Review: Ewa Nowak 2014. Ustanawianie agendy politycznej przez media. Efekt newsa w Polsce

Andrzej Nowak

The uses and abuses of history are many. Most of them stem from the search for power rather than the truth. In a post-totalitarian country, the misremembered past may be used both against the previous regime and in its defense. From the perspective of “pure scholarship” both cases are deplorable, but the latter seems more obviously dangerous. Here we examine a few examples of this tendency in c...

Martin Nowak

Martin Nowak is Head of the Program in Theoretical Biology at the Institute for Advanced Study in Princeton. He will move to Harvard University later this year. Nowak’s work initiated the field of virus dynamics — the mathematical description of how viruses spread within infected individuals. This led to a quantitative understanding of HIV infection (see ‘Virus dynamics’, by Martin Nowak and Ro...

Hahn - Banach Theorem Bogdan Nowak

(2)1 For every set X and for all functions f , g such that X ⊆ dom f and f ⊆ g holds f X = g X . (3) For every non empty set A and for every set b such that A 6= {b} there exists an element a of A such that a 6= b. (4) For all sets X , Y holds every non empty subset of X→̇Y is a non empty functional set. (5) Let B be a non empty functional set and f be a function. Suppose f = ⋃ B. Then dom f = ⋃...

EWA Splatting

In this paper, we present a framework for high quality splatting based on elliptical Gaussian kernels. To avoid aliasing artifacts, we introduce the concept of a resampling filter, combining a reconstruction kernel with a low-pass filter. Because of the similarity to Heckbert’s EWA (elliptical weighted average) filter for texture mapping, we call our technique EWA splatting. Our framework allow...
