Industry 4.0 dictates the end of traditional centralized applications for production control. Its vision of ecosystems of smart factories with intelligent and autonomous shop-floor entities is inherently decentralized. Responding to customer demands for tailored products, these plants fueled by technology enablers such as 3D printing, Internet of Things, Cloud computing, Mobile Devices and Big Data, among others create a totally new environment. The manufacturing systems of the future, including manufacturing execution systems (MES) will have to be built to support this paradigm shift.

Background. Currently, in connection with the conduct of a special military operation, the issue of the availability of inexpensive mobile terminals for high-speed satellite communications of domestic production is very relevant, as well as due to the large extent of the territories of our country, there are a number of areas where cellular communication is absent, for example, the Taiga, the Arctic, the territory of the Arctic Ocean, etc. Therefore, the only possible connection in these territories is satellite communication. Aim. Development of a linear equidistant antenna array with equal amplitude and common-mode excitation for a mobile satellite communication terminal. Methods. The antenna array was designed from the open ends of waveguides with a cross section of 19 × 11 mm with air filling. Adjacent pairs of radiating waveguides are powered by an E-planar divider: the waveguide is divided in half in height by a thin metal diaphragm, wave reflections from which are insignificant; further, in each half of the power divider, height-separated right and left turns and smooth transitions in the E-plane are implemented – an extension from 5,25 mm to 11 mm. Results. An antenna array with a period of 19,5 mm has been developed. Overall dimensions: opening width – 624 mm, height – 12 mm, depth – 118 mm. A feature of the antenna array design is the use of smooth asymmetric transitions in the E-plane according to the exponential law; in the opening of the headlights, waveguide asymmetric horns alternate, with a period equal to 4 values of the width of the waveguides, taking into account the width of their narrow walls, expanding in the upper (2 adjacent radiators) and lower (next 2 radiators) directions. Conclusion. The advantage of using an approach to the construction of linear antenna arrays powered by multichannel power dividers is the ability to minimize the depth of the antenna system. The main disadvantages are the constructive and technological complexity of power dividers and significant power losses with a large number of channels. Possible manufacturing technologies of the developed phased array: 1. Stamping of polystyrene of the inner part of the power divider and emitters. Next, polishing, copper spraying and electroplating with a layer of copper. 2. Printing on a 3D polystyrene printer, polishing, copper spraying and copper electroplating. 3. Manufacture of a power divider using SIW technology based on standard microwave laminates. The use of metallized through holes for matching power dividers. Antenna elements and coaxial waveguide junctions are made by stamping from polystyrene, or printing on a 3D printer from polystyrene, then polishing, spraying a layer of copper and electroplating with a layer of copper. 4. Metal stamping of the power divider, emitters and coaxial waveguide junctions (2 parts). The dielectric insert can be printed on a 3D printer made of polystyrene.

Formulation of the problem. The development of modern mobile satellite communication systems dictates the need for the development of multipath antennas having: high values of the directional coefficient, low level of side lobes, a large number of scanning beams in a wide viewing sector without distortion in the azimuthal and angular planes. Multipath antenna systems based on spherical Luneberg lenses have these advantages. Despite their advantages, the spherical lenses of Luneberg did not find wide practical use due to the complexity of the design, the high cost of production, and the large mass (in some cases). Thanks to the progress in the field of artificial media, the emergence of new production methods, various designs of spherical Luneberg lenses have been developed. The use of artificial dielectrics allows you to create inexpensive, lightweight spherical Luneberg lenses. One widely used method of creating an artificial environment is to use partial air filling dielectrics. Luneberg lenses based on such media can have various designs: based on a dielectric ball with radial holes of variable diameter, from electrically small dielectric cubes of variable size, from a set of perforated dielectric disks, etc. For the manufacture of such lenses, various manufacturing technologies can be used, for example, three-dimensional printing, CNC machine. Purpose. Comparative analysis of the characteristics of two structures of the spherical Luneberg lens with the aim of working at frequencies above 9 GHz: from a set of perforated dielectric disks, from dielectric cubes of different sizes. Results. The results of comparative analysis of two designs of the spherical Luneberg lens are presented. The procedure of synthesis of each structure is considered. Design dependencies of effective dielectric constant used in development of investigated spherical lenses of Luneberg are given. Possible methods of technical implementation for each lens are considered, as well as important features that should be taken into account when designing and technical implementation. The weight of each structure was estimated. Conclusions about mechanical strength were made. Based on numerical modeling using the Weyland method, a comparison of directional properties in a wide frequency band was made. Conclusions have been drawn about the similarity and difference in directional characteristics. Practical importance. The scientific and technical results obtained in the article will be useful in choosing the design of the Luneberg lens from artificial dielectrics, depending on the specified technical requirements, and production conditions.

A design analysis is applied to six bifacial tools recovered from the Botanie Lake Dam site (EcRj 15) on the Plateau of southern British Columbia. While these artifacts, selected from the lithic assemblage of this late pre-contact period mat lodge campsite, show some internal variation, they share important characteristics indicative of their use by Plateau peoples. Acute edge angles and less durable raw material suggests that these bifacial tools were used to cut relatively soft contact materials such as herbaceous plants. Their lengthy use lives and multifunctionality make them effective solutions for the requirements of plant and animal processing during a mobile seasonal round. This application of design theory to a small sample of lithic artifacts from a seasonal camp site with an hypothesized focus on root resource harvesting and processing adds to the growing number of studies employing this approach to lithic analysis.

Introduction The concept of ‘wellbeing’ is typically thought of in human-centric ways, referring to the affective feelings and bodily sensations that people may have which inform their sense of health, safety, and connection. However, as our everyday lives, identities, relationships, and embodiments become digitised and datafied, ‘wellbeing’ has taken on new practices and meanings. The use of digital technologies such as mobile and wearable devices, social media platforms, and networks of information mediate our interactions with others, as well as the ways we conceptualise what it means to be human, including where the body begins and ends. In turn, digital health technologies and ‘wellness’ cultures such as those promoted on social media sites such as Instagram, Pinterest, YouTube, TikTok, and Facebook have also shaped our understanding of ‘wellness’ and ‘wellbeing’, their parameters, and how they ought to be practiced and felt (Baker; Lupton Digital Health; Lupton et al.). For millennia, aspects of human bodies have been documented and materialised in a variety of ways to help people understand states of health and illness: including relationships to the environments in which they lived. Indigenous and other non-Western cosmologies have long emphasised the kinds of vibrancies and distributed agencies that are part of reciprocal more-than-human ‘manifestings’ of kinships, and have called for all people to adopt the role of stewards of the ecosystem (Bawaka Country et al.; Hernández et al.; Kimmerer; Rots; Todd; Tynan). In Western cultures, ideas of the human body that reach back to ancient times adopt a perspective that viewed the continuous flows of forces (the four humours) in conjunction with the elements of air, wind, earth, and fire inside and outside the body as contributing to states of health or ill health. It was believed that good health was maintained by ensuring a balance between these factors, including acknowledgement of the role played by climactic, ecological, and celestial conditions (Hartnell; Lagay). A more-than-human approach is beginning to be re-introduced into Western cultures through political activism and academic thinking about the harms to the planet caused by human actions, including global warming and climate crises, loss of habitats and ecological biodiversity, increased incidence of extreme weather events such as bushfires, floods, and cyclones, and emerging novel pathogens affecting the health not only of humans but of other living things (Lewis; Lupton Covid Societies; Lupton Internet of Animals; Neimanis et al.). Contemporary Western more-than-human philosophers argue for the importance of acknowledging our kinship with other living and non-living things as a way of repositioning ourselves within the cosmos and working towards better health and wellbeing for the planet (Abram; Braidotti; Plumwood). As these approaches emphasise, health, wellbeing, and kinship are always imbricated within material-social assemblages of humans and non-digital things which are constantly changing, and thereby generating emergent rather than fixed capacities (Lupton "Human-Centric"; Lupton et al.). In this article, we describe our More-than-Human Wellbeing exhibition. To date, new media, Internet, and communication studies have not devoted as much attention to more-than-human theory. It is this more-than-digital and more-than-human approach to health information and wellbeing that marks out our research program as particularly distinctive. Our research focusses on the many and varied digital and non-digital forms that information about health and bodies takes. We are interested in health data as they are made and form part of the objects and activities of people’s everyday lives and aim to expand the human-centric approach offered in digital health by positioning human health and embodiment as always imbricated within more-than-human ecosystems. We acknowledge that all environments (natural and human-built) are intertwined with humans, and that to a greater or lesser extent, all are configured with and through the often exploitative and extractive practices and ideologies of those living in late modern societies in which people are positioned as superior to and autonomous from other living things. Together with more-than-human scholarship, we take inspiration from work in which arts-based, multisensory, and museum curation methods are employed to draw attention to the intertwining of people and ecologies (Endt-Jones; Howes). Our exhibition was planned as a research translation and engagement project, communicating several of our studies’ findings in arts-based media (Lupton "Embodying"). In what follows, we outline the concepts leading to the creation of our exhibits and describe how these pieces materialise and extend more-than-human concepts of wellbeing and care. Five of the exhibits we created for this exhibition are discussed. They all draw on our research findings across a range of studies, together with more-than-human theory and medical history (Lupton "More-Than-Human"). We describe how we used these pieces to materialise more-than-human concepts of health, wellbeing, and kinship in ways that we hoped would provoke critical thought, affective responses, and open capacities for action for contributing to both human and nonhuman flourishing. The background, thinking, and modes of making leading to the creation of ‘Cabinet of Human/Digital/Data Curiosities’, ‘Smartphone Fungi’, ‘Hand of Signs’, ‘Silken Anatomies’, and ‘Talking/Flowers’ are explained below. Bodily Curios Vaughan Wozniak-O’Connor and Deborah Lupton. Cabinet of Human/Digital/Data Curiosities. Reclaimed timber, found objects, resin 3D prints. 2023. Fig. 1: Cabinet of Human/Digital/Data Curiosities. Fig. 2: Detail from Cabinet of Human/Digital/Data Curiosities. The objects we have placed in Cabinet of Human/Digital/Data Curiosities (figs. 1 and 2) mix together such things from the past as prosthetic human eyeballs and teeth used in medicine and dentistry in earlier eras. This collection of found and manufactured objects, both old and new, draws on the concept of the ‘cabinet of curiosities’, also known as cabinets of wonder, which first became popular in the sixteenth century. Artefacts were assembled together for viewing in a room or a display case. The items were chosen for being notable in some way by the curator, including objects from natural history, antiquities, and religious relics, as well as works of art. These collections, purchased, curated, and assembled by members of the nobility or the wealthy as a marker of refinement, knowledge, or social status, were the precursor of museums (Endt-Jones). We see digital devices such as mobile phones as one of a multitude of ways that operate to document and preserve elements of human embodiment – indeed, as contemporary ‘cabinets of curiosities’. Our cabinet also refers to the tradition of medical museums, which display preserved human organs, body parts, and tissue in glass bottles for pedagogical purposes. Under this model of health, specimens of both ‘ideal’ health and also ‘ill’ health – abnormalities in the flesh – were documented as a means of categorising wellbeing. Museums such as these would often treat diseased and disabled bodies as oddities and artefacts of ‘curiosity’. In this work, we reimagine and wind back this way of thinking, through displaying and drawing attention and curiosity towards signs of the body and the everyday. We are showing that wellbeing is more than a process of categorisation, comparison, or measurement of ‘ideal’ or ‘abnormal’; it is in the traces we leave behind us when we return to the earth. Our information data are human remains, moving as endless constellations of the interior and exterior of the body (Lupton Data Selves). In this artwork, both reclaimed wood and 3D-printed resin were used as a synergy between the natural and synthetic. Taking our cue from the manner of display of these items in medical museums, we have added our own curios, including 3D-printed body organs sprouting fungi (fig. 2), as a way of demonstrating the entanglements between humans and the fungal kingdom. Interspersed among these relics of human bodies is a discarded mobile phone with its screen badly shattered. It is displayed as a more recent antiquated object for making images and collecting, storing, and displaying information and images about human bodies, which itself is subject to disastrous events despite its original high-tech veneer of glossy impermeability. Technologies are more-than-flesh as human-made simulacra of body parts. Our wellbeing is sensed and made sense of through bodies’ entanglements of human and nonhuman. These curios both materialise traces of our bodies and wellbeing and extend our bodies into the physical spaces we inhabit and through which we move. Reading the Traces and Signs Vaughan Wozniak-O’Connor and Deborah Lupton. Smartphone Fungi. Recycled European oak, 3D printed resin, CNC carved plywood. 2023 Vaughan Wozniak-O’Connor and Deborah Lupton. Hand of Signs. Laser-etched walnut and plywood. 2023. Fig. 3: Smartphone Fungi. / Fig. 4: Detail from Smartphone Fungi. Wellbeing is also a process of mark-making, realised through the reciprocal impressions we leave on each other and the world around us. In Smart Phone Fungi (figs. 3 and 4) we capture the idea of ‘recording’ that takes place between people, technologies, and the natural world. It was inspired by a huge tree which members of our team noticed on a bush walk in the Blue Mountains, near Sydney, Australia. Growing from this tree were fungi of similar size and shape to the smartphone that was used to capture the image. In our interpretation, a piece of reclaimed timber was used to represent the tree, itself marked by its human use, and fungal shapes replicating those on the tree were produced using computer numerical controlled (CNC) carving. The central timber post is covered with human and more-than-human traces, such as old tool marks, weather damage, and wood borer holes. Alongside these traces, the CNC-carved fungi forms add a conspicuously digital layer of human intervention. Fig. 5: Hand of Signs. In Hand of Signs (fig. 5), we extend this idea of both organic and digital data traces as something that can be ‘read’ or interpreted. Inspired by the practice of palmistry, this work re-interprets line reading, the historical wooden anatomical model, and human body scanning as ways of reading for signs of wellbeing in past and future. Palm readers interpret people’s character, health, longevity, and other aspects of their lives through the creases and traces of development, wear, and deteriorations in the skin of our hands (Chinn). Life leaves its traces on our palms. The piece also refers to the newer tradition of digitising human bodies (Lupton Quantified Self; Lupton et al.), employing scanning and data visualising technologies, which uses spatial GPS data to deduce patterns of human activity. For both palmistry and in more contemporary monitoring technologies, one’s wellbeing can be deduced through the map: the lines of the palm and the errant traces collected by satellites and sensors. To reflect this relation between mapping and palmistry, our updated anatomical model references both the contours of 3D geospatial data and of the human palm. However, this piece looks to represent more layers of data beyond those captured by GPS data. By using reclaimed wood to construct this human hand model, we are again making an analogy between the marks of growth and life that timber displays and those that the human body bears and develops as people move through more-than-worlds throughout their lifespans. The piece also seeks to draw attention to the various ‘signs’ that have been used across centuries to interpret the current and future health and wellbeing of humans (once markings on or morphologies of the body, now often the digitised visualisations of the internal operations and physical movements of the body that are generated by digital health technologies), superimposing older and newer modes of corporeal knowledge. Layers of Mediation Megan Rose. Silken Anatomies. Digital print on satin and yoryu silk chiffon. 2023. Ash Watson. Talking/Flowers. Collage and digital inkjet on paper. 2023. Fig. 6: Detail from Silken Anatomies. The ways that we come to sense and understand wellbeing are also mediated through the reproductive interplay of natural and technological elements. Silken Anatomies (fig. 6) was inspired by anatomical prints from the Renaissance showing details of the interiors of human bodies and organs together with living things and objects from the natural world. These webs of interconnectivity were thought to be key to wellbeing and health. Produced at scale through metal engraving and woodblock printing, these natural history and compendia took on major importance as part of these educational resources (Kemp; Swan). In an effort to extend the reach of artefacts beyond their tangible presence, libraries globally have sought to create open access digital scans of historic medical and botanical illustrations. The images reconfigured in Silken Anatomies were downloaded from the Wellcome Trust’s online archive and have been reimagined through digital enhancement and sublimation dye techniques. Referencing shrouds, the yoryu silk panels enfold exhibition visitors, who were able to touch and pass through the silks, causing them to billow in response to human movement. We bring together an animal-made material (crafted by silkworms) with more-than-human images featuring both humans and other living creatures. The vibrancies of these beautifully engraved and coloured anatomical images are given a new life and a new feel, both affectively and sensuously, through this piece. We can both see and touch these more-than-human illustrations that speak to us of the early modern natural science visualisations that underpin contemporary digital images of the human body and the more-than-human world. The vibrancies of these beautifully engraved and coloured anatomical plates are given a new life and a new feel, both affectively and sensuously. The digital is returned to the tangible. Fig. 7: Detail from Talking/Flowers. Even in increasingly digitised healthcare environments, paper and other printed materials remain central documents in the landscape of health and wellbeing. Zines are small-scale, DIY, and typically handcrafted publications, which are often made to express creators’ thoughts and feelings about health and wellbeing (Lupton "Health Zines"; Watson and Bennett). Talking/Flowers (fig. 7), a zine of visual and textual work, explores the materialities of health information and healthcare encounters by creatively layering a diverse range of materials: clippings from MRI scans, digitally warped and recoloured images from medical infographics, and found poetry made from research publications. In this way, the zine remixes and reconstitutes key documents of authority in health institutions which continue to take primacy as evidence. While vital in the pipeline of diagnosis and treatment, such documents can become black boxes of meaning, and serve to distance health professionals from consumers and consumers from agentic understandings of their own health. These evidentiary materials are brought together here with other imagery, textures, and recollections of personal experience; the pages also feature leaves, flowers, fungi, and oceanic tones. Oceans, pools, rivers, lakes, and other coastal forms or waterways offer all-consuming sensory spaces in which people can find calm, balance, buoyancy, and connection with the wider world. Aqua tides, purple eddies, and misshapen pearls flow through the pages as the golden thread of the zine’s aesthetic theme. Also featured are three original poems. The first and third poems, ‘talking to a doctor’ and ‘talking to other people’, explore moments of relational vulnerability. The second poem, ‘untitled’, is a found poem made from the conclusions of sociologist Talcott Parsons’s 1975 article on the sick role reconsidered. In each of these poems, information and communication jar the encounters and more-than-human metaphors hold space for complex feelings. The cover similarly merges imagery from botanical and historical medical illustrations with a silver shell, evoking the morphological dimensions that connect the more-than-human. Exhibition visitors were able to turn the pages of the original copy of the zine, and were invited to take a printed copy away with them. Conclusion More-than-Human Wellbeing is an exhibition which aims to expand the horizons of how we understand wellbeing and our entanglements with the world. Our exhibition was designed to draw on our research into the more-than-human dimensions of health and wellbeing in the context of an increasingly digitised and datafied world. We wanted to attune visitors to the relational connections and multisensory ways of knowing that develop with and through people’s encounters and entanglements with creatures, things, and spaces. We sought to demonstrate that in this digital age, in which digital devices and software are often considered the most accurate and insightful ways to monitor and measure health and wellbeing, multisensory and affective engagements with elements of the natural environment remain crucial to understanding our bodies and health. Through engagements with our artworks, we hoped that new capacities for visitors’ learning and thinking about the relational and distributed dimensions of more-than-human wellbeing would be opened. While traditionally thought of as human-centered, we explore human health and wellbeing as interconnected with both the natural and technological. We used materials from the natural world – timber, paper materials, and silk fabric – in our artworks to capture both the multigenerational traces and entanglements between humans and plant matter. Recent works of natural and cultural history have drawn attention to the mysterious and important worlds of the fungi kingdom and its role in supporting and living symbiotically with other life on earth, including humans as well as plants (Sheldrake; Tsing). We also made sure to acknowledge this third kingdom of living things in our artworks. We combined these images and materials from nature with digitised modes of printing and fabrication to highlight the intersections of the digital with the non-digital in representations and sensory feelings of health and wellbeing. We disrupt and make strange signs of traditional human-centric medicine through reconfigurations, bricolage, and re-imaginations of more-than-human wellbeing. As humans we are interconnected with the natural world, and the signs of these meetings can be traced and read. Through our artistic creations, we hope to re-orient people towards this more open way of thinking about wellbeing. Working with arts practices and creative data visualisations, both digital and analogue, we bring to the fore the role that more-than-human agents play in mediating and making these convivial more-than-digital connections.

Introduction Many destinations promote culinary encounters. Foods and beverages, and especially how these will taste in situ, are being marketed as niche travel motivators and used in destination brand building across the globe. While initial usage of the term culinary tourism focused on experiencing exotic cultures of foreign destinations by sampling unfamiliar food and drinks, the term has expanded to embrace a range of leisure travel experiences where the aim is to locate and taste local specialities as part of a pleasurable, and hopefully notable, culinary encounter (Wolf). Long’s foundational work was central in developing the idea of culinary tourism as an active endeavor, suggesting that via consumption, individuals construct unique experiences. Ignatov and Smith’s literature review-inspired definition confirms the nature of activity as participatory, and adds consuming food production skills—from observing agriculture and local processors to visiting food markets and attending cooking schools—to culinary purchases. Despite importing almost all of its foodstuffs and beverages, including some of its water, Singapore is an acknowledged global leader in culinary tourism. Horng and Tsai note that culinary tourism conceptually implies that a transferal of “local or special knowledge and information that represent local culture and identities” (41) occurs via these experiences. This article adds the act of reading to these participatory activities and suggests that, because food writing forms an important component of Singapore’s suite of culinary tourism offerings, taste contributes to the cultural experience offered to both visitors and locals. While Singapore foodways have attracted significant scholarship (see, for instance, work by Bishop; Duruz; Huat & Rajah; Tarulevicz, Eating), Singapore food writing, like many artefacts of popular culture, has attracted less notice. Yet, this writing is an increasingly visible component of cultural production of, and about, Singapore, and performs a range of functions for locals, tourists and visitors before they arrive. Although many languages are spoken in Singapore, English is the national language (Alsagoff) and this study focuses on food writing in English. Background Tourism comprises a major part of Singapore’s economy, with recent figures detailing that food and beverage sales contribute over 10 per cent of this revenue, with spend on culinary tours and cookery classes, home wares such as tea-sets and cookbooks, food magazines and food memoirs additional to this (Singapore Government). This may be related to the fact that Singapore not only promotes food as a tourist attraction, but also actively promotes itself as an exceptional culinary destination. The Singapore Tourism Board (STB) includes food in its general information brochures and websites, and its print, television and cinema commercials (Huat and Rajah). It also mounts information-rich campaigns both abroad and inside Singapore. The 2007 ‘Singapore Seasons’ campaign, for instance, promoted Singaporean cuisine alongside films, design, books and other cultural products in London, New York and Beijing. Touring cities identified as key tourist markets in 2011, the ‘Singapore Takeout’ pop-up restaurant brought the taste of Singaporean foods into closer focus. Singaporean chefs worked with high profile locals in its kitchen in a custom-fabricated shipping container to create and demonstrate Singaporean dishes, attracting public and media interest. In country, the STB similarly actively promotes the tastes of Singaporean foods, hosting the annual World Gourmet Summit (Chaney and Ryan) and Pacific Food Expo, both attracting international culinary professionals to work alongside local leaders. The Singapore Food Festival each July is marketed to both locals and visitors. In these ways, the STB, as well as providing events for visitors, is actively urging Singaporeans to proud of their food culture and heritage, so that each Singaporean becomes a proactive ambassador of their cuisine. Singapore Food Writing Popular print guidebooks and online guides to Singapore pay significantly more attention to Singaporean food than they do for many other destinations. Sections on food in such publications discuss at relative length the taste of Singaporean food (always delicious) as well as how varied, authentic, hygienic and suited-to-all-budgets it is. These texts also recommend hawker stalls and food courts alongside cafés and restaurants (Henderson et al.), and a range of other culinary experiences such as city and farm food tours and cookery classes. This writing describes not only what can be seen or learned during these experiences, but also what foods can be sampled, and how these might taste. This focus on taste is reflected in the printed materials that greet the in-bound tourist at the airport. On a visit in October 2013, arrival banners featuring mouth-watering images of local specialities such as chicken rice and chilli crab marked the route from arrival to immigration and baggage collection. Even advertising for a bank was illustrated with photographs of luscious-looking fruits. The free maps and guidebooks available featured food-focused tours and restaurant locations, and there were also substantial free booklets dedicated solely to discussing local delicacies and their flavours, plus recommended locations to sample them. A website and free mobile app were available that contain practical information about dishes, ingredients, cookery methods, and places to eat, as well as historical and cultural information. These resources are also freely distributed to many hotels and popular tourist destinations. Alongside organising food walks, bus tours and cookery classes, the STB also recommends the work of a number of Singaporean food writers—principally prominent Singapore food bloggers, reviewers and a number of memoirists—as authentic guides to what are described as unique Singaporean flavours. The strategies at the heart of this promotion are linking advertising to useful information. At a number of food centres, for instance, STB information panels provide details about both specific dishes and Singapore’s food culture more generally (Henderson et al.). This focus is apparent at many tourist destinations, many of which are also popular local attractions. In historic Fort Canning Park, for instance, there is a recreation of Raffles’ experimental garden, established in 1822, where he grew the nutmeg, clove and other plants that were intended to form the foundation for spice plantations but were largely unsuccessful (Reisz). Today, information panels not only indicate the food plants’ names and how to grow them, but also their culinary and medicinal uses, recipes featuring them and the related food memories of famous Singaporeans. The Singapore Botanic Gardens similarly houses the Ginger Garden displaying several hundred species of ginger and information, and an Eco(-nomic/logical) Garden featuring many food plants and their stories. In Chinatown, panels mounted outside prominent heritage brands (often still quite small shops) add content to the shopping experience. A number of museums profile Singapore’s food culture in more depth. The National Museum of Singapore has a permanent Living History gallery that focuses on Singapore’s street food from the 1950s to 1970s. This display includes food-related artefacts, interactive aromatic displays of spices, films of dishes being made and eaten, and oral histories about food vendors, all supported by text panels and booklets. Here food is used to convey messages about the value of Singapore’s ethnic diversity and cross-cultural exchanges. Versions of some of these dishes can then be sampled in the museum café (Time Out Singapore). The Peranakan Museum—which profiles the unique hybrid culture of the descendants of the Chinese and South Indian traders who married local Malay women—shares this focus, with reconstructed kitchens and dining rooms, exhibits of cooking and eating utensils and displays on food’s ceremonial role in weddings and funerals all supported with significant textual information. The Chinatown Heritage Centre not only recreates food preparation areas as a vivid indicator of poor Chinese immigrants’ living conditions, but also houses The National Restaurant of Singapore, which translates this research directly into meals that recreate the heritage kopi tiam (traditional coffee shop) cuisine of Singapore in the 1930s, purposefully bringing taste into the service of education, as its descriptive menu states, “educationally delighting the palate” (Chinatown Heritage Centre). These museums recognise that shopping is a core tourist activity in Singapore (Chang; Yeung et al.). Their gift- and bookshops cater to the culinary tourist by featuring quality culinary products for sale (including, for instance, teapots and cups, teas, spices and traditional sweets, and other foods) many of which are accompanied by informative tags or brochures. At the centre of these curated, purchasable collections are a range written materials: culinary magazines, cookbooks, food histories and memoirs, as well as postcards and stationery printed with recipes. Food Magazines Locally produced food magazines cater to a range of readerships and serve to extend the culinary experience both in, and outside, Singapore. These include high-end gourmet, luxury lifestyle publications like venerable monthly Wine & Dine: The Art of Good Living, which, in in print for almost thirty years, targets an affluent readership (Wine & Dine). The magazine runs features on local dining, gourmet products and trends, as well as international epicurean locations and products. Beautifully illustrated recipes also feature, as the magazine declares, “we’ve recognised that sharing more recipes should be in the DNA of Wine & Dine’s editorial” (Wine & Dine). Appetite magazine, launched in 2006, targets the “new and emerging generation of gourmets—foodies with a discerning and cosmopolitan outlook, broad horizons and a insatiable appetite” (Edipresse Asia) and is reminiscent in much of its styling of New Zealand’s award-winning Cuisine magazine. Its focus is to present a fresh approach to both cooking at home and dining out, as readers are invited to “Whip up the perfect soufflé or feast with us at the finest restaurants in Singapore and around the region” (Edipresse Asia). Chefs from leading local restaurants are interviewed, and the voices of “fellow foodies and industry watchers” offer an “insider track” on food-related news: “what’s good and what’s new” (Edipresse Asia). In between these publications sits Epicure: Life’s Refinements, which features local dishes, chefs, and restaurants as well as an overseas travel section and a food memories column by a featured author. Locally available ingredients are also highlighted, such as abalone (Cheng) and an interesting range of mushrooms (Epicure). While there is a focus on an epicurean experience, this is presented slightly more casually than in Wine & Dine. Food & Travel focuses more on home cookery, but each issue also includes reviews of Singapore restaurants. The bimonthly bilingual (Chinese and English) Gourmet Living features recipes alongside a notable focus on food culture—with food history columns, restaurant reviews and profiles of celebrated chefs. An extensive range of imported international food magazines are also available, with those from nearby Malaysia and Indonesia regularly including articles on Singapore. Cookbooks These magazines all include reviews of cookery books including Singaporean examples – and some feature other food writing such as food histories, memoirs and blogs. These reviews draw attention to how many Singaporean cookbooks include a focus on food history alongside recipes. Cookery teacher Yee Soo Leong’s 1976 Singaporean Cooking was an early example of cookbook as heritage preservation. This 1976 book takes an unusual view of ‘Singaporean’ flavours. Beginning with sweet foods—Nonya/Singaporean and western cakes, biscuits, pies, pastries, bread, desserts and icings—it also focuses on both Singaporean and Western dishes. This text is also unusual as there are only 6 lines of direct authorial address in the author’s acknowledgements section. Expatriate food writer Wendy Hutton’s Singapore Food, first published in 1979, reprinted many times after and revised in 2007, has long been recognised as one of the most authoritative titles on Singapore’s food heritage. Providing an socio-historical map of Singapore’s culinary traditions, some one third of the first edition was devoted to information about Singaporean multi-cultural food history, including detailed profiles of a number of home cooks alongside its recipes. Published in 1980, Kenneth Mitchell’s A Taste of Singapore is clearly aimed at a foreign readership, noting the variety of foods available due to the racial origins of its inhabitants. The more modest, but equally educational in intent, Hawkers Flavour: A Guide to Hawkers Gourmet in Malaysia and Singapore (in its fourth printing in 1998) contains a detailed introductory essay outlining local food culture, favourite foods and drinks and times these might be served, festivals and festive foods, Indian, Indian Muslim, Chinese, Nyonya (Chinese-Malay), Malay and Halal foods and customs, followed with a selection of recipes from each. More contemporary examples of such information-rich cookbooks, such as those published in the frequently reprinted Periplus Mini Cookbook series, are sold at tourist attractions. Each of these modestly priced, 64-page, mouthwateringly illustrated booklets offer framing information, such as about a specific food culture as in the Nonya kitchen in Nonya Favourites (Boi), and explanatory glossaries of ingredients, as in Homestyle Malay Cooking (Jelani). Most recipes include a boxed paragraph detailing cookery or ingredient information that adds cultural nuance, as well as trying to describe tastes that the (obviously foreign) intended reader may not have encountered. Malaysian-born Violet Oon, who has been called the Julia Child of Singapore (Bergman), writes for both local and visiting readers. The FOOD Paper, published monthly for a decade from January 1987 was, she has stated, then “Singapore’s only monthly publication dedicated to the CSF—Certified Singapore Foodie” (Oon, Violet Oon Cooks 7). Under its auspices, Oon promoted her version of Singaporean cuisine to both locals and visitors, as well as running cookery classes and culinary events, hosting her own television cooking series on the Singapore Broadcasting Corporation, and touring internationally for the STB as a ‘Singapore Food Ambassador’ (Ahmad; Kraal). Taking this representation of flavor further, Oon has also produced a branded range of curry powders, spices, and biscuits, and set up a number of food outlets. Her first cookbook, World Peranakan Cookbook, was published in 1978. Her Singapore: 101 Meals of 1986 was commissioned by the STB, then known as the Singapore Tourist Promotion Board. Violet Oon Cooks, a compilation of recipes from The FOOD Paper, published in 1992, attracted a range of major international as well as Singaporean food sponsors, and her Timeless Recipes, published in 1997, similarly aimed to show how manufactured products could be incorporated into classic Singaporean dishes cooked at home. In 1998, Oon produced A Singapore Family Cookbook featuring 100 dishes. Many were from Nonya cuisine and her following books continued to focus on preserving heritage Singaporean recipes, as do a number of other nationally-cuisine focused collections such as Joyceline Tully and Christopher Tan’s Heritage Feasts: A Collection of Singapore Family Recipes. Sylvia Tan’s Singapore Heritage Food: Yesterday’s Recipes for Today’s Cooks, published in 2004, provides “a tentative account of Singapore’s food history” (5). It does this by mapping the various taste profiles of six thematically-arranged chronologically-overlapping sections, from the heritage of British colonialism, to the uptake of American and Russia foods in the Snackbar era of the 1960s and the use of convenience flavoring ingredients such as curry pastes, sauces, dried and frozen supermarket products from the 1970s. Other Volumes Other food-themed volumes focus on specific historical periods. Cecilia Leong-Salobir’s Food Culture in Colonial Asia: A Taste of Empire discusses the “unique hybrid” (1) cuisine of British expatriates in Singapore from 1858 to 1963. In 2009, the National Museum of Singapore produced the moving Wong Hong Suen’s Wartime Kitchen: Food and Eating in Singapore 1942–1950. This details the resilience and adaptability of both diners and cooks during the Japanese Occupation and in post-war Singapore, when shortages stimulated creativity. There is a centenary history of the Cold Storage company which shipped frozen foods all over south east Asia (Boon) and location-based studies such as Annette Tan’s Savour Chinatown: Stories Memories & Recipes. Tan interviewed hawkers, chefs and restaurant owners, working from this information to write both the book’s recipes and reflect on Chinatown’s culinary history. Food culture also features in (although it is not the main focus) more general book-length studies such as educational texts such as Chew Yen Fook’s The Magic of Singapore and Melanie Guile’s Culture in Singapore (2000). Works that navigate both spaces (of Singaporean culture more generally and its foodways) such Lily Kong’s Singapore Hawker Centres: People, Places, Food, provide an consistent narrative of food in Singapore, stressing its multicultural flavours that can be enjoyed from eateries ranging from hawker stalls to high-end restaurants that, interestingly, that agrees with that promulgated in the food writing discussed above. Food Memoirs and Blogs Many of these narratives include personal material, drawing on the author’s own food experiences and taste memories. This approach is fully developed in the food memoir, a growing sub-genre of Singapore food writing. While memoirs by expatriate Singaporeans such as Cheryl Lu-Lien Tan’s A Tiger in the Kitchen: A Memoir of Food and Family, produced by major publisher Hyperion in New York, has attracted considerable international attention, it presents a story of Singapore cuisine that agrees with such locally produced texts as television chef and food writer Terry Tan’s Stir-fried and Not Shaken: A Nostalgic Trip Down Singapore’s Memory Lane and the food memoir of the Singaporean chef credited with introducing fine Malay dining to Singapore, Aziza Ali’s Sambal Days, Kampong Cuisine, published in Singapore in 2013 with the support of the National Heritage Board. All these memoirs are currently available in Singapore in both bookshops and a number of museums and other attractions. While underscoring the historical and cultural value of these foods, all describe the unique flavours of Singaporean cuisine and its deliciousness. A number of prominent Singapore food bloggers are featured in general guidebooks and promoted by the STB as useful resources to dining out in Singapore. One of the most prominent of these is Leslie Tay, a medical doctor and “passionate foodie” (Knipp) whose awardwinning ieatŸishootŸipost is currently attracting some 90,000 unique visitors every month and has had over 20,000 million hits since its launch in 2006. An online diary of Tay’s visits to hundreds of Singaporean hawker stalls, it includes descriptions and photographs of meals consumed, creating accumulative oral culinary histories of these dishes and those who prepared them. These narratives have been reorganised and reshaped in Tay’s first book The End of Char Kway Teow and Other Hawker Mysteries, where each chapter tells the story of one particular dish, including recommended hawker stalls where it can be enjoyed. Ladyironchef.com is a popular food and travel site that began as a blog in 2007. An edited collection of reviews of eateries and travel information, many by the editor himself, the site features lists of, for example, the best cafes (LadyIronChef “Best Cafes”), eateries at the airport (LadyIronChef “Guide to Dining”), and hawker stalls (Lim). While attesting to the cultural value of these foods, many articles also discuss flavour, as in Lim’s musings on: ‘how good can chicken on rice taste? … The glistening grains of rice perfumed by fresh chicken stock and a whiff of ginger is so good you can even eat it on its own’. Conclusion Recent Singapore food publishing reflects this focus on taste. Tay’s publisher, Epigram, growing Singaporean food list includes the recently released Heritage Cookbooks Series. This highlights specialist Singaporean recipes and cookery techniques, with the stated aim of preserving tastes and foodways that continue to influence Singaporean food culture today. Volumes published to date on Peranakan, South Indian, Cantonese, Eurasian, and Teochew (from the Chaoshan region in the east of China’s Guangdong province) cuisines offer both cultural and practical guides to the quintessential dishes and flavours of each cuisine, featuring simple family dishes alongside more elaborate special occasion meals. In common with the food writing discussed above, the books in this series, although dealing with very different styles of cookery, contribute to an overall impression of the taste of Singapore food that is highly consistent and extremely persuasive. This food writing narrates that Singapore has a delicious as well as distinctive and interesting food culture that plays a significant role in Singaporean life both currently and historically. It also posits that this food culture is, at the same time, easily accessible and also worthy of detailed consideration and discussion. In this way, this food writing makes a contribution to both local and visitors’ appreciation of Singaporean food culture.

Our culture abhors the world.Yet Quicksand is swallowing the duellists; the river is threatening the fighter: earth, waters and climate, the mute world, the voiceless things once placed as a decor surrounding the usual spectacles, all those things that never interested anyone, from now on thrust themselves brutally and without warning into our schemes and manoeuvres (Michel Serres, The Natural Contract, p 3). When Michel Serres describes culture's abhorrence of the world in the opening pages of The Natural Contract he draws our attention to the sidelining of nature in histories and theories that have sought to describe Western culture. As Serres argues, cultural histories are quite often built on the debates and struggles of humanity, which are largely held apart from their natural surroundings, as if on a stage, "purified of things" (3). But, as he is at pains to point out, human activity and conflict always take place within a natural milieu, a space of quicksand, swelling rivers, shifting earth, and atmospheric turbulence. Recently, via the potential for vast environmental change, what was once thought of as a staid “nature” has reasserted itself within culture. In this paper I explore how Serres’s positioning of nature can be understood amid new communication systems, which, via the apparent dematerialization of messages, seems to have further removed culture from nature. From here, I focus on a set of artworks that work against this division, reformulating the connection between information, a topic usually considered in relation to media and anthropic communication (and something about which Serres too has a great deal to say), and nature, an entity commonly considered beyond human contrivance. In particular, I explore how information visualisation and sonification has been used to give a new sense of materiality to the atmosphere, repotentialising the air as a natural and informational entity. The Natural Contract argues for the legal legitimacy of nature, a natural contract similar in standing to Rousseau’s social contract. Serres’ss book explores the history and notion of a “legal person”, arguing for a linking of the scientific view of the world and the legal visions of social life, where inert objects and living beings are considered within the same legal framework. As such The Natural Contract does not deal with ecology per-se, but instead focuses on an argument for the inclusion of nature within law (Serres, “A Return” 131). In a drastic reconfiguring of the subject/object relationship, Serres explains how the space that once existed as a backdrop for human endeavour now seems to thrust itself directly into history. "They (natural events) burst in on our culture, which had never formed anything but a local, vague, and cosmetic idea of them: nature" (Serres, The Natural Contract 3). In this movement, nature does not simply take on the role of a new object to be included within a world still dominated by human subjects. Instead, human beings are understood as intertwined with a global system of turbulence that is both manipulated by them and manipulates them. Taking my lead from Serres’s book, in this paper I begin to explore the disconnections and reconnections that have been established between information and the natural environment. While I acknowledge that there is nothing natural about the term “nature” (Harman 251), I use the term to designate an environment constituted by the systematic processes of the collection of entities that are neither human beings nor human crafted artefacts. As the formation of cultural systems becomes demarcated from these natural objects, the scene is set for the development of culturally mediated concepts such as “nature” and “wilderness,” as entities untouched and unspoilt by cultural process (Morton). On one side of the divide the complex of communication systems is situated, on the other is situated “nature”. The restructuring of information flows due to developments in electronic communication has ostensibly removed messages from the medium of nature. Media is now considered within its own ecology (see Fuller; Strate) quite separate from nature, except when it is developed as media content (see Cubitt; Murray; Heumann). A separation between the structures of media ecologies and the structures of natural ecologies has emerged over the history of electronic communication. For instance, since the synoptic media theory of McLuhan it has been generally acknowledged that the shift from script to print, from stone to parchment, and from the printing press to more recent developments such as the radio, telephone, television, and Web2.0, have fundamentally altered the structure and effects of human relationships. However, these developments – “the extensions of man” (McLuhan)— also changed the relationship between society and nature. Changes in communications technology have allowed people to remain dispersed, as ideas, in the form of electric currents or pulses of light travel vast distances and in diverse directions, with communication no longer requiring human movement across geographic space. Technologies such as the telegraph and the radio, with their ability to seemingly dematerialize the media of messages, reformulated the concept of communication into a “quasi-physical connection” across the obstacles of time and space (Clarke, “Communication” 132). Prior to this, the natural world itself was the medium through which information was passed. Rather than messages transmitted via wires, communication was associated with the transport of messages through the world via human movement, with the materiality of the medium measured in the time it took to cover geographic space. The flow of messages followed trade flows (Briggs and Burke 20). Messages moved along trails, on rail, over bridges, down canals, and along shipping channels, arriving at their destination as information. More recently however, information, due to its instantaneous distribution and multiplication across space, seems to have no need for nature as a medium. Nature has become merely a topic for information, as media content, rather than as something that takes part within the information system itself. The above example illustrates a separation between information exchange and the natural environment brought about by a set of technological developments. As Serres points out, the word “media” is etymologically related to the word “milieu”. Hence, a theory of media should be always related to an understanding of the environment (Crocker). But humans no longer need to physically move through the natural world to communicate, ideas can move freely from region to region, from air-conditioned room to air-conditioned room, relatively unimpeded by natural forces or geographic distance. For a long time now, information exchange has not necessitated human movement through the natural environment and this has consequences for how the formation of culture and its location in (or dislocation from) the natural world is viewed. A number of artists have begun questioning the separation between media and nature, particularly concerning the materiality of air, and using information to provide new points of contact between media and the atmosphere (for a discussion of the history of ecoart see Wallen). In Eclipse (2009) (fig. 1) for instance, an internet based work undertaken by the collective EcoArtTech, environmental sensing technology and online media is used experimentally to visualize air pollution. EcoArtTech is made up of the artist duo Cary Peppermint and Leila Nadir and since 2005 they have been inquiring into the relationship between digital technology and the natural environment, particularly regarding concepts such as “wilderness”. In Eclipse, EcoArtTech garner photographs of American national parks from social media and photo sharing sites. Air quality data gathered from the nearest capital city is then inputted into an algorithm that visibly distorts the image based on the levels of particle pollution detected in the atmosphere. The photographs that circulate on photo sharing sites such as Flickr—photographs that are usually rather banal in their adherence to a history of wilderness photography—are augmented by the environmental pollution circulating in nearby capital cities. Figure 1: EcoArtTech, Eclipse (detail of screenshot), 2009 (Internet-based work available at:http://turbulence.org/Works/eclipse/) The digital is often associated with the clean transmission of information, as packets of data move from a server, over fibre optic cables, to be unpacked and re-presented on a computer's screen. Likewise, the photographs displayed in Eclipse are quite often of an unspoilt nature, containing no errors in their exposure or focus (most probably because these wilderness photographs were taken with digital cameras). As the photographs are overlaid with information garnered from air quality levels, the “unspoilt” photograph is directly related to pollution in the natural environment. In Eclipse the background noise of “wilderness,” the pollution in the air, is reframed as foreground. “We breathe background noise…Background noise is the ground of our perception, absolutely uninterrupted, it is our perennial sustenance, the element of the software of all our logic” (Serres, Genesis 7). Noise is activated in Eclipse in a similar way to Serres’s description, as an indication of the wider milieu in which communication takes place (Crocker). Noise links the photograph and its transmission not only to the medium of the internet and the glitches that arise as information is circulated, but also to the air in the originally photographed location. In addition to noise, there are parallels between the original photographs of nature gleaned from photo sharing sites and Serres’s concept of a history that somehow stands itself apart from the effects of ongoing environmental processes. By compartmentalising the natural and cultural worlds, both the historiography that Serres argues against and the wilderness photograph produces a concept of nature that is somehow outside, behind, or above human activities and the associated matter of noise. Eclipse, by altering photographs using real-time data, puts the still image into contact with the processes and informational outputs of nature. Air quality sensors detect pollution in the atmosphere and code these atmospheric processes into computer readable information. The photograph is no longer static but is now open to continual recreation and degeneration, dependent on the coded value of the atmosphere in a given location. A similar materiality is given to air in a public work undertaken by Preemptive Media, titled Areas Immediate Reading (AIR) (fig. 2). In this project, Preemptive Media, made up of Beatriz da Costa, Jamie Schulte and Brooke Singer, equip participants with instruments for measuring air quality as they walked around New York City. The devices monitor the carbon monoxide (CO), nitrogen oxides (NOx) or ground level ozone (O3) levels that are being breathed in by the carrier. As Michael Dieter has pointed out in his reading of the work, the application of sensing technology by Preemptive Media is in distinct contrast to the conventional application of air quality monitoring, which usually takes the form of extremely high resolution located devices spread over great distances. These larger air monitoring networks tend to present the value garnered from a large expanse of the atmosphere that covers individual cities or states. The AIR project, in contrast, by using small mobile sensors, attempts to put people in informational contact with the air that they are breathing in their local and immediate time and place, and allows them to monitor the small parcels of atmosphere that surround other users in other locations (Dieter). It thus presents many small and mobile spheres of atmosphere, inhabited by individuals as they move through the city. In AIR we see the experimental application of an already developed technology in order to put people on the street in contact with the atmospheres that they are moving through. It gives a new informational form to the “vast but invisible ocean of air that surrounds us and permeates us” (Ihde 3), which in this case is given voice by a technological apparatus that converts the air into information. The atmosphere as information becomes less of a vague background and more of a measurable entity that ingresses into the lives and movements of human users. The air is conditioned by information; the turbulent and noisy atmosphere has been converted via technology into readable information (Connor 186-88). Figure 2: Preemptive Media, Areas Immediate Reading (AIR) (close up of device), 2011 Throughout his career Serres has developed a philosophy of information and communication that may help us to reframe the relationship between the natural and cultural worlds (see Brown). Conventionally, the natural world is understood as made up of energy and matter, with exchanges of energy and the flows of biomass through food webs binding ecosystems together (DeLanda 120-1). However, the tendencies and structures of natural systems, like cultural systems, are also dependent on the communication of information. It is here that Serres provides us with a way to view natural and cultural systems as connected by a flow of energy and information. He points out that in the wake of Claude Shannon’s famous Mathematical Theory of Communication it has been possible to consider the relationship between information and thermodynamics, at least in Shannon’s explanation of noise as entropy (Serres, Hermes74). For Serres, an ecosystem can be conceptualised as an informational and energetic system: “it receives, stores, exchanges, and gives off both energy and information in all forms, from the light of the sun to the flow of matter which passes through it (food, oxygen, heat, signals)” (Serres, Hermes 74). Just as we are related to the natural world based on flows of energy— as sunlight is converted into energy by plants, which we in turn convert into food— we are also bound together by flows of information. The task is to find new ways to sense this information, to actualise the information, and imagine nature as more than a welter of data and the air as more than background. If we think of information in broad ranging terms as “coded values of the output of a process” (Losee 254), then we see that information and the environment—as a setting that is produced by continual and energetic processes—are in constant contact. After all, humans sense information from the environment all the time; we constantly decode the coded values of environmental processes transmitted via the atmosphere. I smell a flower, I hear bird songs, and I see the red glow of a sunset. The process of the singing bird is coded as vibrations of air particles that knock against my ear drum. The flower is coded as molecules in the atmosphere enter my nose and bind to cilia. The red glow is coded as wavelengths from the sun are dispersed in the Earth’s atmosphere and arrive at my eye. Information, of course, does not actually exist as information until some observing system constructs it (Clarke, “Information” 157-159). This observing system as we see the sunset, hear the birds, or smell the flower involves the atmosphere as a medium, along with our sense organs and cognitive and non-cognitive processes. The molecules in the atmosphere exist independently of our sense of them, but they do not actualise as information until they are operationalised by the observational system. Prior to this, information can be thought of as noise circulating within the atmosphere. Heinz Von Foester, one of the key figures of cybernetics, states “The environment contains no information. The environment is as it is” (Von Foester in Clarke, “Information” 157). Information, in this model, actualises only when something in the world causes a change to the observational system, as a difference that makes a difference (Bateson 448-466). Air expelled from a bird’s lungs and out its beak causes air molecules to vibrate, introducing difference into the atmosphere, which is then picked up by my ear and registered as sound, informing me that a bird is nearby. One bird song is picked up as information amid the swirling noise of nature and a difference in the air makes a difference to the observational system. It may be useful to think of the purpose of information as to control action and that this is necessary “whenever the people concerned, controllers as well as controlled, belong to an organised social group whose collective purpose is to survive and prosper” (Scarrott 262). Information in this sense operates the organisation of groups. Using this definition rooted in cybernetics, we see that information allows groups, which are dependent on certain control structures based on the sending and receiving of messages through media, to thrive and defines the boundaries of these groups. We see this in a flock of birds, for instance, which forms based on the information that one bird garners from the movements of the other birds in proximity. Extrapolating from this, if we are to live included in an ecological system capable of survival, the transmission of information is vital. But the form of the information is also important. To communicate, for example, one entity first needs to recognise that the other is speaking and differentiate this information from the noise in the air. Following Clarke and Von Foester, an observing system needs to be operational. An art project that gives aesthetic form to environmental processes in this vein—and one that is particularly concerned with the co-agentive relation between humans and nature—is Reiko Goto and Tim Collin’s Plein Air (2010) (fig. 3), an element in their ongoing Eden 3 project. In this work a technological apparatus is wired to a tree. This apparatus, which references the box easels most famously used by the Impressionists to paint ‘en plein air’, uses sensing technology to detect the tree’s responses to the varying CO2 levels in the atmosphere. An algorithm then translates this into real time piano compositions. The tree’s biological processes are coded into the voice of a piano and sensed by listeners as aesthetic information. What is at stake in this work is a new understanding of atmospheres as a site for the exchange of information, and an attempt to resituate the interdependence of human and non-human entities within an experimental aesthetic system. As we breathe out carbon dioxide—both through our physiological process of breathing and our cultural processes of polluting—trees breath it in. By translating these biological processes into a musical form, Collins and Gotto’s work signals a movement from a process of atmospheric exchange to a digital process of sensing and coding, the output of which is then transmitted through the atmosphere as sound. It must be mentioned that within this movement from atmospheric gas to atmospheric music we are not listening to the tree alone. We are listening to a much more complex polyphony involving the components of the digital sensing technology, the tree, the gases in the atmosphere, and the biological (breathing) and cultural processes (cars, factories and coal fired power stations) that produce these gases. Figure 3: Reiko Goto and Tim Collins, Plein Air, 2010 As both Don Ihde and Steven Connor have pointed out, the air that we breathe is not neutral. It is, on the contrary, given its significance in technology, sound, and voice. Taking this further, we might understand sensing technology as conditioning the air with information. This type of air conditioning—as information alters the condition of air—occurs as technology picks up, detects, and makes sensible phenomena in the atmosphere. While communication media such as the telegraph and other electronic information distribution systems may have distanced information from nature, the sensing technology experimentally applied by EcoArtTech, Preeemptive Media, and Goto and Collins, may remind us of the materiality of air. These technologies allow us to connect to the atmosphere; they reformulate it, converting it to information, giving new form to the coded processes in nature.AcknowledgmentAll images reproduced with the kind permission of the artists.

For this thesis, smart spraying robot was designed, constructed and tested to validate the concept of smart pest control. Electrostatic charging of sprayed pesticide was realized in a spray nozzle design that improved plant coverage and reduced wasted pesticide as well as soil pollution. A thorough investigation into electrostatic spraying was conducted, which was accompanied by extensive simulations and experimentation. The results obtained from the simulation experimentation on industry standard electrostatic spray system (ESS) nozzles along with laboratory testing of these nozzles, detecting spray coverage using water sensitive paper and additional optical spray visualization methods gave the necessary insight and experience required to develop a new spray nozzle. Additional COMSOL simulation and experimentation were carried out on a Fan Hydraulic Spray Nozzle (FHSN), the results of which allowed for the effective addition of electrostatic induction capabilities, thereby transforming the (FHSN) into Electrostatic Induction Spray Nozzle (EISN) which is one of the prime parts of the smart spraying system. SOLIDWORKS software was used in the designing parts of this nozzle which were then manufactured using a 3D printer. An AL05D robotic manipulator and a TTRK tracked platform from Lynxmotion ™ were the mini mobile robot components selected for the feasibility study of the smart electrostatic crop spraying system. This mobile robot was equipped with a CCD digital camera, a range detector, and path mark detector to provide the necessary sensors required by the smart electrostatic spray system. A Windows™ based mobile computer in addition to an ARDUINO™ based orksmicrocontroller system were chosen to provide the computational power required by the system. These were arranged in a master – slave configuration, with the main processing for images and motion being conducted inside the master computer using programs created by Matlab smart ™ software. The execution of motion commands and the operation of the range and path mark detection along with operating the spray nozzle were performed on the slave computer using C as the programming language. The manufactured smart electrostatic spray system moves along cotton crop rows with a camera that scans the selected plant for pest infestation on the upper and lower surfaces of plant leaves. When a pest is detected, the spray nozzle is targeted on it at the appropriate distance, and a burst of pesticide destroys it. The results of experiments have shown that using the electrostatic induction system improves coverage 3 to 4 fold and reduces soil contamination by 2 to 4 fold. The system has plenty of room for performance improvement, and future development will make it adaptable for application to other crops and applications.

This chapter explores the complexities of working on jointly funded digital cultural heritage projects and the challenges and benefits of partnership collaborations. In the Digital Building Heritage project, researchers at De Montfort University worked with community partners in order to bring history back to life through the use of digital technologies in 3D computer animation, 3D printing, 3D modelling, and mobile geo-location. An evaluation of the researchers' experience of co-production and collaborative working highlights the importance of setting clear, feasible objectives and outcomes according to the resources available, including plans for user testing, maintaining regular communication, consideration of proposed digital product usage, and promotion. The chapter then considers the way in which this type of practice-based research can lead to academic outcomes suitable for audit programmes like the UK's Research Excellence Framework.

Notice Board is the most important thing in all schools, colleges, organization, offices and all other common public places like Mofussil Bus Terminus, Metro Station Railway Junctions and Air Ports, etc., but changing the data in the notice board daily and multiple languages are difficult process. More Manpower is required to manage notice boards. Most common issues are handling printing documents. In this paper presented novel model of smart notice board based on Internet of Things (IoT) and Wi-Fi, for multi language display. The proposed system support to minimize cost and workforce. In this system, the user can write the data from anywhere in the world to the Notice Board from an android mobile. The android application is supported by using Massachusetts Institute of Technology (MIT app) inventor. The user can send Multi language a text message or a voice message to display it in the IoT based Multilanguage smart Notice board. Whenever a new notice is updated the speaker announces an alert message “Hello everyone, a new message is displayed”. This will reduce the time to update the data as well as it will efficiently transfers the data to the notice board.

Abstract Mapping a desired 2D pattern onto a curved surface has many applications. This includes motion planning for mobile robots to perform coverage path planing, robot end effector trajectory design for tasks such as printing, depositing, wielding on a 3D surface. This problem becomes more difficult if we want the mapped pattern to keep the properties of the original pattern (i.e, least possible mapping distortion), and pass over some desired points and/or remain bounded in a specific region on the surface. In this paper, we apply surface parameterization and mapping distortion analysis, which is rarely used in robot motion planning works, to map a pattern onto 3D surface. To meet additional goals such as passing over certain points, a planar mapping determined by constrained optimization is employed on the original pattern. Our focus is on printing/depositing materials on curved surfaces, and simulations and experiments are provided to confirm the performance of the approach.

This paper presents the development of a piezo-based three-degree-of-freedom (3-DOF), tripedal microrobotic platform that allows for unlimited travel with sub-micron precision over a planar surface. Compliant mechanical amplifiers are incorporated with each piezoelectric stack actuator to improve both the stroke and load-bearing capability of the platform. A forward kinematic model of the stage based on its tripedal leg architecture is derived for each stick-slip step cycle and inverted for feedforward control of the platform. A prototype is constructed using low-cost 3D-printing techniques. Experimental results demonstrate actuator stroke of 29.4 μm on average with a dominant resonance of approximately 860 Hz. Results demonstrate the stage tracks a 3 mm by 3 mm square trajectory in open loop. Feedback control through visual servoing is then simulated on a model that includes flexure dynamics, observed surface interactions, and camera sampling times, reducing the root-mean-square (RMS) tracking error by 90%. This control scheme is then implemented experimentally, resulting in 99% RMS position error reduction relative to when only feedforward control is used.
