Just-In-Time Data Virtualization: Lightweight Data Management with ViDa

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Thomas Heinis, Manolis Karpathiotakis, Ioannis Alagiannis

As the size of data and its heterogeneity increase, traditional database system architecture becomes an obstacle to data analysis. Integrating and ingesting (loading) data into databases is quickly becoming a bottleneck in face of massive data as well as i ...

Towards A Unified Language for RDF Stream Query Processing

Jean Paul Calbimonte Perez

In recent years, several RDF Stream Processing (RSP) systems have emerged, which allow querying RDF streams using extensions of SPARQL that include operators to take into account the velocity of this data. These systems are heterogeneous in terms of syntax ...

Automating Ad hoc Data Representation Transformations

Martin Odersky, Vlad Ureche

To maximize run-time performance, programmers often specialize their code by hand, replacing library collections and containers by custom objects in which data is restructured for efficient access. However, changing the data representation is a tedious and ...

Towards the ultimate SM fit to close in on Higgs physics

Francesco Riva

With the discovery of the Higgs at the LHC, experiments have finally addressed all aspects of the Standard Model (SM). At this stage, it is important to understand which windows for beyond the SM (BSM) physics are still open, and which are instead tightly ...

On the eigenvalue decay of solutions to operator Lyapunov equations

Daniel Kressner

This paper is concerned with the eigenvalue decay of the solution to operator Lyapunov equations with right-hand sides of finite rank. We show that the kth (generalized) eigenvalue decays exponentially in root k, provided that the involved operator A gener ...

Etude de l’influence de la vitesse sur la quantité de Polychlorobiphényls (PCB) absorbée par un capteur passif dans le cadre de la recherche de sources de pollution

Adrien Schopfer

Lors de recherches de sources de pollution dans les rivières, les chercheurs sont amenés à comparer plusieurs points de données pour déterminer si une augmentation de concentration de polluant (dans notre cas des polychlorobiphényls) apparaît ou non entre ...

Initial or final values for semiclassical evolutions in the Weyl–Wigner representation

David Eduardo Zambrano Ramirez

Initial value representations are constructed to avoid the search for trajectories that are only defined in semiclassical approximations by their boundary conditions. We show how to incorporate these procedures within the full Weyl representation, so that ...

Operator-Like Wavelet Bases of L-2(R-d)

Michaël Unser, John Paul Ward, Ildar Khalidov

The connection between derivative operators and wavelets is well known. Here we generalize the concept by constructing multiresolution approximations and wavelet basis functions that act like Fourier multiplier operators. This construction follows from a s ...

The connection between derivative operators and wavelets is well known. Here we generalize the concept by constructing multiresolution approximations and wavelet basis functions that act like Fourier multiplier operators. This construction follows from a s ...

Suivi environnemental d’herbicides en Valais par échantillonnage passif sur POCIS et évaluation de l’emploi de PRC

Robin Udrisard

Les capteurs passifs comme les POCIS (Polar Organic Chemical Integrative Sampler) sont des outils de choix pour le contrôle des quantités de micropolluants dans les cours d’eau. Le caractère continu de l’échantillonnage par capteurs passifs permet par aill ...
