The Upsell Equation Review

Equation Service is a program that uses pdflatex to produce small PDF files containing equations and other text. You can either do the input and typesetting in the main Equation Service window and then drag and drop the resulting PDF into your application, or highlight text in the other...

Planar String is a small program written in Java that allows to explore the evolution of an elastic string moving in the plane. Mathematically, it provides some insight into the dynamics of the wave equation. The motion of the string is prescribed by configuring its positions at time 0 and at...

The program computes phase envelopes for two binary mixtures containing ethane and benzene (20 % ethane and 80 % benzene; 70 % ethane and 30 % benzene). This binary system exhibits a peculiar behavior called retrograde condensation (e.g. We get condensation as we increase the temperature or...

The programs compute the vapor-liquid diagram of an ethane-benzene mixture at 25dlT-C and 175dlT-C. This binary mixture exhibits a peculiar behavior because the volatilities of ethane and benzene are very different. We use the SRK equation of state to compute equilibrium constants. This problem...
