Introduction Reactive power optimization of distribution network plays a very important role on the reduction of running costs of power system [1].
Distribution network reconfiguration based on incorporation data platform and improved PSO[J].

It is apparent that cross-linking causes an increasing reduction in the exothermic effect at 283 °C with increasing GA content up to 7.5 %, suggesting a conformational transition from random coil to β-sheet at low GA content.
Thus, a linear fit to the release data is made to obtain the release rate of Rhodamine B.

Essentially, three significant transformations as a consequence of heat treatment are observed in the oxide electrodes: (i) removal of water molecules, (ii) surface area reduction, and (iii) changes in microstructure [11].
Recently, Lee et al (2008) presented more thorough analytic data about the effects of heat treatment (100 – 400 oC) on Mn-Fe oxides for supercapacitor applications [18].

Simulation data has been used as an asset to collect two chemical compositions for the experimental study.
Vanadium has the distinguished effect on a reduction in liquid fraction sensitivity whereas Ni, Cu, Cr and Ti have slight influence in this case.

The data has been subdivided in different layers for their comparison with the MBN results.
Moreover, as the acquisition band of the MBN has not changed between the magnetic field applied at 10 Hz (Fig 4b) and 100 Hz (Fig 5), the differences seen in these two excitation modes are due to the reduction in the penetration depth of the magnetic field applied as the frequency is increased [12, 16].

After each increment, the cutter was withdrawn from the hole and the strain measured by using a computerized data acquisition system.
Cure Cycle Optimization for the Reduction of Processing-Induced Residual Stresses in Composite Materials.

In the mechanical consideration of the MLRS elevation system, because the elevation angle of the cage is in proportion to the stroke of the actuator cylinder, the vibration mechanism of the elevation system presented in Fig. 1 can be modeled as shown in Fig. 2 (a) considering both the translational motion of the actuator inner cylinder and the angular motion of the cage only by excluding the rotational motion from the motor to the ball screw reduction gear.

Temperature during welding was measured using a k-type thermocouple probe inserting 2.5 mm (1 mm in steel and 1.5 mm. in aluminium) from the bottom side of the steel sheet, with a YOKOGAWA made digital data acquisition system.
Fig.1Thermal cycle profile for (a) 50 mm/min and (b) 100 mm/min travel speed with different rpm Weld thermal cycle as shown in Fig.1 clearly indicates that higher peak temperature are obtained with increasing rpm at both the travel speed 50 mm/min and 100 mm/min because of more intense deformational heating consistent with the reduction in frictional heating.

So, reduction of mesoporous titania with vacuum atmosphere was found to be most effective.
The Seebeck coefficient data of titania film after anneal at 900oC under vacuum atmosphere was obtained.

Introduction The growing concern over global warming due to carbon dioxide emissions, the gradual reduction of the fossil fuels sources and the increasing demand for a safe supply of fuels, increases the interest in renewable and sustainable sources [1].
Data processing was performed using the compounds library NIST 05 and only compounds with similarity index (SI) greater than 80% were identified.
