Consequently, the high concentration of CO2 stream produced by the oxy-fuel combustion, leads to a considerable cost reduction for CO2 separation and compression [4].
In addition, due to the high concentrated and pressurized CO2 rich stream, Pressurized Oxy-Fuel Combustion results in considerable CO2-compression costs reduction.
Further benefits are the reduced need heat exchange surfaces, and equipment volumes, which immediately turn in an overall plant cost reduction.
A wide amount of AFT data are available in literature, but lots of this studies are not reliable for the prediction of slag behaviour in the ISOTHERM process since results were obtained under firing atmospheres fairly different from the actual processing conditions typical of an oxy-combustion reactor.

MTT assay Determination of activity of mitochondrial and cytoplasmic dehydrogenases in living cells was performed using the MTT assay, which is based on the reduction of a colorless tetrazolium salt (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide, MTT) [19].
Statistical data analysis Statistical analysis was performed using the methods of variation statistics.
GR is an abundant flavin enzyme catalyzing reversible NADPH-dependent reduction of oxidized glutathione (GSSG).

KISTLER 7061B-type pressure sensors were used for measuring cylinder pressure and a set of Yokogawa DL750 Dynamic analyzer was used for data acquisition. 1.
With the BMEP rose to 0.605MPa, the difference of maximum cylinder pressure became inconspicuous in the wake of the reduction in fuel supply advance angle, the Maximum Cylinder Pressure reduced and its position moved away from TDC, the maximum cylinder pressure declined from 8.85 to 8.23MPa and its occurrence moment was later 2°CA than that of diesel.
No matter how working condition, the Maximum Cylinder Pressure reduced and its position moved away from TDC with the reduction in fuel supply advance angle.
The reduction of maximum combustion temperature greatly inhibits the generation of NOx emissions, this effects have been verified in earlier emissions testing directly.

Reduction of BAP concentration through dilution of CTP with a polymer suppressed carcinogenicity [4].
The results showed a substantial reduction of the BAP content in CTP when polyetherols of varying molecular weight were reacted with BAP.
Zielinski et al. [7] studied the effect of poly(ethylene terephthalate) (PET) process waste product on the reduction of BAP content in CTP.
Wavelength scanning method was taken to measure, the wavelength range was set between 200 nm ~ 400 nm, wavelength interval was set as 0.1 nm and wavelength-absorbance data was saved in the computer.

The circadian transmittance τc describes the factor of reduction of the circadian effect of light transmitted through glazing.
Data obtained from measurements of the samples are presented below in graphs where x axis represents the wavelength and y axis represents the relative spectral transmittance or reflectance.
A significant reduction in the amount of circadian transmittance when compared to light transmittance can be seen for the yellow sample.
This reduction of blue light income can lead to health problems and should be considered in the designing process [11, 23].

(2) NaOCl can bring the potentials of the specimens up and provide oxygen for reduction reaction in neutral and high pH conditions.
For low pH condition, hydrogen reduction reaction takes place.
Our preliminary results were not staightforward, and there were missing data to be retested.
This behavior can be explained that the reduction of pH at crevice and the pH6 level was an optimal potential difference for corrosion, where as the pH4 results in smaller potential difference, and the pH8 was too much potential difference under a given corrosion duration.

The FER2013 data set was used to train the Convolutional Neural Network (CNN) to identify emotions.
The paper concluded that CNN outperforms SVM when large data was involved. 3.Principal Component Analysis (PCA) An unsupervised statistical method is used for dimensionality reduction.
This makes the process of data exploration and visualisation easier by simplifying the complexity of high-dimensional data without interrupting its trends and patterns.
It is an effective method for modeling sequential data since it does not rely on pre clustered data per frame.
The amount of storage required to handle data increases with its size.

It does not need to access data in a specific order in time, like DRAM, MRAM, etc.
This mechanism will refresh all cache blocks regardless of whether their data content is invalid.
When you need to replace the data in the cache, there will be cases where the data to be replaced needs to be written back to the hard disk.
Our design method is to first write back the data in the cache when it needs to write data back to the STT-MRAM magnetic memory, first to determine whether there is continuous data in the cache where the current writer is located.
One is the value of the data block address from the current position of the writer and the rotation delay time; It is the time when the STT-MRAM magnetic memory writes the data block back to this address, the extra data is copied and rewritten because of the write amplification; the other is the time function generated by the number of times the data is frequently accessed recently, and its function is set.

Vibration data are collected through a data acquisition system, then tested and analyzed through statistical analysis.
For convenience of recording and processing the experimental data, each variable are coded as A, B, C, D and E.
MINITAB software was employed to analyze the experimental data.
Based on 95% confidence interval (α=0.05), the samples data were computed and analyzed.
Since the p-value is greater than commonly chosen α-levels, there is no evidence for a difference in deviation of actual laboratory data versus data calculated from model.

However, the main drawback of this group of damage detection methods is its limited applicability to operational data.
Its application together with classical modal filter allows for damage detection using operational data with other type of excitation.
However, the main drawback of this group of damage detection methods is its limited applicability to operational data.
In the simulation zero initial conditions were specified, exponential window was applied to the output data.
Comparison of ODS filter and modal filter applied on the same operational data As far as operational data is concerned, method presented in the article seems to be working better, in comparison with modal filter designed mostly for FRF data, as fewer distortions can be spotted in the output, especially around natural frequencies of a system.
