Det ulmer under overflaten. Agathe Backer Grøndahl (1847-1907). Genus, sjanger og norskhet
No full textAbstract Ph.D. dissertation at Göteborg University, Sweden, 2008 Author: Camilla Hambro Title: Det ulmer under overflaten. Agathe Backer Grøndahl (1847–1907), genus, sjanger og norskhet English title: What smoulders beneath the surface. Agathe Backer Grøndahl (1847–1907), gender, genre and Norwegianness Language: Norwegian, with an English summary Department: Department of Culture, Aesthetics and Media Series: Skrifter från musikvetenskap, Göteborgs universitet, nr 91, 2008 ISSN 1654-6261 ISBN 978-91-85974-07-8 My dissertation is a problem oriented one. The composer pianist Agathe Backer Grøndahl (1847–1907) has always been a self-evident figure in chapters of Norwegian music history books that cover music, musicians and composers in "Grieg’s shadow". Extensive historical source materials (reception materials connected to Backer Grøndahl’s concerts and compositions; her letters, notebooks, workbooks and sketches) form the basis of the study. The problems studied are what kind of expectations are connected to three intertwined core concepts connected to Backer Grøndahl, namely: "femininity", "genre", and "Norwegianness" (the folk-influenced Norwegian tradition). Musical and material, as well as institutional, sociological and economical, ”Agathe Backer Grøndahl” discourses are examined. The arenas where the three core concepts and discourses unfold, sound, develop, are moulded and understood, are threefold: •Musical culture with which the pianist composer and her compositions interacted from 1866–1903. •Presentations of her in monographs and music history books. •Various attempts to revise this kind of music historiography. The musical analysis starts out from reception materials connected to her performances of her own works and tries to trace the critics’ descriptions in the scores. The works analyzed are: One of her two orchestral compositions, Andante quasi allegretto for piano and orchestra (1869) in sonata form. (I rediscovered this "lost" work in the National Library in Oslo.) The song "To the queen of my heart" (Op. 1/3, 1870), the descriptively titled lyrical piece Wood Nymph’s Dance (1887), the feminist cantata Nytaarsgry (1901) performed at the Scandinavian Women’s Convention 1902 and the singable and (in)famous song "Eventide" Op. 42/7 1899). Performed compositions become performative via the reception materials, hers, the listeners’ and amateur performers "producerly texts" connected to them
Learning State Machines to Monitor and Detect Anomalies on a Kubernetes Cluster
No full textThese days more companies are shifting towards using cloud environments to provide their services to their client. While it is easy to set up a cloud environment, it is equally important to monitor the system's runtime behaviour and identify anomalous behaviours that occur during its operation. In recent years, the utilisation of Recurrent Neural Networks (RNNs) and Deep Neural Networks (DNNs) to detect anomalies that might occur during runtime has been a trending approach. However, it is unclear how to explain the decisions made by these networks and how these networks should be interpreted to understand the runtime behaviour that they model. On the contrary, state machine models provide an easier manner to interpret and understand the behaviour that they model. In this work, we propose an approach that learns state machine models to model the runtime behaviour of a cloud environment that runs multiple microservice applications. To the best of our knowledge, this is the first work that tries to apply state machine models to microservice architectures. The state machine model is used to detect the different types of attacks that we launch on the cloud environment. From our experiment results, our approach can detect the attacks very well, achieving a balanced accuracy of 99.2% and a F1 score of 0.982. Cyber Securit
Nouveaux algorithmes de détection d'anomalies et de classification pour les réseaux IP et mobile
No full textCes dernières années ont été marquées par une nette augmentation de la fréquence et de la diversité des attaques réseau, qui apparaissent toujours plus sophistiquées et conçues pour être indétectables. En parallèle, des techniques sont développées pour les détecter et prendre des contre-mesures rapidement. Récemment, l’essor des techniques statistiques et d’apprentissage machine ("machine learning") ont permis un développement rapide de techniques innovantes visant à détecter de telles attaques. Ces techniques ont des applications dans de nombreux domaines qui gagneraient à être davantage automatisés. Dans le domaine des réseaux, elles s’appliquent par exemple au routage et à la classifcation de trafic et à la sécurité des réseaux. Cette thèse propose de nouveaux algorithmes de détection d’anomalies et de classification appliqués aux réseaux IP et mobiles. Au niveau IP, celle-ci présente une solution Split-and-Merge qui détecte des botnets qui se propagent lentement sur Internet en exploitant des vulnérabilités émergentes. Cette méthode analyse l’évolution à long-terme de l’usage des ports applicatifs. Ensuite, celle-ci aborde la détection d’hôtes infectés par un botnet, cette fois en utilisant des techniques de classification au niveau de l’hôte, dans une solution nommée BotFP. Enfin, cette thèse présente notre algorithme ASTECH qui permet la détection d’anomalies brutes dans les séries temporelles dans les réseaux mobiles, les regroupe en enveloppes convexes spatio-temporelles, et finalement induit plusieurs classes d’événements.Last years have witnessed an increase in the diversity and frequency of network attacks, that appear more sophisticated than ever and devised to be undetectable. At the same time, customized techniques have been designed to detect them and to take rapid countermeasures. The recent surge in statistical and machine learning techniques largely contributed to provide novel and sophisticated techniques to allow the detection of such attacks. These techniques have multiple applications to enable automation in various fields. Within the networking area, they can serve traffic routing, traffic classification, and network security, to name a few. This thesis presents novel anomaly detection and classification techniques in IP and mobile networks. At IP level, it presents our solution Split-and-Merge which detects botnets slowly spreading on the Internet exploiting emerging vulnerabilities. This technique monitors the long-term evolutions of the usages of application ports. Then, our thesis tackles the detection of botnet’s infected hosts, this time at the host-level, using classification techniques, in our solution BotFP. Finally, it presents our ASTECH (for Anomaly SpatioTEmporal Convex Hull) methodology for group anomaly detection in mobile networks based on mobile app usages

Saint-Dizier-la-Tour – Église Saint-Didier
No full textSaint-Dizier-la-Tour est une commune de la Creuse, à une vingtaine de kilomètres à l’est de Guéret. Elle est constituée de deux anciens hameaux, la Tour-d’Austrille et Saint-Dizier réunis en 1848. L’église Saint-Didier et Saint-Blaise est localisée à l’ouest des habitations principales de Saint-Dizier. En 2004, cette dernière fait l’objet d’une inscription sur la liste des Monuments Historiques suite à la découverte d’un décor peint sur le mur intérieur sud du chœur, daté de 1650-1680. L’édif..
Formes de représentation, impératif d’actualité et enjeux de pouvoir sur les dispositifs numériques : L’exemple de J.K. Rowling et du site pottermore.com
No full textCet article interroge l’évolution des perceptions de la figure d’auteur par le public du fait de sa mise en scène sur les dispositifs numériques. Ces espaces, privilégiant la participation de chacun et les jeux collectifs, posent la question de l’autorité et des rapports de force se jouant au sein des textes y circulant. Le cas d’étude examiné ici, celui de la figure de J.K. Rowling sur le site internet pottermore.com, nous amène à définir l’architexte numérique comme un archi-auteur, déterminant les caractéristiques de la fonction-auteur, la posture de l’écrivain et son image dans le corps social. Nous interrogeons également la pertinence de la notion de « marque auteur » sur les dispositifs numériques, qui permettent à l’auteur d’être perçu comme une entité inaccessible chargée de l’autorité très spécifique des marques et des entreprises.This article questions the evolution of public perceptions of authors as a result of their presence on digital platforms. These environments, which privilege individual participation and collective games, question the notion of authority and of power relationships at play in the texts circulating there. The case study examined here, that of J.K. Rowling on the website pottermore.com, leads us to define the digital architext as an “archi-author,” determining the characteristics of the author-function, the stance of the author and her image in society. We also interrogate the relevance of considering the author as a “brand” on digital devices that allow the author to be perceived as an inaccessible entity laden with the very specific form of authority that is characteristic of brands and companies
"De kast, Huldren gjør med Kohalen" Om kjønn og andre musikalske identiteter i den norske komponisten Agathe Backer Grøndahls "Huldreslaat"
No full textThis article grew out of an interest in the intriguing Norwegian pianist, composer and piano teacher Agathe Backer Grøndahl (1847-1907), and her composition for piano, Huldreslaat. The work received its first performance with the composer herself at the piano in Kristiania 1887. By virtue of being music both in and as gender discourse, the score was in need of further fleshing-out, understanding and analysis. The author starts out from the assumption that gender roles were and are self organizing dynamic systems and that Grøndahl's gender roles worked towards goals that preserved her own interests. Ahistoric gender perspectives do not penetrate the ideological and social complexity in teh cirtics' understanding of femininity, which deviates substantially from the norms of the present. On the other hand close readings of them show us live experiences from the past. It seems like teh delineation of the work's title and Grøndahl's personal appearance were brought to bear on the inherent mednings of her piano playing, and the work in the performance process. Therefore, it is neither possible nor desirable to regard Huldreslaat in total isolation, since gender, Norwegian and international musical identities, are fundamentally intertwined and interdependent in the work, it's context, and reception materials
