A technical data sheet, including all information that might be used in an associated computer program in Delphi is subsequently developed.
This method is based upon observation and given data relative to the constructions.
A chart including the whole data necessary to evaluate the various parameters used and determining their categories has been developed.
It contains two parts, the user interface and the data processing.
The data processing allows to get the VI value and the structure classifications.

The disaster risk management is a complex social process that intervenes in the reduction and in the control of disaster risk [1].
· Risk Reduction (RR): the criterion defines the implementation of preventive measures and mitigation to reduce the risk
Four criteria (Disaster Management, Risk Identification, Risk Reduction and Financial Protection) have been identified.
Unlike other methods that use sample data, the method proposed here is based on expert opinions.
One key aspect of the approach proposed here is its hybrid nature, which combines real sample data with expert evaluations.

The experimental results indicate that a proper controlled reduction of the Ce-TZP phase allows a modification of the toughness of the Ce-TZP phase.
An interesting phenomenon for Ce-TZP ceramics is the possible reduction of Ce +4 to Ce +3 in a non-oxidizing atmosphere at elevated temperatures.
In most cases however, the reduction causes destabilization of the tetragonal zirconia (t-ZrO2) phase [17,19,22].
The Young's modulus, needed for the calculation of toughness from the indent-induced crack length, was obtained by the linear rule of mixtures with a data setting of 200 GPa for Ce-TZP and 380 GPa for Al2O3.
In this context, an optimum toughness increase of a Ce-TZP without spontaneous reduction was reached after 20 minutes of sintering or annealing at 1450°C [26].

The structures were refined from the synchrotron X-ray diffraction data.
The data are represented by the crosses and the solid lines are the calculated and difference profiles.
Consequently, neutron diffraction data were also collected for LaRh0.5Cu0.25Zn0.25O3 and La0.75Pb0.25Rh0.5Cu0.25Zn0.25O3 and these results are summarised in Table 1.
The composition dependence of the unit cell volumes estimated from the synchrotron diffraction data for both series are illustrated in Fig. 3.
Results of the structural refinements for LaRh0.5Cu0.25Zn0.25O3 and La0.75Pb0.25Rh0.5Cu0.25Zn0.25O3 using neutron powder diffraction data.

After oxidation, PSC at 1050°C was applied: undeformed- 5- 30- 40- 50- 60% reduction, 10s-1 strain rate. b) Comparison between the scale reduction after deformation and the reduction applied on the specimen.
Figure 3.b represents the scale reduction (after deformation) versus the total reduction of the specimen.
At intermediate reduction, these are less visible and they disappear at high reductions.
For specimen's reductions higher than 20%, scale reduction is always much higher than expected.
Quantitative data of deformation stresses have already been obtained and will be published in a following paper.

The extent of strength reduction in "t" years' operation that we named "Deterioration Factor" and limit of lifetime were estimated.
Related data, including ambient temperature in smelter building, types and concentration of gases emitted from cells, stray current through reinforcement and weight and frequency of running vehicles, are shown in table 2.
Fatigue factor of 0.8 was applied and allowable shear stress was reduced from 0.6 to 0.45 MPa, which was in good agreement with the results of supplemental experiment on the strength reduction after sustained exposure up to 300C by H.Kasami et.al.[7], in which shear strength showed a downward peak at 50C with 20% reduction.
The regression curves showed greater strength reduction for cores from beams with higher temperature, indicating rapid reduction at earlier exposure term.
(1) Compressive strength of cores by wet test showed linear reduction with operation term.

Recently, due to the reduction of oil and the deterioration of environment, people raised higher request for fuel economy and emissions, hybrid vehicle developed rapidly in most countries because of its low fuel consumption and emissions.
The simulation data indicates: PHB can improve the fuel economy and emission performance effectively with guaranteeing a good dynamic performance of bus.

These results are compared with experimental data obtained from tests on the original aerofoil geometry.
(a) (b) Fig. 3: (a) Lift coefficients (b) drag coefficients comparison Fig. 3(a) and (b) present the lift coefficients (Cl) and drag coefficients (Cd) of two aerofoils and experimental data of NACA0012.
First of all, the RANS results of NACA0012 match well with the experimental data.
At all the Reynolds numbers the results of E387 RANS computation match well with the experimental data, and meanwhile the A7 RANS results offer better Cl and Cd at all the AoA investigated.
The optimization of the surface curvature also brings a 11.27%reduction of the pressure Cd and a 5.03% reduction of total Cd although there is a very mild increase by 1.19% for the viscous Cd.

The removal of water leads to a reduction of the water activity of the food, which inhibits the growth of micro-organisms and reduces enzymatic activity and the rate of undesirable chemical reactions.
The removal of water leads to a reduction of weight and volume of the product.
The main objective of this work is to obtain experimental data on kinetics of osmotic dehydration of pumpkin and modelling them.
Osmotic dehydration kinetics is monitored by weighting periodically the samples in order to determine several characteristic parameters such as weight reduction, solids gain and water loss.
In general, the diffusional model is satisfactory but some deviations between experimental and calculated data can be observed (see Figure 3).

Data from this measurement will provide information on any potential real density reduction of the particles after the VTF process.
This is a 2.4 % reduction in comparison with the control sample.
The slight reduction in real density of the thermal treated particles is another good indication that, small amount of particles has transformed into low density censopheres [9].
Furthermore, a density reduction of 2.4 % and 3.1 % after the thermal process was recorded for both sample particle size respectively.
