The frequency response is expressed in Hz or rad/s to specify the relative reduction in the output signal at a certain frequency as shown in Figure 1.
A commonly used reduction number (frequency limit) is - 3 dB.
Assessment of Physical Sensor Parameters The data quality evaluation and assessment parameters of the sensor device provides a measurable factor that aids a better improved efficiency and output generated energy in dynamic solar tracking systems.
This reduces the relative sensitivity of the sensor to the intensity of light, causing loss of tracking focus of the sun by the solar PV module resulting to reduction in the overall generated output energy.

According to the 50 meters wind energy resource measurement data from China Meteorological Administration released in 2009, the potential land wind energy development capacity with wind power density of more than 300W/m2 is 2380GW.
Recently, with technology development and cost reduction, domestic newly-built wind farms choose this type of turbines in priority.
Due to the data from Northeast, West Neimenggu and Jilin grid, the anti-regulation probabilities of wind power are 60%, 57% and 56%.
Power corporations should collect and analyze wind power basic operation documents and meteorological data from built wind farms to establish wind power output forecast system by increasing forecast precision.
“Energy saving and emission reduction” is the mandatory requirement of power industry.

Thus, according to Balaguru [5], even with a low content, such as 0.45kg/m3, the addition of synthetic fibers causes a reduction in cracking.
Padron and Zollo [6], researching concretes and mortars with polypropylene and acrylic fiber reinforcements, obtained a reduction of 18% to 23% in the number of cracks on concrete samples.
In 2012, 331,000 tons were retrieved from waste according to data from the 9th Brazilian PET Recycling Census, published by the Brazilian Association for PET Industry (ABIPET) [11].
Figure 4: Historic data from the 9th Brazilian PET bottles Recycling Census Source: Adapted from ABIPET [11].
There is data to show that the volume of production and sale of PET packaging in Brazil may significantly increase in the coming years, further increasing the quantity of this pollutant.

Experiment and Data acquisition.
The first 10 seconds EEG data is chosen as basic data segment and steps by one second data.
By shifting the data segment step-by-step for whole trial, 5100 data segments are obtained.
Wavelet packet tool is used to analyze each EEG data segment [12].
Then AE and KC are calculated for all EEG data segments in five frequency bands respectively.

This is due to the potential of size reduction to nanometric scale to provide properties of materials such as hardness, toughness, wear, and corrosion resistance.
The impedance data for the two evaluated systems is shown in figure 4.

In the automotive industry, the hot forming of high strength steels offers the possibility to obtain significant reduction of weight without affecting the structural performances of final products.

Therefore, FLS transgenic plants containing high flavonol content showed a better in the protection photosynthetic pigments by less reductions of chlorophyll and carotenoid pigments.
Under normal daylight condition, FLS gene expression in WT background didn't show the obvious difference of flavonol contents, comparing to no expression WT (Data not shown).
Moreover, our data also present high relationship between levels of flavonols and photosynthetic pigments with R2 in the range 0.97-0.99.

Also, a data acquisition program was edited in Labview.
It was connected with the upper computer through an USB data cable.
Also the data can be lead to Matlab to draw images.

Statistic data analysis shows that neither γ variant orientations nor interface misorientations are randomly distributed within a given grain.
Thus, the data reported in Table 1.b only correspond to measurements within one grain.
Data also indicate that there is a considerable inequality between frequencies of variants within a group.
Table 3 collects statistical data relative to the sand-quenched sample (fine lamellar structure).
Actually, such a selection has already been proposed by others authors [v,x], who attributed it mostly to a reduction of high energetic γ|γ interfaces at the benefit of less energetic ones during last time of coarsening.

To minimize the impact of the global economic crisis that greatly distorted the resulting data, we calculate the SAX index for the period 2000 - 2010.
For the Slovak capital market is therefore possible to obtain the relevant data only from the last ten years.
A longer period allows to use more data, but the older the data, the weaker their importance.
Damodaran (www.damodaran.com) in the "Updated Data" section, but only the values for the whole Europe.
The calculated β values ​​therefore do not have such an explanatory power than the β coefficient calculated from the data of the developed capital markets.
