Degree of Conversion of Polymer-matrix Composite assessed by FTIR Analysis [PDF]
The Journal of Contemporary Dental Practice, 2013 ABSTRACT Aims and objectives The behavior of polymer-matrix composite is dependent on the degree of conversion. The aim of this study was to evaluate the degree of conversion of two resin cements following storage at 37°C immediately, 24 and 48 hours, and 7 days after light-curing by FTIR analysis.

Effect of the Mass Conversion Degree of an Oxygen Carrier on Char Conversion and Its Implication for Chemical Looping Gasification [PDF]
, 2022 Chemical looping gasification (CLG) is an emerging process that aims to produce valuable chemical feedstocks. The key operational requirement of CLG is to limit the oxygen transfer from the air reactor (AR) to the fuel reactor (FR).

A Converse Sum of Squares Lyapunov Result With a Degree Bound [PDF]
IEEE Transactions on Automatic Control, 2012 Sum of Squares programming has been used extensively over the past decade for the stability analysis of nonlinear systems but several questions remain unanswered. In this paper, we show that exponential stability of a polynomial vector field on a bounded set implies the existence of a Lyapunov function which is a sum-of-squares of polynomials.
