Basic noise reduction was applied for all maps and grain identification was performed (at least 2 connected pixels of the same kind were required to define a grain).
To improve statistics, the inverse pole figure in Fig. 3 shows the superimposed data of 4 different measurements.
Fig. 3: Inverse pole figure of 4 measurements (superimposed data) obtained for Ni–18 wt.% Fe after annealing for 30 min at 300°C (y-direction is parallel to growth direction).
After noise reduction, about 30% of the investigated surface area is still un-indexed which is mainly due to overlap of patterns at grain boundaries.

In this paper, static and dynamic simulations of 10 kV 4H-SiC diodes using Sentaurus TCAD are combined with calculation of lifetime profiles estimated by SRIM [5] and DLTS data from the literature.
This value is tuned to produce experimental values of forward voltages comparable to the measured data [6, 8].
The plasma level and speed of plasma reduction are both related to proton-induced defects location.

Introduction Driven by the regulation of the European Union to reduce the CO2 emission from passenger cars to 95 g CO2 per kilometer till 2021, one approach for future cars is weight reduction.
Data from refs.[6-10] One of the challenging aspects for manufacturing AMCs via a casting process is particle incorporation into the matrix melt is.
No data on wetting properties of amorphous boron with liquid aluminum has been published so far, but aluminum can react with boron to AlB2 at high temperatures promising reactive wetting [15].
In comparison to the addition of Ti alloying of Zn to aluminum is beneficial due to the reduction of the liquidus temperature, which makes Al-Zn alloys interesting for casting processes.

Each experimental run included a minimum of 5 replicates, with the key data of tensile modulus and tensile strength presented as average values and standard deviations.
Specifically, SW40 exhibited a 50% reduction in tensile strength compared to pure PBAT.
A reduction in the tensile strength of the composites may be correlated with the early failure of the samples, which is anticipated when rigid particles are integrated into the polymer matrix.

An examination of the experimental data for the 64 cuts has shown that the total depth of cut increases with the number of passes, as might be expected, so that multipass cutting is an effective means to increase the AWJ cutting capability and application domain.
The experimental data show that nozzle oscillation has significantly increased the depth of cut by an average of 45.43% as compared to that in normal cutting under the corresponding cutting conditions for single-, double- and triple-pass cutting.
However, the rate of kerf taper reduction decreases as the number of pass increases.
For all the tests in this study, oscillation cutting reduced the average kerf taper from 5.43 o to 3.43 o , representing a 36.8% reduction.

Many experimental studies and analytical on the geothermal exchanger are available in literature: Francis [3] presented experimental data showing the performance of earth cooling tube system in the Midwest Region of the USA.
Additionally, the weather data, radiation processor and sky temperature TRNSYS types [11] were incorporated to the complete modeling task.
In fact, by using tube length more than 60 m, the cooling energy reduction will be negligible; - Regarding tube depth, a good compromise between energy performance and excavation costs is preferable with a depth of about 2 m; - Air flow rate of 200 m3/h is recommended when the efficiency of the system is 85% Finally, in summer conditions, EAHE with nocturne ventilation and mass inertia of walls have been coupled and simulated to evaluate indoor thermal comfort conditions.
A reduction of the internal temperature of 5°C has been found.

WQI is a mathematical method to transform large quantities of water characterization data into a single number which represents water quality classification.
This reduction is caused by passing the river through populated centers and entrance of waste water to the river.

Complex constitutive model which captures material behaviour such as plasticity, fracture mechanism through stress-strain data obtained at both quasi-static and large strain rates were implemented to adequately relate simulation to the physical problem.
In this work, data for the Johnson-Cook plasticity and failure models which express the equivalent flow stress as function strain rate, strain hardening and temperature for both target steel and projectile were taken from references [1,20].
There was a reduction in initial velocity of projectile to a residual velocity value of 460 m/s.
Variation in velocity reduction for both S2-W1-S2 and S2-W2-S2 models (refer to Fig. 5 for notation) were very small.

Data Reduction.
This model was presented better agreement in measured data at the current geometry [8].
However this priority on heat transfer enhancement was changed to the trapezoidal obstacles with increasing height in flow direction (case 4) at upper wall due to reduction on low heat transfer areas which were produced at the corners of the obstacles.

.): i) the distortion of the historical urban context, due to the inclusion of hypertrophic buildings having questionable architectural and functional quality; ii) loss of architectural heritage, businesses, jobs; iii) reduction of the amount of services supplied to citizens and of the close relationship with local traders (sometimes farmers), due to the progressive reduction/closure of stalls (about 30% in the Milvian Bridge market) [5] and to the operators’ turnover; iii) local collective initiatives disadvantaged with respect to opportunities offered to business interests of people alien to the local context, who can thus exploit the favorable returns of privileged locations with consequent decreases in the business goodwill value (from about € 50,000 before the intervention – 2004 - to € 15,000/25,000 after the intervention – 2009 - at the Trionfale market) [5] and lack of ‘attractiveness’ in the rental market of commercial premises on the floors above the market area.
Synthetic technical data concerning the market (from MR’s pre-feasibility study, the three project ideas, status and new proposal) is shown in table 1.
Table 1 - Synthetic technical data concerning the market (MR’s pre-feasibility study, ideas/project, status and new proposal) The pre-feasibility study prepared by MR for the Flaminio II market [8] estimates the costs of the works as € 5,926,000, with a total capital cost (economic framework) of € 7,051,940 in 24 months.
