Results show a reduction in system energy losses for the optimized values, without violating any power system requirements.
Two case studies will be conducted by utilizing the data from a typical 132kV main intake substation; and simulated using DIgSILENT® PowerFactory software [8].
Instead, the 24-hour energy loss (in kWh) of the feeder is to be minimized, which is calculated as below: Eloss= t = 024 - ∆tPloss(t) × ∆t (1) Ploss(t) is the active power loss of the network (in kW), returned by PowerFactory after the load flow for corresponding data at time t is executed.
∆t is the time period, taken as 0.05 hour (or 3 minutes), which is equal to the smallest available duration of data sampling.
The middle penetration appears to give the most loss reduction for this case, which is somewhat similar to the total base load of the feeder.

Energy conservation, consumption reduction and emission reduction are inevitable choice for an enterprise on technology improvement and sustainable development.
It suffers a heavy pressure on the energy conservation and emission reduction.
This suggests that oxygen-enriched combustion indeed have effect on energy saving and consumption reduction. 3.3.2 The influence caused by enriched oxygen on energy consumption of producing clinkers In the normal production, Jiahua cement clinker sintering energy consumption can meet the design index and close to the domestic advanced level during the Oxygen enriched test(generally production line of about 750 kCal / t, the advanced level of 650 kCal / t, the production line design value of 740 kCal /t); (1)Oxygen-enriched during the trial make average clinker claiming reduce energy consumption by 2.07%,every day is equivalent to the 15 tons of coal (if it is a high-quality coal, the coal saving rate will be higher); (2)Test data analysis shows that, oxygen-enriched combustion mainly in the kiln head quarter in coal is obvious, the average of 8.38% firing fuel consumption is decreased , the kiln outlet coal is decreased by 1.49% on average (according to the data in table 13 can be disassembled
The daily amount of CO2 emission reduction is 24.2t / d, according to 320 days per year in calculation.
Every year the CO2 emission reduction is 7744 t/a, which is beneficial for society. .

Cone data indicate that the incorporation of 1% GNP leads to a 28% reduction in the peak heat release rate (PHRR) compared to pure PS.
Measurements The X-ray diffraction (XRD) data were obtained at room temperature using a Rigaku Miniflex II Desktop X-ray diffractometer equipped with a Cu-Ka source (λ=1.5404Å).
Increasing the GNP loading does not result in a further reduction in PHRR; the reductions are 20.3% and 19.5% at 2% and 3% loading, respectively.
As can be seen from Fig. 3, the addition of 20% intumescent flame retardants (IFR) into PS results in a 54.8% reduction in PHRR in comparison with pure PS; the reason for the reduction is probably attributed to the formation of excellent char.
The addition of 20% intumescent flame retardants (IFR) into PS results in a 54.8% reduction in PHRR, and a further reduction in PHRR (64.5%) is observed if 3% IFR is substituted by GNP (i.e. 17% IFR + 3% GNP).

The higher reduction Δh was required, the higher was the number of passes of the sheet through the rolling stand.
The higher reduction is required, the higher will be the proof stress Rp0.2, and tensile strength Rm and also the smoother will be the forged piece surface.
Fig. 1 –Influence of tensile strength on mean arithmetic deviation of the surface profile in deep-drawing steel The diagram shows linear regressions of the measured data of the samples „C“ and „D“ with the reliability value R2 and equations of linear regression.
On the basis of identification of relations between technological parameters of the technological process we obtained from the regression analysis of experimental data the equations for the reference material KOHAL.
Table 2 presents numerically individual parameters in respect to the real measured absolute reduction ∆h.

Data processing is very important for evaluation.
Firstly, evaluation indicators are collected and classified into input indicators and output indicators for data processing.
The data are shown in Table 1.
Specific steps are as follows: (1) the original data forward and standardization.
Standardized data are tested for KMO measure and Barelett spherical test to determine whether they are suitable for Factor Analysis.

The influence of both strain amplitude and strain mode on the development of the deformation and recrystallization textures is discussed based on experimental data and results of crystal plasticity calculations. 1.
The results are discussed based on experimental data and results of simulations with crystal plasticity models. 2.
The orientation data were post-processed with the MTM-FHM software [3].
To the purpose of obtaining a reliable comparison between deformation and recrystallization textures, all orientation data were post-processed with the MTM-FHM software.
Both experimental data and results of crystal plasticity calculations show that recrystallization is controlled by low stored energy nucleation, i.e. nucleation is favored on microstructural sites with less than average stored energy.

A sample of C-150 noise data reconstruction taken at t = 0.0 until t = 1.65 s Fig. shows the reconstruction of C-150 noise.
The data is taken at t=0.00 until t=1.65 second.
The data shown in Fig. 4 and those reconstructed and shown at fig. 10 are taken from a distance of 20 m at an elevation of 1.2 m exactly at the left of the C-150 aircraft propeller.
The data is then analyzed using FFT (Fast Fourier Transform) analyzer to obtain the frequency response.
The data is then inverted to obtain the anti noise source.

Reduction of Hematite by Electrical Discharge Assisted Milling D.
Preliminary discharge milling experiments performed under arc conditions have demonstrated that this technique can be employed for initiation of reduction reactions in metal oxides.
However, further reduction of magnetite to FeO [6] during room temperature milling has proved more difficult, in part, due to the large positive free energy change associated with the latter reduction reaction.
XRD outputs were analysed with Traces Software (GBC Scientific) with search-match capability using the International Centre for Diffraction Data (ICDD) powder diffraction file, 2003 Version (PDF-2).
Semi-quantitative EDS analysis of large sample areas revealed increases in average iron content with increases in milling time, confirming that chemical reduction occurred during discharge milling and that the amount of reduction increased with increasing discharge milling time.

Effect of Argillites Reduction Ratio on Ceramic Tile and Paving Clinker of Low-Temperature Sintering A.V.
In given intervals of reduction ratio and firing temperature the index of water absorption capacity of less than 5 % needed for ceramic tile is achieved by size reduction of 0 – 0.315 mm and firing temperature of 1000 °C and higher.
For Vladimirovskoye deposit in given intervals of reduction ratio and firing temperature the index of water absorption of 5 % is achieved by size reduction of 0-0.315 mm and firing temperature of 1050 °C and higher.
Considering that laboratory data, in principle, don`t entirely have to focus on upper limit values, we can use an average index of water absorption capacity of 1.5 % for paving clinker and 3.5 % for ceramic tile.
In this case, the necessary indexes are achieved at higher firing temperatures and finer reduction ratio of the raw material.
