Engineering intelligence model and data analysis
In order to achieve the aim of a complete overview of the calculated data, the authors have used an innovative approach based upon the OLAP (On-Line Analytical Processing) databases.
To support users during the process design development phase in the generated data management.
In fact different data aggregation rules have been implemented.
The structuring and aggregation of the generated data allow to the same data to be a reference base for the performances analysis of the analyzed test case. 3.

Bessert [6] elaborated applications to transfer IT-based data in
his research activities.
The transfer data is written in *.ASCII-format (text format), which is easy to interpret.
Potentials for reduction are the idealising of the process-structure-effects, the coarsening of time lags within the FEMcomputation, the coarsening of the FE-mesh or the homogenisation of anisotropic and temperature depending material data.
With regard to Fig. 1 the reduction can be performed by an analysis of the sensitivity of exemplary parameters (design of mesh and geometry, material data, time steps: transient vs. quasi static).
Concerning the materials mentioned above the database is complemented by experimental data provided by the subproject A3.

Two different pavement projects were generated with hypothetical data to illustrate the ability of the proposed method to compare the overall performance of different projects, and a sensitivity analysis of the discount rate was also studied and discussed.
As the mileage is linearly related to the toll, the converted full flow can obtained according to the natural flow and charge data for each class of traffic.
Test with Hypothetical Data Hypothetical data for two different pavement projects were generated to illustrate the ability of the proposed method to compare the overall performance of different projects.
Results and Conclusions An economic and user service-based evaluation method is proposed to evaluate the overall performance, it is rudimentary but it demonstrates it capability to evaluate overall performance using hypothetical data.
l Real test data are needed to validate the proposed method.

Experimental Determination of the Strength and Modulus of Elasticity Static Bending Laminated Composites
Determination of strength and modulus of elasticity in laminated composites based cotton fabric presents considerable difficulties, but the data used for design calculations can be obtained using the method (based composite materials cotton fabric and phenolic resin).
The data can be plotted directly on force-displacement coordinates.
To determine the material data used tensile testing machine INSTRON type 5587 and the program of experimentation is based on the following: - three thicknesses were chosen the elements of the 2, 6 and 10 mm; - were made sets of five specimens for each material thickness type 2082 HGW manufacturer specifications.
It was agreed at this stage: test type ( Type ), data material (specimen shape, material thickness, specimen width, the distance between the car and the distance between landmarks jaws between which measurements) speed traction machine limits the rate of acquisition machine (10 points / second) output file type (ASCII or DIF - data Interchange format, a file format that can be picked up any statistical data processing programs ), the type of output data will be collected (the program provides users an estimated 200 data types specific to each type of test); output data samples are breaking force [kN] , elongation [mm] maximum voltage reached in the material [MPa] , elongation corresponding relative maximum voltage of the material [%]; outside data speci0fied above, save the raw data of such tests (characteridtic curve coordinates force [kN] – displacement [mm].
This data is found in the form of pairs of points in the coordinates above each analysis in ASCII format.

Most research work is limited to experimental results, but, also, the modelling of hard turning can provide useful data to better understanding the process.
Furthermore, experimental data must be on hand prior to the construction of the model in order to determine the chip geometry.
Furthermore, it includes a wide database of workpiece and tool materials commonly used in cutting operations, offering all the required data for effective material modelling.
The proposed oblique cutting model for dry high speed hard turning can provide, as in the case of 2D modelling, much useful data.
The proposed oblique cutting models are in a position of providing the same data as the 2D models, but also some additional information, e.g., for the 3D formation of the chip.

Main geometrical data
incremental forming
As above described, deformation mechanics is basically stretching, i.e. it causes a corresponding
thickness reduction according to material incompressibility [15].
The measurements were repeated on different sections on all the walls of the specimen in order to check the data coherency.
The lowest step size leads to a thinning reduction and a more homogeneous thickness distribution.
A certain variability in the experimental data was in fact observed, due to both measurements accuracy and probably also to other phenomena; in particular the role of planar anisotropy deserves, according to the authors's opinion, a more detailed investigation.
These problems involved also relevant difficulties in the prediction of thinning: only a very careful and continuously monitored simulation permitted to obtain predicted thickness values closed enough to the experimental data.

The
major benefits of this technology compared to conventional slab casting are a reduction of between
35-45% in capital costs, it is 7.5 times more energy efficient, and a 70 to 90% reduction in CO2,
NOx and SO2 emissions [1],[2].
Similarly, a reduction in surface tension was shown by these researchers to enhance the heat transfer rates, as a more intimate contact was achieved.
The movement of the ram triggers magnetic switches, which initiate the data recording and turn off the induction generator resulting in the droplet settling on the substrate.
This novel technique does provide data on the transformation path, but is restricted to a time resolution of 500 ms.
