Since the pulse widths of the three waves are different, the core losses were measured with respect to the pulse energy to obtain the meaningful data.
The THG pulses have shown the largest reduction of ~19% over 10~25 mJ/pulse regime.
The results show that the higher optical frequency leads to more reduction in core loss.
Reduction of the core loss versus pulse energy for each laser frequency. 30 mm 280 mm 1 mm 5 mm 5 mm 1 mm Careful analysis of the data revealed that even if the peak power is same, the improvement in core loss is still better when the optical frequency is higher.
It turned out that the THG pulses were most efficient and achieved as much as 19% enhancement in core loss reduction.

Finally, the obtained CoFe2O4 samples can be used as photocatalysts with a maximum reduction rate ratio of 83%.
These results are in accordance with ICDD data no. 221086 which indicates that the sample obtained has the fcc inverse spinel structure with the Fd3m space group.
With the presence of a CoFe2O4 sample and then a photocatalyst will result in a reduction.
Reduction ratio of the photocatalyst as a function of times There was an increase in the reduction in the time variation of 10 minutes.

The effect of the heat treatment on both the catalytic activity for the oxygen reduction reaction (ORR) and the properties of ZrOxNy has been examined.
The difference of the current between under O2 atmosphere and under N2 atmosphere (iO2-iN2) was assumed to be oxygen reduction current (iORR).
The oxidation and the reduction charge of the CV were 207 and 203 μC cm -2 respectively, implying that there was no one side reaction.
In addition, no specific oxidation or reduction current peak in the CVs was observed.

The second order kinetic equation fits experimental data of asphaltene conversion adequately, giving the apparent activation energy to be 144 kJ/mol over the temperature range.
Integrating the Eq.1 gives (2) Fig. 2 shows the above kinetic equation fits the experimental data of asphaltene hydrocracking over NiMo/γ-Al2O3 at various temperatures adequately.
The data of Fig. 4 show that the average molecular weight of liquid product decreased insignificantly at 623 K and rapidly with increasing reaction severity.
Since the bond energy of an alkyl C-S bond is much lower than that of a paraffinic C-C bond [15], only the C-S bonds were split at temperature below 673 K, causing a small reduction of molecular weight of liquid.
The decomposition of asphaltenes were dominated by the scission of the C-C bonds above 673 K, leading to a large reduction of the molecular weight.

In this paper, we propose a novel location-aware medium access protocol for data intensive wireless sensor networks.
MACA-P introduces a control gap between the RTS-CTS exchange and the subsequent DATA-ACK exchange, which is used for exposed nodes to transmit RTS-CTS and for the alignment of the scheduled DATA frame transmission with the current DATA frame transmission.
To schedule concurrent transmissions, exposed terminals should be identified before the current DATA frame transmission begins.
We suppose that each node has data frame to be constantly sent, i.e. the system is saturated.

When handling the investigated problem, the decoupling of the material movement and the nodal movement (according to the fundamentals of the ALE-theory) allows for a significant reduction of computational costs.
By utilizing these data, the power flow of any drive system can directly be determined by value and direction.
A significant reduction of the number of degrees of freedom (and hence of the computational costs) could be achieved by the transition to models based on 2D structural elements (beams).
Extensive comparative analyses, consistency checks as well as measurement data retrieved from an industrial tension leveler emphasized the reliability of such simulation concepts.
A further drastic reduction of the computational costs could be achieved by a transition to a novel modeling concept based on the principle of virtual work (by employing customized parametric shape functions for the curvature and strain distributions).

If (T) is the graphic period and (∆T) the discounted reduction of this period, the increase capacity (Q) of the line is written simply as: Qmax=Q×T T - ∆T-1
Thus, for a 1000 tons capacity and 40 minutes of graphic period, the reduction of this period of one (01) minute is equivalent to a profit capacity of 25 tons.
It will be called upon a data-processing program whose process chart is illustrated in figure 2.
