The turbulent kinetic energy and velocity predictions were compared between the turbulence models and with experimental data, then interpreted on the basis of the recirculation length.
(22) The turbulence model constants are obtained through a data fitting exercise.
The computational results of recirculation length for each model are then compared with the experimental data for similar investigation carried out using diesel fluid [9] in order to determine the best turbulence model.
Comparison of the predicted recirculation length (Z=1.25m) and experimental data (Z= 1.35m) for similar study done using diesel [9], showed that the Reynolds-stress model under predicted the recirculation length (7.4 % error).
However, it is important to add that exact experimental data for turbulent air flow from sudden expansion in circular ducts could not be found in literature for thorough validation of the computational results.

Less robust sensitivity indices have also been used to account for cases with lack of data, common in the oil sector.
The bathymetric data were obtained from different sources, depending on the region of the mesh.
Data for the coastal regions and the Patos Lagoon were obtained from the base of the Hydrographic Center of the Brazilian Navy6.
Figure 2 compares the data time series of the two best simulations (T1 and T2) performed in the physical calibration stage.
The field data were provided by LOCOSTE.8 4, for the initialised oil spills, respectively in ZP-19 and ZP-20 respectively.

This results in a reduction of the available nucleation sites for precipitation as well as a decrease in the driving force for recrystallization along time.
Some of the aforementioned physical parameters were back determined from the comparison between experimental data and model calculations.
The activation volume, Va, is back calculated from experimental data.
As the softening kinetics are provided by stress measurements, so as to be able to compare the predictions of the model with the experimental softening data, a hardening model incorporating the contribution of precipitation, strain and solid solution hardening is considered.
From the data the following relationship can be written: [ ] 5480 2 10862 .

The data link and interaction are both achieved by information process through the WWW mechanism.
Then, the application server receives the request and gets the data from the database server.
Ajax provides a good solution for Web application which has many interactions, frequent data manipulation and fine data classification.
The process speed is increased by eliminating downloading redundant web data.
By loading data on demand, the redundant request and response are both decreased effectively.

Gongde Guo et al. [9] suggested a method by constructing a KNN model for the data, which replaces the data to serve as the basis of classification, thus the value of K is automatically determined and is varied for different data.
Step 3 Now, we have two new data sets M and P.
Experiments and Discussion The data set.
The data set is composed of 19 thousands instances with 11 attributes.

For optimum weight reduction new materials and their fatigue behavior under real cyclic service loads have to be taken into account (Gassner test).
Figure 3: Stress-strain curves for TRIP with different cooling strategies and the reference material 42CrMo4 As the experimental gathering of cyclic material data (stress-strain curves) using strain controlled fatigue tests is very time consuming, so the much shorter Incremental Step Test is very attractive [11].

The article deals with the methods and calculations made to obtain the data on solar radiation effects on sloping surfaces oriented in different cardinal directions in regard to Saint-Petersburg weather-related conditions.
However reduction of energy consumption due to disclosure of existing energy saving opportunities is only a part of harmonization between architecture and nature.
It is possible to determine whether it is feasible to apply solar technologies if there are any data on energy efficiency (electric power generation) of solar photovoltaic modules (PV modules) and solar-based electric power system (EPS).
With this background a calculation method has been developed performing good results in regard to compliance of estimated and observed data (discrepancies do not exceed 8%).
These correction factors have been obtained on the basis of estimated and observed data made at 50 scientific stations located within the territory of the Russian Federation.
