abstract = {As the population ages in modern societies and the risks of bone diseases or bone accidents increase, there is a need for a new generation of materials with superior biocompatibility and good mechanical properties. This study combines two innovative metallurgical concepts to provide a material solution for the intended application. To this end, multicomponent and complex concentrated alloy (HEA/CCAs) based on TiNbZr-X (X = Mo, Ta) system is fabricated via additive manufacturing (AM), namely by Laser-Powder Bed Fusion (L-PBF) of gas-atomized pre-alloyed powder. After each stage of development by L-PBF through Taguchi's design of experiments, complete microstructure characterization and mechanical behavior of the resulting samples under different loading conditions are conducted. In addition, mechanical surface functionalization carried out by machining with metrological monitoring as a pre-step before a chemical functionalization for the suitability of materials developed for the intended application.},

the development of complex geometric shapes with a beneficial mass to robustness ratio. However,

designing and fabricating with this matter is complex, and the existing design primitives for shape

change can constrain designers' creativity. We present a pipeline that allows users and designers to

explore and compose with various shape-change primitives. To this extent, we rely on digital simulation

combined with a simple digital fabrication tool. This pipeline allows to explore and visualize deformation

and develop new application cases for shape-changing interfaces. We propose a workshop around

manipulating these tools to foster discussion between designers and researchers around the future of

shape-changing interface fabrication},

abstract = {Les robots d'inspection de canalisations jouent un rôle important dans des industries telles que le nucléaire, la chimie et les eaux usées. Ils peuvent opérer avec précision dans un environnement irradié ou pollué, réduisant ainsi les risques pour les humains. Ce travail commence par l'étude du cas d'un robot d'inspection bio-inspiré rigide qui a été développé au LS2N, France pour AREVA. Des modèles statiques et dynamiques sont développés pour comprendre les forces de serrage et les couples des actionneurs du robot. Des validations expérimentales sont également effectuées sur le prototype pour interpréter les forces d'actionnement en temps réel. Pour améliorer sa mobilité, l'architecture du robot est rendue flexible par l'ajout d'un mécanisme de tenségrité. Deux types de mécanismes de tenségrité sont proposés et analysés avec des méthodes algébriques pour comprendre leurs limites d'inclinaison et pour connaître l'influence des paramètres de conception. Des expériences sont réalisées sur l'un des prototypes des mécanismes de tenségrité développés au LS2N avec deux types de trajectoire en positions horizontale et verticale. Ensuite, une optimisation est réalisée pour identifier les moteurs qui peuvent permettre du robot d'inspection de canalisation flexible de passer les coudes et les jonctions pour une plage donnée de diamètres de tuyaux. Une maquette numérique du robot flexible est réalisée dans un logiciel de CAO.},

abstract = {Cyber-Physical Systems (CPSs) are intensively used in many different kinds of industrial

systems. Whether you are driving a recent car, taking the plane, having a smartphone or smart watch, you interact with CPSs. If we sometimes feel more comfortable or secure with them, these systems are very exposed to cyber-attacks. This is due to their highly interconnected nature and implies that they need to be carefully protected. Thus, one of their main challenges is to ensure their security.

Recent years have seen an increasing concern about the cybersecurity of CPSs and many methods have been developed to answer their challenges.



In this article, we focus on a recent philosophy of doing cybersecurity, inspired by Model

Based System Engineering (MBSE), called Model Based Security (MBS) or Model Driven Security [1]. This specialization of MBSE has been first applied to IT systems and is now a growing research field for CPSs as it helps to automatize cybersecurity assessments that are quickly intractable for engineers working on complex systems.



Despite the growing interest regarding MBS for CPSs, this method is poorly applied in

industry. Most of the works have been made in research labs and have not yet reached industrial application level. Furthermore, these works are relatively diverse and focus on different fields or different aspects of security. This variety is a chance and a problem because there is no consensus in the community on how to apply MBS to CPSs. Indeed, there is no established formal way to define systems (especially the interactions between the physical and cyber layer), threat models, scenarios of

attacks (qualitative analysis), potentiality evaluation (quantitative analysis), deployment phases, etc. [1] [2]. In addition, the abstraction is too high level to describe the complex interactions involved in CPSs or too low level to handle complexity [3].



The major contribution of this work is thus to summarize the actual strengths and weaknesses

of MBS for CPS. To do so, we propose to dig into some recent works and analyze them to understand the needs and missing theoretical background in this field. Then, with a clear overview of the issues about MBS, we will identify some solutions or trigger points that might help to make this type of

approach more attractive and exhaustive.

Finally, it will be possible to introduce an approach allowing MBS for CPS with the concern to cover some challenges of MBS for CPS with a simplistic, yet comprehensive, formalism.},

organization = {ESSEC Business School},

abstract = {While the workplace literature has discussed playfulness as the nature of work as well as the designing of work, there is only limited research that focuses on how designers identify and disidentify with games over time. A Lacanian enquiry into the self-identification of serious game designers may prove particularly worthwhile, as designers first need to cope with their own fantasmatic attachment if they are to develop serious games that seduce others. A brief case study investigates this issue through the ethnographic observation of how lack, identification and fantasy are all dynamically intertwined in the context of the development of a serious medical game aimed at the elderly. The findings describe the process through which designers confront their gamified scenario, and how they overcome the resulting tension. The discussion reveals the traumatic origin of their playful fantasy, namely the affective underside of suffering and conflict. However, ethical designers resist, and eventually undo, gamification through ambivalent acting and ?crossing? the fantasy. Finally, the conclusion presents broader implications for serious game design and future avenues for empirical research in the Lacanian tradition.},

Indeed, diverse architectures and models have been proposed for smart grids. In this paper, we propose a model composed of two parts, the first part is to optimize, on a weekly scale, thermal generation, and energy storage while prioritizing renewable energy sources to minimize global costs and global warming effects. The second part consists of, having optimized production and storage, the negotiation between neighboring holons on the same level using evolutionary game theory, combined with simulated annealing and Q-learning approaches to ensure a back and forth between the various levels.},

booktitle = {11th European Solid Mechanics Conference},

abstract = {Material's resistance-to-failure is quantified by two dependent material constants (one is proportional to the square of the other): fracture energy and fracture toughness. Predicting their values from the solid structure at the atomistic scale remains insolved, even in the simplest situation of an ideal brittle fracture. By examining numerically crack growth in electrical analogues of brittle crystals with modulated geometries, we shed a new light on this question. We find that the value of fracture energy cannot be deduced from Griffith's free surface energy, as is generally believed [1]. Rather, it finds its origin in the matching between the continuum-level scale displacement field of solid mechanics and the discrete nature of solids at the atomic scale. By making use of the generic asymptotic form, referred to as Williams's series expansion [2], taken by the displacement field near the crack tip, we find an analytical solution for this matching, and subsequently a way to predict quantitativly fracture toughness from the atomistic parameters [3]. We will discuss how to extend the analysis to genuine elastic (plane stress) crack problems and predict fracture toughness in 2D and 3D materials. This work sheds new perspectives on how resistance-to-faillure is selected; and hence, how it can be improved. As such, it may catalyze novel research toward new architectured materials of superior strcutural performance via microstructure patterning : tougher, more durable, lighter and/or combining other functionalities.},

We empirically ground the notion of digital ritual infrastructure through a study of WellTech, an association of digital start-up organizations whose focus is designing wellbeing-related workplace technologies. To understand how digital rituals are shaped by these technologies, we draw upon interviews, archival and observational data. Our findings suggest that digital ritual infrastructure supports but also rescales and revalues rituals. In this process, technology-mediated ritualized action is directed towards designed function, potentially foreclosing on opportunities for socially creative or unexpected effects. We discuss the implications of our findings for understanding ritual in digitalized workplaces.},

Paper scores are overlaid onto a staff drawn with conductive ink and connected to an Adafruit musical box. Pressing a note in the score triggers its sound, and running fingers over the notes plays a melody.

Learning to read music from the score is an essential part of Western classical music training. Traditionally, children learn the different music notes by singing or playing notes on an instrument, guided by a teacher. We envision a way for children to learn the correspondence between notation and sound by directly touching the score.

The Interactive Score is effortless to use and allows children to make discoveries on their own. The correspondence between the visual, the tactile , and the sound can aid in learning.},

We then apply these concepts in a short empirical vignette, in which affect plays a central role in explaining why some technologies ?make it?, whilst others do not. We conclude by discussing ontological, epistemological and practical opportunities for further research.},

Based on a thematic analysis of 7,234 comments posted on the Yoga with Adriene YouTube channel in 2020, this study unpacks a technologically mediated practice of self-care, which we conceptualize as somametamnemata. Our findings illustrate three entangled aspects of somametamnemata relating to yoga, a form of bodywork: Caring about self through practicing yoga online; caring about self and others through sharing about yoga in written comments; and caring about self and others through responding to shared verbalizations of yoga. This study distinguishes somametamnemata from known practices of self-care, advancing existing literature on technologies of self by overcoming the dichotomy between negative views of ill-being and positive views of wellbeing. By situating the potentiality of individual wellbeing within ill-being, we shift debates and discussions of ?corporate wellness? beyond organizational boundaries.},

abstract = {Soft Robotics rapidly emerged as an area of interest in Human-Computer Interaction (HCI). Simple DIY fabrication processes and platforms were re-adapted from traditional digital fabrication tools, resulting in making soft materials-based prototyping accessible to the design and maker community. 

There is a growing interest in the use of bio-based and bio-degradable materials in design and prototyping, creating discussions around sustainable design practices as new motor of interdisciplinary exchange. These materials are abundant in Nature, have properties extensively explored in bio-engineering, and are potent in driving sustainability.

However, soft robotics and shape-changing interfaces are not yet developed using these new materials alternatives. 

In this context, we highlight potential materials and advocate for their democratized use in soft robotics and HCI. More precisely, we propose an empiric overview of the main challenges in prototyping with bio-based and/or bio-degradable materials, pointing therefore how fabrication processes and tools need to be adjusted once again.},
