Predicted near-field flow statistics and far-field SPL are both in good agreement with the corresponding experimental data.
Comparing with the solutions from Andersson et al. [1], our HILES predictions are in good agreement with the experimental data, especially at the locations .
Comparing with the experimental data, the locations of the peaks in and profiles are well predicted by present calculations.
Encouraging agreements between the SPL from present computational data and experimental data [1] can be observed.
Furthermore, predicted sound pressure levels are in excellent agreement with the experimental data.

However, after the capacitance
change is initiated further decrease occurs at the same rate in both the cases as shown in panel (b) of
Figure 7, by time-shifting the NOA data.
This results in an acceleration of TBR and reduction of the delay time.
The data is well described by a sigmoidal function, shown as solid line through the data.
In combination with the data presented in Figure 8, these observations suggest that the random dilution-random field crossover is perhaps a universal feature. 30 40 50 4 8 12 15 V 10 V 40 V ε T ( o C) 20 V Figure 9: Influence of the applied voltage on the photoinduced N-I transition.
Acceleration of TBR by an external field Fixed frequency dielectric constant data obtained for a planar sample (having positive εa) in the absence of an electric field (except for the probing field) and with DC voltages of different magnitude are shown in Figure 9 [23].

Reduction of European emissions has consistently demonstrated a decrease in the acidity of rainwater in Slovakia [1].
The available data on air pollution shows the changes that occurred in 2014 compared to 2004 [1].
Three different periods of monthly averages of climatic data values were compared.
Using the monthly averages of climatic data and values of the air pollution from 2003 to 2006, the maps were obtained that are shown in Fig. 2a.
The main factors obtained in this standard STN EN ISO 9223 could be based on the dose-response function uncertainty or by measurements of air pollution and climatic data.

Reduction of weight of leaf springs without any reduction in load carrying capacity and stiffness was made possible by introduction of composite materials.
The results are compared and the theory which gives the lowest value of life and the highest value is chosen to be best in the analysis of steel leaf springs Loading data is chosen as history data of SAE transmission and is applied.
Life data analysis: This is carried out by applying a load of 1000N and analysis is carried out by the above mentioned four approaches.
Also Using the Gerber’s theory the life data obtained is similar to the Goodman’s theory.
The fatigue analysis of the steel leaf springs are carried with four approaches , Soderberg’s approach is found out to give better results for the analysis of life data for leaf springs.

Thus, under the condition of positive pressure approximately equal, the positive pressure on lower contact arc will produce a greater reduction to the material of deformation zone, that is the reduction of fast rolling will be greater than the reduction of slow rolling when asynchronous hot rolling.

The tests were performed at room temperature in a static hydraulic traction machine equipped with a 100 kN load cell accuracy of 1N VERSAT 1000 model, with the data acquisition software manufacturer itself.
The wire steel suffered 56% area reduction during cold rolling.
This elevates the driving force for the precipitation of nitrogen due to the reduction of the distance of diffusion of nitrogen to the dislocations.
Thus, the amount of NbN formed was small to contribute significantly to the reduction of free nitrogen in the ferrite, which could effectively reduce the effect of static aging.
Thus, there is no effective reduction of free nitrogen in ferrite through the formation of NbN.

Introduction
The main parameter of the newly developed designs solution of machines parts aimed primarily to reduction of the weight and also an increase proportion of energy-efficient recycled materials while is requirement to maintain the same or even better properties.
This fact is important to consider during evaluating the result data (dependency of acceleration on time).
In this study has been tested an using of hyperelastic element (spring) for reduction of vibration as is shown in (Fig. 2d).
The elastic element was mounted between the arms of clamping device, which led to reduction of the vibrations.
For a further optimization, it is assumed that the final optimization of the system for reduction of the vibrations will be created with an actively controlled element.
