Secondly, the reduction of energy consumption device as a whole due to the exclusion of reception cycle.
For this reason, the data rate can be reduced to a few hundred or less baud.
The symbol rate reduction also leads to a narrowing of the spectral power density of the transmitted signal that allows to use the frequency resource more efficiently.

The best behavior before the HAT and LAT and HRH is obtained with the specie Sphagneticola trilobata which represents 10%, 38% and 19%, therefore offering a better reduction in heat flow.

The main advantages of the SMC are disturbance rejection, order-reduction in system dynamics, strong robustness and simple implementation via power converters.
The sampling frequency of the data acquisition system is 100 Hz.
However, PID controllers cannot solve all desired requirements [21], and different tuning algorithms must be used for different needs such as disturbance reduction tuning [22] and optimization tuning [23].

AlN can be synthesized by a variety of processing methods including carbothermal reduction of Al2O3, direct nitridation of Al, chemical vapor deposition (CVD), polymer pyrolysis, and arc plasma [2].
Among them, two synthesis processes are currently used for commercial production of AlN powders: One is the carbothermal reduction method, and the other is the direct nitridation method.
Combustion temperature and velocity were measured with a W/Re thermocouple connected with a data collecting system.

The data were dotted in Fig. 4.
Oil absorbency exhibited slight reduction, with around 86.2 wt% of retention after six cycles of absorption/desorption.
This reduction is presumably due to the reason that part of PBMA was washed away since not all PBMA was crosslinked during polymerization.

Data was collected till no successive change in weight was observed.
The reduction in permeability is strongly related to a reduction in the diffusion coefficient imposed by the presence of crystallites.

As the rank of a coal increases, the surface functionality decreases due to the progressive reduction in carboxyl, methoxyl, hydroxyl and carbonyl groups [1].
Nitrogen was used for surface area measurements rather than carbon dioxide since the resulting surface areas were to be directly compared to data pertaining to bulk surface properties rather than the micropore characteristics of the coals under investigation.
Results and discussion Contact angle.The contact angle measured through water on the three coals under investigation are given in Table 3.The presence of surfactant causes a decrease in the contact angles from that measured in the absence of surfactant for the Xiangshan ,Jincheng and Baode coals, showing that adsorption of the surfactant has, in these cases, increased the wettability of these coals.The largest change in contact angle was observed for the non-ionic surfactant (TX-10), with the higher rank Xiangshan coal affected most, having a reduction in contact angle of approximately 19.13°.

In this study, the method of immersion has been carried out for 21 days (retrieval of data is taken every 3 days) at concentration which has the highest efficiency based on the calibration of potentiodynamic polatization.
It shows that the MP extract inhibitor enable to slow the corrosion rate in the sample even though it is still a reduction in weight of the sample.
This indicates that the formation of the passive layer by MP extract can lower the corrosion rate so that the specimen weight reduction in the inhibited system is not much more than the system without inhibition.

Other investigated applications of Si1-xCx include: reduction of contact resistance [3], suppression of dopant diffusion [4] and improving the thermal stability of silicides [5].
Many properties of Si1-xCx epilayers vary as a transition between the properties of Si and 3C-SiC such as the reduction of the lattice constant and increase in bulk modulus [6].
This drop occurs up to a certain threshold C composition (approximately 10%) after which the bandgap is expected to rise up to the value of 3C-SiC, although there is currently no experimental data to support these simulation results at C contents this high.
