Silica-gelatin hybrid aerogels of varying gelatin content (from 4 wt.% to 24 wt.%) can be conveniently impregnated with hydrophobic active agents (e.g. ibuprofen, ketoprofen) in supercritical CO2 and used as drug delivery systems. Contrast variation neutron scattering (SANS) experiments show the molecular level hybridization silica components aerogel carriers. The are amorphous, homogeneously dispersed these porous, matrices. Importantly, both fast retarded release achieved silica-gelatin...
The proper segmentation of the vascular system retina has a very important role in automatic screening systems. Its detection helps localization other anatomical parts and also possible disorders. State-of-the-art machine learning algorithms are reported to have good performance this field. However, with spatial resolution fundus images growing, it is necessary decrease number training pixels save computations. In paper, we investigate several subsampling strategies motivation find best...
Számos anyagot vizsgáltak az elmúlt időszakban, amelyeket a különböző eredetű csonthiányok pótlására fejlesztettek ki fogászatban, illetve szájsebészetben. Egy új szintetikus anyagcsalád aerogél, amely különleges tulajdonságainak köszönhetően utóbbi évtizedben orvosbiológiai kutatásokban is egyre nagyobb szerepet kap. Jelen munka célja, hogy bemutatásra kerüljön szilika aerogél előállítása, valamint jellemző tulajdonságai, mint például porozitásának, sűrűségének változása hőkezelések...
We investigate object simplification methods based on Centroidal Voronoi Tesselation (CVT) that share the possibility of great speed-ups in various scenarios. propose Constrained CVT to sample points from boundary and Region-based be able subsample lower dimensional objects, as well. Moreover we introduce custom weight functions properties. Thus, can more specific what are important parts subsampled object. also list several novel applications corresponding theoretical achievements...
Engineers specialized in multimodal tomography regularly face a wide scale of programming tasks requiring an integrated software system to ensure cost efficiency. Accordingly, development framework has been worked out comprising libraries for cluster-based data acquisition, image reconstruction, management files and complex volumetric visualization. This enabled us develop our miniPET project [Kis et al., 2005], contains graphical application integrating cluster monitoring, event sorting,...
