It evolves with a high speed traditional transformer in addition to power electronic base construction will eventuate to oil elimination, dimensional size and weight reduction.
It will provide a platform for delivering the traditional power with new services evolving the exchange of data and information in a dynamic style.
A multi level Intelligent Universal Transformer (IUT) emerging a next-generation of distribution transformers base on power electronic construction for incoming distribution automation [20]. automatic sag voltage compensation, real-time voltage regulation, outage compensation, Flicker mitigation, capacitor switching protection, harmonic compensation in nonlinear loads conditions, DC output service, reliable diverse power as variable frequency like 400Hz option, storing power, dynamic system monitoring, output voltage compensation in case of the built-in energy storage, capability on delivering three-phase power from a single phase, oil elimination, size and weight reduction are the most advantages of IUT rather than current traditional transformers [16], [22].

In addition, they can be produced extensively in substitution to all materials used in the coating of almost all heating equipment as well as contributing to the reduction of energy consumption.
According to data furnished by some suppliers, ceramic wool and glass wool have their theoretical compositions as described in Tables 1 and 2, respectively.
Fig 5 – XRD of glass wool residues Fig 6 – XRD of ceramics wool residues Conclusions The glass and ceramic wools presented good performance in grinding, with easy size reduction.

The elongation to failure and reduction in area are 22% and 28%, respectively.
The values of K' and n' determined by the log-log linear regression analysis of the test data obtained by both the CST and the IST method in the individual region of the plastic strain, i.e. %2.0≤pε and %2.0≥pε , are listed in Table 4.
This two-slope C-M behavior indicates that the actual fatigue life of the alloy tested at low strain amplitudes ( %2.0≤apε ) is less than the life anticipated from extrapolation of the data points of high strain amplitudes ( %2.0≥apε ).
The strain fatigue data are analyzed in the individual region of plastic amplitudes, i.e. %2.0≤apε and %2.0≥apε , using a least squares analysis according to Eq.(2).
The two-slope of the C-M plot indicates that for GH4145/SQ alloy prediction of fatigue life, at low strain amplitudes, based on extrapolation of high strain amplitude data could be quite erroneous and might results in overestimation of fatigue life.

According to the leakage detection and repair work statistical data of oil refining enterprises, nearly 80% of valves used in refining unit are gate valve [1], with two kinds of external leakage internal leakage.
To extract useful information from the acoustic emission data, the acoustic emission power can be calculated by root-mean-square value.
Finally, valve internal leakage AE signal RMS value is transported to computer by USB data cable, and computer stored data can decide internal leakage and give result.
Firstly, closed experiment valve and opened ball valve, high pressure nitrogen gas bottle, reduce valve, then, set data acquisition threshold value at 5dB, sample signal as background signal, as shown in figure 3.
With the internal leakage data at the same different pressure and different detect points, signal at sealing face downstream is the strongest, followed by the upstream, bottom and front.

The primary physiological data required for identification of loss of SA were identified as fixation duration, fixation locus and pupilliometric data.
The Line of Sight, Computation and Target Intersection Software allows for reduction of the collected data to a list of fixations.
The simulator data analysis software correlates the eye fixation data from FaceLAB™5 with the dynamic simulation scenario in real-time.

The specifications for the inspected pump, as outlined in the data sheet, are provided in Table 1.
The workflow in this study comprises five stages: data collection, data processing, post-processing, interpretation and corrective action, and finally validation and evaluation.
Established diagnostic methods are applied to interpret the data and support informed maintenance decisions.
Request refers to vibration data collected based on specific requests from operations, usually when abnormal pump behavior was suspected.
The data categorized under request were selected because they recorded the highest vibration levels, while data from surrounding dates showed similar values but were less critical.

l Reflect the real-time data and device status: the telemetering and remote data omission are Refreshed every 5 seconds On the screen, which immediately reflect for the conjugation of telemetering and the conjugation of remote data omission, At the same time according to the color of the system configuration table to distinguish the telemetering and the different states of each equipment.
l Reflect historical data: the graphical browser brings up the history of any period of Historical data.
When the data saved by the users, DBI has conducted security checks again according to this definition of commercial database table.
Would the adjustment of power grid operation mode result in the abnormal condition in power grid such as the overload of line or reduction of the grid reliability?
The data synchronization of graphics and model for simulation system[8][9] In order to attain the goal which the simulation of fault handing for power distribution automation and the graphics and model data of training system keep quasi real-time synchronization with control centre system of distribution automation for Changchun, the system need to keep graphics data synchronized with model data when the graphics and model data in which the control centre system of distribution automation for Changchun changed.

The importance of the customer requirements and relationship strength were identified as linguistic data.
We have collected data for the criteria from the decision makers of the automotive industry.
Step 4: Fuzzification of input data: In this step, the input data are further represented in triangular fuzzy number (TFN) as demonstrated in table 1.1.
For three decision maker we have taken average of importance for respective data.
The next step is to do fuzzification of the input data as demonstrated in the table 1.1.

Adsorption mechanism of modified peanut shells for Cr(VI) was both physical adsorption and chemical adsorption of adsorbent "adsorption-oxidation and reduction processes".
The data were fitted to the Langmuir isotherm equation ρe /q=1/KbAs+ρe/As (where Kb is the binding constant, As is the saturated adsorption amount) and the Freundlich isotherm equation lgq =lgK+1/nlgρe (where K and n are Freundlich constants) respectively, as shown in Figure1.
The data were fitted to the equation -ln(1-F) = kt, where F = Qt / Q∞, t is time, Qt and Q∞ are the adsorption amount at reaction time t and at equilibrium respectively, and k is the rate constant of the adsorption.
