some of them established a basis for certain events to come which would change forever the traditional ways of understanding space. This new perception emerging from cinematic images poses new processes of connectivity between body and space, as we may observe in some of the works of the US Americans Diller & Scofidio, intimately related to new technologies. Others, like Philippe Rahm, focus on the fusion of biological and sensorial aspects of life forms in determinate spaces. Some like the Fabric team propose a deliberate alteration of perceiving the interior-exterior interaction of habitable spaces by means of addition and fusion. None of the above is science fiction, but we can elaborate a new architectural map with clear cinematographic references

    Non-Destructive Evaluation—A Pivotal Technology for Qualification of Composite Aircraft Structures

    Get PDF
    Tremendous advances in composite materials and a deeper understanding of their behavior have been responsible for the increased use of composites in the development of advanced, new generation civil and military aircraft. Composites play an important role in any aircraft development programme and are strong contenders to their metal counterparts due to their significant contributions towards improving strength, stiffness, fatigue properties & weight reduction. As materials, structural design & processing have evolved, strong emphasis is placed on effective & reliable damage detection, durability and damage tolerance. As a consequence, Non-destructive Evaluation (NDE) has also undergone significant advances towards meeting the growing demands of quality assurance. Advanced Composites Division (ACD) of National Aerospace Laboratories (NAL), has been involved in the development of composite structures for both civil and military aircraft for over a decade and a half. Innovative composite processing methods like co-curing/co-bonding have been successfully employed to realize airworthy structures. The role of NDE in the development of these structures has been critical and not limited to damage detection alone. On several occasions, NDE has provided valuable inputs towards improving design and process parameters. In-spite of the complexity of the structures, stringent quality requirements and tight delivery schedules, NDE has been successful in certifying these composite structures for airworthiness. This paper discusses the implementation of key NDE techniques like ultrasonics, radiography, acoustic emission and thermography for reliable flaw detection, characterization and quality assurance of composite aircraft structures

    This is the post-print version of the article. The official published version can be accessed from the link below - Copyright @ 2009 Taylor & FrancisWearable computing devices worn on the body provide the potential for digital interaction in the world. A new stage of computing technology at the beginning of the 21st Century links the personal and the pervasive through mobile wearables. The convergence between the miniaturisation of microchips (nanotechnology), intelligent textile or interfacial materials production, advances in biotechnology and the growth of wireless, ubiquitous computing emphasises not only mobility but integration into clothing or the human body. In artistic contexts one expects such integrated wearable devices to have the two-way function of interface instruments (e.g. sensor data acquisition and exchange) worn for particular purposes, either for communication with the environment or various aesthetic and compositional expressions. 'Wearable performance' briefly surveys the context for wearables in the performance arts and distinguishes display and performative/interfacial garments. It then focuses on the authors' experiments with 'design in motion' and digital performance, examining prototyping at the DAP-Lab which involves transdisciplinary convergences between fashion and dance, interactive system architecture, electronic textiles, wearable technologies and digital animation. The concept of an 'evolving' garment design that is materialised (mobilised) in live performance between partners originates from DAP Lab's work with telepresence and distributed media addressing the 'connective tissues' and 'wearabilities' of projected bodies through a study of shared embodiment and perception/proprioception in the wearer (tactile sensory processing). Such notions of wearability are applied both to the immediate sensory processing on the performer's body and to the processing of the responsive, animate environment.

    A sensing platform for physiological and contextual feedback to tennis athletes

    Get PDF
    In this paper we describe our work on creating a multi-modal sensing platform for providing feedback to tennis coaches and players. The platform includes a fixed installation around a tennis court consisting of a video camera network and a localisation system as well as wearable sensing technology deployed to individual athletes. We describe the various components of this platform and explain how we can capture synchronised multi-modal sensor data streams for games or training sessions. We then describe the content-based retrieval system we are building to facilitate the development of novel coaching tools. We provide some examples of the queries that the system can support, where these queries are chosen to be suitably expressive so as to reflect a coach's complex information needs regarding tennis-related performance factors

    Patent Pending: How Immigrants Are Reinventing the American Economy

    Get PDF
    The future of the American economy rests on our ability to innovate and invent the new products that will define the global economy in the decades ahead. This report seeks to highlight one key aspect of this challenge that is often overlooked: the crucial role that foreign scientists, engineers, and other researchers play in inventing the products and dreaming up the ideas that will power the American economy in the future. As the magnet for the world's brightest minds, America has prospered greatly from the global innovators who have come here to do research and invent products. However, many of these innovators face daunting or insurmountable immigration hurdles that force them to leave the country and take their talents elsewhere. The problem is particularly acute at our research universities, where we train the top minds, only to send them abroad to compete against us.This report aims to quantify both the role that foreign-born inventors play in the innovation coming out of US universities, and the costs we incur by training the world's top minds and sending them away. University research is responsible for 53% of all basic research in America. Much of this research leads to patented inventions, new companies, and jobs for American workers
