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.

abstract = {Mobile augmented reality (MAR) has gained significant attention in the tourism sector as a way to enhance the visitor experience. The rapid advancements in mobile computing and sensor technologies have facilitated the widespread use of geospatial augmented reality (AR) applications by tourists when exploring popular destinations. To analyze the impact of AR technology on the tourism experience, we developed the FEZAR mobile application. This application serves as the focal point of our study, allowing us to evaluate user performance using a comparative experimental approach. To ensure the usability of the FEZAR application, professionals with expertise in mobile technologies, including AR, performed rigorous testing and evaluation of the application. Through their evaluations, significant usability issues were identified and resolved, resulting in the application being well-received by the experts. Subsequently, a comparative field study was conducted in Fez's old medina, a crowded UNESCO heritage site, involving users (N = 40) who were randomly assigned to experimental and control groups in equal distribution. The results of the study revealed that the proposed AR model had a significant positive impact on user visits. Compared to other forms of media, AR offers more informative and enjoyable experiences. Additionally, it effectively helps locate monuments in crowded tourism settings. The findings of this research make a valuable contribution to the ongoing discussion regarding the impact of evaluating MAR user interfaces on increasing visitor engagement with tourist destinations.},

abstract = {Fault analysis (FA) is the process of collecting and analyzing data to determine the cause of a failure. It plays an important role in ensuring the quality in manufacturing process. Traditional FA techniques are time-consuming and labor-intensive, relying
heavily on human expertise and the availability of failure inspection equipment. In semiconductor industry, a large amount of FA reports are generated by experts to record the fault descriptions, fault analysis path and fault root causes. With the development of Artificial Intelligence, it is possible to automate the industrial FA process while extracting expert knowledge from the vast FA report data. The goal of this research is to develop a complete expert knowledge extraction pipeline for FA in semiconductor industry based on advanced Natural Language Processing and Machine Learning. Our research aims at automatically predicting the fault root cause based on the fault descriptions. First, the text data from the FA reports are transformed into numerical data using Sentence Transformer embedding. The numerical data are converted into latent spaces using Generalized-Controllable Variational AutoEncoder. Then, the latent spaces are classified by Gaussian Mixture Model. Finally, Association Rules are applied to establish the relationship between the labels in the latent space of the fault descriptions and that of the fault root cause. The proposed algorithm has been evaluated with real data of semiconductor industry collected
over three years. The average correctness of the predicted label achieves 97.8%. The method can effectively reduce the time of failure identification and the cost during the inspection stage.},

abstract = {Intraoral scanners (IOS) are essential tools in dental prosthodontics, enabling efficient digitization of dental arches for CAD-CAM workflows. The Primescan IOS (Dentsply Sirona) can be fitted with three scanning sleeves, based on the level of hygiene imposed by the clinical situation and health regulations: a standard sleeve (SS), an autoclavable sleeve (AS), and a disposable sleeve (DS). Most studies evaluating accuracy use local best-fit algorithms to superimpose a reference scan and a test scan, providing relative accuracy. This study proposes an alternative evaluation method based on metrological principles and aims to compare the quality of scans taken with the three types of sleeves. An 8 mm aluminum oxide sphere was scanned 24 times using each sleeve. Mesh analysis was conducted, and measures of trueness, precision, and digitizing noise were calculated. Significant differences in trueness were identified between AS-DS (p < 0.001) as well as AS-SS (p < 0.001), while no significant differences were found between the sleeves for precision (p = 0.623). Significant differences in digitizing noise were also identified between DS-AS (p < 0.001), DS-SS (p = 0.001), and SS-AS (p = 0.001). This study tested the scanning quality of an IOS fitted with different sleeves using absolute measures as opposed to relative measures, and though statistically significant differences were found, within the experimental conditions, the errors appear to be within clinically accepted limits.},

However, they may ignore the effect of trust-building in the online platform and how trust affects the optimal strategy in the recycling platform. Consumers must consider the price and credibility in the product recycling process due to the differentiated prices for the same products set by different online platforms. This work studies the profit of recyclers and platforms with a degree of trust-building in the reverse logistics system considering the following scenarios: online recycling platform builds trust or not under centralized and decentralized models. The results show that trust-building can effectively make more revenue for the system of the online recycling platform with enhanced demand if the cost of the trust-building construction is relatively low, especially in the centralized model. The revenue-sharing contract is more profitable than the cost-sharing contract but fails to achieve optimization in the integrated setting. We find a new decision support tool for optimal strategies under different decision-making models. This work helps the recycling platform improve mechanism design and make optimal decisions considering trust-building.},

abstract = {Drones are increasingly used for last-mile delivery due to their speed and cost-effectiveness. This study focuses on a novel locker-drone delivery system, where trucks transport parcels from the warehouse to lockers, and drones complete the final delivery. This system is ideal for community and intra-facility logistics. The research optimises the network design by determining the location of lockers, the number of drones at each locker, and the assignment of demands to lockers, minimising operating costs. Both single-parcel and multi-parcel capacity drones are examined. We build an optimisation model for each system, considering drone service capacity as a critical constraint. We design an algorithm combining average sample approximation and a genetic algorithm to address demand uncertainty. The algorithm's efficiency is validated through comparative analysis with Gurobi. Numerical experiments, using real and generated data, optimise the network design. Results show that the multi-capacity drone system requires fewer lockers and drones than the single-capacity system. Although the single-capacity system yields lower drone delivery costs, it incurs higher truck delivery costs. Additionally, a comprehensive cost analysis compares the cost-efficiency of the locker-drone system with a conventional drone delivery system, revealing the cost-saving advantage of the locker-drone system.},

gathered using an online survey involving a sample of 486 French consumers. We
empirically tested the relationships among four factors: attitude toward buying wine
based on SM recommendations, perceived risks, intention to buy wine on SM, and
consumer intention to become an SM wine cooperator. Findings indicate that the
intention to be an SM wine cooperator is positively correlated with attitude toward
buying wine based on SM recommendations and the intention to purchase wine on
SM. To finish with, we link the concept of the consumer wine co-op to the current
debate in the literature on centralized versus decentralized (built on top of blockchain
networks) social media platforms, opening the door for future research avenues.},

abstract = {The potential influence of natural ecosystems on human health has been widely acknowledged globally. Nevertheless, the causality of such a correlation among the middle-aged and older populations in developing countries awaits further investigations. This study aims to understand how a specific natural ecosystem change, namely the establishment of ecological reserves, improves the physical and mental health of middle-aged and older residents in China. Two batches of national key eco-function zones (NKEFZs) in 2011 and 2016 are selected as a quasi-experiment; and a total of 128,755 middle-aged and older residents from a combined data set from the China Family Panel Studies (CFPS) and China Health and Retirement Longitudinal Studies (CHARLS) from 2010 to 2020. A difference-in-differences method was used to identify the causal effects of the natural ecosystem improvement on human health outcomes. The results indicate significant and sustained improvements in the physical health of local middle-aged and elderly residents following the implementation of the NKEFZs policy. Notably, ecological reserves with a water conservation function and those in Karst area have the most salient effects on physical health. Furthermore, this study shows that the creation of ecological reserves improves the mental health of middle-aged and older residents, with the effect varying based on changes in physical health. This study provides new insights into the positive impact of natural ecosystem improvement on human health outcomes, in particular physical and mental health.},

To push the limits of what is feasible with reasonable computational resources, extraction algorithms use cutoffs and minimality criteria.
In this article, we review the principles of extraction algorithms and we show that there are important differences between critical sequences extracted in the context of safety analyses and those extracted in the context of cybersecurity analyses. Based on this thorough comparison, we introduce a new cutoff criterion, so-called footprint, that aims at capturing the willfulness of an intruder performing a cyberattack. We illustrate our presentation by means of three case studies, one focused on the analysis of failures and two focused on the analysis of cyberattacks and their effects on safety. We show experimentally the interest of the footprint criterion.},

All businesses are finding it difficult to figure out how to enhance the environment and society. Following the co-generation of social, ethical, and corporate aims, new sustainable inventions have evolved since the COVID-19 pandemic event, similar to new solutions into a workable, viable, and ethical business. The positive and negative aspects of inventions are a topic of discussion among innovation management academics. In particular, how innovation may be more sustainable even when job inequities caused by automation have sparked a feeling of the importance of upholding human rights. Despite that, the innovation management literature is still far from being pedantic in studying automation and human rights towards sustainable innovations in the context of international new ventures (INVs). The article challenges a pessimistic view of innovations by examining automation and human rights for 3000 INVs through the perspective of the micro-foundations. Multiple linear regression analysis is used to evaluate hypotheses, demonstrating how social entrepreneurship can play a constructive mediating role in upholding human rights and promoting automation. This demonstrates the necessity for additional research on a business's individual level to create social breakthroughs. The study encourages policymakers and the government to support sustainable innovations by utilizing technology to boost job quality, uphold human rights, and foster global entrepreneurship.},

The growing demand for lightweight and reliable materials in hydrogen vessel reservoirs, intended for future vehicles, necessitates understanding the fast dynamic behavior (crash) of these materials for effective structural design in such applications.
This study presents an optimized approach for experimentally characterizing the overall dynamic mechanical behavior of Twill woven glass fiber reinforced polypropylene (W-GF-PP) laminates. The methodology focuses on reporting the strain rate effect on the
material response while attempting to isolate the inherent inertial disturbances in the specimen attributed to the test system. Tensile tests have been conducted until the specimen's total failure for three specific relative orientations of fiber: 0°, 90°, and ± 45°. The tests
span a strain rate range from quasi-static (10-4 s?1) up to 2000 mm?s?1 (approximately 160 s?1, depending on the specimen's actual response). The material's behavior appears sensitive, particularly for the ± 45° fiber orientation. The study also examines the impact of
the manufacturing process type on the dynamic behavior of the reinforced polypropylene.},

abstract = {This paper proposes a new proportional-sharing approach for fixed cost allocation (FCA) among a group of decision-making units (DMUs) based on data envelopment analysis (DEA). We first prove the proportional invariance in DEA-based FCA. Then, we show that the ?all-efficient? assumption in existing models usually leads to the use of unrealistic weights in efficiency analysis. To address this issue, we relax this assumption and adopt a weight constraint approach. Further, we illustrate that some DMUs would always be allocated with zero fixed cost if only the goal of efficiency maximizing is considered. Therefore, some weight constraints are added, and a new bi-objective model is proposed to allocate the fixed cost among the DMUs in order to simultaneously maximize the efficiencies of the DMUs and make the allocation as close as possible to the one generated according to the DMUs' operation sizes. A mono-objective nonlinear program, which can be solved using dichotomy and a linear program solver, is used to obtain a non-dominated or Pareto-optimal trade-off solution for the bi-objective model. With the use of our approach, neither unrealistic weights nor zero fixed cost appears in the result. Finally, the proposed approach is applied to a numerical example and a commercial bank case study.},

regime were performed under fully reversed total strain amplitudes from 0.6%
to 1.2%. The AA2024-T351 alloy exhibited cyclic hardening until failure. Symmetric
high cycle fatigue tests were also performed and the parameters for
fatigue life estimation using the Manson-Coffin-Basquin model were identified.
Elasto-plastic behavior was analyzed through stress-strain hysteresis
loops, evaluating kinematic and isotropic hardenings. Kinematic hardening
was found to be strain amplitude dependent, unlike the isotropic hardening.
The evolution of the isotropic variable with the percentage of fatigue life could
be described by an exponential law. Fractography investigations showed crack
initiation at the specimen border with quasi-cleavage and then crack propagating
by striation before ductile fracture.},

abstract = {Augmented reality has emerged as a transformative technology, with the potential to revolutionize the tourism industry. Nonetheless, there is a scarcity of studies tracing the progression of AR and its application in tourism, from early exploration to recent advancements. This study aims to provide a comprehensive overview of the evolution, contexts, and design elements of AR in tourism over the period (2002-2022), offering insights for further progress in this domain. Employing a dual-method approach, a bibliometric analysis was conducted on 861 articles collected from the Scopus and Web of Science databases, to investigate the evolution of AR research over time and across countries, and to identify the main contexts of the utilization of AR in tourism. In the second part of our study, a systematic content analysis was conducted, focusing on a subset of 57 selected studies that specifically employed AR systems in various tourism situations. Through this analysis, the most commonly utilized AR design components, such as tracking systems, AR devices, tourism settings, and virtual content were summarized. Furthermore, we explored how these components were integrated to enhance the overall tourism experience. The findings reveal a growing trend in research production, led by Europe and Asia. Key contexts of AR applications in tourism encompass cultural heritage, mobile AR, and smart tourism, with emerging topics such as artificial intelligence (AI), big data, and COVID-19. Frequently used AR design components comprise mobile devices, marker-less tracking systems, outdoor environments, and visual overlays. Future research could involve optimizing AR experiences for users with disabilities, supporting multicultural experiences, integrating AI with big data, fostering sustainability, and remote virtual tourism. This study contributes to the ongoing discourse on the role of AR in shaping the future of tourism in the post COVID-19 era, by providing valuable insights for researchers, practitioners, and policymakers in the tourism industry.},

abstract = {Purpose
This paper conceptually aims to discuss the dual role of knowledge management (KM) and technological innovation, which brings about innovations, although it can be limited by psychological and emotional ownership.
Design/methodology/approach
This study examines the real impact of the paper on KM and technological innovation in family small to medium enterprises (FSMEs). This is a unique context affected by psychological and emotional ownership. However, COVID-19 has forced FSMEs to consider new strategies and practices to preserve their competitive advantage.
Findings
In this scenario, knowledge exchange, knowledge absorption and technology adoption appear relevant to the innovation process. This study offers a framework for how the duality of KM and technological innovation affects innovation.
Originality/value
Although extant research has explored technological innovation outcomes, a literature review reveals that accumulated studies on the drivers of technological innovation and KM in the context of FSMEs require further inquiry. Family members' emotional ownership may foster KM because identification with organizational goals enhances individuals' willingness to access and share information and stimulates new products and technological development.},

We propose two FCA principles from individual rationality: a novel self-lowest principle and the efficient after FCA principle. Under the precondition that the individual rationality principles are satisfied, we suggest determining the final FCA result based on two overall fairness principles: the lower bound principle and the cross-efficiency Pareto-optimality principle. A multi-objective FCA model is built following these principles. An algorithm and some rules are used to solve the multi-objective model and obtain the final cross-efficiency evaluation and FCA result. Our study contributes by explicitly showing the design of individual rationality and overall fairness in FCA using the DEA cross-efficiency evaluation mechanism. Finally, we compare the suggested approach with some previous ones using a numerical example and illustrate its usefulness through a truck fleet case study.},

Applying bibliometric analysis, this study found publication trends, prolific journals, influential articles, and major themes in the field, whereas the TCM framework helped identify widely used theories (motivation theory, immigration theory, acculturation theory, learning theory, and capital theory), research contexts (destination country or region, population, and others), and methods in research and provided future study directions. The identified gaps in the existing literature suggest that future research should develop theoretical foundations and research designs to analyze new processes, patterns, and issues in ISM in higher education within the context of today's changing international environment. In addition to identifying the key research themes and research foundations of ISM in higher education, this review can help add value to the ISM literature from a marketing perspective. This is the first comprehensive literature review of this topic using a hybrid approach.},

abstract = {The established literature demonstrates the critical role of the policy mix in the formulation and implementation of government policies for industrial upgrading. However, existing studies mainly examine the policy mix from either a horizontal or a vertical coordination perspective; very few examine both dimensions. To gain further insights, the current study involves an analysis of how China's central government manages horizontal and vertical coordination to pursue upgrading in manufacturing industries on the basis of an ambidextrous policy mix perspective and a thorough examination of both the external attributes (i.e., policy level) and content (i.e., policy instruments and themes) of policy documents. This analysis reveals several viable policy implications in relation to China's manufacturing transformation. In particular, it finds that China's policy mix for achieving manufacturing upgrading is highly coordinated on both horizontal and vertical dimensions. Governments at all levels apply the same set of policy instruments; environmental instruments are the most frequently used, followed by supply- and demand-side instruments. The core policy topics within the manufacturing upgrading structure include innovation, industrial transformation, industrial agglomeration, demonstration projects and service-oriented manufacturing. Therefore, this study establishes recommendations for future policies, which should focus on reinforcing guidance regarding national policies, encouraging local governments to apply innovative policy tools and increasing the use of demand-side policy instruments.},

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.},

journal = {International Journal Of Retail & Distribution Management},
abstract = {Purpose - Despite the increasing use of home delivery (HD) in e-commerce, no studies have explicitly
examined consumer perceptions of the convenience of the last-mile delivery of goods by cargo bike (CB).
Therefore, this study aims to identify the dimensions of HD convenience and to develop a reliable and valid
measurement tool, namely the Home-Delivery Convenience via Cargo Bike (HDCCB) scale.
Design/methodology/approach - The methodology of this scale development study is premised on a
review of the existing literature, which identifies differences in consumer perceptions of the convenience of
services. The authors conducted semi-structured interviews with 10 online consumers and validated the
content with 3 experts on marketing in the retail and services sectors in order to develop the items for the scale.
Thereafter, the authors identified the main dimensions through an exploratory factor analysis that the authors
applied to an online survey with 116 respondents. Finally, the scale was validated through a confirmatory
factor analysis of an online survey with 300 respondents.
Findings - Following the original work of Brown (1990), the authors define consumer perceptions of HD
convenience as a multidimensional construct and measure each facet of its four dimensions, which are time, use,
execution and acquisition. E-retailers and last-mile logistics providers could use the authors' proposed
measurement tool to assess consumer perceptions of the convenience of HD. That assessment could generate a
competitive advantage.
Originality/value - This study is original as the study deepens the existing understanding of consumer
perceptions of the convenience of HD by CB in last-mile logistics. This study also develops a multidimensional
measure that is based on an empirical study.},

In particular, with the growing development of crowdfunding models, scholars and practitioners are questioning how backers can cocreate value by funding new entrepreneurial initiatives through digital platforms dedicated to this new form of financial support. Therefore, positioning this article in the knowledge and engineering management literature, the current research explores whether two subdimensions of value cocreation (VCC), knowledge sharing and interaction, may help to understand backers' intention to participate in a reward-based crowdfunding (RBCF) campaign. In particular, using the partial least square structural equation modeling approach on an original sample of 3574 backers, in this article, we find that knowledge sharing, understood as backers' expertise as well as the preparedness of the proponent team, and the interaction between the campaign actors contribute to explaining backers' participation in an RBCF initiative. The research supports the relevance of backers' engagement in terms of VCC as an experiential benefit for the success of an RBCF initiative. From this perspective, our study suggests that both entrepreneurs and platforms should consider VCC in the design and setting of RBCF campaigns.},

However, this approach is computationally expensive especially when stacked structures are analyzed. Thus, the positioning of the mobile platform for the mechanism is analyzed using the theory of Tilt & Torsion (T&T). The singularity-free workspace and the tilt limits of the mechanism are disclosed through this method. These workspaces can then be mapped to the Euler angles of the universal joint and the relation between the T & T space and the Euler space is demonstrated and validated in this study. Initially, simulations are performed using the results of singularity analysis to have a comparison between the T&T space and the Euler space. Experimental validation is then carried out on the prototype of the mechanism to perform a circular trajectory, in line with the simulations. The outcome of this study will be helpful for the integration of the mechanism for a piping inspection robot and also for the analysis of stacked architectures.},

In this paper, we present PalmEx, a novel approach which incorporates palmar force-feedback into exoskeleton gloves to improve the overall grasping sensations and manual haptic interactions in VR. PalmEx's concept is demonstrated through a self-contained hardware system augmenting a hand exoskeleton with an encountered palmar contact interface -- physically encountering the users' palm.
We build upon current taxonomies to elicit PalmEx's capabilities for both the exploration and manipulation of virtual objects.
We first conduct a technical evaluation optimising the delay between the virtual interactions and their physical counterparts.
We then empirically evaluate PalmEx's proposed design space in a user study (n=12) to assess the potential of a palmar contact for augmenting an exoskeleton. Results show that PalmEx offers the best rendering capabilities to perform believable grasps in VR.
PalmEx highlights the importance of the palmar stimulation, and provides a low-cost solution to augment existing high-end consumer hand exoskeletons.},

journal = {International Marketing Review},
abstract = {Purpose
A paucity of studies has used a microfoundation lens to examine servitization processes in internationalized knowledge-intensive business service (KIBS) companies. The research aims to bridge this gap by considering knowledge sharing as a form of both codified knowledge and informal feedback knowledge; it also assesses whether the adoption of knowledge transfer and translation practices in a servitization process positively moderates the effect of knowledge transformation on knowledge sharing for internationalized KIBS companies.
Design/methodology/approach
By adopting a microfoundation lens, the research offers an empirical analysis to identify the relations between codified and tacit knowledge in servitization processes within internationalized KIBS companies. The study is based on 326 respondents from 30 KIBS companies. A multiple regression analysis was used for hypotheses testing.
Findings
The authors found significant relations among the use of electronic documents in the servitization process (formal codified knowledge), personal advice in servitization (informal feedback knowledge) and knowledge sharing in internationalized KIBS companies. Findings also support the indirect effect assumed in the hypothesis between knowledge transformation and knowledge sharing in internationalized KIBS companies, which is positively moderated by the adoption of cross-cultural knowledge practices in the servitization process.
Originality/value
To the best of the authors' knowledge, this research provides the first conceptual model of the use of a microfoundation lens to examine knowledge sharing in internationalized KIBS companies. The micro level features individual knowledge sharing in the servitization process, while the meso level focuses on knowledge transformation in KIBS companies and the adoption of knowledge transfer and translation practices in the servitization process.},

In particular, the theoretical contribution of this paper is to combine Labour Process with psychoanalytically-informed, post-structuralist theory, in order to connect to, and further our understanding of, how and why digital workers assent to, or oppose, the interpellations of algorithmic ideology at work. To illustrate the operation of affective control in the Platform Economy, the emblematic example of ride-hailing platforms, such as Uber, and their algorithmic management, is revisited. Thus, the empirical section describes the way drivers are glued to the algorithm (e.g. for one more fare, or for the next surge pricing) in a way that prevents them, although not always, from considering genuine resistance to management. Finally, the paper discusses the central place of ideological fantasy and cynical enjoyment in the Platform Economy, as well as the ethical implications of the study.},

abstract = {The use of social media offers tremendous innovation potential. Yet, while cur-rent research emphasizes success stories, little is known about how firms canleverage the full potential of their social media use for open innovation. In thispaper, the authors address this gap by conducting a configurational analysis todevelop an integrative taxonomy of social media-enabled strategies for openinnovation. This analysis stems from the integration of internal and externalvariables such as social media communication activities, organizational inno-vation seekers, potential innovation providers, the stages of the open innova-tion process, and their relationship with different performance outcomes andbarriers to social media adoption for open innovation. Through an empiricalstudy of 337 firms based in eight countries, four clusters have been identifiedthat are characterized as distinct strategies:?marketing semi-open innovators,??cross-department semi-open innovators,??cross-department full processsemi-open innovators?and?broad adopters open innovators.?The findingsreveal the trade-offs associated with different strategies for implementingsocial media for open innovation and provide insights of the use of these strat-egies. By doing so, they suggest a more nuanced approach that contrasts withthe traditionally positive (or even rosy) depiction of the effects of social mediaon open innovation. Accordingly, managers are encouraged to contemplatetheir organizational competencies, capabilities, and their strategic intent whendrafting social media strategies for open innovation. Selective approaches,along with greater adoption leading to greater benefits, are shown to be morerewarding than a middle way that spreads things too thin. Avenues for furtherresearch include qualitative explorations of the trajectories unfolding throughimplementing social media strategies for innovation activities and the use ofobjective performance measures rather than subjective perceptions from informants to understand the complex relationships between social mediaadoption and performance.},

We specifically investigate two types of organizational learning, direct learning by own patent litigations and indirect learning by others' litigations, and their influence on patent production and financial performance. Based on an analysis of the semiconductor industry, we find that (a) plaintiff firms have reduced patent production, (b) industry litigation intensity further diminishes the plaintiff firms' patent production, (c) plaintiff firms have enhanced financial performance, and (d) industry litigation intensity further strengthens the plaintiff firms' financial performance.},

abstract = {While the ideas of contemporary French philosopher Alain Badiou have been largely influential on literature, art humanities, political sciences, government laws, cultural studies, and even education, geography and religion studies - including noticeable exegeses in the Anglo-Saxon world from Slavoj ?i?ek, Simon Critchley and Ed Pluth - their use in organization studies remains, perhaps startingly, marginal. Further, existing Badiouian organizational studies focus mainly on Being and Event but much less on his two other major opuses: Theory of the subject and Logics of World. The novelty of Badiou is to consider subjects at the interaction between language and psycho-sexual, traumatic experiences, which remain impossible to symbolize and thereby constitute political events. The notion of evental change does not bring about a new world on its own, but it requires a series of acts in a context, a form of faithfulness to the event - a performance which this paper further investigates.
Going beyond the current use of Badiou in organization studies, we propose a Badiouan theoretical framework to address organizational subjects' performativity, in terms of subjectivation (anxiety, courage) and subject-process (superego, justice), whose articulation gives rise to four various modes of affective acting (terror, skepticism, dogmatism and confidence). A framework comprising these modes of affective acting is aimed to support subjectivities intended to drive change in society, and to avoid those subjectivities favouring the status quo. Therefore, Badiou's approach is highly relevant for the cultivation of subjectivities promoting alternative goods, rather than focusing on critique and resistance.
To illustrate the relevance of this framework empirically, we offer a Badiouian interpretation of antiwork politics, a left-wing social movement which is either mocked or coopted by corporatism - and loses its radicality. As subjectivity is progressively manipulated and colonized by management, the novel application of Badiou's framework to the anti-work problem enables to revive the political and ethical dimension of work psychodynamics that is lost through individualistic and intra-psychic focus.},

abstract = {La vidéosurveillance s'est considérablement développée ces dernières années. Les sources sont de plus en plus nombreuses, en mouvement ou avec des qualités variables : on parle de système distribué. L'analyse des données produites par de tels systèmes est devenue un enjeu majeur. En effet, si la détection des objets et des actions capturés par une caméra individuelle est aujourd'hui accessible à travers les modèles d'apprentissage automatique ou de reconnaissance de forme, la modélisation et la détection automatique d'évènements longue durée et faisant intervenir un réseau de caméras de surveillance restent un défi.
Ainsi, comment permettre la détection d'évènements complexes dans un réseau de caméras de surveillance hétérogènes et distribuées ?
Afin de répondre à cette problématique, nous proposons un framework pour l'extraction et l'enrichissement de caractéristiques à partir de caméras de vidéosurveillance. Il repose sur 1) un pipeline de modèles de Deep Learning pour l'extraction de caractéristiques de vidéos (extraction d'images-clés, détections d'objets / segmentation d'instances, extraction d'attributs, détection de relations spatiales, réidentification), 2) un module de génération d'un graphe de connaissances, 3) un module d'enrichissement du graphe pour améliorer la qualité des détections, et 4) un module d'analyse pour la détection d'événements complexes sur le graph. Son architecture modulaire permet d'interchanger les étapes d'extraction de caractéristiques provenant des vidéos. Le poster détaillera le framework proposé et illustrera le processus de création du graphe à partir de vidéos provenant du benchmark Smart-City CCTV Violence Detection Dataset (SCVD).
L'intérêt de l'approche est de pouvoir, à terme, se focaliser sur la sémantique des vidéos comme l'isolation de segments vidéo ou d'actions (filtres/projections sur le graph), la détection d'événements ou activités au moyen d'algorithmes de Graph Mining / GNN.},

abstract = {This article presents the design and analysis of a series-parallel hybrid tensegrity mechanism. The mechanism has two stages which consist of a fixed base, an intermediate mobile platform, and a mobile end-effector. Each stage is connected by three tension springs and a universal joint in the center. By correlating to a 3-SPS-U architecture, the geometrical equations for the mechanism are generated in the Euler space and the Tilt & Torsion space. To simplify the computations, the Tilt & Torsion space is employed for the analysis of the mechanism. A stability analysis is carried out initially to identify the design parameters of the mechanism in the static mode through an optimization approach. By employing algebraic methods, the singularity analysis is then carried out on the hybrid mechanism. The results of this analysis helped in identifying the feasible workspace and the maximum tilt limits of the architecture. A mapping equation that demonstrates the relation between the Tilt & Torsion angles and the Euler angles is then presented using the results of singularity analysis. A numerical simulation is then demonstrated to validate the results of the analysis. The mechanism under study is then proposed to be integrated into a piping inspection robot for passing through elbows and T-sections.},

The Tala Sound project studies whether non-Western music from the southern regions of India can be used to improve the mood and functional abilities of Western people suffering from Alzheimer's disease. This traditional style of music, called Carnatic music, is based on specific rhythm sequences, called "talas", that have an irregular rhythm compared to the ones found in Western music. In this paper, we describe the Tala Box, a new multimedia sensory device with which patients can interact while a Carnatic song is being played. The motivation for the development of this embedded system is the intent, in addition to the unusual nature of the music played, to use motor and cognitive stimulation to better engage Alzheimer's patients and, hopefully, improve their mood and mental state. Preliminary testing with healthy seniors has shown great interest in the Tala Box.},

This kind of generation being prone to combinatorial explosion, our algorithm embeds state-space reduction capabilities focused on the specificities of cyber-physical attacks.
Finally, we illustrate the performance of our algorithm on a case study: the navigation system of an autonomous vessel.

It relies on knowledge integration (by business rules) and unsupervised machine learning, with a Gaussian Mixture Model, applied to in-process monitoring signals. The method was evaluated on real industrial machining databases collected during one year. Manual data mining shows that this method is accurate on industrial production (98.9%).

While typical harmonic analysis is based only on notes or on an audio signal, our analysis takes a hybrid approach by quantifying different types of interactions between the spectra of notes. These quantifications, which we call Harmonic Descriptors, are derived from acoustic or perceptual models. Three such descriptors are defined and mapped: concordance, third order concordance and roughness.
Harmonic analysis based on spectral structures opens new possibilities beyond traditional note-only or signal-only approaches. They can be applied to a continuum of frequencies, independent of the tuning system, as well as historical and stylistic constraints. Harmonic Maps based on spectral structures can be especially relevant to study the relationship between timbre and harmony. Our interactive exploration of harmonic spaces can have applications for analytical, compositional and educational purposes.},

abstract = {Additive manufacturing of silicone is increasingly being explored to complement the traditional molding fabrication technique for Soft Pneumatic Actuators (SPAs). However, the mechanical behavior of SPAs is defined by their 3D form, which leads to prioritizing the SPAs mechanical properties over their aspect. In this paper, we propose a novel SPA fabrication method where the mechanical properties of a silicone part are defined during the fabrication phase rather than the 3D modeling phase, leading to the object's mechanical properties being independent of the object's aspect. This novel SPA fabrication method, named Local Layer Splitting (LLS), consists of local modifications of the printing layer height to integrate stiffness variation, thus generating controlled mechanical deformation when pressured. We discovered that silicone printing layer height impacts the final stiffness of the material, and it could be used to program bending deformation to actuators during printing. We first characterize the effect of the layer height parameters on 3D-printed silicone stiffness with tensile tests. Then, we present a custom slicer we developed to generate G-codes with local layer height variations depending on the x and y positions. We then characterize the bending and force achievable by SPAs made with the LLS process and find that they match those of state-of-the-art SPAs. Finally, we present and discuss how the LLS method impacts the SPAs design by shifting the bending behavior integration from the SPAs 3D conception to their fabrication phase.},

We evaluate a tablet-based interface where users gesturally control the pitch of a pre-recorded utterance by drawing curves on the touchscreen. 24 subjects (12 French learners, 12 British controls) imitated English phrases with their voice and the interface. Results of an acoustic analysis and expert perceptive evaluation showed that learners' gestural imitations yielded more accurate results than vocal imitations of the fall-rise intonation pattern typically difficult for francophones, suggesting that PVS can help learners produce intonation patterns beyond the capabilities of their natural voice.},

abstract = {The thermocompression molding process allows composites to be made with longer fibers compared to injection molding and extrusion. However, during thermo-compression molding fiber-reinforced composites are exposed to complex effects, which can lead to specific fiber orientation/distribution and therefore affect the mechanical properties. The aim of this work is to study the effect of fiber orientation on the mechanical properties of the long-glass-fiber-reinforced polypropylene (GF50-PP) composite produced by the thermocompression process. Moreover, due to the application of this composite in cold liquid gas storage, it is interesting to study this effect under cryogenic conditions. In this study, composite plates of GF50-PP were cut to analyze the effect of fiber orientations: 0°, 45°, and 90° with respect to the Mold Flow Direction (MFD). After microstructural observations by SEM microscopy and physico-chemical analysis, the mechanical behavior of GF50-PP samples was examined at monotonic tensile loading and tension-tension fatigue at two loading temperatures of 20°C and -70 °C. The results of the tensile tests revealed that the values of stress at break were almost similar at 20°C and -70°C for different fiber orientations of 0°, 45° and 90° and that the temperature effect for the two test conditions is almost insignificant. The tensile-tension fatigue tests at 20°C show the significant effect of the orientation of the fibers when the amplitude of deformation is important. On the other hand, when the amplitude is small, this effect is negligible. In this case, all samples exhibit almost the same behavior. However, during fatigue tests at -70 ° C (cryogenic temperature), the material shows almost uniform linear behavior, but still sensitive to the orientation of the fibers.},

abstract = {L'analyse par éléments finis est largement utilisée pour la prédiction du retour élastique, mais la précision dépend fortement des paramètres numériques et physiques. Parmi les paramètres qui affectent la prédiction, on peut citer : le coefficient de frottement, les lois de comportement, la fonction de charge... Dans ce papier, la sensibilité des coefficients de frottement et l'influence d'extrapolation des lois sur la prédiction du retour élastique sont étudiées et analysées. Comme application, nous utilisons un exemple industriel du procédé d'emboutissage : le bavolet d'automobile avec le matériau HSLA420. Toutes les simulations numériques sont effectuées avec le code commercial Pam-stamp 2G.},

abstract = {With the increasing demand of raw materials nowadays, and the decrease in supplies, the industrial sector is suffering, while the environment and the society are also indirectly affected. The goal to reach a sustainable development imposes several studies on the economic, environmental and community level. The aim of this paper is to provide an overview of the existing literature on automating remanufacturing, and its impacts on the three pillars of sustainability. The outcomes of this study will reveal the impacts of remanufacturing on sustainability and will conceptualize the impact of using automation and cobots, which are among the key concepts in industry 4.0. The investigation that covers each part of the remanufacturing process will help in formalizing an approach about the automation of such processes and improve the remanufacturing sector towards a more sustainable industry.},
