    In recent years, progresses in nanotechnology have established the foundations for implementing nanomachines capable of carrying out simple but significant tasks. Under this stimulus, researchers have been proposing various solutions for realizing nanoscale communications, considering both electromagnetic and biological communications. Their aim is to extend the capabilities of nanodevices, so as to enable the execution of more complex tasks by means of mutual coordination, achievable through communications. However, although most of these proposals show how devices can communicate at the nanoscales, they leave in the background specific applications of these new technologies. Thus, this paper shows an overview of the actual and potential applications that can rely on a specific class of such communications techniques, commonly referred to as molecular communications. In particular, we focus on health-related applications. This decision is due to the rapidly increasing interests of research communities and companies to minimally invasive, biocompatible, and targeted health-care solutions. Molecular communication techniques have actually the potentials of becoming the main technology for implementing advanced medical solution. Hence, in this paper we provide a taxonomy of potential applications, illustrate them in some detail, along with the existing open challenges for them to be actually deployed, and draw future perspectives

    Exploring Techno-Spirituality: Design strategies for transcendent user experiences

    This thesis presents a study of transcendent experiences (TXs) ā€” experiences of connection with something greater than oneself ā€” focusing on what they are, how artefacts support them, and how design can contribute to that support. People often find such experiences transformative, and artefacts do support them ā€” but the literature rarely addresses designing artefact support for TXs. This thesis provides a step toward filling that gap. The first phase of research involved the conduct and analysis of 24 interviews with adults of diverse spiritual perspectives, using constructivist Grounded Theory methods informed by relevant literature and by studies performed earlier in the PhD programme. Analysis found that TXs proceed in three phases ā€” creating the context, living the experience, integrating the experience ā€” and that artefacts support two phases and people desire enhancements to all three. This TX framework supports and extends experience structures from the literature: it recognises the top-level categories as phases in a cycle where integration may alter future contexts, and it extends the structure of TX by incorporating the relationships of artefacts and of enhancement desires to the phases of these experiences. This extended structure constitutes a grounded theory of transcendent user experience (TUX). The second phase involved the design and conduct of three ā€œTranscendhanceā€ game workshops for enhancing transcendence, which incorporated themes from the grounded theory and aimed to elicit design ideas in an atmosphere of imagination, fun, and play. Participants sketched 69 speculative ideas for techno-spiritual artefacts, and analysis mapped them to TX phases and identified possible extensions inspired by relevant research. The great majority of ideas mapped to the phase Creating the Context, with very few mapping to Living the Experience, which suggests that context may be easier than lived experience to understand and address directly. This point is especially important for experiences such as TX that are tricky to define, impossible to arrange or anticipate, and thus unsuitable for straight-forward ā€œclassicā€ user experience methods. The final phase involved the elaboration of workshop ideas to explore the extension of design fiction for TUX. Analysis related design fiction to the TX phases and suggested features that affect design ideasā€™ potential for TUX design fiction. This phase ended with the proposal and analysis of three new forms of design fiction ā€” extended imaginary abstracts, comparative imaginary abstracts, and design poetry ā€” using workshop ideas to illustrate the forms, their construction and use, and their benefits to TUX design. Transcendhance workshops and TUX design fictions approach techno-spiritual design peripherally, ā€œsneaking upā€ on lived experience by addressing context and enabling the consideration of ineffable experience through storytelling, metaphors, and oblique imagery. This thesis combines the grounded theory of transcendent user experience with the Transcendhance workshop process and new forms of design fiction, presenting peripheral design as a promising strategy for facilitating design to enhance transcendent experience

    Advances and Applications of DSmT for Information Fusion. Collected Works, Volume 5

    This ļ¬fth volume on Advances and Applications of DSmT for Information Fusion collects theoretical and applied contributions of researchers working in different ļ¬elds of applications and in mathematics, and is available in open-access. The collected contributions of this volume have either been published or presented after disseminating the fourth volume in 2015 in international conferences, seminars, workshops and journals, or they are new. The contributions of each part of this volume are chronologically ordered. First Part of this book presents some theoretical advances on DSmT, dealing mainly with modiļ¬ed Proportional Conļ¬‚ict Redistribution Rules (PCR) of combination with degree of intersection, coarsening techniques, interval calculus for PCR thanks to set inversion via interval analysis (SIVIA), rough set classiļ¬ers, canonical decomposition of dichotomous belief functions, fast PCR fusion, fast inter-criteria analysis with PCR, and improved PCR5 and PCR6 rules preserving the (quasi-)neutrality of (quasi-)vacuous belief assignment in the fusion of sources of evidence with their Matlab codes. Because more applications of DSmT have emerged in the past years since the apparition of the fourth book of DSmT in 2015, the second part of this volume is about selected applications of DSmT mainly in building change detection, object recognition, quality of data association in tracking, perception in robotics, risk assessment for torrent protection and multi-criteria decision-making, multi-modal image fusion, coarsening techniques, recommender system, levee characterization and assessment, human heading perception, trust assessment, robotics, biometrics, failure detection, GPS systems, inter-criteria analysis, group decision, human activity recognition, storm prediction, data association for autonomous vehicles, identiļ¬cation of maritime vessels, fusion of support vector machines (SVM), Silx-Furtif RUST code library for information fusion including PCR rules, and network for ship classiļ¬cation. Finally, the third part presents interesting contributions related to belief functions in general published or presented along the years since 2015. These contributions are related with decision-making under uncertainty, belief approximations, probability transformations, new distances between belief functions, non-classical multi-criteria decision-making problems with belief functions, generalization of Bayes theorem, image processing, data association, entropy and cross-entropy measures, fuzzy evidence numbers, negator of belief mass, human activity recognition, information fusion for breast cancer therapy, imbalanced data classiļ¬cation, and hybrid techniques mixing deep learning with belief functions as well
