Scissioning: Chain scissioning or degradation results in a reduction in the average size (i.e. molecular weight) of the macromolecules present.
The experimental data pertaining to the molecular weight reduction for freeze-dried nanofibrillated cellulose at different doses of electron beam is shown in figure 9.
The experimental data showing changes in tensile modulus, elongation percentage and water absorption with electron beam dose in nylon-6 are shown in figure 10.
As an example, the typical differential scanning calorimeter (DSC) data (i.e. reverse heat flow versus temperatures) for epoxy coated carbon fiber samples (irradiated at different electron beam doses) is shown in figure 11.
There are so many other areas where electron beam induced modifications are widely applicable and still growing including flue gas treatment, semiconductor industries, preservation of food commodities, nuclear data generations as research applications and others.

FT-IR spectra results showed a reduction in AC-NaCl bands compared to other AC, which indicates less functional surface groups.
Tert-butylbenzene (TBB) adsorption capacity of 1 g of carbon at 0% NaCl-AC was 102 mg g-1, however a great reduction was noticed for 5% NaCl- AC with 35 mg g-1 TBB adsorption capacity, then 36 mg g-1 for 10% NaCl- AC , and 0 mg g-1 for both 15% NaCl- AC and 20% NaCl- AC. [23] explained and stated that the influence of NaCl on TBB adsorption capacity cannot be characterized by the TBB-carbon interactions only, but also by TBB-NaCl interactions.
A great reduction was observed for a series of complex bands in the frequency range from 1000 to 1260 cm-1 for AC-NaCl including C-O in carboxylic acids, alcohols, and esters and the P=O bond in phosphate esters.
Three weight reduction stages were observed.
A straight line was regressed for the data between iodine absorbance at 466 nm and its solution concentration.

Wavelet de-noising is a noise reduction method by transforming noisy data into the wavelet domain.
Hard threshold is to keep datum greater than the threshold, and all data less than the threshold are put to zero[7], the formula is as following:
Soft threshold is to put the data less than the threshold to zero, and subtract a constant from the data greater than the threshold, the formula is:

Moreover, the fatigue limit theory was used to obtain the best relative clearance, which can provide theoretical data to the bearing structure optimization.
The relationship between relative clearance and temperature firstly displays the tendency of reduction and then the trend of increment.

The experiments have shown that sufficient data have been obtained to give confidence in the reinforcing mechanism of stay in place construction formwork, and future work need only be focused on formwork design and standardization.
Regarding the structural behavior, it was found that the reinforced concrete Coffor walls are more ductile compared to the conventional reinforced concrete walls while a reduction in their capacity was observed.

Compressed sensing (CS) is a new Compressed sensing (CS) is a new technique for simultaneous data sampling and compression.
But, the measurement matrix used in [8] is changeless and operator at the same rate, which brings a certain waste of data, because each small block has different complexity.
We treat an image or higher-dimensional data by vectorizing it into a long one-dimensional vector.
In this process ,the measurement vector y is just a linear combination of the K columns of whose corresponding ,meanwhile, the any K-parse or compressible signal is not damaged by the dimensionality reduction from down to .Then we could use a reconstruction algorithm to recover x from the measurements y.

The extensions take the asymptotic behavior of the bending test for L/h = 0 and L/h = ∞
in account while providing the best fitting to the measured data.
Working with new type (e.g. basalt fiber) long fiber reinforced polymers [1, 2] it is important to have reliable knowledge of testing methods and data from the conventional (glass, carbon) type composites.
Classical beam theory [12] was used to evaluate the experimental data of three-point bending test.
Atkinson: Reduction in tensile and flexural strength of unidirectional glass fibre-epoxy with increasing specimen size.

There were 4 period remote sensing data, which was acquired respectively in June 2009, April 2010, June 2011 and July 2012, and field investigation were applied in this articles to study these mining collapsing.
The identification marks of mining collapsing The author did some investigation work about mining collapsing which caused by coal mining in Jining area, the main data is remote sensing image which was acquired in June 2009.
And the mining collapsing water pit could be distinguished with lake through compare with historical data and some field investigation.
It can play an important role in the investigation and study works about mining collapsing, and can make contribution to the disaster prevention and reduction works.

With increasing number of
ECAP passes and cold rolling reductions, the initial coarse grained structure in the as-received
material was transformed gradually into an ultrafine grained microstructure with an average grain size
of 0.2~0.3 µm.
When the experimental data point of hardness deviation is plotted again with the gradient of hardness obtained in figure upon accumulated strain, their tendency shows very well correspondence, as is shown in figure 6 (b).
