Introduction Reductions in fuel and energy consumption, greenhouse emissions and other atmospheric pollutants are major goals for the transport sectors globally, including aerospace, automotive and rail [1].
However, the reduction of mechanical properties of laminates and the influence of composite materials under various load conditions determine battery safety, energy storage capacity and other electrical properties [8].
During the cycle, collect corresponding data every 3 seconds.

In addition, digitized data can be shared with on a real time basis through communication cable between the remote locations.[1] METHOD OF DIGITAL FLAT-PANEL TECHNOLOGY Digital RT works in the following process; (i) X-rays strike a scintillation layer firstly, (ii) this layer emits photons in direct proportion to the energy of the X-rays striking it, then, (iii) the photons are picked up by the underlying a-Si or CMOS photo-diode matrix, which converts them to an electric charge, finally this charge is then converted to a digital value for each pixel.
It is demanded to take digital x-ray detectors out of the lab and into industry which may bring cost reduction and quality upgrade in inspection.

Mechanical property Araldite® 2015 Al 7075-T6 Elastic modulus, E [GPa] 2 70 Poisson’s ratio, ν 0.33* 0.33 Tensile yield strength, σy [MPa] 14.4 448 Tensile failure strength, σf [MPa] 24.9 527 * manufacturer’s data Fig. 1.
Result and Discussion It is worth mentioning that the local moments on both ends of adhesive layer result the peel and cleavage stresses which can lead to reduction of adhesive joints strength.
Therefore, presence of local compressive/tensile stresses at critical points of bond line reduces/increase the peak values of peel stress and shear stress in adhesive layer which leads to enhancement/reduction of load bearing of the joint.

Based on the experimental results, it can be concluded that H+ ions in the system adsorbed on the (010) facets, leading to the marked reduction in surface energy of these facets.

Compared to other methods attempted, SiC doping is considered as the convenient and effective way to enhance the Jc-B properties of superconducting MgB2 despite of a slight reduction in Tc [1].
For the 600 ºC samples, SiC-doped sample shows lower Jc in small B, which can be considered as the result of the Tc reduction and the poor connectivity in this sample (8.2% vs. 9%) [4].
Since the relationship of αLdi=Jc0B satisfies, where Jc0 is the supposed critical current density when there is no flux creep and almost constant, the Labusch parameter can be simply derived as aLB3/2, which fits our experimental data fairly well in Fig. 3.

Fig. 2 Data of Bratislava airport weather station Thermal stability in summer season.
Effect of increasing the thickness of thermal isolation We tested if increasing the thickness of thermal isolation (reduction of coefficient of the heat transfer from the value demanded Un = 0,32 Wm-2.K-1 to the value recommended Ur1 = 0,1 Wm-2.K-) significantly influences indoor air temperature.
Results in the chart number 2 proved reduction in indoor air temperature of approx. 2°C.

The reduction of such killer defects is vital to improve the yield of SiC devices and put large current devices onto the market.
However, today's understanding of them is insufficient and the reported data suggests unknown killer defects still exist in SiC devices.
Reduction of threading dislocations with specific structures and improvement of the epilayer growth process are required to reduce the density of FSDs.

Boundary conditions were identified based on the previous data [10-11].
Even though the differences between the velocities may not be much, it still contributes to the reduction of air flow.
Theoretically, higher surface roughness leads to the reduction of maximum air flow velocity.
