The MIP results were obtained in the form of raw data representing cumulative intruded volume versus pressure curves.
As stated earlier raw data so obtained were processed to obtain a general form of the pore size distribution equation as discussed in the next section.
Reduction in w/c ratio results in reduction in pore size as well as the size become uniform, because the original water filled spaces in the unhydrated paste are smaller and relatively more uniform sizes, in a well dispersed particulate system.

The experimental modal data, i.e. the eigenfrequencies � � �and mode shapes � � �, are obtained from measurements.
The modal data are identified before and after applying the damage.
Experimental modal data.
Conclusions A FE model updating method using modal data is presented.
Furthermore, a good correlation between the experimental and the updated numerical modal data is obtained.

The input data for Static analysis b) Dynamic Analysis Linear dynamic studies are based on frequency studies.
The input data to optimize the structure are presented in table 1.
The output data for Static analysis The output data from a dynamic analysis (fig.3) in SolidWorks typically includes: Displacement: The visual graph of the displacement of the analyzed structure (fig.3.a).
The output data from a dynamic analysis Every structure has the tendency to vibrate at certain frequencies, called natural or resonant frequencies.
Mode Shapes and Frequencies of the clamping components The output data from the design study in order to optimize the structure are weight variation (fig.5) and the variation of the safety factor fig.6 for 53 out of 281 possible scenarios for the entered input data.

However, reducing the magnetic grain can cause unstable data in storage and thermal fluctuation.
The data bit might change to opposite direction.
Both effects can cause error of data and performance degradation of BPMR during read back process.
In this paper, we propose an error correction coding scheme to correct the error of read back data.
Where k is the number of data symbols being encoded, and n is the total number of code symbols in the encoded block.

And this paper use the test system of Split Hopkinson Pressure Bar (SHPB) to survey the impact test action of different porosity red sandstone in different coupling medium in order to obtained the dynamic waveform of fluid-solid coupling red sandstone under impact loading using theoretical analysis and laboratory data.
He found that stress wave through the broken rock specimen will have a greater attenuation and reduction of the dynamic strength of rock.
Fig.5 The incident wave and reflected wave oscillogram of red sandstone in different coupling medium Fig.6 The transmitted wave oscillogram of red sandstone in different coupling medium Conclusions This chapter is Split Hopkinson Pressure Bar (SHPB) test system on the red sandstone under different porosity and coupling state impact test, through the collation and summarized of data, obtain the following conclusions: (1) Analyzed the dynamic performance of different porosities red sandstone under similar impact velocity, the results showed that porosity is one of the main factors affect on the dynamic performance, the higher the porosity, the smaller the transmission peaks.

This study is expected to provide useful data for the efficient physical separation of metallic components from printed circuit boards scraps.
If such an aim is achieved, then not only is energy saved by reduction of the amount fines produced, but any subsequent separation stages become easier and cheaper to operate [6].
Conclusion This study is expected to provide useful data for the efficient mechanical separation of metallic components from printed circuit boards scraps.

In this paper, the above mechanisms will be illustrated by a set of data pertaining to titanium alloys.
In fact, experimental data show that the hot deformation behaviour of the b phase in titanium alloys is quite similar in ferritic steels or the bcc a phase of standard steels, as well as in aluminium alloys, in spite of their different crystallographic structures, which will be illustrated by some examples.
Moreover, at larger strain rates, whereas the migration rate is likely to be larger due to stronger driving forces, it is counterbalanced by the reduction of the migration time, which results in much smaller boundary migration distances.

The data demonstrated that MAE could be a fast and reliable method for quantitative analysis of PEP.
Recently, polysaccharides from edible seaweeds have provoked interest as sources of novel potential antioxidants, since more and more published data indicated that plant polysaccharides in general had strong antioxidant activities.
Recent years, some new extraction techniques, which enable automation, shortening extraction times and reduction of organic solvent consumption, have been developed.

Superimposed on the frequency histograms in Fig. 3 are the lognormal and Rayleigh probability distributions showing that the former gives best fit of the data.
A more rigorous comparison of the experimental data with Eqs (1) and (2) was achieved by plotting, for a given grain size class, iD , the residue of the expected and actual frequency, i.e
This parameter is plotted in Fig. 4 for all grain size classes after annealing for 1h at 400 to 500 °C (for clarity, data of other annealing conditions are not given).
At longer annealing times (3h) at 500 °C, the data are more dispersed at the largest grain diameters indicating some deviation from invariant coarsening behaviour.
Superimposed on the histograms is the best fit of the data for the lognormal and Rayleigh probability distribution (see text).

The general functions of CMMS program are designed to organize the data, evaluate the data, and report the information via the internet.
Especially, for the plastic injection machine, the program cannot be added, deleted or edited the data immediately.
The PM plan is derived from the collecting data in every month and evaluating the results into the fixing plan.
The CMMS program divides the users into three groups for the convenience and security in viewing and managing the data.
The developed database is easy to add, delete or edit the data quickly whenever the machine is breakdown.
