In this paper, a series of amphoteric polyacrylamide (PAM) with different molecular weight and charge were synthesized and used as retention and dewatering aids. Better products had been selected and tested under varied conditions. Effects of molecular weight, cationic charge density, degree of hydrolysis<br/> and other factors of PAM on retention and dewatering of papermaking were also considered. Finally, synthesized quaternary and tertiary ammonium amphoteric polyacrylamide were practised in paper mill trial.

This paper dealt with effect of dual component and micropartical retention system on papermaking. First-pass retention under dynamic drainage condition was studied in neutral and alkaline papermaking system. Cationic starches, amphoteric starches and amphoteric polyacrylamide were added prior to high shear force, then anionic microparticle (colloidal silica or bentonite clay) were added. The system is found to be very useful to improve filler retention. For mitigating unfavorable effect of interfering sub-stances [I] , anionic trash catcher (ATC)such as p-DADMAC was tested in this study.

Brushless doubly fed generator (BDFG) generally adopts double closed-loop vector control strategies. Owing to the influence of BDFG coupling parameters, the accuracy of feedforward decoupling parameters is very important; however, the complexity of the BDFG model makes its winding parameters difficult to identify. On the basis of the characteristics of the BDFG system control model and the decoupling control conditions, this study proposes a method for identifying the integrated coupling parameter. This method first uses particle swarm optimization to identify the coefficients of the current closed-loop transfer function. Then, the values of the integrated coupling parameters are calculated on the basis of the relationship between the coefficients of the current closed-loop transfer function and the integrated coupling parameters of the BDFG. This method bypasses the challenge of directly identifying BDFG winding parameters and can be used directly to design the controller. Experiments are performed using a 30 kW BDFG platform to prove the feasibility and effectiveness of the proposed method.

Amphoteric polymers have brought to papermakers' attention gradually. In this paper, a series of amphoteric starches with different cationic and anionic degree of substitution (DS) are prepared. Better product has been selected and used under different condition.<br/> As retention and drainage aids, amphoteric starches were used in 'shorter fiber length, weak strength and poor drainage bleached AQ-Soda wheat straw pulp. In neutral and alkaline papermaking system, when amphoteric starches contain 0.024anionic degree of substitution (DS), it is shown that the higher the cationic degree of substitution (DS) in amphoteric starches, the better the filler retention. The filler retention is improved 12.5%. 30.3%, and 35.1 % and 32.5% respectively by adding 1 % amphoteric starch LS-L2 -I (0.034), LS-L2-2 (0.040). LS-L2-3 (0.047) and LS-L2-4 (0.052). But the strength of handsheets is affected a little. By adding 2% Al2 (S04) J and 1.5% LS-L2-3 at pH 7.5, filler retention can be improved from 38% to 80%. and breaking length of sheet only decreases 3.2%. As dry strengthening aids, amphoteric starches were used in eucalyptus APMP. Amphoteric starches are used in eucalyptus APMP. The amphoteric starch LS-L2-2 is better dry strength aid. Adding 1% LS-L2-2 can improve breaking length 24.5%. burst index 42.9%. tear index 38.8%. folding endurance and density of the handsheets.

In this paper, a series of PAC (polyaluminum chloride) samples were prepared for rosin neutral sizing system. Some characters of PAC were discussed in detail. The experimental results show that it is possible to achieve neutral sizing when PAC is compounded with DRS(dispersed rosin size)instead of alum (aluminum sulfate).
PPNC: Privacy Preserving Scheme for Random Linear Network Coding in Smart Grid

In smart grid, privacy implications to individuals and their families are an important issue because of the fine-grained usage data collection. Wireless communications are utilized by many utility companies to obtain information. Network coding is exploited in smart grids, to enhance network performance in terms of throughput, delay, robustness, and energy consumption. However, random linear network coding introduces a new challenge for privacy preserving due to the encoding of data and updating of coefficients in forwarder nodes. We propose a distributed privacy preserving scheme for random linear network coding in smart grid that considers the converged flows character of the smart grid and exploits a homomorphic encryption function to decrease the complexities in the forwarder node. It offers a data confidentiality privacy preserving feature, which can efficiently thwart traffic analysis. The data of the packet is encrypted and the tag of the packet is encrypted by a homomorphic encryption function. The forwarder node random linearly codes the encrypted data and directly processes the cryptotext tags based on the homomorphism feature. Extensive security analysis and performance evaluations demonstrate the validity and efficiency of the proposed scheme.
