Design 3D Garments for Scanned Human Bodies
Dongliang Zhang,Jin Wang (사)한국CDE학회 2013 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8
In this study we present a 3D garment design method for scanned human bodies. Firstly, a slicing method is proposed to reconstruct a symmetric body from a scanned human body to make it suitable for garment design. Secondly, a sketch modeling method is used to interactively create the garment surface based on the new body. Thirdly, seam lines are drawn on the garment surface, and then a flattening algorithm is employed to design 2D patterns. Finally, a seam line template is used to design the same style for different bodies. Experiments show that the resulted garment well fits the scanned body. Our method provides an efficient design tool for customizing garments in the fashion industry.

Studies of the genetic diversity and population structure of Oenococcus oeni (O. oeni) strains from China are lacking compared to other countries and regions. In this study, amplified fragment length polymorphism (AFLP) and multilocus sequence typing (MLST) methods were used to investigate the genetic diversity and regional evolutionary patterns of 38 O. oeni strains isolated from different wine-making regions in China. The results indicated that AFLP was markedly more efficient than MLST for typing O. oeni strains. AFLP distinguished 37 DNA patterns compared to 7 sequence types identified using MLST, corresponding to discriminatory indices of 0.999 and 0.602, respectively. The AFLP results revealed a high level of genetic diversity among the O. oeni strains from different regions of China, since two subpopulations and an intraspecific homology higher than 60% were observed. Phylogenetic analysis of the O. oeni strains using the MLST method also identified two major phylogroups, which were differentiated into two distinct clonal complexes by minimum spanning tree analysis. Neither intragenic nor intergenic recombination verified the existence of the clonal population structure of the O. oeni strains.
Simulation study on CFRP strengthened reinforced concrete beam under four-point bending

This paper presents numerical modeling of the structural behavior of CFRP (carbon fiber reinforced polymer) strengthened RC (reinforced concrete) beams under four-point bending. Simulation of debonding at the CFRP-concrete interface was focused, as it is the main failure mode of CFRP strengthened RC beams. Here, cohesive layer was employed to model the onset of debonding, which further helps to describe the post debonding behavior of the CFRP strengthened RC beam. In addition, the XFEM approach was applied to investigate the effects of crack localization on strain field on CFRP sheet and rebar. The strains obtained from the XFEM correlate better to the test results than that from CDP (concrete damaged plasticity) model. However, there is a large discrepancy between the experimental and simulated loaddisplacement relationships, which is due to the simplification of concrete constitutive law.

Microblogging services (such as Twitter) are the representative information communication networks duringthe Web 2.0 era, which have gained remarkable popularity. Weibo has become a popular platform forinformation dissemination in online social networks due to its large number of users. In this study, a microbloginformation dissemination model is presented. Related concepts are introduced and analyzed based on thedynamic model of infectious disease, and new influencing factors are proposed to improve the susceptibleinfective-removal (SIR) information dissemination model. Correlation analysis is conducted on the existinginformation dissemination risk and the rumor dissemination model of microblog. In this study, web hyper isused to model rumor dissemination. Finally, the experimental results illustrate the effectiveness of the methodin reducing the rumor dissemination of microblogs.

In this work, the trend in the performance of carbon fiber (CF) and its composite during self-polymerization of polydopamine (PDA) at carbon fiber surface was investigated by varying the self-polymerization time of dopamine in an aqueous solution. Research has shown that the PDA coating elevated the surface roughness and polarity of the inert fiber. The tensile strength of single carbon fiber was significantly improved, especially after 9 h of polydopamine self-polymerization, increasing by 18.64% compared with that of desized carbon fiber. Moreover, the interlaminar shear strength (ILSS) of CF-PDA9-based composites was 35.06% higher than that of desized CF-based composites. This research will provide a deep insight into the thickness and activated ingredients of dopamine oxidation and self-polymerization on interfacial compatibility of carbon fiber/epoxy resin composites.

The Microstructure and Magnetic Properties of Melt-Spun CeFeB Ribbons with Varying Ce Content

The microstructural and magnetic properties of melt-spun ribbons with thecomposition (CexNd100-x)30FebalCo4Ga0.2B0.92 (where x = 50, 60, 70, 80, and 90)were investigated. The ribbons were examined with Scanning ElectronMicroscopy (SEM), Transmission Electron Microscopy (TEM), and VibratingSample Magnetometry (VSM). It was found that the grain size of the ribbons ison the nanometer scale, and the grain size decreases with decreasing Ce content. The magnetic hysteresis loops showed that the magnetic properties of theribbons gradually deteriorated with increasing Ce content. This is because themagnetic polarization (Js) and magnetocrystalline anisotropy field (HA) ofCe2Fe14B are smaller than those of Nd2Fe14B. Furthermore, from the initialmagnetization curve it was found that increasing the Ce content changes thecoercive force mechanism to the nucleation mechanism. When Ce contentaccounts for 90% of total rare earth metals, the coercive force mechanismmainly appears to be a nucleation mechanism.
Microbial transformation of ginsenoside Rg3 to ginsenoside Rh2 by Esteya vermicola CNU 120806.
Hou, Jingang,Xue, Jianjie,Wang, Chunyan,Liu, Lei,Zhang, Dongliang,Wang, Zhen,Li, Wei,Zheng, Yinan,Sung, Changkeun Springer 2012 World journal of microbiology biotechnology Vol.28 No.4
<P>In the present investigation, we successfully employed a cell-free extract of Esteya vermicola CNU 120806 to convert ginsenoside Rg3 to Rh2. Three important factors including pH, temperature and substrate concentration were optimized for the preparation of Rh(2). The optimal condition was obtained as follows: 50C, pH 5.0 and substrate concentration of 3 mg ml(-1). The yield of conversion was up to 90.7%. In order to identify the specificity of the β-glucosidase activity of Esteya vermicola CNU 120806, ginsenoside Re (protopanaxatriol saponins) was treated under the same reaction system. Interestingly, no new metabolite was generated, which elucidated that the enzymatic process only occurred by hydrolysis of the terminal glucopyranosyl moieties at the C-3 carbon of ginsenoside Rg(3). The crude enzyme extract can be used for commercial ginsenoside Rh(2) preparation.</P>
