The two-dimensional single-channel model uses a boundary-layer approximation including detailed models for heterogeneous and homogeneous reactions as well as transport phenomena.
Experimental results in the seawater desalination plant at the Plataforma Solar de Almería (Spain) show good agreement of the model and real data despite the approximations included.
The difference between the cases of a linearly changing and a constant leakage current density is, however, so small that it would certainly vanish in errors due to many approximations included in theoretical models.
There exist a few methods for bispectrum approximation, including models with our without parameters.
This is a finite-difference model that solves the dynamic and thermodynamic equations forward in time under the anelastic approximation including microphysics in a parameterized form.
The method also works well with other rough approximation models, including kernel average smoother and nearest neighbor smoother [17].
The approximation models include an estimation model for obtaining material non-proportional cyclic hardening coefficient, and a simple multiaxial fatigue life estimation model for steels based on hardness as the only required material property.
The difference can be due to several factors, including model approximations (e.g., limited number of elements in the system as compared to number of CNTs in macro-sized experimental samples) or CNT dispersion conditions during sample preparation.
To facilitate the reading, the details of the model construction, including the used approximations and their justifications, and the equations used for the description of the SBSP models were concentrated in this section.
Using a newly developed envelope function approximation model that includes interface effects, several InAs/GaSb type-II superlattices (SL) for the 4 μm (around 310 meV) detection threshold were designed.
Mathematical models include approximations that limit their accuracy.
