However, about 9% and 37% reduction in compressive strength in HVS cement pastes is observed due to use of 80% and 90% slag, respectively.
However, significant reduction in compressive strength is observed in higher slag-fly ash blends with increasing in fly ash contents.
Mass and differential temperature data were acquired with respect to furnace temperature.
These significant reduction can be attributed to the slow pozzolanic reaction of fly ash and slag in these HVSFA cement pastes.
However, the nano silica used in this study was synthesized by a chemical precipitation method confirmed by the manufacturer whose CO2 emission data is still not know.

Using measurements data, carried out during the experiment on real bridge structures, in situ, one can estimate the structural parameters of the bridge.
The obtained results of the updated model are useful in the process of further validation of a simulated damage test data.
The aim is to identifying damage by fitting the numerical model to real data, followed by optimization techniques, [7].
These error functions are given by the discrepancy between the predicted response and the measured NDT data of the FE model.

However, measured data were too limited to evaluate properties of (U, Pu)O2-x.
In this study, the data were expanded to a high temperature region, and the reduction curve was analyzed by fitting to diffusion model with the effect of surface reaction.
(5) The measured data were fitted by Eq. (5) using D and k as parameters.
Good agreement can be found between the experimental data and the fitted profile.
These data correspond to the dominant condition of monovacancy diffusion mechanism.

Data shown the x-ray wavelength and intensity and plotted.
The theoretical value of mass per-cent between Zn and O are 80.3% and 19.7% which the result is nearly to the theoretical data [18].
From DVR%, smaller size of nanoparticle showed greatest amount of reduction up to 40% reduction of viscosity.
Smaller size of nanoparticle exhibits a larger reduction of viscosity.

It is a linear dimensionality reduction algorithm.
The Locality Preserving Projection tries to overcome that problem by mapping the face data onto a low-dimensional face feature subspace called “Laplacianfaces”, which aims to preserve the local structure of the image space.
The idea of the back propagation is to reduce the error (difference between actual and expected results), until the ANN learns the training data.
ORL data base contains 400 grayscale images of 40 distinct subjects, 10 different images of each. 70% and 30% of images have been taken for training and testing the artificial neural network.
In the second case we only used 70%of data to train LPP.

As discussed in [16], fatigue data is in good agreement with the data reported in [10, 13].
Fitted parameters for power-law approximation of fatigue data for bare AA 2024.
This becomes obvious, if a simple power-law is fitted to the S/N-data, i.e.
The data from Fig. 4 is for both alloys in good agreement with the predicted values in the Kitagawa-Takahashi diagram.

The austenite steel was deformed by cold-rolling to 20, 40 and 70% reduction.
Then samples were deformed by cold-rolling to 20, 40 and 70% of rolling reduction.
After 40% of rolling reduction in the martensite texture the fiber α1=<110>║RD with the strongest {001}<110> orientation is still.
Magnetic investigations revealed that the volume fraction of martensite increases with the increasing cold reduction in all three melts of AISI 304 steel.
The increasing deformation to 70% of rolling reduction leads to martensite transformation γ→α’ in the steel structure.

Through the analysis of the data, the simulation algorithm in this study was proven to be successful.
Second, the vibration frequencies of the suspension system in the original data were compared after software Adams was used for the simulation, suggesting the optimized result could better play an effect on the vibration reduction of the suspension system.
The simulation data showed the optimized distribution after the optimization using energy decoupling was up to 81% at worst and proved the optimization could make the suspension system achieve a more ideal vibration reduction effect.

Results indicated that the co-remediation led to significantly greater (p < 0.01) reduction
in the lead concentration in plants than by singly adding to zeolite.
Results and Discussion The Pb concentration in shoots decreased progressively in all four zeolite doses, irrespective of the data in pot experiment I or pot experiment II.
The difference of data between no humic acid (NHA) and HA was that the lead concentration in grape roots and shoots by HA treatment declined more.
Addition of humic acids resulted in increasing of lead of water-soluble fraction and decreasing of exchangeable fraction, but the major data of content of water-soluble lead was not varying significantly.
Maybe the above could explain why humic acids just caused significant reduction of lead concentration in plants, especially aerial parts at low Pb treatment.
