We present an innovative modeling and rendering primitive, called the 0-buffer. for sample-based graphics, such as images, volumes, and points. The 2D or 3D 0-buffer is in essence a conventional image or a volume, respectively, except that samples are not restricted to a regular grid. A sample position in the 0-buffer is recorded as an offset to the nearest grid point of a regular base grid (he...
This paper presents a new family of semi-implicit hybrid finite volume/finite element schemes on edge-based staggered meshes for the numerical solution incompressible Reynolds-Averaged Navier–Stokes (RANS) equations in combination with k?? turbulence model. The rheology calculating laminar viscosity coefficient under consideration this work is one non-Newtonian Herschel–Bulkley (power-law) flui...
saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. because of heterogeneous nature of cell populations, the cell population balance equation (pbe) can be used to capture the dynamic behavior of such cultures. in this work, an unstructured-segregated model is used for d...
The nucleon axial charge is calculated as a function of the pion mass in full QCD. Using domain wall valence quarks and improved staggered sea quarks, we present the first calculation with pion masses as light as 354 MeV and volumes as large as (3.5 fm)3. We show that finite volume effects are small for our volumes and that a constrained fit based on finite volume chiral perturbation theory agr...
