The design and implementation of Neuma, a collaborative Digital Scores Library - Requirements, architecture, and models
2012
This paper presents the design and implementation of the Neuma platform, a digital library devoted to the preservation and dissemination of symbolic music content (scores). Neuma is open to musicologists, musicians, and music publishers. It consists of a repository dedicated to the storage of large collections of digital scores, where users/applications can upload their documents. It also proposes services to publish, annotate, query, transform, and analyze scores. The long-term goal of the project is to enable an open and collaborative space where musician communities will be able to share music in symbolic notation. The project is organized around the French IRPMF institute (BnF–CNRS) whi…

Thinking collaborative empowerment as a communication dispositive : the case of collaborative consumption’s online community services in a sustainabl…
2020
This thesis propounds an info-communicational approach of empowerment phenomenon in a market oriented context. In order to do so, we focus on discourses and communicational processes that refer to this very concept in “collaborative consumption” platforms’ framework. Massification of this type of services is accompanied by discourses emphasizing a socioecological “power” they would be carrying for consumers (as a more social and sustainable economy). We underline the gap between this utopia and the organizational reality of empowerment. First part of this thesis proposes to highlight this polysemic concept. The point is to problematize empowerment in tension between political communication …
Narzędzia kształtowania polskiej kultury muzycznej w dobie socrealizmu
2020
Realizm socjalistyczny, zwany prościej socrealizmem, to doktryna ideologiczno- estetyczna wspomagająca propagandę krajów komunistycznych. Jej korzenie sięgają Związku Radzieckiego, gdzie stanowiła jedyną słuszną metodę tworzenia sztuki od lat 30. XX wieku aż po kres mocarstwa, czyli rok 1991. Proces wprowadzania jedynej słusznej metody twórczej rozpoczęto w Polsce w 1949 roku. Władza organizowała zjazdy literatów, plastyków, architektów, filmowców, a także muzyków. Doktryna obowiązywała aż do 1956 roku (roku śmierci prezydenta Polski Ludowej Bolesława Bieruta), choć naciski zmalały wraz ze śmiercią Stalina w roku 1953. Władza komunistyczna dysponowała wieloma narzędziami mającymi skłonić ko…
Narrating Selves amid Library Shelves : Literary Mediation and Demediation in S. by J. J. Abrams and Doug Dorst
2019
This essay focuses on the various forms of narrating, mediating, and interpreting selves within and around a book object, the novel S. (2013) by J. J. Abrams and Doug Dorst. The novel S. is an experiment in producing a deceivingly realistic replica of a maltreated library book object, but its discursive practices also rely on familiar literary forms, harking back to epistolary commonplaces, as well as to marginalia, both ancient and modern. The book object S., which carries the text of the novel-within-a-novel, the readers' multilayered markings, and paraphernalia, forms an archive dramatizing the workings of memory, thought, and emotion. That archive also demonstrates how the characters co…

Automatic Quality Assessment of Cardiac MR Images with Motion Artefacts using Multi-task Learning and K-Space Motion Artefact Augmentation
2022
The movement of patients and respiratory motion during MRI acquisition produce image artefacts that reduce the image quality and its diagnostic value. Quality assessment of the images is essential to minimize segmentation errors and avoid wrong clinical decisions in the downstream tasks. In this paper, we propose automatic multi-task learning (MTL) based classification model to detect cardiac MR images with different levels of motion artefact. We also develop an automatic segmentation model that leverages k-space based motion artefact augmentation (MAA) and a novel compound loss that utilizes Dice loss with a polynomial version of cross-entropy loss (PolyLoss) to robustly segment cardiac st…
Renormalized solutions for degenerate elliptic–parabolic problems with nonlinear dynamical boundary conditions and L1-data
2008
Abstract We consider a degenerate elliptic–parabolic problem with nonlinear dynamical boundary conditions. Assuming L 1 -data, we prove existence and uniqueness in the framework of renormalized solutions. Particular instances of this problem appear in various phenomena with changes of phase like multiphase Stefan problems and in the weak formulation of the mathematical model of the so-called Hele–Shaw problem. Also, the problem with non-homogeneous Neumann boundary condition is included.
Algorithmic Complexity Vulnerability Analysis of a Stateful Firewall
2016
Algorithmic complexity vulnerabilities are an opportunity for an ad-versary to conduct a sophisticated kind of attack i.e. on network infrastructure services. Such attacks take advantage of worst case time or space complexity of algorithms implemented on devices in their software. In this paper we address potential risks introduced by such algorithmic behavior in computer networks in particular on a stateful firewall. First we introduce the idea and theoretical background for the attack. We then describe in full detail a successfully con-ducted attack which takes advantage of the worst case computational complexi-ty of O(n2) of a hash table data structure used to store active sessions. The …
