"New advances in the mathematical modeling of the bulk continuous high-impact polystyrene (HIPS) process are presented. The model consists of three modules that allow the simulation of: (1) a polymerization reactor train...

This study aims to determine the differences in students' mathematical representations through the Problem Based Learning (PBL) model assisted by GeoGebra and Realistic Mathematics Education (RME) models, differences in ...

We examined a new method, based on the retention of fluoride (F), for estimating bone remodelling in rats and human beings. We tested the validity of the new methodology by comparing normal Sprague Dawley rats (Controls,...

Abstract The current research mainly focuses on the flow control for the two-stage proportional valve with hydraulic position feedback which is named as Valvistor valve. Essentially, the Valvistor valve is a proportional...
