The system collecting data from distribution network would compose the main data platform of power energy management in distribution network.
With these nodal data, the assumptions could be eliminated.
If the meter equipments don’t collect the power or voltage data for faults or other reasons, it is also able to operate data with the load curves.
Without reactive power data, the system assumes that the power factor is fixed; without voltage data, the system makes use of the rated voltage.
a) The data from low-voltage side of transformer.

On top of these efforts, device innovation not only brings chip size reduction, but also directly brings material cost reduction.
Data on commercial 1200V SiC MOSFET are also plotted in Fig. 2.
Fig. 3 shows the impact of the reduction of on-resistance on the active area.
With a fixed temperature coefficient of α=1.8, 50% reduction in on-resistance promises 29% reduction in active area.
Yield enhancement, and wafer cost reduction results in additional 60% chip price reduction (compare chip 2, and 3).

To generate this data, the specimens were heated by a high-density electrical current and pulled in tension to fracture at a strain rate of approximately 50 mm/sec in a Gleeble machine.
Based on the final microstructure requirements, the Gleeble data and the grain coarsening plot can be used to design an optimum thermo-mechanical processing schedule.
The data is generated on annealed plus aged material.
The data shows that alloy 783 exhibits crack growth behavior similar to alloy 718 and provides at least an order of magnitude reduction in crack growth rates over that of alloy 909.
The data reinforces the metallographic observations that salt spray resistance of alloy 783 is significantly better than alloy 909 and it is comparable to alloy 718 [6].

Analysis and results The data of GDP, TEC and TWU from TEDA’s annual Development Bulletin during 2003-2011, was analyzed for research of material consumption decoupling, while the data of GDP, COD and SO2 emissions was chosen for the pollutants study.
(remarks: all the data of pollutant emissions was from reported files of eco-industrial construction to Environmental Protection Department) Fig.2.
Liability statements of SO2 reduction target owed the assignment to key polluting enterprises.
Conclusions This paper studied the decoupling relationships between GDP and indicators of environmental pressure including energy consumption, water usage, COD and SO2 emissions based on TEDA’s data of development during the period of 2003-2011 and 2006-2010.

Collection of such data should be easy, given that the construction of databases is a direct consequence of the duties in those areas.
Using detection/assessment/warning/response/recovery data the vulnerabilities of the subsystem / infrastructure are calculated, for each scenario with allocated capacity, using the threat probability of the scenario and, subsequently, the new risk scores for each attack scenario.
Since the initial probability of a threat scenario is relative, and the reduction of it was made by implementing of technical solutions, this value is not necessarily the sum of the initial probabilities of attack.
We can suppose that the effectiveness of risk reduction can be measured as the sum of risk scores for each risk scenario on the system.
The next action is the allocation of a set of solutions for the system risk reduction.

Computer controlled data Acquisition system was used to collect and record data of the experiments.
Fig.5 Thrust force for Al/1% Mica Fig.6 Thrust force for Al/3% Mica 5.3 Effect of Wt % of Mica Reinforcement on Thrust force There was 22 % reduction in thrust force when the feed was 0.1 mm/rev for the cutting speed of 1000 rpm and 2000 rpm.
Whereas the thrust force reduction was around 13% when the feed was 0.1 mm/rev for the cutting speed of 3000 rpm.
As feed increases to 0.2 mm/rev and 0.3 mm/rev the reduction in thrust force was only around 3% to 5%.
For other feed, the reduction of thrust force was 3% to 5 % only. 3.

Several mathematical models have been proposed for determining the flow number of a mixture from the test data.
The test temperature was 54°C and three replicate specimens were tested for each data point.
Flow Number Test Data The linear regression analysis was conducted on the flow number data for each mixture to determine the significance and magnitude of the effect that the density of the mixtures had on their resistance to rutting.
The fatigue test data showed that: 1.
Compactibility of the mixtures was evaluated using the compaction data from a Superpave gyratory compactor.

According to the experiment data, a method is devised to identify the parameters of the static strength distribution function.
The actual offset may be obtained by the strength data of the laminate[8].
This may provide an angle to explain the comparatively great dispersion of the experimental data of the FRP laminate.

First experiment involved the PMMA sample drilling aiming to obtain vibration parameters that show the highest reduction in drilling temperature.
The experimental data was gathered and analyzed.
Obtained results showed 14% reduction in drilling temperatures of the vibrated bone samples if compared to the conventional drilling without vibratory excitation.
