Abstract:
Ces colloques se sont tenus à Rome, à l’Université pontificale Saint-Thomas d’Aquin (Angelicum), en novembre 2022, sous le patronage du Dicastère pour la promotion de l’Unité des chrétiens et du Secrétariat du Synode des évêques. Le pape François est revenu à plusieurs reprises sur cette vision, en particulier depuis le lancement du chemin synodal aux divers niveaux de l’Église catholique, en préparation du Synode des évêques sur la synodalité annoncée pour octobre 2023. Dans cette perspective, la Fondation Pro Oriente (Vienne) et l’Institut d’études œcuméniques de l’Angelicum ont organisé trois colloques œcuméniques internationaux sur le thème : « À l’écoute de l’Orient », dans le but d’explorer ce que l’Église catholique peut apprendre des traditions orientales sur la synodalité.

Abstract:
Une fouille archéologique préventive, réalisée à l’angle des rues Appian et des Fossés-de-Trion à Lyon (Métropole de Lyon), a permis de mettre en évidence deux tranchées parallèles datées de l’époque augustéenne. Une fonction drainante ou l’existence de chemins creux sont des hypothèses à écarter. La découverte d’un ensemble important de fragments de tuyaux en terre cuite retrouvés en vrac dans le comblement de l’une des deux tranchées pourrait orienter la réflexion vers la présence d’un ancien aqueduc dans ce secteur en marge de la ville antique.

Abstract:
Cet article se pmpose d'examiner quelques textes de Thomas d'Aquin, qui laissent entrevoir une pensée du divin semblable à celle de Heidegger, lorsque ce dernier aborde le concept de « Gôttliche » qui dépasse les catégories de la scolastique et ne s 'attache pas à une « étantité » particulière. La métaphysique devient alors une échelle qui n 'est pas seulement à gravir — ce qui fut le cas des deux « Summa » — mais aussi à laisser tomber, une fois que l'accès à une pensée autre de Dieu devient possible, à l'instar de l'apophatisme oriental. Et si l'Aquinate sonde le caché, le secret et l'indicible, il ouvre cependant le chemin au sens de la chose, thème central chez Heidegger, vu comme le lien privilégié entre les hommes et la divinité. L'étude de ces textes laissent alors entrevoir une nouvelle théologie, dépassant la positive et la négative. Elle se profile à l'horizon des derniers écrits de Thomas, tout en étant présente derrière les indications formelles des travaux de Heidegger sur le divin.

Abstract:
Après quelques considérations sur les diverses classifications qui peuvent être établies à propos des chemins, classification réalisée selon leurs caractéristiques, leur utilisation et leur propriété, nous trouvons ici pour nous orienter, une bibliographie plus approfondie que celle que l’on aurait pu imaginer, mais, en bien des aspects non définitive encore, principalement en ce qui concerne les analyses archéologiques du thème. En partant du réseau de voies romaines, utilisées et réparées pendant le Moyen-Age, on examine plus spécialement les documents concernant les routes principales et secondaires qui continuent à être utilisées, en s'arrêtant tout particulièrement sur les ponts de bois et de pierres construits pendant le Moyen-Age et plus spécialement ceus du XIeme siècle (les ponts romans) et ceux du XIVeme (les pont gothiques). On prête une attention encore plus particulière aux deux seuls qui aient été minutieusement mis à jour jusqu'ici, dans la vallée du Llobregat et qui permettent de connaître les caractéristiques et les époques de leur construction et de leurs réparations successives. Dans la conclusion il est fait référence aux barques et aux ponts des bateaux destinés à traverser les rivières principales telles le Sègre et l'Ebre. Le thème des chemins médiévaux catalans a été tour d'abord traité d'un point de vue régional, prospections et recherches directement sur le terrain sont encore nécessaires pour une connaissance plus approfondie.

Abstract:
Dans le paysage archéologique du Proche-Orient ancien, la chaîne montagneuse du Zagros, située à l’ouest de l’Iran, constitue à la fois un obstacle naturel et un carrefour d’influences culturelles entre deux civilisations majeures de l’ancien monde, celles du plateau iranien et de la plaine mésopotamienne. La région est un patchwork composé de vastes prairies propices à l’élevage et au nomadisme, ainsi que de larges vallées favorables à l’agriculture et à la sédentarité. Le nomadisme étant difficile à appréhender d’un point de vue archéologique, j’ai entrepris une enquête ethnographique pour comprendre ce mode de vie et mieux répondre à mes questionnements d’archéologue. La région du Luristan est encore aujourd’hui fréquentée par plusieurs tribus nomades. J’ai suivi au printemps 2021 des familles de la tribu Bakhtiari, depuis leur campement d’hiver au Khuzestan vers leur campement d’été au Luristan. J’ai essayé de comprendre leurs raisonnements, leurs choix et leurs stratégies afin de mieux appréhender les possibilités et les modalités d’un mode de vie nomade d’un point de vue archéologique. Identifier les traces laissées par les nomades actuels sur leur chemin de nomadisation permet de mieux discerner et interpréter celles laissées par les nomades anciens.

Gallia 71, no. 2 (2014): 3–46. http://dx.doi.org/10.4000/11q14.
Abstract:
Les tombes du milieu de l’âge du Fer des plaines languedociennes sont encore fort mal connues. La fouille préventive menée en 2004 sur le site de la Pailletrice, à Pérols, près de Montpellier, a livré quatre tombes à fossé circulaire de la fin du vie s. et du début du ve s. av. J.-C. Ces structures sont groupées à proximité immédiate d’un chemin empierré, attesté dès le dernier quart du vie s. av. J.-C. Pour la première fois dans cette région, l’état de conservation du gisement permet d’affirmer le caractère funéraire de tels cercles fossoyés. Le monument le mieux conservé montre un fossé périphérique limitant un tumulus de terre très bas, vers le centre duquel se trouvent un dépôt secondaire de crémation avec son ossuaire et les restes de deux vases en bronze, ainsi qu’une fosse peu profonde contenant des résidus du bûcher. Dans les fossés de tous ces monuments sont conservés des restes plus ou moins nombreux d’amphores et de vases à boire, témoins de possibles cérémonies auprès des tombeaux. Les données livrées par ce gisement sont insérées dans le contexte des pratiques funéraires du premier âge du Fer du Languedoc oriental.

Abstract:
Jeremey Parnow: un auteur soviétique qui se tourne vers lʼOrient Dans son livre De oosterse renaissance qui contient des réflexions critiques sur la culture actuelle, Han Fortmann se demande si la culture occidentale ne pourrait pas être guérie et enrichie par lʼintégration de certaines valeurs de la culture orientale. Ce à quoi il faudrait viser, selon lui, cʼest à un „comportement de base que lʼon pourrait indiquer par des mots comme: respect, confiance, amour, sincérité, réceptivité”. Il sʼagit dʼune „connaissance du coeur”, dʼune „façon de connaître qui nʼémane pas de lʼavoir mais suppose lʼêtre. Cʼest une „connaissance supérieure” dans la mesure où le dédoublement entre le moi et le monde serait neutralisé et lʼunité profonde retrouvée. En fait, Fortmann décrit ici précisément lʼattitude dʼesprit que lʼécrivain soviétique Jeremey Parnow exprime dans son livre intitulé Drakony Groma. Bien que déj à dans ses livres précédents il se montrât préoccupé des expériences intérieures de lʼhomme, Parnow témoigne dans son oeuvre récente dʼun grand intérêt pour la sagesse de lʼOrient. Il indique explicitement les sources de cette sagesse, comme le Tao Te Ching de Lao Tzeu, la littérature religieuse tibétaine, le symbolisme hindou et bouddhique et la poésie mystique dʼOmar Khaiîam. Puis il fait preuve de sa grande estime pour la vie méditative telle quʼelle est encore connue en Orient comme chemin vers la connaissance parfaite et lʼillumination. Tout cela est très remarquable pour un auteur qui publie en Union Soviétique. Le fait quʼun écrivain contemporain russe parle de ces choses spirituelles, et surtout le fait que cela est momentanément toléré dans la littérature soviétique officielle, donne à espérer.

Tarhini, Batoul. "Oriented paths in digraphs and the S-packing coloring of subcubic graph." Electronic Thesis or Diss., Bourgogne Franche-Comté, 2023. http://www.theses.fr/2023UBFCK079.
Abstract:
Cette thèse de doctorat est divisée en deux parties principales: La partie I explore l'existence de chemins orientés dans les digraphes, cherchant à établir un lien entre le nombre chromatique d'un digraphe et l'existence de chemins orientés spécifiques en tant que sous-digraphes. Les digraphes contenus dans n'importe quel digraphe n-chromatique sont appelés n-universels. Nous examinons deux conjectures : la conjecture de Burr, qui affirme que chaque arbre orienté d'ordre n est (2n-2)-universel, et la conjecture d'El Sahili, qui déclare que chaque chemin orienté d'ordre n est n-universel. Pour les chemins orientés en général, la meilleure borne est donnée par Burr, à savoir que chaque chemin orienté d'ordre n est (n - 1)²-universel.Notre objectif est d'étudier des chemins à trois blocs. Pour atteindre nos objectifs, nous nous appuyons fortement sur des concepts fondamentaux, y compris l'induction sur l'ordre d'un digraphe donné, les forêts finales, les techniques de nivellement et les méthodes de décomposition stratégique de digraphes. Un chemin comportant trois blocs est désigné par P(k1, k2, k3). Pour le chemin P(k,1,l), nous avons confirmé la conjecture d'El Sahili dans les digraphes Hamiltoniens. En se basant sur ce résultat pour les digraphes Hamiltoniens, nous avons confirmé la conjecture d'El Sahili pour une classe plus générale de digraphes, ceux qui incluent un chemin dirigé hamiltonien. Nous introduisons une technique novatrice : une décomposition du digraphe en sous-digraphes résultant d'une série d'opérations basées sur le fameux théorème de Roy, qui garantit l'existence d'un chemin orienté dirigé d'ordre n dans tout digraphe n-chromatique. Cette technique s'est avérée cruciale pour établir de nouvelles bornes linéaires pour le nombre chromatique de digraphes qui ne comportent pas de chemin orienté avec trois blocs. En effet, en utilisant cette technique, nous avons prouvé que le chemin P(k,1,l) satisfait la conjecture de Burr. De plus, pour n'importe quel chemin à trois blocs, P(k,l,r), nous avons établi une borne linéaire pour le nombre chromatique qui améliore toutes les bornes précédemment atteintes. Dans la partie II, nous étudions le problème de la coloration de packing dans les graphes. Étant donnée une séquence non décroissante S = (s1, s2, . . . , sk) d'entiers positifs, une S-coloration (de packing) d'un graphe G est une partition de l'ensemble des sommets de G en k sous-ensembles {V1, V2, . . . , Vk} tels que pour chaque 1 ≤ i ≤ k, la distance entre deux sommets distincts u et v dans Vi est d'au moins si + 1. Notre attention est centrée sur une conjecture intrigante proposée par Brešar et al., qui affirme que l'arête subdivision de n'importe quel graphe subcubique admet une (1,2,3,4,5)-coloration de packing. Notre objectif est de confirmer cette conjecture pour des classes spécifiques de graphes subcubiques et de traiter les questions non résolues soulevées dans ce domaine. Une observation de Gastineau et Togni indique que si un graphe G est (1, 1, 2, 2)-colorable, alors son graphe subdivisé S(G) est (1,2,3,4,5)-colorable, et donc il satisfait la conjecture. En nous basant sur cette observation et afin de prouver la véracité de la conjecture pour la classe des graphes de Halin cubiques, nous avons étudié leur S-coloration de packing visant à prouver qu'ils admettent une coloration en (1, 1, 2, 2). Nous avons prouvé que tout graphe de Halin cubique est (1, 1, 2, 3)-colorable, et donc (1, 1, 2, 2)-colorable, et ainsi nous confirmons la conjecture pour cette classe. De plus, Gastineau et Togni, après avoir prouvé que chaque graphe subcubique est (1, 2, 2, 2, 2, 2, 2)-colorable, ont posé un problème ouvert sur le fait de savoir si chaque graphe subcubique est (1, 2, 2, 2, 2, 2)-colorable. Nous répondons affirmativement à cette question dans la classe particulière sur laquelle nous avons travaillé : nous avons prouvé que les graphes d'Halin cubiques sont (1, 2, 2, 2, 2, 2)-colorablesThis PhD thesis is divided into two principal parts: Part I delves into the existenceof oriented paths in digraphs, aiming to establish a connection between a digraph'schromatic number and the existence of specific oriented paths within it as subdigraphs. Digraphs contained in any n-chromatic digraph are called n-universal. We consider two conjectures: Burr's conjecture, which states that every oriented tree of order n is (2n-2)-universal, and El Sahili's conjeture which states that every oriented path of order n is n-universal. For oriented paths in general, the best bound is given by Burr, that is every oriented path of order n is (n − 1)^2-universal. Our objective is to study the existence of an integer k such that any digraph with a chromatic number k, contains a copy of a given oriented path with three blocks as its subdigraph. To achieve our goals, we rely significantly on fundamental concepts, including, induction on the order of a given digraph, final forests, leveling techniques, and strategic digraph decomposition methods. A path P (k1, k2, k3) is an oriented path consisting of k1 forward arcs, followed by k2 backward arcs, and then by k3 forward arcs. For the path P(k,1,l), we have confirmed El Sahili's conjecture in Hamiltonian digraphs. More clearly, we have established the existence of any path P (k, 1, l) of order n in any n-chromatic Hamiltonian digraph. And depending on this result concerning Hamiltonian digraphs, we proved the correctness of El Sahili's conjecture on a more general class of digraphs which is digraphs containing a Hamiltonian directed path. We introduce a new technique which is represented by a decomposition of the digraph into subdigraphs defined by a series of successive operations applied to the digraph relying on the famous theorem of Roy which establishes the existence of a directed path of order n in any n-chromatic digraph. This technique has proven to be instrumental in establishing new linear bounds for the chromatic number of digraphs that lack an oriented path with three blocks. In deed, using this technique, we proved that the path P(k,1,l) satisfies Burr's conjecture.Moreover, for any path with three blocks, P(k,l,r) we establish a linear bound for the chromatic number which improves all the previously reached bounds. In Part II we study the problem of S-packing coloring in graphs. Given a non-decreasing sequence S = (s1, s2, . . . , sk) of positive integers, an S-packing coloring of a graph G is a partition of the vertex set of G into k subsets{V1, V2, . . . , Vk} such that for each 1 ≤ i ≤ k, the distance between any two dis-tinct vertices u and v in Vi is at least si + 1. Our focus is centered on an intriguing conjecture proposed by Brešar et al., which states that packing chromatic number of the subdivision of any subcubic graph is at most 5. Our desired aim is to provide a confirmation of this conjecture for specific classes of subcubic graphs, and to address the unresolved issues raised within this subject matter. An observation for Gastineau and Togni states that if a graph G is (1, 1, 2, 2)-packing colorable, then the chromatic number of its subdivision graph S(G) is at most 5, and hence it satisfies the conjecture. Depending on this observation, and in order to prove the correctness of the conjecture for the class of cubic Halin graphs, we studied its S-packing coloring aiming to prove that it admits a (1, 1, 2, 2)- packing coloring. We proved that a cubic Halin graph is (1, 1, 2, 3)-packing colorable, then it is (1, 1, 2, 2)-packing colorable, and so we confirm the conjecture for this class. Moreover, Gastineau and Togni, after proving that every subcubic graph is (1, 2, 2, 2, 2, 2, 2)-packing colorbale, have posed an open problem on whether every subcubic graph is (1, 2, 2, 2, 2, 2)-packing colorable. We answer this question in affirmative in the particular class we worked on; we proved that cubic Halin graphs are (1, 2, 2, 2, 2, 2)-packing colorable

Abstract:
Bien que beaucoup de problèmes à résoudre dans un système de bases de données objet sont similaires à ceux existant dans un système relationnel, il y a aussi plusieurs problèmes qui sont uniques. En particulier, chaque objet a un identifiant unique (oid) qui peut être utilisé pour référencer un autre objet. Cela fournit l'aspect navigation de sgbdo. Une requête objet peut inclure une expression de chemin pour la traversée de plusieurs collections. Le problème d'optimiser l'expression de chemin ressemble à celui du traitement de la jointure en système relationnel, mais il est plus complexe dans les systèmes objets. Cette thèse propose quatre approches pour aborder ce problème. D'abord, elle compare les performances de différentes méthodes de traversée de chemin, y compris la navigation, la jointure en avant ou en arrière, et la jointure par valeur, etc. , dans différentes situations. Elle propose une règle heuristique pour choisir éventuellement un opérateur naire. La deuxième partie de la thèse propose deux nouveaux opérateurs algébriques de navigation pour évaluer des expressions de chemin linéaires et en étoiles. Différentes stratégies de navigation sont étudiées. La troisième partie de la thèse introduit une adaptation de l'algorithme génétique pour explorer l'espace de recherche de plan d'exécution génère par une expression de chemin. Différents algorithmes combinatoires sont comparés. Enfin, cette thèse propose une méthode pour calibrer les bases de données objets en utilisant un modèle de coût générique, en particulier pour déduire le coût des traversées de chemins

Abstract:
Notre thèse analyse conjointement le travail des journalistes de presse et des formes de publicité au Liban après 1990. Elle repose sur une enquête ethnographique, associant entretiens et observation participante menée entre juin 2003 et juillet 2007 auprès de soixante journalistes travaillant dans les sections politiques, locales et culturelles d'An Nahar, As Safir et L'Orient-Le Jour. Nous identifions des moments clés de la structuration du groupe professionnel et proposons une étude pragmatique des institutions (universités, syndicats, journaux) en charge de la définition de la profession. Resserant le cadre d'analyse, nous examinons une variété d'engagements politiques et confessionnels manifestés par les journalistes dans leur travail quotidien et qui consuisent à la formation de liens spécifiques avec les publics. Nous nous intéressons également aux formes de critiques et d'argumentation propres à l'espace journalistique libanaisThis research focuses on the work of press journalists and forms of publicity in Lebanon, after 1990. I first identifty key moments of the building of the profession and I analyze, with pragmatic tools, the work of institutions (universities, trade-unions and newspapers) in charge of the definition of the profession. I analyse secondly a variety of political and confessional commitments of the journalists in their everyday work and wich produce specific types of links with the public. Last, I study forms of critics and argumentation specific to the Lebanese journalistic space

Abstract:
Ce mémoire vise à démontrer, à travers l’analyse des sources du renseignement militaire russe, que vers la fin du XIXᵉ siècle, la construction du chemin de fer de Bagdad par les Allemands conduit à la reconfiguration du Grand Jeu. L’intervalle historique qui s’étend de 1878 à 1914 représente la période de l’avènement de l’Allemagne en tant que nouvel acteur de la rivalité qui opposait jusqu’ici les Russes et les Britanniques en Asie centrale. L’immixtion allemande en Asie Mineure amène à l’internationalisation de la scène moyen-orientale par la construction de la voie ferrée qui, devant relier le Bosphore au golfe Persique, menaçait directement la domination britannique sur la route des Indes et modifiait la conception antérieure du Grand Jeu. En analysant quelques centaines de pages de documents provenant des sources du renseignement militaire russe, à savoir des dépêches, des comptes rendus et des rapports des agents militaires (voennye agenty) ainsi que des notices des représentants diplomatiques russes au Moyen-Orient, nous avons discerné les positions prises par les grandes puissances dans l’entreprise de Bagdad, tout en mettant de l’avant le conflit d’intérêts qui accompagnait l’établissement du tracé du futur chemin de fer. En menaçant la sécurité de l’Inde britannique d’un côté, et en contribuant au renforcement de l’armée turque à la frontière caucasienne de l’autre, le projet allemand de la Bagdadbahn fait avancer la Marche vers l’Est en inaugurant la Weltpolitik germanique.

Abstract:
Modern multimedia (MM) communication systems aim to provide new services such as multicast (MC) communication. But the rising of new very different MM capable devices and the growing number of clients drive to new requirements for mechanisms and protocols. In a MM communication, there are some flows that have constraints different from others and the required QoS for each flow is not the same. Furthermore, in MC communications, all the users do not want or are not able to receive the same QoS. These constraints imply that new communication mechanisms have to take into account the user requirements in order to provide an ad hoc service to each user and to avoid wasting the network resources. This dissertation proposes a new differentiated QoS multicast architecture, based on client/server proxies, called M-FPTP, which relays many MC LANs by single partially reliable links. This architecture provides a different QoS to each LAN depending on the users requirements. For doing so, it is also provided a network model called Hierarchized Graph (HG) which represents at the same time the network performances and the users QoS constraints. Nevertheless, the application of standard tree creation methods on an HG can lead to source overloading problems. It is then proposed a new algorithm called Degree-Bounded Shortest-Path-Tree (DgB-SPT) which solves this problem. However, the deployment of such a service needs a new protocol in order to collect users requirements and correctly deploy the proxies. This protocol is called Simple Session Protocol for QoS MC (SSP-QoM). The proposed solutions have been modeled, verified, validated and tested by using UML 2.0 and TAU G2 CASE tool.

Abstract:
Très détruit et très restauré, le théâtre antique de Vaison-la-Romaine demeure néanmoins un objet d’étude précieux, livrant d’importantes informations sur son architecture. Parmi les parties basses de l’édifice, souvent taillées dans le substrat rocheux, les aditus maximi sont relativement bien conservés, permettant d’en décrire la disposition, les dimensions, les accès, et d’en restituer les superstructures. Leur observation permet en outre, au sein du plan symétrique du théâtre, de distinguer l’aditus oriental, sommairement traité et destiné à un usage charretier fonctionnel, de l’aditus occidental, davantage soigné et réservé à un usage piétonnier. Le plan de la ville antique explique pour partie cette distinction, montrant une nette dissymétrie dans les accès au théâtre : l’un prestigieux, à l’ouest, empruntant une rue reliant l’édifice de spectacle au forum, l’autre plus ordinaire, à l’est, formé d’un simple chemin débouchant sur une route d’accès à l’agglomération antique.

Abstract:
AbstractMemory safety bugs continue to be a major source of security vulnerabilities in our critical infrastructure. The CHERI project has proposed extending conventional architectures with hardware-supported capabilities to enable fine-grained memory protection and scalable compartmentalisation, allowing historically memory-unsafe C and C++ to be adapted to deterministically mitigate large classes of vulnerabilities, while requiring only minor changes to existing system software sources. Arm is currently designing and building Morello, a CHERI-enabled prototype architecture, processor, SoC, and board, extending the high-performance Neoverse N1, to enable industrial evaluation of CHERI and pave the way for potential mass-market adoption. However, for such a major new security-oriented architecture feature, it is important to establish high confidence that it does provide the intended protections, and that cannot be done with conventional engineering techniques.In this paper we put the Morello architecture on a solid mathematical footing from the outset. We define the fundamental security property that Morello aims to provide, reachable capability monotonicity, and prove that the architecture definition satisfies it. This proof is mechanised in Isabelle/HOL, and applies to a translation of the official Arm specification of the Morello instruction-set architecture (ISA) into Isabelle. The main challenge is handling the complexity and scale of a production architecture: 62,000 lines of specification, translated to 210,000 lines of Isabelle. We do so by factoring the proof via a narrow abstraction capturing essential properties of arbitrary CHERI ISAs, expressed above a monadic intra-instruction semantics. We also develop a model-based test generator, which generates instruction-sequence tests that give good specification coverage, used in early testing of the Morello implementation and in Morello QEMU development, and we use Arm’s internal test suite to validate our model.This gives us machine-checked mathematical proofs of whole-ISA security properties of a full-scale industry architecture, at design-time. To the best of our knowledge, this is the first demonstration that that is feasible, and it significantly increases confidence in Morello.

Abstract:
Abstract Nuclear magnetic resonance (NMR) spectroscopy is based on the fact that atomic nuclei oriented by a strong magnetic field (2-14 Tesla) absorb radiation at characteristic frequencies (typically a few hundred megahertz, in the radiofrequency part of the spectrum). The usefulness of NMR to the chemist and biologist results largely from the fact that nuclei of the same element in different environments give rise to distinct spectral lines. This makes it possible to observe signals from individual atoms even in complex biological macromolecules in solution. The parameters that can be measured from the resulting spectra can be interpreted in terms of molecular structure, conformation, and dynamics.

Abstract:
The fact that Artificial Intelligence (AI) based algorithms exhibit a high performance on image classification tasks has been shown many times. Still, certain issues exist with the application of machine learning (ML) artificial neural network (ANN) algorithms. The best known is the need for a large amount of statistically varied data, which can be addressed with expanded collection or data augmentation. Other issues are also present. Convolutional neural networks (CNNs) show extremely high performance on image-shaped data. Despite their performance, CNNs exhibit a large issue which is the sensitivity to image orientation. Previous research shows that varying the orientation of images may greatly lower the performance of the trained CNN. This is especially problematic in certain applications, such as X-ray radiography, an example of which is presented here. Previous research shows that the performance of CNNs is higher when used on images in a single orientation (left or right), as opposed to the combination of both. This means that the data needs to be differentiated before it enters the classification model. In this paper, the CNN-based model for differentiation between left and right-oriented images is presented. Multiple CNNs are trained and tested, with the highest performing being the VGG16 architecture which achieved an Accuracy of 0.99 (+/- 0.01), and an AUC of 0.98 (+/- 0.01). These results show that CNNs can be used to address the issue of orientation sensitivity by splitting the data in advance of being used in classification models.

In ASME 2023 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2023. http://dx.doi.org/10.1115/imece2023-112806.
Abstract:
Abstract The real-time assessment and prognostication of food texture during mastication are paramount for comprehending and emulating the chewing process, bearing significant ramifications for the food industry. This study unveils a deep learning-oriented recognition framework utilizing Mask R-CNN to analyze food texture throughout the mastication process. We create an extensive food bolus image compendium and train a deep learning model proficient in texture discrimination and processing parameter estimation. A vision system, incorporating an Intel RealSense D435i camera, is harnessed to capture high-resolution images of the food bolus. The dataset encompasses images of masticated peanut samples, with the number of chews varying from 1 to 12 cycles. Although the model’s predictions occasionally diverge from the actual data points, with a maximum discrepancy of ±2 chewing instances chews except for predicting peanuts chewed 11 cycles, the proposed system lays the groundwork for real-time evaluation and prediction of food texture during mastication. Future inquiries could concentrate on ameliorating the model’s precision, broadening its applicability to diverse food categories, and refining the training dataset. This investigation holds the potential to influence the advancement of delectable and nourishing food products, bestowing benefits upon both the food industry and consumers.

Abstract:
Work on gel propulsion began in Germany in 1999. The German Gel Propulsion Technology (GGPT) Program started in 2001 from a white sheet of paper, proposed by the DLR Institute of Space Propulsion, Bayern-Chemie (BC), and the Fraunhofer Institute of Chemical Technology. Aim of the first phase was to develop the technology needed to build a rocket motor burning gelled propellants and to demonstrate its operability by a free flight within significantly less than a decade. The research and development activities were guided by a suitable principal concept for a gelled propellant rocket motor (GRM). Based on theoretical considerations (regarding functional aspects) and experimental pre-tests (propellant development, gelation, rheology, spraying, ignition, and combustion), a motor concept was pre-selected and the motor developed. The identified requirements were proven in December 2009 by two successful demonstration flights. The achieved know-how from basic research and technology (R+T) development has been consolidated in an application-oriented way on component level up to motor development. Within this scope, also, the goal of an effective control of the thrust by throttling the propellant mass flow rate (PMFR) while maintaining an optimum combustion chamber (CC) pressure could be achieved. This publication describes briefly several major advances in the development of the gel propulsion technology in Germany from rheology to combustor development to the thrust and pressure controller of a GRM.

Abstract:
The heat transfer principle of power maximization in power plants with heat transfer irreversibilities was cleverly extended by Bejan [1] to fluid flow, by obtaining that the energy conversion efficiency at maximum power is ηmax = 1/2(1 − P2/P1). This result is analog to the efficiency at maximum power for power plants, ηmax = 1 − (T2/T1)1/2 which was deduced by Curzon and Ahlborn [2]. In this paper, the analysis to obtain maximum power output delivered from a piston between two pressure reservoir across linear flow resistance is generalized by considering the piston cylinder friction, by obtaining relations of maximum power output and optimal speed of the piston in terms of first law efficiency. Expressions to relate the power output, cross sectional area of the chamber and first law efficiency, were deduced in order to evaluate the influence of the overall size constraints and fluid regime in the performance of the piston cylinder system. Flow in circular ducts and developed laminar flow between parallel plates, are considered to demonstrate that when two pressure reservoirs oriented in counterflow, with different and arbitrary cross sectional area, must have the same area in order to maximize the power output of the system. These results introduce some modifications to the results obtained by Bejan [1] and Chen [3]. This paper extends the Bejan and Chen’s work by estimating under turbulent regime the lost available work rate associated with the degree of irreversibilities caused by the flow resistances of the system. This analysis is equivalent to evaluate the irreversibilities in an endoirreversible Carnot heat engine model caused by the heat resistance loss between the engine and its surrounding heat reservoirs. This paper concludes with an application to illustrate the practical applications by estimating the lost available work of an actual steady-flow turbine and the layout pipes upstream and downstream of the same device.

Based upon our previous study, we do know that in China living habits and local climate mainly influence the shape of residential buildings and apartment patterns, but we do not know whether the pattern of residential plots determined by FAR and sunshine hours are suitable for wind environment related to residential environmental quality. Therefore, it is very significant to evaluate wind environment within residential plots based on the apartment pattern controlled by various building codes. Our study focuses on the pattern of Slab apartments in Nanjing, which are mainly used in China, and selects 40 residential slices with different plot shapes, plot FAR, building heights and sizes. Based upon MATLAB, we have got all geometrical data between buildings among these slices to identify the spatial pattern character of each residential plot. Through evaluating wind environment of these slices by simulation we can obtain wind speed, pressure and age of air and choose the pattern of age of air as the main evaluation factor of wind performance. Correlation analysis will be made between the apartment patterns and pattern of age of air, by doing so, each typical space between buildings will be evaluated. Our study will reveal the relevance of apartment pattern and wind environment, which can be used to support and improve design in the future. References（95 words） Oke. T.

However, the spatial configurations which could stimulate the transformation around the neighbourhoods of the station have not been clearly identified. It could be argued that the implementation of transport systems and the creation of new stations would enhance the mobility of the transport network and the accessibility around the station’s vicinity. Furthermore, the dynamics of pedestrian flow, generated by the new transport system might transform the social, cultural and economic activities around the stations. Therefore, the aims of this study are to analyse how the spatial configuration and the urban formation are affected by the implementation of stations and understand how the new stations emerge in the urban form. The Jubilee Line Extension (JLE) in East London, which started to operate in 2000, plays an essential role in connecting Central London with the recently developed financial district in the east. This study focuses on two stations located along the JLE, Bermondsey and West Ham, which have different topological and demographic characteristics. To determine whether the stations integrate cohesively with the urban environment, this study applies Space Syntax methods of spatial network analysis to evaluate the spatial characteristics and compares with GIS data of the house prices and land use distribution before and after the JLE. The results demonstrate a strong correlation between pedestrian movement and the distribution of residential and commercial activities within the street network structure. The study also reveals the strength and weakness of the stations, which are embedded within urban structures and suggests urban regeneration strategies through improving the accessibility and public space design.

Abstract:
The traditional Chinese aerobic fitness exercise tai chi, is a form of low to moderate intensity physical activity. Tai chi is a good example of both therapeutic exercise and a form of preparation for gentle hand-to-hand combat (especially as safe self-defence, also from the perspective of a potential aggressor) . In Chinese society, these forms of exercise are the primary means of preventive health, active lifestyle and, in a sense, conventional physiotherapy or even rehabilitation. Many schools of tai chi based on the same theoretical principles of exercise are still emerging in China. There are currently six main schools of tai chi and the mainstream is based on the styles; Chen, Yang, Sun, Hao, Wu and He. As a result of evolutionary, practice-based changes linked to traditional oriental medicine, the ai chi method has been popularised. Its core element is part of rehabilitation in water as a 'physical-mental' treatment. Combining the advantages of tai chi and hydropathy, ai tai chi has complementary advantages in terms of sensory stimulation (such as the ability to maintain balance, sense of movement, development of strength, proprioception etc.) and mental development resulting from the valuable practice of eastern hand-to-hand combat, which is generally recognised as kung fu (alternatively wu shu).Similar modifications of these systems of hand-to-hand combat and healing exercises are part of the methodological concept of INNOAGON (an acronym for innovative agonology). Its basic method is a complementary approach, with the main aim of strengthening all dimensions of health and survival from the micro to the macro scale. For many decades tai chi has been gaining popularity around the world, but has moved significantly away from its roots. Today, tai chi exercises seem to have lost the sense of martial training and are rather seen as three strands parallel to each other: sport, health and spiritual (i.e. related to mental health). It is precisely the philosophy of health characteristic of Chinese culture combined with the various styles of traditional kung-fu hand-to-hand combat that is a very important alternative to the pathologies of neo-gladiatorism. It comes close to fulfilling the social mission of INNOAGON, as does Japanese budo. These systems, in a sense, refer to the Greek philosophy of kalos kagatos. The methodological potential of INNOAGON makes intercultural dialogue over time (from the past, through the present towards the future), supported by a repeatedly verified practice with great health and personal security values, an important way of balancing the negative effects of the increasingly strong human coupling with the attractions of modern digital technology.

Abstract:
1 BackgroundBased on the current structural shortage of labor force and serious shortage of caregivers in China's elderly and medical services [1], the future demand for elderly care services for the elderly population is also increasingly strong [2]. At present, the proportion of Chinese elderly people living in elderly care institutions is 0.73%, which reflects that there are still some obstacles to the general acceptance of elderly care institutions by Chinese elderly people. Combined with the theory of environmental psychology, it can be seen that the environment can have an impact on behavior, psychology and other aspects, so the scientific shaping of space is inextricably linked to the enhancement of the user's spatial acceptance. Based on this, this study discusses the development history, development status and future development trend of nursing home design in China, and explores the innovative development path of nursing home design in the future. It aims to improve the acceptance and willingness to use nursing homes by the elderly and their families through optimization at the design level, so as to alleviate the current aging problem in China and the world.2 MethodDesign form language, is a kind of abstract language that can cover the design concept, design strategy, is a logical combination of structure, color, material and other figurative language in design. The change of design form language is often closely related to the change of user needs, the development of the industry now, etc. Citespace can present the structure of knowledge, the situation of information in the form of graphical distribution [3], and combined with the resulting graphs to analyze the disciplinary structure of the field of study related to the discipline structure, the hot frontier and other laws [4]. In view of the fact that the keyword maps that can be directly generated by importing literature data in Citespace cannot accurately represent the design form language explored in this study, this study organizes the design form language of each piece of literature in the valid title data for the titles, keywords, and abstracts of the 253 pieces of literature in the CNKI database, respectively.3 ResultThis study combines the data processing results of the design form language to produce three results related to the development of nursing home design in China. First, the development history of nursing home design in China is divided into three stages: the "starting period", the "high speed development period" and the "innovation enlightenment period", and there is still much room for development. Secondly, from the current development status of Chinese nursing home design, the concentration of current research is high, which also proves that the innovation of Chinese nursing home design is low at this stage. In addition, the research hotspots are mainly "people-oriented" and "integration of medical and nursing care", which reflects the current Chinese nursing home design's emphasis on the physiological and psychological needs of the elderly, and conforms to the current Chinese government's guidelines for nursing homes. Thirdly, "multi-dimensional consideration of user needs", "optimization of nursing home living mode through spatial design", and "exploration of cutting-edge fields" are proposed, The four suggestions on the direction of future development of nursing home design in China are "multi-dimensional consideration of users' needs", "optimization of living mode through spatial design", "exploration of frontier fields", and "in-depth combination of theory and practice".4 ConclusionThis study applies Citespace to analyze the literature about design form language visualization mapping in the field of Chinese nursing home design in the past 15 years, and according to the changing law of design form language, we have launched a study on the development history, development status, and future development trend of China's nursing home design, and obtained four directions of the future of China's nursing home design that are worth developing and studying in depth, which provides a directional guideline for the research of China's nursing home design.References[1] Zuo Meiyun.

In 15th International Conference on Applied Human Factors and Ergonomics (AHFE 2024). AHFE International, 2024. http://dx.doi.org/10.54941/ahfe1005308.
Abstract:
In industrial countries, caring for the elderly in geriatric nursing homes is rapidly growing. Caregivers face intensive demands and often suffer from high workloads and frequent work interruptions. Not only in patients but also in geriatric nurses, slips, trips, and falls (STF) are frequent. We expect work interruptions to increase attentional failure, and attentional failure to increase the risk of STF (hypothesis 1). Moreover, we expect caregiver’s job tenure to moderate the indirect effect of work interruptions via attention failure on STF. The indirect mediation path should to be stronger in caregivers with less job tenure compared to caregivers who are rather tenured (hypothesis 2). With increasing job experience task regulation in many tasks has become automatic and less resource consuming and therefore more experienced caregivers attention capacity is less likely to be overcharged by work interruptions. Purpose: The current study tests a mediation model with attentional failure as a mediator between work interruptions and STF and job tenure as a potential moderator of such mediation. The sample comprised 45 geriatric nurses. Methods: All measures were self-report. Interruptions of work were assessed by a shortened version of the Instrument for Stress- Oriented Task Analysis (Semmer et al., 1995). Attention failure at work was assessed with the subscale of attention failure from the Workplace Cognitive Failure Scale (Wallace & Chen, 2005) in the German-validated translation). STFs at work were assessed with a scale from Elfering et al. (2013). Job tenure was assessed with a single item. The moderated mediation model was based on OLS regression analyses. The mediation tests were done using the PROCESS SPSS macro tool (Hayes, 2018). Results: The test of the mediation model showed significant path coefficients for the path between task interruptions and attention failure and the path between attention failure and STF. Variance explanation in the prediction of attentional failure (33% variance explanation, p = 002) and prediction of STF (27% variance explained, p = .003) was satisfactory. Moreover, the strength of the indirect path (path a * path b) was significant for the mean of job tenure (B = 0.10, SE = .06, CI = 0.02 to 0.21), but higher with low job tenure and smaller with high job tenure. The indirect path for those participants with low job tenure was stronger (PR 16% or 1 year of job tenure: B = 0.16, SE = .09, CI = 0.04 to 0.32). For those participants with the highest job tenure (PR 84% or 5 years of job tenure), the indirect path was smaller and not significant anymore (B = 0.04, SE = .07, CI = -0.04 to 0.18). Hence, the strength of mediation did depend on job tenure, but the test of moderation failed to reach statistical significance, although the interaction of job tenure * task interruptions explained 4% of the variation in attentional failure (p = .085). In sum, the mediation model (hypothesis 1) was confirmed while the moderated mediation (hypothesis 2) was rejected but data showed a tendency that pointed in the expected direction. Conclusions: The study needs replication in a larger sample and preliminary evidence should be consolidated by use of a longitudinal and/or experimental design. The preliminary evidence suggests that interruptions should be targeted not only in the prevention of work stress and efforts to increase patient safety but also in the prevention of STF in geriatric nurses. Training should address nurses, managers, and residents on how to reduce interruptions and how to cope with task interruptions.

Abstract:
Le programme Covid-19 Responses for Equity (CORE) est une initiative sur trois ans financée par le Centre de recherches pour le développement international (CRDI) du Canada, qui a rassemblé 20 projets issus des pays du Sud afin de comprendre les impacts socio-économiques de la pandémie de Covid-19, d’améliorer les réponses existantes et d’élaborer de meilleures options politiques pour favoriser la relance. Les recherches ont porté sur 42 pays d’Afrique, d’Asie, d’Amérique latine et du Moyen-Orient afin de comprendre comment la pandémie a affecté les régions et les personnes les plus vulnérables en aggravant les fragilités existantes. Les projets de recherche ont couvert un large éventail de thèmes, notamment les politiques macroéconomiques de soutien et de redressement, l’appui aux activités économiques essentielles et la protection des entreprises informelles, des petits producteurs et des femmes au travail, ainsi que la promotion d’une gouvernance démocratique pour renforcer la responsabilité, l’inclusion sociale et l’engagement civique. L’Institute of Development Studies (IDS) a apporté aux partenaires de recherche du programme CORE un appui à l’application des connaissances afin de maximiser l’apprentissage généré dans l’ensemble du portefeuille de recherche et d’approfondir l’engagement auprès des gouvernements, de la société civile et de la communauté scientifique. Dans le cadre de ce soutien, l’équipe d’application des connaissances de l’IDS a travaillé avec les équipes de projet du programme CORE pour reconstruire et réfléchir à leurs chemins d’impact afin de faciliter l’échange de connaissances Sud-Sud sur des stratégies efficaces pour l’impact de la recherche et de partager l’apprentissage sur la façon dont la cohorte du programme CORE a influencé les politiques et produit des changements. Ce rapport présente une vue d’ensemble de ces chemins d’impact et des enseignements tirés d’une sélection de projets choisis pour représenter la diversité des approches visant à mobiliser les décideurs politiques, la société civile et les médias afin de générer et de partager des données probantes des effets de la pandémie sur différents groupes vulnérables.
