L’Axe de recherche « Nouveaux Matériaux, Systèmes Intelligents et Entreprises innovantes » organise ses travaux autour de quatre sous-axes de recherche majeurs :
La recherche de matériaux intelligents fonctionnels représente un défi majeur dans de nombreux domaines tels que l’automobile, l’aéronautique et la biomédecine. Dans ce contexte, nos chercheurs collaborent en mettant en commun leur expertise pour concevoir des métamatériaux bio-inspirés architecturés et des smart matériaux, depuis la phase de conception numérique jusqu’à l’optimisation des propriétés structurales et/ou fonctionnelles, en passant par la fabrication et la caractérisation expérimentale. Les technologies développées réunissent des compétences dans plusieurs domaines, notamment la modélisation et simulation numérique multi-échelles, la simulation par éléments finis, l’Intelligence Artificielle, l’impression additive, le smart manufacturing et les méthodes expérimentales.
Dans le cadre de la transformation numérique, la sécurité digitale joue un rôle primordial. Au sein de l’Axe ce thème englobe la cybersécurité, la sécurité des réseaux, la résilience et la cryptographie, revêtant une importance significative avec une visibilité à la fois nationale et internationale. Le deuxième thème porte sur les systèmes intelligents, qui sont des composantes essentielles de la transformation numérique. La recherche au sein de l’Axe dans ce domaine se concentre sur les interactions entre l’humain et la machine, que ce soit du point de vue visuel, audio et/ou tactile, ainsi que sur la robotique, les objets connectés, l’IoT, la réalité virtuelle, et la e-santé, en lien avec les récentes avancées de l’intelligence artificielle.
La manière d’organiser l’innovation et l’impact des innovations sur nos vies sociales, comportementales et organisationnelles revêtent une importance cruciale tant sur le plan théorique que pratique. Nos membres excellent à l’échelle internationale dans la compréhension et l’exploration du développement de nouveaux produits et processus, ainsi que dans d’autres domaines tels que la gestion des innovations technologiques, l’encouragement du talent, l’optimisation de la chaîne d’approvisionnement, la gestion avancée des entrepôts et des opérations, la promotion de marques, et l’impact qu’ils apportent aux individus, aux groupes et aux pays grâce à ces innovations. Nous avons également acquis une expertise dans le financement, le recrutement et le développement d’entreprises innovantes (entrepreneuriat et création de nouvelles entreprises).
Nous sommes très intéressés par la recherche de stratégies qui favorisent, promeuvent et gèrent les innovations dans ce monde numérisé et hyper-connecté. Nos membres se consacrent à l’étude de la stratégie numérique et de la transformation numérique, les ethnographies des phénomènes numériques (par exemple, la ludification, la blockchain, la gestion algorithmique), la psychologie dans un contexte numérique (affects et émotions dans l’espace numérique), le marketing numérique, les interactions numériques et sociales (via les dispositifs portables, la robotique, l’apprentissage profond, les jeux, etc.), ainsi que par l’analyse des modèles économiques existants et de l’évolution des entreprises innovantes.
Parmi les projets interdisciplinaires, nous incluons :

Purpose
The present study attempts to analyze how social entrepreneurs (SEs) develop technological innovation in the face of diverse institutional logics, which are embedded in the National Systems of Innovation (NSI).
Design/methodology/approach
Based on the content analysis of Ashoka Fellows, the study compares SEs in developed and developing countries, which represent strong versus weak NSIs.
Findings
SEs selectively couple the elements of diverse institutional logics to ensure the resource inflow and legitimacy of their operations. However, SEs particularly at weak NSIs are also decoupling their profit and non-for-profit branches to address conflict among diverse logics. Moreover, the study finds that 12 out of 20 entrepreneurs who identify themselves as technologically innovative did not develop any new technological innovation.
Practical implications
The study shows that being technologically innovative depends on the acquisition of resources and the management of legitimacy challenges, SEs can diversify their innovations by creating more incremental, architectural and modular innovations to address competing demands among logics.
Social implications
The study reveals that SEs in weak NSIs interact with multiple institutional logics more frequently than their counterparts in strong NSIs. Although this context leads them to diversify their technological innovation, there is a need for improving the NSIs of SEs in developing countries to facilitate the continuity of resource inflow and ensure the legitimacy of their operations.
Originality/value
Integrating two complementary theoretical lenses, the study contributes to the literature by exploring the impact of the interaction between logics nested within a supra system and SEs' ability to develop technological innovation.},

This article looks at how an incumbent firm approached such constraints, and used cognitive artifacts to transform its value chain into a collaborative ecosystem. It examines the case of a 3D printing-enabled shift to mass customization of orthopedic medical implants. The results demonstrate how firms can use artifacts to build a shared understanding across heterogeneous stakeholders as they explore and develop new open innovation models, and how this process can be managed flexibly to avoid adopting a locally (rather than globally) optimal strategy.},

Enterprises are becoming more agile, adaptive, and ambidextrous in order to boost innovation in the current digital transformation era. Nowadays, ?digital innovation' is closely associated with Industry 4.0 enablers and smart enterprises. Prior research has shown that while multinational enterprises ? across many sectors ? have already embraced the afore?mentioned advancements, their adoption by small?and?medium?sized enterprises (SMEs) has so far taken place mainly in the manufacturing sector. Thus, based on a sample of 280 self?tuned smart manufacturing SMEs and having utilized the structural equation modelling (SEM), this study was aimed to investigate how digital innovation is influenced by the three pillars of self?tuning models ? agility, adaptation, and ambidexterity. Our article has focussed on the digital systems in which SMEs, spurred by networking and open innovation solutions, operate and innovate in response to external triggers, displaying a balance between exploration and exploitation, and a strong agile capacity.},

abstract = {The aim of this contribution is to improve the behavior and failure prediction accuracy for magnesium alloy sheet forming simulation by using advanced fully coupled Continuum Damage Mechanics (CDM) model. Starting from known fully coupled constitutive equations at large inelastic (plastic or viscoplastic) strains, three aspects are enhanced on the CDM model developed by Saanouni (2012). The first one concerns the accurate description of tension-compression asymmetry in yielding and hardening of magnesium alloys induced by combined slip and twinning deformations. The second concerns introducing the stress state dependence in damage evolution to improve the fracture prediction under various loading paths. The third deals with temperature and strain rate (viscosity) effects for metal forming processes at elevated temperatures. The improved fully coupled constitutive equations were implemented into finite element code ABAQUS/Explicit via user subroutine VUMAT including the specific local integration scheme to compute the state variables at each quadrature point. Various kinds of tensile tests at different temperatures and strain rates are used to determine the material parameters, and the complete identification procedure is given in details. As validation, the improved model is applied to simulate the three-point bending and circular cup deep drawing tests, the predicted results show good agreements with the experimental observations.},

We specifically argue that venture capital is an important complementary resource in the entrepreneurial process, providing entrepreneurs with access to critical financial assets as well as contributing to the development of local, regional, and national entrepreneurial networks. Accordingly, we expect venture capital flows to be higher in counties with underdeveloped entrepreneurial ecosystems, providing venture capitalists an opportunity to better leverage their financial and human resources, thus enhancing return prospects on the invested capital while contributing to the development and functioning of entrepreneurial ecosystems.},

It unpacks somametamnemata, a technologically mediated practice of self care, consisting of three entangled aspects: caring about self through practicing bodywork online; caring about self and others through sharing about the bodywork in the comments; and caring about self and others through responding to shared verbalizations of bodywork, and distinguishes it from known practices of self-care, thus contributing to the literature on technologies of self. Through indicating the well-being potential held within ill-being, it contributes to overcoming dichotomy between the negative views of ill-being and positive views of well-being, and revisits a debate on ?corporate wellness? by highlighting that employees' well-being may necessitate ?third places? outside organizations.},

Ainsi, les industriels de la CFAO dentaire fournissent des packages FAO-MOCN pré-intégrés où les stratégies d'usinage, les outils d'abrasion et les cinématiques machine sont imposés. Les biomatériaux à mettre en forme dans le cadre de la réalisation de prothèses dentaires couvrent de nombreuses familles allant des polymères, des composites aux céramiques selon le cas clinique à traiter. Pourtant les stratégies d'usinage, les outils et les conditions de coupe proposés diffèrent très peu d'un matériau à l'autre. D'un point de vue clinique, les praticiens observent de grandes variations sur l'intégrité de surface des prothèses réalisées notamment en terme de rugosité ou encore d'écaillage de bords fins. La rugosité est un critère important influençant les propriétés de collage, esthétiques ou encore de développement de la plaque bactérienne. L'écaillage souvent constaté en limite marginale, zone assurant l'étanchéité entre la prothèse et les tissus dentaires à restaurer et à préserver, pose quant à lui des problèmes de tenue mécanique ou de reprise de pathologie carieuse. Les résultats expérimentaux ont permis de dégager des premières pistes d'amélioration des stratégies d'usinage à mettre en oeuvre pour les prothèses dentaires.},

abstract = {Corporate social responsibility (CSR) has been one of the most dynamic concepts of business literature. It evolves over time and significantly varies across contexts. The joint effect of these two dimensions requires analyzing the notion of social responsibility more frequently than most concepts. The current study attempts to contribute to the literature by focusing on the current practices of CSR in Turkey. In addition to the large-scale effect of global industrial trends and technological advancements, Turkey has also experienced a highly complex political, economic, and social transition during the 2000s. Considering the impact of dynamic and competing institutional logics, the study tries to provide a deeper understanding on how CSR perception and practices have evolved in Turkish business context to date. The study reveals that philanthropic component of CSR has been strengthened as a phenomenon in the nexus of family, religion, community, and market logics. Whereas, the ethical and environmental components are not fully integrated into the CSR agenda of Turkish business organizations. CSR has been also polarized during the 2000s in line with the overall political climate of country. Under the politics of government party, which has been in the office since 2002, business organizations are highly cautious on which issues they should address or whom they should work with.},

This mechanism is proposed to be incorporated as an articulation unit for a piping inspection robot in order to overcome pipe bends and junctions. In the event of a junction, external actuations are required to allow the mechanism as well as the robot to follow a certain direction. Using DC-motors coupled with encoders, experiments are carried out on a test bench of the tensegrity mechanism. The actuation of the mobile platform is performed using cables that pass through each spring. By correlating the architecture to a 3-SPS-U parallel mechanism, the singularity-free workspace of the mechanism is analyzed to identify the tilt limits. A closed-loop PID controller is implemented using a microcomputer to perform a linear trajectory within the singularity-free workspace. The Inverse Kinematic Problem (IKP) is solved by passing input tilt angles to the controller. With the help of a force control algorithm, the experiments are carried out under no-load conditions for vertical and horizontal orientations of the mechanism. The error data of the joint positions and the motor torques are then interpreted for both orientations of the mechanism.},

We consider the equilibrium decision between the green level and the retail price to maximize the supply chain's profit. Furthermore, we conduct experiments to verify our analysis results. Interestingly, this study finds that it is optimal for the retailer in the decentralized case to charge a higher price when the green sensitivity increases. However, the optimal price in the centralized case is not necessarily monotonic when the demand is lower. The manufacturer should set a higher green level as the greening investment parameter increases.},

abstract = {Physical Human-Robot-Interaction (pHRI) is beneficial for communication in social interaction or to perform collaborative tasks but is also crucial for safety. While robotic devices embed sensors for this sole purpose, their design often is the results of a trade-off between technical capabilities and rarely considers human factors. We propose a novel approach to design and fabricate compliant Human-like artificial skin sensors for robots, with similar mechanical properties as human skin and capable of precisely detecting touch. Our artificial skin relies on the use of different silicone elastomers to replicate the human skin layers and comprises an embedded electrode matrix to perform mutual capacitance sensing. We present the sensor and describe its fabrication process which is scalable, low-cost and ensures flexibility, compliance and robustness. We introduce Muca, an open-source sensing development board and then evaluate the performance of the sensor.},

abstract = {Small to medium enterprises (SMEs) are often marked by limited resources, a high dependence on others, and a scope of business that gets narrower as they seek to adapt to the current dynamic and knowledge-intensive context. Additionally, in their relationship with multinational enterprises (MNEs), SMEs are driven to a continuous specialization of their knowledge and technological resource bases. They so source global knowledge by positioning along a global value chain of those MNES. Especially SMEs employ a repositioning organizational knowledge dynamics by functional upgrading and downgrading strategy. In order to address the query on dynamic capabilities in knowledge management (KM) in different inter-organizational collaborations in the global value chain, this study shows that the choice between functional upgrading or downgrading can determine a more effective cross-innovation strategy which enables SMEs to exploit external paths to the market by revealing or selling their ideas, knowledge and technologies. Such strategies can reveal opportunities for SMEs to increase their network to find an optimum position in the market. SMEs, in turn, become more specialised in their offerings, moving up or down the global value chain, leveraging on a combination of dynamic and technological capabilities along with high degree of involvement in knowledge management process},

abstract = {By shifting towards Romer's (Am Econ Rev 94:1002-1037, 1986) economy and so the spread of knowledge economy, universities started to adopt a collaborative approach with their entrepreneurial ecosystem. They turn out to be risk taker, autonomous, proactive, competitive, and innovative. In a nutshell, they are entrepreneurial oriented with the aim to generate new innovative ventures, known as research-based spin offs. Doubly, this has induced an improvement of technology transfer and the degree of entrepreneurship in the current knowledge economy. However there still is a paucity of studies on the spill over effect of entrepreneurial orientated universities and research-based spin off on technology transfer need to be more explored. Therefore, the article investigates the link between entrepreneurial orientation and such spill overs by offering an outlook of two universities and two research-based spin offs in the United Kingdom. The scope is to provide a deep view of technological innovativeness in a research context, entrepreneurial oriented. Our research suggests that entrepreneurial attitude has become an imperative to succeed in the context where British institutions currently operate. Entrepreneurship brings the necessary technological innovation to the university and its students, which results in better positioning of the university at national and international levels, with the subsequent impact on their ability to attract not only new students and academics but also funding to conduct their research.},

By studying 80 SMEs from the high-tech manufacturing sector in Italy, this research has found that, when combined with stakeholder engagement, sustainable innovation management becomes a pivotal phenomenon for new and established SMEs. Stakeholders proved instrumental in generating the sense of environmental responsibility in SMEs. As a pioneer combination of stakeholder theory and innovation management theory, our research found that stakeholder-related capabilities, both tangible and intangible, influence the firm's orientation towards sustainable innovation, its environmental responsibility and related capabilities. Our research assists the sustainability, adaptation, innovation and growth orientation of SMEs in a knowledge-intensive environment by recommending that, in their relationship with stakeholders, SMEs become more open to co-create, share and reuse environmental knowledge.},

It takes into account three different criteria to select the best relay to send data: (1) the contact duration between vehicles, (2) the available load of each vehicle, (3) and the log of encountered communication errors embedded in each cluster head. The multi-criteria strategy allows the selection of the most reliable vehicles by avoiding communication problems and ensuring connection availability. Once the hybrid control plane has found out the next eligible neighbor, the data plane will be in charge of dividing and sending data. To validate our approach, HSDN-GRA has been modeled and implemented in JADE, a multi-agent platform, to be compared to other multi-agent based protocols. Simulation results show that HSDN-GRA achieves good performance with respect to the average routing overhead, the packet drop rate, and the throughput.},

The proposed constitutive equations are implemented into Finite Element (FE) code ABAQUS/Explicit through a user material subroutine (VUMAT). The material parameters are determined by the hybrid experimental-numerical method using various tensile and shear tests. Validation of the proposed model has been done using different tests of two aluminum alloys (Al6061-T6 and Al6014-T4). Through comparisons of numerical simulations with experimental results for different loading paths, the predictive capabilities of the proposed model have been shown. The model is found to be able to capture the initiation as well as propagation of macro-crack in sheet and bulk metals during their forming processes},

Purpose
The purpose of this study is to propose a definition and model of social sustainability within the ambit of systems theory and to test it on hospitality e-distributors. The study suggests that social sustainability arises through the congruence among the interrelated components of social innovation, societal demand and social stakeholders in a transformation model and it can be assessed to whether and how this congruence addresses to the equity principles.
Design/methodology/approach
The study provides a case analysis on two selected hospitality e-distributors - Booking.com and Airbnb. The data obtained from a video-based content on managerial interviews were triangulated with the data of corporate disclosures and expert views derived from a focus group study.
Findings
The study reveals that both companies affect the intra-generational, procedural and geographical equity principles across physical and virtual communities so long as they take the advantage of their strategic positions. While Booking.com transforms its own industry, Airbnb disrupts the entire system by blurring the boundaries between market and non-market as well as touristic and non-touristic areas.
Practical implications
The study contributes to the practitioners by showing how to configure and assess the social sustainability of their organizations at the different contexts.
Social implications
The study provides a holistic perspective on social sustainability by linking the concept with social innovation, societal demand and social stakeholders and highlighting its contribution to equity principles.
Originality/value
Despite the proliferation of studies, the authors have very little understanding on the social pillar of sustainability. The current study fills the gap by addressing these conceptualization and measurement challenges in the literature.},

abstract = {A variant of the program iteration method called stability iterations is used for a differential game of pursuit-evasion. The successful solvability set of one of the problems generating the game is found as a limit of the iterative procedure in the space of sets whose elements are positions of the game. The game is defined by a pair of closed sets, one of the which is the target set in the pursuit problem (the first player's problem) and the other specifies the state constraints in this problem. For the positions not belonging to the solvability set of the pursuit problem, it is interesting to determine the smallest "size" of a neighborhood of the two mentioned sets for which the first player can implement the guidance to the neighborhood of the target set corresponding to this "size" within the similar neighborhood of the second set, i.e., the set specifying the state constraints. Similar constructions are considered for the sets realized at each stage of the iterative procedure. We use the connection of these constructions with the mentioned smallest "size" of neighborhoods of the sets that are parameters of the differential game in the sense of guaranteed realizability of guidance under the replacement of the original sets by these neighborhoods.},

Guaranteeing organizational efficiency and 2. Exploiting effectively market opportunity. This usually implies the integration of knowledge in technology transfer which can be accrued via the knowledge sharing between parties. However, by looking into the technological and social change literature, previous studies were mainly focused on macro-foundation of technology transfer and organizational innovative capabilities with less consideration to the role of psychological precursors of collaborations. Due to this gap, we intended to build a consistent conceptual basis for collaborations and technology transfer practices at the micro level. Therefore, drawing on the theory of planned behaviour (TPB) we propose a micro-foundation model for collaborative innovation and technology transfer.},

abstract = {Systems are getting increasingly complex and challenging to design. For safety-critical systems, the integration between model-based systems engineering and model-based safety assessment to improve the choice of the system architecture since the early design stage becomes a necessity. One of the integration solutions is to generate fault trees (FTs), either static or dynamic, directly from the system description. In this paper, we are particularly interested in the generation of the dynamic fault trees (DFTs) of the systems that contain redundancies, which is widely used in safety-critical systems to enhance their reliability. The goal of this paper is, first, to propose a redundancy profile and, second, to automatically generate the DFTs from system models. Since errors are propagated via input and output ports of the components, the generation process starts with a depth-first search graph traversal through the systems modeling language internal block diagram of the system. This diagram is considered as a multidirected graph in order to detect the external inputs, the nonredundant components, the switch components, and the redundant components of the system. Then, the redundancy information incorporated in the system model is used to generate the appropriate combinations of the FT. This FT is represented in a suitable format that can be studied using FT analysis tools, for both qualitative and quantitative safety analyses.},

abstract = {Dental prostheses are machined by computer-aided design and manufacturing (CAD/CAM) tools. The integrity of the surface obtained, which must be suitable to meet expected clinical requirements is influenced by the milling parameters programmed. The integrity of the occlusal prosthesis surface obtained by the end milling mode, that is milling with a diamond rotary cutting tip, plays a major role in the clinical requirements desired. This study aims to investigate the impact of the tool-biomaterial couple in the CAD/CAM end milling mode on surface integrity (through roughness). Two CAD/CAM tools and four CAD/CAM biomaterials, both combined to four feed rates are tested. The surface roughness (Ra, Rt, Rz, Sa, Sq, and Sz) is observed for each couple. Finally, pairwise comparisons (Kruskal-Wallis test) of tool-biomaterial couples are performed. The results indicate that all the machined surfaces reveal isotropic surface topology. The roughness depends on the hardness of the biomaterial and not on the feed rate. The statistical tests reveal a significant difference in roughness depending on the tool used. To conclude, when milling the functional occlusal shape, biomaterial hardness and the tool used are key factors for achieving a given roughness consistent with clinical requirements.},

In this work, we investigate its adaptation in the quantum world, when an adversary can perform superposition queries. The security of quantum-secure classical encryption has first been studied by Boneh and Zhandry (CRYPTO'13), but they restricted the adversary to classical challenge queries, which makes the indistinguishability only hold for classical messages (IND-qCCA2). We extend their work by giving the first security notions for fully quantum indistinguishability under quantum adaptive chosen-ciphertext attacks, where the indistinguishability holds for superposition of plaintexts (qIND-qCCA2).},

Using a life history approach, we illustrate how Maria - a part-time yoga teacher and single mum of two - navigates acute experiences of embodiment (ill health, childbearing and childrearing) and the economic precarity of supporting herself and her family. We theorize how the mobilization of spirituality through doing and teaching yoga represents a reprieve and health-management tool, but also produces and reinforces neoliberal, postmaternal and postfeminist discourses. This ultimately results in the individualization of responsibility in terms of work, but also personal health and family demands.},

These two architectures are correlated to 3-SPS-U and 4-SPS-U parallel mechanisms for determining their geometric equations. By fixing the limits of prismatic joints, the workspace for the mechanisms is generated and the parallel singularities are analyzed. Based on the singularity boundaries obtained from the workspace, the joint limits are modified to generate the maximal singularity free workspaces for both the architectures. A comparison is done based on the tilt limits obtained from the workspace of the mechanisms. The mechanism with the maximum tilt limits is implemented for a piping inspection robot to pass through pipe bends and junctions.},

abstract = {This article presents an optimization approach for the design of an inspection robot that can move inside variable diameter pipelines having bends and junctions. The inspection robot uses a mechanical design that mimics the locomotion of a caterpillar. The existing prototype developed at LS2N, France is a rigid model that makes it feasible for working only inside straight pipelines. By the addition of a tensegrity mechanism between motor units, the robot is made reconfigurable. However, the motor units used in the prototype are oversized to pass through pipe bends or junctions. An optimization approach is employed to determine the dimensions of motors and their associated leg mechanisms that can overcome such bends. Two optimization problems are defined and solved in this article. The first problem deals with the determination of motor sizing without leg mechanisms. The second problem deals with the determination of sizing of the leg mechanism with respect to the dimensions of motor units obtained from the first problem. A 3D model of the optimized robot design is then realized using CAD software.},

abstract = {Today's systems involve increasing functionality and different engineering domains, and thus are getting more complex. To deal with this complexity while designing safety-critical systems, it is required to integrate systems engineering and safety assessment to support functional and dysfunctional behaviors as early as possible. The use of models is also compulsory for the design of complex systems to perform simulations and evaluate several alternatives with regard to various requirements and constraints. In this paper, we propose to explore the feasibility of a model transformation to automatically generate safety analysis models with AltaRica 3.0 from system models with SysML. The meta-models linking the two languages that share some similar concepts to model system architecture and behavior are used to generate classes, blocks, events, transitions and assertions in AltaRica. Starting from the same system specification, the automatically generated safety code from systems engineering models can be compared to code written manually by safety engineers to verify if they are semantically equivalent. This transformation provides systems engineers and safety experts with means to collaborate, reduces error-proneness and inconsistencies, and ensures that safety experts perform safety assessment on up-to-date system models.},
