Application of a constant hole volume Sanchez–Lacombe equation of state to mixtures relevant to polymeric foaming
(Royal Society of Chemistry, 2018)A variant of the Sanchez–Lacombe equation of state is applied to several polymers, blowing agents, and saturated mixtures of interest to the polymer foaming industry. These are lowdensity polyethylene– carbon dioxide and ... 
Application of the FlagState Squashing Model to Numerical Quantum Key Distribution Security Analysis
(University of Waterloo, 20200918)The squashing model proof technique is a powerful tool in proving security of quantum key distribution (QKD) protocols since it reduces the dimension of the associated computational problem from infinite to finite. In the ... 
Applications of Adiabatic Approximation to One and Twoelectron Phenomena in Strong Laser Fields
(University of Waterloo, 20101220)The adiabatic approximation is a natural approach for the description of phenomena induced by low frequency laser radiation because the ratio of the laser frequency to the characteristic frequency of an atom or a molecule ...
