Analysis of the chemical equilibrium of combustion at constant volume [PDF]

open access: yesINCAS Bulletin, 2014
Determining the composition of a mixture of combustion gases at a given temperature is based on chemical equilibrium, when the equilibrium constants are calculated on the assumption of constant pressure and temperature.

Volumes of Polytopes in Spaces of Constant Curvature [PDF]

open access: yes, 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.

Volume Polynomials for Some Polyhedra in Spaces of Constant Curvature

open access: yesМоделирование 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 ...

Simultaneous ultrafiltration and diafiltration [PDF]

open access: yesHemijska 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 ...

Research on decoupled air speed and air volume adjustment methods for air-assisted spraying in orchards

open access: yesFrontiers 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.
