An Ocean of Information. Information overload faced by Internet users
(Polska Akademia Nauk, 2011)
As the amount of online content grows, Internet users’ attention span decreases. This brings an acute need for social and technological solutions that enable users to select the most important and relevant information.
Author disambiguation in the YADDA2 software platform
SYNAT platform powered by the YADDA2 architecture has been extended with the Author Disambiguation Framework and the Query Framework. The former framework clusters occurrences of contributor names into identities of authors, ...
Analysis of Gravitational Wave Signals on Heterogeneous Architectures
Heterogeneous architectures and programming techniques will be very important in the development of exascale HPC applications. Adapting heterogeneous programming techniques to scientific programming is not always ...
Adsorption of Hydrogen at the GaN(000-1) Surface: An Ab Initio Study
(American Chemical Society, 2015)
ABSTRACT: Ab initio calculations are used to determine the basic physical properties of hydrogen adsorption at the N-terminated GaN(0001̅) surface. It was shown that the Fermi level is pinned at the valence band maximum ...
Computational study of structural and elastic properties of random AlGaInN alloys
(IOP Publishing, 2010-04-26)
In this work we present a detailed computational study of the structural and elastic properties of cubic AlGaInN alloys in the framework of Keating valence force field model, for which we perform an accurate parametrization ...
The Neumann problem in an irregular domain
(EMS, Interfaces and Free Boundaries, 2010)
We consider the stability of patterns for the reaction-diffusion equation with Neumann boundary conditions in an irregular domain in ℝN, N ≥ 2, the model example being two convex regions connected by a small ‘hole’ in their ...
Między alienacją a adaptacją : Polacy w wieku 50+ wobec internetu

Raport analizuje korzystanie z internetu przez osoby w wieku 50+ oraz podejmuje kwestie cyfrowego wykluczenia osób starszych. Na potrzeby raportu przeanalizowane zostały wyniki najważniejszych badań dotyczących korzystania ...
Diffusion in crowded biological environments: applications of Brownian dynamics
(BioMed Central, 2011-03-02)
Biochemical reactions in living systems occur in complex, heterogeneous media with total concentrations of macromolecules in the range of 50 - 400 mg/ml. Molecular species occupy a significant fraction of the immersing ...
Data model for analysis of scholarly documents in the MapReduce paradigm
At CEON ICM UW we are in possession of a large collection of scholarly documents that we store and process using MapReduce paradigm. One of the main challenges is to design a simple, but effective data model that fits ...
