The Conflict Between Free Access to Information and the use of Filtering Techniques in Light of the Yahoo Case

The exponential growth and explosion of Information on the Internet has given rise to several questions of socio-economic, political and legal nature, especially as regard to the issue of free access to information and possible limitations to this free use. Since the Internet is a global operating network exceeding therefore national territories, the problem of universal jurisdiction rises. The introduction of filtering techniques has been introduced to deal with this problem. However the use of filtering techniques poses several problems as well and can clearly have a chilling effect on free speech as well.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej nauk

Fluid-Structure Interaction by the Spectral Element Method

Viscous fluid-structure interaction is treated with an arbitrary Lagrangian- Eulerian formulation. The spatial discretization is performed by the spectral element method for the fluid part where the Navier-Stokes equations are integrated and in the solid part where transient linear elasticity is described by the Navier equations. Time marching algorithms are second-order accurate in time in both the fluid and the solid. The algorithm is applied to the flow in a plane channel partially obstructed by a solid component able to move under the action of the fluid flo

Publication, Testing and Visualization with EFES : A tool for all stages of the EpiDoc XML editing process

EpiDoc is a set of recommendations, schema and other tools for the encoding of ancient texts, especially inscriptions and papyri, in TEI XML, that is now used by upwards of a hundred projects around the world, and large numbers of scholars seek training in EpiDoc encoding every year. The EpiDoc Front-End Services tool (EFES) was designed to fill the important need for a publication solution for researchers and editors who have produced EpiDoc encoded texts but do not have access to digital humanities support or a well-funded IT service to produce a publication for them. This paper will discuss the use of EFES not only for final publication, but as a tool in the editing and publication workflow, by editors of inscriptions, papyri and similar texts including those on coins and seals. The edition visualisations, indexes and search interface produced by EFES are able to serve as part of the validation, correction and research apparatus for the author of an epigraphic corpus, iteratively improving the editions long before final publication. As we will argue, this research process is a key component of epigraphic and papyrological editing practice, and studying these needs will help us to further enhance the effectiveness of EFES as a tool. To this end we also plan to add three major functionalities to the EFES toolbox: (1) date visualisation and filter—building on the existing “date slider,” and inspired by partner projects such as Pelagios and Godot; (2) geographic visualization features, again building on Pelagios code, allowing the display of locations within a corpus or from a specific set of search results in a map; (3) export of information and metadata from the corpus as Linked Open Data, following the recommendations of projects such as the Linked Places format, SNAP, Chronontology and Epigraphy.info, to enable the semantic sharing of data within and beyond the field of classical and historical editions. Finally, we will discuss the kinds of collaboration that will be required to bring about desired enhancements to the EFES toolset, especially in this age of research-focussed, short-term funding. Embedding essential infrastructure work of this kind in research applications for specific research and publication projects will almost certainly need to be part of the solution.Peer reviewe

PANTR: A proximal algorithm with trust-region updates for nonconvex constrained optimization

This work presents PANTR, an efficient solver for nonconvex constrained optimization problems, that is well-suited as an inner solver for an augmented Lagrangian method. The proposed scheme combines forward-backward iterations with solutions to trust-region subproblems: the former ensures global convergence, whereas the latter enables fast update directions. We discuss how the algorithm is able to exploit exact Hessian information of the smooth objective term through a linear Newton approximation, while benefiting from the structure of box-constraints or l1-regularization. An open-source C++ implementation of PANTR is made available as part of the NLP solver library ALPAQA. Finally, the effectiveness of the proposed method is demonstrated in nonlinear model predictive control applications.Comment: Accepted for publication in IEEE Control Systems Letter

The Challenge of a Global Internet Regulation for Global Electronic Commerce

The Internet is a global operating network exceeding therefore national territories. The territoriality principle on which regulation in general is based conflicts consequently with the international character of the Internet. In dealing with global electronic commerce the question has often been raised whether there is a need for a so-called Lex Internet modeled on the Lex Mercatoria to deal with the growing conflicts, and whether this could be realized in practice. However critics has also been raised concerning this concept. What becomes ultimately clear from this concise overview is the perception that states are forced to work more closely together.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 zostało dofinansowane ze środków MNiSW w ramach działalności upowszechniającej nauk

Interaction fluide-structure par la méthode des éléments spectraux

We elaborate in this thesis the numerical simulation of the fluid-structure interaction by the spectral element method. To this end we consider the Navier-Stokes equations for a viscous Newtonian incompressible fluid with an elastic solid the movement of which being described by the equations of the dynamics. The arbitrary Lagrangian Eulerian (ALE) formulation is introduced in the fluid governing equations to deal with the structure movement that is described in Lagrangian representation. The geometrical motion in each domain is built up by the mesh deformation. The space-time discretization of the full mathematical model rests upon the spectral element method. The solid is discretized in the space of polynomials of degree N, PN, while the fluid uses the PN - PN-2 approach. The efficiency of the ALE formulation is tested and validated through various applications. The full algorithm is based on a particular case of the staggered method. The simplified case of a solid immersed in a plane channel closes the thesis. It is then possible to draw the conclusions about the pros and cons of the proposed methodology
