The challenge in corrosion modelling is rigorous calibration at the hand of sufficiently large experimental data sets, as well as field validation.
However, before considering these complex concepts, we should make sure that the basis of our research (that is, our experimental models) is rigorous.
As the constraint of D-NOSE model is more rigorous than JNDD model, the processed depth video of Silva's method is smoother than that of Zhao's method.
We show, as done previously for the case of dry gas wells (Ayala H. and Zhang, 2013, Zhang and Ayala, 2014a), that a rescaled exponential model is a rigorous decline solution that can be extended to liquid-rich gas wells producing under constant bottomhole-flowing-pressure (BHP) during boundary-dominated flow (BDF) and multiphase conditions.
Their flagship Optimum Performance Training (OPT) Model is a rigorous training system that sets the foundation for their certification program and seeks to maximize levels of physical fitness for a broad range of clientele.
To be able to construct their elegant (the fashionable word is "rigorous") mathematical models and to teach without being asked awkward questions, they assume an autonomous economy, cutting off zillions of its vital interactions with the society and its institutions, and with the real world in general.
The present model is the first rigorous and comprehensive attempt to extend the Helle Easterling Ashby model to the nanocrystalline grain-size regime.
The model is amenable to rigorous experimental design, and when appropriate data are available, model parameters can be estimated using statistically robust multi-state capture-mark-recapture models.
The model is based on rigorous homogenization procedures and the following two assumptions: that the structure is composed of either rigid or elastic blocks, and that the mortar is viscoelastic.
Since the computational time is almost the same for the two models, the rigorous model is recommended for use.
