Volume Polynomials for Some Polyhedra in Spaces of Constant Curvature
Моделирование и анализ информационных систем, 2015 It is known that for each simplicial polyhedron P in 3-space there exists a monic polynomial Q depending on the combinatorial structure of P and the lengths of its edges only such that the volume of the polyhedron P as well as one of any polyhedron ...

Volumes of Polytopes in Spaces of Constant Curvature [PDF]
, 2014 We overview the volume calculations for polyhedra in Euclidean, spherical and hyperbolic spaces. We prove the Sforza formula for the volume of an arbitrary tetrahedron in $H^3$ and $S^3$. We also present some results, which provide a solution for Seidel problem on the volume of non-Euclidean tetrahedron.

Improving constant-volume simulations of undrained behaviour in DEM
, 2020 In order to simulate undrained conditions using the discrete element method, a constant sample volume is often assumed. There are well-recognised problems with these constant-volume triaxial simulations, particularly of dense samples, which inhibit ...

Simultaneous ultrafiltration and diafiltration [PDF]
Hemijska Industrija, 2002 A model with simultaneous ultrafiltration and diafiltration, which includes the rejection coefficients, is presented in this study. Adding a diafiltration solution at a constant, lower rate than the filtrate rate results in a constant decrease of the ...

Frontiers in Plant Science, 2023 Different fruit tree canopies have different requirements for air speed and air volume. Due to the strong relationship between air speed and air volume, the decoupled control of air speed and air volume cannot be achieved using the existing sprayers.
