So noise reduction is also important.
Then we analysed the characteristics of electromagnetic radiation signal after noise reduction.
There are 2 main effects: removal ofoverlappingwaveandmakemoresymmetricwaveform.To the original signalX(t),firstly, find outall of itsextreme points. then the3 spline functionfor all of themaximum pointinterpolation,thusfittingthe original signal X(t)on theenvelope of the Xmax(t) and the lower envelope of Xmin(t).At this time,all data contained in the signals envelope.Connect envelope mean in sequence,then get a mean line m1(t),then X(t)minus m1(t) is h1(t).For differentsignals,h1(t)may be a kind of intrinsic mode function(IMF)component,it also may be not;in general,it does notsatisfy with the IMFconditions[7],the h1(t) is regard asthe original signal,repeat the above steps,namely h11(t)= h1(t)-m11(t),m 11(t) is thelower envelopemean of h1(t);if h1(t)is not a IMFcomponent,then continue toscreening,repeat the abovemethod k times, k timestothescreening of the data h1k(t)= h1(k-1)(t)-M1(1-k)(t).h1k(t)is not a IMFcomponent,there must bea screening processterminationcriterion,itcanusestandard

- Soot particles data Table 1.
) - Cutting, sliding, fatigue data Table 2.
To find a suitable Sugeno FIS which describes the selected data it is appropriate to divide the data into tuning and checking data.
There are two basic ways of dividing the data: - - dividing the area (which includes turning data) into smaller parts.

Reduction of Lanthanide Ions in Si-Al-O-N Glasses D. de Graaf1, S.
Reductions have been observed in the case of Eu3+ [3] and Ce 4+ [4], which reduce to Eu2+ and Ce 3+ during the synthesis of these glasses.
Comparison with literature data showed the simultaneous presence of Sm2+ and Sm3+ transitions.
However in contrast to the previously studied (Eu,Y)-Si-Al-O-N glasses this reduction is only partial.
This is a clear sign that the reduction process takes place during the hottest stages of the melting process, and that the reduction itself is very slow.

The drag reduction effect is declined.
The drag reduction is enhanced by increasing the contact angle.
This paper is going to combine microbubbles drag reduction technique and nonsmooth with hydrophobic surface drag reduction technique to improve the adhesion problems of microbubbles.
The interface play the drag reduction effect greatly.

The α-MnO2-CNT curve shows a significant reduction current with a reduction peak at -0.2V (versus the standard calomel electrode, SCE) in an oxygen-saturated environment.
The reduction potential of α-MnO2-CNT shifted from -0.28 to -0.32 at 1600 rpm.
The four-electron transfer reaction occurs in the following order: 2+-* (i) *** (ii) *-* (iii) *+-2 (iv) The Koutecky-Levich (K-L) equation can be used to calculate the number of electrons (n) involved in the oxygen reduction reaction, as depicted in Figure 6. using the rotating disk electrode (RDE) data for various voltages.
The K-L equation is presented as follows: (1) (2) (3) The equation used to calculate the electron transfer number in RDE data for various voltages, shown in Figure 6. is given by the Koutecky-Levich (K-L) equation.

According to the data of KSH (Hungarian Central Statistical Office)[7], more than 800 000 buildings were constructed manually from such blocks, so their examination and renovation are indeed due Fig. 2.
According to KSH census data from 2011[6].
All the further calculation models included these reductions.
This period may be further reduced by subsidies (enforced reduction of utility costs).

The size and number of carbide become smaller and lesser with decreasing the rolling reduction.
It is because of the reduction of dislocation density [2].
Stress-strain curves plain low carbon steel (a) cold-rolled to a reduction of 25%, 50% and 75%.
The data of the as-received (ferrite-pearlite) and the as-quenched (dual-phase ferrite-martensite) specimen are also shown, (b) cold-rolled to a various reduction and subsequently annealed at 500°C for 30 min.
The strength increased, but the elongation decreased with increasing the reduction. 3.

Fault diagnosis methods are researched in this paper according to NCS with long-time delay and data packet loss.
Secondly, make the state estimation error equation equivalent to an asynchronous dynamical system having event incidence constraint according to whether the system having data packets loss.
NCS fault diagnosis methods are studied in this paper according to NCS with long-time delay and data packet loss.
The time-delay only exists between controller and actuator .In addition, suppose that the data packet loss rate is fixed.
Different from the previous studies, long- time delay and data packet loss are considered in this paper ,then the state estimation error equation is equivalent to an asynchronous dynamical system having event incidence constraint according to whether the system having data packets loss .
