Abstract An algorithm to re-create virtual aggregates with realistic shapes is presented in this paper. The has been implemented the Unity 3D platform. idea realistically coarse and crushed that are normally used as a material for construction of roads. This method consists two major procedures: (i) combine spherical density function noise matrix based on Perlin obtain appropriate angularity an...

With the increasing availability of surface extraction techniques for magnetic resonance and x-ray computed tomography images, realistic head models can be readily generated as forward models in the analysis of electroencephalography (EEG) and magnetoencephalography (MEG) data. Inverse analysis of this data, however, requires that the forward model be computationally efficient. We propose two m...

cytology of ustialgo maydis teliospore, basidiospore and mycelium was investigated with epiflouresent microscope using both ethidium bromide and ocridin orange. surface sterilized teliospores were cultured on pda + 10% dextrose medium and incubated at 25ºc for 5 days. the results revealed that nucleus in teliospore occupied most of the inner part of its cell. sporidia had an ellipsoid shape nuc...

To assess the mechanical response under traffic of asphalt mixtures, a typical practice is to perform complex modulus test. In this work, test reproduced numerically for an mixture by 3D simulations carried out with LMGC90 code. A viscoelastic contact law used handle interaction between particles irregular shapes. The numerical aggregates were generated using particle size distribution (PSD), f...

ABSTRACT Understanding the cellular organization of tissues is key to developmental biology. In order deal with this complex problem, researchers have taken advantage reductionist approaches reveal fundamental morphogenetic mechanisms and quantitative laws. For epithelia, their two-dimensional representation as polygonal tessellations has proved successful for understanding tissue organization....

Analytical solutions to the magnetic forward problem are known only for special volume conductors [1, 2, 3], which are insufficient to describe detailed head shapes. The forward calculation for a realistic volume conductor can so far only be solved by numerical algorithms, such as the boundary element method (BEM) [4, 5, 6, 7, 8, 9], which pose severe problems for superficial sources due to the...
