Introduction
The conversion of nucleotide sequences to Nucleotide Genomic Signals (NuGSs) allows to operate with digital signals, thus to apply signal processing methods for the analysis of genomic data [1,2].
It has been found that the set of n = 35 samples in the sliding window can be rebuilt from m = 9 principal components, with a loss in the variance of the data set below 10-5.
The FFT block performs the dimensionality reduction produced by the PCA in Fig. 6.
This allows the replacement of the PCA block with an equivalent standard FFT block, that has the same functionality and achieves the same input dimension reduction.
The two block architecture results, in both PCA and FFT versions, in the same reduction of computing time and memory requirements.

With the ongoing energy/greenhouse emission reduction agenda gaining prominence, the relevance of implementing sustainable energy technologies is now gaining the attention of building designers around the world.
Percentage increase in lux from various systems are assessed for their commercial potential, calculations of potential reduced heat loading will become possible with ongoing data and design limitations.
The economic consequence of a few percentage points reduction in consumption would translate into millions of dollars’ worth of savings.
In the future applying practical building and design science in a climate specific context can make a substantial difference to both the short and long term gains in c02 reductions as well monetary savings.

Accordingly, precise microstructure engineering is facilitated, which results in a dramatic reduction in the consumption of expensive alloying elements and opportunities for AHSS grades.
The results are convincing that the hot core is helping to end up in a more homogenous austenite grain formation after high reduction mill, before entering the inductive heater (Figure 4).
Figure 6 gives an example of ultra-thin hot strip geometrical data measured inline after finish rolling.
Measurement of geometrical strip data after finish rolling at an ESP line.
Cold rolling setup in combination with Arvedi ESP and achievable products The cold reduction might reach up to approx. 70 – 80 % for soft steel grades, where mechanical properties for drawing as e.g. the Lankford value can be well defined and controlled, as the material of the ESP line convinces by a microstructure comparable to normalized cold rolled material.

At the same time, on the surface of metal which was in contact with aqueous solutions, electronic have plenty of opportunities to be neutralized by some substance in solution, which is the process of reduction, that is cathode process.
Common cathode process includes oxygen reduction, hydrogen release, oxidant reduction and heavy metal deposition.
Managers should adopt necessary measures for the scientific management of circulating cooling water according to the conductivity data measured by the on-line industrial electrical conductivity meter to ensure the safe and stable operation of the network and equipments.

The continuous curves correspond to the fit of the experimental data to an Avrami
type equation, ()( )ntt
X 50.0/693.0exp1 −−= , where X represents the recrystallized fraction at a time
t, being t0.5 the time corresponding to a 50% recrystallization.
For that purpose a corrected time, denoted as t*0.5, is defined as: a) b) [] [] () +⋅ − ⋅⋅ = −⋅− Ti Nb T D t t D 374.0 185 275000 exp * 15.0 06.5 0 5.0 5.0 ε (2) The use of t*0.5 allows data corresponding to different deformations and material parameters to be compared.
In the Ti microalloyed steels, different factors are probably contributing to the observed reduction in the Avrami exponent, n, with the decreasing temperature.
A reduction in the grain boundary mobility is expected from the solute drag effect and because of a decrease in temperature; furthermore the presence of solutes may enhance the reduction in mobility produced by a decrease in temperature [18].

The analysis of the XRD data reveals that all the LCMO films exhibit a cube-on-cube type of epitaxial agreement on the substrate and oriented along (h00) direction.
This apparent rise in TP far higher than bulk for the presently studied LCMO films is ascribed to i) compressive strain (c/a > 1) that leads to an improvement in the in-plane hopping amplitude [17] and ii) oxygen optimization which increases the strength of the Mn–O bond due to saturation of anion defect sites, ascertained from XRD data.
Since the c axis is decreasing with increasing film thickness, the reduction of TP is clearly correlated to an increase in the compressive strain, which results in an increase of the in-plane lattice distortion, of the LCMO unit cell [18].
The moderate reduction in the values of surface roughness along with the enhancement in grain size, apparent improvement of orientation, alignment and ordering of grains and domains, points towards the extensively improved connectivity between the grains with the film thickness.
This would result into improved electronic transport at grain interfaces due to a decrease in grain boundary region, which is accounted by the increasing film thickness, vis-à-vis reduction of resistivity and enhancement of MR at TP, in CSD grown nanocrystalline LCMO thin films.

The reduction in magnetic field density leads to a decrease in the efficiency of energy transfer between the coils.
If it is less than 10 cm, the sensor will send data to the Arduino and issue a warning sound.
The Arduino will calculate the distance the adjustment set needs to move toward the receiving coil, and then send the data to the motor control device to command the motor to rotate.

But of most noise reduction applications, the high frequency component obtained by the EMD technology is directly removed as noise.
For the rolling bearing, the impact signal related the fault is usually at a higher frequency, so, the method above does not work for the noise reduction of the rolling bearing, and it is necessary to discuss about the rule of the EMD de-noising.
Combining the previous research results and the impact characteristics of the rolling bearing fault signal, two noise reduction criterion are proposed in this paper.
Standard characteristics of various fault location are calculated by processing the measured vibration data, the standard characteristics of the outer ring, inner ring and the rolling element are respectively.
Fig.4 Fault simulation test-bed of wind turbine Fig.5 Time domain and angular domain signal of sample data in 2 minutes Fig.6 EMD decomposition diagram of angular domain signal Fig. 6 is the EMD decomposition figure of the re-sampling Angle-domain signal, and arranging it from the high to low frequency order.

Since this study was aimed at stray
grain formation in nickel-based superalloys, the material parameters that were used correspond to
those for commercial ReneN5, as calculated using the JMatPro software [2] and the Ni-DATA
database [3].
Calculations were made using JMatPro [2] and the Ni-DATA database [3] to identify compositions that lead to reduced solidification temperature ranges in these superalloys, from approximately 40 to 50 K to values of 25 K or less.
Nonetheless, it is clear that judicial changes in the alloy composition can lead to significant reductions in the equilibrium solidification temperature range.
Comparable reductions in the non-equilibrium solidification temperature range, as determined by Scheil-type calculations, were also found.
Such large reductions in the solidification temperature should have a very noticeable impact upon the stray grain formation tendencies.

The use of high strength steel materials would facilitate the reduction of self-weight of structures and associated handling, fabrication, transportation costs and erection time [6].
In the case of high strength steels, the softening and toughness reduction in the heat affected zone is the most significant.
The data in the tables are according to the material certificates, except in case of the S1300Q steel which case due to the lack of material certificate, material tests and chemical analysis were made at the University of Miskolc.
The control mode used during the tests was load reduction (preload) or constant load amplitude (crack propagation) with a load asymmetry factor of R = 0.1 and a sinuous load curve.
The data do not belong to the stage II of the kinetic diagram of fatigue crack propagation have been eliminated during the least square regression analysis, for each specimen, systematically.
