Furthermore, the new method, together with ACI318, ACI440 and GB50010 ones, are verified by nine test beams in three existing experiment and show a good agreement with the experimental data.
Based on the equations for deflection predicted in ACI318[4], a set of modified equations for FRP bars was provided in ACI440[5] and validated by a great deal of experimental data heretofore.
ACI440 approach Taking into account the tension stiffening effect, ACI440.1R-03[5] suggest the use of a modified version of the Branson formation as follows: (6) where the reduction factor bd equal to (7) where ab is the bond-dependent coefficient, Ef is the modulus of elasticity of FRP reinforcement and Es is the modulus of elasticity of steel reinforcement.

We compare the latest TLS experimental data resulting from fully processed 4H-SiC wafers with results obtained by mechanical dicing technology.
In Fig.6 results of throughput calculations of an industrial TLS tool (handling and alignment is considered) and throughput data from a mechanical blade dicing process are compared.

This results in a reduction in process costs and in an increased uptime.

The optical absorption data show that the surface plasmon resonance band of gold in the visible range is greatly decreased by coating nickel phosphide shell.
For example, Huang et al. used the successive reduction process to fabricate Au@Pd core-shell nanocrystals with different shapes which exhibited an excellent electrocatalytic activity [4].
TEM images, energy dispersive X-ray spectroscopy (EDS) data, and electron diffraction patterns were obtained using a JEM-2100 transmission electron microscope under an accelerating voltage of 200 kV.
The prominent peaks basically match well with fcc Au and tetragonal Ni12P5, consisting with the SAED data.

Introduction Since the demand for the data service of use equipment (UE) has grown highly.
We perform autocorrelation calculation between PSS data in time domain and the received wireless frame data and find the maximum value.
And we just need to store only 1024 words for each group of data .So the storage memory space of local PSS is only 2048 word.
We adopt real-time data processing in order to solve problems of the massive memory needed to be created.
It means that we perform correlation calculations while receiving data at the same time, which requires that we should have accomplished the processing of the prior received data before the later data arrives.

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.

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].

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.
