The first heating scan was employed to obtain the curing data.
The plastifying effect of the ionic liquid resulted in the reduction of the final dynamic-mechanical properties of the systems.
Figure 4 shows that the increase in the ionic liquid content influenced the reduction of the maximum curing temperature.
The reduction in Tg in the greater presence of IL confirms its plasticizer effect.
Table 1 organizes the cure and Tg data.

Image Compression Technology Based on the Analysis Theory of Wavelet Hui Guo1, a , Jie He2, b 1 Department of Electronics Information Engineering,Wuzhou University,Wuzhou, 543002,China 2 Computer Science Department,Wuzhou University,Wuzhou, 543002,China a,b huiguo12@yeah.net Keywords: Image compression; Wavelet transform; Mallat algorithm; Abstract.Due to the huge amount of image data transmission conditions and the existing relative low, makes the image compression become inevitable, key technology of image compression for image data transform to transform the quantitative data, as well as to the quantitative data, after the entropy coding.And this article USES the 2 d Mallat of wavelet image compression algorithm is a kind of common image compression method of wavelet image compression algorithm is the core.
Introduction With modern information society for communications business requirements growth, images, communication and network capacity of the increasingly prominent contradiction between, especially those with large amount of data digital image communication, it is difficult to transfer and storage.
The basic principle of image compression Image coding point of research is allowed in a certain image distortion of conditions (including visual effect,), such as the realization of image information data compression.
The system will come from the source image signal after PCM encoder for pulse code modulation (PCM), the compression encoder to compress image data unrelenting, then eliminate the image data redundant code words, image compression of the basic principle as shown in figure 1 shows.
The above results arithmetic coding The algorithm for the 4 x 4 pieces of 128 bit data, plain area only two coding, time with a flat area 19 coding, time with a texture area 36 coding, texture in 2 + zone 16 x 5 + 6 + 6 = 94 a coding.

The concrete gets less workable (stiff) as the proportion increases, according to the workability data.
The design was based on import data design using Design-Expert 13.0 version.
In Fig. 4 data, the consistency, or the amount of water needed to create a paste of 20% WPPA by weight of PLC is the highest, while the consistency of the control is the lowest.
The delay in the setting time could be attributed to the reduction in surface area of the cement and reduction in the quantity of tricalcium silicate in the WPPA-blended cement paste [36, 39].
Additionally, the reduction of the strength with increased WPPA is due to the high replacement of PLC by weight of WPPA, which causes reduction of hydration reaction [22, 28, 33, 49].

Therefore, leakage energy reduction technique is primarily aimed at reducing the sub-threshold leakage current.
There are several reduction techniques for leakage dissipation, such as dual threshold CMOS (DTCMOS), multi-threshold CMOS (MTCMOS) power-gating technique, stacking transistor techniques, and variable threshold CMOS (VTCMOS), etc [1, 2].

After long-playing research and continuous comparison with historical data, meteorologists recognize that the causes determining the climate state and change don’t exist in the atmosphere, but depend on overall interaction of climate system composed of the air, water, ice, rock, and other several major factors.
Relevant data shows that, if the carbon dioxide concentration increases one time, the average temperature of global surface will rise 1.5~3.5℃.
Reduction or disappearance of vegetation and marine plankton reduces carbon dioxide stored in plants and used for photosynthesis, so as to make the greenhouse gases and global temperature increase further.
Because the forest has these special features in addressing climate change, “Kyoto Protocol” sets two ways: industrial direct reduction and forest indirect reduction.
Energy-saving and emission reduction and climate change also needs the participation of the whole people.

According to the main results [6], based on experimental data and Computational Fluid Dynamics (CFD) studies, it was concluded that it was possible to combine in a single device, high separation efficiencies with low Euler numbers (Eu).
In turn, the anticlockwise rotation has also played a favorable effect on the Euler number, with average reductions 12.3% compared to conventional separator H11 (0 rpm).
The smallest Euler number was reached when the largest anticlockwise rotation was used in hydrocycloning (3000 rpm) leading to a reduction of approximately 17.1% in the analyzed response.
According to the experimental data of underflow-to-throughput ratio for the hydrocyclone under study, it can be seen that neither the direction nor the intensity of rotation has played significant effect in this response.
In turn, the clockwise rotation played an adverse effect on the overall efficiency, with an average reduction around 18.3%.
