Thermodynamically consistent modeling of yield surface distortion

Thermodynamically Consistent Quasi-Newton Formulae

Newton and quasi-Newton methods have been used in chemical process design and optimization calculations for quite some time. They continue to be used today, both in the traditional sense and as part of the more recent hybrid method. While Newton-based fixed-point methods have been used to solve many different kinds of chemical process design and optimization problems, perhaps the point of singl...

Qualitative Behavior of Solutions for Thermodynamically Consistent Stefan Problems with Surface Tension

We study the qualitative behavior of a thermodynamically consistent two-phase Stefan problem with surface tension and with or without kinetic undercooling. It is shown that these problems generate local semiflows in well-defined state manifolds. If a solution does not exhibit singularities in a sense made precise herein, it is proved that it exists globally in time and its orbit is relatively c...

Consistent Re-Calibration in Yield Curve Modeling: An Example

Modeling Cassava Yield: a Response Surface Approach

This paper reports on application of theory of experimental design using graphical techniques in R programming language and application of nonlinear bootstrap regression method to demonstrate the invariant property of parameter estimates of the Inverse polynomial Model IPM in a nonlinear surface.

Consistent Yield Curve Prediction

We present an arbitrage-free, non-parametric yield curve prediction model which takes the full discretized yield curve data as input state variable. The absence of arbitrage is a particular important model feature for prediction models in case of highly correlated data as, e.g., for interest rates. Furthermore, the model structure allows to separate constructing the daily yield curve from estim...
