From Service-Oriented Architectures to Nature-Inspired Pervasive Service Ecosystems
No full textEmerging pervasive computing scenarios require open service frameworks promoting situated adaptive behaviors and supporting diversity in services and long-term evolvability.
We argue that this naturally calls for a nature-inspired approach, in which pervasive services are modeled and deployed as autonomous individuals in an ecosystem of other services, data sources, and pervasive devices. As an evolution of standard service-oriented architectures, we present a general framework framing the concepts expressed, and discuss a number of natural
metaphors that we can adopt to concretely incarnate the proposed framework and implement pervasive service ecosystems
A survey on nature-inspired metaphors for pervasive service ecosystems
No full textEmerging pervasive computing scenarios require open service frameworks promoting situated and self-adaptive behaviors, and supporting diversity in services and long-term evolvability. This suggests adopting a nature-inspired approach, where pervasive services are modeled and deployed as autonomous individuals in an ecosystem of other services, data sources, and pervasive devices. However, there are many possibly nature-inspired metaphors that can be adopted, and choosing one may require a careful analysis of the pros and cons of the different metaphors. The purpose of this paper is to analyze the key requirements and desiderata for next generation pervasive computing services and associated infrastructures
A Biochemical Metaphor for Developing Eternally Adaptive Service Ecosystems
No full textIn the near future, pervasive sensing and actuating devices will densely populate our everyday environments, and will be tightly integrated with Telecom and Internet networks---also eventually contributing to blur their distinction
Ibrido moderno: l’istituto B. M. di Gautam Sarabhai ad Ahmedabad, India
No full textDopo le due Guerre Mondiali un approccio ha lentamente e deliberatamente rotto i legami con il passato: le smembrate colonie europee e nuove identità nazionali
hanno ibridato le diverse influenze architettoniche globalmente emerse. Questo edificio progettato da Gautam Sarabhai e costruito nel 1976 è un mirabile (e poco conosciuto internazionalmente) esempio all’interno di questa dirompente contaminazione culturale.After the two World Wars an approach has slowly and deliberately broke the ties with the past: the dismembered European colonies and new national
identities have hybridized the different architectural influences globally emerged at that time. This building designed by Gautam Sarabhai and
built in 1976 is a fine (and almost internationally unknown) example in this astonishing cultural contamination
Il recupero di una corte rurale nel veronese. Studio wok architetti associati [The renovation of a rural court in the Verona area]
No full textUna nuova abitazione ricavata in una parte del fienile di una corte agricola alle porte di Verona, vicino al fiume Adige, apre un “dialogo tra storia e contemporaneità: un dialogo spaziale e materico in una corte rurale” così come dichiarato dai progettisti, lo studio wok di Marcello Bondavalli, Nicola Brenna e Carlo Alberto Tagliabue
A biochemical approach to adaptive service ecosystems
No full textEmerging network scenarios call for innovative open service frameworks to ensure capability of self-adaptability and long-lasting evolvability. In this paper, we assess the need for such innovative service frameworks, and discuss how their engineering should get inspiration from natural ecosystems, i.e., by modelling services as autonomous individuals in an ecosystem of other services and data sources. We introduce a reference conceptual architecture with the goal of clarifying the concepts expressed and framing the several possible nature-inspired metaphors that could be adopted to realise the idea. On this basis, we go into details about one of such possible approaches, in which the rules governing the ecosystem are inspired by biochemical mechanisms. A case study is also introduced to exemplify the potentials of the presented biochemical approach and to experiment with some representative biochemistry-inspired patterns of adaptive service organisation and evolution

Spatial coordination of pervasive systems through chemical-inspired tuple spaces
No full textPervasive computing calls for developing distributed infrastructures featuring large-scale distribution, opennes, context-awareness, self-organisation and self-adaptation. There, it is quite natural to see services (software functionality, data, knowledge, signals) as spatial concepts: they are naturally diffused in the network, and in each location they are sensitive to the context and compete with each other - as such, they can be active in one or multiple regions (niches) of the network. To support and engineer this scenario, we propose a nature-inspired coordination model of chemical-inspired tuple spaces. They extend standard tuple spaces with the ability of evolving the "weight" of a tuple just as it represented the concentration of a chemical substance in a biochemical system, namely, in terms of reaction and diffusion rules that adaptively apply to tuples modulo semantic match. We show that this model can be used to enact self-* properties in pervasive systems, through typical spatial patterns involving computational fields, paths, and segregation. © 2010 IEEE
Does Tourism Consumption Behaviour Mirror Differences in Living Standards?
No full textBased on the theoretical foundation of well-being measurement, the study explores differences in living standards by analysing the distribution of tourism expenditure. A mixture of regression models is used to explore the heterogeneity in tourism consumption by identifying groups of families with similar tourism consumption behaviour as a function of certain socio-demographic and economic factors. The empirical analysis, performed on Italian expenditure data, suggests that there are three different patterns of consumption behaviour conditional to the socio-demographic and economic covariates in the tourism market and that differences in tourism consumption between groups of households mirror inequalities in living standard
Representing the imagination. Reflections on the playful reinterpretation of objects of the twentieth century design
No full textThe well-known chairs designed by Gerrit Rietveld at the beginning of the XX century, the Berlin and Red Blue Chairs, were part of an academic investigation within the framework of an Industrial design bachelor course. In order to better involve the young students of the first year, a gaming experience has been conceived by means of thoughtful activities (documentation / design) and shape analyses. The methodology had the effect of spurring the students to develop a drastic transformation of the chair: the objects become components able to activate new design skills by imagination and creativeness
