Streszczenie. Animacja oparta ns symulacji fizycznej, dzięki rosnącej mocy obliczeniowej obecnie używanego sprzętu komputerowego, ma szansę zostać wiodącym trendem w komputerowo wspomaganej animacji postaci wirtualnych. Mimo niewiele gorszej jakości ruchu syntetyzowanego w stosunku do technik motion-capture wyniki są bardzo obiecujące. Słowa kluczowe: animacja fizyczna, przechwytywanie ruchu, s...

The effective analysis of the nonlinear behavior of cement-based engineering structures not only demands physically-reliable models, but also computationally-efficient algorithms. Based on a continuum interface element formulation that is suitable to capture complex cracking phenomena in concrete materials and structures, an adaptive mesh processing technique is proposed for computational simul...

Maximizing milk production without incurring ruminal acidosis is a challenge for most dairy producers. Feeding a highly fermentable diet provides energy precursors needed for high milk production, but the risk of subacute ruminal acidosis (SARA) increases. Ruminal acidosis is characterized by periodic episodes of suboptimal rumen pH, which depresses fiber digestion and possibly milk production....

Multipurpose prevention technologies (MPTs) that simultaneously prevent sexually transmitted infections (STIs) and unintended pregnancy are a global health priority. Combining chemical and physical barriers offers the greatest potential to design effective MPTs, but integrating both functional modalities into a single device has been challenging. Here we show that drug-eluting fiber meshes desi...

Global illumination plays an important role for the visual appearance of light colored hair. We present a novel approach based on photon mapping which allows an efficient physically based approximation of multiple fiber scattering in hair volumes. Our technique can also be applied to other fiber geometries like fur or woven cloth.

Abstract This study evaluated the effects of physically effective neutral detergent fiber (peNDF), and undigested (uNDF) on dry matter intake (DMI), eating behavior, ruminal fermentation, total tract permeability for finishing cattle. Simmental heifers (n=6; 667.8±28.4 kg) were used in a replicated 3×3 Latin square (21-d periods) balanced carry-over effects. Barley grain-based diets formulated ...
