This paper is prompted by a recent call by the International Commission on Mathematical Instruction (ICMI) for the study of mathematical modeling as technology-enhanced didactic inquiry into relations between mathematics and the real world. It reflects on activities designed for a teacher education course that focuses on the computer spreadsheet as a tool for concept development through situate...
<p>At present, when constructing a mathematical description of the pyrolysis reactor, partial differential equations for components gas phase and catalyst are used. In well-known works on modeling pyrolysis, obtained models applicable only narrow range changes in process parameters, geometric dimensions considered constant. The article poses task creating complex model with additional ter...
Abstract Development of numerical methods for calculating the movement gas-dispersed flows in vortex and inertial separators, creation devices with counter tangential increased dust collection efficiency, determination optimal profile corrugated channels order to minimize release droplet moisture from separators.
BACKGROUND Central to the design of a randomised controlled trial is the calculation of the number of participants needed. This is typically achieved by specifying a target difference and calculating the corresponding sample size, which provides reassurance that the trial will have the required statistical power (at the planned statistical significance level) to identify whether a difference of...
