Comparing to others, program 1 can not only improve voltage in maximum extend but also can make a 25% reduction of line losses.
Calculation of transformer loss reduction when DG is used to peak.
According to transformer B’s parameters, power losses reduction after adding DG for peaking could be obtained.
The data can be seen in Figure 5, adding DG for peaking can make transformer losses decreased by 23% -25%.

.), a harmonic drive (SHD-17-100-2SH, Harmonic Drive Systems Inc.) and a reduction system.
This system has advantages compared with a reduction unit using plain gears in terms of high output torque and high accuracy [1].
The input/output ratio from the original motor torque to the output axis of the reduction system is 1/100, i.e. the original speed of the motor decreases through the harmonic drive gear.
The crank shaft in the reduction system oscillated through the motor's output axis.
These graphs included three-dimensional data of the surface, and their roughness values Ra were calculated basing on the JIS B 0601:2001.

This compound exerted an efficient inhibitive action both on anodic dissolution of metal and on the cathodic oxygen reduction reaction.
This would result in a reduction of the current densities without change of the anodic slope.
The analysis of the results obtained shows that the increase of the inhibitor concentration is accompanied by a reduction of the Icorr, and consequently an increase of inhibition efficiency follows.
The reduction of anodic mainly and cathodic currents in the presence of compound inhibitor can be explained by the blocking of active sites with the formation of a protective film on the electrode surface.
The impedance data were analyzed using the equivalent circuit (EC) model, where Rp represents charge transfer resistance and Cd the constant phaseelement.

However, the tiny cracks on surface or in interior generated in ceramic preparation or processing will lead to substantial reduction in strength because of its low toughness[1].
If this phenomenon is applied in practice, improvement of reliability, reduction on cost of maintenance and increase of service life may be realized.
However, a reduction of about150 MPa for the smooth specimens can be noted after heat treated at 1200, 1300for 1 h.
The reason for this phenomenon may be that glass phases between grains boundaries melted and flowed out at high temperatures, which lead to the reduction in strength.
This agrees with experimental data as shown in Fig. 3.

1.1.2 Reduction in Costs and Convenient Construction
Steel consumption of prefabricated buildings is only 30-40kg/m2, saving 30% -40 % of construction steel.
Prefabricated components are on-site assembled after processed in the factory, reducing the turnover materials and tools as well as their leasing expense, the construction speed of part of the buildings has increased by 4-6 times, the economic benefits gained due to the shortening of construction period is considerable. 1.2.3 High Degree of Mechanization and Reduction in Equipments of on-site Construction Staff Prefabricated buildings use a lot of finished and semi-finished components for installation and construction, the labor intensity is greatly reduced, the number of on-site construction staff has fallen more than 30%, which also leads to a corresponding decrease in the number of on-site construction management staff, thereby reducing labor costs. 1.2.4 Features of Thermal Insulation and Superior Performance Prefabricated buildings can organize walls with different thicknesses and structures according to climate and temperature in different regions.
Data show that when the prefabrication rate of residence reaches to 37%, it can save water by 36%, electricity by 31%, reducing construction waste by 83%, simultaneously, achieving 60% reduction in material consumption and 50% in energy consumption. 1.2.5 Environmental Protection and Good Economy Prefabricated buildings are prefabricated and semi-prefabricated, which greatly reduces the on-site wet construction, the great reduction in construction of mould boards and cast-in-site concrete helps to reduce the impact of construction on the surrounding environment, dust and noise pollutions have been effectively controlled.

The data were scanned from 15º - 60º of 2θ at room temperature.
The XRD data of samples was found to be in good agreement with the reported XRD pattern of BaBPO5 (PDF 01-089-4624).
The data also show similarities to the pattern assigned previous study of BaBPO5: Ce and BaBPO5: Sm phases [2, 16].
The data show no peaks originating from the dopant.
Data XRD shows the BaBPO5 phosphors were evaluated to have hexagonal structure.

Buildings account for one-sixth of global freshwater usage, one-quarter of all wood harvested, and two-fifths of material use, according to data and previous studies [3-6].
The study highlights significant reductions in the decrement factor with increasing thickness and Biot number.
Further, the simulation data indicated that walls constructed with bricks containing more sludge additive exhibited greater time lag and a reduced decrement factor.
