The EEZVI-UASB technique was used for processing swine wastewater and for studying the correlation among EEZVI electrode voltage, concentration of organic matters and denitrification rate of contribution to solve the passivation of ZVI electrode surface and realize the stable and efficient operation of the anammox technique. The results showed that the starting time needed by the technique for processing swine wastewater was shorter at (35±1)℃, pH 6.80-7.10 and electrode voltage 0.60 V. The removal rates of NH4+-N and NO2--N were able to keep at a high level, with removal rates of >90.00% for NH4+-N and >96.00% for NO2--N, and an average removal rate of TN>90.00%. When EEZVI electrode voltage was 0.60 V, AAOB activity was 91.10 mg/(g·d). In the EEZVI-UASB system, the dominant bacteria belonged to the genus of Pseudomonas, as confirmed with a similarity value of 97% by PCR amplified 16S rDNA analysis. Reactions like denitrification, anaerobic ammonium oxidation and methanation occurred simultaneously, but the dominant reaction was anammox, whose contribution rates for TN removal were 54.10%-93.30%. The contribution rates of denitrification and other reactions for TN removal were 6.70%-45.90%. ©, 2015, Editorial department of Molecular Catalysis. All right reserved. Source

Establishing electronic portfolio is one of the effective approaches to promote teachers' professional growth. It enable us to give teachers developmental evaluation, and can facilitate the teaching research as well as academic communication between teachers. This article applied the service which is based on moodle platform to the design of electronic portfolio with the purpose of helping teachers' professional growth. © 2014 IEEE. Source

Human 3D garment modeling is of great importance for clothing design and computer vision, and the existing computer aided garment system cannot effectively find threedimensional style influence of their design only when the sample dress have been produced. The proposed human 3D garment modeling system is constructed using a library of garment models and garment parts, in which different type of garments are utilized, including skirts, coats, shirts, and trousers. Particularly, we describe the human 3D garment model as a graph, and an improved mesh is denoted as 1) vertex set, 2) edge set and 3) tetrahedron set. Afterwards, we convert the human 3D garment modeling problem by integrating two energy functions. To demonstrate effectiveness of our research, we use a normal female garment design to prove that our method is effective to model human 3D garment. © 2016 IEEE. Source

Social networks have been widely used, providing people with great convenience but also yielding potential risk of privacy disclosure. To prevent attacks based on background information or query that may expose users' privacy, we propose a method to achieve k-anonymization for network graphs. The concept of similarity matrix and that of the distance between a vertex and a cluster are defined based on vertex connectivity. On this basis, we present a clustering-based graph partitioning algorithm to obtain the K-anonymized graph of a certain network graph. Simulation experiments are conducted to analyze and verify the effectiveness of our algorithm. © 2015 IEEE. Source
